-# PC
-
-Prompt context only: keep hard constraints, short rationale, and traps already hit. Implementation details belong in source headers and tests.
-
-## Boundary
-
-Single-process Electron app. Main is a Node backend, renderer is vanilla HTML/CSS/JS, and IPC is the only app communication path.
-
-- No HTTP server, no occupied port, and no local auth layer in main.
-- Renderer access goes through the `contextBridge` allow-list API `window.orkas.{invoke, stream}`.
-- No TypeScript/JSX/bundler in the renderer; classic scripts only.
-- `src/main/preload.js` must remain `.js`; preload does not run the tsx hook.
-- LLM calls use the in-process `core-agent` loaded dynamically through `import('#core-agent')`.
-- Local CLI agents are the explicit child-process exception. `features/local_agents/runner.ts` is the only CLI dispatch spawn path.
-- MCP stdio connectors spawn only through `features/connectors/mcp-client.ts`.
-- User data is mostly JSON/JSONL for readability and sync friendliness; sqlite is reserved for the KB vector store.
-- macOS and Windows are primary. Platform branches need platform-specific verification.
-- New npm dependencies require prior discussion; renderer third-party JS/CSS goes under `src/renderer/vendor/`, not npm.
-- API profile routing goes through existing account/marketplace API-base helpers. Do not hard-code production domains.
-
-## Layering
-
-- `ipc/`: validate args and call features; no business logic.
-- `features/`: business workflows; may use storage, paths, prompts, model, util, and sibling features.
-- `model/` and `model/core-agent/`: model-call adapters and tool plumbing; do not read/write business data under `data/`.
-- `util/`: pure/foundational helpers; never reverse-import features/model.
-- `storage.ts`, `paths.ts`, and path sandbox helpers are the storage/path choke points.
-- `i18n.ts` may read locales but must not import features/model.
-
-Additional rules:
-
-- Feature functions handling user-private data take `userId` as the first argument.
-- Boot-time async work registers through `util/boot_init.ts`, not raw startup timers or async IIFEs.
-- `#core-agent` is dynamic-import only. Static import loads dependencies before the SDK timeout patch and can break ESM resolution.
-- `sdk-timeout-patch.ts` must run in `index.ts` after logger init and before feature imports.
-- New core-agent tools must be registered in `tool-catalog.ts::TOOL_CATALOG` and runner wiring. Tool descriptions live in SDK `tools[]`, not in a duplicated prompt tool list.
-- File-class tools must check `util/path-sandbox.isPathAllowed` at entry.
-- Tool results go through `util/tool-result-cap.ts`.
-
-## Prompt Files
-
-`src/main/prompts/*.md` is LLM-facing source. It must not contain:
-
-- Product/brand names.
-- Real OS paths.
-- Project source/data directory literals.
-- Hard-coded tool catalogs.
-
-Runtime-volatile prompt fields go in one trailing `## Runtime injection` section. Static rules stay first so cache prefixes remain stable. Chat prompts must point to platform creator skills for agent/skill authoring details; do not duplicate field schemas or category tables inline.
-
-Residual shared prompt rules should have one canonical source, with downstream prompts carrying only a short reference.
-
-## Data Domains
-
-All user-scoped data lives under `<container>/data/<uid>/{cloud,local}/`.
-
-- Top-level data may contain only `users.json`, `logs/`, and user directories.
-- Hosted builds use `anonymous` while logged out and the Server account uid while logged in. OrkasOpen first boot keeps the legacy generated local id.
-- `uid` is an opaque single path segment. Do not parse it or embed it into session ids.
-- `cloud/` is syncable user-private state: chats, resumable sessions, attachments, artifacts, saved apps, contexts source files, memory, custom agents/skills, projects, marketplace install manifest, auto tasks, and user config.
-- `local/` is machine-private state: account/session cache, marketplace installed content, caches, indexes, vector DB, workspace selection, tool-result spills, local-agent archives, and dev archives.
-- Never cache uid-derived paths as module-level constants. Get the active uid at use time.
-- Platform agents/skills are marketplace installs in `local/marketplace/...`, reconciled from the cloud install manifest. Hand edits are overwritten unless made through dev-mode platform editing and republished.
-- Project membership is an index field on a conversation. Do not encode `project_id` into paths, cids, or session ids.
-- Project lists are directory scans; do not restore an aggregate `projects/_index.json`.
-
-## Account, Sync, And OrkasOpen
-
-- Hosted account login uses the Server `SessionMgr` pair (`user_id`, `session_id`), stored through `util/local-secret-store.ts`. There is no client refresh-token loop.
-- Authenticated HTTP calls carry `user_id` + `session_id`; WebSocket URLs carry the same pair only where required.
-- Optimistic login state may come from disk, but network revalidation must refresh or clear it.
-- Private hosted secret backends stay behind the local-secret facade. Do not import `features/hosted_secrets/` outside that facade.
-- Account, relay, voice, sync, billing, and marketplace-dev surfaces that depend on hosted Server features are stripped from OrkasOpen according to `OpenSource/SyncCode/strip-rules.json`. Do not add new hosted-only files without updating strip rules.
-- PC never writes `private/<oauth_user_id>/manifest.json`; Server `/sync/manifest/commit` is the only writer.
-- Cloud sync paths use OAuth `user_id`, not an unrelated local uid.
-- Object transfers under the sync prefix go through `features/sync/transport.ts`.
-- Manifest entry `size` is the COS-stored byte count. Do not treat it as plaintext bytes.
-- New sync triggers funnel through the existing dirty/sync engine, never an ad-hoc uploader.
-- Local data must not be marked dirty for cloud sync.
-- Cloud sync and voice are entitlement-gated by Server. Renderer failures from subscription gating are expected UX states, not sync/voice bugs.
-
-## Release Relay
-
-This release branch uses the pre-main relay shape:
-
-- iOS is a remote control. PC runs all agent work and delivers relayed commands through normal group-chat send/bus flow.
-- `features/relay/commands.ts` long-polls Server and must not add a fixed inter-poll delay; Server controls cadence.
-- `features/relay/sync.ts` mirrors relay-enabled conversations through bus events: messages, plan, state, and batched process events. Do not replace this with main's bounded conversation-list snapshot unless the matching Server/iOS code lands here.
-- PC pushes agent/skill account-index snapshots for iOS pickers. This release does not push project/workspace state to iOS.
-- No server-side agent execution and no cloud worker path. The iOS cloud option remains disabled until product/backend support exists.
-- Keep PC sidebar updates for iOS-triggered activity on the normal conversation list path; do not add a parallel display path.
-
-## Conversations And Group Chat
-
-Session ids are `<kind>-<tail>`; user scoping comes from the path root, not the filename. Add new kinds by updating the session-store allowlist and all session-kind gates.
-
-Main rules:
-
-- Commander, agent-worker, skill-edit, agent-edit, and one-shot sessions are separate session files from UI message lists.
-- Group chat dispatch goes through `features/group_chat/bus.ts::enqueue`. Do not create parallel enqueue/scheduling paths.
-- Agent workers read only their visibility slice; never the full conversation jsonl.
-- LLM dispatch is structured (`dispatch_to`, `plan_set`), not `@name` in prose.
-- `plan_set` owns plan writes. Retry/skip mutates plan state and reconciles through the plan executor; it does not send the original user message again.
-- User abort is never a transient retry. Network retry patterns must stay network-specific.
-- Group abort is the single stop path for all actors.
-- Infinite-loop protection is turn-count based, paired with idle timeout; do not replace it with total wall-clock timeout.
-- Expert signals emit only from the established group-chat chokepoints or model callbacks drained by bus. Model code must not import signal emitters directly.
-
-Attachments:
-
-- Main conversation attachments are stored under the current cid with zero eager preprocessing.
-- Read/edit tools are scoped to active workspace plus current attachment dir.
-- `stat_file` precedes `read_file` for pdf/docx.
-- Video attachments are display-only, not model input.
-
-## Artifacts And Saved Apps
-
-- `create_artifact` writes only to `<uid>/cloud/chat_artifacts/<cid>/<artifactId>/`.
-- `chat-app://` serves only validated artifact files through `features/chat_artifacts.ts`; never expose `window.orkas` or IPC to the iframe.
-- Artifact-to-app communication is the validated `postMessage` contract and routes back as a normal user message.
-- Saved apps live only under `<uid>/cloud/saved_apps/<appId>/` and open through the saved-app resolver.
-- Editing a saved app is fork-and-modify via a new conversation and attachment bundle; it is not in-place mutation.
-- Do not widen artifact served extensions or iframe sandbox privileges without a security review.
-
-## Skills, Agents, And Marketplace
-
-- Skill sources are custom cloud skills plus platform local marketplace installs. Custom overrides platform by id.
-- Agent/skill category belongs in the spec (`agent.json` or SKILL.md frontmatter); install freshness belongs in `_install.json` / install manifests.
-- Creator skills (`agent-creator`, `skill-creator`) are the canonical source for authoring semantics, validation details, and category candidates.
-- Creator skill paths under the PC data root: `<uid>/local/marketplace/skills/16e1bfcb3426/SKILL.md` (`agent-creator`) and `<uid>/local/marketplace/skills/efb0fe5d9664/SKILL.md` (`skill-creator`).
-- Platform agent/skill primary text is English. Descriptions are bilingual (`description_zh`, `description_en`); other UI languages fall back to English.
-- SKILL.md frontmatter allows only the approved spec fields. External dependencies are prose in the body, not runtime-managed metadata.
-- Skill id is the directory name; display name is frontmatter `name`. Do not re-couple them.
-- Same display-name marketplace/platform skills with different ids must stay visible by internal read id. Custom may shadow a same-name platform skill, but platform-platform duplicates must not be globally deduped.
-- `agent.skill_list`: missing means legacy unfiltered, empty means no skills, non-empty means strict subset.
-- CLI-backed agents ignore SkillLoader and own runtime settings through the create/edit form, not the LLM-authored workflow.
-- Skill execution goes through `bin/run-skill.cjs`; do not bypass the runner.
-- Component enabled/disabled state is user preference and must not be written into specs.
-
-Dev-mode marketplace editing/upload/delete is hosted/private tooling. Runtime gates and packaging strip rules must both protect it.
-
-## Connectors
-
-- Provider client credentials live on the Server. PC starts OAuth via Server and receives grants through the deep link callback.
-- Connector metadata may remain plaintext, but token-bearing grant/DCR/transport data lives inside per-instance `secrets_enc`.
-- `transport` is encrypted because resolved transport can contain access tokens.
-- Do not reuse account-login modules/namespaces for connector authorization.
-- Tool exposure uses the umbrella pattern: a `## Connectors` block plus `list_connector_tools` and `call_connector_tool` meta-tools.
-- Never inject every MCP action as a flat SDK tool list.
-- Connector visibility is live connected state, user enable toggle, and session-kind scope.
-- Commander (`gconv`) gets block + list + call. Agent-edit gets block + list only. Agent workers, skill edit, one-shots, CLI, reflection, and memory extraction get none.
-- Non-connected connectors are invisible to the LLM; do not add disconnected/error status hints to prompt blocks.
-- No free-form custom MCP-server UI or API-key install path without a product/security plan.
-
-## Knowledge Base
-
-- User-managed context source files live in cloud; derived vector DB and model config live in local machine-private `.kb`.
-- Embedder/model config is fixed unless a full rebuild/migration is designed.
-- Do not use worker_threads for multiple ONNX sessions; use child-process isolation for true parallelism.
-- The model may access contexts only through KB tools, not shell/file scans of the contexts dir.
-- Chunking/search/vector-store shared logic should reuse the existing utilities instead of new bespoke parsers.
-
-## Renderer
-
-- Classic scripts only. Add new script files to `index.html`.
-- New `window.orkas.*` APIs require a main IPC handler; renderer shim routes are centralized.
-- Markdown rendering uses `renderMarkdown`; dashboard directives and schema references change together.
-- Do not append cache-busting query strings to renderer resources.
-- Renderer icons are centralized in `modules/icons.js`; do not hard-code SVG paths or use emoji icons.
-- Reuse shared UI classes and modifiers. Do not create near-duplicate cards/buttons/chips.
-- Before adding overlays/popovers/dialogs, check existing z-index tiers.
-- Name-scanned inventory lists sort by display name unless the list's order is itself meaningful.
-- Keydown action shortcuts in inputs/textareas must ignore IME composition (`e.isComposing || e.keyCode === 229`).
-- Long-running user actions need visible progress; read-heavy network views should use stale-while-revalidate when staleness is acceptable.
-
-## i18n
-
-- Visible UI strings go through `src/{renderer,main}/locales/*.json` and `t(...)`.
-- Main-generated text uses main locales; renderer chrome uses renderer locales. Shared surfaces may need both.
-- Dynamic renderer text must re-render on `i18n-change`.
-- Agent/skill descriptions use `description_zh` for Chinese and `description_en` otherwise.
-- Prompts, logs, telemetry event names, and user content are not i18n-ed.
-
-## Logging, Telemetry, Privacy
-
-- Use `createLogger('<module>')`; do not use `console.log` for app logging.
-- Recoverable failures log `warn`; broken invariants log `error`.
-- Sensitive fields must be redacted before logs/telemetry.
-- Telemetry goes through `Monitor.click/event/error/identify`; payloads contain only ids, types, counts, lengths, or coarse status.
-- Expert-signal files are local-only and may contain raw excerpts. Never copy their content into logs, telemetry, or cross-machine channels.
-
-## Tests And Dev Workflow
-
-- Start PC with `cd PC && ./run.sh`.
-- Run tests with `npm test`, not `npx vitest`; the test script manages sqlite ABI swapping and rollback.
-- If sqlite ABI is broken, run `npm run rebuild:sqlite:electron`.
-- Tests should cover business invariants, recovery paths, concurrency, cross-layer contracts, and text-processing traps.
-- Do not test typing-only wrappers, trivial getters, happy-path-only cases, or implementation internals.
-- LLM-output parsers/sanitizers need fixture sets for both accepted real shapes and rejected look-alikes.
-- Pure renderer functions may expose a guarded CommonJS bridge for tests; DOM/i18n/IPC code should not.
-
-## Do Not
-
-- Put business logic in IPC handlers.
-- Spawn CLI agents or MCP servers outside the approved choke points.
-- Store user data outside `<uid>/{cloud,local}/`.
-- Hand-edit local config/marketplace install files outside the owning UI/dev flow.
-- Bypass path sandboxing, locks, file indexer, sync transport, or artifact/saved-app resolvers.
-- Add eager attachment extraction or automatic pdf/docx fallback in `read_file`.
-- Add LLM total wall-clock timeouts or lock wait timeouts; use the existing idle/watchdog semantics.
-- Reintroduce aggregate project indexes, uid-bearing session ids, flat connector tool injection, server-side relay agent execution, or parallel group-chat dispatch paths.

-## Screenshots
+## Why Orkas
 
-![Orkas home screen](./resources/app-ui/home-en.jpg)
+- **A super-powered Commander** — understands context, breaks down goals, chooses the right agents, skills, connectors, and tools, and directly handles analysis, writing, research, file work, and automation when no specialist is a better fit.
+- **Drives the open-source ecosystem** — plug in external CLI coding agents (Claude Code, Codex, OpenCode, Cline) and onboard open-source projects like HyperFrames as local tools, all coordinated by the same Commander.
+- **Local-first by design** — conversations, files, API keys, knowledge bases, and custom agents all stay on your disk. Model calls go straight from your machine to the provider — never through Orkas servers.
+- **No vendor lock-in** — mix providers across agents: one on Claude, another on DeepSeek, another on a local endpoint.
+- **Agents that get better** — each agent has its own private skills and memory, and improves through reflection after each task.
+
+> ⭐ If Orkas is useful to you, a star helps more people find the project.

-> Full design and hard constraints → [`CLAUDE.md`](./CLAUDE.md)
+Packaged installers for macOS and Windows. Linux runs from source today — see [Quick start](#quick-start).
 
-### Group chat: visibility slicing + a single scheduling primitive
-
-In one chat there's a commander, N agents, and you — but **each agent does not see the same conversation**.
-
-- **Visibility slicing** — the main conversation is one full jsonl; each agent only gets a slice in its own `visibility/<aid>.jsonl`: `from==me ∨ to∋me ∨ mentions∋me`. The worker only reads its own slice and **never the full main conversation** — saves tokens and prevents private context from leaking across agents
-- **One scheduling primitive** — every dispatch (the commander's `dispatch_to`, the user's `@` in text, steps split out from a plan) funnels into the same `enqueue` primitive. No parallel routing paths. Any new dispatch path must go through it, to avoid scattered "who-can-wake-whom" rules
-- **Shared plan** — when multiple agents collaborate, the commander writes the progress into one `plan.md`, visible to every member
-
-### Agent dispatch: structured channels, not `@` in prose
-
-LLMs love using `@` as a markdown decoration — recognizing `@` in prose as a dispatch signal triggers false positives over and over. So:
-
-- **Structured dispatch** — dispatches between commander and agents must go through the `dispatch_to({to, message})` tool call (a structured channel); `@` in prose is not recognized as a dispatch signal (the user's `@` is still text-recognized — user UX unchanged)
-- **Deferred wake-up** — a `dispatch_to` call only stages; the recipient worker is woken up only after the commander's current turn finishes, preventing premature execution
-- **Turn-based safety stop** — the runaway-loop guard counts turns (`MAX_WORKER_TURNS=100`), not wall-clock time. A slow LLM that's making progress isn't a runaway loop
-
-### Meta-cognition: `meta/` + self-managed skills
-
-Each agent maintains two kinds of self-knowledge in its own directory, written by the agent itself:
-
-- **`meta/COMPETENCE.md`** — what I'm good at / not good at
-- **`meta/LEARNING_STRATEGIES.md`** — methods that have worked for me
-
-After each task, the agent reflects and updates these two files; on the next task, `meta/` is fed in as part of the system prompt, **so experience actually shapes the next run**.
-
-The other evolution path is the `skill_manage` tool: an agent can crystallize "this is how I solved X" into a skill that **only belongs to itself** (a private SkillStore, independent of the global skill library). The next similar task calls it directly — no need to re-derive it every time.

-## Why Orkas?
+## What can you build with it?
 
-Orkas isn't a single personal AI assistant that follows you across messaging channels, and isn't a hosted SaaS — it's a desktop app where you assemble a team of specialized agents and command them through one chat.
+- **Automate recurring reports & market research** — a specialist agent gathers, summarizes, and ships a weekly report.
+- **Turn a product spec into dev tasks** — the Commander breaks a PRD into tasks and dispatches them across agents.
+- **Chat with your documents & run local data analysis** — drop files in, keep the data on your machine.
+- **Go beyond code — video, slides, and more** — the Commander drives open-source tools like HyperFrames and hands off to CLI coding agents (Claude Code, Codex, OpenCode, Cline) and other local agents, so one chat produces code, research, video, and slide decks.

+## How Orkas compares
+
+| Tool | What it is | How Orkas differs |
 | --- | --- | --- |
-| **OpenClaw** | A personal AI assistant you run on your own devices, reaching you across the messaging channels you already use. Single-user, always-on, channel-native. | Orkas is a desktop multi-agent client: instead of one assistant on every channel, you build a team of specialized agents and direct them through a single desktop chat — visibility-sliced collaboration, a shared `plan.md`, and per-agent self-evolution. OpenClaw also plugs in as an Orkas CLI backend, so an Orkas agent can hand work off to your OpenClaw. |
-| **Hermes-Agent** | Nous Research's self-improving personal AI agent — a TUI plus multi-channel gateway, with a built-in learning loop, scheduled automations, and the ability to run on a cheap VPS or serverless infra. | Orkas is desktop-GUI and team-shaped: a commander LLM dispatches a *team* of agents in parallel or in series through one chat; each agent has its own private skill library and meta-cognition, and the entire stack runs locally on your machine. Hermes-Agent is also pluggable as an Orkas CLI backend. |
-| **Cloud agent platforms** (SaaS multi-agent orchestrators) | Server-hosted; conversations, files, and API keys live on the vendor's infrastructure. | Orkas is local-first: conversations, files, API keys, knowledge bases, custom agents / skills / memory all stay on your machine. Model API calls go straight from your machine to the provider — never through Orkas servers, and never archived. |
+| **LangChain** | A developer framework/library for building LLM apps and agents — code-first, embedded in your own Python/JS app. | Orkas is a local-first multi-agent desktop app you direct through chat, not by writing orchestration code. Data and keys stay local by default. |
+| **CrewAI** | A Python framework for orchestrating role-playing autonomous agents — you define crews and agents in code. | Orkas brings multi-agent orchestration into a desktop app, with **local-first storage** and per-agent self-evolution built in. |
+| **Cloud agent platforms** (SaaS orchestrators) | Server-hosted; conversations, files, and API keys live on the vendor's infrastructure. | Orkas is **local-first**: everything stays on your machine, and model API calls go straight to the provider — never archived by Orkas. |
+| **OpenClaw** | A single always-on personal assistant reaching you across messaging channels. | Orkas gives you a team rather than one assistant: the Commander coordinates specialist agents from one desktop chat, and OpenClaw plugs in as an Orkas CLI backend. |
+| **Hermes-Agent** | Nous Research's self-improving personal agent (TUI + multi-channel gateway). | Orkas is a local-first multi-agent desktop app, with per-agent private skills and meta-cognition — and Hermes-Agent plugs in as an Orkas CLI backend. |
 
-**Orkas is for you if**: you want a *team* of agents, not a single personal assistant; you want a desktop GUI with file drop-in and visual agent management; and you want your data, keys, and agents on your own disk rather than in a vendor cloud.

+## FAQ
+
+**What is Orkas?**
+Orkas is an open-source, local-first multi-agent desktop app. A super-powered Commander plans your goal and coordinates specialist agents to complete it together — nine of them ship with the app. Not a single chatbot, not a code framework, not a hosted SaaS.
+
+**Is Orkas a local LLM?**
+No. Orkas runs on your machine but calls the models you choose through your own API keys (or a local model endpoint). It orchestrates agents and tools — it is not itself a model.
+
+**Can I use local models like Ollama or LM Studio?**
+Yes. Add them under **Settings → AI Providers → Custom (OpenAI-compatible)** and point the base URL at your local endpoint. You can run one agent on a local model and another on a hosted one in the same chat.
+
+**Where are my API keys and data stored?**
+On your disk. Conversations, files, knowledge bases, agents, and keys stay local; model calls go straight from your machine to the provider and are never proxied or archived by Orkas.
+
+**Does Orkas work offline?**
+The app is fully offline-capable — only the model calls need network. Point agents at a local model endpoint and you can run without the cloud.
+
+**Do I need an Orkas account?**
+The packaged desktop app asks you to sign in when you first launch it. The source build in this repository has no account layer at all — it boots straight into the app. Either way your model keys are your own and stay on your machine.
+
+**Can Orkas drive Claude Code and other CLI coding agents?**
+Yes. Beyond its own Commander and specialist agents, Orkas can drive external CLI coding agents — Claude Code, Codex, OpenCode, Cline — as local subprocesses, and onboard open-source projects like HyperFrames, all directed from the same chat.
+
+**How is Orkas different from Claude Desktop / CrewAI / LangChain?**
+Claude Desktop is a single assistant; CrewAI and LangChain are code-first frameworks. Orkas is a local-first multi-agent desktop app: the Commander coordinates specialist agents, keeps data and keys local, and gives each agent its own private skills and memory. See the [full comparisons](https://orkas.ai/compare/orkas-vs-langchain?source=gh-orkas).
+
+**Which platforms does Orkas support?**
+macOS (Apple Silicon and Intel) and Windows 10+ have packaged installers. Linux runs from source today — same app, no installer yet. The source build needs Node 20+ and Python 3.
+
+**Is Orkas free and open source?**
+Yes — the app is MIT licensed and free to use. Bring your own model keys and you pay only your model providers; Orkas never takes a cut. Optionally, the desktop app also offers a built-in **Orkas model** for people who don't want to manage API keys — that one is billed by Orkas in credits (membership or credit packs). It is entirely opt-in, and every other feature works on your own keys. [Pricing →](https://orkas.ai/pricing/?source=gh-orkas)

+
+---
+
+## How it works (core design)
+
+> Full design and hard constraints → [`CLAUDE.md`](./CLAUDE.md)
+
+### Three dispatch verbs, and the rule for choosing between them
+
+The Commander is the only actor holding dispatch tools — workers and agents have none. Which verb it picks decides who the user hears from and whether the Commander stays in the loop:
+
+| Verb | User sees the agent's reply | Result returns to the Commander | Commander's turn |
+| --- | --- | --- | --- |
+| `hand_off_to({ to, message })` | yes | no | ends — the agent's reply stands as the answer |
+| `dispatch_to({ to, message })` | yes | yes | continues with a named next step |
+| `run_worker({ to, task })` | no — private input | yes | continues |
+
+The Commander has to name its concrete next action *before* it may choose `dispatch_to`; if all that remains is restating the agent's reply, the rule forces `hand_off_to`. That single constraint is what stops a multi-agent chat from ending in a redundant re-summary of what you already read. Emitting several `run_worker` calls in one response runs them concurrently.
+
+### One runtime, bounded fan-out
+
+Each conversation has a single FIFO runtime, and top-level turns run through it serially; parallelism happens *inside* a turn as nested in-process dispatch ([`bus.ts`](./src/main/features/group_chat/bus.ts)). Two separate semaphores bound it — `globalSlots = 10` across all users, and `dispatchSlots = 4` for nested dispatches (`ORKAS_MAX_DISPATCH_CONCURRENCY`).
+
+Nested runs deliberately skip `globalSlots`: the parent turn already holds a slot, so a nested acquire would deadlock as parent-waits-on-child. That shortcut is safe only because dispatch tools belong to the Commander alone, so the semaphore is never acquired re-entrantly — the deadlock is ruled out by construction, not by a timeout.
+
+### Context budget: derived from the model, not a fixed number
+
+Every compaction threshold is derived from the model in use, so one policy fits a 32K window and a 1M one alike ([`context-budget.ts`](./src/core-agent/src/agent/context-budget.ts)):
+
+```
+usableInput   = contextWindow − maxOutputTokens − safety
+messageBudget = max(usableInput × 0.2, usableInput − systemPrompt − toolDefs)
+```
+
+Every trigger is a share of `messageBudget` — 0.3 for the in-turn layer, 0.2 for cross-turn history, 0.1 for one round's inline tool results — and everything else derives from its trigger, so the shares are the only tunable surface. They sum to well under 1, leaving room for injected runtime state and for the growth that happens between a trigger firing and its summary landing. The `max` is a fuse: when a large tool set would otherwise swallow the window, messages keep a floor share instead of computing a negative budget.
+
+A run compacts as many times as it needs to — there is deliberately **no ceiling on successful passes**. What is bounded is wasted work instead: a fingerprint check refuses to compact identical state twice, a minimum-savings threshold rejects passes that would free too little, and three consecutive failures stop LLM-backed compaction.
+
+Summarization loses detail, so what an agent must not forget is kept as structure rather than prose. A workspace ledger of files written, files read, and commands run survives compaction ([`workspace-state.ts`](./src/core-agent/src/agent/workspace-state.ts)), and a spin detector — two or more compactions plus 75% of the tool budget consumed — nudges the agent once to re-anchor on that ledger instead of re-deriving work it just summarized away.
+
+### Memory: hybrid retrieval over a local index
+
+A knowledge base is a SQLite index built on your machine — FTS5 for full text, stored vectors for similarity ([`memory/`](./src/core-agent/src/memory)). Documents are chunked at 512 lines with 64 lines of overlap; a query runs both ways and the two ranked lists merge by reciprocal rank fusion, weighted 0.7 vector to 0.3 keyword. Agents reach it through `memory_search` and `memory_read`, over stored documents and past sessions alike.
+
+Embeddings are computed **on device** by a bundled ONNX model (`bge-small-zh-v1.5`, ~95 MB, fetched once during install), so indexing a knowledge base sends nothing anywhere. Cloud embedding providers — OpenAI, Gemini, Voyage, Mistral — are available if you prefer them.
+
+### Four independent runaway guards
+
+- **Turn ceiling** — `MAX_WORKER_TURNS = 100` counts turns, not wall-clock time, so a slow-but-progressing model isn't killed.
+- **Per-turn tool rounds** — Commander 120, named agent 100, ephemeral worker the schema default ([`actor-budgets.ts`](./src/main/features/group_chat/actor-budgets.ts)), pinned by unit tests so they can't silently drift.
+- **`loop_detection`** — nudges the model after N consecutive identical or near-duplicate tool calls.
+- **Tool-idle watchdog** — for turns that stall rather than loop.
+
+### Self-evolution: signal-triggered, not after every task
+
+Each agent keeps `meta/COMPETENCE.md` (what it is and isn't good at) and `meta/LEARNING_STRATEGIES.md` (methods that have worked for it), both fed back into its system prompt on the next run.
+
+Reflection is not a fixed counter. A weighted trigger scores six signals — `error_recovery`, `user_correction`, `complexity`, `known_weakness`, `weakness_succeeded`, `skill_ineffective` — and reviews only when the total clears a threshold, generating the review prompt from whichever signal dominated ([`metacognition.ts`](./src/core-agent/src/evolution/metacognition.ts)). Through `skill_manage` an agent can also crystallize "how I solved X" into a **private** `SKILL.md` that it can use from the next turn on.

+macOS 和 Windows 提供安装包。Linux 目前需从源码运行 —— 见 [快速开始](#快速开始)。
 
-### 群聊：可见性切片 + 单一调度原语
-
-一个对话里同时坐着指挥官、N 个智能体、用户，但每个智能体看到的对话**不是同一份**。
-
-- **可见性切片**——主对话写一份全量 jsonl；每个智能体在自己的 `visibility/<aid>.jsonl` 里只拿到一个切片：`from==自己 ∨ to∋自己 ∨ mentions∋自己`。worker 只读自己的切片，**不读全量主对话**——既省 token，也防止私有上下文跨智能体泄漏
-- **单一调度原语**——所有派活（指挥官的 `dispatch_to`、用户文本里的 `@`、计划拆分出的步骤）都汇到同一个 `enqueue` 原语，没有并行调度路径。新增派活方式必须经过它，避免散出"谁能唤醒谁"的混乱
-- **共享 plan**——多智能体协作的进度由指挥官写在一份 `plan.md` 里，所有成员都看得到当前推进到哪一步
-
-### 智能体调度：结构化通道，不靠消息里的 @
-
-LLM 容易把 `@` 当 markdown 装饰打出来——在消息里识别 `@` 派活会反复误触发。所以：
-
-- **结构化派活**——指挥官与智能体之间的派活必须走 `dispatch_to({to, message})` 工具调用，是个结构化通道；散文里的 `@` 系统不识别为派活信号（用户的 `@` 仍走文本识别，UX 不变）
-- **延迟唤醒**——一次 `dispatch_to` 调用只 stage，收件人 worker 在指挥官当前 turn 完整收尾后才被唤醒，防止抢跑
-- **轮次维度兜底**——死循环防护按轮次（`MAX_WORKER_TURNS=100`）而不是按时间。LLM 慢但有产出 ≠ 死循环
-
-### 元认知自演进：meta/ + 自管技能
-
-每个智能体在自己的目录里维护两类"自我认知"，由智能体自己写：
-
-- **`meta/COMPETENCE.md`**——我擅长 / 不擅长什么
-- **`meta/LEARNING_STRATEGIES.md`**——我用过哪些有效的方法
-
-任务跑完后，由智能体自我反思并更新这两份文件；下次接到任务时，meta 会作为 system prompt 的一部分喂给它，**让经验真正影响下一次的行为**。
-
-另一条进化路径是 `skill_manage` 工具：智能体可以把"这次解决 X 的招式"固化成一个**只属于自己**的技能（私有 SkillStore，独立于全局技能库）。下次同类任务直接调用，不用每次重推。

+## 常见问题（FAQ）
+
+**Orkas 是什么？**
+Orkas 是一个开源、本地优先的多智能体桌面应用。一个超强指挥官规划你的目标，并协调多个专业智能体共同完成 —— 其中 9 个随应用内置。不是单个聊天机器人，不是代码框架，也不是托管 SaaS。
+
+**Orkas 是本地大模型吗？**
+不是。Orkas 运行在你的机器上，但通过你自己的 API key（或本地模型端点）调用你选择的模型。它编排智能体与工具，本身不是模型。
+
+**能用 Ollama、LM Studio 这类本地模型吗？**
+可以。在 **设置 → AI 服务商 → 自定义（OpenAI 兼容）** 中添加，把 base URL 指向你的本地端点即可。同一个对话里，一个智能体用本地模型、另一个用云端模型也没问题。
+
+**我的 API key 和数据存在哪里？**
+在你的硬盘上。对话、文件、知识库、智能体和 key 都留在本地；模型调用从你的机器直连服务商，绝不被 Orkas 代理或归档。
+
+**Orkas 能离线用吗？**
+应用本身可完全离线运行 —— 只有模型调用需要网络。把智能体指向本地模型端点，就能脱离云端运行。
+
+**需要注册 Orkas 账号吗？**
+安装包版本在首次启动时会要求登录。本仓库的源码版本完全没有账号模块，启动后直接进入应用。两种方式下，模型 key 都是你自己的，并且留在本机。
+
+**Orkas 能驱动 Claude Code 等 CLI 编程智能体吗？**
+能。除了自己的指挥官与专业智能体，Orkas 还能把外部 CLI 编程智能体（Claude Code、Codex、OpenCode、Cline）作为本地子进程驱动，并接入 HyperFrames 等开源项目，全部在同一个对话里指挥。
+
+**Orkas 和 Claude Desktop / CrewAI / LangChain 有什么不同？**
+Claude Desktop 是单个助理；CrewAI 和 LangChain 是代码优先的框架。Orkas 是一个本地优先的多智能体桌面应用：指挥官协调多个专业智能体，数据与 key 留在本地，每个智能体拥有私有技能与记忆。见[逐项对比](https://orkas.ai/compare/orkas-vs-langchain?source=gh-orkas)。
+
+**支持哪些平台？**
+macOS（Apple 芯片与 Intel）和 Windows 10+ 提供安装包。Linux 目前从源码运行 —— 功能相同，只是还没有安装包。源码运行需要 Node 20+ 与 Python 3。
+
+**Orkas 免费且开源吗？**
+是的 —— 应用本身 MIT 许可证、免费使用。自带模型 key 时，你只需为你的模型服务商付费，Orkas 不抽成。此外，桌面版还提供一个可选的内置 **Orkas 模型**，供不想自己配置 key 的用户使用 —— 这部分由 Orkas 按 credits 计费（会员或 credits 包）。它完全可选，其余所有功能用你自己的 key 即可。[价格 →](https://orkas.ai/pricing/?source=gh-orkas)

+## 工作原理（核心设计）
+
+> 完整设计与硬约束 → [`CLAUDE.md`](./CLAUDE.md)
+
+### 三个派发动词，以及选哪个的规则
+
+指挥官是唯一持有派发工具的角色 —— worker 和智能体都没有。选哪个动词，决定了用户听谁说话、以及指挥官是否留在回合里：
+
+| 动词 | 用户看得到智能体的回复 | 结果回传给指挥官 | 指挥官的回合 |
+| --- | --- | --- | --- |
+| `hand_off_to({ to, message })` | 是 | 否 | 结束 —— 智能体的回复本身就是答案 |
+| `dispatch_to({ to, message })` | 是 | 是 | 继续执行一个已命名的下一步 |
+| `run_worker({ to, task })` | 否 —— 作为私有输入 | 是 | 继续 |
+
+指挥官必须**先**说出自己具体的下一步动作，才可以选 `dispatch_to`；如果剩下的事只是复述智能体的回复，规则就强制它改用 `hand_off_to`。正是这一条约束，让多智能体对话不会以"把你刚读过的内容再总结一遍"收尾。在同一次回复里发出多个 `run_worker` 调用，它们会并发执行。
+
+### 单一运行时，有界扇出
+
+每个对话只有一个 FIFO 运行时，顶层回合串行通过它；并行发生在回合**内部**，以进程内嵌套派发的形式（[`bus.ts`](./src/main/features/group_chat/bus.ts)）。两个独立的信号量为它设界 —— 跨所有用户的 `globalSlots = 10`，以及用于嵌套派发的 `dispatchSlots = 4`（可用 `ORKAS_MAX_DISPATCH_CONCURRENCY` 覆盖）。
+
+嵌套运行刻意跳过 `globalSlots`：父回合已经占着一个槽位，嵌套获取会造成"父等子"的死锁。这个捷径之所以安全，只因为派发工具专属于指挥官，信号量不可能被重入获取 —— 死锁是被构造排除的，而不是靠超时兜底。
+
+### 上下文预算：由模型推导，而不是写死一个数
+
+每个压缩阈值都由当前使用的模型推导而来，因此同一套策略既适配 32K 窗口，也适配 1M 窗口（[`context-budget.ts`](./src/core-agent/src/agent/context-budget.ts)）：
+
+```
+usableInput   = 上下文窗口 − 最大输出 token − 安全余量
+messageBudget = max(usableInput × 0.2, usableInput − 系统提示 − 工具定义)
+```
+
+每个触发阈值都是 `messageBudget` 的一个份额 —— 回合内层 0.3、跨回合历史 0.2、单轮内联工具结果 0.1 —— 其余参数都由触发阈值派生，因此这几个份额是唯一的可调面。它们的总和远小于 1，留出的余量用于回灌的运行时状态，以及"触发发生到摘要落地"之间仍在继续的增长。那个 `max` 是保险丝：当工具集大到会吃掉整个窗口时，消息仍保有一个底线份额，而不是算出一个负预算。
+
+一次运行需要压缩多少次就压缩多少次 —— **成功压缩的次数刻意不设上限**。真正设界的是无效功：指纹校验拒绝对同一状态重复压缩，最小收益阈值拒绝那些释放太少的压缩，连续三次失败则停止 LLM 压缩。
+
+摘要必然丢细节，所以智能体绝不能忘的东西不交给散文承载。一份记录"写过哪些文件、读过哪些文件、跑过哪些命令"的工作台账会以结构形式挺过压缩（[`workspace-state.ts`](./src/core-agent/src/agent/workspace-state.ts)）；另有一个空转检测 —— 压缩两次以上且工具预算已消耗 75% —— 会提醒智能体一次，让它回到台账重新锚定，而不是把刚被摘要掉的工作再推导一遍。
+
+### 记忆：本地索引上的混合检索
+
+资料库是一份构建在你本机的 SQLite 索引 —— 用 FTS5 做全文、用存储的向量做相似度（[`memory/`](./src/core-agent/src/memory)）。文档按 512 行切块、块间重叠 64 行；一次查询两路并发，两个排序结果用 reciprocal rank fusion 融合，权重为向量 0.7、关键词 0.3。智能体通过 `memory_search` 与 `memory_read` 访问它，检索范围同时覆盖存入的文档和历史会话。
+
+嵌入向量**在本机计算**，由随包的 ONNX 模型完成（`bge-small-zh-v1.5`，约 95 MB，安装时下载一次），因此建立资料库索引不会把任何内容发出去。如果你更愿意用云端嵌入服务，OpenAI、Gemini、Voyage、Mistral 也都支持。
+
+### 四道互相独立的失控保护
+
+- **轮次上限** —— `MAX_WORKER_TURNS = 100` 计的是回合数而非墙钟时间，因此一个慢但在推进的模型不会被误杀。
+- **每回合工具轮数** —— 指挥官 120、具名智能体 100、临时 worker 用 schema 默认值（[`actor-budgets.ts`](./src/main/features/group_chat/actor-budgets.ts)），由单元测试钉死，不会悄悄漂移。
+- **`loop_detection`** —— 连续 N 次相同或近似重复的工具调用后提醒模型。
+- **工具空闲看门狗** —— 针对卡住而非打转的回合。
+
+### 自我进化：由信号触发，而非每次任务都做
+
+每个智能体维护 `meta/COMPETENCE.md`（我擅长什么 / 不擅长什么）和 `meta/LEARNING_STRATEGIES.md`（对我有效的方法），两者都会在下一次运行时回喂进它的系统提示。
+
+复盘不是固定计数器。一个加权触发器为六个信号打分 —— `error_recovery`、`user_correction`、`complexity`、`known_weakness`、`weakness_succeeded`、`skill_ineffective` —— 只有总分越过阈值才触发复盘，并依据占主导的那个信号生成复盘提示（[`metacognition.ts`](./src/core-agent/src/evolution/metacognition.ts)）。通过 `skill_manage`，智能体还能把"我是如何解决 X 的"结晶成一份**私有** `SKILL.md`，从下一回合起即可使用。

+ * orkas-bridge — stdio MCP server an external CLI agent (claude code /
+ * codex) spawns to reach the Orkas environment (plan §D).
+ *
+ * Spawned via the per-run MCP config that `features/local_agents/bridge.ts`
+ * writes; never started by hand. Everything it can do is brokered:
+ *
+ *   orkas_list_skills / orkas_read_skill     → bridge socket → main process
+ *   orkas_run_skill                          → bridge allow-list → run-skill.cjs
+ *   orkas_list_connector_tools /
+ *   orkas_call_connector_tool                → bridge socket (permission-gated host-side)
+ *   library                                  → bridge socket
+ *   chat_history                             → bridge socket (current chat only)
+ *   orkas_handoff_to_commander               → bridge socket (run-local signal)
+ *
+ * The host injects ORKAS_BRIDGE_CAPABILITIES. A category outside that
+ * allowlist is not registered in MCP discovery at all.
+ *
+ * Env (injected by bridge.ts into the MCP server config or parent CLI env):
+ *   ORKAS_BRIDGE_ENV_FILE — optional 0600 JSON env file containing the
+ *                         secret-bearing values below
+ *   ORKAS_BRIDGE_SOCKET — unix socket / named pipe back to the Orkas main
+ *                         process for this run
+ *   ORKAS_BRIDGE_TOKEN  — per-run auth token (dies with the run)
+ *   ORKAS_BRIDGE_CAPABILITIES — comma-separated run capability allowlist
+ *   ORKAS_PC_DIR        — PC root for SDK + run-skill resolution
+ *   ORKAS_NODE / ORKAS_BUNDLED_NODE / ORKAS_WORKSPACE_ROOT / ORKAS_UID
+ *                       — the stock background Node + standard skill-sandbox set
+ *
+ * CommonJS + absolute-path requires (the process cwd is the CLI agent's
+ * project dir, not PC) — same conventions as run-skill.cjs.

+# Task notifications regression
+
+## Scope
+
+Native notifications are an attention layer for tasks that reach a terminal
+state while Orkas is still running but no app window is focused. The app-level
+preference and the operating-system permission are independent authorities:
+the checkbox stores the user's choice, while the recovery row explains when the
+system prevents visible delivery. Notifications do not change task execution,
+window-close, or process-exit behavior.
+
+Unread task replies are a separate in-app attention layer. Their red dots are
+sidebar-only: next to the Tasks/Projects section labels, the owning project,
+and each unread task row. No project header, project tab, or content task list
+may mirror those dots.
+
+## Scenario matrix
+
+| User goal / scenario | Starting state and variation | Expected observable outcome | Consequential failure and recovery | Layer and independent oracle | Current risk or coverage gap |
+| --- | --- | --- | --- | --- | --- |
+| Keep the notification choice across restarts | Preference missing, enabled, or disabled | Missing defaults to enabled; an explicit choice survives a full relaunch | A stale checkbox misleads the user about delivery; reopening Settings must recover from disk | Config unit plus Electron E2E reads the persisted preference after relaunch | Renderer-only checks cannot prove real IPC and persistence wiring |
+| Enable notifications while OS permission is refreshing | Saved preference is off, a focus/load permission read is pending, and the user enables notifications | The new preference remains enabled while a denied OS result still shows the actionable recovery row | Treating the whole read as stale can overwrite the user choice or hide recovery | Renderer race harness independently controls read/write completion and observes the final checkbox and warning | Preference and permission have different authorities and completion order |
+| Recover from a failed write | The setter rejects, returns a mismatched value, or throws | The checkbox rolls back to the actual/previous value, is re-enabled, and can be retried | False success leaves notification delivery different from the UI | Renderer harness injects each failure and observes final state and bounded local logs | Optimistic UI must not become the persisted source of truth |
+| Recover from blocked system presentation | App preference enabled; permission denied or badge-only; settings route available or unavailable | Warning appears only while blocked, the button appears only when actionable, and focus return refreshes status | The app claims delivery is enabled without a recovery path | Renderer permission-state harness plus platform manual matrix | Real OS presentation state is platform-owned and cannot be fully simulated portably |
+| Notice a finished background task | Completed, failed, waiting for input, or cancelled; app focused or backgrounded | Supported background terminal states create one generic native notification; focused/cancelled states do not | Missing notification hides completed work; a false notification distracts the user | Main feature tests observe the native-notification adapter and prohibited calls | Actual banners require platform manual verification |
+
+## Automated coverage
+
+- `test/e2e/settings_e2e_persistence.spec.ts`
+  - changes the real Settings checkbox through renderer, preload, Main IPC, and
+    persisted configuration;
+  - verifies the value after a full Electron relaunch.
+- `test/renderer/settings-task-notifications.test.ts`
+  - proves the enabling-write versus permission-read race in both completion
+    orders;
+  - rolls back rejected, mismatched, and thrown writes without disabling retry;
+  - shows denied and badge-only recovery only while the app preference is on;
+  - refreshes permission after returning from System Settings;
+  - verifies all shipped locales provide badge-only recovery copy.
+- `test/main/features/config.test.ts`
+  - proves default enabled behavior plus explicit disable/re-enable persistence.
+- `test/main/features/notification_permissions.test.ts`
+  - covers macOS authorization/presentation normalization, Windows setting
+    mapping, and platform settings URLs.
+- `test/main/features/task_notifications.test.ts`
+  - covers focused-window, unsupported-platform, cancelled, and inactive-user
+    suppression; generic localized copy; click routing; handle retention; and
+    synchronous/asynchronous delivery failure cleanup.
+- `test/renderer/task-notification-navigation.test.ts`
+  - holds cold-start clicks until initialization, rejects malformed navigation,
+    and opens the originating conversation.
+
+## Manual matrix
+
+1. Open Settings → General → Task notifications.
+   - A new user sees the checkbox enabled.
+   - Turning it off suppresses completed, failed, and waiting-for-input system
+     notifications without changing task execution or in-app results.
+   - Turning it on restores notifications without restarting.
+2. Relaunch after each checkbox state.
+   - Settings shows the last saved state.
+3. Disable Orkas notifications in macOS or Windows settings while the app
+   checkbox remains enabled, then return to Settings.
+   - A permission warning appears below the checkbox.
+   - **Open system settings** is present only when the platform exposes a route.
+   - Enabling permission and returning to Orkas hides the stale warning.
+   - Turning the app checkbox off hides the warning without changing OS state.
+4. On macOS, leave only the app-icon badge enabled and disable banners/alerts
+   plus Notification Center.
+   - Settings reports that visible presentation is disabled.
+   - Restoring banners/alerts or Notification Center clears the warning after
+     Orkas regains focus.
+5. Start a task and keep the Orkas window focused until completion.
+   - No native notification appears.
+6. Start a task, then minimize Orkas or focus another application.
+   - Exactly one generic notification appears after the entire task finishes.
+   - It contains no prompt, conversation title, attachment name, generated
+     content, path, or other private user data.
+7. Click the notification.
+   - A minimized or hidden window is restored and focused.
+   - The originating conversation opens and its latest history loads.
+8. Stop a running task.
+   - No native completion notification appears.
+
+## Synchronization protection
+
+The source synchronization rules declare five required shared regions for this
+capability: configuration persistence, Main IPC preference handling, Settings
+DOM, renderer state handling, and permission-warning styles. Every region is
+checked on every synchronization run even when its surrounding multi-feature
+file has an accepted whole-file adaptation. Region drift or a missing/ambiguous
+anchor must fail closed, repair from the commercial source, and select the
+owning focused tests above.
+
+This regression matrix is itself an explicitly inventoried test support file.
+That exact declaration overrides the source repository's broad private-docs
+filter; unrelated commercial process and design documents remain excluded.
+
+## Residual gap
+
+Automated tests cannot portably force every real macOS/Windows notification
+presentation configuration. Release verification must retain manual steps 3–7
+and inspect application/runtime logs for delivery rejection, fallback, timeout,
+or an unexpected error before reporting the platform path as verified.

+description_zh: VideoStudio 的 COMPOSE 视觉自检清单 - 在展示 HTML 预览前，由作者自己完整检查首帧、每镜中点与收束帧，汇总一次可执行修复；不向宿主提交任何审查结果。
+description_en: Advisory visual checklist for VideoStudio COMPOSE. The author reviews the first frame, every scene midpoint, and the payoff frame before exposing the HTML preview, batching actionable fixes; nothing is submitted to the host.
+---
+
+# composition-design-review
+
+Apply this checklist yourself after a successful `composition.snapshot`, before the preview is shown. It is advisory: nothing is submitted to the host, no operation records a verdict, and no gate waits on it — the host publishes the contact sheet with the passing snapshot. It is a design QA layer for your own authoring, not a renderer, line router, or generic video craft checklist.
+
+Do not open a new user Gate. Native preflight/inspect/sampled-frame QA runs before this pass; a passing snapshot attaches the full-color contact sheet directly as model-visible evidence. Review every frame in that attached complete index, without reopening the sheet through generic `read_files`, and open at full scale only the frame-0 cover, frames named by QA findings, and frames whose sheet cell shows risk (dense or doubtful text, suspected overlap or blankness). Do not stop after the first defect. Collect all concrete visible blockers across the full frame set, make one batched localized repair to `manifest.art_direction` or affected HTML, and re-run inspect + snapshot; then re-check the complete new frame set.
+
+## Activation
+
+Apply the checklist whenever snapshot evidence exists, and give it extra weight when:
+
+- The approved brief is brand, product, promo, launch, version-update, portfolio, or other design-led COMPOSE work.
+- `project/composition/composition-manifest.json::art_direction.style_source` is present.
+- Sampled frames show a visible design risk that deterministic QA cannot judge, such as a weak first frame, flat hierarchy, repeated scene grammar, or motion that hides the message.
+
+Do not run this review for non-COMPOSE edit/TTS/clip-selection work. Do not repeat the full pass after the draft renders — post-draft QA is native and render-specific.
+
+## Review Inputs
+
+Read only the relevant artifacts:
+
+- `project/composition/composition-manifest.json`, especially `art_direction` and the affected canonical scene
+- Every composition-local image/video in `art_direction.references`, including declared roles, reproduce/edit/guide intent, preserve/may-change boundaries, target scenes, and layout/temporal anchors
+- `project/composition/narration-map.json` as read-only evidence when detailed narration-line alignment matters
+- `project/composition/qa/inspect.json`, or `project/render/draft-report.json` only for fallback review
+- For preview review, the snapshot result's `contact_sheet` covering every `frame_paths` item: first frame, every scene midpoint, and payoff/closing frame. Open individual paths where the activation rule above points — cover, QA-named frames, risky cells.
+- For fallback review, sampled evidence frames from the draft report: `contact_sheet`, `frame_paths`, first frame, one mid-frame per scene, and payoff/closing frame
+- The approved script only when a finding depends on message intent
+
+## Findings Rubric
+
+Tag each finding as `blocker`, `fix`, or `polish`.
+
+Blockers must identify a specific scene/frame, the visible evidence, and the smallest repair. A finding is not a blocker just because the design could be more distinctive, or because inspect reported a visual advisory that does not break the approved promise.
+
+Blockers:
+
+- First frame is blank, unreadable, or fails the dedicated cover contract: approved promise, dominant hero, and at least two recognizable signals of the actual video content.
+- Text is unreadable in the supplied evidence frame, hides the approved promise/CTA, or materially blocks comprehension because of size, safe-zone, overlap, occlusion, or contrast.
+- The draft report's `contract_html` step says approved scene copy, canvas, assets, or runtime dependencies do not match the model-authored HTML.
+- Visual language contradicts an explicit style source or ignores required brand tokens.
+- A reference image or video loses a declared preserve axis, changes something outside `may_change`, violates layout/temporal anchors, misses a requested edit, or is scored below `reference_fidelity.verification.minimum_score`.
+- The piece reads as a slideshow when the approved promise was motion graphics.
+- Motion hides the message, distracts from the focal point, or breaks narration timing.
+- A protected logo/asset/layout was copied without ownership or permission.
+
+Fix:
+
+- First frame is truthful and readable but its topic signals are too generic or weak to work as a strong cover.
+- Text has a visible safe-zone, size, overlap, occlusion, or contrast advisory, but the main message remains readable and the draft is useful for Gate D review.
+- Repeated layout, transition, or card pattern three or more times in a row.
+- Palette uses extra chromatic colors beyond the contract.
+- Type hierarchy is flat or labels feel like UI residue instead of video graphics.
+- English titles, body copy, captions, subtitles, or CTAs are forced to all caps, or two or more English text roles in one scene use all caps. Restore the approved natural casing and use scale, weight, width, color, or spacing for hierarchy. Existing all caps may remain only when the exact casing appears in approved user copy or an external brand/source and is limited to one short metadata label, acronym, or code; a model-authored art direction or style rationale is not an exception.
+- Scene density is too high for phone viewing.
+- Style-source adaptation is vague: it borrows mood words but no concrete tokens.
+- Reference comparison is vague or based on provenance instead of the declared media intent, roles, protected attributes, allowed changes, and scene/time anchors.
+
+Polish:
+
+- Easing, stagger, spacing, shadow, stroke, or texture could better support the tone.
+- A stronger thumbnail frame or payoff hold would improve memorability.
+- A minor token mismatch that does not hurt comprehension.
+
+## Repair Preference
+
+Fix the highest-level canonical artifact that caused the issue:
+
+1. `composition-manifest.json::art_direction` when the thesis, style source, tokens, layout budget, or per-scene visual plan is wrong.
+2. `composition-manifest.json` when canonical scene timing or source-shot mapping is wrong; use the normal `stage-compose` reconciliation path after changing protected fields.
+3. `index.html` for visual hierarchy, typography, layout, motion, asset, or scene variation fixes.
+
+Use `narration-map.json` only to diagnose detailed narration-line alignment. Do not edit it from design review; hand alignment findings back to `stage-compose`, which owns narration materialization and reconciliation.
+
+Do not solve design problems by only nudging pixels. If the issue is "too generic", change the signature device or scene grammar. If the issue is "too dense", remove or split content.
+
+## Output Format
+
+Summarize your pass in a few bullets before continuing:
+
+- `blockers`: all concrete locations + evidence + repair, not only the first finding
+- `fixes`: concrete location + repair applied
+- `polish`: optional notes that travel with the Gate D note
+
+Then repair and re-run inspect + snapshot, or — when the frames read well — hand readiness to `gate-control`. There is no score to compute and nothing to submit: quality is judged by what is visibly broken in a specific frame, never by a number.

+description_zh: VideoStudio 的参考媒体与设计系统输入层——统一处理参考图片、参考视频、品牌规范、网站截图和设计说明，按复刻/编辑/借鉴意图写入可执行的画面与时序约束。
+description_en: Reference-media and design-system input layer for VideoStudio. Treat reference images, reference videos, screenshots, brand guides, and design notes uniformly, compiling reproduce/edit/guide intent into executable spatial and temporal constraints.
+---
+
+# design-system-importer
+
+Use this when COMPOSE or an AUTO compose segment has any external reference media or style source: a reference image, reference video, `DESIGN.md`, brand guide, screenshot, existing website, design notes, or an explicit named visual direction.
+
+Do not use it for ordinary editing, TTS, shot generation, or clip selection. Do not introduce a new user Gate. The output is an internal style extraction that feeds `project/composition/composition-manifest.json::art_direction` and the model-authored `project/composition/index.html`.
+
+Do not use it for vague adjectives like "modern", "clean", "premium", "dynamic", or "more polished" when no source is named. In those cases, let `frontend-design` choose the aesthetic thesis directly from the video brief.
+
+## Reference Intent Before Input Technique
+
+For every supplied image or video, first classify what the user wants from it. Explicit user requirements always override defaults; infer only when the user is silent:
+
+- `reproduce`: preserve the declared content, identity, composition, structure, style, motion, timing, or audio axes.
+- `edit`: use the media as the original, protect all declared unaffected axes, and change only `may_change`.
+- `guide`: borrow only the declared roles and do not imply exact fidelity. This is the safe default for an otherwise unspecified reference.
+
+Record `intent_basis:"user"` for an explicit requirement and `intent_basis:"inferred"` for a fallback. A request to change the supplied original implies edit; an explicit restore/recreate/match request implies reproduce; otherwise default to guide. Mixed instructions keep their operational intent while the user's exact protected and changeable axes remain authoritative. This classification is independent of origin. A screenshot, exported frame, camera photo, generated image, HTML capture, design-tool export, uploaded MP4, or generated video receives the same contract when the requested intent and roles are the same.
+
+Copy every exact inspected media file into `project/composition/assets/references/` before authoring and record that composition-local path. Do not rely on a chat thumbnail, stale temporary path, or prose description after the source has been supplied.
+
+## Source Access Is An Optimization, Not A Different Contract
+
+If the user owns reusable source code, vectors, layers, or assets, use them when that is the safest way to satisfy the same reference contract. If only pixels are available, derive the same spatial/temporal anchors from pixels. Availability of HTML, an ImageStudio project, or another authoring format must not change the requested intent, roles, fidelity floor, or review rubric.
+
+Adapt style; do not copy logos, protected assets, proprietary text, or trademarked UI one-to-one.
+Keep extraction small enough to fit inside the manifest art direction. Do not load or recreate an entire external design system.
+
+## Extract Compact Tokens
+
+Write a `style_source` object under `art_direction` in `project/composition/composition-manifest.json`:
+
+```json
+{
+  "art_direction": {
+    "style_source": {
+      "source_type": "brand_system | design_notes | reference_media | existing_product | named_reference",
+      "source_basis": "file path, user note, or inspected artifact",
+      "adaptation_boundary": "what may be borrowed vs what must not be copied",
+      "confidence": "high | medium | low",
+      "fidelity_mode": "exact | close | adapt"
+    }
+  }
+}
+```
+
+Then normalize the source into sibling fields in `manifest.art_direction` that model-authored HTML/CSS/SVG can consume:
+
+- `color_tokens`: background, surface, text, muted, primary accent, optional secondary accent, plus intended contrast relationship.
+- `typography_tokens`: display, body, data/label, caption roles; scale and weight intent; avoid relying on fonts that are not available.
+- `shape_tokens`: radius, stroke, shadow, divider, border, and density.
+- `layout_language`: grid, editorial, cinematic, dashboard, diagrammatic, poster, product-demo, or another concrete grammar.
+- `motion_language`: entrance, transition, emphasis, data-build, and exit patterns; keep it compatible with GSAP timeline seeking.
+- `asset_rules`: what images/icons/marks are allowed, need replacement, or must be avoided.
+- `do_not_copy`: logos, exact layouts, trademarked copy, screenshots, or protected illustrations unless the user owns them.
+
+Keep the imported style small. If more than 6 chromatic colors or 3 font roles are needed, summarize the conflict and pick the smallest faithful subset.
+
+## Write An Executable Media Contract
+
+For every concrete image or video, write `art_direction.references`; then write the shared `art_direction.reference_fidelity` policy:
+
+```json
+{
+  "references": [{
+    "id": "reference-1",
+    "media_type": "image | video",
+    "path": "assets/references/reference.mp4",
+    "intent": "reproduce | edit | guide",
+    "roles": ["content", "identity", "composition", "structure", "style", "motion", "timing", "audio"],
+    "required": true,
+    "preserve": ["subject identity", "camera path", "beat timing"],
+    "may_change": ["copy"],
+    "target_scene_ids": ["scene-1"],
+    "temporal_anchors": [
+      { "source_start_sec": 0, "source_end_sec": 3.2, "target_scene_id": "scene-1" }
+    ]
+  }],
+  "reference_fidelity": {
+    "mode": "exact | close | adapt",
+    "preserve": ["composition", "identity", "motion"],
+    "may_change": ["copy", "aspect-safe reflow"],
+    "layout_anchors": [{ "id": "hero", "role": "hero", "bounds": { "x": 0.08, "y": 0.12, "width": 0.5, "height": 0.7 } }],
+    "verification": { "minimum_score": 85, "compare_frames": ["first-frame", "scene-1-mid"] }
+  }
+}
+```
+
+Choose the mode from user intent, not convenience:
+
+- `exact`: the user asks to reproduce/continue the supplied design. Preserve at least three named axes; minimum score must be at least 85.
+- `close`: keep its recognizable system and spatial grammar while adapting content/aspect/motion.
+- `adapt`: borrow selected tokens or a visual principle; do not claim pixel fidelity.
+
+Map image composition/structure into normalized layout anchors, not only adjectives. For a video used to reproduce, edit, control motion, or control timing, map source time ranges to target scenes with temporal anchors. The model must be able to answer what stays, what changes, where it appears, and when each preserved beat happens.
+
+## Map To Video
+
+Web and brand systems are not videos. Convert them for motion:
+
+- First frame: choose the style's strongest thumbnail-friendly signal.
+- Safe zones: enlarge type and spacing beyond web density.
+- Scene variation: turn repeated web sections into distinct beats.
+- Motion: make the brand grammar move with purpose; do not animate every component.
+- Captions: keep ordinary subtitles in `tracks.captions.lines`, not in the style system.
+
+## Output
+
+After extraction, `manifest.art_direction` must state:
+
+- What source was used.
+- Which tokens were adopted.
+- Which tokens were deliberately simplified.
+- Which elements must not be copied.
+- What visual signature will make the video feel related to the reference without becoming a clone.
+- Which image/video reference intent and roles, preserve/may-change rules, target scenes, layout/temporal anchors, and scored verification floor apply.

+description_zh: VideoStudio 的 HTML/动态图形审美层——在 stage-compose 写 manifest.art_direction 与 index.html 前，用主题世界、字体、配色、布局签名、动效克制和反模板检查，把普通可渲染页面提升为有明确视觉观点的视频画面。
+description_en: Aesthetic direction for VideoStudio HTML and motion-graphics compositions. Use before stage-compose writes manifest.art_direction and index.html to choose a subject-specific visual point of view, type, palette, layout signature, restrained motion, and anti-template checks.
+---
+
+# frontend-design
+
+Use this as the design-lead layer for VideoStudio COMPOSE work. It shapes `project/composition/composition-manifest.json::art_direction` and the model-authored HTML/SVG motion graphics in `index.html`.
+
+This skill does not pick the video production line, replace `video-craft`, or relax Orkas renderer constraints. If there is a conflict, renderer determinism, safe zones, legibility, audio ownership, and user-approved creative direction win.
+
+## Generation references
+
+Read only the references required by the current composition:
+
+- [HTML generation playbook](references/html-generation-playbook.md) — read before coding every non-trivial COMPOSE deliverable for the private art-direction pass, frame-composition rules, and opening/resolved-state authoring pattern.
+- [Visual primitives](references/visual-primitives.md) — read when selecting reusable CSS/SVG composition primitives and scene grammar.
+- [Worked compositions](references/worked-compositions.md) — read when examples are needed to turn subject matter into a cohesive visual system without copying a fixed template.
+
+These references improve the initial generation. They do not create a new artifact, user gate, or approval step. Keep the art-direction pass internal and record only the decisions needed to make the manifest art direction executable.
+
+## Design Thesis
+
+Before writing HTML, choose a compact visual thesis:
+
+- `subject_world`: the real materials, artifacts, interface metaphors, gestures, environment, or culture of the topic.
+- `audience`: who must understand this at phone size and what they already know.
+- `one_job`: what this video frame sequence must make clear.
+- `tone`: one or two precise words that shape type, color, spacing, and motion.
+- `signature_device`: one memorable visual move that belongs to this brief.
+- `aesthetic_risk`: one justified choice that avoids generic output without hurting readability.
+
+Keep the thesis specific. "Modern tech style" is not a thesis. "Battery-lab oscilloscope traces become the progress line" is.
+
+## HyperFrames-style authoring discipline
+
+This is a creative discipline, not a fixed renderer or template catalog. VideoStudio still uses model-authored HTML, but the model must author like a motion designer instead of jumping straight from storyboard text to scattered SVG nodes.
+
+### Visual identity hard gate
+
+Do not start `index.html` until the composition has a usable visual identity in `manifest.art_direction`:
+
+- `aesthetic.subject_world`
+- `aesthetic.one_job`
+- `aesthetic.signature_device`
+- `aesthetic.aesthetic_risk`
+- `aesthetic.anti_template_check` (or legacy `anti_template`)
+- `cover` with first-scene id, approved headline, two or more content signals, hero visual, composition strategy, and `frame_time_sec:0`
+- role-based `typography_tokens`
+- baseline `color_tokens`
+- `visual_direction` with a design tradition, lazy-default rejections, video-scale rule, depth-layer rule, motion-verb rule, and rhythm pattern
+- a scene-level plan with `hero_visual`, `depth_layers`, `opening_state`, and `resolved_state`
+- for every concrete reference image or video, executable `references` + `reference_fidelity` contracts from `design-system-importer`, based on reproduce/edit/guide intent rather than origin
+
+If the first concrete visual move is a generic grid, circles connected by lines, a centered title card, emoji-as-icon, or a web-dashboard layout, the visual identity is not ready. Revise the art direction first; do not compensate with more glows or animation.
+
+### VisualDirectionV1
+
+For non-trivial COMPOSE work, write a compact `visual_direction` object inside `manifest.art_direction`. It is the front-loaded aesthetic director for HTML authoring; it is not a template and not a user gate.
+
+Required fields:
+
+- `visual_tradition`: a real design tradition, designer, art movement, or cultural reference that controls composition behavior. Examples: `Swiss Pulse / Josef Müller-Brockmann precision grid`, `Data Drift / Refik Anadol data field`, `Velvet Standard / Vignelli restraint`, `Deconstructed / Neville Brody rupture`, `Maximalist Type / Paula Scher scale`. Avoid empty labels such as "modern tech", "premium", or "cinematic" by themselves.
+- `composition_behavior`: how frames should be arranged and how the eye should travel: grid-locked data, research atlas, editorial archive, full-bleed object, kinetic type wall, product surface, map/flow, or diagram build.
+- `lazy_defaults_rejected`: the first generic design move rejected and the brief-specific replacement. Question purple/blue neon gradients, black neon circles, centered equal-weight layouts, identical cards, decorative emoji/icons, tiny badges, default web dashboards, and pure black/white.
+- `video_scale`: the scale floor for this canvas. For 1920x1080, default to headline 72-140px, body 28-42px, labels 18-26px, borders 2-4px, safe padding 60-140px, and decorative opacity 12-25%.
+- `depth_layer_rule`: how every scene will maintain background atmosphere, midground content, and foreground accents/metadata with topic-derived materials.
+- `motion_verb_rule`: the verbs primary elements are allowed to use. Every meaningful element needs a verb such as draws, locks, counts up, slams, drifts, fractures, reveals, or resolves.
+- `typography_register`: the communication roles for display, body, data/label, caption, and any expressive font. Do not pair two similar sans-serifs; use extreme weight/scale contrast and video-readable type.
+- `rhythm_pattern`: the scene rhythm before HTML, such as `hook-build-HOLD-surge-resolve`, `drift-build-PEAK-drift-resolve`, or `fast-fast-SLOW-fast-hold`.
+
+Example:
+
+```json
+{
+  "visual_direction": {
+    "visual_tradition": "Swiss Pulse precision grid + Data Drift AI atmosphere",
+    "composition_behavior": "research atlas: huge years anchor a coordinate grid while model/paper fragments lock into position",
+    "lazy_defaults_rejected": "reject glowing circles on a thin timeline; replace with paper fragments, parameter contours, and data-field coordinates",
+    "video_scale": "1920x1080: headline 88-132px, body 30-38px, labels 20-26px, borders 2-4px, safe padding 96-140px, atmospheric opacity 12-22%",
+    "depth_layer_rule": "BG token field/grid/grain, MG timeline and model artifacts, FG large year + metadata ticks",
+    "motion_verb_rule": "timeline draws, years stamp, nodes lock, token fields drift, paper fragments slide/resolve",
+    "typography_register": "large tabular years as display voice, concise Chinese labels as body, monospace metadata for data",
+    "rhythm_pattern": "hook-build-HOLD-surge-resolve"
+  }
+}
+```
+
+### Resolved frame before motion
+
+For each scene, build the fully readable resolved frame first in static HTML/CSS/SVG. This is the frame where the scene's message, hierarchy, and hero visual are clearest.
+
+Then add GSAP entrances and meaningful reveals from that static state. The resolved frame must be what renders at t=0: entrances animate FROM a visible state, never from `opacity: 0` — not on the scene, and not on the one element that carries its message. Every composition is frame-0 sampled — including each AUTO segment — so a scene that fades in captures blank and fails QA before anyone sees it. The CSS/SVG resolved layout is the source of truth; the timeline describes how the viewer arrives there. Do not design a scene by placing elements at their animated start state and hoping the tween lands in a good composition.
+
+For every non-trivial scene, internally check before writing tweens:
+
+- What is the one dominant visual object at the resolved frame?
+- Does meaningful visual material occupy the safe canvas, or is it a small cluster in empty space?
+- Which topic-derived background, midground hero, and foreground annotation layers are visible?
+- What changes between opening and resolved state beyond a container fade?
+- Which element carries continuity from the prior scene?
+
+### Preview critique before draft
+
+When the COMPOSE HTML Preview Gate is required, treat the contact sheet as the design checkpoint. If the preview shows a scene that looks like a low-effort slide, a generic diagram, or text labels substituting for the promised visual, repair the manifest art direction or affected HTML before moving to mp4 draft. This is a localized HTML-preview correction, not an open-ended final-video rerender loop.
+
+## Avoid Template Gravity
+
+Reject choices that could fit almost any brief:
+
+- Purple/blue neon gradients, glass panels, generic bento cards, floating UI cards, decorative blobs, and stock SaaS dashboards unless the subject truly calls for them.
+- Numbered markers, timelines, terminal windows, blueprint grids, or newspaper rules when the content is not actually sequential, technical, architectural, or editorial.
+- A palette made from one hue family with lighter/darker variations only.
+- Long labels in circles, tiny badges, dense microcopy, or walls of text doing the visual's job.
+- Motion everywhere. Spend motion on the one thing the viewer must notice.
+- Decorative emoji/icons as the primary graphic language. Use topic-specific SVG marks, diagrams, data forms, object silhouettes, or typographic systems instead unless the user explicitly asked for playful emoji language.
+
+If the first design idea feels like a reusable demo template, revise the thesis before coding.
+
+## HTML Aesthetic Floor
+
+Treat the composition as designed video frames, not a web page inside a video canvas.
+
+- Start from a frame grammar: full-bleed visual system, split focal/annotation, diagram build, editorial title wall, data mark, product surface, map/flow, or quote/argument. Pick one because it matches the brief, then vary it across scenes.
+- Avoid default centered-card scenes, generic gradient backgrounds, floating bento panels, pill badges, and dashboard fragments unless the subject itself is an app/dashboard and the UI is the point.
+- The first frame must be a composed thumbnail: readable promise, subject-specific visual signal, and no blank/slow intro. Never tween from `opacity: 0` at 0s — not the opening scene, and not any single element that carries its promise: the `data-role="title"`, the `data-cover-hero`, a declared signal. Hiding only the title still leaves frame 0 without the promise and returns `HOOK_PROMISE_NOT_VISIBLE`; the rule binds to the elements that carry the cover, not only to their container. Motion may begin at 0s, but the exact still frame at 0s must already say what the video is about.
+- Treat that first frame as a dedicated cover design. It needs one dominant hero plus at least two visible content signals from the actual video; a generic branded/title treatment that could front an unrelated topic does not pass. Bind it to `art_direction.cover`, not only to an aesthetic paragraph. Mark the topic-specific dominant visual with `data-role="visual" data-cover-hero`; do not put that marker on a generic background or decorative accent. Native QA reads the declared signals off the visible frame-0 copy, so a signal you actually put on screen counts; add `data-cover-signal="<content_signals value>"` when the signal is carried by an element with no readable text of its own. Signals must say something the headline does not — a `content_signals` entry that only restates the headline is reported as `headline_only` and does not count. The headline itself may run across consecutive `data-role="title"` lines. Native QA reports rendered hooks and hero bounds as advisories, not blockers: design the cover to this standard because it is what makes the video open well, not because a checker will bounce you.
+- Build every designed frame in three semantic depth layers: a topic-derived background field, a dominant midground message/diagram, and foreground accents or metadata. Do not add arbitrary decoration; every layer should reinforce subject, hierarchy, scale, direction, or continuity.
+- Use video scale, not web scale: for 1920x1080, headlines usually need 72-140px, body/supporting text 28-42px, labels 18-26px, borders 2-4px, safe padding 60-140px, and atmospheric decoratives 12-25% opacity. Anything under 24px or under 10% opacity needs a reason.
+- Use a visible hierarchy system: one dominant focal element, one supporting focal/text zone, and optional labels. A designed explainer's meaningful visual material should usually occupy most of the safe canvas rather than clustering in one corner. If a scene needs more than two text zones, split the beat or convert detail into a diagram.
+- Give every scene an `opening_state`, `explanation_state`, and `resolved_state`. The resolved state must be visibly more informative than the opening state, and the viewer should get a clean hold before the next scene.
+- Give every meaningful element a motion verb before writing GSAP. If the author cannot say whether a path draws, a year stamps, a number counts up, a card locks, or a texture drifts, the element is not yet designed.
+- Carry one subject-specific visual object across scene boundaries when the story benefits from continuity: a signal, path, document fragment, product surface, token stream, map route, or data mark. Transform it instead of resetting every scene to a fresh title slide.
+- Prefer custom SVG marks for the signature device: paths, meters, grids, maps, traces, connectors, data shapes, or object silhouettes. Do not rely on rows of identical cards to create visual interest.
+- For product or brand work, make the product/brand signal large in the first viewport/frame. Do not hide it as a tiny nav/logo equivalent.
+- Use texture, depth, and color sparingly but deliberately. A good frame should still read in grayscale; accent colors should explain hierarchy, data meaning, brand, or transition state.
+- Add semantic hooks in HTML: `data-scene-id` on each scene root and `data-role="title|body|label|caption|visual"` on important elements. Native QA uses them to attach findings to a scene and role; missing hooks remain advisory and should not trigger a rerender by themselves.
+
+## Manifest Art-direction Fields
+
+Add an `aesthetic` object under `art_direction` in `project/composition/composition-manifest.json`:
+
+```json
+{
+  "art_direction": {
+    "aesthetic": {
+      "subject_world": "what the visual language borrows from",
+      "audience": "who it is for",
+      "one_job": "the frame sequence's job",
+      "tone": ["precise", "brief"],
+      "signature_device": "one remembered visual behavior",
+      "aesthetic_risk": "the deliberate non-default choice",
+      "anti_template_check": "what was rejected as too generic"
+    }
+  }
+}
+```
+
+The rest of `manifest.art_direction` must make the thesis executable:
+
+- `visual_direction`: the `VisualDirectionV1` object: design tradition, composition behavior, rejected lazy defaults, video scale, depth-layer rule, motion-verb rule, typography register, and rhythm pattern.
+- `cover`: the frame-0 communication contract: first canonical `scene_id`, approved `headline`, concrete `content_signals`, `hero_visual`, thumbnail `composition_strategy`, and `frame_time_sec:0`.
+- `references` + `reference_fidelity`: when concrete media exists, its image/video type, reproduce/edit/guide intent, user/inferred intent basis, roles, local path, preserve/may-change axes, target scenes, layout/temporal anchors, and scored verification floor supplied by `design-system-importer`. Explicit user constraints override inferred defaults.
+- `provenance`: keep visual-source records under `art_direction.provenance`. For authored visuals, set `art_direction.provenance.visuals` to `self-authored HTML/CSS/SVG`; never put provenance at the manifest root. Any external replacement asset must record its source and license here.
+- `typography_tokens`: role-based, not just sizes. Include display, body, data/label, and caption roles when needed.
+- `color_tokens`: named baseline values with rationale. Include neutrals, primary accent, and any purposeful supporting accents needed for brand, hierarchy, data meaning, or scene variation.
+- `layout_boxes`: describe visual hierarchy, not only coordinates. Name the focal zone, supporting zone, depth layers, and intended meaningful canvas coverage.
+- `motion_budget`: state what carries meaning, what stays still, and how each transition maps to the story.
+- `scene_variation`: prevent three near-identical card/title scenes in a row.
+- Each designed `art_direction.scenes[]` entry should compactly name `id`, `scene_world`, `hero_visual`, `composition`, `depth_layers`, `motion_verbs`, `opening_state`, `resolved_state`, `continuity_in`, `continuity_out`, and any `primitive_refs` selected from the generation references. Keep these fields inside the canonical manifest; do not create another planning artifact.
+
+## HTML Direction
+
+When writing `index.html`:
+
+- Complete the private art-direction pass from the [HTML generation playbook](references/html-generation-playbook.md) immediately before coding. Decide the dominant visual, spatial tension, depth layers, opening/resolved states, and continuity behavior for every scene; do not output this as a new user gate.
+- When a reusable CSS/SVG scene grammar improves the brief, select and adapt it from [Visual primitives](references/visual-primitives.md). These are ingredients, not templates: change geometry, scale, rhythm, and content so the result belongs to the brief.
+- Derive the main CSS variables from `manifest.art_direction`; keep extra chromatic colors intentional and named enough to audit. Do not flatten the design or recolor the whole video only to reduce a static palette count.
+- Let one element carry personality: a custom progress line, typographic reveal, diagram grammar, texture, data mark, or transition family. Keep surrounding elements quiet.
+- Use type as design material: contrast display/body roles, make title/body hierarchy unmistakable, and keep labels large enough for the video-craft floor.
+- Preserve the authored casing of approved English copy. Use sentence case or natural title case for titles and sentence case for body copy, captions, subtitles, and CTAs. Existing all caps may remain only when that exact casing appears in approved user copy or an external brand/source, and then only for one short metadata label, eyebrow, acronym, or code. A model-authored art direction, design tradition, typography register, or generic tech/editorial mood is never permission to convert copy to all caps. Never apply `text-transform: uppercase` through a broad selector or use all caps for multi-line copy; if a title, body, caption, subtitle, or CTA is all caps, or two English text roles in one scene read as all caps, restore the approved casing and revise the hierarchy with family, width, weight, scale, color, or spacing instead. Casing findings are advisory and never block a preview — except changing the casing of copy the user approved, which is a signed-intent violation and does block.
+- Do not default every composition to Arial/Helvetica with only size changes. Use available local or deterministic system font stacks deliberately, create contrast through family, width, weight, scale, color, spacing, or tracking while preserving approved casing, and vendor any required font inside `assets/`; never fetch a remote font at render time.
+- Use structural marks only when they encode meaning: steps for sequences, coordinates for maps, ticks for time, nodes for relationships, brackets for comparison.
+- Prefer SVG for diagrams, paths, meters, masks, charts, and signature geometry; keep prose and captions as real HTML text.
+- Default to SVG/static held states first. Use GSAP only when a timed reveal, transition, or emphasis genuinely improves comprehension; animate SVG groups or a few containers instead of many HTML cards.
+- For vertical video, design for platform UI: keep essential text away from the bottom action area and make the first frame readable as a thumbnail.
+- Respect `prefers-reduced-motion` in CSS where practical, but drive render-critical animation through the paused GSAP timeline.
+
+## Build Loop
+
+1. Draft the thesis, dedicated cover, any concrete reference-fidelity contract, and the rest of `manifest.art_direction`.
+2. Self-critique the art direction: name the most generic choice and replace it.
+3. Run the internal pre-code art-direction pass: choose `VisualDirectionV1`, scene grammar, hero visual, three depth layers, motion verbs, typography register, rhythm pattern, opening/resolved states, and cross-scene continuity. Keep it inside the generation turn; no new user confirmation.
+4. Write HTML/SVG from the manifest art direction using adapted visual primitives and worked examples as references, not fixed templates.
+5. Run the draft QA command. If `draft_disposition.blocking_error_count` or structural/video/audio QA fails, repair `manifest.art_direction` or the canonical scene structure first; do not only nudge CSS numbers. Missing preview-required art direction is a blocking manifest error, not a cosmetic note: complete the aesthetic thesis, dedicated cover, VisualDirectionV1, motion budget, scene variation budget, per-scene depth layers, and per-scene motion verbs before preview or draft. Treat visual/readability findings as draft notes unless they make the approved message unreadable. Low-cost native warnings for contrast, safe area, density, repeated layout, or palette narrowness are feedback for the next localized edit; they do not by themselves justify expensive rerender loops.
+6. For preview, judge the returned keyframe contact sheet rather than only frame 0. Score whether frame 0 communicates the actual video as a cover. When reference images exist, compare spatial anchors and declared axes side-by-side. When reference videos exist, compare the declared source time ranges against their target scene frames and motion/timing intent. Score the requested reproduce/edit/guide outcome, never the reference's origin. After a rendered draft, use `design_review_inputs` plus the first frame, scene mids, and payoff frame for: clear focal point, subject-specific visual language, readable type, reference fidelity, and motion with purpose.
+
+## Output Standard
+
+When reporting a COMPOSE draft or blocker, include the short design direction used: thesis, signature device, and any inspect/craft issue that forced a design change.

+# HTML generation playbook
+
+Use this during the initial COMPOSE generation, after the brief/storyboard is approved and before writing `index.html`. This is an internal authorship pass, not a user gate and not a new required project file.
+
+## Private pre-code art direction
+
+For the whole piece, decide five things before coding:
+
+1. **Material world** — list the real artifacts, surfaces, marks, diagrams, interfaces, documents, objects, or physical behaviors that belong to the topic. Prefer those over generic circles and lines.
+2. **Recurring carrier** — choose one visual object that can move through the story: signal, rule, token stream, document strip, route, waveform, product surface, cursor, scale, or data mark.
+3. **Type behavior** — choose how display, supporting copy, labels, and data differ through family, width, weight, scale, color, spacing, or tracking while preserving approved casing.
+4. **Spatial rhythm** — alternate where the dominant mass lives. A sequence can move left-heavy → full-field → right-heavy → centered payoff; it should not reset to the same top-left title layout each time.
+5. **Motion logic** — decide what information is established, explained, and resolved. Motion must change meaning or state, not merely prove that animation exists.
+
+For every scene, internally answer:
+
+- What single visual object explains this beat without narration?
+- Where does the largest visual mass sit, and how much of the safe canvas does it occupy?
+- What are the background, midground, and foreground layers?
+- What is already visible on the first frame of the scene?
+- What new understanding exists in the resolved frame?
+- What enters from the previous scene and what leaves for the next one?
+- Which primitive or custom SVG construction will implement it?
+
+Put compact answers in the existing design contract scene fields when they help HTML execution. Do not create a separate approval artifact.
+
+Before coding the first scene, resolve the dedicated cover contract separately: approved headline, dominant hero, at least two concrete signals of the video's real content, and a composition that still communicates at thumbnail size. Frame 0 is the exported cover, so it cannot be a generic title treatment or an incomplete tween state.
+
+When reference media exists, place each copied image or sampled video anchor beside its planned target frame. Convert declared layout anchors into explicit HTML/CSS/SVG regions and map video temporal anchors to their target scene/timeline positions before styling details. If safe owned layers or assets happen to be available, they may help execute the same contract, but they do not change the reproduce/edit/guide intent. Write motion around preserved geometry and timing; do not let animation become an excuse for drift.
+
+## Compose a frame, not a page
+
+A good video frame remains intentional when paused:
+
+- Use asymmetric tension, scale contrast, edge anchoring, cropping, overlap, or a strong full-field structure. Do not center every object inside generous web-page whitespace.
+- Let meaningful material occupy the canvas. Empty space is useful only when it creates direction, suspense, scale, or emphasis.
+- Use three semantic depth layers. Background structure should belong to the subject; midground carries the main message; foreground annotations, ticks, fragments, or masks create scale and finish.
+- Build one dominant focal point and one supporting focal point. Tiny labels scattered around a small diagram do not create hierarchy.
+- Prefer a few large shapes and readable annotations over many small cards. At phone size, labels must remain legible and the hero graphic must still read as a silhouette.
+- Treat exact words, dates, numbers, and CTA copy as real HTML. Use SVG for geometry, relationships, paths, masks, charts, and spatial systems.
+
+## Opening, explanation, resolved
+
+Every scene needs three authored states:
+
+1. **Opening** — the premise and visual identity are already visible. The first scene must never be a blank canvas waiting for a fade.
+2. **Explanation** — structure, comparison, connection, or causality becomes visible in a controlled sequence.
+3. **Resolved** — the completed idea holds long enough to read and should be visibly different from the opening state.
+
+Author the resolved state first in HTML/CSS/SVG, then decide which parts begin muted, clipped, offset, or incomplete. Avoid building a scene whose only change is container opacity.
+
+For the first scene:
+
+```js
+// The opening composition is visible at t=0. Animate supporting structure,
+// not the whole scene from a blank frame.
+tl.set('#s01', { opacity: 1 }, 0)
+  .fromTo('#s01 .signal',
+    { strokeDashoffset: 720 },
+    { strokeDashoffset: 0, duration: 1.2, ease: 'power2.out' }, 0)
+  .fromTo('#s01 .annotation',
+    { opacity: 0.25, y: 18 },
+    { opacity: 1, y: 0, duration: 0.65, stagger: 0.08 }, 0.25);
+```
+
+For later scenes, a hard cut, wipe, carried object, or short crossfade may reveal the next scene at its start. Do not spend the first second of every scene fading an empty layout into view.
+
+## Scene variation without random style changes
+
+Keep typography, palette, stroke character, corner treatment, and the recurring carrier consistent. Vary two or more of these per scene:
+
+- dominant mass position;
+- full-field versus split composition;
+- visual grammar: document, path, network, comparison, scale, object, quote;
+- camera/framing: macro crop, overview, detail, centered payoff;
+- motion behavior: draw, reveal, accumulate, transform, converge;
+- relationship between text and visual: integrated, adjacent, overprinted, annotated.
+
+Variation is structural, not a new palette or unrelated visual style every few seconds.
+
+## Generation-time anti-patterns
+
+Replace these before coding:
+
+- `top-left headline + small diagram below` repeated across the sequence;
+- a pure-color background with only one thin SVG group;
+- four words placed around a circle as a substitute for an explanation;
+- multiple diagonal lines without scale, anchors, values, or change over time;
+- universal Arial/Helvetica with no meaningful role contrast;
+- all scene roots fading from opacity zero;
+- a final frame that is identical to the prior scene midpoint;
+- arbitrary decorative particles, blobs, cards, grids, or glows unrelated to the topic.
+
+## Initial-generation checklist
+
+Before saving `index.html`, verify from the source itself:
+
+- frame 0 contains the promise and a subject-specific visual signal;
+- frame 0 satisfies every `art_direction.cover.content_signals` item and reads as the actual video's cover;
+- reference images and videos satisfy their reproduce/edit/guide intent, protected axes, allowed changes, and layout/temporal anchors;
+- every scene has background, midground, and foreground intent;
+- each scene has a large, recognizable hero visual;
+- the spatial sequence varies without losing the shared visual system;
+- opening and resolved states differ meaningfully;
+- one carrier or motif creates continuity across the piece;
+- typography roles differ beyond font size;
+- SVG structure encodes real content rather than generic decoration;
+- no remote runtime dependency is required;
+- animation is deterministic and registered on the paused GSAP timeline.

+# Video visual primitives
+
+These are adaptable ingredients for model-authored HTML, not fixed templates. Select only the primitives justified by the brief, then change geometry, scale, copy, density, and motion to fit the subject.
+
+## 1. Composition chassis
+
+Use a shared token chassis so scenes feel related while their layouts vary:
+
+```css
+:root {
+  --bg: #081018;
+  --ink: #f3f0e8;
+  --muted: #9ca8b4;
+  --accent: #ffb000;
+  --support: #55d6c2;
+  --danger: #ff665c;
+  --safe-x: 112px;
+  --safe-y: 92px;
+  --hairline: 2px;
+}
+
+* { box-sizing: border-box; }
+html, body { width: 1920px; height: 1080px; overflow: hidden; margin: 0; }
+body {
+  color: var(--ink);
+  background: var(--bg);
+  font-family: "Avenir Next", "Helvetica Neue", Arial, sans-serif;
+}
+.scene {
+  position: absolute;
+  inset: 0;
+  overflow: hidden;
+  isolation: isolate;
+}
+.safe { position: absolute; inset: var(--safe-y) var(--safe-x); }
+.display {
+  font-size: clamp(76px, 6.1vw, 118px);
+  line-height: .9;
+  font-weight: 760;
+  letter-spacing: -.055em;
+}
+.supporting {
+  max-width: 720px;
+  font-size: 42px;
+  line-height: 1.16;
+  color: var(--muted);
+}
+.label {
+  font-size: 38px;
+  line-height: 1;
+  font-weight: 650;
+  letter-spacing: .06em;
+}
+```
+
+Derive tokens from the design contract. Do not paste this palette into unrelated work.
+Preserve the authored case. Existing all caps may remain only when the exact casing appears in approved user copy or an external brand/source and is limited to one short metadata label, acronym, or code. A model-authored art direction or generic tech/editorial mood is not permission to introduce it, and it is never a broad-selector treatment for titles, body copy, captions, or CTAs.
+
+## 2. Topic-derived background field
+
+A background field establishes material and depth without becoming a dashboard:
+
+```css
+.field::before {
+  content: "";
+  position: absolute;
+  inset: -8%;
+  z-index: -2;
+  background:
+    linear-gradient(90deg, color-mix(in srgb, var(--ink) 7%, transparent) 1px, transparent 1px),
+    linear-gradient(color-mix(in srgb, var(--ink) 5%, transparent) 1px, transparent 1px);
+  background-size: 96px 96px;
+  mask-image: linear-gradient(90deg, transparent, #000 18%, #000 82%, transparent);
+}
+.field::after {
+  content: "";
+  position: absolute;
+  width: 820px;
+  height: 820px;
+  right: -240px;
+  top: 80px;
+  border-radius: 50%;
+  background: radial-gradient(circle, color-mix(in srgb, var(--accent) 18%, transparent), transparent 68%);
+  filter: blur(24px);
+  z-index: -1;
+}
+```
+
+Adapt the field to the topic: manuscript rules, map coordinates, spectral bands, film grain, product geometry, waveform lanes, token cells, or measured laboratory ticks. A generic grid is not automatically appropriate.
+
+## 3. Asymmetric split
+
+Use for an argument plus one substantial visual:
+
+```css
+.split {
+  display: grid;
+  grid-template-columns: minmax(0, .78fr) minmax(0, 1.22fr);
+  gap: 88px;
+  align-items: center;
+  height: 100%;
+}
+.split[data-mass="left"] { grid-template-columns: 1.25fr .75fr; }
+.split__visual { min-height: 700px; position: relative; }
+```
+
+The visual zone should contain a real diagram, object, image crop, chart, or structural typographic composition. Do not place a small icon in a large empty column.
+
+## 4. Editorial title wall
+
+Use an oversized, edge-anchored title plus subject evidence—not a centered hero card:
+
+```css
+.title-wall .display {
+  position: absolute;
+  left: var(--safe-x);
+  bottom: 138px;
+  width: 78%;
+  font-size: 142px;
+}
+.title-wall .ghost {
+  position: absolute;
+  right: 70px;
+  top: 22px;
+  font-size: 330px;
+  line-height: 1;
+  font-weight: 800;
+  color: color-mix(in srgb, var(--ink) 5%, transparent);
+  letter-spacing: -.08em;
+}
+.title-wall .evidence {
+  position: absolute;
+  right: var(--safe-x);
+  top: 118px;
+  width: 560px;
+  min-height: 260px;
+  border-top: var(--hairline) solid var(--accent);
+}
+```
+
+`evidence` can be a paper excerpt, product crop, map, data mark, waveform, or diagram fragment that proves the subject immediately.
+
+## 5. SVG signal carrier
+
+Use one path to carry continuity across scenes. Author the resolved path in SVG and animate `stroke-dashoffset`:
+
+```html
+<svg class="carrier" viewBox="0 0 1200 620" aria-hidden="true">
+  <path class="carrier__guide" d="M40 480 C260 80 430 560 650 220 S980 120 1160 300" />
+  <path class="carrier__signal" pathLength="1"
+        d="M40 480 C260 80 430 560 650 220 S980 120 1160 300" />
+  <g class="carrier__marks">
+    <circle cx="40" cy="480" r="10" />
+    <circle cx="650" cy="220" r="10" />
+    <circle cx="1160" cy="300" r="10" />
+  </g>
+</svg>
+```
+
+```css
+.carrier__guide { fill: none; stroke: color-mix(in srgb, var(--ink) 13%, transparent); stroke-width: 2; }
+.carrier__signal { fill: none; stroke: var(--accent); stroke-width: 7; stroke-linecap: round; stroke-dasharray: 1; stroke-dashoffset: 1; }
+.carrier__marks circle { fill: var(--bg); stroke: var(--ink); stroke-width: 3; }
+```
+
+Change the path into a route, reading order, waveform, parameter curve, product flow, or narrative thread. It must encode meaning.
+
+## 6. Measured comparison field
+
+Comparisons need scale and anchors, not unlabeled diagonal lines:
+
+```html
+<svg viewBox="0 0 1100 640" class="measure" aria-hidden="true">
+  <g class="measure__grid">
+    <path d="M120 60V560H1040" />
+    <path d="M120 435H1040M120 310H1040M120 185H1040" />
+  </g>
+  <g class="measure__bars">
+    <rect x="210" y="430" width="150" height="130" rx="4" />
+    <rect x="470" y="300" width="150" height="260" rx="4" />
+    <rect x="730" y="105" width="150" height="455" rx="4" />
+  </g>
+</svg>
+```
+
+Place exact values and labels as nearby HTML text. Animate bars, range fills, or paths from a common baseline, then hold the completed comparison.
+
+## 7. Document-to-diagram transformation
+
+For research, history, policy, or technical explanations:
+
+- Start from a large cropped document fragment or typographic excerpt.
+- Highlight one phrase, equation, heading, or date.
+- Extend rules/connectors from that evidence into the explanatory diagram.
+- Preserve one fragment as foreground context while the diagram resolves.
+
+This is stronger than replacing the source with a generic network graphic.
+
+## 8. Convergence field
+
+For multimodal, systems, ecosystems, or synthesis:
+
+- Give each input its own material behavior, not just a word around a circle.
+- Text can arrive as token rows; audio as a measured waveform; image as crop tiles; code as aligned syntax bands.
+- Let inputs bend, mask, or recompose into one shared output object.
+- Resolve into a new state that visibly contains evidence of all inputs.
+
+## 9. Deterministic motion recipes
+
+Use a small number of semantic groups:
+
+```js
+// Establish -> explain -> resolve -> hold.
+tl.set(scene, { opacity: 1 }, start)
+  .fromTo(`${id} .structure`, { opacity: .35 }, { opacity: 1, duration: .55 }, start)
+  .fromTo(`${id} .build`, { strokeDashoffset: 1 }, { strokeDashoffset: 0, duration: 1.25 }, start + .18)
+  .fromTo(`${id} .result`, { opacity: 0, y: 22 }, { opacity: 1, y: 0, duration: .65 }, start + 1.05);
+```
+
+Use explicit timeline positions. CSS animations, timers, random particles, and runtime network calls are not render-safe.
+
+## Primitive selection guide
+
+- Research/history: editorial title wall + document-to-diagram + signal carrier.
+- Data/scale: measured comparison + full-field data mark + annotated path.
+- Product/feature: product surface + asymmetric split + cursor/route carrier.
+- Systems/process: map/flow + convergence field + state transformation.
+- Quote/argument: oversized type + evidence fragment + rule/annotation system.
+- Abstract concept: choose a concrete physical behavior first—accumulation, compression, branching, collision, alignment, or convergence—then build custom SVG around it.
+
+Do not use all primitives in one scene. One scene grammar, one hero visual, one supporting system, and one continuity carrier are usually enough.

+# Worked composition references
+
+Use these as reasoning examples, not layouts to copy. Preserve the method—extract subject materials, choose a carrier, vary spatial grammar, author resolved states—while changing the actual design for each brief.
+
+## Example 1: A short history of large language models
+
+**Weak default:** dark background, top-left heading, one generic diagram per scene, yellow circles and lines everywhere.
+
+**Subject materials:** paper typography, token rows, attention matrices, parameter scales, chat turns, image crops, waveforms, syntax bands.
+
+**Visual system:** near-black research desk; warm paper-white type; amber signal as the historical carrier; mint/red only for meaningful comparison. Display type is dense and editorial; labels feel measured and technical through weight, spacing, and alignment while preserving approved casing.
+
+**Sequence:**
+
+1. Title wall: a giant cropped `2017` sits behind the title; a Transformer paper fragment occupies the right third; the amber signal is already visible at frame 0.
+2. Attention: the paper fragment expands into a full-height attention matrix; token rows activate and contextual arcs resolve over it.
+3. Scaling: the same amber path becomes a measured logarithmic climb with anchored model eras, exact values, and a large terminal data mark.
+4. Chat: the path straightens into a cursor rail; two oversized conversational turns displace the prior chart rather than appearing inside small UI cards.
+5. Multimodal: text rows, image crop tiles, waveform bands, and code columns arrive with different material behaviors and converge into one field.
+6. Payoff: the four materials remain visible inside a unified output object while the thesis resolves in large type. The final frame is not a copy of the prior midpoint.
+
+**Why it works:** every scene uses content evidence, the amber carrier provides continuity, and the spatial mass moves from split to full-field to measured comparison to centered convergence.
+
+## Example 2: Product feature launch
+
+**Weak default:** floating browser card, gradient background, three benefit cards, logo and CTA.
+
+**Subject materials:** actual product surface, cursor path, before/after states, real output, brand typography and tokens.
+
+**Visual system:** the product itself occupies 55–75% of the frame. Supporting copy is edge-anchored and never competes with the interface. A cursor/selection path carries the story.
+
+**Sequence:**
+
+1. Open on the finished outcome at full scale, not a logo fade.
+2. Pull back to reveal the product surface and the one action that produced it.
+3. Use a cropped before/after split with one continuous cursor path crossing the divider.
+4. Resolve into the product's output plus one concise proof point.
+
+**Why it works:** the product is the hero visual; graphics explain interaction and outcome instead of wrapping the product in generic marketing decoration.
+
+## Example 3: Data-led explainer
+
+**Weak default:** dashboard grid with many tiny charts and metric cards.
+
+**Subject materials:** one decisive comparison, exact values, baseline, range, annotation, category shape.
+
+**Visual system:** one data mark dominates each scene. Supporting values are large HTML text. Grid lines and ticks are sparse, measured, and consistent.
+
+**Sequence:**
+
+1. Open with the surprising number as a large physical mass beside a clear denominator.
+2. Reveal the baseline and comparison categories from the same origin.
+3. Transform the dominant bar/path into the next scene's scale rather than cutting to a new dashboard.
+4. Resolve with the implication in type while the complete chart remains visible.
+
+**Why it works:** data has tangible visual weight; the audience sees a relationship, not a collection of interface widgets.
+
+## Example 4: Abstract systems concept
+
+**Weak default:** four labeled nodes around a glowing center.
+
+**Subject materials:** pick a physical behavior that matches the argument—branching, compression, collision, sorting, accumulation, or convergence.
+
+**Visual system:** each input has a different geometry and motion behavior. The center is not meaningful until the inputs visibly change it.
+
+**Sequence for convergence:**
+
+1. Inputs already occupy distinct edges of frame 0.
+2. Each input crosses a measured boundary and changes form.
+3. Intermediate relationships become visible through paths, masks, or shared alignment.
+4. The resolved object contains recognizable traces of every input.
+
+**Why it works:** the animation demonstrates the concept. Labels support the transformation rather than substituting for it.
+
+## Applying the examples
+
+Before generating HTML, write a one-line comparison internally:
+
+```text
+The weak default would be [generic composition]; this brief instead uses
+[subject material] as [hero visual] and carries [recurring object] across scenes.
+```
+
+If that sentence could describe any topic, the direction is still too generic. Revise it before coding.

+description_en: VideoStudio's canonical gate-authorization and transition policy. Maps user decisions, artifact scope, and native QA state to one next action without duplicate confirmations or false recovery gates.
+---
+
+# gate-control
+
+This is the **single canonical policy** for VideoStudio gate decisions,
+post-gate edits, and recovery across COMPOSE, AUTO, GENERATE, and EDIT. Line
+Skills describe artifacts and production operations but never create a competing
+authorization policy.
+
+## Decision kernel — apply this before the detailed rules
+
+Resolve every turn from the latest durable facts:
+
+1. **Identify the current candidate and pending user decision.** A pending
+   decision is status, not permission to ask again.
+2. **Classify the dependency.** Only a genuine user decision about a creative or
+   delivery choice, or a new billable attempt, is a user dependency. Missing
+   files, stale locators, parameter-shape errors, interrupted operations,
+   equivalent metadata changes, and QA failures with passes remaining are system
+   work and do not justify stopping. An exhausted visual-QA cycle is a creative
+   fork: show its evidence/options and wait.
+3. **Choose one result-aware execution horizon.** Execute only operations whose
+   preconditions are true. If one result decides the branch, stop the horizon at
+   that operation, inspect it, and select the next operation in the same turn.
+4. **Use exact interfaces.** In `calls`, keep the exact native operation token or
+   named Skill/file operation. Do not add a `video_studio.` prefix, invent
+   generic recovery/status, or replace an operation with prose. Include mandatory bindings such as AUTO child's
+   `composition.approve_plan`, `plan_path`, and `segment_id`.
+5. **End in exactly one place:** another immediately executable operation, one
+   of the five stopping decisions with its current artifact, completed delivery,
+   or an external uncertainty boundary with the current artifact and concrete
+   options. Showing an artifact is not an ending except at those five stops.
+
+### Direction-to-plan handoff
+
+Keep the first two stops mechanically distinct:
+
+- **Direction stop:** route and lock facts already settled by the brief, then
+  show two or three concepts without writing a manifest, script, narration copy,
+  or art direction. Use the exact localized name from the table below; in
+  Chinese this is `制作方向确认`, never a renamed label.
+- **COMPOSE plan stop after direction choice:** call `speech.capabilities`, write the canonical
+  `project/composition/composition-manifest.json` from the chosen concept, then run the free `composition.check_narration_fit`; only after those concrete
+  results present the one `制作方案确认` / `Production plan confirmation`.
+
+## Stopping test
+
+Before ending a turn on a user decision, all must be true:
+
+- it is direction, production plan, paid generation, keyframe preview, or final
+  video;
+- that decision is not already pending;
+- the exact complete review artifact exists now;
+- every native prerequisite succeeded for that exact candidate;
+- no call after the question depends on its future answer.
+
+If any item is false, do not stop. A user question, stale reply, already-pending
+decision, technical recovery, or conditional “ask after QA passes” never ends a
+turn on the user. After a local visual mutation, no artifact exists until the
+mutation plus required `composition.inspect` and `composition.snapshot` calls
+succeed. In a planned trace, name those calls rather than emitting `calls:[]`.
+
+An unknown external provider outcome is not recoverable by repeatedly calling a
+status operation without query/reconcile capability. Preserve the transaction.
+If the user explicitly requests a new billable attempt and current status already
+contains a sufficient quote, the only dependency is one fresh Paid generation
+confirmation. For COMPOSE narration, an exhausted retry episode stops automatic
+requests but is not a permanent refusal: with no fresh user decision, show the
+current artifact and the native one-request retry offer; when a new real user
+turn explicitly approves that offer, call `composition.materialize_narration`
+once with current-turn evidence. Never reuse an older turn or route narration
+through Paid generation confirmation.
+
+## No-runtime branch
+
+When the current transport cannot execute production tools or render media, do not stop at the plan confirmation. Return the complete explicitly unexecuted production package:
+assumptions, script/narration, timed storyboard, exact visible copy/captions,
+visual/audio actions, provenance/fallback assets, export target, preview review,
+and final QA. Do not claim media exists. Identify each source as user-supplied,
+self-authored/generated, or third-party; third-party use needs source, license,
+retrieval date, and a project ledger. Without licensed music, specify silence or
+a future rights-safe search.
+
+The active line Skill owns any line-specific additions to this package; do not
+load another line's references on an ordinary runtime path.
+
+## User-facing names and presentation boundary
+
+`Gate A/B/C/D` and `*_decision` are internal. They may appear in diagnostics,
+tests, and calls, but not normal user-facing headings, progress, or explanations.
+
+| Internal protocol | Chinese UI | English UI |
+| --- | --- | --- |
+| Gate A | 制作方向确认 | Direction confirmation |
+| Gate B | 制作方案确认 | Production plan confirmation |
+| Gate C | 付费素材生成确认 | Paid generation confirmation |
+| Preview Gate | 关键帧预览 | Keyframe preview |
+| Narration retry | 旁白重试确认 | Narration retry confirmation |
+| Gate D | 成片确认 | Final video confirmation |
+
+Do not write hybrids such as “Gate B（制作方案确认）”. Describe the missing
+action/artifact directly and keep error codes diagnostic. Never expose
+`budget_exhausted`, “QA budget”, or retry counters. Explain that prior repair
+strategies did not resolve the visible finding and present plain-language
+options.
+
+Every prose span outside a tool call is user-visible. At a successful keyframe
+preview, lead with the current contact sheet/frames, say in one short sentence
+that it is ready, then ask one question: name changes, or reply `继续` / `continue`
+to start the draft. Passing checks and advisories stay silent. Do not expose raw
+finding codes, internal frame roles, signatures/state, operation names, or
+technical go-ahead reasoning unless the user asks for technical detail.
+
+`E_GATE_B_*` has two classes. `intent_amendment` means approved intent changed
+and goes through one Production plan confirmation. `artifact_repair` means the
+plan file is missing, unparseable, incomplete, or not amended: repair and retry
+in the same turn without asking the user.
+
+Whenever a quality finding blocks progress, tell the user what is visibly wrong
+and that they may skip it if they accept the look. Their current words authorize
+rerunning the same blocked operation with `waive_qa_findings` and
+`decision_evidence={source:"user_message",gate:"qa_waiver",decision:"approve",quote}`.
+The waiver persists, so do not ask twice. Missing/corrupt evidence cannot be
+waived. Segment-level findings in an assembled production continue with other
+segments and surface at the production review; never create a segment gate.
+
+## Confirmation artifacts — load only at a stop
+
+Before presenting or consuming any of the five stopping decisions, or handling
+a COMPOSE narration retry, read
+[confirmation-artifacts.md](references/confirmation-artifacts.md). It owns exact
+artifact content, locator rules, gate table, video-language default, the once-per-
+visual-identity preview, and narration retry presentation. Do not load it for a
+pure technical recovery that will not reach a user stop.
+
+For narration identity drift, ledger exhaustion, old-session decisions, or
+measured-duration convergence, additionally read
+[narration-recovery.md](references/narration-recovery.md). The model never counts
+or resets attempts itself.
+
+## Authority is not recovery
+
+Interpret the complete current real user reply with the visible pending artifact
+and durable facts. When it clearly approves, revises, or rejects a named gate,
+call the authorized native operation with a native-object
+`decision_evidence={source:"user_message",gate,decision,quote}` whose `quote` is
+verbatim from that message. A legacy form submission remains consumable without
+`decision_evidence`. Mixed approval plus change is `revise`; genuinely ambiguous
+target gets one concise question. A reply selecting an option just enumerated—
+`2`, its wording, or a paraphrase—is the decision; act without asking it again.
+
+`E_DECISION_EVIDENCE_INVALID` with
+`current_user_message_available:true` and `user_reconfirmation_required:false`
+is an agent-owned shape correction: fix the object and retry once immediately.
+`E_DECISION_EVIDENCE_NOT_FROM_USER` is not a shape problem; requote only if the
+user really decided, otherwise show the review artifact and end.
+
+| User decision | Capability granted |
+| --- | --- |
+| named change to visible artifact | apply that bounded scope |
+| approval of displayed plan | sign that plan payload |
+| approval of displayed billable generation | authorize exactly that intent |
+| approval of displayed narration retry | authorize one new request after the shown uncertain attempt |
+| approval of displayed finished video | export that draft signature |
+| legacy `visual_recovery_decision=new_visual_revision` | consume old visible recovery only; never emit it anew |
+
+## Required transition resolution
+
+After any gate submission, post-gate revision, or visual-revision error:
+
+1. Call the owning `composition.status` or `production.status` first; do not do
+   broad manifest/HTML reads or execution-plan bookkeeping first.
+2. Classify scope as `visual_only`, `gate_b_payload`, or `unknown`.
+   `visual_only` covers styling/layout/motion/assets without signed copy,
+   narration, timing, language, delivery, source mapping, or role changes.
+3. Set recovery from native evidence only: `available` solely for current
+   exhausted-cycle evidence requiring a new user revision; `not_available` for
+   a current/pass/non-exhausted cycle; otherwise `unknown`. Old-signature
+   recovery is irrelevant to a new signed amendment.
+4. Run the bundled resolver and obey `next_action`, `allowed_ops`, and
+   `prohibited_ops`. Pass only the current submission's decision field.
+
+Even in a planning-only benchmark, name `composition.status`/`production.status`
+and `gate-control resolve-transition` as separate ordered steps.
+
+Pass `--origin` on signed-payload revisions. A current user-named change uses
+`origin=user`: apply it without a new confirmation and quote it in
+`decision_evidence`. A model-authored change or mixed user instruction plus model
+proposal uses `origin=model` and requires the one plan confirmation.
+
+Invoke the resolver only through the standard Skill Runner:
+
+```bash
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" gate-control resolve-transition -- --line compose --artifact composition --gate gate_d --decision revise --scope visual_only --recovery not_available
+```
+
+Line values are `compose`, `auto`, `generate`, `edit`; artifact values are
+`composition`, `production`. AUTO passes `--artifact composition` for a child.
+Use exact enum values and `unknown` for missing evidence. When a current decision
+is present, omit old `--artifact-state` and `--approval-status`.
+
+## Conditional transition references
+
+- Before AUTO child preview, segment revision, or whole-production assembly,
+  read [assembled-productions.md](references/assembled-productions.md). It owns
+  the one-video preview artifact and per-segment change scope.
+- After a post-gate revision, stale/superseded candidate, exhausted visual-QA
+  cycle, reconciliation, or artifact-validation recovery, read
+  [revision-and-recovery.md](references/revision-and-recovery.md). It owns
+  freshness, invalidation, amendment ordering, decision budget, and continuation.

+
+# Assembled productions are one video
+
+An AUTO production is authored as one composition per segment, but the user made
+one video. The number of times it stops for them is fixed by the gate table in
+`gate-control` and never grows with the number of segments.
+
+- **The complete frame set is the keyframe preview stop.** When
+  `production_review.uncaptured_segment_ids` is empty and before any assembly
+  operation, end the turn with the whole production's frames and their exact
+  locators, one line inviting changes, and `<plan-interaction status="open" />`.
+  Segments never get their own stop — seven segments still make exactly one
+  preview message. A segment with nothing to show is not ready to present — run
+  its QA phase first.
+- **The production's own contact sheet is that stop's artifact.** The batched
+  snapshot phase returns `production_contact_sheet` — one image of the whole
+  video, segments in playback order, media segments included as an extracted
+  still. Lead with it, then list each segment's locators beneath. A media
+  segment — a cut of the user's own footage, a generated shot — has no
+  snapshot because its own file is the artifact: carry its `produced_path` so
+  the user can play it. Never substitute one contact sheet per child.
+- **A user-requested change to one segment is applied without re-asking.** They
+  named the change, so applying it is already authorized. Before the
+  production's preview go-ahead, apply the edit, re-capture that segment, and
+  answer with ONE message: what changed, the re-captured frames' locators, and
+  the same one-line go-ahead question — never a separate confirmation of the
+  change itself; the host refuses per-segment approvals with
+  `E_SEGMENT_HAS_NO_USER_GATE`. The same holds for a repair they told you to
+  make. After the go-ahead — or once assembly is under way — a named change or
+  internal repair is applied, its re-captured frames are published as
+  progress, and the work continues without stopping: the finished video is the
+  next stop.
+- **Editing one segment does not disturb the others.** An edit drops only that
+  segment back to uncaptured. Re-run its QA phase and leave every other segment
+  alone — never re-render or re-check an unchanged segment because a sibling
+  changed.
+- After its plan, an assembled production stops twice: the keyframe preview
+  and the finished video.

+# Confirmation artifacts and stopping protocol
+
+## Show the work; stop only five times
+
+VideoStudio emits no confirmation forms. The input channel is plain prose:
+never emit `<agent-input-form>`, and do not treat retired forms in conversation
+history as examples. Every artifact is shown in an ordinary message. User-
+requested changes and repairs are already authorized; never confirm them again.
+
+Exactly five decisions stop the run: direction, production plan, paid
+generation, keyframe preview, and final video. Present the current artifact with
+its exact locator, a concise next-action/cost/QA note, one direct question, and
+`<plan-interaction status="open" />`; then call no more tools. Revised shots,
+repairs, and partial progress are not stops: publish them and keep producing.
+The same closing marker applies to any other message that hands the next step
+to the user — a blocked report, an exhausted repair budget, a missing
+capability: without it the runtime reads the stop as an unfinished turn and
+bounces the reply.
+
+## Direction and preview
+
+Direction comes before any plan file. Route the request, resolve locked brief
+facts, then show two or three genuinely different concepts for the same brief:
+one-line name and description each, locked production line/aspect/duration/video
+language/audio mode/supplied-asset usage/cost note, and one question. Write no
+copy, narration, manifest, or art direction yet. A brief that already specifies
+the video still stops here with one concept.
+
+The keyframe preview is the stop between capture and rendering/assembly. When a
+standalone composition's full snapshot set exists, or an assembled production
+has no `uncaptured_segment_ids`, end the turn with every frame's exact locator
+and one invitation to change it or reply `继续` / `continue`. Only a later real
+user reply naming no change is go-ahead. An empty, unrelated, question-only,
+delegated, or background-resume turn is not. Status/read/repair never records
+go-ahead.
+
+The preview stop happens once per visual identity. Narration text, voice, audio,
+or narration timing changes preserve silent frames and their go-ahead when
+scene windows and visible output are unchanged. Visible copy, layout, assets,
+scene order/windows, or motion creates a new identity: capture and show the new
+complete set once. Unchanged internal recaptures publish progress and continue.
+
+Until the user replies, `composition.draft` returns
+`E_PREVIEW_GO_AHEAD_REQUIRED` with frame paths. Do not retry or bypass it. A new
+user turn is interpreted semantically by the model choosing
+`composition.draft`; the host verifies the prior-turn preview and current visual
+identity. Preview go-ahead uses no `decision_evidence` and is not stored by
+`composition.status`.
+
+## Exact artifact locators and pending decisions
+
+“Show the current artifact” must be executable. Carry the exact current artifact locator
+returned by native state—the contact-sheet and frame-path set, or complete draft/video path—into both the
+review package and user response. Never publish a superseded locator or replace
+it with “show latest”. If the user asks a question while a decision is pending,
+answer from current artifact locators and leave the decision pending without
+asking again. Negated prose is not approval.
+
+Only a real user turn decides a gate. `E_GATE_USER_TURN_REQUIRED` with
+`current_user_message_available:false` and `next_step_owner:user` means show the
+artifact, ask once, and end. Never retry in that turn or treat delegated task
+text as the user's decision.
+
+## Gate artifact table
+
+| Gate | Required review artifact | Evidence gate | Approved transition |
+| --- | --- | --- | --- |
+| Direction | two or three concepts plus locked facts; no plan file | `direction_decision` | write plan from the chosen concept |
+| Production plan | locked direction summary plus COMPOSE manifest/narrator or production EDL; an unapproved EDL's native `plan_summary` is presented verbatim once | `gate_b_decision` | composition -> `composition.approve_plan`; production -> `production.approve_plan` |
+| Paid generation | exact billable segment count plus current credit/billing evidence | `gate_c_decision` | `production.approve_generation` before provider call |
+| COMPOSE narration retry | current visual candidate, uncertain prior request, and exactly one proposed new request | `narration_retry_decision` | one fresh `composition.materialize_narration` transaction |
+| COMPOSE narration timing | complete audio, measured duration/band, visual readiness, and exhausted automatic timing retry | `narration_retry_decision` | one user-authorized synthesis or duration waiver using complete audio |
+| Final video | draft plus QA headline plus the draft result's `delivery_options` | `gate_d_decision` | composition -> `composition.approve_draft`; production -> `production.status` delivery check |
+
+At the final-video stop, show both `delivery_options` with their
+`estimated_minutes` so the wait is chosen knowingly. A plain confirmation
+exports the high-quality default; picking the faster preview-quality option is
+itself the user's acceptance of the lower quality — pass its exact `call`
+parameters and ask nothing further.
+
+## Production plan content and language
+
+The Production plan opens with the locked direction summary—line, aspect,
+duration, video language, audio mode, supplied-asset usage, and billable cost
+note—then the plan digest. It restates rather than reopens settled facts. Preserve
+every explicit brief constraint; concepts live inside those constraints. Do not
+interrogate the user for open casting, ethnicity, audience, style, tone, or
+visual preferences unless truly missing and blocking.
+
+Resolve initial video language from explicit request, then User UI language,
+then English. Map `zh`/`zh-CN` to `zh-CN`, `en`/`en-US` to `en`, `ja`/`ja-JP`
+to `ja`, and `pt`/`pt-BR` to `pt-BR`;
+unavailable or unsupported UI language falls back to `en`. The
+supported deliverable languages are English, Simplified Chinese, Japanese, and
+Brazilian Portuguese. State it in the plan and write plan artifacts in that
+language. A reply changing language is a revise instruction: rewrite canonical
+files and show the one updated plan, never approve mismatched files. Later UI
+language changes do not alter the locked deliverable language.
+
+For a production EDL, present native `plan_summary` verbatim once. If the user
+already answered while `plan_approval_current:false`, the transition is owed;
+never present the plan again. Plan approval authorizes only the owning
+`approve_plan`, never paid generation, render, or export. Send `task_title` on
+every plan confirmation/amendment in the user's words; keep it stable unless the
+task changes and omit rather than invent it.
+
+## Paid generation and narration retry
+
+Paid generation may open only from a current signed plan and fresh
+`production.status` whose quote is available and sufficient. Show billable
+generation count; expected, maximum/required, and available credits; managed
+fallback coverage; and externally billed/unverified segments. A failed or
+pending provider attempt is not reusable authorization. If the latest status
+already has current quote/signature and an unreconcilable outcome, do not query status again.
+If the user explicitly asked to retry, open that fresh Gate C immediately with no host call;
+only later approval dispatches a new output path. Never
+interleave shot confirmations.
+
+COMPOSE narration is not Gate C. When materialization returns an uncertain prior
+request plus `narration_retry_offer`, first complete and expose the visual
+candidate. Explain that usable narration was not returned and may have been
+charged, show that the proposal sends exactly one new request, and use
+`narration_retry_decision`. A clear user reply calls
+`composition.materialize_narration` with native-object decision evidence. The
+host consumes one real user turn once, archives the failed transaction, and
+creates one fresh attempt. Never reuse an earlier reply or ask again after the
+same attempt succeeded.
+
+For identity drift, ledger exhaustion, old-session submissions, or measured-
+duration convergence, read `narration-recovery.md`. Core timing uses target plus
+or minus `max(target * 5%, 5s)`, accepts in-band audio, permits one native-owned
+automatic timing revision, then presents exactly two visible choices. “Proceed”
+must state that complete current audio is kept without truncation. The model
+does not count attempts or send another request without current authority.
+
+An AUTO child inherits parent plan approval only through
+`composition.approve_plan` with owning `plan_path` and `segment_id`; mismatch
+returns to the single parent EDL plan confirmation, never a child gate.
+
+A narration-retry rejection is recorded by the same operation:
+`composition.materialize_narration` with
+`decision_evidence={source:"user_message",gate:"narration_retry",decision:"reject",quote}`.
+It sends no provider request; do not invent a “record rejection” operation.

+# Narration recovery and duration decisions
+
+Read this reference whenever COMPOSE narration identity changes, a retry ledger
+is exhausted, an old-session decision arrives, or measured audio misses its
+approved duration band.
+
+## Stable request identity and uncertain provider outcomes
+
+Narration confirmation identity follows the stable synthesis request:
+narration text, `route_ref`, `voice_ref`, language, speed, and format. Catalog
+display names, provider implementation labels, paths, formatting, and other
+locator/presentation metadata are not user-approved intent. Refresh those
+facts internally without reopening Production plan confirmation or replacing
+an already-recorded one-request retry authorization. If a non-billable local
+check interrupts dispatch, call the repair/reconcile operation and resume the
+same persisted authorization; never ask for it again.
+
+A user-requested narration change — voice, speed, language, or script wording —
+is a revision of the SAME composition: amend the signed selection
+(`audio.narration_intent` on schema 2; the `voice` parameter on schema 1),
+approve the amendment with the user's own change message as evidence, and
+re-run `composition.materialize_narration`. Never create a new composition or
+candidate line for an audio-only change: the visual identity, preview
+approval, and every visual artifact carry over unchanged, and rebuilding them
+replays every confirmation the user already gave. Rebuild only when the host
+leaves no in-place path — a blocked narration invariant that the listed
+recovery operations cannot clear — and tell the user why before doing it.
+When re-materialization succeeds with visual identity unchanged (the result
+says `redraft_same_turn_then_final_video_stop`), continue in the same turn to
+`composition.draft` — the prior video track is reused, so it completes in
+seconds — and present the new-voice draft at the final-video stop as the
+single audition and confirmation, with the narration audio attached. Do not
+stop for a standalone audio audition first: one listen, one decision.
+
+The native narration transaction ledger owns convergence. When it returns
+`E_TTS_RETRY_EPISODE_EXHAUSTED`, the unchanged request has reached its automatic
+uncertain-outcome boundary, not a permanent user-retry prohibition. The result
+keeps the current visual candidate and supplies a `narration_retry_offer` for
+exactly one additional billable request. If no fresh user decision exists in
+the current turn, present that candidate, the unresolved billing risk, and one
+`narration_retry_decision`; send no request and end the turn. Do not open Paid
+generation or Production plan confirmation.
+
+A new real user turn that clearly approves the displayed retry — including a
+plain request such as “continue generating narration” — authorizes exactly one
+`composition.materialize_narration` call with native-object
+`decision_evidence={source:"user_message",gate:"narration_retry",decision:"approve",quote}`.
+This remains true after any number of earlier inconclusive requests: the native
+ledger persists the new authorization before dispatch and binds it to
+`authorized_turn_id`, so replaying that same turn cannot send twice. If the new
+request also fails inconclusively, automatic continuation stops again and a
+later real user turn may make a new one-request decision. The model never
+counts, resets, or overrides attempts itself.
+
+Historical conversations may contain an older host result saying there is no
+retry offer, or that a submitted retry was
+`superseded_by_current_transaction_ledger`. Those fields describe what happened
+in that old turn; they are not a permanent prohibition after the host/Skill is
+upgraded. Never reuse the old reply, but if the current real user newly asks to
+retry, call `composition.materialize_narration` with evidence from the current
+message and let the native ledger decide. A question or a reply that does not
+approve a new request leaves the retry pending and sends nothing.
+
+## Measured-duration convergence
+
+Measured-duration convergence is a separate durable episode from an uncertain
+provider retry. Estimated and measured narration both use the native-reported
+narration target plus or minus `max(target * 5%, 5s)`. That target is the
+approved delivery duration after explicitly silent scene windows are reserved;
+those windows are not speech budget. An in-band result is accepted immediately;
+never trim the text or synthesize again merely to hit the nominal target.
+
+After an out-of-band initial result, native permits one automatic
+timing-focused text revision and one revised synthesis across the changed
+`text_sha256`. When that request returns
+`E_NARRATION_TIMING_USER_DECISION_REQUIRED`, show the current complete audio,
+measured duration, accepted band, and truthful current visual
+artifact/readiness. Open exactly one `narration_retry_decision`, leading with
+the host-recommended default and one direct question — not an open
+questionnaire:
+
+- Proceed (recommended default): keeps the complete current audio, records a
+  duration waiver, and retimes without truncation. Present it as what happens
+  on a plain "好/确认" reply.
+- Revise again (alternative): authorizes one additional synthesis after the
+  free fit check.
+
+The visible proceed choice must explicitly say both that the complete current
+audio is kept and that it will not be truncated; never leave either consequence
+implicit in a generic “proceed” or “retime” label. End the turn. Do not send
+another speech request, reopen Gate B/C, reset or recount the persisted episode,
+or describe a runtime scaffold as completed visual engineering.
+
+A direct reply selecting another revision is current-turn authority for the
+bounded edit/check/prepare/materialize path and exactly one additional speech
+request. A direct reply selecting progress with the current audio is recorded
+by `composition.materialize_narration` with
+`decision_evidence={source:"user_message",gate:"narration_retry",decision:"reject",quote}`.
+That call reuses the existing audio, sends no provider request, records the
+waiver, and expands actual composition timing when needed. Questions about the
+choice leave it pending and send no request.

+and send independent mutations in one message before the exact validator. Stop
+at the first call whose result determines the next branch. The executable path
+ends at the next user gate and never includes an approval, billable dispatch,
+draft, export, or operation depending on that future answer.
+
+Every revised preview, draft, generated shot, edited output, or assembly is a
+new immutable candidate descended from its predecessor. A successor supersedes
+earlier review eligibility without deleting history. Before presenting or
+consuming a decision:
+
+1. read owning native status;
+2. expose the complete current primary artifact, never a compatibility thumbnail;
+3. preserve earlier accepted deltas and unaffected segment outputs;
+4. bind the gate to current candidate/signature;
+5. acknowledge a reply aimed at a superseded candidate but do not apply it—show
+   the current candidate without requesting technical recovery confirmation.
+
+For COMPOSE, a changed snapshot publishes its full new `frame_paths` and contact
+sheet. A visual change gets one new preview stop; narration-only change preserves
+the silent preview. A changed draft invalidates earlier Final video confirmation
+and export. EDL lines reprocess only affected segments, while the review artifact
+represents the complete current video.
+
+Local scene edits preserve unaffected sources, narration, paid transactions, and
+accepted deltas. Aggregate contact sheet, sampled frames, design verdict,
+preview go-ahead, draft, and final approval are bound to the whole candidate and
+become stale for its successor. Invalidating aggregate review never means
+rebuilding unaffected scenes. Before publishing COMPOSE frames, name and complete
+your own frame check of the exact current snapshot; a conditional description is
+not a native verdict.
+
+## Transition invariants
+
+- Gate D `revise` with `visual_only` and recovery `not_available` goes directly
+  to localized edit plus owning reconcile/QA, then the next real artifact gate.
+- A changed raw file hash is candidate evidence, not automatically a plan
+  amendment. If status says `plan_approval_current:true`, refresh locators/hashes
+  through reconcile and continue QA. Amend only when normalized approved intent
+  changed.
+- Approval identity is fail-closed user intent. Content, media/voice refs,
+  language, speed, duration, and delivery constraints remain signed. Runtime
+  facts and catalog presentation metadata do not reopen the plan. Unknown fields
+  remain intent until their owner classifies them.
+- No operation restarts an exhausted visual-QA cycle. Show current frames and
+  findings, offer another repair round or skipping the named check, and end. A
+  later real reply grants the next cycle; make a materially different edit.
+- `gate_b_payload` revision opens exactly one plan amendment. Approval applies
+  the bounded patch and `composition.approve_plan`; visual evidence survives
+  only when native reports unchanged visual identity.
+- Legacy `recovery-decision=new_visual_revision` input consumes the already
+  visible old request and continues QA; never emit it anew.
+- `E_VISUAL_REVISION_NOT_REQUIRED` continues the existing cycle.
+- `E_VISUAL_REVISION_EXPLICIT_AUTHORIZATION_REQUIRED` requires status: continue
+  a non-exhausted cycle; for exhausted recovery without a current decision, show
+  findings/options and end. The error never starts a cycle.
+- Old approval for an unchanged signature is usable only when the current turn
+  has no new decision. Current decision always wins.
+- Passing snapshot may create one preview only without recorded go-ahead;
+  passing draft may create one final-video stop. No technical step creates other
+  user gates.
+- Export is authorized here only. Default technical settings are host-owned; do
+  not ask users for container/resolution/bitrate. Successful export creates no
+  new preview or final-video gate.
+
+## Signed amendment ordering
+
+For a plan-amendment submission:
+
+1. Apply the exact bounded patch shown in the approved amendment.
+2. Call `composition.approve_plan` with `expected_plan_change:true` after the
+   files change while the current real message carries approval. A current-turn
+   message that explicitly names the change ("换成XX的声音", "把结尾标语改成…")
+   IS that approval for exactly the named change: submit
+   `decision_evidence={source:"user_message",gate:"plan",decision:"approve",quote:<the user's change request>}`
+   and do not present the amended plan for another confirmation round. Only
+   what goes beyond the named change still needs presenting.
+3. Require `plan_changed:true`; native clears the draft and reports whether
+   visual evidence survived. Narration-only keeps it; visual change clears
+   preview/go-ahead/visual QA together.
+4. Continue from `next_action`, rerunning visual QA/preview only if visual identity
+   changed.
+
+On `E_GATE_B_AMENDMENT_NOT_APPLIED`, synchronize the exact approved patch and
+retry approval in the same turn; do not ask. Never run lint first and turn
+`E_GATE_B_ARTIFACT_CHANGED` into a technical confirmation. Never promise
+immediate render when a later preview must review a new artifact.
+
+## Decision budget
+
+One user decision creates at most one follow-up authorization request, only for
+a capability not granted:
+
+- signed payload changed -> Production plan confirmation;
+- uncertain COMPOSE narration plus one displayed fresh request -> narration retry;
+- same payload exhausted one QA cycle -> show evidence/options and wait; later
+  reply grants the next cycle;
+- approved plan amendment -> fresh QA, never combined recovery question;
+- otherwise -> do not ask.
+
+Never add a preliminary authorization before the five stops. A current revise
+message that names its patch needs no separate permission. Questions, status,
+bookkeeping, advisory QA, remaining passes, reconciliation, and tool misuse do
+not stop for the user. An exhausted cycle does. The plan confirmation is a
+reviewable summary, not a questionnaire; preserve constraints and resolved
+language. Replacing an unapproved candidate is bounded file editing plus exactly
+one updated plan message, with no gate operation.
+
+## Reconciliation and continued execution
+
+Treat simultaneous non-user inconsistencies as one fact-reconciliation problem:
+orphaned `active_operation`, relocated equivalent plan records, stale derived
+approvals, recoverable transactions, or candidate drift. COMPOSE uses
+`composition.reconcile`. Production EDL lines have no `production.reconcile`:
+refresh excluded runtime locators/records, then run the concrete affected
+edit/generate/assembly. Never invent a production reconcile or send locator-only
+repair through the gate resolver.
+
+Preserve approved intent, paid-transaction identity, and candidate ancestry;
+invalidate only mismatched derived facts. Continue in the same turn through
+non-billable operations/QA until a real user artifact or completed delivery is
+ready. Do not stop at “state recovered”, defer rebuilding, blindly repeat the
+interrupted operation, or ask how to continue.
+
+If current status is already available, do not repeat it or call the resolver
+for non-user reconciliation. The resolver is for real gate submissions or
+revision boundaries; technical recovery follows native facts directly.
+
+Every quality result also delivers an artifact. Keep native
+`current_candidate` HTML locator, content hash, preview/contact sheet, sampled
+frames, draft, findings, and report attached to one revision. On failure, show
+available artifact/findings as the current unapproved version while continuing
+internal recovery. When `review_package.presentation_required:true`, surface
+its primary artifact and plain-language conclusion in the same response. If
+media does not exist, surface manifest or authored HTML. Passes remaining
+continue; exhausted cycle shows evidence-grounded choices and waits.
+
+Artifact validation failure does not invalidate a real user decision. If native
+returns `approval_received:true`, `user_reconfirmation_required:false`, and
+`automatic_recovery_expected:true`, preserve approval, repair exact
+`artifact_issues` without changing meaning, retry the same approval in the
+current turn, and continue. User copy omits error identifiers and explains the
+file/field repair and preserved confirmation.
+
+When `next_step_owner:agent` and `execution.continue_in_current_turn:true`, this
+is an execution instruction. A valid trace includes concrete
+`edit_file <path>`, retry, then the next result-aware production operation. A
+diagnosis-only answer or new question is incomplete.

+
+How to execute a validated, currently authorized `project/plan.json` into one finished file. Start/resume with `production.status`; if `plan_approval_current` is false, pass the state to `gate-control` and stop instead of producing or opening child gates. Walk the signed EDL; do not re-plan. Host-neutral: VideoStudio-specific edit/plan work runs through skill scripts (`stage-edit edit_video`, `stage-plan video_plan` via `bin/run-skill.cjs`), while authorization state, composition, and transcription run through the required built-in `video_studio` runtime; generic built-in capabilities remain `generate_video` / `generate_image` / `generate_speech`.
+
+## Script calls used here

+Iterate segments in `order`. For each, produce its `produced_path` according to `source`, then write that path + `status:"done"` back into the segment so a resume never re-produces it:
+
+- **edit** → `stage-edit`: cut the segment's `input_id` to its `[in_sec, out_sec]` window → `project/cuts/<id>.mp4`. Those are the EDL's field names, not flags: the command is `stage-edit edit_video --op trim --input <file> --start <in_sec> --duration <out_sec - in_sec> --output project/cuts/<id>.mp4`.
+- **compose** → `stage-compose`: the host derives this child's `composition-manifest.json` from the signed segment's `spec.composition_plan` when the plan is inherited — do not hand-author it, and author only `index.html`. Keep it silent: no tracks and no `narration_intent` (the voice is signed once on the parent EDL). Set `audio.owner:"assembler"` whenever any scene carries `narration_text` — it renders silent exactly like `"none"` while naming the real owner, so the host stops asking this segment for its own narration audio. Use `"none"` only for a segment with no narration at all. Ask `gate-control` to resolve parent Gate B inheritance for the owning plan/segment, then follow the returned doctor/prepare path without creating a child user gate. Continue with visual authoring, native-required inspect/snapshot, and draft to `project/parts/<id>.mp4` only while the binding stays current. Run the QA phases for compose segments as ONE batched call per phase across the production rather than one call per segment: the batched path defaults its scope to the segments with no current frames, returns full findings only for the failures, and returns the production state once instead of repeating it per segment. Use a single-composition QA call only to re-check one named segment. Only `compose` segments need snapshot evidence, because their artifact is HTML; an `edit`/`generate`/`provided` segment is captured by its own `produced_path` file the moment that file exists, so never run a QA phase on one and never treat it as unfinished work. When every segment is captured (`production.status` reports no `uncaptured_segment_ids`), stop at the keyframe preview. The batched snapshot phase returns `production_contact_sheet`: ONE image of the whole video, segments in playback order, media segments included as an extracted still. Lead the stop with it — it is the artifact the user judges the video from. Then list each segment's own locators **in playback order, one row per segment including the media-backed ones** (a cut or generated shot has no snapshot — carry its `produced_path` so the user can play it), one line inviting changes, and `<plan-interaction status="open" />` — no form, no per-segment approvals. Never present a per-segment contact sheet as the production preview: four links to four children is not a look at the video. Assembly starts only from the user's reply; a reply that names no change is the go-ahead, while a named change is applied without asking the user to approve their own instruction. Re-capture the resulting complete production preview and return it in the next preview message — the message that ENDS the turn. A completed turn keeps only your final message, so frames posted mid-turn were never seen by the user. Put the updated contact sheet and locators in the turn's last message itself. The stop happens once per complete production visual identity: narration/audio-only work inherits it when every visible segment stays byte-identical; changing any composed frame or media-backed segment creates a new aggregate identity and the changed whole-video preview stops once before assembly. There are still no per-segment approvals.
+- **generate** → `stage-generate` (+ `stage-consistency` for recurring characters): proceed only while `production.status` reports the current paid-generation signature. Call `generate_video` or `generate_image` with `production_plan_path:"project/plan.json"` and `production_segment_id:<id>` → `project/assets/<id>.<ext>`. When the segment has `operation:"edit"`, treat it as the bounded semantic-edit executor for the EDIT/AUTO workflow: pass the exact original reference video and obey top-level `references` + `edit_strategy`; never widen it into regeneration. Every auxiliary portrait/keyframe is already its own signed generate segment; do not create unplanned billable calls. The host transaction reuses a completed artifact and blocks an interrupted/failed duplicate. Pass pending/failed state to `gate-control`; never automatically retry or invent a recovery API, and use a new output path for any later authorized retry.
+- **provided** → use `spec.asset_id` as-is (probe it first; conform aspect/fps if needed).
+
+Billable `generate` segments must not run until `gate-control` accepts the current signed plan, exact count, configured external provider, external-billing disclosure, and fresh `production.status` transaction evidence, then returns the provider-call transition. The open build cannot verify the provider's billing or balance locally. Produce cheap/free segments first; never interleave per-shot confirmations.
+
+## Step 2 — Assemble in ffmpeg tiers (the default path)
+
+Assemble deterministically, bottom-up. This tiered order is the default; it is predictable and cheap, and keeps each clip's real audio intact:
+
+Treat a track as enabled only when it has executable content: narration needs a signed `synthesis` selection and at least one non-empty line (legacy raw `voice` is recovery-only), music needs a real `path`, and captions need non-empty `lines` or a valid `from` source. Omitted/null tracks and legacy empty objects are disabled; skip them completely. Never synthesize, mix, or burn a placeholder merely because the key exists.
+
+1. **Primary track** — `stage-edit edit_video --op concat` the primary-layer `produced_path`s in `order` → `project/render/primary.mp4`. Conform aspect/fps on the way in if sources differ.
+2. **Overlays / bg** — for each overlay/bg segment, `stage-edit edit_video --op overlay` its part onto the primary over the window of the segment named in `over` (lower-thirds, logo boxes). An overlay part must be smaller than the base frame: composed parts are opaque video with no alpha, so a full-frame overlay would replace the footage instead of compositing over it, and the host refuses it with `E_EDIT_OVERLAY_OPAQUE`. That error is a plan-shape problem, not a retry: re-plan the beat as edge elements or as a composed primary segment (a signed-plan change goes through the one plan amendment), and never work around it by re-encoding, resizing tricks, or hand-written ffmpeg graphs. Composed layers are VISUAL-ONLY — they must not carry their own narration audio. **This includes a compose segment that IS the primary track (a full-video composition): render it SILENT — do not put a narration `<audio>` in its `index.html`. The assembler owns narration (tier 3), so a composition that bakes it in would mean narration is added TWICE (the "two voices" defect).**
+3. **Narration — added EXACTLY ONCE, here.** If narration is active by the rule above, re-check line length against `target_sec` before synthesis; shorten over-budget lines in `project/plan.json` while preserving meaning. Then call `generate_speech` for each line with the plan's exact `synthesis.route_ref`, `synthesis.voice_ref`, and `synthesis.language`, plus `production_plan_path:"project/plan.json"` and that line's zero-based `narration_segment_index`; pass `target_duration` equal to its signed `target_sec`. The host verifies the current Gate B signature, exact text, selection, language, speed, and duration before synthesis, so execution-time overrides are forbidden. Write each line's `produced_path` back so a later edit can re-voice one line alone. Aim for one TTS call per line; allow at most one shortened retry after a real fit failure. Add the produced lines in ONE `stage-edit edit_video --op mix` call using `--audio-segments` — one entry per line, each at its `start_sec` — so each line is delayed onto its scene (per-line placement; do NOT pre-bake one continuous narration file, that destroys per-line alignment and separability). The mix DEFAULTS to `on_existing_audio:"reject"`: if the base already has an audio track it FAILS with `E_EDIT_BASE_HAS_AUDIO` — that means a compose segment baked narration into its render; go back and re-render that segment SILENT, then re-mix. READ THE COVERAGE REPORT on the result and treat it as QA, not decoration: `voicedRatio` is the honest share of the video that carries voice (`coverageRatio` only says how far the LAST line reached — a half-silent track can still score 0.95 on it); `status:"gapped"` with `interiorGaps` means dead air between lines; `status:"overlapped"` or a non-zero `maxOverlapSec` means two lines speak at once (a line's audio ran past the next line's `start_sec`); narration running past the end of the video is not a status to weigh — the mix cuts the last line short, so the call FAILS with `E_EDIT_MIX_NARRATION_TRUNCATED` and there is no file to judge; shorten that line and re-synthesize it, or extend the video, and never raise the speech speed to fit. Neither gapped nor overlapped ships either: re-time the lines inside their scenes, shorten the colliding lines, add the planned music bed, or shorten over-long scenes via the plan amendment; never pad the script with filler words. Fix any desync before the draft. An intended music-only or silent tail is allowed only when stated at Gate D. Keep built-in lip-synced talking-head audio; never synthesize over a speaking mouth.
+4. **Music** — when the music track is active, add its path ducked under narration by the planned amount.
+5. **Captions** — when the captions track is active, resolve `from` or turn `tracks.captions.lines` (`{text, start_sec, target_sec}`) into a `.srt`, then `stage-edit edit_video --op burnsubs`. Skip a caption line whose text merely repeats that scene's visible on-screen copy — burning the same sentence twice on one frame reads as a defect, and captions exist for speech the frame does not already show. Captions are DATA in the plan — burned ONLY here at assemble — so a later typo fix is a one-line edit re-burned, never a re-render of the picture. If `burnsubs` fails because the runtime ffmpeg lacks subtitle filter support, stop and report that blocker; do not hand-write a fallback `ffmpeg` graph, do not use `-loop 1` PNG subtitle overlays, and do not recompose the whole video just to fix captions.
+6. **Loudness** — run `stage-edit edit_video --op normalize_loudness --input project/render/draft.mp4 --output project/render/video.mp4`. It normalizes to the `video-craft` §7 targets (~−14 LUFS integrated, true-peak ≤ ~−1 dBTP) and returns the measured loudness; only fall back to `--op loudness` when you are diagnosing an existing file without writing a deliverable.
+7. **Verify the delivery** — call `video_studio` `production.status` with `delivered_video_path` set to the final file. Its `delivery_check` reads the ARTIFACT against the approved plan — length, canvas, narration placement measured from real speech, loudness, declared captions — so it holds every route to the same bar, including a hand-written ffmpeg assembly. Any `severity:"error"` issue is not deliverable; repair and re-check before Gate D. This is the QA headline that stop needs.
+
+Apply the plan's `style_kit` for cohesion: composed layers (titles/captions/cards) use its `palette` + `fonts`. A single `lut` graded across all clips is what unifies tonally mixed sources — until a grade op is available, keep mixed sources close at capture/trim and lean on the shared palette + consistent captions for cohesion rather than promising a uniform grade.
+
+Output `project/render/video.mp4` as the deliverable; `project/render/draft.mp4` is the pre-normalized intermediate.
+
+**Record the delivery in the plan.** When the deliverable exists (and again after any re-render), write its path into `project/plan.json` under the runtime envelope — `"_runtime": {"render": {"final_path": "project/render/<file>.mp4"}}` — alongside the per-segment `produced_path` write-backs. `_runtime` and `produced_path` are runtime locators excluded from the signed plan identity, so these writes never re-open the plan confirmation; skipping them is what leaves the review drawer claiming an already-delivered video was never started. The plan is the production's record: a file only you know about does not exist for the user's review surfaces.
+
+## Director judgment (end-to-end assembly)
+
+The craft of making mixed sources feel like one video, on top of the shared craft (`video-craft`). The seams between footage / generated / composed are where multi-source assembly falls apart — engineer continuity across them:
+
+- **One look across every source.** Apply the `style_kit` so a cut from real footage → a generated shot → a composed card does not read as three videos: one type system + palette on every composed layer, one caption style throughout, matched aspect / fps, tonal proximity (a shared LUT is the unifier when available; `video-craft` §4).
+- **Audio is the through-line that hides the visual seam.** One narration voice; a continuous music bed UNDER the cuts (do not restart it per segment); duck consistently (`video-craft` §7). The ear's continuity carries the eye across a source change — a reveal may drop music, but the bed bridges the cut.
+- **Rhythm over a mixed cut.** Alternate motion vs. static and source types for momentum — do not stack three composed cards or three talking-head shots in a row (that is the repetition / slideshow smell, `video-craft` §3, §12). Vary holds.
+- **Cut on a content change, not just plan order.** A hard cut on a beat / word change is invisible and professional; a crossfade signals a gentle topic shift (`video-craft` §5).
+- **Don't bury the hero.** On a `source_led` piece, composed lower-thirds and captions FRAME the footage — they never cover its subject / face (`video-craft` §6).
+- **Apply the editing cut craft ACROSS the seams.** The cut mechanics live in `stage-edit` → "Cut craft" (best sub-window, ≤ 4 transitions, L/J-cut sound bridges, handles / no freeze-frame, adjacent-diversity, a reason per cut) — apply them at every junction between sources, since the footage → generated → composed seams are exactly where a mixed cut betrays itself.
+
+## Step 3 — Idempotent resume
+
+The plan plus project-scoped production control is the checkpoint. On a re-run, call `production.status`, skip any segment already `status:"done"` with a present `produced_path`, and let the host return `reused` for a completed generation transaction. Skip assembly tiers whose output already exists and is newer than its inputs. Never infer that a missing chat bubble means a billable segment should run again.
+
+For a partial child failure or a later user revision, preserve every unaffected
+`done` segment and its transaction/source evidence. Reset only the changed or
+failed segment plus assembly tiers derived from it; never regenerate,
+retranscribe, or re-compose sibling segments merely to rebuild the complete
+review artifact. The rebuilt assembly is a new immutable candidate and must
+include all current child outputs. Any earlier Final video confirmation is
+stale for that assembly candidate.
+
+Non-user recovery must advance the parent workflow, not end at the repaired
+child. In the same turn that the affected child becomes valid, rebuild every
+derived parent assembly tier, run parent QA, publish the complete current draft
+and its exact path, and open the single Final video confirmation bound to that
+assembly candidate. Do not return only a child artifact, a recovery summary, or
+an instruction to resume assembly later.
+
+If recovery cannot continue safely, present the latest assembled draft when
+one exists, the completed child artifacts, the exact failed segment and
+finding, and the next actionable option. A partial failure is not permission
+to hide successful work or ask for a generic technical recovery decision.
+
+A recovery description is not a recovery action. When a child fails a free
+validation such as inspect, the executable path must include a concrete
+mutation of that child's canonical input (or the child operation that produces
+the corrected artifact) before the validation is repeated. Never list only the
+same inspect/render call after saying "repair first"; that is an unchanged
+retry and can loop forever. Once the changed child passes, rebuild the parent
+assembly from the preserved completed children.
+
+## Step 4 — QA report, then gate D
+
+Before showing the draft, run the QA pass and write `project/render_report.json` with these sections:
+
+- **technical_probe** — `stage-edit edit_video --op probe` the draft (real duration / resolution / fps / audio present); confirm it matches the plan's aspect + total.
+- **promise_preservation** — run `"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op promise_check --plan project/plan.json --probe-produced`. At gate D this probes each primary segment's `produced_path` and computes the REAL primary-track footage/generated-video ratio vs. `motion_min_ratio` plus the `source_required` invariant. A `compose_led` plan uses a zero real-motion floor because native composition QA owns its HTML animation contract. Missing/unreadable produced media or a fail means **"slideshow / promise broken" — do not deliver**. Send it back (below). Do not eyeball this; let the numbers decide.
+- **visual_spotcheck** — extract ~4 frames across the draft (`stage-edit edit_video --op extract_frame`) and read them for upside-down / garbled-caption / empty / wrong-product frames. Read them yourself if you are multimodal; if you cannot see images, record the spot-check as `unverified` and proceed — do not invent what the frames show.
+- **audio_spotcheck** — the `op="normalize_loudness"` measured loudness numbers + the narration coverage result from step 2 (uncovered tail / silent lead-in).
+- **transcript_comparison** (when there is narration) — optionally transcribe the draft with `video_studio` `op: "speech.transcribe"`, then confirm the spoken words match the planned narration lines.
+
+Each section carries `pass` / `warn` / `fail` + a one-line reason. Then present the draft `[video]` + the report's headline findings at **gate D**.
+
+On approve → finalize `project/render/video.mp4` (loudness / captions only; never re-synthesize a talking-head voice). On revise → redo only the affected segment(s) and re-assemble.
+
+## Send-back (self-correction on a QA fail)
+
+A QA `fail` does not go to the user as "here's a broken video". Diagnose which segment(s) caused it and redo ONLY those, then re-assemble and re-run QA:
+
+- promise_preservation fail (slideshow) → the static composed segments are too long / the motion segments too short. Rebalance segment durations or convert a static beat to footage, re-assemble.
+- visual_spotcheck fail (bad frame) → re-produce that one segment (re-trim / re-compose / re-generate), not the whole video.
+- audio fail (uncovered tail) → re-time or extend the narration / trim the tail.
+
+Bound repetition, not recovery: allow at most **2** send-back rounds for the same failing check and unchanged recovery strategy. If it still fails, preserve the evidence, stop repeating that strategy, and choose a materially different localized repair or return to the earliest affected non-billable step. Do not create a technical confirmation form. If every safe non-billable recovery conflicts with the signed plan, present the concrete conflict at the normal final-video review; a direct user reply may revise the affected scope. A signed-plan change uses the single plan-amendment review, and a new billable provider call uses the paid-generation review. Never loop forever or quietly ship a known-failing draft.
+
+## Rules
+
+- Walk the approved plan; if assembly reveals the plan is wrong, surface it and re-gate — do not silently re-plan.
+- Write `produced_path` + `status` back per segment as you go (resumability + the QA pass depend on it).
+- One output file is the deliverable; `cuts/` and `parts/` are intermediates.
+- **Narration is added exactly ONCE — in the mix tier, never baked into a compose render.** Compose segments (including a full-video composition used as the primary track) render SILENT (no narration `<audio>`); the assembler mixes narration via `stage-edit edit_video --op mix` with `audio_segments` placed per line. The mix's default `on_existing_audio:"reject"` enforces this — an `E_EDIT_BASE_HAS_AUDIO` error is the signal a segment wrongly baked audio in.
+- **No ad-hoc ffmpeg fallbacks for captions.** Caption burn-in is a low-freedom operation owned by `stage-edit edit_video --op burnsubs`; a failed burnsubs call is a tool/runtime blocker, not permission to invent a custom subtitles/drawtext/PNG-overlay command.
+
+## Boundary / non-goals
+
+This skill assembles an already-approved plan. It does not ingest or decide the plan (`stage-plan`), and it delegates the actual production of each segment to the compose / generate / edit / consistency skills rather than re-deriving their craft here.

+description_en: Authoring knowledge for Orkas HTML video compositions — how to write an index.html composition, drive animation from a timeline, declare canvas + duration, then render to mp4; core skill for explainer/animation/motion-graphics/caption work.
+---
+
+# stage-compose
+
+Author an Orkas HTML composition and turn it into video. In Orkas, lint,
+inspect, snapshot, draft, and export run through built-in `video_studio`.
+
+Apply `frontend-design` before writing `manifest.art_direction`. When the user
+provides a reference image/video, DESIGN.md, brand guide, screenshot, design
+notes, or named style, apply `design-system-importer` to create intent-bound
+media constraints and compact tokens. After snapshot, apply
+`composition-design-review` yourself as an advisory frame checklist; it never
+replaces native QA or creates a gate.
+
+All COMPOSE stops and authorization transitions belong to `gate-control`. This
+Skill supplies the manifest, contact sheet, draft, QA evidence, and readiness;
+pass those facts to `gate-control` rather than restating approval policy.
+
+## No-runtime advisory package
+
+When production tools cannot run, follow `gate-control`'s complete unexecuted-
+package protocol and read
+[no-runtime-package.md](references/no-runtime-package.md). Read it only on that
+branch; ordinary runtime work never needs it.
+
+## QA response kernel
+
+Every QA failure or recovery handoff carries the current reviewable artifact
+package, not only a reason: returned `current_candidate`, contact sheet or
+sampled frames, failed draft when present, and `findings_path`/inline findings.
+Label it current but unapproved, state the bounded repair and next cheap check,
+and omit fields not returned. If `review_package.presentation_required:true`,
+show `primary_artifact`, summarize `conclusion`, and keep other paths as evidence.
+With no media, show the returned manifest or authored HTML.
+
+Ask only for a real creative/cost choice, with concrete options derived from the
+artifact. Do not expose native error ids, Gate labels, repair budgets,
+signatures, or schema jargon. Translate a result into: what needs work, what
+remains safe, and the concrete repair/next check. In Chinese, say `生成旁白音频`,
+`将旁白音频加入视频`, or `旁白音频生成失败`, never `旁白物化`.
+
+Top-level continuation fields outrank prose errors:
+
+- `next_step_owner:agent` plus `execution.continue_in_current_turn:true` means
+  mutate the named file, retry, and continue in this turn.
+- `next_step_owner:user` requires the artifact and concrete choices now.
+- `next_step_owner:external` stops safely at the preserved artifact without
+  claiming automatic recovery.
+
+Fatal inspect blocks snapshot/draft/preview until repaired. A successful inspect
+with visual review allowed goes to snapshot before editing, so repairs have frame
+evidence. Before showing a passing snapshot, inspect the complete returned frame
+set economically, batch visible blockers, repair affected scenes, then rerun
+inspect + snapshot. A semantic failure stays visible but unapproved and must not
+retry unchanged input. An exhausted visual-QA cycle shows evidence and native
+options, then waits; no recovery operation exists.
+
+A narration retime moves all scene windows. When materialization returns
+`scaffold_retimed:true`, adjust each shifted scene's tweens from its new window
+before inspect/snapshot; do not drop a silent designed beat.
+
+A passing snapshot ends the turn until go-ahead for its visual identity. Show
+the complete frame set and stop; do not draft in that turn. Visible changes make
+a new identity and require one changed complete preview. Narration/audio-only
+work inherits prior preview when scene windows and pixels are unchanged.
+
+For detailed failure classification, repair causes, and bounded retry behavior,
+read [qa-and-repair.md](references/qa-and-repair.md) only after inspect,
+snapshot, or draft actually reports a failure/recovery branch.
+
+## Post-gate revisions
+
+On every gate submission or post-gate edit, use `gate-control` and its resolver
+before production calls. Styling-only HTML/CSS/SVG/layout/motion/palette/assets
+is `visual_only`. Signed delivery, approved copy, narration, timing, language,
+source mappings, roles, or narration intent is `gate_b_payload`.
+
+After a draft/final `visual_only` edit, recapture and show the changed complete
+frame set, wait for go-ahead, then draft the complete composition as one mp4.
+Approved export re-encodes the same whole composition at delivery quality. The
+new draft reopens final-video confirmation; do not imply only one scene can be
+encoded or skip whole-composition QA.
+
+In other words, `composition.draft` re-encodes the complete composition as one mp4;
+export is not a scene-only shortcut.
+
+## Fast COMPOSE runbook
+
+1. Read this installed root once per conversation; re-read only when runtime
+   reports an updated installation. Read an existing canonical manifest. Apply
+   `frontend-design`; apply `design-system-importer` only for a concrete style
+   source; apply `composition-design-review` only after snapshot.
+2. Stop for direction before writing any manifest, narration, or art direction.
+3. The plan is only
+   `project/composition/composition-manifest.json`: duration, language, audio
+   ownership, scenes, approved copy, narration, and art direction. No shotlist,
+   script, or second structural contract. Before authoring it, read
+   [manifest-and-authoring.md](references/manifest-and-authoring.md), which owns
+   schema, scaffold, language, art direction, and offline authoring rules.
+4. For standalone narration, call `speech.capabilities`, select a returned
+   locale-compatible `route_ref` + `voice_ref`, write exact intent, then run the
+   free `composition.check_narration_fit`. Open the plan stop only when
+   `gate_b_ready:true`.
+5. On every new/resumed production turn, call `composition.status`. Reconcile
+   file/state disagreement through `gate-control`. Plan identity is normalized
+   approved intent, not raw manifest hash; implementation-only art direction,
+   formatting, HTML/CSS/SVG/motion makes a new candidate without reopening plan.
+   Once current, call `composition.doctor` once that turn, fix missing required
+   capabilities, then call `composition.prepare`.
+6. For standalone speech after prepare, read
+   [narration.md](references/narration.md) before
+   `composition.materialize_narration`. AUTO child composition stays silent
+   because its assembler owns narration. Narration failure blocks complete
+   delivery, not visual authoring/inspect/snapshot.
+7. Author visual DOM/CSS/SVG and deterministic tweens in the scaffold. Build the
+   resolved visible frame first, then animate into it. Keep each scene's tweens
+   inside its `ORKAS-SCENE-MOTION-BEGIN/END` block and target only that section;
+   cross-scene/outside code may render but loses attribution and incremental
+   reuse.
+8. Run `composition.inspect`. Repair all independent blocking findings together,
+   starting with manifest/art direction, then HTML. Advisories are judged, not
+   loop-repaired. Retry only after canonical signature changes, with at most two
+   materially different passes across inspect/snapshot. Native runtime owns QA:
+   never install/start a browser, HTTP server, watcher, Puppeteer, Playwright, or
+   headless Chrome.
+9. Treat each `current_candidate.revision_id` as immutable. Edits create a new
+   candidate and preserve accepted deltas. Publish only current locators, never
+   private content-addressed storage paths or `first_frame` as the whole preview.
+10. Preview before rendering when duration >=20s or scenes >=3, and for shorter
+    work with dense text, complex SVG/GSAP, many supplied assets, narration
+    complexity, or prior draft failure. Skip only genuinely short/simple work.
+11. Before snapshot/draft/export, read
+    [render-and-preview.md](references/render-and-preview.md). Run inspect +
+    snapshot, use contact sheet as the complete index, open full scale only the
+    cover, QA-named frames, or risky cells, then batch repairs. Pass readiness or
+    errors and later user decisions to `gate-control`.
+12. Run `composition.draft`. Structural failures repair the highest source—
+    manifest, art direction/mapped content, then HTML—and never retry the same
+    signature. Preserve render/audio/frame QA. A successful draft is not
+    terminal: when `gate_d_ready:true`, freeze inputs and show the existing mp4
+    plus QA headline through `gate-control`.
+
+The default path is: direction -> candidate manifest -> free narration fit ->
+one plan confirmation -> doctor -> native scaffold -> optional narration ->
+VisualDirectionV1/resolved-frame authoring -> inspect/snapshot -> preview ->
+draft -> final confirmation -> export. `VideoProductionStateV1` is durable state;
+call status/reconcile rather than inventing or skipping a stage. Never write or
+compile `spec.json` or use fixed visual templates.
+
+## Render-contract quality invariants
+
+- **Render something at t=0 in every composition, including AUTO segments.** A
+  scene or its title/hero beginning at `opacity:0` produces
+  `EMPTY_HOOK_FRAME`, `EXPECTED_SCENE_NOT_VISIBLE`, or
+  `HOOK_PROMISE_NOT_VISIBLE`. Author the resolved visible frame first. A user-
+  requested fade from black is the exception.
+- **Delivered frame 0 is a dedicated cover:** one approved headline, dominant
+  `data-role="visual" data-cover-hero`, and at least two concrete visible
+  `content_signals` (`data-cover-signal` when needed). A headline restatement is
+  not a second signal.
+- **Give QA semantic hooks:** `data-scene-id` on clips and
+  `data-role="title|body|label|caption|visual"` on major groups. Keep readable
+  copy as real HTML text.
+- **Never position a tween at a literal second.** Leave scene visibility to the
+  scaffold and position authored motion from `S("<scene-id>")`/`D("<scene-id>")`.
+  Retime can shift every window; inspect reports
+  `AUTHORED_ABSOLUTE_TIMELINE_SECONDS` with the replacement expression.
+
+Native QA blocks small/unsafe text, overflow, overlap, occlusion, clipping, and
+low contrast. Thin art direction, repeated grammar, one-note palette, and
+decorative complexity remain advisory unless they break an approved visible
+promise.
+
+## Director judgment
+
+- One concept per visual chapter; concrete before abstract.
+- Choose one subject-derived signature device and spend distinctiveness there.
+- Render exact stats/names/CTAs as real text, never AI-image text.
+- Build to narration words and hold a resolved chart/scene before moving on.
+- Vary scene types; no three near-identical layouts in a row.
+- Ordinary subtitles are caption-track data owned by assembly. Only decorative
+  kinetic captioning may be baked into the composition, and the user must know
+  it is not separately editable.
+
+## Constraints
+
+- Deterministic only: no real-time timers, network runtime behavior, or unfixed
+  randomness; the renderer seeks discrete frames.
+- Keep all assets inside the composition directory.
+- This Skill authors/renders compositions; routing chooses the line and other
+  Skills generate AI footage.

+# Manifest and composition authoring
+
+## Canonical composition manifest
+
+Write `project/composition/composition-manifest.json` before
+`composition.prepare`. It is the only structural source of truth; never
+duplicate canvas, duration, scenes, or audio ownership in another contract.
+
+It owns canvas, immutable target duration, fps, video language, scene windows,
+complete approved `source_shots`, semantic roles, narration intent, audio
+ownership, and `art_direction`. Declare captions with
+`composition.caption_mode`; absent means none. Standalone narrated work stores
+complete candidate words in each `narration_text` and pre-production audio as
+`owner:"none"`, `tracks:[]`, plus selected `narration_intent`. Visual/SFX-only
+work keeps narration empty and says at plan review that no voiceover is made.
+
+```json
+{
+  "schema_version": 2,
+  "composition": {
+    "id": "main", "width": 1920, "height": 1080,
+    "duration": 60, "target_duration": 60, "fps": 30, "language": "en"
+  },
+  "scenes": [{
+    "id": "hook", "start": 0, "duration": 5,
+    "approved_copy": ["Orkas 1.5.0"],
+    "narration_text": "A concise line for this exact window.",
+    "narration_refs": ["n01"], "source_shots": ["s01"],
+    "roles": ["title", "visual"]
+  }],
+  "audio": {
+    "owner": "none", "tracks": [],
+    "narration_intent": {
+      "route_ref": "managed:orkas-voice",
+      "voice_ref": "<copy exactly from speech.capabilities>",
+      "display_name": "Vivi", "language": "zh-CN", "speed": 1
+    }
+  }
+}
+```
+
+This is planned pre-production form. Plan approval signs `narration_intent`;
+`composition.materialize_narration` reads it without execution-time overrides,
+changes owner to `composition`, writes the track, preserves intent, and replaces
+estimated with measured timing. Schema version 1 is legacy recovery only.
+
+Every scene uses numeric `start` and `duration`, never `start_s`/`duration_s`.
+`source_shots` names approved beats and narration fields align voice. With no
+shotlist alias, a `source_shots` change alters approved intent. AUTO segment
+audio owner is `assembler` when it carries narration and must render silent.
+
+Materialization creates `project/composition/narration-map.json`. For external
+narration only, provide a compatible map before draft:
+
+```json
+{"lines":[{"id":"n01","scene_id":"hook","start":0,"end":3.2,"text":"Meet Orkas 1.5.0."}]}
+```
+
+Use matching `narration_ref`; timed media refs are valid when the map line has
+matching scene or time. Without a map, every narrated scene needs inline
+narration plus numeric timing or draft QA blocks final review.
+
+## Native scaffold
+
+`composition.prepare` derives root canvas/timing, scene clips, semantic ids,
+declarative audio, local GSAP vendor, paused master timeline, and registration.
+Do not hand-create or replace protected fields. After authoring, use
+`composition.reconcile` to update only protected root/clip/audio metadata while
+preserving DOM/CSS/SVG; deliberately update custom tween timing after retime.
+
+Author visual DOM inside generated scene roots and motion on
+`window.__ORKAS_COMPOSITION_TIMELINE__`. Never call media `play`, `pause`, set
+`currentTime`, or create a wall-clock/unregistered timeline.
+
+## Authoring patterns
+
+- Canvas: manifest declares 16:9 = 1920×1080, 9:16 = 1080×1920, or 1:1 =
+  1080×1080 once; scaffold mirrors it.
+- Scenes: one canonical window per beat; do not retime clip attributes separately.
+- Text: safe padding, large contrast, one idea per scene.
+- Assets: relative paths inside composition dir, e.g. `./assets/shot1.png`.
+- Timing: every tween begins from scaffold `S("<scene-id>")`, never a literal.
+- Prefer inline SVG for diagrams, connectors, nodes, charts, paths, icon-like
+  marks, and geometry; keep prose in HTML text.
+- Use GSAP only for time-based motion and animate SVG groups or a few HTML
+  containers; avoid dozens of absolute card/line nodes.
+- No CDN scripts, remote fonts/images/CSS, or other remote runtime resources.
+  Copy needed assets locally. Native prepares offline GSAP; never patch it.
+
+## Art direction before HTML
+
+Write `art_direction` inside the manifest. It is an internal visual contract,
+not another artifact or user gate. `frontend-design` owns its field list and
+pre-code anti-template check: name the first generic move rejected and the brief-
+specific replacement. Reject lazy defaults such as purple/blue neon, glowing
+black circles, centered equal-weight layouts, identical cards, decorative
+emoji/icons, tiny badges, dashboard fragments, pure black/white, and web-scale
+type. When `style_source` exists, name what was adapted, simplified, and not
+copied.
+
+Fields come from `frontend-design`: `aesthetic`, `visual_direction`
+(`VisualDirectionV1`), `cover`, `typography_tokens`, `anti_template_check`,
+`color_tokens`, and per-scene `depth_layers`/`motion_verbs`. This line adds:
+
+- `style_source` from `design-system-importer` for a concrete external source;
+  omit when none.
+- `references` + `reference_fidelity` for every concrete reference image/video
+  and only then. Unspecified reference defaults to
+  `intent:guide,intent_basis:inferred`.
+
+## Video language and copy
+
+User UI language controls chat, review summaries, and explanations. Video
+language comes from VideoStudio input and `manifest.composition.language`; it
+controls plan/script, approved copy, narration, captions, titles, subtitles,
+CTAs, and visible HTML. Use the language locked by `gate-control`, do not infer a
+second default, and do not add unapproved bilingual or decorative English copy.
+Proper nouns, product/API names, code, and approved source text may remain.
+
+Preserve approved English casing: natural title/sentence case. Existing all caps
+may remain only when exact approved/source casing, and only for a short label,
+acronym, or code. Never use broad `text-transform:uppercase` for model-authored
+mood. Typography/layout budgets bind badges, pills, labels, captions, cards,
+nodes, and microcopy. Shorten safely without changing meaning; ask only if
+meaning would change.
+
+## Unified preflight
+
+Preflight blocks missing/invalid/overlapping manifest; incomplete art direction,
+cover, VisualDirectionV1, motion/variation/depth contracts; missing reference
+fidelity/source; root/scene/audio drift; timing outside duration; missing
+declared copy; missing/outside/absolute/remote assets; GSAP without local vendor
+and registered paused timeline; and imperative media control. Repeated layout
+grammar or one-note palette warns without blocking.

+<!-- stage-compose reference. Read this only when the composition actually
+speaks: a visual-only or SFX-only piece never needs it, and a COMPOSE segment
+inside an AUTO production renders silent because the assembler owns the voice. -->
+
+# Narration / audio track
+
+**WHO OWNS NARRATION — decide this first:**
+- **Standalone COMPOSE deliverable** (the composition IS the finished video, no assemble step): plan with `audio.owner="none"`, then let `composition.materialize_narration` change the validated manifest to `audio.owner="composition"` and generate the `<audio>` scaffold element that the renderer muxes.
+- **Composition is a SEGMENT in an AUTO/assemble pipeline** (the assembler will mix narration in its mix tier — `stage-assemble` step 3): render this composition **SILENT — do NOT add a narration `<audio>` track**. If you bake narration in here AND the assembler mixes it, narration is added twice and you get two overlapping, drifting voices (the "two voices" defect). The mix step now refuses a non-silent base (`E_EDIT_BASE_HAS_AUDIO`) precisely to catch this. Background music inside the composition is also best left to the assembler so it can duck consistently under the one narration.
+
+To give a STANDALONE explainer a voiceover: approve its words at Gate B, write those exact words as scene `narration_text`, prepare the planned manifest, then call `composition.materialize_narration`. Do not call generic `generate_speech`, manually patch the resulting track, instantiate `Audio`, call `.play()`/`.pause()`, assign `.currentTime`, or use a GSAP callback to control media.
+
+```json
+"audio": {
+  "owner": "composition",
+  "tracks": [
+    { "id": "narration", "kind": "narration", "src": "assets/narration.mp3", "start": 0, "duration": 60, "volume": 1 }
+  ]
+}
+```
+
+- `composition.target_duration` remains the Gate B delivery target. Native timing reserves every explicitly silent opening or ending scene at its authored duration, then uses the remaining delivery time as the narration target. The accepted narration band is that narration target plus or minus `max(target * 5%, 5s)`. A shorter fitting read may leave a visual hold; when measured speech plus reserved silence exceeds the delivery target, `composition.duration` expands so neither speech nor the silent beat is truncated.
+- `composition.materialize_narration` derives that narration target from the approved manifest automatically. Its free mixed-language preflight counts CJK characters, Latin words/initialisms, numbers/versions, punctuation pauses, and speed. `E_TTS_TEXT_TOO_LONG` or `E_TTS_TEXT_TOO_SHORT` returns before billing and requires a timing-focused script revision instead of silently changing approved words.
+- Do not call generic speech synthesis or supply an implicit, guessed, or whole-delivery narration target. Keep explicit silence in the manifest and let `composition.check_narration_fit` / `composition.materialize_narration` derive the speech budget from the approved delivery timeline.
+- After synthesis, the operation records `measured_duration_sec`, the resolved band, `narration-map.json`, and the transaction in the durable ledger. If speech is outside the band, revise the synchronized narration copies to `suggested_units`, run the free fit check, then continue from `composition.prepare` when it returns `approval_inherited:true`. The timing episode permits one automatic revised synthesis across the changed text hash. If that attempt is still outside the band, end the turn with the returned user choices; do not synthesize again without a new user decision.
+- When the user chooses another narration revision, that reply authorizes exactly one additional synthesis after the free fit check. When the user chooses to proceed, call `composition.materialize_narration` with the same current-turn decision evidence so the waiver is recorded and the composition is retimed to the complete current audio. A structural change or narration rewrite beyond the authorized edit scope still requires a new Gate B approval.
+- If `composition.materialize_narration` fails for another reason, never silently continue: respect its production state and error code, then either fix the approved narration input or explicitly proceed silent with that stated at the gate. Draft QA flags a contract that declares narration while the composition has no audio (`NARRATION_DECLARED_BUT_SILENT`) — do not present such a draft as if it were complete.
+- Narration output is fixed at `project/composition/assets/narration.mp3`, keeping the composition self-contained and making successful synthesis idempotent across resumed Agent turns.
+- Add background music only after narration timing is materialized, keep its volume low (e.g. 0.2), update the manifest track, then call `composition.reconcile` so protected audio markup stays synchronized without replacing visual HTML. Do not make music part of narration duration fitting.
+- Keep narration audio inside the composition dir so the render is self-contained.
+- **Talking-head caveat:** when this composition is being overlaid onto AI-generated talking-head footage that already has **lip-synced built-in speech** (generation line), do NOT add a narration `<audio>` track. The renderer's muxed audio replaces the clip's own voice, so a synthesized narration would desync from the mouth. Use this composition for captions / lower-thirds only and let the clip's built-in audio stand (background music at low volume is fine; spoken narration is not).

+
+- For a general-audience explainer, connect every abstract trend to at least one concrete everyday use, consequence, or decision. Routine direction questions do not justify withholding the complete package.
+- If the plan needs no external media, explicitly record the visuals as self-authored HTML/CSS/SVG in the asset ledger; for any later replacement, require source, creator/license, permitted use, and local filename.
+- Before ending the package, include a separate target-export block (container, pixel dimensions, frame rate, video/audio codec intent) and a checkable final-QA list covering duration tolerance, nonblank first frame and hook timing, safe-zone/readability, caption timing, loudness and music ducking, blank/frozen-frame sampling, encoding validity, and playback of the intended final file.
+
+AUTO child compositions are the one Gate B inheritance path. Their local `composition-manifest.json` is derived by the host from the signed parent segment's `composition_plan` — do not hand-author it.

+# QA and repair detail
+
+## Failure classification
+
+- Fatal inspect blocker: repair runtime/structural contract and rerun inspect.
+  Do not snapshot, draft, or present preview before fatal count reaches zero.
+- Visual review required: if inspect is structurally successful and capture is
+  allowed, snapshot before editing so the repair loop has frame evidence. Visual
+  blockers may produce frames but do not reach preview/draft; advisories continue.
+- Passing snapshot: inspect the returned frame set as directed by the root,
+  batch visible blockers, repair affected scenes, rerun inspect + snapshot, and
+  never present/approve stale evidence.
+- Snapshot semantic failure: preserve candidate, `preview_qa`, and
+  `frame_evidence` as unapproved. Change implicated signature before retry. Use a
+  materially different evidence-based repair while passes remain.
+- Exhausted visual QA: show current evidence/findings plus returned redirect,
+  simplify, waive, or another-attempt choices and end. A later real reply grants
+  the next cycle; no restart/recovery operation exists.
+
+Each repair has one bounded target and one next operation. Native passing
+snapshot may later open preview; prohibitions persist while blocker/stale
+signature remains.
+
+## Artifact-validation recovery
+
+An “approval validation” error is not a bad user confirmation. Use returned
+`artifact_issues` to distinguish missing file, invalid JSON, or invalid manifest
+field. If `automatic_recovery_expected:true`, do not stop after promising a
+repair: read named artifacts, repair only structure preserving confirmed meaning,
+retry the returned operation in this turn, and continue. Ask again only if repair
+changes approved script, duration, delivery, or creative intent.
+
+Call music, captions, and narration implemented only when both manifest and
+rendered artifact contain them. Required narration blocks complete draft/final,
+not visual inspection or editing.
+
+## Inspect/snapshot cycle
+
+Repair all independent findings in one pass. A failed inspect may still have
+runtime measurements when `runtime_probe_ran:true`; use them now. Advisory
+warnings such as casing, cover composition, thesis specificity, or reference
+ambition are judged against frames and never loop-repaired. Retry only after
+manifest/HTML signature changes, with at most two distinct strategies across the
+shared inspect/snapshot cycle. `E_INSPECT_RETRY_NO_CHANGE` blocks only unchanged
+probe. A repeated already-passing signature returns cached contact sheet and
+preview revision; publish them and do not rerun.
+
+Treat content-addressed snapshots as storage evidence, never edit targets. A
+failed inspect/snapshot/draft still returns the candidate; present available
+contact sheet/frame/draft/findings as current but unapproved while continuing.
+Preserve cumulative user deltas across revisions. After a changed signature,
+rerun whole-composition inspect/snapshot; use contact sheet as full index and
+drill into QA-named or visibly risky frames.
+
+## Draft repair budget
+
+After failing draft, repair once and rerun; a second pass is allowed only when
+remaining blockers are fewer and localized. `E_REPAIR_BUDGET_EXCEEDED` blocks
+another draft for the same signature, not editing, reconcile, lint, inspect, or
+a later changed-signature draft. Make a materially different localized edit and
+cheap checks. Regenerate `index.html` only for structural failure. If only
+advisories remain and draft is `ok:true`, present mp4 plus QA notes instead of
+looping. This internal non-billable recovery creates no user gate.
+
+## Repair causes, not symptoms
+
+- `FONT_TOO_SMALL`: reduce density, shorten copy, enlarge/reflow, or move labels
+  out of small shapes; do not globally scale fonts into overflow.
+- `missing_timeline_registry`, `gsap_timeline_not_registered`: register paused
+  GSAP on `window.__timelines[compositionId]` using exact root id.
+- `timed_element_missing_clip_class`, `root_composition_missing_data_start`,
+  `media_missing_data_start`, `imperative_media_control`: renderer owns timing
+  through `data-start`, `data-duration`, `.clip`, and media attributes; never
+  custom play/pause/currentTime, timers, or `seekTo`.
+- `text_occluded`, `text_box_overflow`, `content_overlap`: restructure scene or
+  regenerate from contract boxes; numeric nudges are not a fix.
+- `STATIC_FRAME_RUN`: fix timeline registration, clip timing, or scene variation;
+  never deliver a draft whose sampled scenes repeat.
+
+Repair manifest, art direction, mapped content, or visual HTML directly; never
+introduce `spec.json` as workaround.

+## How to call the render path
+
+```json
+{"op":"composition.draft","composition_dir":"project/composition","output_path":"project/render/draft.mp4","quality":"draft","report_path":"project/render/draft-report.json","findings_path":"project/composition/qa/inspect.json"}
+```
+
+Draft runs lint and inspect before rendering, then reports contract/source
+alignment, media probe, loudness, audio timing, video-frame QA, render
+throughput, and optional visual-regression status, writing a contact sheet and
+per-sample evidence frames. Lint blocks render-contract errors — unregistered
+timelines, missing clip timing, invalid root timing, imperative media control.
+Semantic defects on readable content (small text, overflow, occlusion,
+overlap, low contrast, safe-area violations, primary elements outside canvas)
+are blockers; decorative out-of-canvas accents and palette/variety findings are
+advisory. Video QA samples frame 0 and each scene start/mid, so an empty hook
+or blank scene boundary blocks Gate D; a frozen sampled run blocks earlier, at
+the visual preview, because a motionless stretch is invisible in a contact
+sheet. With `findings_path` the full payload goes to disk — read it only when
+the summary points at a specific issue. Stop and repair when
+`draft_disposition.blocking_error_count > 0` or any of those QA phases fails.
+
+Raw `composition.render` is not exposed: it would bypass video QA. Give the
+frozen draft signature and the user's submission to `gate-control`; only an
+export transition it returns may call the QA-gated high export:
+
+```json
+{"op":"composition.export","composition_dir":"project/composition","output_path":"project/render/final.mp4","report_path":"project/render/final-report.json"}
+```
+
+Export is allowed only while the inputs still match the successful draft and
+the native approval is current. It reruns render, media and frame QA at the
+delivery quality (high by default), writes the frame-0 cover beside the video
+as `<video-name>-cover.png`, and returns `next_action:"deliver_final"`; the
+final response must include the video and mention the cover, or a clear
+blocker. When the user explicitly accepts a faster lower-quality delivery,
+pass `quality:"standard"` or `quality:"draft"` on the export call — a
+draft-quality export reuses the approved draft's cached render and finishes in
+seconds, while high re-captures every frame at 30fps and can take tens of
+minutes on a long video. Never downgrade quality on your own; the result's
+`render_settings.quality` records what was delivered. Call it once and let the host
+pick the highest safe fps; a `render_profile.degraded_fps` fallback is internal execution with `confirmation_required:false`, and continues straight to delivery. Never modify `composition-manifest.json`, call `composition.reconcile`/`composition.draft`/`composition.snapshot`, or reopen Preview/Gate D because the host lowered fps or another non-content encoder setting. Set
+`strict_render_settings:true` only when the user required exact technical
+settings; if that leaves no safe fallback, report the constraint as a blocker
+rather than inventing another approval gate.
+
+## HTML Preview Gate
+
+A cost-control gate, not a creative milestone, and only for COMPOSE: it exists
+so visual rework happens before an expensive mp4 rerender. **Preview first (hard gate)** when duration >= 20s or scene count >= 3 — the host enforces it, and `composition.draft` rejects a missing, stale, failed, or not-yet-approved preview. Runbook step 6 owns the judgement calls below that threshold.
+
+```json
+{"op":"composition.inspect","composition_dir":"project/composition","findings_path":"project/composition/qa/inspect-preview.json"}
+{"op":"composition.snapshot","composition_dir":"project/composition","output_path":"project/composition/preview/first-frame.png"}
+```
+
+`output_path` stays the first-frame PNG for compatibility; the result also
+carries the contact sheet and semantic evidence for every scene. Run the
+economical frame pass from the stage-compose runbook, repair all blockers
+together, and rerun inspect + snapshot — a changed snapshot requires
+re-checking its full new frame set. When the frames read well, hand
+`gate-control` the published contact sheet, the `index.html` path, and a
+compact readiness note: why preview applied (duration / scene count /
+complexity / prior failure), the inspect headline, and what approval means
+(render the mp4 draft next). Then obey the transition it returns. Keep preview
+revisions lightweight; do not synthesize new narration or render mp4 while the
+preview artifact is still under review.
+
+Use `update_visual_baseline:true` only when the user or an explicit project
+workflow promotes an approved preview to a golden baseline; later snapshots
+compare matching frames and report changes as advisories, never as an automatic
+rerender loop.
+
+The preview does not replace the mp4 draft — it cannot validate audio muxing,
+final encoded quality, sampled-frame video QA, or exact narration pacing. After
+approval, always run `composition.draft` and open Gate D with the video.

+---
+
+# stage-consistency
+
+How to keep characters, settings, and style **consistent across many generated shots** (and across scenes in a long story). This is the depth layer on top of the generation line: the generation line makes clips; this skill makes the SAME character look the same in every clip. Host-neutral — describe the outcome; use generic built-in capabilities for generation/retrieval (Orkas: `generate_image`, `generate_video`, `kb_*`) and VideoStudio skill scripts for media extraction (`stage-edit edit_video --op extract_frame` via `bin/run-skill.cjs`).
+
+## 1. Character bible (extract once, lock the look)
+
+From the script/idea, extract every recurring character into `project/characters/bible.json`. For each character separate:
+
+- **static features** — the *immutable* visual identity: face, hair, body shape, ethnicity, age range. These NEVER change shot-to-shot.
+- **dynamic features** — changeable: clothing, accessories, expression.
+- a single **canonical name** (merge every alias/pronoun for the same person to one id).
+
+```json
+{
+  "alice": {
+    "static": "early-20s East-Asian woman, oval face, long black hair, slim build",
+    "dynamic": "green linen dress, small gold earrings",
+    "portrait": { "front": "characters/alice_front.png", "side": "characters/alice_side.png", "back": "characters/alice_back.png" }
+  }
+}
+```
+
+## 2. Portrait anchor (generate once, then LOCK)
+
+For each character, plan ONE **front portrait** as its own signed `media_kind:"image"` EDL segment, then generate it with `generate_image` using that segment id. **This is the anchor — never regenerate it.** Any separately generated side/back view is another explicit Gate C segment; otherwise derive views without a new hosted generation. Save paths into the bible.
+
+- **Cameo** (the user uploads a photo to BE a character): use that photo AS the front portrait — skip generation for that character. Everything downstream references it.
+
+## 3. Storyboard with character binding
+
+Decompose the script into shots. Each shot records:
+
+- which characters are visible (and at what camera angle — front / side / back),
+- a first-frame description and the motion,
+- **describe motion by VISUAL FEATURES, not names** — write "the figure in the green dress turns to the figure in the blue shirt", NOT "Alice turns to Bob". (Generators ground on appearance, not names.)
+
+## 4. Per-shot reference selection (the core consistency mechanism)
+
+For each shot, before generating it, assemble the reference images and bind them explicitly:
+
+1. **Candidates** = for every visible character, the portrait view that MATCHES the shot's camera angle (front shot → front portrait, profile → side portrait) **plus** the most recent already-generated frame that shares this scene/camera.
+2. **Priority**: a recent prior frame of the same camera > an older frame > portrait-only; same-camera > different-camera. Keep relative positions (if a character was on the left, keep them on the left). Don't pick two references that show the same face.
+3. **Explicit binding**: write a generation prompt that maps each reference to what it's for — "ref 1 (front portrait) → facial features & hair; ref 2 (previous frame) → lighting & background".
+4. Generate the shot with `generate_video` **image-to-video** using those reference images.
+
+## 4b. Verify the keyframe BEFORE you pay to animate
+
+For a character-critical shot, generate the **first-frame image** first (cheap), check it, and only then drive the video from that locked frame — catching drift at the still is far cheaper than discovering it after paying to animate.
+
+- **Check the keyframe against the bible** on the identity axes, in priority order: 1) character — gender, age, ethnicity, facial features, body shape, hairstyle; 2) spatial — relative positions/perspective match the reference (left stays left); 3) accuracy — matches the shot's description. Read it yourself if multimodal; if you cannot see images, mark it unverified and lean harder on a strong locked reference.
+- **No implicit re-rolls.** If multiple image candidates are desired, put each candidate in the EDL before Gate C so the displayed count is exact. After a failed/interrupted provider attempt, do not retry the same segment automatically; the durable transaction fails closed until the user explicitly authorizes another paid attempt.
+
+## 5. Carry-forward (continuity between shots)
+
+After a shot is generated, pull its representative frame with `stage-edit edit_video --op extract_frame` (e.g. its last frame) into `project/frames/`. That frame becomes a high-priority reference for the NEXT shot in the same scene — this is what carries lighting, composition, and the exact current look forward, so drift doesn't accumulate.
+
+**Cache the decision, not just the pixels.** Record each shot's chosen references + the binding prompt (e.g. in the plan/segment) alongside the produced frame. A resumed run then reuses the SAME references and prompt and reproduces the same frame, instead of re-rolling the selection and silently drifting from the earlier run.
+
+## 6. Long script / novel → movie (global planning first)
+
+For long-form, plan globally BEFORE generating:
+
+1. Chunk the source; for a very long novel, index it (`kb_*`) and retrieve the relevant chunks per event instead of holding it all at once.
+2. Extract **events → scenes**; extract characters per scene.
+3. **Merge characters** so the bible is global: same person across scenes → one entry (track the name variant each scene uses); same name but conflicting static features (e.g. a child vs. the adult years later) → split into two characters. New character → append.
+4. Carry the ONE global bible (locked portraits) through every scene, so a character looks identical across the whole story.
+
+## Default scope caps (cost control)
+
+A story multiplies billable calls (portraits per character + clips per shot + carry-forward frames). Default bounds unless the user explicitly asks for more: **≤ 3 characters**, **≤ 3 scenes**, **≤ 6 shots total**. Above these, state the full count + the rough number of billable image/video generations in the approval-gate proposal and get the user's explicit OK before generating anything.
+
+## Rules & boundary
+
+- **The anchor is sacred**: a character's front portrait is generated once and reused; never silently regenerate it (that's how looks drift).
+- **Cost discipline**: portraits + per-shot generation are billable; represent every provider call as one signed generate segment, state the exact count in the Gate C evidence supplied to `gate-control`, and pass the owning approved plan/segment metadata to every generate tool call.
+- This skill is the consistency METHOD; it does not itself author HTML (composition skill) or cut user footage (editing skill). It sits on top of the generation line.

+---
+
+# stage-decide
+
+The hard, valuable part of editing real footage is not executing a cut you already chose — it is
+**figuring out WHAT to cut**: understanding opaque raw material, removing its intrinsic defects
+(dead air, fillers, weak takes), and reducing it without losing the point. This skill is the
+"understand → decide" layer; `stage-edit` executes the cuts you land on.
+
+Host-neutral: describe what to produce; the host provides the operations. In Orkas, use skill scripts:
+`stage-edit edit_video --op trim_silence` / `--op remove_fillers` (deterministic auto-cuts that return evidence),
+`stage-edit analyze_media --op scenes` (cut candidates), `--op quality` (blur/exposure/black/freeze flags),
+`video_studio` `op: "speech.transcribe"` for transcription, and `stage-edit analyze_media --op silence`.
+
+## Use this when
+
+The user supplies real footage AND the work is to **select or clean**, not to run a known edit:
+"cut this 40-min recording to a 2-min highlight", "remove the ums and dead air", "make 3 clips from
+this podcast", "tighten this talking-head". If they already gave you timecodes ("trim 0:10–0:35"),
+skip this — that is plain `stage-edit`.
+
+## Method
+
+1. **Understand the material first** (never decide against footage you have not measured):
+   - `probe` for duration/resolution.
+   - Spoken footage → use `video_studio` `op: "speech.transcribe"` so you cut on sentence/word boundaries, never mid-word.
+   - Visual reduction → `scenes` for shot boundaries; bound the moments you keep on these candidates.
+   - Dead air → `silence` to see the gaps.
+2. **Decide — deterministic first, judgment second:**
+   - **Cleaning is mechanical** — use the auto-cuts: `trim_silence` (drop dead air), `remove_fillers`
+     (transcribe → drop um/uh). They are reliable and return the spans they removed.
+   - **Build a candidate pool first** — turn the signals into a structured list of selectable pieces:
+     each transcript sentence (spoken footage) or scene segment (visual footage), annotated with its
+     timecode, duration, and quality flags/score. Select FROM this list — do not eyeball raw footage.
+   - **Selection is judgment** — when picking highlights / reducing length, ground EACH kept span on a
+     measured signal (a scene boundary, a transcript sentence, a scored moment). Keep whole sentences;
+     pad cuts so they are not jarring; for a talking-head the jump-cut keeps audio and video in sync —
+     do not desync the lips.
+   - **Best take among repeats** — when the same line was recorded several times, do NOT guess: write a
+     `takes.json` (`[{id, text=the take's transcript, quality_score from "quality", duration_sec}]`) and
+     call `"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op rank_takes --takes project/takes.json`. It groups the repeats and tells you which to KEEP (best quality)
+     and which to drop. Choosing what to keep across DIFFERENT moments is still your judgment; this only
+     resolves "which of these identical takes".
+   - **Quality triage** — `quality` flags bad shots (blurry / too dark / over-exposed / black / frozen).
+     Drop or avoid flagged spans; blur is content-relative (compare, do not threshold blindly), dark /
+     black / freeze are absolute defects.
+   - **Visual / silent footage (no speech)** — the content is in the PICTURE, so transcript is empty.
+     Sample frames at candidate moments with `stage-edit edit_video --op extract_frame` and JUDGE THEM YOURSELF if
+     you can see images (you are the vision — no separate vision model). If you CANNOT see images, ground
+     on `scenes` + `quality` only and mark every visual judgment UNVERIFIED, or ask the user which moments
+     matter — NEVER invent what is on screen, and never escalate to a separate billable vision model.
+3. **Record the edit strategy and references.** Write `plan.json::edit_strategy` with deterministic/mixed mode, concrete objectives, only the transcript/OCR/scene/silence/quality/vision signals actually used, and non-overlapping preserve/may-change boundaries. Record every source or guiding image/video in top-level `references`; video timing or motion guidance needs temporal anchors.
+4. **Record evidence — make every cut auditable.** For each kept/cut segment in `plan.json`, set
+   `reason` (why this moment), `confidence`, and `evidence` (the auto-cut tools return removed/kept
+   spans; for your own selections, cite the signal). This is the whole point — not a black box.
+5. **Produce** the tightened clip (the auto-cut tools output it directly; for selection, trim the kept
+   spans and concat per `stage-edit`).
+
+## Honest ceiling — present a DRAFT, let the user decide
+
+- **High confidence (ship it):** silence/filler removal, transcript-driven sentence selection, quality
+  filtering. These are deterministic and proven.
+- **Low confidence (mark it, never claim it is "right"):** narrative arc, emotional beats, comedic
+  timing, "does this cut FEEL right". These are subjective with no ground truth. Offer the rough cut as
+  a first pass, flag the low-confidence calls, and invite the user to adjust at the draft gate.
+
+Never over-claim. An evidence-backed rough cut the user can audit and tweak beats a confident black box.

+description_en: Intelligent editing knowledge for real footage: understand it through transcript/OCR/scene/silence/quality/vision evidence, then choose deterministic timeline editing or constrained semantic AI editing; core of repurpose, montage, cleanup, and local content changes.
+---
+
+# stage-edit
+
+For the VideoStudio EDIT line, the edit decision list lives in `project/plan.json` and `gate-control` owns its Gate B authorization transition. Start/resume execution with `production.status`; do not run trims, assembly, or localization against a changed or unsigned EDL. Runtime `status`/`produced_path` updates do not invalidate the signed creative plan, but changing cuts, copy, source allocation, or delivery settings does.
+
+How to intelligently edit **real user-supplied footage** while keeping the source and every decision auditable. Deterministic operations still handle cuts, joins, captions, overlays, reframes, and audio. When the request changes pixels semantically—remove an object, alter a background, relight a shot, or make another content-aware local change—keep the EDIT route and execute only that bounded segment through signed video `operation:"edit"` after paid-generation approval.
+
+**Where the footage comes from.** A user-uploaded clip arrives as a chat attachment marked `model_readable="false"` with a `path` (see the attachment list). That flag means "not vision input", NOT "unusable" — the file is exactly what these media scripts operate on. Copy it into the project's `raw/` (or pass its attachment path directly as `--input`) before probing; never treat a `model_readable="false"` clip as something to skip.
+
+## Intelligent edit contract
+
+Write `project/plan.json::edit_strategy` whenever VideoStudio decides what to change rather than merely executing user-supplied timecodes:
+
+- `mode`: `deterministic` for transcript/OCR/scene/silence/quality/vision-driven timeline decisions, `semantic` for AI pixel changes, or `mixed` when both are necessary.
+All four fields below are non-empty arrays of strings — one entry per item,
+never a single sentence. `objectives` is the one most often written as prose;
+the validator rejects a bare string with `E_EDIT_STRATEGY_BOUNDARY`.
+
+- `objectives`: the exact editorial or pixel-level changes requested, one per entry.
+- `decision_signals`: the provenance list of evidence actually used (`timecode`, `transcript`, `ocr`, `scene`, `silence`, `quality`, `vision`, `semantic_model`). Include each supplied or analyzed signal that supports the decision, not only the signal used to execute it.
+- `preserve` and `may_change`: non-overlapping boundaries. `may_change` must name every class of change the user authorized — omitting one silently narrows the plan's declared authority below what they asked for.
+
+Declare every source/reference image or video in top-level `references` with `media_type`, reproduce/edit/guide intent, `intent_basis`, roles, required state, preserve/may-change, and target segment ids. This applies to deterministic trims/highlights as well as semantic edits: `spec.input_id` and `edit_strategy` do not replace the top-level source contract. User-declared requirements override defaults; only an unspecified reference defaults to guide/inferred. Video reproduce/edit/motion/timing contracts need one `{source_start_sec,source_end_sec,target_segment_id}` temporal anchor for every targeted segment. A semantic video edit is represented as `source:"generate"`, `media_kind:"video"`, `operation:"edit"`, with the original in `reference_video_paths`/`reference_video_urls`; it still belongs to the EDIT workflow and its count enters Gate C.
+
+## How to call the media scripts
+
+Use these `run-skill` entry points whenever this document says `stage-edit edit_video --op ...` or `stage-edit analyze_media --op ...`. Exception: transcription runs through the required built-in `video_studio` tool with `op: "speech.transcribe"`. Compatibility is handled by the marketplace `min_app_version` field before install.
+
+```bash
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-edit edit_video -- --op probe --input raw/clip.mp4
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-edit edit_video -- --op trim --input raw/clip.mp4 --start 12 --duration 8 --output project/cuts/seg-1.mp4
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-edit analyze_media -- --op ocr --input raw/screen-recording.mp4
+```
+
+The scripts return JSON. A non-zero exit means the operation failed; fix the input/plan before proceeding.
+
+**Subtitle safety hard rule.** Burn captions only through `stage-edit edit_video --op burnsubs`; do not hand-write `ffmpeg` subtitle, `drawtext`, or PNG-overlay fallback commands. In particular, never use `ffmpeg -loop 1` image inputs for subtitle overlays from bash. If `burnsubs` fails with `E_EDIT_BURNSUBS_UNSUPPORTED` or an ffmpeg filter-support error, stop and report the blocker instead of improvising a custom ffmpeg graph.
+
+**If the task is to FIND / SELECT / REDUCE / CLEAN rather than run a known timecode edit** — remove dead air, drop fillers, pick highlights, cut a long recording down — read `stage-decide` first: it covers understanding the footage and producing an evidence-bearing rough cut (the deterministic auto-cuts `trim_silence` / `remove_fillers` and scene-candidate detection). This skill is for executing cuts you have already chosen.
+
+**Two assembly paths — pick by whether the result needs to stay re-editable:**
+
+- **Plan-backed (anything the user may later adjust: narration, multi-shot, segmented edits).** Author `project/plan.json` (the segments EDL — see `stage-plan`) carrying ONLY the operations the user asked for (the deltas) — everything else is the source, passed through untouched. Keep each editable concern SEPARATE in the plan: each narration line in `tracks.narration.segments` with its own `produced_path`, each caption in `tracks.captions.lines` as data, each segment carrying `status`/`produced_path`. A track is active only when it has executable content (narration: voice + non-empty lines; music: path; captions: non-empty lines or `from`); omit or set disabled tracks to `null`, and skip legacy empty objects completely. Assemble with `stage-edit edit_video` (trim → concat → mix → burnsubs). Because plan.json holds every piece separately, a later "fix one caption / re-voice one line" is a one-entry edit + one re-render — do NOT pre-bake (e.g. one big narration file), which destroys that separability.
+- **One-shot deterministic (a plain trim or concat the user just wants done).** Use `stage-edit edit_video` directly; write no plan.json.
+
+For every plan-backed follow-up, start with `production.status` and compare the
+requested delta with the signed EDL. A caption typo/translation, one narration
+line, one cut, or one output in a multi-output batch invalidates only that
+entry and outputs derived from it. Reuse the source probe, transcript/OCR,
+unaffected cuts, audio, and sibling outputs; do not retranscribe or re-run a
+semantic/billable edit unless its signed input actually changed. A replacement
+source clip is different: re-probe and regenerate evidence for that source,
+invalidate its dependent cuts/tracks/drafts, and preserve unrelated inputs and
+history.
+
+File identity is content-addressed; a filesystem locator is not creative
+intent. When a missing EDIT source is found at a new path with the exact
+recorded byte SHA-256, keep its signed logical source identity and approved EDL
+unchanged. Record the new physical path under the plan's excluded
+`_runtime.asset_locators` envelope with the verified hash, and pass that
+resolved path to `stage-edit edit_video`; do not rewrite the signed
+`spec.input_id`, open the gate resolver, re-probe, retranscribe, or re-run OCR.
+`production.status` reports the approval facts but there is no

+
+## The deterministic editing loop
+
+1. **Ingest — always probe first.** For every input clip, read its metadata (duration, resolution, fps, codecs). Never plan a cut blind; a `trim` past the real duration produces an empty or broken clip. (Orkas: `stage-edit edit_video --op probe`.)
+2. **Plan — write an `edit_decisions` timeline.** From the user's intent + the probe results, decide the exact segments and order, and write them to `project/edit_plan.json` so the plan is inspectable and re-runnable. Shape:
+   ```json
+   {
+     "segments": [
+       { "input": "raw/clipA.mp4", "start": 12.0, "duration": 8.0 },
+       { "input": "raw/clipB.mp4", "start": 0.0,  "duration": 5.5 }
+     ],
+     "subtitles": "raw/captions.srt",
+     "overlay": { "media": "assets/logo.png", "x": 40, "y": 40 }
+   }
+   ```
+   Every `start`/`duration` must be inside the probed duration of its input.
+3. **Execute in order.**
+   - `trim` each segment to its own file (`project/cuts/seg-1.mp4`, ...).
+   - `concat` the cut files (in plan order) into one (`project/render/edited.mp4`).
+   - If subtitles: `burnsubs` the `.srt`/`.ass` onto the concatenated video. Do not bypass `burnsubs` with a manual ffmpeg subtitle/overlay command if the tool fails.
+   - If an overlay (logo / lower-third image / PiP): `overlay` it at the planned position.
+4. **Publish** the final file.
+
+## Conditional transcript, localization, and screen-grounded narration
+
+For topic-based highlight selection, automatic captions, localization/dubbing,
+or narration added to existing footage, read
+[transcript-and-screen-grounded-editing.md](references/transcript-and-screen-grounded-editing.md)
+before authoring the EDL or generating speech. Ordinary known-timecode trim,
+concat, overlay, and audio-only operations do not load this branch.
+
+## Director judgment (editing line)
+
+Craft calls per repurpose/montage line, on top of the shared craft reference (video-craft).
+
+**Cut craft (every editing job — this is the canonical set; the assembly line references it).** On top of `video-craft` (pacing §3, transitions §5, audio §7):
+
+- **Cut the moment, not the clip.** A 12 s clip usually holds one ~3 s moment that earns its slot — trim to that window. End the cut on a held look, not on the action moving off; leave a few frames of handle at each end so a dissolve doesn't clip the moment, and never freeze on a static last frame (reads as a glitch).
+- **A restrained transition vocabulary for cut-driven pieces:** ≤ 4 types across the whole piece — hard cut (default, most invisible), dissolve (emotional siblings / time passage), fade-to-black (act breaks), fade bookends. In a documentary/montage register, wipes / push-slide / zoom-blur / glitch read as social-media language — avoid (this is stricter than the explainer norm in `video-craft` §5, where a wipe can mark a step).
+- **Bridge the hardest cuts with sound** — carry the outgoing clip's ambient under the incoming for ~0.5–1.5 s (L-cut), or start the next audio early (J-cut); audio continuity hides a visual seam. Plus the one held silence from `video-craft` §7.
+- **Adjacent-diversity + a reason per cut.** Don't place the same subject at the same shot size, or the same palette, back-to-back — break the pattern at least every ~4 cuts. If you can't write a one-line reason for a cut, it's arbitrary — reconsider it.
+
+Per repurpose/montage line:
+
+- **Social clip / clip-factory** — per clip = hook (0–2 s) → sustain → clean outro; optimize the first 2 frames; start on motion/face/result; lock a batch style (caption / hook position / watermark) so a series feels cohesive; don't crowd frame 1 with hook + caption + watermark + lower-third at once.
+- **Podcast-repurpose** — audio is the hero; pick quotable moments; speaker video if it exists, else a simple audiogram / quote card; keep the visual system simple and repeatable; preserve attribution + CTA.
+- **Screen-demo** — zoom only for legibility/orientation, steady while the viewer reads; reset to wide context between phases; ≤ 2 attention cues at once; label sped-up sections; keep UI text sharp (higher bitrate), don't force an unreadable vertical crop.
+- **Localization** — treat each language as its own deliverable; dubbed audio won't match source timing, so plan holds to flex; re-render or cover any baked-in text per language; subtitle line lengths differ by language; lip-sync only where a close-up mouth mismatch would distract.
+- **Documentary-montage** — concrete sensory shot descriptions, not abstract themes; one grade/LUT across all clips is what unifies mixed sources; budget 2–3 hero slots longer holds; a music bed + an end-tag.
+- Before publishing, normalize the mix against the targets in video-craft §7 (~−14 LUFS integrated, true-peak ≤ ~−1 dBTP). (Orkas: `stage-edit edit_video --op normalize_loudness`; use `--op loudness` only for diagnosis without writing an output.)
+
+## Rules
+
+- **Timecodes come from the user, from probe, from a transcript, or from on-screen text (OCR) — never guessed.** If the target moment can't be located deterministically (no timecode, no transcript/OCR match), ask the user for the timestamp.
+- **Layer composition over footage when the brief needs designed elements** (animated lower-thirds, kinetic captions, hooks): produce those with the composition skill as an overlay/element and `overlay` them, rather than trying to draw them in ffmpeg.
+- **One output file** at the end; intermediate cuts live under `project/cuts/` and are not the deliverable.
+
+## Boundary / non-goals
+
+This skill owns the EDIT workflow. It executes deterministic EDL operations directly and delegates only bounded semantic pixel changes to the signed video-edit provider path. It does not author HTML compositions. For transcript/scene/silence/quality-driven selection, use stage-decide first and persist its evidence in `edit_strategy` and per-segment reasons.

+# Transcript and screen-grounded editing
+
+Use this reference only for topic-based highlight selection, automatic
+captions, localization/dubbing, or narration added to existing footage.
+
+## Transcription-driven selection and localization
+
+When the user wants highlights or clips "about X", automatic captions, or a
+localized version, transcribe first with `video_studio`
+`op: "speech.transcribe"` and `timestamps: "word"`:
+
+- **Highlight / clip selection:** read the transcript, choose the time ranges
+  whose words match the requested topic or moment, and feed those
+  `start`/`duration` values into the `edit_decisions` segments. The timecodes
+  must be evidence-based, not guessed.
+- **Auto-captions:** turn the transcript into an `.srt`, then use `burnsubs`.
+- **Localization / dubbing:** transcribe, translate, synthesize the translated
+  narration, then use `stage-edit edit_video --op mix` with
+  `--on-existing-audio replace`. The dub replaces the original voice; do not
+  stack it on top. Burn translated captions separately.
+
+## Ground narration on on-screen text
+
+Adding narration to any existing video is plan-first and ordered. Author
+`project/plan.json` before generating speech and let it drive generation. Do
+not synthesize one narration blob and describe it afterward.
+
+1. **Analyze the video first.** Probe duration, run
+   `stage-edit analyze_media --op ocr` for on-screen text, and run
+   `video_studio` `op: "speech.transcribe"` for spoken audio. For title cards,
+   slideshows, and screen recordings, OCR is mandatory rather than a fallback.
+   Do not describe the product from memory.
+2. **Author `project/plan.json` as the segments EDL.** Use the exact
+   `stage-plan` skeleton. `source` is the method enum `edit`, not a file path;
+   the clip belongs in `spec.input_id`, duration uses `target_sec`, and
+   `tracks` is an object. Carry only the requested delta—keep the picture and
+   add narration:
+   - Add one primary `edit` segment spanning the source timeline with
+     `source:"edit"`, `layer:"primary"`, the clip length as `target_sec`, and
+     `spec.input_id`/`in_sec`/`out_sec` covering the clip. Do not add crop,
+     scale, or reframe unless requested.
+   - Add `tracks.narration`. Copy
+     `synthesis:{route_ref,voice_ref,display_name,language,speed}` from
+     `video_studio speech.capabilities` for the deliverable's exact BCP-47
+     language. Create one `{ text, start_sec, target_sec }` line per on-screen
+     beat, derived from the OCR/transcript table before TTS. Never invent a
+     voice id or use one paragraph for the whole clip.
+   - Use `delivery_promise:{ type:"source_led", source_required:true }` and set
+     `aspect` from the source's probed dimensions.
+   Keep each narration line separate so a follow-up can re-voice one line.
+3. **Generate from the plan.** Run `generate_speech` once per narration line
+   with `target_duration` equal to its `target_sec`, save it under
+   `project/assets/narration/line-XX.mp3` or another `project/...` path, and
+   record `produced_path`. Estimate copy length before generation. If one line
+   does not fit naturally, shorten it and retry once; use deterministic
+   assembly for small residual timing differences. Coverage should span the
+   clip rather than stop midway.
+4. **Assemble without changing the picture.** Pass the source video through
+   with `-c:v copy`. Place every narration line at its `start_sec` in one
+   `stage-edit edit_video --op mix` call via `--audio-segments`, then run
+   `--op normalize_loudness`. Use `--on-existing-audio mix` to retain source
+   sound or `replace` to drop it. Burn `tracks.captions.lines` separately when
+   present. Record line status/paths and the top-level draft/video paths in the
+   plan. Never pre-bake one large narration file.
+5. **Self-check before presenting.** Validate the plan with
+   `"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op validate --plan project/plan.json`.
+   Every narration line must have a produced path and an OCR/transcript-aligned
+   window, coverage must approximate the whole clip, and
+   `project/render/video.mp4` must exist.
+
+If the clip has no spoken audio, or meaning lives in on-screen text, an empty
+transcript does not mean an empty screen. Resolve evidence in this order:
+
+1. Run OCR across the clip and use its `{startSec, endSec, text}` segments to
+   align each narration line to its own window.
+2. Only if the OCR runtime is unavailable, extract frames across the whole
+   clip and read them with the current model's own vision capability.
+3. If neither OCR nor image reading is available, stop and ask the user for a
+   short outline of the on-screen beats. Do not write narration from topic
+   knowledge or escalate to a separate paid vision model.
+
+Before the draft, confirm every narration segment matches the OCR or transcript
+evidence in its time window.

+description_zh: AI 生成视频线的知识——口播/数字人、电影感/AI b-roll：用形象图 + 图生视频保镜头内一致、按分镜逐镜生成再组装成片；「生成为主」产线的核心。
+description_en: Knowledge for the AI-generated-footage line — talking-head / avatar and cinematic / AI b-roll: a character still + image-to-video for in-shot consistency, generate per shot, then assemble; core of the generation-primary line.
+---
+
+# stage-generate
+
+How to produce AI-generated footage and how to execute a **bounded semantic video edit** already planned by the EDIT/AUTO workflow. Designed HTML remains composition work; deterministic cutting remains stage-edit work. In Orkas use `generate_image`, `generate_video`, and `generate_speech`, then assemble through `stage-edit`. Every billable call belongs to a signed `project/plan.json` generate segment and carries `production_plan_path` plus `production_segment_id`.
+
+## Pattern A — talking-head / spokesperson (口播 / 数字人)
+
+1. **Character still:** generate one image of the presenter / avatar with the intended look. **Keep this reference image** and reuse it for every shot of the same character.
+2. **Bring it to life:** generate a video *from* that image (image-to-video). When the provider returns speech + **built-in audio**, that audio is the deliverable voice — it is **lip-synced to the mouth in the clip** — so keep it and do NOT synthesize a separate narration. Only when the clip comes back **silent** do you synthesize the narration (`generate_speech`) and add it as the audio track. Synthesizing a fresh TTS track over a clip that already speaks is the #1 talking-head defect: the new audio has different wording/timing/length, so the voice no longer matches the lips.
+3. **Polish:** add captions / a lower-third / a hook by authoring a small composition (composition skill) and overlaying it onto the clip — **visual-only**. Preserve the clip's own (lip-synced) audio through assembly; a captions composition must not carry a narration `<audio>` track that would replace the clip's voice.
+
+## Pattern B — cinematic / AI b-roll montage
+
+1. **Storyboard** the shots (each: prompt, camera motion, duration).
+2. **Generate each shot** (one generate-video call per shot; reuse a shared reference image / consistent style prompt for visual continuity).
+3. **Assemble:** concatenate the shots in order, add transitions, and overlay a title / captions from a composition.
+
+## Consistency (basic — deep consistency is a later capability)
+
+- **Within a shot:** drive the clip from a reference image (image-to-video) to lock the subject.
+- **Across shots:** reuse the **same** reference image / style prompt.
+- Full multi-shot character consistency, Cameo (upload-a-photo-as-the-lead), and long-narrative planning are a separate, more advanced capability — out of scope here.
+
+## Director judgment (generation line)
+
+Craft calls specific to AI-generated footage, on top of the shared craft reference (video-craft):
+
+**Talking-head / spokesperson**
+- Understand what's said before placing overlays; time graphics to the spoken words.
+- **3–6 overlays/min**, varied types; keep them in speaker-safe zones — never over the face.
+- Cut silences and filler; for vertical, keep subtitles low so they don't cover the face.
+
+**Cinematic / AI b-roll**
+- Open on a hero frame; keep a small transition palette (cut / fade-to-black / slow dissolve / restrained push-in).
+- Protect earned moments — don't over-cut a held look or a deliberate silence.
+- Design each shot first-frame → last-frame and let audio dynamics carry momentum (shot language: video-craft §10; identity across shots: stage-consistency).
+- **Frames are static snapshots, never an action in progress** (`video-craft` §10); in motion / last-frame text, name characters by visible features, not names (the model conditions on pixels, not labels).
+- **Spend keyframes by how much the shot changes (cost gate).** If a shot's start and end look nearly the same — a talking head, a small pose/expression change, a gentle pan — it needs only ONE keyframe and motion fills the rest (variation_type `small`). Only a shot that ends somewhere visually different — a new subject enters, a wide→close transition, a big camera move — needs TWO keyframes for the model to interpolate (`medium` / `large`). Don't pay to generate an end-frame you don't need.
+
+## Default scope caps (cost control — do not exceed without explicit user request)
+
+Generated clips and images are **billable hosted calls**, so bound the run by default:
+
+- **Shots / clips: ≤ 6** per video.
+- **Characters: ≤ 3** per video.
+- **One aspect ratio** per run.
+
+If the brief seems to need more (a long story, many scenes, many characters), DO NOT silently fan out — state the larger count + the rough number of billable generations in the approval-gate proposal and let the user opt in first. Treat anything above these caps as requiring explicit confirmation.
+
+## Rules
+
+- **Cost/time discipline:** every generated clip is a hosted, billable, multi-second call. State the exact shot/character count in the approval-gate proposal; never start generating before the user has approved the count.
+- **Native Gate C evidence:** call `production.status` and pass the current plan signature, exact generate-segment count, configured external provider, external-billing disclosure, and transaction state to `gate-control`; the open build cannot verify the provider's billing or balance locally. A provider call without the current plan/segment signature is rejected; a completed transaction is reused. A `pending` or failed transaction is not safe to retry under its prior authorization, so report the exact state and let `gate-control` decide whether a fresh paid-attempt review is available. If the latest status evidence is already present and the user explicitly wants another attempt, do not call `production.status` again: open the fresh paid-generation review returned by `gate-control`, make no host call in that turn, and wait for its later approval before dispatching a new output path. Never invent a transaction-recovery provider call.
+- **Dispatch boundary:** distinguish a provider attempt from a local failure before dispatch. Literal native evidence `request_disposition:"not_sent"` plus `charge_status:"not_charged"` means no provider attempt exists. If the signed segment intent, authorization, and output path are unchanged, repair the concrete local input/serialization defect and call the original `generate_video`/`generate_image` segment once under the persisted authorization; do not open a fresh Gate C. Only `sent`, `unknown`, `charged`, or an unreconciled provider transaction enters the fresh-paid-attempt path above. Preserve every completed sibling transaction in either case.
+- **Do not predict provider success:** a control/planning response that has not received the retried provider result stops at that exact provider call and opens no Final confirmation. In an actual tool-enabled turn, a successful returned shot may continue immediately through complete montage assembly and parent QA; only the resulting current review artifact's real path, signature, and passing QA may open Final video confirmation. A failed/unknown result preserves siblings and transaction evidence instead. Never list a Final gate from a hypothetical future montage or omit parent QA between assembly and that gate.
+- **Partial batches and shot revisions:** treat each signed generate segment as an independent durable transaction. If two shots completed and one is pending, failed, or revised, preserve and show the two completed shots; never redispatch them or roll their cost into a new approval. A user change to one shot invalidates only that shot's plan/quote/paid authorization plus downstream assembly evidence. After the bounded plan amendment, request a fresh quote and paid-generation confirmation for the changed segment only, use a new output path, then rebuild the complete current montage. The new review artifact must contain the preserved shots and the new shot; an approval of an older montage cannot authorize it.
+- **Exact settings:** each video segment's EDL spec fixes `media_kind`, prompt, `operation:"generate"|"edit"`, every reference path/URL, top-level plan aspect, `generation_duration_sec`, resolution, quality, and `generate_audio`. Never substitute `text_to_video`, `duration_sec`, or `audio`; those aliases are rejected. Each image/portrait/keyframe is also a distinct `media_kind:"image"` segment whose size and references are signed and has no operation. Do not add, remove, reorder, or change those values between Gate C and the provider call.
+- **Semantic edit boundary:** `operation:"edit"` requires a top-level video reference with `intent:"edit"`, target-segment and temporal anchors, plus `edit_strategy.mode:"semantic"|"mixed"`. The prompt may change only `may_change`; identity, content, motion, timing, and audio in `preserve` remain explicit. Never turn an edit into an unconstrained regenerate call.
+- When `gate-control` returns a fresh paid-attempt review, stop after presenting it. A later authorized retry must use a new output path.
+- **Audio (talking-head):** a generated talking-head clip's built-in audio is **lip-synced** to its mouth. Treat it as the final voice: keep it through assembly and finalize. NEVER add or mux a separately-synthesized narration over a clip that already speaks — it desyncs from the lips. Synthesize narration ONLY for a silent clip, or for b-roll / off-screen voiceover where no mouth is visible.
+- **Brief drives params:** pass the requested aspect ratio and per-shot duration to each generation call.
+
+## Boundary / non-goals
+
+Generation-primary work uses this skill directly. EDIT/AUTO may invoke it only as the executor for an already approved semantic edit segment; route ownership, source analysis, preservation boundaries, and final assembly remain with the edit plan. Designed HTML goes to composition; deterministic cuts/joins go to stage-edit.

+
+# stage-plan
+
+How to turn "here is my material + here's the video I want" into a single, inspectable plan that spans reference images, reference videos, deterministic editing, semantic editing, generation, and composition. The output is `project/plan.json` — a cross-modal Edit Decision List (EDL) — which the assembler walks. Host-neutral: ingest evidence comes from `stage-edit` skill scripts (probe / silence / ocr / scenes / quality / extract_frame) plus `video_studio` transcription; this skill provides the plan validator, and line producers execute the signed decisions.
+
+**Where the material comes from.** User-uploaded clips arrive as chat attachments marked `model_readable="false"` with a `path` (see the attachment list). That flag means "not vision input", NOT "unusable" — it is source material to ingest with the scripts below. Copy each into `raw/` (or pass its attachment path as `--input`) before probing; never skip a `model_readable="false"` clip or plan around material you have not actually ingested.
+
+## How to call ingest scripts
+
+Use `stage-edit` scripts for factual ingest before writing the plan, except transcription, which runs through the required built-in `video_studio` tool.
+
+```bash
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-edit edit_video -- --op probe --input raw/clip.mp4
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-edit analyze_media -- --op ocr --input raw/screen-recording.mp4
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-edit edit_video -- --op extract_frame --input raw/clip.mp4 --start 3 --output project/frames/clip-3s.png
+```
+
+Call transcription directly as:
+
+```json
+{"op":"speech.transcribe","input_path":"raw/clip.mp4","transcript_path":"project/transcripts/clip.json","timestamps":"word"}
+```
+
+These script/tool calls return JSON. Their output is the evidence for `project/ingest.json`.
+
+## How to call the plan validator
+
+Use the skill script, not a deprecated direct `video_plan` tool:
+
+```bash
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op validate --plan project/plan.json
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op promise_check --plan project/plan.json
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op summarize --plan project/plan.json
+```
+
+For repeated takes:
+
+```bash
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" stage-plan video_plan -- --op rank_takes --takes project/takes.json
+```
+
+The script returns JSON with a `text` field for the user-facing summary. `validate` exits non-zero when the plan is invalid; `promise_check` exits non-zero when the delivery promise fails.
+
+Use this line when the deliverable is NOT cleanly one axis — e.g. "trim my clip, add a title card and captions, and a voiceover", or "my footage for the middle, generate an opener, compose the stats". For a pure single-axis job, route to that single line instead (see `video-router`).
+
+## Step 1 — Ingest from evidence, never from assumption
+
+You cannot plan against material you have not looked at. For EVERY supplied clip, before writing any segment:
+
+1. **Probe** it (`stage-edit edit_video --op probe`) for real duration / resolution / fps / audio presence. A plan that cuts past the real duration breaks.
+2. **Read its content** the cheapest way that fits:
+   - spoken audio → call `video_studio` `op: "speech.transcribe"` with `timestamps: "word"` → you now have timecoded words to cut on.
+   - silent / screen-recording / slideshow → `stage-edit analyze_media --op ocr` → per-timecode on-screen text. The audio being empty does NOT mean the screen is.
+   - need to judge what a moment LOOKS like (is the hero shot usable? is the product right-side up?) → read frames: `stage-edit edit_video --op extract_frame` then look at them. If you are multimodal you read them directly; if you cannot see images, say so and plan on probe/transcript/OCR evidence alone — mark those judgments unverified, do not invent them.
+3. Record what each input is good for in `project/ingest.json`: `{input_id, duration, has_audio, content_summary, quality_risks:[...], usable_for:[...], planning_implications:[...]}`. This is the factual basis the plan cites — segments reference `input_id`s from here. Rules:
+   - **`content_summary` is specific and from observation:** "45 s of interview, no b-roll, mono audio" — never "user provided footage". An entry is only "reviewed" if a real probe/transcript/OCR actually ran; never claim you looked at a clip you did not.
+   - **Usability heuristics:** video > 10 s → hero footage; > 3 s → b-roll; has speech → dialogue source; audio-only → narration/music source, production must supply the visuals; image-only → motion must come from animation or generation.
+   - **Quality risks to flag:** width < 720 / height < 480 (will look soft), clip < 3 s (limited use), mono audio, a still where the brief wants motion. A flagged risk the plan ignores is a planning bug — surface and resolve it at the Production plan confirmation.
+
+For every supplied image or video that constrains the result, also lock its requested relationship as `reproduce`, `edit`, or `guide`. Do not infer this from file origin. Copy or retain the exact media source and record its roles, protected attributes, allowed changes, and target segments. Video reproduction/editing or motion/timing guidance requires source-time-to-target-segment anchors.
+
+## Step 2 — Choose the delivery promise
+
+Pick ONE `delivery_promise.type` and make the whole plan keep it:
+
+- **source_led** — the user's footage is the hero (repurpose / highlight / localize / semantic edit). `source_required: true`.
+- **motion_led** — real motion (footage or generated video) dominates; composed cards are accents.
+- **compose_led** — designed HTML is the spine (explainer / data); footage/generation are accents.
+- **hybrid** — a deliberate mix (e.g. source hero + composed framing + generated opener).
+
+Set `motion_min_ratio` to the minimum share of runtime that must be real footage/generated video rather than composed cards — this is the AUTO/EDIT/GENERATE anti-slideshow guard. It does **not** measure GSAP/SVG/CSS animation inside a COMPOSE segment. For `type:"compose_led"`, set it to exactly `0`; native `composition.inspect`/`snapshot`/`draft` enforce HTML motion and scene quality instead. If a non-COMPOSE promise cannot hit its real-motion floor from the available material, say so at the Production plan confirmation instead of quietly shipping a slideshow. If `source_required` is true, at least one PRIMARY segment must be real footage: `source:"edit"`; `source:"provided"` with `spec.kind:"video"`; or a semantic video edit encoded as `source:"generate"` + `spec.operation:"edit"`, bound to a matching required top-level video reference with `intent:"edit"` that targets the segment. Ordinary generated video, a provided still, or an asset with missing kind never satisfies this promise.
+
+## Step 3 — Decompose into a cross-modal EDL
+
+Write `project/plan.json`. Every segment declares HOW it is produced (`source`) and WHERE it sits (`layer`):
+
+- `source`: **edit** (trim a real clip — needs `input_id` + `in_sec`/`out_sec`), **generate** (billable AI media — needs `prompt`, explicit `media_kind:image|video`, and the exact provider fields the call will use, written flat on `spec` — `operation`, `generation_duration_sec`, `resolution`, `quality`, `generate_audio`, plus every reference path/URL. A nested `spec.settings` object is not read by anything: the validator sees no provider fields and the host executes its own defaults. For video the approved defaults are plan aspect, clamped 4-15s target duration, 720p, balanced, audio on), **compose** (designed HTML — needs `kind` plus a complete `composition_plan.scenes` binding with each scene's id, approved_copy, narration_text, and semantic roles), **provided** (use a supplied asset as-is — needs `asset_id` and mandatory `kind:image|video`; unknown kind counts as neither footage nor motion).
+- `layer`: **primary** (the main timeline), **overlay** (sits over a primary via `over: <segment id>` — captions, lower-thirds, logo boxes), **bg** (behind). An overlay composited onto real footage must be SMALLER than the frame: the pipeline renders composed overlays as opaque video without an alpha channel, so a full-frame overlay does not blend — it replaces every pixel and deletes the footage under it (the assembler refuses this as `E_EDIT_OVERLAY_OPAQUE`). For a full-frame branded look on top of a real clip, plan edge elements (corner logo, lower-third strip) as the overlay, or make that beat a composed `primary` segment with no footage underneath.
+- `role`: MUST be exactly one of hook / body / proof / cta / transition — the schema rejects any other value (E_SEG_ROLE) and the plan fails validation. Narrative BEAT names from the arc ("payoff", "establishing", "climax", …) are NOT roles: map a payoff / closing / CTA beat to `cta`, an establishing / evidence beat to `proof`. Front-load the hook.
+
+Top-level `references` uses one format for both images and videos: `{id,media_type:"image|video",source,intent?:"reproduce|edit|guide",intent_basis?:"user|inferred",roles,required,preserve,may_change,target_segment_ids,temporal_anchors?}`. This declaration is mandatory for every user/source media item used by an edit, provided segment, or generation reference: a segment's `spec.input_id`, `edit_strategy`, or prose note does not replace it. When the plan uses no reference media at all, omit the top-level `references` field; never emit `"references":[]`, because an empty array is invalid when the field is present. Every reference `roles` entry MUST be exactly one of `content|identity|composition|structure|style|motion|timing|audio`; descriptive aliases such as `primary_source`, `speaker_identity`, `sync_reference`, or `semantic_edit_reference` are rejected by the EDL schema. Explicit user requirements always win and use `intent_basis:"user"`; only an unspecified reference may omit intent and safely default to guide/inferred. Image composition/structure may use spatial regions in downstream COMPOSE. A video reproduce/edit/motion/timing reference needs one valid `{source_start_sec,source_end_sec,target_segment_id}` temporal anchor for every id in `target_segment_ids`; one aggregate source/target time range with no `target_segment_id` is invalid.
+
+References remain live plan facts after initial ingestion. When the user adds,
+replaces, removes, relocates, or changes the declared role of a reference,
+compare the new declaration with the current signed plan before editing:
+
+- a source, identity, content, timing, audio, or signed fidelity-contract
+  change is a bounded plan amendment;
+- an implementation-only relocation with equivalent bytes refreshes the
+  locator and does not reopen approval;
+- a non-signed visual styling change may stay `visual_only` when it changes no
+  approved copy, semantic role, source mapping, identity, timing, or delivery
+  field;
+- a missing or unreadable reference blocks only segments that declare it
+  required. Preserve completed unaffected segments, show the current review
+  artifact, name the exact missing reference, and never fabricate its content.
+
+Keep the prior reference declaration and produced outputs as immutable
+history. Revalidate the complete EDL, invalidate only dependent segment
+outputs plus downstream assembly/review approval, and stop at the one next
+review artifact. If multiple references conflict, the current explicit user
+instruction outranks inferred defaults; do not blend mutually exclusive
+requirements silently.
+
+When VideoStudio chooses or transforms content intelligently, add `edit_strategy:{mode,objectives,decision_signals,preserve,may_change}`, where `mode` is a string and the other four are non-empty string arrays (a bare sentence in `objectives` is rejected as `E_EDIT_STRATEGY_BOUNDARY`). Use `deterministic` for evidence-driven cuts/cleanup, `semantic` for AI pixel edits, and `mixed` for both. `decision_signals` is a closed set naming the evidence actually used — `timecode`, `transcript`, `ocr`, `scene`, `silence`, `quality`, `vision`, `semantic_model` — never free-text findings; put the observed values in `objectives` or the segment specs instead. A semantic video edit remains an EDIT/AUTO workflow but is encoded as a billable `source:"generate"` segment with `media_kind:"video"`, `operation:"edit"`, and its declared original in `reference_video_paths` or `reference_video_urls`. Keep `edit_strategy` at the PLAN TOP LEVEL as a sibling of `segments`, never inside a segment. Its temporal anchor signs the exact source interval consumed by the target segment: a bounded 3s-7s child signs 3-7, while a full-duration 12s edit signs 0-12; in both shapes, `may_change` separately limits the actual pixel change to the requested 3s-7s target. The validator blocks semantic edits without a matching top-level edit reference, temporal anchor, edit strategy, and Gate-C count.
+
+Tracks are separate from the visual timeline. The top-level `tracks` container is always required and must be an object, even when the video has no active tracks: use `"tracks": {}` (or object members set to `null`), never `"tracks": null`. Source audio retained inside an edit segment needs no separate track. For a semantic edit that retains source audio, `generate_audio:true` requests an audio-bearing edit output but does not override the signed audio-preservation boundary. Before authoring an active narration track, call `video_studio` `speech.capabilities` with `language` set to the deliverable's BCP-47 narration language — the listing then carries only the voices cleared for it — and copy one returned selection into `tracks.narration.synthesis:{route_ref,voice_ref,display_name,language,speed}`. Never invent a provider voice id. Add at least one timed line `{text, start_sec, target_sec}` — `target_sec` is the line's DURATION, never its end time, and windows must not overlap (the validator rejects `E_NARRATION_WINDOWS_OVERLAP`; overlapping windows mix as two voices speaking at once). Each line gets a `produced_path` once synthesized, so one line can be re-voiced alone. `tracks.music` holds a real `path` + ducking, and `tracks.captions` holds `{ from?, style?, lines:[{text, start_sec, target_sec}] }` as DATA, not burned pixels. A disabled track must be omitted or set to `null`; never emit empty placeholders. Legacy raw `voice` plans are recovery-only and receive a validator warning. Put the billable-generation count in `cost_estimate` — gate C reads it.
+
+Fit narration in the plan before any TTS call: use natural cadence (about 2.2-2.7 English words/sec or 4-5 Chinese chars/sec), shorten over-budget lines here, and do not rely on repeated synthesis to discover timing.

+
+Field gotchas the validator enforces (these are the common breakers):
+- `source` is the **production-method enum** `edit | generate | compose | provided` — NOT a file path. The actual clip/asset goes in `spec.input_id` (edit) or `spec.asset_id` (provided).
+- Every segment needs `order` + `layer` + `spec`; use `target_sec` (not `target_duration_sec`/`duration`). At least one segment must be `layer:"primary"`.
+- Every compose segment's `composition_plan.scenes` is user-approved child content, not runtime metadata. The child manifest must reproduce those scene ids/copy/narration/roles exactly or native Gate B inheritance fails.
+- Every billable image, video, portrait, or generated keyframe is its own `source:"generate"` segment. Do not hide auxiliary generation outside the EDL or reuse one segment id for multiple provider calls.
+- Every edit/provided source and every generation reference has a matching top-level `references[]` declaration. `spec.input_id` proves where bytes come from, but it does not prove user intent, preserve/may-change boundaries, or target ownership.
+- For video reproduce/edit/motion/timing references, every `target_segment_ids` entry has its own temporal anchor with that exact `target_segment_id` and a valid source range. Never emit one aggregate anchor without a target id.
+- For a generated video, the signed provider fields are exactly `operation:"generate"|"edit"`, `generation_duration_sec`, `resolution`, `quality`, `generate_audio`, plus the documented reference arrays. Never write provider-family aliases such as `operation:"text_to_video"`, `duration_sec`, or `audio`; they are rejected because the host would otherwise execute different defaults. The aspect ratio comes from top-level `aspect` (a duplicate `spec.aspect` may not conflict). An image segment has no `operation`.
+- `operation:"edit"` requires at least one reference video and `edit_strategy.mode:"semantic"|"mixed"`; it is not an unconstrained variation. Every referenced source must match a top-level video reference with `intent:"edit"` targeting that segment.
+- `tracks` is a required **object** `{narration, music, captions}` — NOT an array and never top-level `null`. With no active tracks, write `"tracks": {}`. Otherwise include only active tracks; omit or use `null` for disabled members.
+- `delivery_promise` must MATCH this deliverable (Step 2) — do NOT copy the example's `hybrid`/`source_required:true`/`0.6`. A designed-HTML explainer is `type:"compose_led"`, `source_required:false`, `motion_min_ratio:0`; set `source_required:true` ONLY when the user's real footage must star. For other promise types, `motion_min_ratio` is the real-footage/generated-video floor you are actually committing to.
+
+Plan to the craft bar (`video-craft`): a hook in the first seconds, one idea per beat, readable type in safe zones, ducked audio, the right aspect.
+
+## Step 4 — Validate, then gate B
+
+1. Run `stage-plan video_plan --op validate` on `project/plan.json`. Fix EVERY error before going further — errors mean the plan cannot be executed or it breaks its own promise (e.g. `source_required` but no source segment). Reconsider warnings.
+2. Run `stage-plan video_plan --op promise_check` on the PLAN, before producing anything. It computes the planned motion ratio vs. the promise — a fail means the plan is already a slideshow / breaks its promise. Fixing the plan now is free; re-assembling later is not. Rebalance durations or convert a static beat to footage until it passes (gate D re-checks against the real cut).
+3. Gate B for a production EDL is two turns, not a state to re-check. In the presenting turn: call the native production status operation — for an unapproved plan it returns `plan_summary`, the host's own rendering — present that summary verbatim in the user's language, invite changes in one line, and end the turn. In the NEXT turn, the user's reply is the decision: hand it to `gate-control` and perform the Gate B transition it returns. Never present the summary twice for the same plan; an unapproved plan after the user already answered means you owe the transition, not another confirmation. Never ask for approval of a plan you have not shown — a locked-facts line plus the per-segment timeline with its copy is the minimum. Gate B is the highest-leverage checkpoint: it is far cheaper to fix the plan here than after assembly.
+4. Hand the displayed EDL, locked line, and production artifact state to `gate-control`, then perform only its returned Gate B transition. This project-scoped signature is the approval source for EDIT/AUTO/GENERATE and every AUTO child composition; never infer approval from a turn boundary.
+5. When the signed plan contains generate segments, call `production.status` and supply `gate-control` with the exact `cost_estimate.billable_generations` count, configured external provider, external-billing disclosure, and current transaction state. State that the open build cannot verify the provider's billing or balance locally, and do not present an unavailable provider as review-ready. Every billable tool call must carry the approved plan path plus its own segment id. A plan edit invalidates both Gate B and Gate C authorization.
+
+## Director judgment (end-to-end planning)
+
+The craft of weaving ONE good video across sources, on top of the shared craft (`video-craft`). This is where a multi-source plan becomes a video instead of a tour of clips:
+
+- **Decide the spine before the sources.** Write the beat arc (hook → gap → core → proof → payoff/CTA, `video-craft` §2 — these are BEAT names, not segment `role` values; a payoff/CTA beat's `role` is `cta`) source-agnostic FIRST, then assign each beat its cheapest sufficient source. Letting the material on hand dictate the structure is how end-to-end videos turn into a disjointed reel.
+- **Assign each beat to the source that earns it.** Real footage (edit / provided) carries proof / authenticity / the actual product or result — make it the hero of a `source_led` piece, not a cameo. `generate` is a last resort for a beat you can neither film nor compose (an impossible / expensive establishing shot, missing b-roll) — it is billable and reads synthetic if overused. `compose` is the connective tissue — titles, stats, definitions, transitions, the CTA card — cheapest and crispest for anything textual.
+- **Treat the promise as an editorial commitment, not a ratio to satisfy.** `source_led` means the user's material genuinely stars (the hero beats + real screen time), not 6 s buried under composed cards. For non-COMPOSE promises, set `motion_min_ratio` to the real-footage/generated-video feel you are promising; keep it `0` for `compose_led`.
+- **Pace the plan in `target_sec`** to `video-craft` §3: front-load the first payoff, one idea per beat, don't plan three equal-length beats in a row.
+- **Cost-aware craft.** Reach ~90% of the result with zero billable generation — reuse the user's footage, compose instead of generate, pull b-roll from existing frames. Generation is the exception you justify, not the default.
+- **Plan the moment, not the whole clip.** Set each edit segment's `in_sec`/`out_sec` to the one ~3 s window that earns its slot (the cut craft itself is in `stage-edit`). Every beat must earn a purpose (establish / proof / reaction); a beat you can't justify shouldn't be in the plan.
+- **Write each visual beat as a concrete photograph, not an emotion** — subject, action, environment, lighting (the rule + examples are in `video-craft` §11). If you can't picture a specific frame from the spec, neither can the generator.
+
+## Rules
+
+- The plan is the single source of production intent and its segments may carry the legacy execution facts `status` + `produced_path` as they complete; do not re-produce a segment already marked done. Native Gate B signs the normalized intent projection rather than the whole JSON container: stable content, references, language, timing, provider settings, and voice refs remain signed, while those execution facts and catalog display labels do not. Put new diagnostics in durable production state instead of inventing plan fields, because unknown plan fields intentionally remain approval-bearing.
+- Reference real `input_id`s from `ingest.json`; never cite a clip you have not probed.
+- Reference media by requested reproduce/edit/guide intent, never by which product created it. Preserve and may-change boundaries must not overlap.
+- `cost_estimate.billable_generations` must exactly equal the number of `source:"generate"` segments, including consistency portraits/keyframes; validation blocks a mismatch because Gate C depends on the count.
+
+## Boundary / non-goals
+
+This skill ingests and PLANS. It does not produce or assemble — that is `stage-assemble`, which walks the validated plan and delegates each segment to the compose / generate / edit lines.

+description_zh: 做出「优秀视频」的创作 know-how——钩子/叙事节奏/视觉层级/字体安全区/动效缓动/字幕/音频配比/平台规范/镜头语言/生成 prompt 写作 + 出片前自检。每条产线动手前都先过这套标准,把「能渲染」拉到「真的好」。
+description_en: The craft know-how that makes a video GOOD (not just rendered) — hooks, story pacing, visual hierarchy, type & safe zones, motion/easing, captions, audio mix, platform conventions, shot language, generation-prompt writing, and a pre-publish checklist. Apply it before producing on every line.
+---
+
+# video-craft
+
+The difference between a video that merely renders and one that's actually good. Apply these standards while scripting, storyboarding, composing, generating, and editing — and run the self-check before publishing. These are general production-craft norms; the exact numbers are starting points, adjust to the brief.
+
+## 1. The opening (hook)
+
+- The first **1–3 seconds** decide whether anyone keeps watching. Frame 1 must already carry motion or a text hook — no blank intro, no logo sting, no slow build.
+- Strong hook shapes: a sharp question, a counter-intuitive claim, the promised outcome ("by the end you'll…"), the stakes, or showing the finished result first ("here's what we'll build").
+- On muted autoplay the **on-screen text** is the hook — assume no sound for the first beat.
+- *Weak → strong:* ✗ "In this video we'll look at caching." (slow build, no stakes) → ✓ frame 1, bold on-screen text "Your API is slow. One line fixes it." (stakes + promised outcome, readable muted).
+
+## 2. Story structure
+
+- Arc: **hook → tension/gap → core idea(s) → proof/example → payoff/close (+ optional CTA)**. Land the first real payoff early; viewers drop off fast before they get value.
+- **One new idea per ~30–45 s** of explainer. A 3-min video carries 4–6 ideas, no more. Cut "interesting but irrelevant" — it actively lowers comprehension.
+- Connect beats with **"but" / "therefore"**, not "and then" — force logical (not just sequential) progression.
+- For teaching: show the naive idea, let it half-work, then break it and introduce the one key insight — people remember what they feel they discovered. Surfacing a common misconception first, then correcting it, beats stating the right answer cold.
+- Narration cadence: explainer **~150–160 wpm**, social/short **~180–200 wpm**, cinematic **~140–150 wpm**. Leave a **1–3 s** silence after a big reveal; avoid dead air > ~1.5 s between sentences.
+
+## 3. Pacing & timing
+
+- Shot/scene holds by format: explainer **~4–8 s**, short-form social **~1–3 s**, cinematic/contemplative **~10–20 s**. Don't hold the same length three times running — vary it.
+- Cutting energy: rapid (15–30 cuts/min) = urgency; moderate (8–15) = standard teaching; slow (3–6) = documentary calm.
+- A visual or audio **pattern interrupt** every ~20–30 s (short-form) / ~45–90 s (long-form) to re-grab attention.
+- Completion drops with length (15 s clips finish far more often than 60 s) — keep it as short as the message allows; don't pad.
+- Build animation timing **to the narration words**, not arbitrary beats. Hold a fully-built scene/chart **≥ 2–3 s** before moving on.
+
+## 4. Visual design
+
+- Composition: rule-of-thirds for key elements; center for stable establishing frames. One clear focal point per frame.
+- Palette: **≤ 3–5 colors on screen** at once. Background is the least-saturated; foreground (largest, most saturated, central) reads first.
+- Typography: **1–2 font families** total. At 1080p, titles ~60–90 px, body ~40–60 px, **never below ~40 px**; title at least ~50% larger than body. Max ~2 lines, ~32–42 chars/line.
+- **Safe zones**: keep text inside ~80% of the frame (~192 px margin at 1080p). For vertical, keep essential content out of the bottom ~300 px (platform UI sits there) and away from the very top.
+- Contrast ≥ **4.5:1** for any text (white-on-dark is safest). Use brightness/saturation, not red-green, to distinguish elements.
+- Consistency is a feeling of quality: one color grade/LUT, one type system, 2–3 transition types — for the whole video.
+
+## 5. Motion & animation
+
+- **Never linear easing** — it reads robotic. Default ease-in-out for moves, ease-out for entrances (settle in), ease-in for exits (accelerate away). Vary easing; don't repeat one three times.
+- Restraint: **one main element moves at a time**; stagger multi-element reveals by ~100–200 ms. A "static" shot means truly zero motion/zoom — if it moves, name the move.
+- *Weak → strong:* ✗ four cards fly in together, linear, all 0.3 s → ✓ stagger them ~120 ms, ease-out, each settling before the next starts (one focal point at a time).
+- Entrances ~0.3–0.5 s then hold for readable dwell; exits ~0.5–1 s. Optional small overshoot (~10–15%, settle in a few frames) adds life for playful pieces.
+- Kinetic type: reveal text to a readable dwell (~3 s per ~60 chars); word-by-word reveal synced to narration boosts attention.
+- Transitions carry meaning: **hard cut** = same topic/new angle (most invisible, most professional); **crossfade** = gentle topic change; **wipe/slide** = sequential steps; **zoom in/out** = into detail / out to context. Pick a small set and keep them consistent.
+
+## 6. Captions / on-screen text
+
+- Most social viewing is **muted** — captions are mandatory and are part of the pacing, not an afterthought.
+- Bold sans-serif, **≥ ~42 px**, ≤ ~2 lines, ≤ ~32–42 chars/line, with a dark stroke or semi-opaque backing for legibility on any footage.
+- Don't scroll text off before it can be read (~3 s per ~60 chars). Word-by-word highlighting in sync with the voice reads best.
+- Lower-thirds: speaker name bold + role lighter; enter ~1–2 s, hold a few seconds, exit fast; never cover eyes/mouth.
+- Don't make the viewer read on-screen text AND listen to different words at once.
+
+## 7. Audio
+
+- Pick music by energy: calm ~60–80 BPM, standard explainer ~90–110, upbeat ~110–130, high-energy ~120–140+. Use **instrumental** under narration (lyrics fight the voice); avoid big crescendos that bury speech.
+- Levels: narration peaks loudest; **duck music ~18–20 dB below speech**; SFX between. Master around **−14 LUFS**, true-peak ≤ ~−1 dB; never clip 0 dB.
+- SFX land **~10–20 ms before** the visual change they accent (ears lead eyes). Keep stacked SFX in different frequency bands.
+- Silence is a tool — drop music for a few seconds at a major reveal; let the moment land.
+
+## 8. Platform & format
+
+- Aspect: **9:16** (TikTok/Reels/Shorts), **16:9** (YouTube/web), **1:1** when speaker+context both matter, cinematic letterbox only when the look serves it. Don't center-crop a wide shot and call it vertical — reframe properly or downgrade to 1:1 honestly.
+- Get past the **3-second** threshold: hook in frame 1, change something every 1–3 s in short-form, captions always.
+- The **first frame is the thumbnail/promise** — design it deliberately as a cover, not as an accidental pre-animation state. It needs a readable promise plus concrete signals of the actual subject/result; make it match what you're delivering, and pay it off quickly.
+- Match length to platform norms; the algorithm rewards watch-time/completion, not raw length.
+
+## 9. Per-line craft — see the matching stage skill
+
+The cross-cutting craft above (§1–§8, §10–§11) applies to every line. The **line-specific director judgment** lives with each line's mechanics in its stage skill — read the one for the line you locked:
+
+- **Explainer / animation** → **stage-compose** (compose line).
+- **Talking-head, cinematic** → **stage-generate** (generation line).
+- **Social clip, podcast-repurpose, screen-demo, localization, documentary-montage** → **stage-edit** (editing line).
+- **A finished video woven from the user's material + framing / voice / motion (more than one line)** → **stage-plan** + **stage-assemble** (AUTO end-to-end line) — the cross-source editorial judgment: deciding the spine source-agnostic, assigning each beat the right source, and engineering continuity across the seams.
+
+If a piece layers lines (e.g. compose captions over generated footage), read both and apply the primary (locked) line's judgment first.
+
+## 10. Shot & camera language (generation / cinematic)
+
+- Move through shot sizes for flow: **wide (establish) → medium (develop) → close (emotion)**; avoid jumping wide-to-close without an intermediate.
+- Design each shot as a **first frame → last frame**; the motion bridges them. Each frame is a **static snapshot, never an action in progress** ("sitting, leaning forward", not "about to stand up"); the last frame is the logical result of the first frame + the motion. Big composition changes need an explicit camera move; small changes (expression, slight pose) stay in one framing.
+- **Reuse camera positions**; only introduce a new one when size/angle/focus genuinely changes. Keep relative positions stable across cuts (if a subject was left, keep them left); for two people talking, an over-the-shoulder pair plus a wider two-shot keeps geography clear.
+- Keep narrative/teaching shots steady and deliberate; reserve handheld / fast cuts / rapid zoom for action.
+
+## 11. Generation-prompt writing
+
+- Describe by **concrete visual features**, never by abstractions: "forest-green canvas jacket, short curly black hair" — not "professional, friendly". Adjectives like "warm" or "premium" don't constrain pixels; show them through appearance, light, and posture. Name the visual **cause** of a feeling, not the feeling ("wide aerial pull-back, lone figure against the rising sun", not "epic"); if you can't picture a specific photograph from the words, neither can the model.
+- *Weak → strong:* ✗ "a professional, friendly host in a modern office" → ✓ "woman, mid-30s, short black bob, charcoal blazer over white tee; sunlit open-plan office; soft window key from camera-left." Every adjective replaced by something the renderer can actually draw.
+- Specify **lighting + color temperature + style** (soft daylight / harsh noon / warm key; realistic vs cinematic) to anchor tone across shots.
+- For a shot, include shot size, (optional) lens feel (24/50/85 mm), camera move, and **which reference image governs which element** ("face from ref A, environment from ref B"). See the consistency skill for the character-bible + reference-selection method.
+
+## 12. Pre-publish review pass
+
+This is a **review**, not a checkbox sweep — read the draft as a skeptic hunting for what's wrong. Every issue you raise must name **where** and **the concrete fix** (change what, to what); if you can't name a fix, it isn't a finding yet — mark it "verify" and go look, don't leave a vague worry. Tag each finding:
+
+- **blocker** — ship-stopping (unreadable text, wrong aspect, missing hook, identity break, clipping audio). Fix before the final render.
+- **fix** — clearly hurts quality but not ship-stopping; fix unless out of scope.
+- **polish** — nice-to-have; note and move on.
+
+### Slideshow-risk gate (run before the high-quality render)
+
+The most common failure of generated/composed video is that it quietly degrades into a slideshow — stills with captions, no real motion or intent. Score the draft **0** (clean) / **1** (some) / **2** (bad) on each; treat any **2**, or an overall "this reads as a slideshow", as a **blocker**:
+
+- **Dead motion** — shots sit still: no camera move, build, or designed motion where the format wants it.
+- **Repetition** — same shot size / scene type / transition ≥ 3 in a row.
+- **Decoration** — motion or effects that carry no meaning (movement for its own sake).
+- **Promise drift** — a motion/cinematic brief silently delivered as static cards (see the routing lock).
+- **Text crutch** — walls of on-screen text doing the job the visuals should be doing.
+
+### Then confirm (each line = where a finding hides)
+
+- **Readable** — text ≥ the legibility floor (~40 px at 1080p, scaled to the canvas) and ≥ 4.5:1 contrast; captions synced; nothing covers the face/critical content; readable at phone size.
+- **Timed** — hook lands in the first seconds; first payoff early; pattern interrupt on cadence; each scene held long enough to read; narration wpm fits the format.
+- **On message** — the core point is actually stated; visuals reinforce (not fight) the narration; no padding/dead time; exact text correct (no hallucinated stats).
+- **Consistent** — one grade, one type system, a small transition set; subject identity preserved across cuts.
+- **Audio** — speech clear and loudest; music ducked; SFX slightly lead the cut; ~−14 LUFS integrated, true-peak ≤ ~−1 dBTP, no clipping/pops; silences intentional.
+- **Platform** — text in safe zones; correct aspect; length in range; first frame matches the promise.

+---
+
+# video-router
+
+Host-neutral knowledge for picking a video production line and locking it before work begins. This skill is read for guidance; it describes **what to decide**, not any host's tool mechanics.
+
+## Unavailable production runtime
+
+If the current system explicitly says that production tools, rendering, or
+paid operations are unavailable, routing still must produce useful work. For a
+clear or safely default-filled brief, select and state the line, then continue
+in the same response with a complete **unexecuted production package**:
+assumptions, script/narration, timed storyboard or shotlist, on-screen
+copy/captions, visual and audio direction, provenance/fallback assets, export
+target, preview-review checklist, and final QA checklist. Do not stop at a
+plan-confirmation form and withhold the package. Clearly distinguish
+planned files/media from produced files/media, and reserve future confirmation
+only for an operation the unavailable runtime would actually execute.
+Do not title the package “Production plan confirmation”. Make every timed scene
+production-usable with narration, exact visible copy/caption, visual action,
+and edit/transition instruction.
+For a narrated package, include the full verbatim caption line for every
+narration line; a short scene headline is additional on-screen copy, not a
+substitute for captions. Final QA must explicitly probe the produced file and
+verify it can be opened and played through after encoding, in addition to
+checking dimensions, duration, nonblank frames, captions, safe zones, and audio.
+The package language follows an explicit deliverable language in the request;
+otherwise it follows the current User UI language, with English only as the
+unsupported-or-unavailable fallback. Apply that language consistently to
+narration, exact on-screen copy, and captions even when benchmark or transport
+instructions are written in another language.
+
+## The three capability axes
+
+A finished video is built from one or more of three orthogonal axes. Decide which dominate, then lock them.
+
+- **Generate (A)** — AI-generated footage/imagery: photoreal shots, b-roll, motion, talking-head. Use when the brief needs real-looking or cinematic visuals.
+- **Compose (B)** — deterministic HTML composition: explainers, kinetic typography, motion graphics, captions / lower-thirds / overlays, data viz, title cards, transitions. Use when the visuals are designed rather than filmed. This is the default for explainer/animation work.
+- **Edit (C)** — intelligent editing of supplied footage: evidence-based selection/cleanup, deterministic cut/join/reframe/captions/audio work, and semantic AI video editing when the user requests a pixel-level change that timeline operations cannot make.
+
+## Decision rules
+
+1. Decide whether supplied video is the **edit target** or only a **production input** before choosing a line:
+   - When the user asks to change supplied video and the output keeps that footage or timeline as its spine, choose **Edit (C)**. Cuts, joins, reframing, captions, localization, deterministic overlays, and replacing or mixing audio—including supplied narration—remain edits of that video.
+   - A video used only as a reference, motion/timing guide, or one input in a newly authored timeline does not select EDIT. Neither do supplied images, narration audio, music, or scripts. Route the new deliverable by the production work it needs.
+   - Attachment type alone never decides the line. Ask whether to modify the existing video or make a new video from/reference it only when the requested output is genuinely ambiguous.
+2. Read the brief (topic, aspect ratio, language, duration) and classify the **dominant work object**:
+   - "explain / teach / animate / motion-graphics / kinetic text" → **Compose (B)** primary, optionally Generate (A) for b-roll.
+   - "make footage of / cinematic / a scene of / a character doing" → **Generate (A)** primary, Compose (B) to overlay captions.
+   - "cut / clip / trim / repurpose / make highlights / remove or change something in my video" → **Edit (C)** primary. Keep EDIT as the route even when one billable `operation:"edit"` video-model segment is required.
+3. Most explainer/animation requests are **Compose-primary**: typographic and motion-graphic scenes assembled as an HTML composition, with AI imagery only where a shot genuinely needs it.
+4. For supplied reference media, classify the requested relationship before choosing execution: `reproduce`, `edit`, or `guide`. Apply the same classification to images and videos regardless of which app, model, camera, or authoring format produced them. Images can control content/identity/composition/structure/style; videos can additionally control motion/timing/audio through temporal anchors.
+5. Aspect ratio drives the canvas: 16:9 → 1920×1080, 9:16 → 1080×1920, 1:1 → 1080×1080.
+
+## End-to-end (AUTO) — when the job spans lines
+
+Pick a **single line** when one axis cleanly dominates (just trim a clip; just an explainer; just generate a scene). Adding captions, supplied narration, localization, reframing, or a deterministic overlay while keeping the supplied video's timeline as the spine remains EDIT. Route to **AUTO end-to-end** only when the primary timeline genuinely weaves MORE THAN ONE axis:
+
+- "use my clip in the middle, author a full-frame motion-graphics opener, and add generated b-roll" (edit + compose + generate)
+- "my footage in the middle, generate an opener, compose the stats" (edit + generate + compose)
+- "make a finished video from these assets" where the assets alone are not the deliverable.
+
+AUTO does not abandon the axes — it sequences them through one cross-modal plan (`stage-plan` builds the EDL, `stage-assemble` walks it), delegating each segment back to the generate / compose / edit lines. Choosing AUTO is itself the lock: the *primary* still gets named via the plan's `delivery_promise` (source_led / motion_led / compose_led / hybrid).
+
+## Lock the runtime
+
+- Decide the primary axis at the brief/proposal stage and **state it in the proposal**.
+- Once locked, do not silently switch the primary axis mid-run. If a later step reveals the wrong choice, surface it to the user and re-confirm rather than quietly changing course.
+- Layering is fine and expected (e.g. Compose captions over Generated footage); "locking" governs the **primary** path, not the allowed overlays.
+
+## Runtime handoff
+
+For a fully specified one-shot deterministic EDIT, hand off directly to
+`stage-edit`: state the locked EDIT line, skip the direction artifact and plan,
+probe the source, and execute the requested operation. Load `stage-decide` first
+only when content or timing must be located from evidence.
+
+For every other job with the production runtime available, routing ends at the
+direction boundary, not at a production plan. For a Chinese UI, use the exact
+gate-control title `制作方向确认` (never `创意方向确认`) and show only two or three
+direction concepts plus the facts already locked by the brief. Do not write a
+manifest, script, narration copy, or art direction before that choice. End the
+direction question with `<plan-interaction status="open" />` — without it the
+runtime reads the stop as an unfinished turn and bounces the reply.
+
+## Boundary / non-goals
+
+This skill only routes and locks. It does not author compositions or execute edits. Semantic editing is not a silent switch to GENERATE: it remains an EDIT/AUTO job whose EDL contains a signed, billable video `operation:"edit"` segment with the original reference video and preservation boundary.
+
+The native VideoStudio lines are the only production path. Never substitute an
+outside video framework for a missing native component. If a required component
+is unavailable, say plainly which component is missing and stop rather than
+inventing a replacement pipeline.

+description_en: Map the locked storyboard, layout grammar, and visual system to one complete create_pptx call that produces visually focused, native-editable, reviewable slides; existing decks receive only minimal element-path edits.
+---
+
+# PPT Craft
+
+Read this skill only when an actual PPTX will be created or changed. Read the shared `office-ppt` Skill before the first PPTX tool call.
+
+## Execute the visual source
+
+Honor the resolved visual source before choosing slide geometry:
+
+- `autonomous`: treat the planner's audience- and content-derived visual DNA as a complete design source. No reference file is required, and the result must still use purposeful backgrounds, visual hierarchy, media/data treatments, and content-led composition rather than falling back to plain title-and-bullets pages.
+- `text-direction`: construct from the interpreted visual DNA without claiming an exact match to an external brand or designer.
+- `reference-image`: use the declared palette behavior, canvas, type character, geometry, image treatment, and motifs. Do not copy the image's exact composition or reuse the pixels unless `reference_asset_reuse: allowed`.
+- `reference-deck` with `inspiration`: inspect the source deck, then rebuild the relevant design language with supported native objects. Map each output slide to a reference role or visual-DNA trait, not necessarily to an exact source page.
+- `reference-deck` with `template-source`: inspect the source with `office_read` and current renders before mutation. When the requested result can be expressed through supported edits, use the authorized PPTX as the source for one separate working copy, preserve its masters/layouts/theme, and fill or adapt identified elements. Do not overlay a parallel default design. If strict template fidelity requires unsupported master/layout or duplication operations, report that boundary rather than silently switching to a vibe-matched rebuild.
+- `existing-deck`: follow the source-preserving edit path below.
+
+Before reference-led construction, make the inspection evidence explicit:
+
+- inspiration deck: structurally inspect every source slide, then render enough
+  source slides to cover opening, section, data, close, and every recurring
+  layout family before locking the extracted visual DNA;
+- strict template: structurally inspect and render every source slide before
+  mapping each requested output role to an inherited source pattern.
+
+These are required evidence steps, not optional review detail. When execution
+is unavailable, state this complete unexecuted coverage in the production
+specification instead of shortening it to “inspect the reference”. Do not claim
+that either inspection occurred. Keep source-reference renders distinct from
+output-deck renders: rendering every new slide does not prove that the source
+reference families were visually inspected, and rendering the source does not
+replace structural validation plus rendered review of every new output slide.
+
+A strict-template result must contain the exact requested output slide count.
+Select, duplicate, or remove source patterns only through supported path-based
+operations. Do not keep unused template slides in a requested six-slide result;
+if the exact count cannot be produced without unsafe structural mutation, report
+that blocker instead of claiming a complete six-slide deck.
+
+When the user explicitly supplies slide titles, labels, or page order, treat
+those strings and that order as a verbatim content contract. Do not rename them
+to satisfy autonomous assertion-title preferences. Before publication, read the
+current output slides and compare every contracted string and position against
+the request; repair any omission, substitution, or reordering before handoff.
+
+User instructions and authorized reference/brand material outrank autonomous defaults. Reference fidelity is scoped by `keep`, `adapt`, and `do_not_copy`; it never authorizes copying unsupported claims, third-party logos, proprietary illustrations, or unlicensed assets.
+
+Do not make missing factual copy a construction blocker when the user has
+already authorized a draft. Use neutral editable placeholders or visibly
+labeled assumptions in the planned slots, keep unsupported claims out of
+assertion titles, and continue through the chosen reference-safe route. Ask
+only when a source role, destructive change, or strict-fidelity decision is
+actually unresolved.
+
+## Scratch new editable deck
+
+Use `create_pptx` as the only initial construction route. Call it exactly once with the complete slide array and `preview:false`; accept the exact path it returns, including a collision-safe rename. Call `office_review` once on that exact path with `action:"check_and_render"`, every required initial slide in `pages`, and `analysis_mode:"quality_review"`; invalid structure stops the render phase, while a valid result returns the collected image set for `ppt-review`. In the first response that receives this image batch, write one concise page-specific evidence sentence before loading `ppt-review` or making any other tool call. That sentence must record the reviewed pages, concrete pass/defect observations, and the next action. Loading review guidance never justifies rendering the same page at the same `artifact_revision` again: use the persisted sentence for unchanged pages, and after an edit rerender only affected pages. The create call's first-slide preview must not start visual review ahead of structural validation. Do not create one slide at a time, issue a second create call for the same deck, or use shell/file tools to copy or rename the result. Source-reference renders used only to understand a visual language use `office_review` with `action:"render"` and the default `analysis_mode:"understand"`; defect checking is an explicit output-review operation.
+
+Map every storyboard card to supported native objects:
+
+- `title` and `body` for simple layout-driven pages;
+- `shapes` for assertion titles, panels, labels, dividers, diagrams, timelines, processes, and simple data visuals;
+- `images` only from sandbox-allowed local paths for photography, illustration, screenshots, or supplied brand assets;
+- `charts` for supplied or approved quantitative comparisons, distributions, and ordered series that must remain natively editable;
+- `tables` for comparison, schedule, responsibility, metric, or appendix grids;
+- `background` and restrained `transition` only when the plan calls for them.
+
+Before the create call, run a construction preflight over the complete slide array. Block only mechanical or presentation-integrity failures: a missing required slide, unsupported remote asset, quantitative encoding that does not map to supplied or approved values, missing primary content, unreadable intended text, or an object expected to exceed the canvas. Scan every visible string: any numeral, percentage, duration, rank, benchmark, or source-claim phrase such as “according to research” must map to supplied or explicitly approved evidence, be visibly labeled as an assumption, or be rewritten as qualitative/editable placeholder copy before the tool call. The plan's own artifacts are not deck content: the evidence boundary, the brief, acceptance criteria, and any statement of what you were told not to do belong to the author, not the audience. Attributing a source is content — “数据来源：metrics.csv” earns its place; declaring the rule you followed is not — “only facts from these two files” and “no external data was added” say nothing a reader can act on. Remove those strings before the tool call. Treat color count, accent area, layout repetition, cards, gradients, radii, density rhythm, and use of `custom` geometry as design observations, not construction blockers.
+
+On a 16:9 canvas, translate the working alignment logic and practical primary-content safe zones into explicit coordinates. An unbranded `0.60–0.75in` inset is a useful starting range, not a fixed frame; authorized references, intentional media bleed, and optical composition may use different geometry. Establish a few strong alignment lines per slide. Use either placeholders or free-positioned shapes as the primary layout system in a region; do not accidentally stack both there. When both systems are intentional, give them explicit roles and non-conflicting geometry. Do not infer a construction failure from equal strings alone: repeated wording can be intentional, while accidental overlap or redundant visual hierarchy must be decided from the intended role and current render. Reserve placeholders for genuinely simple or template-led pages; designed content pages may use named free-positioned objects.
+
+Build in visual layer order: background, structural regions, media/chart/diagram, primary takeaway, supporting labels, then source/footer. Compose the background as part of the page rather than treating it only as a color token: use a quiet field, structured color region, image-led field, restrained gradient, grid/line language, subtle texture, or another reference/content-led treatment when useful. Keep primary audience-facing text inside a readable zone while allowing intentional image or decorative bleed.
+
+Make the planned visual focus obvious at a glance. A dominant region around 30–55% of the usable canvas is a useful starting range, not a validation threshold. Keep titles concise, preserve a legible hierarchy, and never solve overflow by shrinking all text. Use whitespace, scale, alignment, image crop, and contrast before decoration.
+
+Treat fill opacity as a modifier, not a standalone style. Add `opacity` only
+when the same shape has an explicit `fill`, `gradient`, or `pattern`; add
+`lineOpacity` only with an explicit `line`. An unfilled text box needs neither
+property, and orphan opacity modifiers can invalidate an otherwise complete
+Office batch.
+
+Choose, adapt, or bypass layout recipes according to the communication job—hero statement, editorial split, process, comparison, data story, image-led page, close, or a custom composition. Recipes define relationships and content capacity, not fixed templates. Repeating a strong geometry is appropriate for a sequence, comparison, recurring case pattern, or source-template rhythm; vary it only when the story benefits. Equal-weight cards are useful for genuinely parallel information but should not become an accidental universal layout. Treat excessive pills, decorative gradients, ornamental icons, fake dashboards, and arbitrary style changes as warnings that require visual judgment, not automatic rejection rules.
+
+Use raster images for photographic or illustrative content, not for text, labels, tables, diagrams, or the entire slide. Follow each page's asset plan: role, source, aspect ratio, crop, focal point, and treatment. Crop intentionally to support the composition; do not stretch. Preserve attribution, source notes, and useful alternative text. Never pass remote URLs as image paths or claim an image right that was not established. Use image generation only when the available image tool, user authorization, and asset plan allow it. When no suitable asset exists, adapt the layout to a native typographic, chart, table, or diagram composition instead of inserting a decorative placeholder.
+
+Use native charts for supplied or approved numeric data. Choose the chart for the communication job—bar/column for comparison, line/area for an ordered series, scatter for relationship, waterfall for a supplied contribution breakdown—and remove unnecessary chart furniture. Keep categories, units, period labels, data labels, legend, and source legible. Preserve the provided category/series mapping and status labels; never invent a value to make a chart look complete. Use one value-label system: do not place manual value labels over chart-native data labels. A current render with duplicated labels, label-to-point misalignment, or label collisions is a repair defect, not decoration to accept. If a simple labeled-shape diagram communicates better than a chart, use the simpler visual.
+
+The current creation contract supports native text, shapes, pictures, charts, tables, backgrounds, and transitions. It does not establish SmartArt, animation sequences, speaker notes, or master/layout authoring. Disclose those limits instead of flattening or fabricating support.
+
+## Existing or authorized template PPTX
+
+Protect the supplied source:
+
+1. Use `office_read` with `outline`, `query`, or `get` to identify the exact slide and element paths.
+2. Translate the authorized change into the smallest `set`, `add`, or `remove` operation batch.
+3. Pass the pre-existing source to `edit_office`; set `output_path` in that call when a specific final name is required. Let the tool create the separate validated working copy.
+4. Do not guess shape indexes, globally replace text without enumerating affected elements, or rebuild an existing slide as a picture.
+
+Preserve masters, layouts, theme, notes, charts, media, relationships, and transitions unless the user explicitly requests a supported change. If a requested feature is visible but not safely addressable through returned paths and supported operations, leave it intact and report the boundary.
+
+For a template source, distinguish inherited visual furniture from editable content. Prefer identified placeholders and existing component slots. Do not flatten the template, erase all text-bearing objects by heuristic, or place a second visual system over inherited elements. If the source lacks a usable pattern for requested content, either adapt the nearest authorized pattern within supported operations or, when the declared reference strength permits inspiration, create a scratch deck from the extracted visual DNA. Never switch modes silently.
+
+After the template edit, use `office_read` on the output—not only the source—to
+verify exact slide count, contracted page order, verbatim user-supplied titles
+and labels, and the absence of unused template residue before visual review.
+For each requested object-level style change, reread the same returned object
+path on the output and repair it if the requested properties do not match.
+
+## Repair after creation
+
+If `ppt-review` finds a defect in a deck produced in this conversation, use `office_read` to locate the exact target and `edit_office` to refine the exact returned artifact. Do not restart with `create_pptx`, fork a second draft, or patch OpenXML directly. Each repair batch must correspond to concrete validation or render evidence.
+
+Hand the exact final-candidate path to `ppt-review`; construction is not complete merely because the create or edit tool returned successfully.
+
+## Generated-deck handoff audit
+
+Before publishing a generated deck, prepare exactly one row per slide in page
+order. Use this literal shape and these exact status tokens:
+
+`P1 | Content: PASS — evidence | Design: WARNING — evidence | Coherence: PASS — evidence`
+
+Replace the page number, status, and evidence from the current render, but keep
+the labels `Content`, `Design`, and `Coherence` and use only `PASS`, `WARNING`,
+or `BLOCKER`. Do not substitute unlabeled prose such as “完整、清晰、正常” for
+the status fields. Count the rows before `publish_outputs`; every generated page
+must appear exactly once, and any `BLOCKER` must be repaired before publication.

+
+# PPT Planner
+
+Read only after `ppt-router` chooses `CREATE` or `OUTLINE`. Planning is the source of truth for construction, not optional prose around the deck.
+
+## 1. Presentation brief
+
+Lock these fields from the request and inspected materials:
+
+- audience and decision, learning, sales, or communication job;
+- desired audience action or takeaway;
+- language, slide-count range, tone, and content density;
+- source boundary: supplied-only, supplied-plus-current-research, or clearly labeled draft assumptions;
+- must-include, must-avoid, confidentiality, brand, and template/reference constraints;
+- delivery format and aspect ratio; default to editable `.pptx` and 16:9 when unspecified.
+
+When the user explicitly supplies slide titles, labels, or an ordered page
+list, record those visible strings and their order as a verbatim content
+contract. Do not improve, synonymize, shorten, or replace them with autonomous
+assertion titles. Assertion-title guidance applies only where the user did not
+fix the visible wording.
+
+Ask only when a missing answer would change the deck's purpose, evidence boundary, or deliverable. Otherwise choose a sensible default and record it.
+
+## 2. Visual source and references
+
+Resolve one visual source before choosing an art direction:
+
+- `autonomous`: no visual reference exists. This is a normal, complete path. Do not ask the user to find a reference and do not reduce the deck to a generic title-and-bullets template. Derive a suitable visual character from the audience, communication job, subject matter, tone, and available evidence.
+- `text-direction`: translate the user's words into a usable visual system without inventing a named brand or claiming an exact external style match.
+- `reference-image`: inspect every supplied reference image and extract only the relevant visual signals: palette hierarchy, canvas/background treatment, typography character, grid and alignment, whitespace, dominant-object scale, image crop/focal point, surface treatment, and recurring motifs. Record uncertain inferences as low confidence. A reference image is not a reusable slide asset unless the user supplied or authorized it for reuse.
+- `reference-deck`: decide whether the PPTX is `inspiration` or an authorized `template-source`. Inspect all source slides structurally. For strict template following, also render and inspect every source slide before mapping output roles to reusable source patterns; for inspiration, render enough slides to cover every recurring layout family and the opening/section/data/close roles. Extract theme colors, font evidence, margins, alignment lines, background language, image treatment, chart/table treatment, recurring furniture, and slide-role patterns.
+- `existing-deck`: preserve its current visual system unless the user authorizes a bounded redesign.
+
+Reference material is production input, not a routine clarification trigger.
+When its role is explicit, inspect it before requesting optional business copy.
+If the deck topic, customer facts, product proof, or quarterly values are still
+missing, complete the structure with neutral titles and visibly labeled
+placeholders or assumptions. Do not end with “send these details and I will
+start”; the reference interpretation, story skeleton, visual system, and
+production route can all be completed safely first.
+
+If tools are unavailable, distinguish observed evidence from planned evidence:
+never claim that a reference was inspected, but still return a self-contained
+unexecuted specification naming what will be inspected, which visual-DNA fields
+will be extracted, how each output page will adapt them, how the source remains
+unchanged, and what structural and rendered evidence will be reviewed. Use
+plain presentation language rather than private tool names.
+
+Do not fill an uninspected reference-image record with a plausible palette or
+named art direction based on the deck topic. Mark palette, typography,
+background, geometry, crop/focal behavior, and motifs as pending reference
+inspection. If a construction-ready fallback is useful, label it explicitly as
+a provisional autonomous fallback, not as evidence extracted from the image.
+
+Record this compact interpretation:
+
+```yaml
+visual_source: autonomous|text-direction|reference-image|reference-deck|existing-deck
+reference_mode: none|inspiration|brand-source|template-source|editable-source
+reference_strength: loose|balanced|strict
+reference_asset_reuse: allowed|reference-only|unknown
+visual_dna:
+  character: "visual personality appropriate to the communication job"
+  palette_behavior: "dominant, support, accent, and semantic-color behavior"
+  canvas: "background composition and whitespace behavior"
+  typography: "hierarchy and typographic character; exact family only when evidenced"
+  geometry: "grid, alignment, scale, and spacing tendencies"
+  imagery: "subject, crop, focal point, ratio, and treatment"
+  motifs: []
+  avoid: []
+confidence: high|medium|low
+```
+
+References control only their declared role. Record `keep`, `adapt`, and `do_not_copy`. Do not copy third-party logos, unique illustrations, proprietary claims, or exact layouts without authorization. User instructions and authorized brand/reference material override autonomous defaults; narrative clarity and source fidelity still take precedence over irrelevant reference structure.
+
+A known authoring limitation does not require pretending that source inspection
+already occurred. When the user requires an unsupported feature with exact
+fidelity, state the limitation and preserve the source immediately. Inspect or
+render the source only when that evidence can identify a supported preservation
+path or user-selectable alternative; do not perform ceremonial inspection merely
+to restate a capability boundary that is already known.
+
+## 3. Content boundary
+
+Inspect supplied material before outlining and separate user-provided content,
+explicit draft assumptions, and missing copy. Preserve the visible meaning of
+supplied wording, figures, labels, units, dates, page order, and status labels.
+PptMaker does not independently verify business truth or infer missing domain
+definitions unless the user explicitly asks for research or analysis.
+
+Do not invent source facts merely to complete a layout. Use a neutral editable
+placeholder, a question, or visibly labeled draft copy when a requested slide
+role lacks content. Keep source labels where the user supplied them or where
+they are needed to distinguish supplied material from draft presentation copy.
+An assertion-style title must summarize the content shown on that slide rather
+than introduce an unsupported claim or contradict the body.
+
+## 4. Narrative outline
+
+Build one argument, not a list of topics. Select a structure that fits the presentation job, such as situation-complication-resolution, problem-evidence-choice, before-after-bridge, lesson-concept-example-practice, or context-progress-risk-decision.
+
+Convert every user-specified content role into a coverage checklist before
+outlining, then map each role to at least one slide. Do not silently replace a
+requested use-case page with capability pages, a requested risk page with a
+generic problem page, or another named role with a nearby topic. Run the
+coverage checklist again before returning the storyboard.
+
+For a product-introduction use-case page, include at least three concrete
+actor–task–result examples (for example, who supplies what input, what the
+assistant does, and what editable or reviewable result is produced). Category
+labels such as “documents, meetings, and knowledge” alone are not use cases.
+
+For an enterprise product-introduction deck, reserve a distinct slide for
+customer value and expected outcomes. Keep its outcomes qualitative or visibly
+labeled as hypotheses when proof is missing, and state what pilot evidence or
+measurement would validate them. Do not bury customer value inside a capability,
+security, implementation, or closing page merely to satisfy the word “value”.
+
+Each slide gets one primary takeaway. Prefer assertion-style titles that state the conclusion, except for covers, section dividers, agendas, neutral reference pages, and titles whose visible wording the user fixed verbatim. The sequence must explain why each slide follows the previous one and what question it answers.
+
+Do not add a filler slide merely to reach the requested count. An overview,
+bridge, decision, or close is useful only when it has a distinct audience job;
+do not repeat the previous target, chart, or action list under a new title. If
+the source content is sparse, use a purposeful navigation, synthesis, or next-
+step role with visibly bounded content instead of duplicating another page.
+
+## 5. Slide storyboard
+
+Create one card per slide:
+
+```yaml
+slide: 1
+role: cover|agenda|context|argument|evidence|comparison|process|decision|appendix
+takeaway: "one sentence"
+evidence: ["source or assumption label"]
+pattern: cover|hero-statement|editorial-split|timeline|process|comparison|data-story|image-led|quote|close
+layout_mode: recipe|adapted|custom
+visual_focus: "the single dominant object or contrast the audience notices first"
+visual_encoding: "native shapes, editable chart, styled table, diagram, or local image"
+background_intent: "plain canvas, structured field, image-led field, texture, or another purposeful treatment"
+reference_anchor: "reference page/image/design-DNA trait or autonomous"
+asset_plan: "hero/evidence/context/decorative role, source, ratio, crop, and focal point; or none"
+content_budget: "title, body word count, item count, and source-note allowance"
+continuity: "link from previous and to next slide"
+```
+
+Every content slide needs one semantic visual focus. A visual focus explains, compares, proves, or sequences the takeaway; it is not decoration. Use an editable native chart for supplied or approved quantitative comparison or trend data, with the relevant labels, unit, and source visible. Do not prescribe SmartArt, animations, master edits, or speaker notes.
+
+## 6. Adaptive design lock
+
+Choose one coherent art direction that fits the audience and message. When the user supplies no brand, reference, or style, choose the best-fit direction autonomously and continue; a missing visual reference is not a blocker and does not require a preference question. Supported starting directions include, but are not limited to:
+
+- `Swiss editorial`: strict grid, strong type hierarchy, restrained color, high whitespace;
+- `editorial analysis`: oversized assertion, annotated evidence, asymmetric split, quiet surfaces;
+- `product showcase`: dark or light product stage, cropped UI/photo, benefit-led callouts;
+- `data journalism`: annotated native charts, source-forward labels, minimal chart furniture;
+- `photo-led`: one strong licensed/supplied image with disciplined text overlay or split;
+- `technical blueprint`: modular diagrams, connectors, numbered steps, precise labels.
+
+These are starting points, not a closed style menu. Do not force every unbranded enterprise deck into `Swiss product editorial` or a fixed blue palette. A product launch, investor narrative, teaching deck, technical proposal, cultural topic, or image-led story may require a different autonomous direction.
+
+Lock only the decisions needed to construct a coherent first draft; keep aesthetic values adaptable:
+
+- canvas and aspect ratio (`13.333in × 7.5in` for default 16:9), plus practical safe zones for primary content rather than a universal decorative boundary;
+- working alignment logic: a grid, asymmetric split, optical alignment, or reference-derived geometry with named anchors;
+- an exact working palette for construction, derived from authorized references when present or selected autonomously when absent. Color count, accent area, and background variation are guidance, not publication gates;
+- target-safe fonts and working size anchors appropriate to the reference and audience. Suggested unbranded ranges are cover `32–44pt`, slide title `26–32pt`, body `17–20pt`, label `11–14pt`, and source `9–10pt`, but reference fidelity, language, and rendered legibility decide the actual values;
+- a canvas language covering purposeful background treatments such as quiet fields, structured color regions, image-led fields, restrained gradients, grids/lines, or subtle texture;
+- component and media behavior for whitespace, line/border treatment, connectors, charts, image ratios, crop, focal point, and source labels;
+- enough purposeful layout variation for the narrative. There is no numeric layout-family minimum, and repeated geometry is acceptable when it strengthens a sequence, comparison, or reference-template rhythm;
+- explicit anti-patterns relevant to this deck, such as unreadably small primary text, accidental UI-card walls, unlicensed imagery, fake screenshots, or style drift.
+
+Treat contrast ratios, color-count heuristics, density rhythm, layout repetition, accent proportions, cards, gradients, radii, and whitespace targets as diagnostic guidance. They may trigger an adaptation or warning, but must not override the user's authorized reference, brand system, or a deliberate content-led composition. Primary audience-facing text must still be readable in the final render.
+
+For each page, choose a layout recipe, adapt one, or use `custom`. Recipes describe useful relationships and content capacity, not mandatory templates. A custom page is valid when its hierarchy, asset availability, and primary reading order are explicit.
+
+## 7. Build-readiness gate
+
+Do not hand a new deck to construction until all are true:
+
+- every slide has a takeaway, visual intent, evidence label, bounded content budget, background intent, and an asset plan or an explicit no-asset composition;
+- the visual source is resolved, including an autonomous visual DNA when no reference exists;
+- one usable art direction, exact working palette, typography hierarchy, canvas/alignment logic, and image/chart treatment are available for construction;
+- reference roles, reuse permission, confidence, and `keep` / `adapt` / `do_not_copy` boundaries are explicit when references exist;
+- every quantitative visual maps to supplied or approved values, labels, units, categories, and a source;
+- no page depends on an unsupported feature or a remote image path.
+
+Do not reject a build merely because it uses an unusual color count, repeats a successful layout, chooses a custom composition, or lacks an external visual reference. Those are design-review observations, not construction blockers.
+
+## 8. Planning-only visible output contract
+
+When the requested deliverable stops at an outline, storyboard, or production
+plan, make the locked decisions visible instead of returning only topical slide
+titles. The response must be usable by a different slide builder without
+guessing. Use ordinary presentation language and include:
+
+1. one short opening sentence that says what is being organized now and what
+   the next production step would be;
+2. the audience, decision/action, evidence boundary, and total slide count as
+   explicit values;
+3. a `视觉方案` block with `自主设计 / 文字方向 / 参考图 / 参考 PPT` as the
+   visual source, the named art direction and reasoning, visual-DNA summary,
+   exact working palette, point-size anchors, canvas/alignment logic,
+   background language, crop/chart treatment, and reference reuse boundary;
+4. a numbered card for every slide containing its takeaway, semantic visual
+   focus, layout mode, background intent, asset plan, reference anchor,
+   evidence label, and content budget;
+5. a final deck-rhythm line explaining how repeated and varied silhouettes
+   support the story. Do not invent a numeric layout-family quota, density
+   sequence, or repetition ceiling merely to satisfy the plan format.
+
+Density labels such as `信息较少 / 信息适中 / 信息较多` are optional planning aids.
+Use them only when they help explain pacing; their presence, alternation, or
+count is not a quality gate.
+
+Also show a one-line must-include coverage check. If a requested slide lacks
+content, use a visible neutral placeholder or explicitly labeled draft copy
+rather than relying only on a preamble or footer disclaimer.
+
+For a data presentation, add a compact `信息与图表映射` block. Copy every supplied
+value, label, unit, period, and category that will be visible; keep user-provided
+status labels such as actual, target, forecast, sample, or placeholder visually
+distinct; and name the native editable chart or other visual form for each data
+group. Specify category/series mapping, label placement, annotation behavior,
+unit, source note, and a zero baseline for bar or column comparison unless the
+page explicitly explains another choice. Write the bar/column baseline decision
+explicitly in the visible plan rather than treating it as an implied chart
+default. Do not make the audience reconstruct these mappings from slide notes.
+
+PptMaker may format user-provided conclusions and calculations, but it should
+not invent a new derived metric or business conclusion merely to fill a page.
+When the requested presentation needs content that was not supplied, reserve a
+clearly labeled editable placeholder or describe the missing content input. This
+is a presentation-fidelity boundary, not an instruction to audit the external
+truth or business reasonableness of the source material.
+
+Give each slide a distinct communication job. Do not spend adjacent pages
+restating the same information with a second decorative chart; combine closely
+related annotations or use the next page for a different comparison, action,
+or decision role.
+
+Before returning a planning-only answer, perform a text-level completeness
+check against these visible fields. Do not expose private route/depth codes,
+skill names, tool names, or YAML workflow metadata while doing so.
+The storyboard is already the execution plan for an `OUTLINE` request; do not
+create or update a separate runtime execution plan. Return the complete visible
+storyboard directly in this turn.
+
+## Planning handoff
+
+For QUICK work, return a compact brief, outline, storyboard, and design lock in the working context. For STANDARD decks with more than eight slides, multiple sources, or likely context continuation, also save a compact `ppt-plan.md` in the workspace so later repair can recover the approved direction.
+
+If the route is `OUTLINE`, stop with the requested planning layer. If the route is `CREATE`, hand the locked plan to `ppt-craft` without silently changing its audience, evidence boundary, takeaways, or visual system.

+description_en: After structural validation and per-slide renders exist, diagnose slide aesthetics, reference fit, and whole-deck narrative rhythm, then repair concrete evidence-based defects from current evidence.
+---
+
+# PPT Review
+
+Read this skill only after current `office_review` structural output and relevant rendered images exist. Do not use source code, a tool success flag, or the first-slide preview as a substitute for deck evidence.
+
+## Evidence set
+
+- Run `office_review` with `action:"check_and_render"` after every create or edit. Invalid OpenXML is a blocker, not a warning.
+- For a new deck, render every slide. For an existing deck, render every changed slide plus the cover, a representative unchanged content slide, and any slide whose theme, master, or shared element could be affected. Every render intended as current visual-defect evidence must set `analysis_mode:"quality_review"`; ordinary source understanding keeps the default `understand` mode.
+- After a repair affects multiple pages, request them together in one `office_review` call with `action:"check_and_render"`, a `pages` array, and `analysis_mode:"quality_review"`. One collected image set lets managed visual preprocessing analyze the affected pages as a batch. If one render fails after a valid check, retry only that page with `action:"render"` rather than rerendering the successful set.
+- Rendered image blocks are transient after the next assistant response. In the first response that sees each collected `quality_review` image set, write one concise plain-language evidence sentence before any follow-up tool calls: name the reviewed pages, concrete pass/defect observations, and the next action. This sentence is the durable visual-review state for later tool rounds and compaction. When exact edit paths are needed, request the targeted `office_read` calls together in that same response; do not rerender an unchanged `artifact_revision` merely to recover forgotten pixels.
+- Use the returned `artifact_revision` to distinguish current from stale check/render evidence and `image_revision` to compare rerenders. If an edit claimed to repair a visible defect but the affected page keeps the same `image_revision`, do not claim a visual repair: verify that the edited artifact revision was rendered, then make a supported layout/content change or retain the finding as unresolved.
+- If rendering is unavailable, mark visual checks `not_run`; do not infer a pass from structural validity.
+
+## Two review layers
+
+Review every required render at slide level, then review the contact-sheet-like sequence as a whole. A slide can be individually tidy while the deck still fails because every page repeats the same card grid or the visual language drifts.
+
+### Per-slide review checklist
+
+Mark each item `PASS`, `WARNING`, or `BLOCKER` and attach a concrete observation from the current render. Do not derive a result from intent, source code, or self-description.
+
+- `intent_fit`: the visual form makes the slide's takeaway easier to understand;
+- `hierarchy`: the first, second, and supporting reading order is unmistakable;
+- `composition`: focal point, balance, alignment, whitespace, and safe margins work together;
+- `typography`: type scale, line length, wrapping, density, and CJK rendering are presentation-legible;
+- `color_contrast`: palette is coherent and primary audience-facing text is readable in the current render;
+- `visual_usefulness`: chart, diagram, table, or image explains rather than decorates.
+
+For every chart, also verify from the current render that each visible value label
+maps to one data point, appears only once, and does not collide with another label,
+axis, or series mark. Duplicated manual and native labels, label-to-point
+misalignment, and collisions are concrete repair defects even when the underlying
+series values are correct.
+
+When a visual reference exists, also record `reference_fit`: the result follows the declared `keep` and `adapt` traits without copying `do_not_copy` material. Do not mark an intentional, authorized deviation as a defect merely because it differs from an autonomous default.
+
+Checklist results are diagnostic evidence used to find the weakest pages and prioritize repairs. Use `BLOCKER` only for a concrete delivery failure such as clipped or unreadable primary content, an unsupported or materially false claim, invalid structure, or a requested reference/template requirement that was not met. Otherwise classify a supported defect as `WARNING` and improve it when a proportionate edit is available. Never invent a numeric aesthetic score or average.
+
+### Whole-deck review
+
+- layout rhythm supports the narrative; there is no numeric family minimum or repetition ceiling;
+- repeated geometry is coherent when it supports a series, comparison, recurring case, or reference-template rhythm, and mechanical when it obscures different communication jobs;
+- density changes are intentional when useful, without requiring a prescribed sparse/dense alternation;
+- background modes may vary when they serve a section, slide role, or semantic
+  emphasis. Unexplained mechanical dark/light alternation or an isolated theme
+  switch is a `WARNING` to record and repair, not an automatic blocker;
+- equal-card grids communicate genuine parallelism rather than appearing by default;
+- cover, opening, evidence, decision, and close feel intentionally designed for their roles;
+- charts, image treatments, sources, page numbers, and recurring elements stay consistent.
+
+When the same weakness recurs across multiple slides or a shared component, repair the underlying token, component, or layout pattern rather than nudging each page independently. After repair, rerender every affected slide and repeat the whole-deck pass.
+
+## Three-dimensional review
+
+Use the checklist and whole-deck evidence to complete the broader quality review below.
+
+For a review-only request, make the report independently actionable. Cover every
+reviewed slide and label each finding `Content`, `Design`, or `Coherence` plus
+`BLOCKER`, `WARNING`, or `PASS`. Each non-pass finding must name the current
+evidence, user impact, and smallest supported repair. Across the report, include
+at least one explicit evidence-based result for each of the three dimensions;
+do not collapse them into generic deck-level praise or a list of unlabelled
+suggestions.
+
+### Content
+
+- The deck answers the brief and ends with the intended decision, action, or learning outcome.
+- Each slide has one dominant takeaway and all supporting copy serves it.
+- Claims, values, dates, labels, units, and sources match the evidence boundary.
+- Explicit user-supplied slide titles, labels, and page order match the current
+  output verbatim. A missing, renamed, synonymized, or reordered contracted
+  string is a `BLOCKER`, even when the substitute reads more editorially.
+- Supplied content has not been expanded into invented source facts merely to
+  fill a layout; missing copy remains a neutral placeholder or visibly labeled
+  draft rather than being presented as user-provided material.
+- Placeholders, template residue, accidentally duplicated or overlapping text, broken glyphs, and unsupported promises are absent. Repeated wording in intentional, distinct roles is not a defect by itself.
+- Tables and simple data visuals preserve the supplied category/series mapping and status labels, remain legible, use one non-colliding value-label system, and include the relevant period label, unit, and source.
+
+### Design
+
+- No primary content is clipped, overflowing, obscured, outside safe margins, or too small to present.
+- Alignment, spacing, hierarchy, contrast, image crop, and text wrapping are intentional.
+- The locked palette, typography roles, grid, and visual grammar remain consistent.
+- When references exist, the result respects their declared role and reuse boundary; when they do not, the autonomous visual direction remains coherent and fully designed.
+- Images are sufficiently clear and not stretched; raster content does not replace editable text or diagrams.
+- Density matches the brief, and decoration does not compete with the message.
+
+### Coherence
+
+- Slide order forms an understandable argument, not a set of independent pages.
+- Titles, terminology, numbers, tense, voice, source style, and layout rhythm are consistent.
+- Transitions between sections are clear, and repeated information is deliberate.
+- Cover, opening, evidence, decision/close, and appendix roles match the outline.
+
+## Findings and repair
+
+Classify each finding:
+
+- `BLOCKER`: invalid OpenXML, missing/blank required slide, clipped or unreadable primary content, unresolved placeholder/template text, a material unsupported claim, or a deliverable that is not an editable PPTX when one was requested.
+- `WARNING`: visible but non-blocking density, hierarchy, consistency, image-quality, source-placement, or target-viewer risk.
+- `PASS`: supported by named structural or render evidence.
+
+Repair blockers and straightforward warnings with the smallest edit. Before `edit_office`, use `office_read` to get the exact target path, then call `edit_office` with `preview:false`. Its automatic first-page preview must not run ahead of structural validation or substitute for current review evidence. Consolidate all known defects into one edit batch where possible before requesting new render evidence. After each repair batch, call `office_review` with `action:"check_and_render"`, rerendering only affected slides at a new `artifact_revision`; never rerender an unchanged page/revision. Continue only while current evidence identifies a concrete blocker or a proportionate repair. Stop when only non-blocking warnings remain or another pass would not materially improve the user-facing deck, and disclose those warnings. If a blocker remains unresolved, do not publish the deck as complete; preserve and report the last structurally valid artifact when useful and label the remaining boundary. Existing-deck edit work may continue with another safe, evidence-based pass when it can resolve a remaining blocker without changing the authorized scope.
+
+Do not repair by hiding content, shrinking all text globally, flattening the page, removing source labels, or changing the locked narrative without evidence that the plan itself was wrong.
+
+## Delivery gate
+
+For a `REVIEW` route, the requested deliverable is the review report in the
+assistant message. Do not call `create_pptx`, `edit_office`, or
+`publish_outputs`, do not create a review copy, and leave the source byte-identical.
+Do not create or update a runtime execution plan for review-only work; deliver
+the evidence-based report directly after inspection so plan bookkeeping cannot
+suppress it.
+The PPTX publication rules below apply only to `CREATE` and `EDIT` routes.
+
+Publish only when:
+
+- OpenXML validation passes;
+- every required render was reviewed or unavailable checks are explicitly disclosed;
+- no blocker remains;
+- the final whole-deck review records concrete observations and any remaining non-blocking warnings;
+- the final path is the validated candidate, not an earlier draft or backup.
+
+Do not call `publish_outputs` until the last current-render review and its
+quality record are complete. If any edit or render-based review happens after
+publication, treat the published result as stale and publish the validated
+candidate again only after all gates pass.
+
+Call `publish_outputs` with only that final `.pptx`. The handoff names the path, slide count, edits or produced scope, plain-language content/design/flow result, checks actually run, repair passes, source limitations, unsupported PowerPoint features, and any target-viewer review still needed. Do not expose the internal route or depth codes in the handoff.
+
+The final handoff must make the review evidence auditable instead of saying
+only “checked” or “looks good”. Include three short labeled lines—`内容`, `设计`,
+and `连贯性` (or natural equivalents in the user's language)—plus the number of
+slides structurally checked and rendered. Under `设计`, name the autonomous or
+reference-derived direction, the weakest observed page, material repairs, and
+remaining warnings. Do not include numeric aesthetic scores. Under `连贯性`, describe whether repetition,
+variation, and density support the narrative without forcing a numeric family
+count or prescribed rhythm. Do not invent observations that were not recorded
+from current renders.
+
+Use this compact handoff shape so the evidence is understandable and cannot be
+lost during a long tool run (replace every bracket with observed evidence):
+
+```text
+内容：目标动作是 [企业购方在汇报后要做的决策]；[8] 页均使用结论式标题且每页一个主结论，例如 [P2 实际标题] / [P5 实际标题]；[页面覆盖与叙事路径]；[证据边界]；结构检查 [8/8] 页通过。
+设计：[8/8] 页已逐页渲染；视觉来源为 [自主设计 / 文字方向 / 参考图 / 参考 PPT]；视觉系统为 [具体艺术方向、主要颜色、字体层级、画布/背景和图片处理]；最弱页面为 [P# 与实际观察]；[已完成的定向修复]；[原生可编辑文本、图形、图表/表格的实际覆盖]；[剩余非阻塞提示或无]。
+连贯性：[重复和变化如何服务叙事]；[信息密度和章节节奏的实际观察]；[参考一致性或自主设计一致性]。
+```
+
+Do not replace concrete render observations with vague claims such as “整体良好”. Include the actual visual source, art direction, palette behavior, type hierarchy, background/canvas language, and image/chart treatment so the user can understand what visual system was delivered. Exact grid, margin, and palette values are useful when they materially explain the result, but their omission alone is not a publication blocker.
+
+For a generated product deck, the Content line must include the action
+objective and at least two actual conclusion-title examples from the current
+file. If the current titles are bare topic labels, repair them before handoff
+only when the user did not explicitly fix that visible wording. Never rewrite a
+contracted title merely to make it more assertion-like.
+After the three evidence lines, include a compact slide map for every slide in
+the form `P# — [actual takeaway] | [actual visual focus]`. This map is required
+for a generated deck so the story sequence and editable visual choices can be
+reviewed independently; do not substitute a topic-only agenda or a count of
+layout families.
+Then include one compact audit row for every generated slide, derived from the
+current render: `P# — Content PASS/WARNING/BLOCKER; Design
+PASS/WARNING/BLOCKER; Coherence PASS/WARNING/BLOCKER`. Every non-pass result
+must add the observed evidence in the same row. The takeaway/visual-focus map
+does not replace these per-slide three-dimensional records, and a positive
+summary does not override a page-level finding.
+Build this audit block before `publish_outputs`, count its rows, and verify that
+the count equals the generated slide count and that every page number appears
+exactly once. Missing, duplicate, or deck-level-only audit evidence blocks
+publication. After publishing, copy the already-counted block into the final
+handoff instead of reconstructing it from memory.
+For a generated deck grounded in supplied files or data, also include a compact
+`来源事实` ledger. Name every source file, reproduce every numeric sequence with
+its period or region, unit, and actual/target status, and list material
+non-numeric constraints or risks that the deck carries forward. This ledger
+must come from the current sources and deck; it is handoff evidence, not a
+license to add or reinterpret facts.
+The Design line should name the actual construction choices that matter to the current deck. Prefer concrete colors, type anchors, alignment logic, and crop/background treatment when they were recorded, but do not turn a fixed token checklist into a release gate for a reference-led or intentionally custom composition.

+
+# PPT Router
+
+Read this skill first and alone for every PptMaker request. Lock the route before reading `ppt-planner`, `ppt-craft`, `ppt-review`, or the shared `office-ppt` Skill.
+
+## User-facing progress
+
+The route and depth are private execution metadata. Keep them in working context only; never print the route contract, YAML fields, skill names, tool names, or labels such as `路线锁定`. Never show raw codes such as `CREATE / STANDARD` to the user.
+
+If a progress update is useful, write one short sentence in the current User UI language that describes the real presentation work. Prefer concrete, reassuring copy such as:
+
+- `正在梳理内容结构，确认每一页要表达的重点…`
+- `已确定内容结构：8 页，面向企业客户。接下来开始设计页面。`
+- `正在制作幻灯片，并统一版式、字体和配色…`
+- `正在逐页检查内容和版式，发现问题会直接修正…`
+- `PPT 已完成，正在整理交付文件…`
+
+Translate these examples naturally when the User UI language is not Chinese. Use actual task facts instead of repeating the example values. Do not narrate every internal step, repeat near-identical updates, or make the user decode implementation terminology.
+
+## Route
+
+Choose exactly one:
+
+- `CREATE`: the user needs a new editable PPTX from a topic, outline, documents, data, or mixed source material.
+- `EDIT`: the user supplied an existing PPTX and wants supported content or layout changes, cleanup, or a bounded redesign.
+- `REVIEW`: the user wants inspection, critique, risk findings, template-residue detection, or QA without an authorized file change.
+- `OUTLINE`: the requested deliverable stops at a brief, outline, storyboard, or slide plan rather than a PPTX.
+
+For `OUTLINE`, the requested storyboard is itself the plan. For `REVIEW`, the
+requested evidence-based review report is itself the result. Answer either one
+in the current turn and do not create a separate runtime execution plan; an
+unfinished runtime plan can suppress the useful storyboard or report and leave
+the user with only a completion status.
+
+Do not route a mixed Word/Excel/PDF package here merely because it contains one deck. Do not treat legacy `.ppt`, WPS `.dps`, Keynote `.key`, a browser slide site, or a PDF as an editable PPTX source. They may inform a new deck or a review, but direct mutation requires a converted `.pptx`.
+
+## Depth
+
+- `QUICK`: use when the user explicitly asks for a fast draft, the deck is small and low risk, or the content and visual direction are already complete. QUICK compresses planning; it does not skip the brief, evidence boundary, storyboard, design lock, validation, or render review.
+- `STANDARD`: use for source-heavy work, executive/board/customer/investor/sales/teaching/defense decks, more than six slides, ambiguous narrative, an existing-deck redesign, or any request where weak structure would be expensive.
+
+An explicit review gate is part of the lock. If the user did not request one, do not stop merely to ask approval for an internal outline or visual direction. Continue with recorded assumptions unless one missing decision would materially change the result.
+
+A named reference file plus an explicit role such as “style inspiration”,
+“strict template”, “edit this deck”, or “review only” is enough to proceed. Do
+not respond with a generic client/product/content questionnaire before
+inspecting that input. Missing factual copy may be represented by neutral
+headings, visible placeholders, or clearly labeled draft assumptions; it does
+not block reference inspection, visual planning, or safe template mapping.
+
+## Visual source
+
+Resolve the visual source without making reference material a prerequisite:
+
+- `autonomous`: no reference image, brand system, template, or visual direction was supplied. This is a complete first-class creation path, not a degraded fallback. Continue without asking the user to provide inspiration, and let `ppt-planner` derive an art direction from the audience, communication job, content, and evidence.
+- `text-direction`: the user described a mood, style, brand character, or visual preference without supplying a visual file.
+- `reference-image`: one or more supplied images, screenshots, or rendered pages influence the visual language. Do not assume the images may be reused as slide assets unless the user supplied them for that purpose.
+- `reference-deck`: a PPTX or rendered deck is inspiration or a template source for a new presentation. Distinguish style inspiration from authorized template reuse before construction.
+- `existing-deck`: the supplied PPTX is the artifact to edit or review.
+
+Infer the mode from the request and files. Ask only when confusing a style reference with an editable/template source would materially change the artifact. User instructions and authorized reference/brand material outrank autonomous defaults. A reference never authorizes copying third-party claims, logos, unique illustrations, or proprietary assets.
+
+For reference-led creation, the first concrete action is to inspect the named
+reference within its declared role. Continue from that evidence into planning
+and production without asking whether the user wants you to begin. If the
+current transport cannot execute file operations, provide the complete
+unexecuted inspection, visual-extraction, construction, and review sequence in
+plain presentation language in the same reply; do not expose private tool or
+skill names.
+

+description_en: After route lock, creates a shared canvas contract only for multi-region images, explicit reading order, exact layout, or region-bound references; skip simple single-region images.
+---
+
+# Image Canvas
+
+Read this private ImageStudio skill only after route lock when the result has multiple meaningful visual regions, an explicit reading order, exact layout constraints, or references bound to regions. Skip it for a simple single-region image. If art direction is also needed, read `image-craft` first. This adapts the Canvas-as-intermediate-representation method popularized by Omost into Orkas's provider-neutral manifest; it does not import an Omost model runtime.
+
+## Canvas contract
+
+Populate the canonical `image-manifest.json` template's `visual_plan` object when the image has more than one meaningful visual zone:
+
+- `global_description`: the complete visual thesis in one concrete sentence.
+- `reading_order`: every region id in intended eye-travel order.
+- `regions`: stable objects whose normalized coordinates are nested under `regions[].bounds` as `{x,y,width,height}`; never place `x`, `y`, `width`, or `height` directly on a region. Each region also has `background`, `midground`, or `foreground` depth; exactly one supported role (`hero`, `support`, `copy`, `decoration`, or `background`); a visible description; `detail_prompts` as a string array; and `reference_ids` as a string array. Use empty arrays when a region has no detail prompts or references.
+
+Use as few regions as possible. Regions describe visible image logic, not implementation components. Reserve meaningful negative space deliberately and prevent hero, copy, and support regions from competing for the same focal priority.
+
+For `COMPOSE` and `HYBRID`, map every region to at least one HTML/SVG element with `data-image-region="<id>"`. ImageStudio blocks snapshots when the plan and DOM diverge. For `GENERATE` and `EDIT`, compile the global description and region details into the provider prompt, preserving the same reading order and crop.
+
+## Reference contract
+
+Before declaring individual references, write `reference_intent:{mode:"reproduce|edit|guide",basis:"user|inferred",instructions:[],minimum_score}`. Explicit user constraints always win; only an unspecified reference defaults to guide with inferred basis. Then declare each project-local reference with a stable id, one role (`style`, `identity`, `composition`, `structure`, `content`, `mask`, or `edit_source`), influence strength from 0 to 1, required state, attributes to preserve, attributes that may change, and target region ids. Reproduce uses a floor of at least 85; edit uses at least 80 and a required edit source with explicit instructions and non-empty change boundaries.
+
+Treat role as a constraint, not a vague inspiration label. A style reference must not silently become an identity reference; a composition reference must not copy unrelated content. Required reference files participate in the project signature, so changing them invalidates previous review evidence.
+
+Keep every `may_change` list within the changes the user explicitly allowed. An axis that a reference does not control stays unbound; it does not become permitted to change. For example, when a composition reference may change only to fit an aspect ratio, list only the necessary crop, framing, or layout adaptation—not scene, subject, content, or background changes.
+
+For provider controls, use `generation_contract.controls` with an existing reference id, control type (`image_prompt`, `canny`, `depth`, `pose`, or `mask`), strength, and start/end window. This records IP-Adapter/ControlNet-style intent without coupling the project to one provider.

+description_en: After route lock, produces COMPOSE work or deterministic layout, diagram, overlay, crop, mask, and composite phases with local HTML/CSS/SVG and private updateable scripts.
+---
+
+# Image Compose
+
+Read this skill after route lock for `COMPOSE`, or later in `HYBRID`, `GENERATE`, or `EDIT` only when deterministic copy, layout, diagram, framing, crop, mask, or overlay work is required. Do not preload it during routing. Keep the artifact in one stable directory containing `image-manifest.json`, `index.html`, and local assets.
+
+## Safe project bootstrap
+
+Create or repair `image-manifest.json` and `index.html` with `write_file` / `edit_file`. Do not assemble either file through `bash`, PowerShell, shell redirection, or an inline script: quoting damage can leave a partially written project and shell safety checks can block recovery.
+
+This production skill is the earliest point at which a `COMPOSE` manifest may be created. Initialize it from the `Canonical image-manifest v1` block in `image-router`; that block is the single structural source, so do not redefine or reconstruct the manifest shape here. Replace every example value with the current brief and planning output. Keep its nesting and value types exactly: `brief.purpose` and every `art_direction` field are required by native inspection, and any region coordinates belong under `visual_plan.regions[].bounds`.
+
+For `HYBRID`, `GENERATE`, or `EDIT`, set the locked lowercase route and the approved nonzero generation budget, then add the route-specific reference and request fields required by `image-router` / `image-generate`. After the first write, read the manifest back once and repair it with `edit_file` if needed before calling `project.inspect`.
+
+## Authoring contract
+
+- Start from the canvas and art direction in the manifest. Make the first render meaningful without network access or user interaction.
+- Keep decorative rules, strokes, and signature geometry outside every required-text bounding box. After any headline revision, recheck the full phrase at thumbnail size and repair any line or shape that crosses, crowds, masks, or visually splits a glyph or line of copy.
+- Fit every multi-glyph required headline as a complete phrase before snapshot. Automatic wrapping must never leave a line with only one glyph: widen the text box, reduce the type size, or author an intentional balanced `<br>` before capture. Do not approve a source merely because the DOM contains the exact string; line-by-line rendered legibility is the gate.
+- For a multi-image set, reuse the first passing image's concrete CSS/SVG design decisions—palette variables, type roles, spacing/grid, radii, strokes, icon treatment, material effects, and signature device—in every later member. Change the content and the layout details needed by that content; do not redesign the visual system per image.
+- Use semantic HTML for text and SVG for geometry, diagrams, strokes, charts, patterns, and masks. Use CSS for layout, texture, lighting, and controlled effects.
+- Preserve every required-copy string exactly in visible DOM text. Keep important text out of raster assets.
+- Preserve natural English casing: use sentence case or natural title case for titles and sentence case for body, captions, labels, and CTAs. Keep all caps only when that exact casing is explicit in required user copy or an external brand/source, and then only for one short metadata label, acronym, or code. Never apply `text-transform: uppercase` through a broad selector or use multiple all-caps text roles; create hierarchy with family, width, weight, scale, color, or spacing.
+- Use only local relative assets inside the project directory. Do not use scripts, CDNs, remote fonts, remote images, iframes, embedded pages, autoplay media, or a local server.
+- In `HYBRID`, use the generated raster as one deliberate layer and let HTML/SVG own copy, logo placement, framing, and layout.
+- Map every `visual_plan.regions[].id` to an HTML/SVG element with `data-image-region`. Treat supplied reference images as local assets: they remain usable in HTML through `<img>`, CSS backgrounds, SVG `<image>`, masks, crops, and overlays without a generation call.
+- Declare the fixed canvas on the `index.html` root with `data-preview-layout="fixed-canvas"`, `data-preview-width="<canvas.width>"`, and `data-preview-height="<canvas.height>"`. The two dimensions must exactly match `image-manifest.json`; this is the shared HTML viewer contract, not ImageStudio-specific presentation logic.
+- Size for the declared canvas. Avoid hidden overflow, tiny copy, edge collisions, and low-contrast focal content.
+
+## Skill-owned zero-call helpers
+
+Do not add native `image_studio` operations for authoring libraries. Run these private skill scripts through the generic skill runner; they can ship independently from the application security kernel:
+
+```bash
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" image-compose structured_visual -- --project project/image --input chart.json --output assets/chart.svg
+"$ORKAS_NODE" "$ORKAS_PC_DIR/bin/run-skill.cjs" image-compose image_asset -- --project project/image --request asset-request.json
+```
+
+Use `structured_visual` for deterministic `diagram`, `bar`, `line`, and `donut` SVGs. Read [structured-visuals.md](references/structured-visuals.md) before writing its JSON input. The output is static local SVG with no script, CDN, browser library, or model call. Use it for Mermaid/ECharts-class needs when a structured chart or graph is enough; author custom SVG when the visual idea needs an irregular editorial composition.
+
+Use `image_asset` with a project-local request JSON:
+
+- `capabilities`: report Sharp, optional `rembg`, and optional host-configured Real-ESRGAN.
+- `process`: Sharp-backed orientation, resize, crop, extend, rotate, blur/sharpen, flatten/trim, format conversion, and compositing.
+- `remove_background`: use host-managed `rembg` only when capability evidence says available.
+- `upscale`: use host-managed `ORKAS_REALESRGAN_BIN` only when capability evidence says available. This is local enhancement and does not consume the paid image-generation budget.
+
+Never install packages, download weights, or start a service. Keep input, request, and output paths inside the project. Prefer a new output path; set `overwrite:true` only for an explicitly replaceable intermediate.
+
+HTML cannot semantically reinterpret a reference. It can faithfully place, crop, mask, recolor, annotate, and composite a supplied image. If the requested result needs a new viewpoint, changed identity, relighting, or content-aware reconstruction, lock `HYBRID` or `EDIT` instead.
+
+## No-runtime production contract
+
+If the required authoring, snapshot, or export tools are unavailable, do not claim a finished image. Return a compact production contract that is still executable later: canvas and export format, exact copy, layout and reading order, one distinctive signature device tied to the subject, local asset/reference roles, typography and palette, and the locked route. The signature device must name its geometry/material and placement; a list of ordinary subject objects is not enough. Include an explicit pre-export checklist for copy/date/time/place accuracy, contrast, safe margins, clipping/overflow, thumbnail legibility, output dimensions/color mode, and reference rights or provenance when relevant. Every item needs a concrete pass criterion, not only a pending label: exact copy match, all required bounds inside the declared safe area, readable required text at feed-thumbnail size, no clipping/overflow, sufficient text contrast, exact export dimensions/format/color mode, and recorded rights/provenance. Mark the unexecuted result pending.
+
+## Native workflow
+
+1. Call `image_studio` with `project.inspect` after the manifest and entry exist. Repair all structural blockers before creating visual evidence. A failed structural inspection carries no model image. The native tool is a stable capture/evidence/export security kernel, not an authoring library registry.
+2. Only after inspection passes, call `image_studio` with `project.snapshot` and an output path. The passing snapshot attaches the exact full-color candidate as model-visible evidence. Inspect that attachment directly; do not reopen the same path through generic `read_files`, which is not the design-evidence transport.
+3. Apply one coherent repair batch if required, then repeat inspect and snapshot. Do not make serial cosmetic tweaks without new evidence.
+4. Inspect the current evidence and submit a structured verdict with `project.submit_design_review`.
+5. Call `project.export` only after a passing review of the exact current signature.
+
+`project.export` is the delivery gate. A changed manifest, HTML file, or local resource invalidates the prior review and requires a new snapshot.
+
+The first `project.export` call must use an explicit workspace-relative `output_path` ending in `.png`. After success, answer with the image instead of handing a completed direct request back to Commander.
+
+In the final delivery, briefly name the concrete checks that passed, not only the overall review score: exact copy/content, hierarchy or thumbnail legibility, contrast, safe margins and clipping/overflow, and export dimensions/format. Put those facts before the first preview. Show only exported final deliverables unless the user asks for review evidence, and write nothing after the last preview; the host may add its own produced-file footer.
+
+On a recoverable inspection, snapshot, review, or export result, use
+`project.status.current_candidate` and `recovery_context` to resume from the
+current files. Repair structural or visual findings and continue the native
+chain without asking the user for a technical confirmation. If no automatic
+repair remains, show the current candidate image and findings before asking
+for the smallest real creative or delivery decision.

+}
+```
+
+Use `direction:"TB"` for top-to-bottom flow. The script derives stable DAG levels; set an integer `level` on a node only when the intended grouping is otherwise ambiguous. Keep node count below the cognitive limit of the final canvas, even though the schema accepts up to 40.

+    ]
+  }
+}
+```
+
+Change `kind` to `line` for ordered trends. Use honest scales and preserve the user's units in the surrounding HTML or subtitle.
+
+## Donut chart
+
+Use one series. Labels and values must have equal lengths and values must total more than zero.
+
+```json

+  }
+}
+```
+
+After rendering, place the SVG in `index.html` through a local `<img>` or inline it when custom annotations are needed. Map the containing element to the matching `visual_plan` region and continue through native inspect, snapshot, scored review, and export.

+description_en: After route lock, turns original, restyled, or underspecified image requests into specific anti-template art direction; skip for precise mechanical edits or already-defined visual systems.
+---
+
+# Image Craft
+
+Read this skill only after route lock when the task needs original art direction, restyling, or clarification of an underspecified look. Skip it for crop, resize, format conversion, background removal, deterministic placement, or a narrow edit whose visual system is already defined.
+
+## Art-direction pass
+
+Populate all of the following inside the canonical `image-manifest.json` template's `art_direction` object; never place them at the manifest top level:
+
+1. `subject_world`: the concrete subject, setting, era, material culture, and audience expectation.
+2. `one_job`: the single thing the image must communicate at thumbnail size.
+3. `visual_tradition`: a real visual tradition or production language, not only mood adjectives.
+4. `composition`: focal point, camera or viewing angle, scale relationships, negative space, and reading order.
+5. `signature_device`: one memorable subject-specific device that prevents a generic template result.
+6. `typography`: type role, casing, weight, width, tracking, and copy hierarchy when text is present. Default English titles to sentence case or natural title case and body/supporting copy to sentence case. Preserve all caps only when exact user-approved copy or an external brand/source requires it, and limit it to one short metadata label, acronym, or code. A generic tech, editorial, premium, or cinematic mood never authorizes all caps.
+7. `color_light_material`: palette roles, light direction/quality, surface character, and depth treatment.
+8. `must_avoid`: visual clichés, unwanted objects, misleading claims, garbled text, and style failures.
+
+Reject vague defaults such as “modern, premium, cinematic” unless each word is translated into visible choices. Prefer one strong thesis over a collage of styles.
+
+For a multi-image set, define this art direction once for the set instead of independently re-expanding the style for every member. Treat the first produced image as the style anchor; GENERATE and EDIT rely on the image service rather than ImageStudio post-generation review. Later images may change their subject-specific content and local composition, but must carry forward the anchor's palette roles, typography roles, spacing/grid rhythm, shape and icon language, material treatment, and signature device unless the user explicitly requests a variation.
+
+## Prompt compiler
+
+For generated assets, order the prompt as: subject and action; environment; composition and camera; lighting; palette and material; visual tradition; required continuity; technical crop/aspect constraints; negative constraints. Do not ask the model to render important long-form copy, logos, UI labels, or diagrams; reserve those for the deterministic HTML/SVG layer.
+
+Use a Fooocus-inspired expansion pass without importing its runtime: preserve the user's core request verbatim as the prompt thesis, then expand only visible decisions supported by the brief and `visual_plan`. Separate positive description from `generation_contract.negative_prompt`. Do not add random quality tags, conflicting styles, named-artist mimicry, or details that change the requested subject.
+
+For references, first obey explicit user requirements, then the manifest-level reproduce/edit/guide intent, and only then inferred defaults. Assign a role and strength, state what to preserve, what may change, and which region it controls. Pass the same contract to `generate_image.reference_bindings`. Never request a protected artist imitation; describe observable visual properties and broader traditions instead.

+description_zh: 仅在 ImageStudio 已取得当前 inspect 或 snapshot 视觉证据后读取，用于多模态审美复核并绑定精确证据签名；任务启动和路由阶段不要读取。
+description_en: Read only after current ImageStudio inspect or snapshot evidence exists; performs signature-bound multimodal review and must not be loaded at task start or during routing.
+---
+
+# Image Design Review
+
+Read this skill only after a passing COMPOSE or HYBRID `image_studio project.snapshot` returns `visual_evidence.attached:true`. Never load it at task start, during routing, or in the same parallel batch as `image-router`. Never use it for a GENERATE or EDIT raster, including strict reproduction, semantic editing, explicit visual-QA wording, or multi-image consistency; the configured image service owns those guarantees. Inspect the attached complete full-color composition, not a textual description of it, a media URL, or the generic `read_files` grayscale preview of the same path. Failed deterministic inspection intentionally returns no visual attachment and must be repaired before this review begins.
+
+## Review rubric
+
+Check, in order:
+
+1. Intent: the image communicates the manifest's `one_job` and honors required subject, copy, references, and exclusions. Supplementary creative copy is allowed unless strict fidelity was requested. For strict, exact-only, or no-added-copy requests, treat any visible text outside the user's supplied copy as a blocker.
+2. Canvas and references: first read `reference_intent.mode`. For reproduce, compare every preserved attribute; for edit, verify every instruction while checking that protected/unaffected regions remain stable; for guide, ensure references influence only their declared role. Every planned region must remain visible in the intended reading order and no unrequested reference drift may appear.
+   Review the exact candidate path returned by the generation/edit handoff. It must byte-for-byte match the planned `output_path`; a missing or retyped path is a blocker, not a candidate to guess.
+3. Composition: focal hierarchy, crop, scale, balance, negative space, edge tension, and thumbnail legibility. Read each required headline line by line. An automatic wrap that leaves a one-glyph orphan line is a `fix`; widen the text box, reduce the type size, or use an intentional balanced break before passing. A decorative rule, stroke, or signature device that crosses, crowds, masks, or visually splits required copy is a `fix` (or a `blocker` when the copy becomes unreadable), never a passing flourish.
+4. Craft: lighting logic, color relationships, depth, material behavior, typography, alignment, and purposeful detail. Verify that English titles use sentence case or natural title case and body/supporting copy uses sentence case unless exact required copy or an external brand/source explicitly preserves different casing.
+5. Generation defects: anatomy, duplicated or fused objects, malformed hands/faces, unreadable pseudo-text, inconsistent perspective, and reference drift.
+6. Specificity: the signature device is visible and the result does not collapse into a generic template or undirected model aesthetic.
+
+## Multi-image style consistency
+
+When the user requests multiple COMPOSE or HYBRID images as one set, use the first image that passes design review as the style anchor. For every later image, place a project-local copy of that anchor in `references` as a required reference with `role:"style"`; use `reference_intent.mode:"guide"`, recording `basis:"user"` only when the user explicitly requested the shared style and `basis:"inferred"` otherwise; preserve palette roles, typography roles, spacing/grid rhythm, shape/icon/stroke language, material or lighting treatment, and the signature device; allow only the content and local composition changes needed by that member; and set `reference_intent.minimum_score` to at least 85.
+
+Inspect each later candidate and the style anchor side by side. Use the existing `reference_fidelity` score as the style-consistency score for that comparison. Treat an undeclared change in the preserved style axes as a `fix`, while normal content differences are not drift. Before delivery, inspect all final images side by side once, repair and re-review any visual outlier, and only then report that the set is style-consistent. Separate high individual scores are not evidence of set-level consistency.
+
+Then decide what the user sees. Preview every exported image in its intended order so the set reads as a set; a representative image or a contact sheet is enough when the user asked for a summary or showing everything inline would be less useful. This shapes the reply, not the export: never withhold or delay a passing export because of how many images the message shows.
+
+Classify findings as:
+
+- `blocker`: wrong subject or promise, missing required copy, unreadable key content, serious artifact, unsafe/misleading content, or an output that cannot serve the requested use.
+- `fix`: useful output with a concrete hierarchy, crop, color, typography, continuity, or craft issue that should be repaired before delivery.
+- `polish`: optional improvement that does not prevent delivery.
+
+Classify forced English all caps as `fix` when a title, body line, caption, label, or CTA was converted without an explicit casing requirement, or when two or more English text roles use all caps. Restore natural casing and use family, width, weight, scale, color, or spacing for hierarchy. Permit only one short metadata label, acronym, or code when its exact casing comes from required user copy or an external brand/source. Do not pass while native inspection reports `A_ENGLISH_ALL_CAPS_OVERUSE`.
+
+## Submit the verdict
+
+Score the actually viewed evidence from 0 to 100 before choosing the verdict:
+
+- `intent_alignment`: the requested promise and `one_job` are immediately visible.
+- `composition`: hierarchy, crop, balance, eye travel, negative space, and thumbnail legibility.
+- `craft`: color, lighting, depth, material, typography, alignment, and detail coherence.
+- `text_legibility`: required copy is exact, readable, and not model-garbled.
+- `defect_freedom`: no material generation, anatomy, duplication, perspective, clipping, or rendering defect.
+- `specificity`: the result has its declared signature device and avoids generic template/model defaults.
+- `reference_fidelity`: required only when the manifest has references; score the declared reproduce/edit/guide intent, roles, preserved attributes, allowed changes, and edit instructions.
+
+These mandatory dimensions are the comparable baseline, not a closed list. Add an `additional_dimensions` entry for every material task-specific quality axis that the baseline does not already cover, whether it comes from the user's request, the manifest, the medium, the visual system, or a concrete risk visible in the evidence. Examples may include brand coherence, product recognizability, icon-language consistency, data-encoding clarity, or set-level continuity, but the reviewer may define any other applicable axis. Do not add synonyms of the mandatory dimensions or easy dimensions merely to pad the review. Each entry requires a stable lowercase `id`, a user-facing `label`, a concise `reason` why it applies, concrete visible `evidence`, and a 0-100 `score`. Omit the array or send `[]` only when no material uncovered axis exists. Additional scores never raise the mandatory overall, but every one must meet the native dimension floor for a passing verdict.
+
+Call `image_studio` with `project.submit_design_review`, the exact evidence path, `quality_scores` as one object containing every mandatory score named above, any applicable `additional_dimensions`, `passed`, `repair`, or `blocked`, a short review scope, and `findings` as a string array. Native policy calculates the mandatory overall. `passed` requires overall >= 80, every mandatory or additional scored dimension >= 70, `findings:[]`, and reference fidelity at or above `reference_intent.minimum_score` (reproduce >=85; edit >=80); put any optional polish note in the review scope instead of findings. `repair` or `blocked` requires concrete non-empty findings. Do not inflate scores to cross the gate. A review applies only to the returned evidence signature; any source change invalidates it.
+
+Prefer one coherent repair batch. After repair, rerun inspect or snapshot and review the new evidence. Do not approve based on the previous image or on intention alone.

+description_en: After route lock, handles synthesized or reconstructed pixels for GENERATE, semantic EDIT, or the raster phase of HYBRID; skip COMPOSE and deterministic transforms.
+---
+
+# Image Generate
+
+Read this skill only after route lock when the task needs synthesized or content-aware reconstructed pixels: `GENERATE`, semantic `EDIT`, or the raster phase of `HYBRID`. Do not load it for `COMPOSE`, deterministic transforms, or overlays. It governs direct `generate_image` calls and the stable host workflow kernel; engine-specific request formats and reusable graphs remain private skill resources rather than new application tools.
+
+This production skill is the earliest point at which a manifest for a direct `GENERATE` or `EDIT` task may be created. Initialize `image-manifest.json` from the `Canonical image-manifest v1` block in `image-router`; it is the single structural source. Replace the locked route and budget, then add the reference and generation fields below. Do not reconstruct the base schema from memory.
+
+## Generation rules
+
+- Respect `generation_budget.max_calls` within the current user turn. The host reapplies this limit independently for each new user turn while retaining older transactions only as audit history. `COMPOSE` has a budget of zero; `HYBRID`, `GENERATE`, and `EDIT` normally use one call. Set a two-call budget only when the user explicitly requests iterative refinement or authorizes another billable attempt. A review finding alone never authorizes that second call.
+- Generate at the final aspect ratio whenever the provider supports it. Do not rely on destructive cropping to fix a mismatched composition.
+- Use reference images only when they encode composition, identity, product fidelity, or edit continuity that the prompt cannot preserve reliably.
+- Mirror manifest references into `generate_image.reference_bindings` using the exact concatenated reference order. Include role, strength, preserve, may-change, and target region. Send `generation_contract.negative_prompt` separately.
+- Compile `reference_intent.mode` into the request: reproduction asks for the declared protected attributes to match; guide limits influence to declared roles; editing uses the required `edit_source` as the original. User-declared instructions and boundaries have priority over inferred defaults and provider convenience.
+- Treat every planned `output_path` as one stable artifact binding. Reuse that exact string byte-for-byte for the provider/workflow result, later `project.inspect`, optional review candidate, and export input; never retype, derive, or silently correct the path in a downstream handoff.
+- For edits, send the manifest instructions, protected regions, unchanged attributes, and allowed changes explicitly. Prefer a localized edit over regenerating the full scene, and never reinterpret an edit as a fresh variation.
+- For reproduction, do not silently change subject, crop, layout, identity, typography, palette, or other preserved axes merely because regeneration is easier. Choose the provider/control path that can honor the declared fidelity floor.
+- For hybrid work, generate only the difficult raster layer. Exclude final copy, logos, labels, diagrams, and UI text from the model request.
+- Save every generated output inside the image project and record its relative path in `image-manifest.json` before inspection.
+
+`generation_contract.controls` records provider-neutral IP-Adapter/ControlNet-style intent. Translate its reference, strength, and target region into the generic reference contract. A provider may additionally consume structured fields, but never claim that it applied a native control unless returned capability or provider evidence says so.
+
+## Provider availability and billing disclosure
+
+Before every direct `generate_image` call, call `image_studio generation.quote` with the same stable `image_request_id`, exact `size`, and combined local-plus-URL `reference_count` that will be dispatched.
+
+- Treat the returned quote as a local capability check. `external` means the configured BYO/local provider can handle the request and may bill through its own account; `unavailable` is a blocker.
+- The open build does not estimate provider prices or maintain an in-app credit balance. Never infer a price from model names, cache a local price table, or multiply a remembered per-image rate.
+- Stop when the quote reports an unavailable provider or `sufficient:false`. Do not spend a new request id, consume a manifest call slot, or silently switch to another billing path.
+- `generate_image` checks provider availability again immediately before it creates the durable generation transaction.
+- A completed stable request id is reused without a new quote or provider call only within the same user turn. A pending or failed id remains closed in that turn and cannot be bypassed. A later user turn receives a fresh call scope even when it resumes the same project; do not treat earlier-turn exhaustion as current-turn exhaustion.
+
+When returning a cost decision or execution handoff, keep the state machine
+machine-readable: state whether dispatch is allowed, whether external billing
+applies, project call slots consumed in the current turn, the exact next operation, and the
+`generation.quote` recheck. Do not replace these fields with a vague prose
+summary.
+
+`project.status` may include a next-call quote using provider-default size and manifest reference count. Use it for orientation only; `generation.quote` must carry the exact request immediately before a direct call.
+
+## External workflows
+
+Use an external workflow only when the user or host has already configured ComfyUI, InvokeAI, AUTOMATIC1111, or IOPaint and a reusable project-local request offers a concrete control or model advantage. First call `image_studio workflow.capabilities`; never infer availability from a file or a prior session. Read [external-workflows.md](references/external-workflows.md) for the project-local formats.
+
+- The endpoint and credential are host-managed. Never accept, construct, print, or persist them in agent output or project files.
+- Read the engine-specific reference before drafting its request and preserve
+  exact field names instead of paraphrasing the protocol. For IOPaint edits
+  that protect unaffected pixels, set `request.sd_keep_unmasked_area:true`.
+- Validate the drafted request against the selected engine schema before
+  handing it off. An IOPaint masked edit that protects unaffected pixels is
+  incomplete unless the nested `request` object contains the exact boolean
+  `"sd_keep_unmasked_area": true`; a prompt, `protected_content`, or review
+  instruction saying "preserve unmasked pixels" does not replace this field.
+- `workflow_path` must be a project-local engine request JSON. Prefer a user-exported, reviewed graph; do not invent custom server nodes or install missing nodes/models.
+- Call `workflow.run` with the configured engine, stable `image_request_id`, project-local output, and optional output node/index. It consumes the manifest's durable generation budget, scoped to the current user turn, exactly like `generate_image`.
+- A host-configured workflow does not use in-app billing. Its host/provider may still have separate billing; report that billing as external and not estimated.
+- Treat `pending_uncertain` as a dispatched call in the current turn. Do not retry it or create a replacement request id in that turn; inspect the host queue and report the pending state.
+- Capability evidence proves protocol reachability, not that a particular graph node or model exists. Report the executed engine and returned dispatch evidence without claiming broader native-control support.
+
+An execution handoff must retain concrete, executable fields: the exact
+`workflow.run` operation, engine, project-local `workflow_path`, stable
+`image_request_id`, output path, manifest `max_calls`, and output node/index
+when applicable. The next-evidence chain must name `project.inspect` and
+`project.export` exactly. Never add `project.submit_design_review` for the
+generated raster; natural-language approximations are not an executable handoff.
+
+For missing capabilities:
+
+- Prefer the private `image-compose image_asset` script with host-managed Real-ESRGAN for zero-paid-call upscaling; a reviewed ComfyUI graph is the fallback.
+- Use an IOPaint request or a reviewed ComfyUI graph for mask-preserving inpaint/object removal. Keep unaffected pixels protected.
+- Use SAM/SAM2 or GroundingDINO only through an already installed, user-reviewed host workflow that materializes a mask. These projects are capability sources, not bundled Orkas runtimes.
+- Use AUTOMATIC1111 for existing host installations and `txt2img`/`img2img` compatibility. Never put HTTP credentials or base URLs in its request file.
+
+## Review loop
+
+After either generation path, call `image_studio` with `project.inspect`, passing the raster path. Deterministic project/raster validation always runs and records signature-bound evidence. It verifies that the project-local output exists, decodes, and matches the current manifest/signature; it never attaches a GENERATE or EDIT raster to a visual adapter, never requests quality scores, and returns `project.export` as the next operation. This is also the rule for strict reproduction, semantic edits, explicit visual-QA wording, and multi-image consistency: encode those requirements in the provider request and reference bindings, then rely on the configured image service's result. Do not load `image-design-review` or submit a design review for the raster.
+
+Export the exact validated raster through `image_studio`. Never start another provider call based on an ImageStudio post-generation judgment. Spend a second generation only after an explicit user request or approval, and make it address the user's requested change rather than an internal variation search. A definite pre-dispatch failure is recorded but does not consume a generation call; a dispatched, terminal failure or `pending_uncertain` attempt still counts in the current turn. If the authorized repair budget is exhausted in that turn, use `project.status.current_candidate` and `recovery_context`: keep the best image visible, apply any useful deterministic zero-call repair, report the remaining finding, and end the turn. Never raise manifest `max_calls` or request a quota-increase form to bypass the same-turn limit. A later direct user message starts a fresh turn-scoped allowance automatically; never carry earlier-turn exhaustion forward or request extra authorization solely because that earlier turn used its calls. Ask the user only for a material intent/quality/reference/delivery tradeoff, using normal chat rather than a recovery form.

+# External image workflow formats
+
+All files below stay inside the image project. Endpoints and credentials are host-managed and never appear in these files.
+
+## ComfyUI
+
+Use API-format JSON exported by the user's working ComfyUI installation. Accepted forms are the raw prompt graph, `{ "workflow": { ... } }`, or `{ "prompt": { ... } }`. Optional top-level `output_node_id` and `output_index` select the output deterministically.
+
+Real-ESRGAN, SAM/SAM2, GroundingDINO, IP-Adapter, and ControlNet may be used only when the exported graph already contains working nodes and the host has the corresponding models. Never synthesize a graph around guessed custom-node class names. Orkas dispatches the graph but does not install or certify its nodes.
+
+## InvokeAI
+
+Use an exported graph, `{ "graph": { ... } }`, or the complete `{ "batch": { ... }, "prepend": false }` enqueue request. Optional top-level `output_node_id` and `output_index` choose a result.
+
+## AUTOMATIC1111
+
+Text-to-image request:
+
+```json
+{
+  "mode": "txt2img",
+  "request": {
+    "prompt": "compiled positive prompt",
+    "negative_prompt": "compiled negative prompt",
+    "width": 1024,
+    "height": 1024,
+    "steps": 28,
+    "seed": 42
+  },
+  "output_index": 0
+}
+```
+
+Image-to-image or inpaint request:
+
+```json
+{
+  "mode": "img2img",
+  "init_image_paths": ["references/source.png"],
+  "mask_path": "references/mask.png",
+  "request": {
+    "prompt": "localized edit prompt",
+    "negative_prompt": "unwanted changes",
+    "denoising_strength": 0.45,
+    "inpaint_full_res": true,
+    "inpainting_mask_invert": 0,
+    "steps": 28,
+    "seed": 42
+  },
+  "output_index": 0
+}
+```
+
+The kernel reads and embeds only project-local PNG, JPEG, or WebP references. Keep the source and mask dimensions equal. Set API defaults explicitly for reproducibility rather than relying on UI defaults.
+
+## IOPaint
+
+```json
+{
+  "image_path": "references/source.png",
+  "mask_path": "references/mask.png",
+  "request": {
+    "prompt": "remove the distracting sign and reconstruct the brick wall",
+    "negative_prompt": "new objects, changed person, text",
+    "hd_strategy": "Crop",
+    "sd_strength": 0.75,
+    "sd_steps": 32,
+    "sd_seed": 42,
+    "sd_keep_unmasked_area": true
+  }
+}
+```
+
+The mask uses white for the edited area. Use an empty prompt for a host erase model such as LaMa; use a concrete prompt only when replacement or semantic reconstruction is intended. The engine returns one image, so `output_index` is always zero.
+
+## Dispatch rules
+
+1. Call `workflow.capabilities` and select only an `executable:true` engine.
+2. Keep one stable `image_request_id` per generation intent.
+3. Call `workflow.run` once. `pending_uncertain` means the request may be running; never retry blindly.
+4. Inspect the returned raster, score current evidence, and repair only from concrete findings within the manifest budget.

+description_zh: ImageStudio 每次任务首先且单独读取的路由技能；按用户意图、画面类型和成本选择 COMPOSE、HYBRID、GENERATE 或 EDIT，再决定后续需要读取的技能。
+description_en: The first and only ImageStudio skill to read before route lock; selects COMPOSE, HYBRID, GENERATE, or EDIT from intent, visual requirements, and cost, then identifies the next skill to load.
+---
+
+# Image Router
+
+Read this skill first and alone for every image creation or revision request. Return a locked route before reading any other ImageStudio skill; do not batch this read with craft, canvas, production, or review skills.
+
+For a clear zero-input poster or social graphic, routine canvas and export choices are low-risk defaults: choose them without asking and state the chosen defaults in the delivery. Ask only when a missing choice changes subject, required copy, brand fidelity, reference intent, paid budget, or final format.
+
+Before routing any request with a supplied image, classify the user's relationship to that image. An explicit user requirement always wins. Only when the user did not specify the relationship may ImageStudio infer a default:
+
+- `reproduce`: make the result match the declared composition/content/style attributes of the reference.
+- `edit`: treat one required `edit_source` as the original and change only the requested attributes or regions.
+- `guide`: use only the declared roles as guidance while allowing the stated changes. This is the safe default for an otherwise unspecified reference.
+
+Record this as `reference_intent:{mode,basis:"user|inferred",instructions,minimum_score}`. Use `basis:"user"` when the mode or constraint comes from the user's words and `basis:"inferred"` only for a fallback. A requested source edit implies edit; an explicit match/recreate/restore request implies reproduce; an otherwise unspecified reference defaults to guide. If instructions combine editing with strong preservation, keep mode edit and place the user's exact preservation requirements in the protected boundary. The intent is about the requested outcome, never about which app or technique produced the reference.
+
+## Route selection
+
+- Choose `COMPOSE` when typography, diagrams, charts, abstract geometry, cards, covers, posters, social graphics, simple illustrations, or brand layouts can be expressed faithfully with HTML/CSS/SVG. This route uses zero image-generation calls.
+- Choose `HYBRID` when one photographic, painterly, character, or textured raster asset is needed but exact copy, layout, logo placement, or labels should remain deterministic in HTML/SVG. The normal budget is one generated raster asset per user turn.
+- Choose `GENERATE` when the desired output is primarily photographic, cinematic, painterly, character-led, or otherwise depends on synthesized pixels. The normal budget per user turn is one call. Allow a second billable call only when the user explicitly requests iterative refinement or authorizes another attempt; a visual finding by itself is not authorization.
+- Choose `EDIT` when the user supplied a raster image and requested a semantic pixel change that HTML overlays cannot accomplish. The manifest must use `reference_intent.mode:"edit"`, name a required `edit_source`, list the exact instructions, and preserve every unaffected region.
+- Distinguish `HYBRID` from `EDIT` by the final artifact contract, not merely by the presence of a supplied photo. A poster or layout that keeps a supplied product/subject image as an immutable foreground layer, generates a separate background asset, and places exact copy/logo deterministically is `HYBRID`. Use `EDIT` only when the final raster remains the supplied source canvas and pixels inside that source must be semantically reconstructed, such as replacing a portrait background in place.
+- A `reproduce` request does not force `EDIT`: choose COMPOSE, HYBRID, or GENERATE according to the visual material required to reproduce the declared attributes.
+
+Route using call count and capability, not a remembered provider price. Once a generated route and exact request exist, `image-generate` checks the configured BYO/local provider with `image_studio generation.quote`; the router must not hard-code or locally calculate prices. External providers and host workflows are reported as externally billed and not estimated in-app.
+
+## Lock output
+
+Lock the route in the routing handoff, but do not create or edit project files during routing. `image-manifest.json` is written only after the selected production skill (`image-compose` or `image-generate`) has been read and the routed planning skills have supplied their values. It uses numeric `schema_version:1`. For every reference, lock whether it controls style, identity, composition, structure, content, mask, or edit source; record what must remain and what may change. User-declared instructions, roles, regions, preserve, and may-change items override inferred defaults. Reproduction requires `minimum_score >= 85`. Editing requires `minimum_score >= 80`, at least one instruction, and non-empty non-overlapping preserve/may-change boundaries on the required edit source. Do not switch routes after authoring begins unless the user changes the deliverable or the current route is technically incapable of satisfying it.
+
+Supplementary creative copy is allowed when the user did not request strict fidelity; keep it editable and do not present it as user-supplied fact. When the user asks for strict, exact-only, or no-added-copy output, `brief.required_copy` is the complete visible-copy allowlist: do not add subtitles, quantities, credentials, promises, or CTAs.
+
+## Canonical image-manifest v1
+
+This is the single structural template for `image-manifest.json`. Production skills must copy its nesting and value types instead of reconstructing the schema from memory. Replace every example value with the current brief, route, and budget; the host applies `generation_budget.max_calls` independently to each user turn and keeps prior-turn transactions only for audit. Omit optional `visual_plan` only when `image-canvas` was not selected. Route-specific reference and generation fields extend this template without changing its existing nesting.

+
+## Progressive-disclosure handoff
+
+Return `route`, `reason`, `generation_budget`, and a phased `next_skills` list:
+
+- Add `image-craft` only for original creation, restyling, or an underspecified visual direction.
+- Add `image-canvas` only for multiple meaningful regions, explicit reading order, exact layout constraints, or region-bound references.
+- Add `image-compose` for `COMPOSE`, or later in another route only for a deterministic overlay, layout, diagram, crop, mask, or composite.
+- Add `image-generate` for `GENERATE`, semantic `EDIT`, or the synthesized raster phase of `HYBRID`.
+- Never add `image-design-review` to startup. Load it only after a current COMPOSE or HYBRID snapshot exists. GENERATE and EDIT never use ImageStudio visual review, including strict reproduction, semantic editing, and multi-image sets; the configured image service owns those guarantees.
+
+When more than one skill is required, `next_skills` expresses execution order, not a parallel preload request. Read each skill only when its phase begins.
+
+For `COMPOSE` and `HYBRID`, use private `image-compose` scripts for evolving authoring/asset capabilities and reserve native `image_studio` for inspect, capture, review, and export. For `GENERATE` and `EDIT`, use `generate_image` by default; choose a host-configured ComfyUI, InvokeAI, AUTOMATIC1111, or IOPaint workflow only after `workflow.capabilities` proves it executable and the project-local request provides a specific model/control advantage. Both paths use the same manifest budget and converge on deterministic `image_studio` inspection and export. Scored review remains part of COMPOSE/HYBRID snapshot delivery and never runs on a GENERATE/EDIT raster.
