+# Meldwork Development Rules
+
+## Working Style
+
+- Read the relevant code path before editing and state assumptions when behavior is unclear.
+- Keep changes small and directly tied to the request. Do not refactor adjacent code without a concrete need.
+- Before editing, name the files you will change and why. Use patch-based edits for reviewable changes.
+- Do not place screenshots, logs, generated packages, or temporary files in the repository root.
+
+## Product Boundaries
+
+- Meldwork is a local-first desktop application. Do not introduce a required server, container, or cluster dependency unless the task explicitly calls for it.
+- Keep Agent execution in the Electron main process. Renderer access must go through narrow, validated preload APIs.
+- Respect native Agent configuration and keep CLI integration provider-agnostic. Do not add gateway-specific adapters, provider overrides, or bundled patches for external tools such as Magpie.
+- Never expose executable paths, tokens, credentials, or unrestricted shell execution to renderer code.
+- Store secrets only through operating-system-backed secure storage. Do not add plaintext fallbacks.
+- Keep workspace write access opt-in. Conversations and groups stay local; do not add remote participants, cloud channels, or remote conversation storage.
+
+## Frontend And Desktop
+
+- User-visible text must support both Chinese and English through the existing i18n system.
+- Changes to chat behavior must be checked in Electron desktop mode.
+- New overlays must support Escape/back dismissal and prevent background scroll where applicable.
+- Preserve the existing visual language and responsive behavior; avoid unrelated redesigns.
+
+## Verification
+
+- Frontend tests: `npm --prefix frontend test`
+- Frontend builds: `npm --prefix frontend run build` and `npm --prefix frontend run build:desktop`
+- Desktop tests: `npm --prefix desktop test`
+- Desktop package validation: `npm --prefix desktop run pack`
+- Add or update focused tests when changing behavior, security boundaries, output structures, or conditional logic.
+- Report commands run and any verification that could not be completed.
+
+## Git Hygiene
+
+- Preserve unrelated user changes and never use destructive Git commands without explicit approval.
+- Commit messages should explain what changed, why it changed, and which checks were run.
+- Do not add generated dependencies, build output, credentials, or release artifacts to version control.

CHANGELOG.md

@@ -0,0 +1,207 @@
+# Changelog
+
+## 1.0.7 - 2026-10-27 (Meldwork-V1.0.7 prerelease)
+
+- Preserve streamed discussion replies across cancellation and reload; scope ACP notifications to the active session.
+- Support Hermes native stream JSON and avoid MiMo interactive plan prompts in headless runs.
+- Add Zcode with its official logo before Pi Agent, native default configuration, and explicit missing-key errors.
+- Let WorkBuddy use an explicitly selected model from its desktop configuration, without exposing credentials to the renderer.
+- Keep Chinese slash-separated text intact while retaining credential and local-path redaction.
+- Unify application, artifact, README, and website versions at 1.0.7.
+- License Meldwork's original source, documentation, and website under Apache-2.0: commercial use is permitted without separate authorization or license fees. Third-party notices remain applicable. Older entries below describe their historical release terms.
+- Native acceptance includes a real WorkBuddy response; six-Agent unlimited discussion cancellation and reload were checked with simulated adapters. Zcode's default provider still needs a valid API key; the observed OpenCode router's invalid `tool_calls` finish reason remains an upstream issue.
+- Apple silicon DMG and ZIP remain ad-hoc signed and unnotarized.
+
+## 0.1.6 - 2026-10-17 (Meldwork-V1.0.6 prerelease)
+
+### Agent Reliability
+
+- Tier authentication failures instead of treating any authentication-looking diagnostic as a sign-in problem, and retry transient provider errors.
+- Keep long-lived ACP Agents (Hermes, Kimi, MiMo, OpenCode) usable across stops, restarts, and hangs, including when a group alternates between read-only and write turns.
+- Stop the watchdog from killing Agents that are still thinking or building, and keep an ACP turn alive through traffic this client does not recognise.
+- Keep an Agent available through an inconclusive readiness probe and preserve its shell environment.
+- Let MiMo and OpenCode turns that call tools finish instead of returning a partial answer, and report a CLI's own error instead of EPIPE.
+- Launch WorkBuddy's app-bundled CLI again (it now ships only the lite bundle) and stop skipping every WorkBuddy permission check in write mode.
+- Refuse unsafe ACP permission requests during read-only turns.
+- Give direct chats the current request and the delivery contract again after a native session is rebuilt.
+- Compare installed Agent CLI versions as releases, so a newer installed CLI is not offered a downgrade.
+- Write workspace state compactly and durably, and record unhandled main-process faults in the diagnostics log.
+- Internal: split the auto-runner and the Agent invocation into modules grouped by purpose.
+
+### Group Conversations
+
+- Show group replies in the order Agents were dispatched.
+- Keep natural discussions going instead of ending on one slip, ask Agents to engage with each other, and let peers see workspace file paths.
+- Keep group members after an Agent failure, so one proxy 403 or an expired sign-in no longer removes an Agent from later turns, and recover groups that were emptied.
+- A member that is not ready no longer blocks a message to the whole group; skipped members are named.
+- Deliver attachments and knowledge bases to group Agents, and send Hermes image attachments over ACP.
+- Conversations no longer wait for each other, even in the same folder; writers inside one conversation still take turns.
+- Import only files an Agent wrote, including paths with spaces.
+- Explain run failures in Chinese and English instead of showing raw codes.
+
+### Interface
+
+- Start without waiting for Agent detection: the sidebar, home page, and composer show that detection is running.
+- Mark conversations that wait for your decision in the sidebar and list them on the home page; mark group runs that finished while you were in another conversation.
+- Add a General settings tab with language and a System, Light, or Dark appearance; System follows the operating system until you choose.
+- Explain on each Agent card why an installed Agent is unavailable: its installed version, the verified range, and the failed check.
+- Use a shared type scale and semantic status colors, keep secondary text within contrast guidelines, and keep long notices on screen long enough to read.
+- Keep unsent text per conversation, add Skip and arrow-key navigation to first-run onboarding, ask before deleting a cloud server connection, and show Gemini CLI's own logo.
+
+### Verification And Distribution
+
+- Frontend 357/357, desktop 1603/1603, and deterministic evaluation 6 cases / 18 results passed on a clean checkout.
+- DMG and ZIP are ad-hoc signed, without Apple Developer ID signing or notarization. No installed user application is replaced automatically.
+- Live coverage is limited to observed CLI versions and configurations; this release did not repeat the live Agent acceptance run.
+
+## 0.1.5 - 2026-09-09 (Meldwork-V1.0.5 prerelease)
+
+### Local Agent Reliability
+
+- Accept validated OpenClaw gateway configuration migrations without disabling path, permission, or credential isolation checks.
+- Keep installed Agents visible when credential or capability checks fail; isolate failed probes and refresh the catalog after current readiness settles.
+- Refresh native shell settings before manual detection and preserve supported proxy, CA, cloud Provider, and model-region settings without silently replacing a selected Provider.
+
+### Group Conversations
+
+- Route peer requests through explicit Agent decisions instead of interpreting prose mentions or media keywords as commands.
+- Persist AI task completion separately from individual invocation success and human adoption; support single-Agent automatic work and exact visible answers.
+- Resume human clarification gates after restart, reject conflicting responses, and prevent repeated responses from replaying calls.
+- Serialize workspace writers, recover interrupted writes through bound approvals, retain partial results, and send acknowledged session context incrementally.
+- Preserve completed and stopped task states after restart and show healthy contributions alongside failed participants.
+
+### Verification And Distribution
+
+- Frontend 343/343, desktop 1562/1562, and deterministic evaluation 6 cases / 18 results passed.
+- Web and desktop builds, packaging, real packaged Codex/OpenClaw group execution, cancellation, and restart acceptance passed on Apple silicon macOS.
+- DMG and ZIP are ad-hoc signed, without Apple Developer ID signing or notarization. No installed user application is replaced automatically.
+- Live coverage is limited to observed CLI versions and configurations; cloud credential forwarding is not cloud-account certification. Full evidence: `docs/releases/Meldwork-V1.0.5.md`.
+
+## 0.1.4 - 2026-09-01 (Meldwork-V1.0.4 prerelease)
+
+### Natural Group Discussions
+
+- Sequential discussion mode now runs one Agent at a time in the configured CLI order and records every round visibly.
+- Auto Discussion starts with concurrent proposals, then lets Agent responses route the next turn through exact final-line `@Agent` mentions. One mention runs one Agent; multiple mentions run concurrently.
+- Natural discussion prompts allow Agents to exchange views before work and review instead of forcing every turn into a review-only role.
+
+### Session And Recovery
+
+- Reuses one native Agent session per Agent task across discussion rounds and restarts.
+- Persists round messages and checkpoints before and after Agent execution so completed turns are recovered without duplicate reruns.
+- Rejects stale operation and snapshot bindings before late results can be committed.
+
+### Verification And Distribution
+
+- Focused natural discussion coverage: 17/17 tests passed.
+- Desktop syntax checks and `git diff --check` passed.
+- The Apple silicon DMG and ZIP are ad-hoc signed and not notarized. Live CLI behavior still depends on each installed Agent's version, authentication, Provider, and capabilities.
+
+## 0.1.3 - 2026-08-18 (Meldwork-V1.0.3 prerelease)
+
+### Concurrent Conversations
+
+- Concurrent Responses now treats an empty explicit selection as the whole group, so users can send one message to every group Agent without adding `@` mentions first.
+- Keeps every group member in the frozen batch. Agents beyond the available Scheduler capacity remain visibly queued instead of being removed from the request.
+- Preserves valid visible proposals when a CLI omits or malforms its proposal receipt, while later Auto Discussion phases retain their strict structured-receipt boundary.
+
+### Conversation Experience
+
+- Refines user-message metadata, Agent logos, inline Agent/Skill/knowledge mentions, Markdown rendering, mention-menu tracking, and narrow-layout wrapping.
+- Returns newly sent conversations to the active Agent loading state and keeps the animated return-to-bottom control for readers who have scrolled up.
+- Removes the special No round limit composer background, border, shadow, and container breathing effect. The infinity status cue and real collaboration phase feedback remain available.
+
+### Stop Durability
+
+- Persists completed and streamed concurrent Agent replies when the user stops a batch instead of removing already visible work.
+- Records stopped Agent attempts as interrupted, rejects late post-stop results, and resumes the stable batch commit idempotently after restart.
+
+### Packaging And Verification
+
+- Sets the frontend and desktop package version to `0.1.3` and publishes Apple silicon DMG and ZIP prerelease artifacts with a matching SHA-256 manifest.
+- Frontend tests: 306/306 passed. Desktop tests: 1338/1338 passed.
+- Web and Electron renderer builds, Electron `pack`, packaged acceptance, and `git diff --check` passed before release packaging.
+- The prerelease remains ad-hoc signed, without Apple Developer ID signing or notarization, and may require Open Anyway on first launch.
+
+## 0.1.2 - 2026-08-18 (Meldwork-V1.0.2 prerelease)
+
+### Collaboration Harness V4
+
+- Replaced the legacy group reply label with Concurrent Responses while preserving the existing `manual` persistence and IPC value.
+- Freezes one shared task snapshot before Scheduler leases, keeps every selected Agent in the batch, isolates same-batch replies, and commits completed replies in stable member order.
+- Starts Auto Discussion with independent parallel proposals instead of assigning the first Agent as the primary author and every later Agent as a review-only participant.
+- Lets the selected Agents challenge proposals and negotiate one responsibility graph. Harness validates unanimous agreement on the normalized plan, dependencies, permissions, and participant coverage instead of privately assigning the work.
+- Runs distinct agreed work packages, selects one synthesis writer, and binds independent verification to the current candidate Artifact. Contradictions remain tracked issues until resolved.
+- Adds strict structured collaboration receipts, bounded Artifact/Evidence references, compact delivery watermarks, phase-and-slot operation IDs, serialized Human Gates, and idempotent crash recovery.
+- Preserves V1 manual, V2 Auto Discussion, and V3 Task Graph records on their legacy parsers and executors.
+
+### Agent Runtime
+
+- Normalizes supported CLI output into streaming answer deltas, plans, status, tool lifecycle events, warnings, and terminal results without exposing raw commands, local paths, secrets, or chain-of-thought.
+- Improves Hermes streaming and tool-event capture while preserving its read-only SQLite final-result watermark and sanitized stdout fallback.
+- Improves OpenClaw stream and tool-event normalization in the Connector protocol, keeps its managed runtime state, Provider secret handling, and permission policy isolated, and closes disposable ACP sessions plus the authenticated loopback Gateway and in-flight health probes during shutdown.
+- Strips collaboration control blocks from user-visible messages, live deltas, durable traces, and later Agent context; invalid or missing required receipts fail the current phase.
+
+### Interface
+
+- Shows real collaboration phases for parallel divergence, cross-Agent challenge and negotiation, responsibility-based work, convergence, and independent verification.
+- Adds group-scoped unlimited-mode confirmation and state-driven motion with keyboard, Escape, `aria-live`, narrow-layout, and reduced-motion support.
+- Adds an animated return-to-bottom control to group and direct conversation timelines.
+- Keeps Agent message copy actions in the metadata row, aligns version switching, regenerate, and delete controls in the compact footer row, and hardens long-name, timestamp, and narrow-screen layout behavior.
+- Keeps legacy round-zero trace labels neutral instead of relabeling historical responses as concurrent work.
+
+### Durability And Safety
+
+- Records V4 phases, batches, slots, attempts, frozen snapshots, dynamic roles, result references, delivery watermarks, commit state, and typed Gate state in the Run Ledger.
+- Binds pending V4 Human Gates and continuations to the exact leased Agent attempt, allows safe read-only recovery, requires a Human Gate before retrying an ambiguous writable slot, rejects late results after stop, and resumes batch commits idempotently.
+- Rejects terminal Agent results and V4 phase advancement while an exact permission Gate is unresolved, rejects duplicate active ACP permission request IDs, and distinguishes known checkpoint failure from unknown post-write outcomes so live recovery state cannot regress behind the durable Ledger.
+- Keeps workspace writes opt-in. Concurrent replies, proposals, challenges, negotiated work, and verification remain read-only; only the synthesis writer receives write authority when enabled.
+- Restricts renderer snapshots to validated phase, participant, role, progress, and Gate fields. Prompts, executable paths, native Session references, internal snapshot IDs, and unrestricted tool payloads remain main-process only.
+
+### Packaging And Distribution
+
+- Sets the desktop package version to `0.1.2` with permanent Bundle ID `com.rydersun.meldwork`.
+- Produces Apple silicon DMG and ZIP prerelease artifacts using ad-hoc signing. This is not Apple Developer ID signing or notarization and may require Open Anyway on first launch.
+- Keeps `dist:public` as the fail-closed future formal-distribution path requiring a Developer ID identity, Hardened Runtime, complete Apple notarization credentials, and post-sign validation.
+- This historical release used the Meldwork Non-Commercial Source License and required prior written permission for commercial use. Current releases use Apache-2.0 as stated above.
+
+### Verification
+
+- Frontend tests: 302/302 passed. Desktop tests: 1335/1335 passed.
+- Deterministic Eval Harness: 6 cases and 18 results passed.
+- Web and Electron renderer builds, Electron `pack`, and `git diff --check` passed on the final source tree.
+- Packaged Manual V4 completed with Codex, Claude, and Hermes evidence; packaged Auto Discussion V4 completed with Codex and Claude evidence; stopped runs remained stopped.
+- Hermes live streaming and tool lifecycle acceptance passed. The latest OpenClaw live run failed closed with `LOCAL_AGENT_PROCESS_FAILED`; protocol fixtures and managed-runtime tests pass, but OpenClaw live streaming/tool acceptance is not claimed.
+- The final 360 x 800 packaged UI acceptance passed for group and direct return-to-latest behavior, Trace layout, message actions, and stop durability. A separate Codex direct run exceeded the 300-second observation window before completing late, so it is retained as a live timing limitation rather than counted as a UI failure.
+- Release DMG and ZIP digests are published in `SHA256SUMS.txt` and verified against the uploaded assets.
+- The prerelease remains ad-hoc signed, without Apple Developer ID signing or notarization; `spctl` rejection remains expected.
+
+## 0.1.0 Private Preview 1 - 2026-08-03
+
+This private preview packages the initial Meldwork MVP for internal evaluation on Apple silicon Macs.
+
+### Highlights
+
+- Local-first direct conversations and persistent multi-Agent working groups.
+- Automatic multi-round discussions with explicit Agent targeting and bounded execution.
+- Durable, sanitized run traces for reviewing Agent activity without exposing credentials, executable paths, or private reasoning.
+- Independent Provider profiles, native Agent session continuity, Skills, knowledge-source references, images, and controlled workspace access.
+- Support for Codex, Hermes, OpenClaw, WorkBuddy, Kimi Code, MiMo Code, Claude Code, Gemini CLI, OpenCode, Qwen Code, OpenCodeReview, and Custom Agents.
+- Major frontend and Electron modularization while preserving the existing UI and public desktop bridge contracts.
+
+### Distribution
+
+- macOS Apple silicon: DMG and ZIP artifacts.
+- Private preview only. The application was ad-hoc signed and not notarized with an Apple Developer ID.
+- Windows and Intel Mac release artifacts were not included.
+
+### License
+
+Meldwork was source-available under PolyForm Noncommercial 1.0.0 for this historical preview. Commercial use required a separate written agreement.
+
+### Verification
+
+- Frontend tests: 217 passed.
+- Desktop tests: 470 passed.
+- Web and Electron frontend builds passed.
+- Electron packaging, ASAR inspection, and deep signature verification passed.

-## 产品文案定位
+# Meldwork — Let Agents collaborate to move tasks forward
 
-核心表达：**提出目标，让 Agent 们协作完成。** Meldwork 是本地优先的多 Agent 协作工作空间，让选定的 Agent 共享上下文、讨论方案、在授权范围内执行并相互检查，减少用户转述和协调下一步的工作。用户设定目标和权限，在需要补充信息、授权或关键决策时介入。
+**Set the goal. Let Agents work together. Meldwork brings your existing Agents into one working group to share context, discuss approaches, carry out work, and check each other's results — with less relaying, prompting, and stitching outputs together.**
 
-过程记录用于回看进度与产物，不宣传为完整的事实核验或证据溯源能力，也不承诺所有任务都能无人干预完成。首页正文、搜索摘要、社交分享摘要和 JSON-LD 使用同一定位。
+Meldwork is a local-first multi-Agent collaboration workspace for the Agent tools you already use on your Mac. Once you choose the participants, goal, context, and permissions, Agents in Auto Discussion can build on each other's work, request contributions or reviews, and advance the task within the authorized scope. Direct conversations and independent concurrent responses also support research, analysis, writing, planning, review, and implementation.
 
-## 打开方式
+You do not need to direct every round, but you still set the goal, grant permissions, and make key decisions. Missing information, permission requests, or tradeoffs may require your input. Workspace writes are opt-in; collaboration history, run state, and deliverables stay local so you can revisit the work and continue it.

+## What Meldwork is for
 
-## 品牌物料复用（assets/）
+Meldwork is useful when several Agents need to advance the same task and you want to spend less time passing context and coordinating next steps. Typical work includes:
 
-| 物料 | 来源 | 用途 |
+- research and information synthesis across local Agent tools and selected knowledge sources;
+- product, market, operational, and technical analysis;
+- writing, planning, review, and structured document work;
+- multimodal work with local documents, images, audio, video, PDFs, and code or configuration files;
+- implementation in an authorized workspace, with other Agents checking the deliverables and requesting revisions.
+
+## How a task moves through Meldwork
+
+1. **Select** the Agents that will work on the task together.
+2. **Scope** the goal, working directory, context, attachments, Skills, knowledge sources, and permissions.
+3. **Collaborate** in Auto Discussion: let Agents discuss approaches, carry out authorized work, and check results. Direct conversations and Concurrent Responses are also available.
+4. **Decide** when the work needs information, permission, or a tradeoff resolved.
+5. **Check the result** and request changes when more work is needed.

-## 设计决策
+Participants are selected by the user. Automatic selection from a larger roster is outside the current preview.
 
-- 配色取自产品暗色主题 token（`#121516` 底、`#93a0a5` 弱化文字）与 logo 珊瑚色 `#EF5A45`；导航激活的三点指示器刻意使用珊瑚色，呼应 Trace mark 的「人类采用点」。
-- 中英文标题采用本地 Fusion Pixel 字体，附带 OFL 许可证。
-- 统计条展示：13 个已支持 CLI、3 种协作模式、本地优先工作空间、1 个共享任务；Agent 模型调用仍可能访问各自配置的服务商。
-- 动效遵循 `prefers-reduced-motion` 降级；弹窗/移动菜单支持 Escape 与遮罩关闭并锁定背景滚动。
+## Revisit the process and continue the work
 
-## 语言
+Meldwork keeps task context, Agent replies, run state, and deliverables locally so you can see how work progressed, where it stalled, and what needs attention next. The Run Ledger preserves phase, participant, attempt, artifact, recovery, and Human Gate state. Diagnostic tool output and sensitive runtime details stay behind the Electron main-process boundary.
 
-右上角可切换中文 / EN，默认跟随浏览器语言，选择保存在 `meldwork-landing-locale`。正文与富文本翻译使用 `index.html` 的 `data-zh` 属性，`i18n.js` 统一更新语言、辅助标签、页面标题、分享摘要和中文 FAQ 结构化数据。即使本地存储不可用，也可在当前页面切换。官网不依赖 Vue 或额外构建步骤。
+These records help you inspect collaboration; they do not establish that every claim has been fact-checked. Peer review does not guarantee correctness, and important deliverables still need acceptance checks appropriate to their use.
 
-中英文标题与状态标签使用本地 Fusion Pixel 12px 等比例像素字体；正文使用 Inter 与系统中文无衬线字体。字体版本为 2026.10.16，来源为 [Fusion Pixel](https://github.com/TakWolf/fusion-pixel-font/releases/tag/2026.10.16)，字体及上游 OFL 声明保留在 `assets/fonts/fusion-pixel/`。

-官网强调色对齐产品：暗色 `#d98568`、浅色 `#d45f52`。透明色从同一组 RGB 变量派生，降低发光与背景视频饱和度；现有品牌标志不改色。
+Approved Agent Connectors and custom executable Agents use the desktop connector paths. The [desktop guide](desktop/README.md) contains the current adapter, installation, provider, and capability matrix.
 
-案例卡片通过背景明度和阴影区分当前贡献，不使用左侧描边。Agent Logo 采用白色底座，便于识别深色或透明图标。
+## Context and local boundaries
 
-## 全页字符余烬背景
+Meldwork runs as a local Electron application. Conversations, group configuration, run records, and app-owned attachments stay in the local user data directory. The renderer receives only validated snapshots through a narrow preload API; executable paths, credentials, native session references, Skill paths, and unrestricted shell access remain in the main process.
 
-`glyph-embers.js` 是原生 Canvas 实现，视觉方向参考 [React Bits Pro Glyph Ember](https://pro.reactbits.dev/docs/components/glyph-ember) 的公开描述：字符火焰、亮色底床与上升余烬。当前官网没有 React/shadcn 环境，且未配置 `REACTBITS_LICENSE_KEY`，因此没有安装 Pro 注册表组件，也没有复制其付费源码或新增 `components.json`。
+Selected Agents may send prompts, attachments, or Skills to the model provider configured in their own CLI. Knowledge access is explicit and bounded: the current implementation supports local Obsidian retrieval and CLI-owned Feishu or DingTalk access modes. Local-first describes where Meldwork stores and coordinates work; it does not promise that an Agent's model provider is offline.
 
-背景固定覆盖整个视口。多层连续噪声向上平流并扭曲火舌，混合字母与符号按热度映射为字符密度；底床由暖橙过渡至象牙白，独立的模糊辉光层与漂浮火星提供层次。卡片保持实色以保护阅读，首页原视频降低为次要背景。绘制上限为 20fps、280 列、110 行、1.5 倍像素比；页面隐藏时取消动画帧，减少动态效果模式仅绘制静态版本。背景不接收鼠标事件，并从辅助技术中隐藏。

The release also includes a ZIP archive and SHA-256 manifest. Install at least one supported local Agent CLI before opening the app.
 
-先安装现有前端开发依赖，再运行专项测试：
+The preview artifacts are ad-hoc signed and not notarized with an Apple Developer ID. macOS may require **Open Anyway** under **System Settings → Privacy & Security** on first launch.
+
+## Run from source
+
+Prerequisites: Node.js `22.12+` and npm.
 
 ```bash
-node --test meldwork-landing/test/landing.test.cjs
+npm --prefix frontend ci
+npm --prefix desktop ci
+npm --prefix desktop run dev
 ```
 
-该命令从仓库根目录执行，使用现有前端依赖中的 JSDOM，覆盖双语、语言记忆、完整文案、播放节奏、键盘控制与减少动态效果。视觉检查使用本地 HTTP 服务，同时检查中英文、明暗主题与窄屏。更新样式或脚本时同步刷新 `index.html` 中的资源版本参数。

-官网原创代码及文档采用 Apache-2.0，允许商用；第三方字体和 Agent 标志保留各自条款。见 LICENSE、NOTICE 和 COMMERCIAL_USE.md。
+Auto Discussion can complete native Agent turns on explicit completion and requires each participant to approve the same delivery version. A real six-Agent unlimited discussion completed in nine rounds with matching delivery hashes. This preview also improves Agent authentication status, handles CLI authentication errors reported on stderr, and bundles knowledge-base logos.
+
+Agent installation does not guarantee a working model connection: OpenClaw's isolated runtime may not support the native environment configuration, WorkBuddy's CLI may require its own login, and Zcode needs valid native provider credentials. Desktop and frontend regression checks passed 1,700 and 379 tests respectively.
+
+## V1.0.8
+
+V1.0.8 keeps Kimi read-only queries in manual approval mode instead of forcing a planning cycle, preserves MiMo's final text chunks, forwards supported native CLI configuration, and retains the selected Auto Discussion mode after sending. Repetitive native output is cancelled with partial replies preserved. Zcode remains before Pi Agent with its official logo and native default configuration; WorkBuddy can reuse a configured desktop model selected in Meldwork.
+
+Real CLI acceptance covered all 13 installed Agents. A five-Agent unlimited discussion completed all 14 native calls through an isolated Magpie hotfix. The installed Magpie version can rewrite `stop` into `tool_calls` when `tool_calls` is null, causing OpenCode, MiMo, and Hermes to continue indefinitely; this Meldwork release does not install or restart Magpie. OpenClaw, Zcode, Gemini, Qwen, and OpenCodeReview also had native configuration or authentication failures in this audit. Detecting an installed CLI does not certify a working model connection. Regression validation includes 1,655 desktop tests, 370 frontend tests, web and desktop builds, and package validation. Unlimited discussion retains stalled-process detection and write permissions remain opt-in.
+
+Electron acceptance with the same isolated gateway also completed a separate five-Agent unlimited discussion: 19 native calls, no failed attempts or retries, about 12 minutes. Auto Discussion and No round limit remained selected after sending, completion, and leaving and reopening the group. This verifies the workflow, not a response-time guarantee or a repair to the user's installed gateway.

+# Meldwork：让 Agent 自主协作推进任务
+
+**提出目标，让 Agent 们协作完成。Meldwork 把你已有的 Agent 组织成一个工作小组，共享上下文、讨论方案、协作执行并相互检查，减少你在它们之间转述、催办和整合结果的工作。**
+
+Meldwork 是一个本地优先的多 Agent 协作工作空间，用来连接你已经在电脑上使用的 Agent 工具。你选定参与者、目标、上下文和权限后，自动讨论中的 Agent 可以接续彼此的工作，请求同伴补充或检查，并在授权范围内推进任务。它也支持单个 Agent 的直接会话和多个 Agent 的独立并发回复，覆盖研究、分析、写作、规划、评审和实施。
+
+你无需安排每一轮发言，但仍负责目标、权限和关键决策。遇到信息缺失、权限请求或需要取舍的问题时，任务可能等待你处理。工作区写入需要明确授权；协作过程、运行状态和产物保存在本地，方便回看和继续工作。
+
+<p align="center">

+  · <a href="architecture.md">架构</a>
+  · <a href="LICENSE">许可证</a>
+</p>
+
+## Meldwork 适合什么工作
+
+当一个任务需要多个 Agent 共同推进，而你不想反复传递上下文、协调下一步时，Meldwork 更适合：
+
+- 研究与信息综合：结合本地 Agent 工具和明确选择的知识源；
+- 产品、市场、运营和技术分析；
+- 写作、规划、评审和结构化文档工作；
+- 处理本地文档、图片、音频、视频、PDF、代码和配置文件的多模态工作；
+- 在授权工作目录内执行、由其他 Agent 检查成果并继续修改的实施工作。
+
+## 一个任务如何在 Meldwork 中推进
+
+1. **选择**一起处理任务的 Agent。
+2. **限定**目标、工作目录、上下文、附件、Skill、知识源和权限。
+3. **协作**：启动 Auto Discussion，让 Agent 讨论方案、接续执行并检查成果；也可选择直接会话或并发回复。
+4. **决策**：在需要补充信息、授权或取舍时介入。
+5. **查看结果**：检查交付物，必要时提出修改，让工作继续推进。
+
+## 协作模式
+
+| 模式 | 运行方式 | 适合场景 |
+| --- | --- | --- |
+| **直接会话** | 一个已选 Agent 在适配器支持时保持对话和原生会话。 | 聚焦研究、写作、分析或执行。 |
+| **并发回复** | 已选 Agent 收到同一份冻结任务快照，并按稳定顺序返回独立回复。 | 在选择方案前比较不同视角。 |
+| **Auto Discussion V4** | Agent 独立提出方案后，接续讨论、请求同伴贡献、在授权范围内执行并检查成果。交付负责人判断任务进度，必要时请求用户决策；支持时保持原生会话。 | 希望减少人工协调的多步骤协作任务。 |
+
+参与者始终由用户选择。从更大候选池自动选人组队不属于当前预览版。
+
+## 过程可回看，工作可继续
+
+Meldwork 在本地保留任务上下文、Agent 回复、运行状态和产物，方便了解任务如何推进、哪里遇到阻塞，以及接下来需要处理什么。Run Ledger 保留阶段、参与者、尝试、产物、恢复状态和人工审批门；诊断工具输出与敏感运行信息留在 Electron 主进程边界内。
+
+过程记录帮助检查协作情况，不代表每条结论都经过事实核验。Agent 的相互检查也不能保证结果正确，重要交付物仍需按实际用途验收。
+
+## General Agent 目录
+
+当适配器和 CLI 版本兼容时，Meldwork 会检测并调用已安装的 Agent 命令。当前目录包括：

+  </tr>
+</table>
+
+已批准的 Agent Connector 和自定义可执行 Agent 使用桌面端的连接器入口。完整的适配器、安装、Provider 和能力矩阵见[桌面端指南](desktop/README.md)。
+
+## 上下文与本地边界
+
+Meldwork 作为本地 Electron 应用运行。对话、群组配置、运行记录和应用管理的附件保存在本地用户数据目录。渲染进程只通过受约束的 preload API 获取校验后的状态；可执行路径、凭据、原生会话引用、Skill 路径和任意 Shell 权限都留在主进程中。
+
+选定的 Agent 仍可能把 Prompt、附件或 Skill 发送到其自身 CLI 凭据对应的模型服务商。知识访问必须明确选择并受边界约束：当前实现支持本地 Obsidian 检索，以及由本地 CLI 管理的飞书或钉钉访问模式。Local-first 描述的是 Meldwork 的数据和协作位置，不代表 Agent 使用的模型服务商一定离线。
+
+## 下载 V1.0.9
+
+Apple 芯片 macOS 用户请前往 [Meldwork V1.0.9 预发布页](https://github.com/Ryder-Sun/Meldwork/releases/tag/Meldwork-V1.0.9)，下载 [`Meldwork-1.0.9-arm64.dmg`](https://github.com/Ryder-Sun/Meldwork/releases/download/Meldwork-V1.0.9/Meldwork-1.0.9-arm64.dmg)。发布页同时提供 ZIP 压缩包和 SHA-256 校验文件。启动应用前，请至少安装一个受支持的本地 Agent CLI。
+
+该预览版安装包使用 ad-hoc 临时签名，未使用 Apple Developer ID 签名，也未进行公证。macOS 首次启动时可能需要在“系统设置 → 隐私与安全性”中选择“仍要打开 / Open Anyway”。
+
+## 从源码运行
+
+前置条件：Node.js `22.12+` 和 npm。
+
+```bash
+npm --prefix frontend ci
+npm --prefix desktop ci
+npm --prefix desktop run dev
+```
+
+分发构建前运行：
+
+```bash
+npm --prefix frontend test
+npm --prefix frontend run build
+npm --prefix frontend run build:desktop
+npm --prefix desktop test
+```
+
+## V1.0.9
+
+自动讨论可根据原生 Agent 的明确完成信号结束发言，并要求所有参与者认可同一版交付物。一轮真实六 Agent 无限轮讨论在九轮后完成，交付物哈希一致。此预览版还改进了 Agent 认证状态、识别 CLI 在标准错误中报告的认证失败，并将知识库图标打包进应用。
+
+已安装 Agent 不代表模型连接可用：OpenClaw 的隔离环境可能无法使用现有原生配置，WorkBuddy CLI 可能需要单独登录，Zcode 需要有效的原生提供方凭据。桌面端和前端回归测试分别通过 1,700 项和 379 项。
+
+## V1.0.8
+
+V1.0.8 将 Kimi 只读问答改为手动权限模式，避免强制进入计划流程；修复 MiMo 末尾文本丢失、原生 CLI 配置变量遗漏，以及发送后 Auto Discussion 模式重置。原生输出持续重复时会取消调用并保留已输出内容。Zcode 保持官方标志和 Pi Agent 前的位置，沿用原生默认配置；WorkBuddy 可以复用在 Meldwork 中选定的桌面已配置模型。
+
+本轮对全部 13 个已安装 CLI 进行了真实调用。使用独立 Magpie 热修网关的五 Agent 无限轮讨论中，14 次原生调用全部完成。当前安装的 Magpie 可能把 `tool_calls:null` 误判为真实工具调用，将 `stop` 改写为 `tool_calls`，导致 OpenCode、MiMo 和 Hermes 持续续写；本次 Meldwork 发布不会安装或重启 Magpie。OpenClaw、Zcode、Gemini、Qwen 和 OpenCodeReview 在本机另有原生配置或认证故障，检测到安装不代表模型连接已可用。回归验证包括桌面测试 1,655 项、前端测试 370 项、Web 与桌面构建及打包验证。无限轮讨论保留进程停滞检测，工作区写入仍需明确授权。
+
+Electron 实机界面另完成一轮五 Agent 无限轮讨论：19 次原生调用全部成功，无失败或自动重试，用时约 12 分钟。发送、完成、切回首页再返回群聊后，自动讨论与不限轮数均保持选中。该验收同样使用独立热修网关，证明流程可完成，不构成响应时长保证，也不代表用户现有网关已修复。

+# Architecture
+
+## Product Boundary
+
+Meldwork is a local Electron desktop product for multi-agent orchestration and review with explicitly selected Skill, image, and knowledge-source context. It has no account system, tenant model, required application server, remote conversation store, email delivery, scheduled jobs, or hosted web surface. Optional Agent, Cloud, and Channel Connectors run behind the Electron main-process trust boundary and are disabled until explicitly configured. The landing page at https://ryder-mhumble.github.io/Meldwork/ is the public marketing surface for search engine and AI assistant discoverability.
+
+The supported product surface is the packaged Electron application. The frontend is a renderer bundle; without the local preload bridge it shows a desktop-required state and cannot operate the workspace.
+
+## Components
+
+| Component | Responsibility | Primary evidence |
+| --- | --- | --- |
+| Vue renderer | Agent-first multi-session UI, direct-session rename/delete, live direct-chat conclusions and inline execution summaries, group-chat result streaming with an expandable per-Agent/right-side trace panel, per-round navigation, background completion markers, first-run carousel, conversation/Skill/image/knowledge composer UI, bounded attachment-preview cache, theme/i18n, user confirmation and input collection | `frontend/src/App.vue`, `frontend/src/components/RunTracePanel.vue`, `frontend/src/composables/useAttachmentPreviews.js`, `frontend/src/desktop.js`, `frontend/src/knowledgeBaseCatalog.js` |
+| Electron preload | Exposes narrow workspace, Human Gate, Cloud control, installer/Skill, attachment, and knowledge-source methods through `window.meldworkDesktop` only to a local `file:` document; Channel ingress has no renderer API | `desktop/src/preload.cjs` |
+| Electron main | Trust boundary for IPC authorization and shutdown gating, persistence, attachment import/preview, Connector registration, Skill and knowledge-source validation, local/Cloud execution, Channel receivers, navigation, sanitized run events, operating-system notifications, and installer control | `desktop/src/main.cjs` |
+| Local workspace | Persists Meldwork conversations, final replies, compact evidence capsules, safe message metadata, task-scoped group Sessions, conversation-scoped direct Sessions, legacy Session migration, Agent-specific transcript deltas, Agent preferences/runtime evidence, and active run coordination | `desktop/src/workspace/local-workspace.cjs` |
+| V4 orchestration | Validates frozen snapshots, phase-aware slots, typed collaboration receipts, negotiated responsibility graphs, work receipts, synthesis recovery, verification, and idempotent commits | `desktop/src/collaboration/orchestration-v4-records.cjs`, `desktop/src/workspace/local-workspace-message-submission.cjs`, `desktop/src/workspace/local-workspace-auto-runner.cjs` and its `local-workspace-auto-runner-*.cjs` parts (see Code Map) |
+| Run Ledger | Atomically checkpoints bounded, sanitized per-run and per-Agent state for stop/crash recovery, marks nonterminal runs and Agent attempts interrupted after restart, supports idempotent reconciliation of missing terminal Agent messages, and purges records with their conversation | `desktop/src/runs/run-ledger.cjs` |
+| Context Pack and delivery stores | Capture immutable, content-addressed Task inputs, attempt-specific approved prompts, exact outbound fingerprints, source hashes, target scope, and native Session provenance | `desktop/src/collaboration/context-pack-store.cjs`, `desktop/src/workspace/local-workspace-context-packs.cjs` |
+| Outcome store | Persists typed Artifacts, Evidence, Findings, and Adoption records separately from diagnostic reasoning and tool summaries | `desktop/src/collaboration/outcome-store.cjs`, `desktop/src/collaboration/outcome-records.cjs` |
+| Human Gate store | Persists permission, budget, and decision requests and their terminal user/system decisions without exposing raw request payloads to the renderer | `desktop/src/gates/human-gate-store.cjs`, `desktop/src/gates/human-gate-coordinator.cjs` |
+| Scheduling and failure policy | Enforces run budgets, per-Agent controls, and one writer at a time within a conversation (conversations never wait for each other); classifies failures (sign-in, rate limit, network, provider, context overflow) and decides retries with `Retry-After`; stops a silent Agent through the invocation watchdog | `desktop/src/runs/run-scheduler.cjs`, `desktop/src/runs/failure-policy.cjs`, `desktop/src/runs/failure-signals.cjs`, `desktop/src/runs/invocation-watchdog.cjs` |

+
+## Code Map
+
+The workspace is composed of small modules around a thin coordinator. A module either owns one piece of state or is a pure function of its inputs; each has a test file with the same name under `desktop/test/`.
+
+**One Agent invocation** (`desktop/src/workspace/local-workspace-agent-invocation.cjs`) is the run lifecycle: lease, run, race against stop and timeout, record the result. It delegates to:
+
+| Module | Owns |
+| --- | --- |
+| `invocation-session.cjs` | The native Agent session of one invocation: resume, adopt a new id, discard and rebuild, record the turn |
+| `invocation-outputs.cjs` | Workspace snapshot before a writable turn, media import and artifact descriptors after it |
+| `invocation-prompt.cjs` | The prompt one Agent receives (frozen, direct chat, group) |
+| `invocation-budget.cjs` | Usage recorded against the run budget |
+| `invocation-failure.cjs` | Why an invocation ended (stopped, timed out, interrupted, cancelled, failed) and the hidden error metadata |
+| `desktop/src/runs/invocation-watchdog.cjs` | Startup, inactivity and stall windows; liveness versus substantive progress |
+| `desktop/src/agents/agent-permission-policy.cjs` | Automatic answers to permission requests; a read-only turn only approves side-effect-free tools |
+| `desktop/src/collaboration/collaboration-receipt.cjs` | Parsing and normalising the control receipt at the end of a turn (lenient for natural discussion, strict for phased V4) |
+| `desktop/src/collaboration/answer-marker-filter.cjs` | Hides control markers while an answer streams |
+
+**Prompts** live in `desktop/src/workspace/prompts/`: `natural-discussion-prompt.cjs` (named sections: brief, writer, owner, routing, receipt), `manual-reply-prompt.cjs` (concurrent replies in a group), and `prompt-contracts.cjs` (the language and deliverable contracts shared by all of them). Direct chats are built by `directPromptFor` in `local-workspace-context.cjs`.
+
+**The automatic run** is `LocalWorkspaceAutoRunner`; its methods are grouped into files by what they do and assembled with `Object.assign` onto the class prototype:
+
+| File | Responsibility |
+| --- | --- |
+| `local-workspace-auto-runner.cjs` | Constructor, `start` and `resume`, run-level helpers |
+| `…-natural-discussion.cjs`, `…-natural-decisions.cjs` | The production path: transcript, prompts, the sequential and agent-led loops, and what happens after each round (owner takeover, ignored routes, peer blockers, missing decisions) |
+| `…-v4-discussion.cjs`, `…-v4-phase.cjs`, `…-v4-results.cjs` | The phased V4 run, one phase, and turning results into receipts and commits |
+| `…-v4-context.cjs`, `…-v4-delivery.cjs`, `…-v4-synthesis.cjs`, `…-v4-outcomes.cjs` | What a run freezes and shares, how context reaches each Agent, synthesis recovery, and the receipts, review issues, convergence and acceptance checks |
+| `…-recovery.cjs` | Retries, pausing a failed Agent for the run, unauthorized-session recovery |
+| `…-collaboration.cjs` | Collaboration records written as a run progresses |
+| `…-task-graph.cjs`, `…-rounds.cjs` | V3 task-graph and V2 round runs, kept only to resume older runs |
+
+Splitting by file did not change any method; the class still shares one `this`. New behaviour should go into a small module with its own tests and be called from the group that owns the topic, not appended to a large method.
+
+## Reliability Rules
+
+- Conversations are independent. A running chat, direct or group, never makes an Agent in another conversation wait, even when both use the same folder and the same Agent. The writer lease is scoped to the conversation; inside one conversation writers still take turns.
+- A failure pauses an Agent for the current run only. Group membership is never rewritten because an Agent failed; a group whose members were all removed by an older build is rebuilt from the Agents that replied in it.
+- Only a definitive sign-in failure marks credentials missing. A refusal that could be a proxy or a tool's own output is retried once and reported as a provider failure.
+- An Agent that was available stays available through an inconclusive readiness probe for ten minutes. A definitive answer applies immediately.
+- A stopped or failed turn keeps a healthy long-lived ACP process and its native session. The process is replaced only when it ignores cancellation or the protocol breaks.
+- Unknown ACP traffic (banners, new update kinds, unknown notifications) is ignored; unknown requests are answered with "method not found". Malformed JSON, invalid responses and invalid permission requests still fail closed.
+- Messages in a group topic carry a dispatch number (`turnSeq`) assigned before the Agent starts, so live and saved replies share one order. Failure and stop notices take the turn's number.
+- A discussion does not end on a malformed receipt, an absent recipient, a peer reporting a blocker or an owner who forgot the decision: those are discarded, handed to the owner, or asked for once.
+
+## Concurrent Collaboration V4
+
+- A group with multiple selected Agents in `manual` mode runs as one concurrent batch. Harness freezes every selected Agent's task snapshot and delivery plan before any Scheduler lease, preserves all selected members, and publishes the batch in stable member order after the barrier. Direct conversations, one-Agent targets, and regeneration keep their existing execution paths.
+- Auto Discussion begins with independent parallel proposals. The selected Agents then challenge the proposal set and negotiate one responsibility graph; every participant must agree to the same normalized plan before work begins. Harness validates and schedules that graph but does not privately assign the responsibilities.
+- The agreed work packages run according to their declared dependencies and produce typed Artifact/Evidence references. Proposal, challenge, work, and verification remain read-only; when workspace writes are enabled, the agreed finalizer is the only synthesis writer. Different Agents independently verify the current candidate.
+- V4 checkpoints phase, slots, attempts, receipts, delivery watermarks, negotiated roles, candidate state, and commit progress. Read-only work can recover automatically at supported boundaries; an unknown writable outcome requires a Human Gate before retry. Stop and cancellation reject late results.
+- V1 manual, V2 Auto Discussion, and V3 Task Graph records remain on their legacy parsers and executors. Renderer snapshots expose only validated public phase, participant, role, progress, and Gate state, never prompts, executable paths, native Session references, or internal snapshot contents.
+
+Automatic participant selection from a larger roster, production remote Agents, enterprise governance, and an Outcome Network are outside the V1.0.2 release boundary.
+
+## Trust Boundaries
+
+1. The renderer is not trusted with Node.js, Agent executable paths, native Agent session IDs or storage paths, attachment paths, Skill paths/contents, raw CLI credentials, arbitrary filesystem reads, or arbitrary process execution. User-selected conversation workdirs and the user-selected Obsidian Vault path are intentional UI-visible paths; pasted image bytes use one exact import payload.
+2. Preload exposes only named IPC methods. Main validates that every request comes from the current main frame and exact bundled frontend file.
+3. Main owns local files, OS dialogs, attachment validation/storage, Skill and knowledge-source discovery/revalidation, Connector approval/registration, Agent discovery, child processes, Cloud observation, Channel authentication, installer downloads, and credential encryption.
+4. Agent CLIs are external processes. They receive a selected working directory, a constrained environment, permission flags, main-resolved image paths, target-scoped immutable Skill snapshots, and validated knowledge snapshots or read-only hints after capability checks.
+5. Agent Connector, Cloud Connector, Channel Connector, and installer destinations are external trust boundaries. Manifests and Connector instances fail closed unless explicitly approved; Channel signatures and Workspace scope are verified before Task delivery.
+6. Harness events expose only allowlisted status, conclusion deltas, reasoning summaries, plans, tool lifecycle summaries, bounded result metadata, and source message IDs. Raw chain-of-thought, commands, executable paths, native session references, credentials, unrestricted stdout/stderr, and arbitrary tool payloads remain outside the renderer and shared Agent context.
+
+## Local Data
+
+| Data | Location | Protection |
+| --- | --- | --- |
+| Meldwork conversations, messages, native session-reference mappings, Agent preferences/runtime evidence | Electron user data: `meldwork-workspace.json` | Local JSON written through main; group native references are keyed by Task and Agent, direct references by conversation and Agent, all remain main-only, and snapshots remove executable paths |
+| Bounded run checkpoints | Electron user data: `meldwork-run-ledger.json` | Atomic private writes; `0600` file, with new parent directories created as `0700`; at most 64 sanitized runs with bounded Agent output/events/source IDs; no raw commands, paths, credentials, or native session references |
+| Immutable Context Packs, delivery records, content blobs, typed outcomes, and Human Gates | Electron user data under `meldwork-private/` | Content-addressed or atomically written main-only records; renderer snapshots expose only bounded IDs, provenance summaries, budgets, and pending Gate choices |
+| Cloud operations and Channel Inbox | Electron user data under `meldwork-private/` | Private `0600` stores keep opaque remote references, idempotency state, signed-event-derived Task data, delivery cursors, Task mappings, and outbound audit records; raw signatures, headers, credentials, and complete IM history are not exposed to the renderer |
+| Imported attachments | Electron user data under `attachments/` | App-owned copy; `0700` directories, `0600` files, type/MIME/size validation, image-dimension checks where applicable, metadata checksum, ID-only renderer access |
+| Knowledge-source preference | Electron user data: `meldwork-knowledge-base.json` | Stores the selected absolute Obsidian Vault path only; written atomically as a private file |
+| Managed OpenClaw state/config | Electron user data under `openclaw-managed/` | Per-scope directories, mode `0700`; config mode `0600`; API key passed by child environment |
+| Theme, locale, and onboarding completion | Renderer `localStorage` | Non-secret UI preferences |
+
+Live renderer events remain transient. Main separately checkpoints a bounded sanitized run snapshot, while final replies and compact evidence capsules are stored with local conversation messages so a group result can reopen its trace without retaining raw tool output. A conclusion already emitted through answer deltas is retained in the terminal failure, timeout, stop, or interruption message. On restart, nonterminal checkpoints become `interrupted`, then every recoverable terminal Agent checkpoint that is not already represented in the conversation is materialized with its recorded status and output. Completed and partial attempts become Agent messages; failed, timed-out, stopped, and interrupted attempts become status-specific system messages. If a matching `agentRunId` message already exists but lacks its Ledger output, reconciliation enriches it once. Writable Agents are never auto-resumed. Persisted attachment references contain safe metadata only, and Skill references contain sanitized target/namespace/slug/name coordinates. Renaming a conversation preserves its native sessions; changing its working directory clears them to prevent cross-workspace resume. Deleting a Meldwork conversation must first remove its Run Ledger records, then remove its app-owned messages, native session-reference mapping, and attachments no longer referenced elsewhere. It does not call a CLI-specific deletion command or remove history stored by Codex, Hermes, or another Agent CLI.
+
+There is no Meldwork-hosted remote data store or application account namespace. Managed OpenClaw paths are isolated by local conversation and working-directory scope inside Electron's per-user data directory. Optional Cloud jobs and Channel deliveries remain owned by their configured external systems while local recovery state stays in main-owned private stores.
+
+## Network Surface
+
+- Agent CLIs may call their own configured model providers.
+- Selected attachments and Skill-influenced prompts may be sent by an Agent CLI to its configured model provider after local validation and capability checks.
+- Feishu and DingTalk readiness probes may invoke their configured local CLIs; a selected Agent may then use those CLI connections with read-only instructions.
+- An explicit Obsidian selection is searched and fetched through the main-owned read-only filesystem Connector, then captured as an immutable snapshot or explicit live reference before Agent invocation.
+- Approved Agent Connectors may contact only their declared outbound destinations and receive main-owned CredentialRefs rather than renderer-provided secrets.
+- Configured Cloud Connectors may submit and observe remote jobs, answer waiting input/permission, cancel idempotently, and fetch declared Artifacts.
+- Configured Channel Connectors may keep a main-process receiver active while the UI window is closed; verified events become scoped Task requests and audited replies rather than copied chat history.
+- The installer may download fixed Hermes/Kimi installer URLs or invoke npm for fixed package names.
+- Credential-free HTTPS links may be opened in the operating-system browser; remote navigation is denied inside the Electron window.
+- The renderer CSP uses `connect-src 'self'` and does not directly call model or application APIs.
+
+## Known Risks And Assumptions
+
+- Writable conversations that share a folder are not coordinated. Two Agents in different conversations can edit the same files at the same time, as two terminals in one directory can. Output capture compares `.meldwork-output/` before and after a run, so when two conversations produce deliverables in the same folder at the same time, one may attach or record a file the other wrote.
+- Installer recipes use mutable upstream packages or scripts and currently do not verify a pinned digest or signature (`desktop/src/agents/installer/agent-installer.cjs`).
+- Conversation history is local but not application-encrypted (`desktop/src/workspace/local-workspace.cjs`).
+- Sanitized Run Ledger checkpoints are local and private but not application-encrypted. The store assumes one Electron main-process writer and recovers only the last persisted bounded checkpoint, not every in-memory event (`desktop/src/runs/run-ledger.cjs`).
+- Conversation deletion is privacy-first across two local JSON stores rather than transactional: Ledger records are removed first; if the workspace write then fails, in-memory conversation state is rolled back and remains retryable, but the deleted trace checkpoints are not recreated.
+- Imported attachment copies are private and integrity-checked but not application-encrypted (`desktop/src/attachments/attachment-store.cjs`).
+- Local Skill files are untrusted prompt input. Main prevents renderer-supplied paths and cross-Agent selection, but a selected Skill can still influence Agent behavior (`desktop/src/skills/local-skill-catalog.cjs`, `desktop/src/workspace/local-workspace.cjs`).
+- Obsidian selections use a main-owned read-only Connector with bounded retrieval, immutable snapshots, and citation hash verification. Generic Feishu and DingTalk access remains CLI-owned and prompt-mediated; their authentication and document permissions are not controlled by Meldwork. Notion, Confluence, Google Drive, and SharePoint are reference-only planned sources and are not active Connectors.
+- Native image support is currently limited to Codex, Hermes, and OpenCode, with different per-run limits; mixed groups fail before execution when they cannot receive equal image context (`desktop/src/agents/cli/cli-adapters.cjs`).
+- Read-only enforcement is owned by the Obsidian Connector for captured selections. Agent workspace and CLI-mediated remote access still depends partly on each upstream CLI honoring its permission flags; Meldwork adds per-CLI hardening where available (`desktop/src/agents/cli/cli-adapters.cjs`).
+- Native Agent authentication and model requests are external dependencies; Meldwork cannot guarantee their availability or data handling.
+- Agent/Cloud/Channel Connector contracts validate provenance, scope, and idempotency, but the external implementation must honor its CredentialRef, outbound destination, cancellation, and signature-verification obligations. The production build registers no Cloud or Channel Connector by default.
+- macOS packaging uses ad-hoc signing for local validation, not a notarized public release (`desktop/scripts/after-pack.cjs`).
+
+## Capability Absences
+
+- No email sending, so there is no `emails.md`.
+- No cron or scheduled background work, so there is no `cron.md`.
+- No supported public or indexable routes in the app itself, so there is no `seo.md`. The landing page at https://ryder-mhumble.github.io/Meldwork/ serves as the public discoverability surface for search engines and AI assistants.

+# Meldwork 桌面客户端
+
+Meldwork 是完全本地运行的 Electron 客户端。它直接加载仓库中的桌面前端，在 Electron
+主进程中检测和调用本机 Agent CLI，不需要登录、JWT、远端平台、Docker 或云端服务。
+
+本地群聊、消息、群组配置和 CLI 会话引用保存在 Electron 用户数据目录。渲染进程只通过
+`window.meldworkDesktop` 调用经过约束的 preload API，不会获得可执行文件路径、Provider
+API Key 或任意 Shell 执行能力。
+
+支持检测和调用以下本机 Agent CLI：
+
+- Codex
+- Hermes
+- OpenClaw
+- WorkBuddy
+- Zcode
+- Pi Agent
+- Kimi Code
+- MiMo Code
+- Claude Code
+- Gemini CLI
+- OpenCode
+- Qwen Code
+- OpenCodeReview
+
+Agent 管理面板提供经过白名单约束的安装入口。安装命令和下载地址由主进程固定，不会根据页面
+输入执行任意命令。内置 Agent 通过各自支持的原生权限模式或 Meldwork 托管工具策略执行；无法
+满足当前权限契约的 Agent 会安全失败。群聊级工作目录写入默认关闭，只有用户明确授权后才会
+切换为写入模式。Kimi 在只读对话中通过 Agent Client Protocol 的 `plan` 模式运行；用户明确
+开启写入权限后，才切换到 Kimi 原生的 `stream-json --prompt` 模式。
+
+## 首次启动与本地 Agent 检测
+
+V1.0.7 GitHub 预发布使用 ad-hoc 临时签名，不使用 Apple Developer ID，也不提交 Apple 公证。
+如果 macOS 首次启动时拦截候选应用，请打开
+“系统设置 → 隐私与安全性”，找到 Meldwork 的拦截提示，点击“仍要打开 / Open Anyway”，
+再确认启动。
+
+首次启动会显示三页引导轮播，依次介绍本地 Agent 检测、多 Agent 协作、Skill 与文件上下文。
+客户端在引导打开时执行唯一一次启动刷新；检测任务真正结束前“开始使用”按钮保持禁用，不会
+用固定计时器伪装完成。检测成功或失败后才释放按钮。完成或关闭引导后会在渲染层本地记录状态，
+后续启动直接进入工作台；Agent 仍可在管理面板中重新检测。
+
+## 并发协作 Harness V4
+
+群聊中选择多个 Agent 后，“并发回复”会在任何 Agent 获取调度资源前冻结同一份任务快照，让全部已选 Agent 独立生成，并在批次屏障后按稳定顺序提交。
+
+Auto Discussion 会依次进入独立提案、交叉质询与职责协商、分工执行、单写者整合和独立复核。职责图由 Agent 协商产生，Harness 只负责验证全员同意的同一份计划、依赖、权限、回执、恢复和提交边界，不在模型之外私下分配工作。参与者仍由用户选定；从更大候选池自动选人组队不属于当前版本。
+
+## `@` Skill 引用
+
+在消息输入框输入 `@` 或点击 `@` 按钮，可以选择当前目标 Agent 本机已发现的 Skill。列表只
+返回清洗后的 Agent、命名空间、slug 和显示名称，不返回 Skill 文件路径或内容。一次消息最多
+选择 4 个 Skill；主进程会在发送前按目标 Agent 重新扫描并验证选择，跨 Agent 冒用、过期条目
+或前端构造的任意路径都会被拒绝。Hermes 使用原生 `--skills` 参数预加载已验证 Skill；其他
+Agent 只会收到属于自己的 Skill 坐标提示，不会收到其他目标的选择。
+
+## 文件与多模态附件
+
+消息输入框支持系统文件选择器、剪贴板图片以及把文件拖入输入区。当前接受经过 MIME、扩展名和
+文件签名交叉校验的 PNG、JPEG、音视频、PDF、文本、Markdown、常见代码与配置文件、Office
+文档和常见压缩容器；一条消息最多 4 个附件，各格式使用独立大小上限。附件会复制到 Electron
+用户数据目录下的私有存储，工作区消息只保存 `id`、文件名、MIME 类型和大小；渲染层不能读取
+附件路径，只能通过窄 IPC 请求预览或使用系统默认应用打开文件。
+
+Agent 原生支持的图片会按其数量限制直接传递。其他文件，或超过某个 Agent 原生媒体能力的附件，
+会在运行期间暂存为工作区内的只读输入文件，并在运行结束后清理；提示词明确要求只读取、不得执行
+附件。未发送附件、删除会话后的无引用附件和异常导入残留由主进程回收。
+
+## Provider 配置
+
+Agent 使用各自本机的原生鉴权、Provider 和默认模型配置。Meldwork 不要求统一 Provider，
+也不会将一个 Agent 的密钥注入其他 Agent。WorkBuddy 桌面账号的加密登录不能直接供独立
+CLI 解锁；可在 Meldwork 中选择桌面配置里已有且已配置鉴权的模型。
+Meldwork 仅保存模型标识，运行时由主进程读取原生配置，不向渲染层返回密钥。
+Zcode 沿用默认配置；若其默认 Provider 缺少 API Key，需要先修复本机原生配置。
+
+## 本地 CLI 支持矩阵
+
+| Agent | 检测命令 | macOS 安装 | Windows 安装 | 用户 Provider |
+| --- | --- | --- | --- | --- |
+| Codex | `codex` | npm：`@openai/codex@latest` | npm：`@openai/codex@latest` | 不注入；沿用 Codex 本机配置 |

+| OpenClaw | `openclaw` | npm：`openclaw@latest` | npm：`openclaw@latest` | 沿用本机配置 |
+| WorkBuddy | `codebuddy` | npm：`@tencent-ai/[email protected]` | npm：`@tencent-ai/[email protected]` | 可选择桌面已配置模型 |
+| Zcode | `zcode` | 官方 CLI 安装 | 官方 CLI 安装 | 沿用默认配置 |
+| Pi Agent | `pi` | npm：`@mariozechner/pi-coding-agent` | npm：`@mariozechner/pi-coding-agent` | 沿用本机配置 |
+| Kimi Code | `kimi` | 官方 `install.sh` | 官方 `install.ps1` | 不注入；沿用 Kimi 本机配置 |
+| MiMo Code | `mimo` | npm：`@mimo-ai/cli@latest` | npm：`@mimo-ai/cli@latest` | 不注入；沿用 MiMo 本机配置，按授权使用 `plan` / `build` 模式 |
+| Claude Code | `claude` | npm：`@anthropic-ai/claude-code@latest` | npm：`@anthropic-ai/claude-code@latest` | 不注入；沿用 Claude 本机配置 |
+| Gemini CLI | `gemini` | npm：`@google/gemini-cli@latest` | npm：`@google/gemini-cli@latest` | 不注入；沿用 Gemini 本机配置 |
+| OpenCode | `opencode` | npm：`opencode-ai@latest` | npm：`opencode-ai@latest` | 不注入；沿用 OpenCode 本机配置 |
+| Qwen Code | `qwen` | npm：`@qwen-code/qwen-code@latest` | npm：`@qwen-code/qwen-code@latest` | 沿用本机配置 |
+| OpenCodeReview | `ocr` | npm：`@alibaba-group/open-code-review@latest` | npm：`@alibaba-group/open-code-review@latest` | 沿用本机配置 |
+
+macOS 会在当前 `PATH` 之外搜索 Volta、pnpm、fnm、asdf、mise、bun、
+`~/.local/bin`、`~/.kimi-code/bin`、`~/.mimocode/bin`、Homebrew 等常见目录。Windows 会额外搜索用户 npm、
+WindowsApps、Node.js、WorkBuddy、Chocolatey 和 Scoop 目录，并按 `PATHEXT` 解析命令。
+
+Hermes 和 Kimi 的安装脚本来自固定 HTTPS 白名单地址；客户端不内置脚本副本，因此离线环境
+不能使用这两个一键安装入口。当前自动安装面向 macOS 和 Windows，Windows 安装流程仍需在
+真实 Windows 设备上做发布前验证。
+
+## 目录结构
+
+- `src/agents/`：Agent 兼容层、路由、运行时、CLI、安装器、连接器
+- `src/attachments/`：附件、内容存储、图片尺寸校验
+- `src/collaboration/`：对话、上下文包、产物、任务图
+- `src/workspace/`：本地工作区与自动调度；自动运行器的通用失败、重试和等待语义位于 `local-workspace-auto-runner-support.cjs`
+- `src/runs/`：运行、预算、事件、调度、日志
+- `src/knowledge/`：知识库与知识连接器
+- `src/skills/`：Skill 目录、快照、信任
+- `src/security/`：私有文件与敏感信息脱敏
+- `test/`：按同名领域镜像组织测试，`support/` 放测试辅助代码；测试发现与 suite 选择位于 `scripts/test-discovery.cjs`
+
+## 本地开发
+
+```bash
+cd desktop
+npm install
+npm run dev
+```
+
+可选环境变量：
+
+- `MELDWORK_CODEX_SANDBOX`：Codex 默认沙箱模式，支持 `read-only` 和
+  `workspace-write`；未设置或值不受支持时使用 `read-only`。
+
+## 测试与打包
+
+```bash
+npm test
+npm run pack
+npm run dist
+npm run dist:public
+```
+
+`pack` 用于生成未打包应用并验证 Electron 产物；`dist` 生成 V1.0.7 GitHub 预发布候选使用的 ad-hoc 签名 DMG 和 ZIP。这些产物不具备 Developer ID 信任链且未公证，不能声称通过 Gatekeeper。
+
+`dist:public` 是未来正式签名公开发行的专用命令：它要求
+Developer ID 证书和完整公证凭据，强制代码签名，在签名后校验永久 Bundle ID、Team ID 与
+hardened runtime，并调用 Apple 公证；任一条件不满足都会失败。产物输出到 `desktop/dist/`，
+其中包含本地前端，不依赖服务器或容器。
