+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the project maintainer at <359807859@qq.com>. All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.
+
+## Attribution

+# Contributing to Reasonix
+
+Thanks for showing up. Reasonix is a small, opinionated codebase
+maintained primarily by [@esengine](https://github.com/esengine);
+PRs are welcome, but read this first so the round-trip is short.
+
+## Setup
+
+```sh
+git clone https://github.com/esengine/reasonix
+cd reasonix
+npm install
+npm run dev          # tsx src/cli/index.ts — live source
+```
+
+Node ≥ 22. No global install needed during development.
+
+For stack, layout, scripts, see [`REASONIX.md`](./REASONIX.md).
+
+## Proposing changes
+
+- **Bug fixes** — go ahead and open a PR. Include a reproduction.
+- **New features / behavior changes** — open an issue first to align
+  on scope and approach. Reasonix tries to stay small; "we could add
+  X" PRs that arrive cold are usually rejected or scoped down.
+- **External MCP servers, plugins, presets** — a thin wrapper is
+  fine; a sprawling integration is better hosted as a separate
+  package that depends on `reasonix`.
+
+## Code rules
+
+These are enforced by review and (where possible) by
+`tests/comment-policy.test.ts` — which runs under `npm run verify`
+and gates pre-push.
+
+### Comments — default is none
+
+Write a comment ONLY when **why** is non-obvious and removing the
+comment would confuse a future reader. Justified examples:
+
+- a hidden constraint (`// Yoga miscounts wrap → must clamp to width-1`)
+- a workaround for a specific bug
+- a subtle invariant the type system can't express
+
+Don't write:
+
+- **What the code does.** Names already say it. No `// when x is positive`
+  above `if (x > 0)`.
+- **Module-level essays.** Multi-paragraph docstrings at the top of a
+  file are dead weight. Two short lines max.
+- **Conversation history.** No "user reported X", "screenshot showed
+  Y", "v0.13.2 introduced Z". That belongs in commits / PR text.
+- **Section banners.** `// ─── helpers ───` is noise; group by export.
+- **Restated parameter docs.** If `function pad(f, top, right, bottom,
+  left)`, no `@param top - top padding`.
+
+If a comment is justified, **one line is almost always enough**.
+Comments needing 4+ lines usually mean the code itself needs to be
+clearer (rename, extract, simplify) before any comment is added.
+
+### TypeScript
+
+- Strict mode. No `any` without a `// biome-ignore` and a reason.
+- Prefer narrow types over option bags; if a function takes 5+
+  optional flags, split the responsibilities.
+- Don't re-export types just so two files can share them — move the
+  type to the file that owns the concept.
+
+### Libraries over hand-rolled
+
+If a problem has a well-maintained npm library, use it. Specific
+landmines this project has hit:
+
+- Visual width / unicode width → `string-width`
+- Grapheme segmentation → `Intl.Segmenter`
+- ANSI strip → use what `string-width` ships with
+- Color → use `theme.ts` constants, not raw hex in component code
+
+If a lib is missing a case, file the issue upstream and add a thin
+wrapper — don't fork a local table.
+
+### Files
+
+- One responsibility per file. New code goes in new files when an
+  existing one is already large.
+- File header comment: zero or one line.
+- No `index.ts` re-exports unless they meaningfully shrink the
+  public surface.
+- Don't create new `*.md` documentation files unless explicitly
+  asked.
+
+### Errors / fallbacks
+
+- Don't add try/catch for "internal" errors. Trust your own code.
+- Don't validate things the type system already proves.
+- Boundary code (user input, network, FS) does validate; everything
+  else trusts.
+- No "graceful fallback" silently masking bugs. Log + crash >
+  silent wrong output.
+
+### Tests
+
+- Test what's hard to verify by reading the code: invariants, edge
+  cases, regressions.
+- Don't test type signatures or that `function returns X` (the type
+  system does that).
+- Don't write tests just to bump coverage.
+
+### Git / commits
+
+- Imperative mood, scope tag, why-not-what. See recent `git log`
+  for the pattern (`feat(ui): …`, `fix(loop): …`, `chore(release):
+  …`).
+- One logical change per commit; refactors land separately from
+  features.
+- No `Co-Authored-By: Claude` trailer.
+
+## PR expectations
+
+- Branch off `main`. One logical change per PR.
+- `npm run verify` must pass locally (lint + typecheck + tests +
+  comment-policy gate). Pre-push hook runs this; CI runs it on
+  Node 22.
+- Don't touch `CHANGELOG.md` — release notes are written by the
+  maintainer at release time, drawn from commit history. PR
+  descriptions are the authoritative record while the work is in
+  flight.
+
+## Code review
+
+Reasonix prefers blunt, fast review. Expect:
+
+- Line-level pushback on comments that explain *what* instead of *why*.
+- Pushback on new abstractions / flags introduced before there are
+  two real call sites.
+- Pushback on hand-rolled implementations of problems a maintained
+  npm library already solves.
+
+None of this is personal — it's how the codebase stays small.
+
+## Releasing (maintainers)
+
+1. Bump `package.json` version.
+2. Add `## [X.Y.Z] — <date>` to `CHANGELOG.md` with a hand-written
+   summary drawn from `git log` since the prior tag.
+3. `chore(release): X.Y.Z — <one-line summary>` commit.
+4. `git tag -a vX.Y.Z -m "..."`, push commit + tag.
+5. Wait for CI green, then `npm publish`.
+
+## Reporting security issues
+
+See [`SECURITY.md`](./SECURITY.md). Short version: don't open a public issue, email the maintainer privately.

-`read_file` / `write_file` / `edit_file` / `list_directory` /
-`search_files` / `directory_tree` / `get_file_info` /
-`create_directory` / `move_file` tools, all sandboxed — any path that
-resolves outside the launch root (including `..` and symlink escapes)
-is refused. Plus `run_command` with a read-only allowlist; anything
-state-mutating (`npm install`, `git commit`, …) is gated behind a
-confirmation picker.

-```
+<details>
+<summary><strong>Why DeepSeek-only? — the cache economics</strong></summary>
 
-If an `edit_file` SEARCH block doesn't match the file byte-for-byte,
-the edit is refused loudly rather than fuzzy-matched. The model sees
-the error and retries — silent wrong edits are worse than visible
-rejections.
+Cheap tokens alone is half the story. DeepSeek's prefix-cache is **byte-stable**: the cache fingerprints from byte 0 of the prompt. Reasonix's loop is engineered around that — append-only growth, no re-ordering, no marker-based compaction — so the cache prefix survives every tool call.
 
-### Plan mode — review before executing
+By comparison, Claude Code is built around Anthropic's `cache_control` markers (a fundamentally different mechanic). Pointing it at DeepSeek's Anthropic-compat endpoint keeps the cheap tokens but loses the cache hits — markers are ignored, and the underlying prefix isn't byte-stable. Generic-backend tools (Aider / Cline / Continue) hit the same wall from the other direction: their compaction patterns destroy byte stability.
 
-For anything bigger than a typo, the model is encouraged to propose a
-markdown plan first. You'll see a picker with **Approve / Refine /
-Cancel**:
+At DeepSeek's pricing — $0.07/Mtok uncached, $0.014/Mtok cached — **the difference between 50% and 94% hit is roughly 2.5× on input cost alone.** Same model, same API; the loop's invariants are what changed.
 
-```
-reasonix code › 把 auth 从 JWT 迁移到 session cookies
+A few DeepSeek-specific fixes generic loops miss:
 
-▸ plan submitted — awaiting your review
-────────────────────────────────────────
-## Summary
-Swap JWT middleware for session cookies, keep user table intact.
-
-## Files
-- src/auth/middleware.ts — replace `verifyJwt` with `readSession`
-- src/auth/session.ts — new file, in-memory store + signed cookie
-- src/routes/login.ts — return Set-Cookie instead of a token
-- tests/auth/*.test.ts — update fixtures
-
-## Risks
-- Existing logged-in users get logged out (no migration).
-- Session store is in-memory; restart clears sessions.
-────────────────────────────────────────
-  ▸ Approve and implement
-    Refine — explore more
-    Cancel
-```
-
-**Force it** with `/plan` — enters an explicit read-only phase where
-the model *must* submit a plan before any edit or non-allowlisted
-shell call will execute. Use for high-stakes changes you want to
-audit before the model touches disk. `/plan off` or picker
-Approve/Cancel exits.
-
-### `/commit` — stage + commit in one step
-
-```
-reasonix code › /commit "fix: findByEmail case-insensitive"
-▸ git add -A && git commit -m "fix: findByEmail case-insensitive"
-  [main a1b2c3d] fix: findByEmail case-insensitive
-```
-
-### Things to try
-
-- `/tool 1` — dump the last tool call's full output (when the 400-char
-  inline clip isn't enough).
-- `/think` — see the model's full R1 reasoning for the last turn
-  (reasoner preset only).
-- `/undo` — roll back the last applied edit batch.
-- `/new` — start fresh in the same directory without losing the
-  session file.
-- `npx reasonix code --preset max` — R1 + 3-way self-consistency
-  branching for gnarly refactors.
-- `npx reasonix code src/` — narrower sandbox (only `src/` is
-  writable).
-- `npx reasonix code --no-session` — ephemeral; nothing saved.
-
-### `reasonix stats` — how much did you actually save?
-
-Every turn `reasonix chat|code|run` runs appends a compact record
-(tokens + cost + what Claude Sonnet 4.6 would have charged) to
-`~/.reasonix/usage.jsonl`. `reasonix stats` with no args rolls that
-log into today / week / month / all-time windows:
-
-```
-Reasonix usage — /Users/you/.reasonix/usage.jsonl
-
-            turns  cache hit    cost (USD)      vs Claude     saved
-----------------------------------------------------------------------
-today           8      95.1%     $0.004821        $0.1348      96.4%
-week           34      93.8%     $0.023104        $0.6081      96.2%
-month         127      94.2%     $0.081530        $2.1452      96.2%
-all-time      342      94.0%     $0.210881        $5.8934      96.4%
-```
-
-Privacy: only tokens, costs, and the session name you chose land
-in the file. No prompts, no completions, no tool arguments.
-`reasonix stats <transcript>` keeps the old per-file summary
-(assistant turns + tool calls) for scripts that already use it.
-
-### Staying current
-
-The panel header shows the running version next to `Reasonix` (e.g.
-`Reasonix v0.4.22 · model …`). A quiet 24-hour background check against
-the npm registry surfaces a yellow `update: X.Y.Z` on the right side
-of the same row when a newer version has been published. No blocking,
-no nagging — the check runs once per day max and is silent on failure
-(offline, firewall, etc.).
-
-```bash
-reasonix update             # print current vs latest, run `npm i -g reasonix@latest`
-reasonix update --dry-run   # print the plan without running anything
-```
-
-Running via `npx`? The command detects that and prints a
-cache-refresh hint instead — npx picks up the newest version on
-its next invocation automatically.
-
-### Project conventions — `REASONIX.md`
-
-Drop a `REASONIX.md` in the project root and its contents are pinned
-into the system prompt every launch. Committable team memory — house
-conventions, domain glossary, things the model keeps forgetting:
-
-```bash
-cat > REASONIX.md <<'EOF'
-# Notes for Reasonix
-- Use snake_case for new Python modules; legacy camelCase modules keep their style.
-- `cargo check` is in the auto-run allowlist; full `cargo test` needs confirmation.
-- The `api/` dir mirrors `backend/` — keep schemas in sync.
-EOF
-```
-
-Re-launch (or `/new`) to pick it up; the prefix is hashed once per
-session to keep the DeepSeek cache warm. `/memory` prints what's
-currently pinned. `REASONIX_MEMORY=off` disables every memory source
-for CI / offline repro.
-
-### User memory — `~/.reasonix/memory/`
-
-A second, **private per-user** memory layer lives under your home
-directory. Unlike `REASONIX.md` it's never committed, and the model
-can write to it itself via the `remember` tool. Two scopes:
-
-- `~/.reasonix/memory/global/` — cross-project (your preferences,
-  tooling).
-- `~/.reasonix/memory/<project-hash>/` — scoped to one sandbox root
-  in `reasonix code` (decisions, local facts, per-repo shortcuts).
-
-Each scope keeps an always-loaded `MEMORY.md` index of one-liners
-plus zero or more `<name>.md` detail files (loaded on demand via
-`recall_memory`). Writes land immediately; pinning into the system
-prompt takes effect on next `/new` or launch so the cache prefix
-stays stable for the current session.
-

-reasonix code › 我用 bun 而不是 npm，请以后都用 bun 跑构建
-
-assistant
-  ▸ tool<remember> → project/bun_build saved
-    "Build command on this machine is `bun run build`"
-```
-
-**Slash**: `/memory` · `/memory list` · `/memory show <name>` ·
-`/memory forget <name>` · `/memory clear <scope> confirm`.
-**Model tools**: `remember(type, scope, name, description, content)` ·
-`forget(scope, name)` · `recall_memory(scope, name)`.
-
-Project scope is only available inside `reasonix code` (needs a real
-sandbox root to hash); plain `reasonix` gets the global scope only.
-
-### Skills — user-authored prompt packs
-
-Skills are prose instruction blocks you drop on disk. Reasonix pins
-their names + one-line descriptions into the system prompt; the
-model can call `run_skill({name: "..."})` on its own when a match
-fits, or you can type `/skill <name> [args]` to run one manually.
-
-Two scopes, same layout as user memory:
-
-- `<project>/.reasonix/skills/` — per-project skills (commit them to
-  share with your team, or add to `.gitignore` for personal drafts).
-- `~/.reasonix/skills/` — global skills available everywhere.
-
-Either layout works: `<name>/SKILL.md` (preferred — can bundle
-additional assets alongside) or flat `<name>.md`.
-
-```markdown
----
-name: review
-description: Review uncommitted changes and flag risks
----
-
-Run `git diff` on staged and unstaged changes. Summarize what each
-hunk does, call out potential regressions, and list files that might
-need additional tests. Don't propose edits unless I ask.
-```
-
-Use it:
-
-```
-reasonix code › /skill review
-▸ running skill: review
-assistant
-  ▸ tool<run_command> → git diff --cached
-  ▸ 3 改动，1 个需要回归测试 …
-```
-
-Or let the model pick autonomously — because the skill's name +
-description are pinned in the prefix, asking "帮我看下未提交的改动有没
-有风险" triggers `run_skill({name: "review"})` without you typing the
-slash command.
-
-**Slash**: `/skill` (list) · `/skill show <name>` · `/skill <name>
-[args]` (inject body as user turn).
-
-**Deliberately not tied** to any other client's directory convention
-(`.claude/skills`, etc.) — Reasonix is model-agnostic at the
-conversation layer. Any SKILL.md you author works; the body is
-prose, so skills authored for other tools usually port over unchanged
-(Reasonix's tool names differ — `filesystem` / `shell` / `web` — but
-the model reads the instructions and picks our equivalents).
-
-### Hooks — automate around tool calls and turns
-
-Drop a `settings.json` under `.reasonix/` (project or `~/`) and
-Reasonix will fire shell commands at four well-known points in
-the loop: before a tool runs, after a tool returns, before your
-prompt reaches the model, and after the turn ends.
-
-```json
-// <project>/.reasonix/settings.json   ← committable
-// ~/.reasonix/settings.json           ← per-user
-{
-  "hooks": {
-    "PreToolUse":       [{ "match": "edit_file|write_file", "command": "bun scripts/guard.ts" }],
-    "PostToolUse":      [{ "match": "edit_file", "command": "biome format --write" }],
-    "UserPromptSubmit": [{ "command": "echo $(date +%s) >> ~/.reasonix/prompts.log" }],
-    "Stop":             [{ "command": "bun test --run", "timeout": 60000 }]
-  }
-}
-```
-
-Each hook is a shell command. Reasonix invokes it with stdin = a
-JSON envelope describing the event:
-
-```json
-{ "event": "PreToolUse", "cwd": "/path/to/project",
-  "toolName": "edit_file", "toolArgs": { "path": "src/x.ts", "..." } }
-```
-
-Exit code drives the decision:
-
-- **0** — pass; loop continues normally
-- **2** — block (only on `PreToolUse` / `UserPromptSubmit`); the
-  hook's stderr becomes the synthetic tool result the model sees,
-  or the prompt is dropped entirely
-- **anything else** — warn; loop continues, stderr renders as a
-  yellow row inline
-
-`match` is anchored regex on the tool name; `*` or omitted matches
-every tool. Project hooks fire before global hooks. Default
-timeouts: 5s for blocking events, 30s for logging events; per-hook
-`timeout` overrides.
-
-**Slash**: `/hooks` (list active hooks) · `/hooks reload` (re-read
-`settings.json` from disk without losing your session).
-
-### Staying current from inside the TUI
-
-`/update` inside a running session shows your current version, the
-last-resolved latest version (from the quiet 24h background check),
-and the shell command to run. The slash does *not* spawn
-`npm install` — stdio:inherit into a running Ink renderer corrupts
-the display. Exit the session and run `reasonix update` in a
-fresh shell when you actually want to install.
-
----
-
-## `reasonix` — also works as general chat
-
-Same TUI, no filesystem tools unless you opt in via MCP. Good for
-drafting, Q&A, schema design, architecture discussions, or driving
-your own MCP servers. Sessions persist per name under
-`~/.reasonix/sessions/`.
-
-```bash
-npx reasonix                             # uses saved config + wizard-selected MCP
-npx reasonix --preset smart              # reasoner + R1 harvest for this run
-npx reasonix --session design            # named session — resume later with --session design
-```
-
-Bridge your own MCP servers on the fly:
-
-```bash
-npx reasonix \
-  --mcp "fs=npx -y @modelcontextprotocol/server-filesystem /tmp/safe" \
-  --mcp "kb=https://mcp.example.com/sse"
-```
-
-MCP tools go through the same Cache-First + repair + context-safety
-plumbing as native tools — 32k result cap, live progress-notification
-rendering, retries.

-
-## Commands inside the session
-
-**Core**
-
-| command | what it does |
-|---|---|
-| `/help` · `/?` | full command reference with hints |
-| `/status` | current model · flags · context · session |
-| `/new` · `/reset` | fresh conversation in the same session |
-| `/clear` | clear visible scrollback only (log kept) |
-| `/retry` | truncate and resend your last message (fresh sample) |
-| `/exit` · `/quit` | quit |
-
-**Model**
-
-| command | what it does |
-|---|---|
-| `/preset <fast\|smart\|max>` | one-tap bundle (model + harvest + branch) |
-| `/model <id>` | switch DeepSeek model (`deepseek-chat`, `deepseek-reasoner`) |
-| `/harvest [on\|off]` | toggle R1 plan-state extraction |
-| `/branch <N\|off>` | run N parallel samples per turn, pick best (N ≥ 2) |
-| `/think` | dump the last turn's full R1 reasoning |
-
-**Context & tools**
-
-| command | what it does |
-|---|---|
-| `/mcp` | list attached MCP servers and their tools |
-| `/tool [N]` | dump the Nth tool call's full output (1 = latest) |
-| `/compact [cap]` | shrink oversized tool results in the log |
-
-**Memory & skills**
-
-| command | what it does |
-|---|---|
-| `/memory` | show pinned memory (REASONIX.md + ~/.reasonix/memory) |
-| `/memory list` · `show <name>` · `forget <name>` · `clear <scope> confirm` | manage the store |
-| `/skill` · `/skill list` | list discovered skills (project + global) |
-| `/skill show <name>` | dump one skill's body |
-| `/skill <name> [args]` | run a skill (inject body as user turn) |
-
-**Sessions**
-
-| command | what it does |
-|---|---|
-| `/sessions` | list saved sessions (current marked with `▸`) |
-| `/forget` | delete the current session from disk |
-| `/setup` | reconfigure (exit and run `reasonix setup`) |
-
-**Code mode only** (`reasonix code`)
-
-| command | what it does |
-|---|---|
-| `/apply` | commit the pending SEARCH/REPLACE blocks to disk |
-| `/discard` | drop the pending edit blocks without writing |
-| `/undo` | roll back the last applied edit batch |
-| `/commit "msg"` | `git add -A && git commit -m "msg"` |
-| `/plan [on\|off]` | toggle read-only plan mode |
-| `/apply-plan` | force-approve a pending plan |
-
-**Keyboard**
-
-- `Enter` — submit
-- `Shift+Enter` / `Ctrl+J` — newline (multi-line paste also supported;
-  `\` + Enter as a portable fallback)
-- `↑` / `↓` — walk prompt history while idle; navigate slash-autocomplete
-- `Tab` / `Enter` on a `/foo` prefix — accept the highlighted suggestion
-- `Esc` — abort the current turn (stops the API call, cancels any
-  in-flight tool, rejects pending MCP requests)
-- `y` / `n` on confirm prompts — hotkey accept / reject
-
----
-
-## Sessions and safety nets
-
-- Sessions live as JSONL under `~/.reasonix/sessions/<name>.jsonl`
-  (per directory for `reasonix code`). Every message appended
-  atomically; `Ctrl+C` never loses context.
-- Tool results are capped at 32k chars per call. Oversized sessions
-  self-heal on load (shrinks + rewrites the file).
-- Malformed `assistant.tool_calls` / `tool` pairing is validated on
-  every outgoing API call so a corrupted session can't keep 400ing.
-- Context gauge turns yellow at 50%, red at 80% with a `/compact`
-  nudge. Approaching the 131k window triggers an automatic
-  compaction attempt before falling back to a forced summary.
-- The `reasonix code` sandbox refuses any path that resolves outside
-  the launch directory, including symlink escape and `..` traversal.
-
-### Troubleshooting: duplicate rows / ghost rendering
-
-Some Windows terminals (Git Bash / MINTTY / winpty-wrapped shells)
-don't fully implement the ANSI cursor-up escapes Ink uses to repaint
-the live spinner region. Symptom: spinners, streaming previews, or
-tool-result rows print multiple copies into scrollback instead of
-overwriting in place.
-
-If you hit this, run with plain mode:
-
-```bash
-REASONIX_UI=plain npx reasonix code
-```
-
-Plain mode suppresses live/animated rows and disables the internal
-tick timer. You lose the streaming preview and spinners but gain
-stable scrollback. Windows Terminal, PowerShell 7 in Windows
-Terminal, and WezTerm don't need this opt-out.
-
----
-
-## Web search — on by default
-
-The model has two web tools the moment you launch: `web_search` and
-`web_fetch`. No flag, no API key, no signup. When you ask about
-something the model wasn't trained on (new releases, current events,
-obscure APIs), it decides to call `web_search` on its own; if a
-snippet isn't enough it follows up with `web_fetch`.
-
-Backed by **Mojeek**'s public search page — an independent web
-index, bot-friendly, no cookies/sessions. Coverage on niche or very
-recent queries can be thinner than Google/Bing, but it's reliable
-from scripts. (DDG was the original backend but started serving
-anti-bot pages in 2026.)
-
-**Turn it off** (offline mode / privacy / CI):
-
-```json
-// ~/.reasonix/config.json
-{ "apiKey": "sk-…", "search": false }
-```
-
-```bash
-REASONIX_SEARCH=off npx reasonix code
-```
-
-**Bring your own** (Kagi, SearXNG, internal caches): implement the
-`WebSearchProvider` interface and call
-`registerWebTools(registry, { provider })` yourself, or bridge an
-existing MCP search server via `--mcp`.
-
----
-
-## MCP — bring your own tools
-
-Any [MCP](https://spec.modelcontextprotocol.io/) server works. The
-wizard lets you pick from a catalog, or drive it by flag:
-
-```bash
-# stdio (local subprocess)
-npx reasonix --mcp "fs=npx -y @modelcontextprotocol/server-filesystem /tmp/safe"
-
-# multiple at once
-npx reasonix \
-  --mcp "fs=npx -y @modelcontextprotocol/server-filesystem /tmp/safe" \
-  --mcp "demo=npx tsx examples/mcp-server-demo.ts"
-
-# HTTP+SSE (remote / hosted)
-npx reasonix --mcp "kb=https://mcp.example.com/sse"
-```
-
-`reasonix mcp list` shows the curated catalog. `reasonix mcp inspect
-<spec>` connects once and dumps the server's tools / resources /
-prompts without starting a chat. Progress notifications from
-long-running tools (2025-03-26 spec) render live as a progress bar
-in the spinner.
-
-Supported transports: **stdio** (local command) and **HTTP+SSE**
-(remote, MCP 2024-11-05 spec).
-

-
-## Benchmarks — verify the cache-hit claim yourself
-
-Every abstraction here earns its weight against a DeepSeek-specific
-property — dirt-cheap tokens, R1 reasoning traces, automatic prefix
-caching, JSON mode. Generic wrappers leave these on the table.
-
-| | Reasonix default | generic frameworks |
+| Generic loops assume | DeepSeek actually does | Reasonix's fix |
 |---|---|---|
-| Prefix-stable loop (→ 85–95% cache hit) | yes | no (prompts rebuilt each turn) |
-| Auto-flatten deep tool schemas | yes | no (DeepSeek drops args) |
-| Retry with jittered backoff (429/503) | yes | no (custom callbacks) |
-| Scavenge tool calls leaked into `<think>` | yes | no |
-| Call-storm breaker on identical-arg repeats | yes | no |
-| Live cache-hit / cost / vs-Claude panel | yes | no |
+| Reasoning emitted as a structured `thinking` block | R1 sometimes leaks tool-call JSON inside `<think>` tags | a `scavenge` pass that pulls escaped tool calls back out |
+| Tool schemas validated strictly | DeepSeek silently drops deeply-nested object/array params | auto-flatten — nested params get rewritten to single-level prefixed names |
+| Tool-call args are well-formed JSON | DeepSeek occasionally produces `string="false"` and other malformed fragments | dedicated `ToolCallRepair` heals the common shapes before dispatch |
+| Reasoning depth tuned via system-level switches | V4 exposes a `reasoning_effort` knob (`max` / `high`) | `/effort` slash + `--effort` flag for cheap turns |
 
-On the same τ-bench-lite workload — 8 multi-turn tool-use tasks × 3
-repeats = 48 runs per side, live DeepSeek `deepseek-chat`, sole
-variable prefix stability:
+Cache stability isn't a feature you turn on; it's an invariant the loop is designed around. That's the entire reason Reasonix is DeepSeek-only.
 
-| metric | baseline (cache-hostile) | Reasonix | delta |
-|---|---:|---:|---:|
-| cache hit | 46.6% | **94.4%** | +47.7 pp |
-| cost / task | $0.002599 | $0.001579 | **−39%** |
-| pass rate | 96% (23/24) | **100% (24/24)** | — |

-**Reproduce without spending an API credit:**

-```bash
-git clone https://github.com/esengine/reasonix.git && cd reasonix && npm install
-npx reasonix replay benchmarks/tau-bench/transcripts/t01_address_happy.reasonix.r1.jsonl

-  benchmarks/tau-bench/transcripts/t01_address_happy.reasonix.r1.jsonl
-```
+## What's in the box
 
-The committed JSONL transcripts carry per-turn `usage`, `cost`, and
-`prefixHash`. Reasonix's prefix hash stays byte-stable across every
-model call; baseline's churns on every turn. The cache delta is
-*mechanically* attributable to log stability, not to a different
-system prompt.

 ## Non-goals
 
-- **Multi-agent orchestration / sub-agents** (use LangGraph).
-- **Workflow DSL / DAG scheduler / parallel-branch engine** — skills
-  are prose; the model sequences via the normal tool-use loop.
-  Keeps single-loop + append-only + cache-first invariants intact.
-- **Multi-provider abstraction** (use LiteLLM). Reasonix is
-  DeepSeek-only on purpose — every pillar (cache-first loop, R1
-  harvesting, tool-call repair) is tuned against DeepSeek-specific
-  behavior and economics. Coupling to one backend is the feature.
-- **RAG / vector stores** (use LlamaIndex).
-- **Web UI / SaaS.**
-
-Reasonix does DeepSeek, deeply.

-## Development
-
-```bash
-git clone https://github.com/esengine/reasonix.git
-cd reasonix
-npm install
-npm run dev code        # run CLI from source via tsx
-npm run build           # tsup to dist/
-npm test                # vitest (648 tests)
-npm run lint            # biome
-npm run typecheck       # tsc --noEmit
-```
+- **Multi-provider flexibility.** DeepSeek-only on purpose — every layer is tuned around DeepSeek's specific cache mechanic and pricing. Coupling to one backend is the feature.
+- **IDE integration.** Terminal-first; the diff lives in `git diff`, the file tree in `ls`. The dashboard is a companion, not a Cursor replacement.
+- **Hardest-leaderboard reasoning.** Claude Opus still wins some benchmarks. DeepSeek V4 is competitive on coding; if your work is "solve this PhD proof" rather than "fix this auth bug," start with Claude.
+- **Air-gapped / fully-free.** Reasonix needs a paid DeepSeek API key. For air-gapped or zero-cost runs see Aider + Ollama or [Continue](https://continue.dev).

+数据来自 `benchmarks/tau-bench-lite`（8 个多轮任务 × 3 次重放，真实 `deepseek-chat`）。[完整 transcript →](./benchmarks/)
+
+<details>
+<summary><strong>为什么只支持 DeepSeek？— 缓存经济学</strong></summary>
+
+便宜的 token 只是故事的一半。DeepSeek 的前缀缓存是**字节稳定**的：缓存指纹从 prompt 第 0 字节开始算。Reasonix 整个循环都围绕这一点设计——只追加、不重排、不做基于标记的 compaction，所以缓存前缀能跨过每一次工具调用存活下来。
+
+对比一下：Claude Code 是围绕 Anthropic 的 `cache_control` 标记构建的（完全不同的机制）。把 Claude Code 指向 DeepSeek 的 Anthropic 兼容端点，能拿到便宜的 token，但缓存命中没了——标记被忽略，底下的前缀本来就不字节稳定。通用后端工具（Aider / Cline / Continue）从另一个方向撞上同一堵墙：它们的 compaction 模式会破坏字节稳定。
+
+按 DeepSeek 的定价 —— $0.07/Mtok 未命中、$0.014/Mtok 命中 —— **50% 命中和 94% 命中之间的差距，光是输入成本就大约 2.5 倍。** 同模型、同 API；变的只是循环本身的不变量。
+
+通用循环漏掉的几个 DeepSeek 专属修复：
+
+| 通用循环假设的 | DeepSeek 实际表现 | Reasonix 的处理 |
+|---|---|---|
+| reasoning 在结构化的 `thinking` 块里 | R1 偶尔把 tool-call JSON 漏在 `<think>` 标签里 | 一个 `scavenge` pass 把逃逸的 tool call 拉回来 |
+| 工具 schema 严格校验 | DeepSeek 会静默丢掉深层嵌套的 object/array 参数 | 自动 flatten——嵌套参数被改写成单层带前缀的名字 |
+| tool-call 参数是合法 JSON | DeepSeek 偶尔吐 `string="false"` 之类的破碎片段 | 专门的 `ToolCallRepair` 在 dispatch 前把常见形状修好 |
+| reasoning 深度靠系统级开关调 | V4 暴露了 `reasoning_effort` 旋钮（`max` / `high`） | `/effort` 斜杠 + `--effort` flag，便宜回合可以降档 |
+
+缓存稳定不是个开关，是循环要围绕设计的不变量。这就是 Reasonix 只支持 DeepSeek 的根本原因。

+## 不做的事
+
+- **多供应商灵活性。** 故意只做 DeepSeek —— 每一层都为 DeepSeek 特定的缓存机制和定价调过。绑死一个后端是 feature，不是要克服的限制。
+- **IDE 集成。** 终端优先；diff 在 `git diff`，文件树在 `ls`。仪表盘是 TUI 的伴生，不是 Cursor 的替代。
+- **追最难的 reasoning 榜单。** Claude Opus 在某些榜单上还是赢家。DeepSeek V4 在编程任务上有竞争力；如果你的工作是"解一个 PhD 级证明"而不是"修个 auth bug"，先用 Claude。
+- **完全离线 / 永远免费。** Reasonix 需要付费的 DeepSeek API Key。要离线 / 零成本，看 Aider + Ollama 或 [Continue](https://continue.dev)。

+## Stack
+
+- **Language** — TS 5.6+, ES2022, ESM (`"type": "module"`)
+- **CLI** — Commander.js + Ink 5 (React 18) TUI
+- **Test** — Vitest 2.x
+- **Lint / Format** — Biome 1.9 (2-space, double quotes, semicolons always, 100 width)
+- **Build** — tsup (bundle), `tsx` (dev runner)
+- **MCP** — stdio + SSE transports, in-process fake in tests
+
+## Layout
+
+| Path | What |
+|---|---|
+| `src/cli/` | CLI entry + commands (`chat.tsx`, `code.tsx`, `diff.ts`, etc.) + Ink TUI in `ui/` |
+| `src/tools/` | Tool defs (filesystem, shell, MCP, plan, subagent, web, workspace) |
+| `src/mcp/` | MCP client, transports (stdio, SSE), registry, spec |
+| `src/repair/` | Tool-call repair pipeline (flatten, scavenge, storm, truncation) |
+| `src/index/` | Semantic vector index |
+| `src/code/` | SEARCH/REPLACE edit-block parser + apply gate |
+| `src/core/` | Event-log kernel — `events.ts` (Event union), `reducers.ts` (pure projections), `eventize.ts` |
+| `src/ports/` | Port interfaces — ModelClient, ToolHost, EventSink, MemoryStore, HookRunner, CheckpointStore |
+| `src/adapters/` | Concrete adapters for the ports (e.g. `event-sink-jsonl.ts`, `event-source-jsonl.ts`) |
+| `src/frame/` | Frame compiler (cell grid → ANSI) used by the TUI log renderer |
+| `src/memory/` | Project / session / user / runtime memory stores |
+| `src/transcript/` | Transcript log (write), diff, replay |
+| `src/telemetry/` | Usage records + cross-session stats |
+| `src/server/` | Dashboard HTTP server + REST API |
+| `tests/` | Vitest tests, flat `*.test.ts` |
+| `examples/` | `basic-chat.ts`, `mcp-server-demo.ts`, etc. |
+| `benchmarks/` | Harvest + tau-bench harnesses |
+| `dashboard/` | Compiled dashboard SPA assets |
+| `data/` | Tokenizer data (`deepseek-tokenizer.json.gz`) |
+| `dist/` | Build output — **do not edit** |

+
+## Commands
+
+```sh
+npm run build       # tsup → dist/
+npm run dev         # tsx src/cli/index.ts
+npm run chat        # tsx src/cli/index.ts chat
+npm run test        # vitest run
+npm run test:watch  # vitest
+npm run lint        # biome check src tests
+npm run lint:fix    # biome check --write src tests
+npm run format      # biome format --write src tests
+npm run typecheck   # tsc --noEmit
+```
+
+`prepublishOnly`: lint → typecheck → test → build.
+
+## Conventions
+
+- **Imports** — explicit `import type` for type-only imports (Biome `useImportType: warn`). Direct relative imports within project, no barrel re-exports.
+- **Exports** — named exports only; no `export default`. Entry: `src/index.ts`.
+- **Tests** — vitest `describe`/`it`/`expect`, no globals. Naming: `<module>.test.ts` flat in `tests/`.
+- **JSX** — `.tsx` for Ink components. `jsx: "react"` in tsconfig.
+- **TypeScript** — `strict`, `noUncheckedIndexedAccess`, `noImplicitOverride`. Tools accept `ToolCallContext` (abort signal).
+- **MCP** — All transports implement `McpTransport` interface. Tools registered via registry at startup.
+- **Changelog** — Keep a Changelog format. Semver.
+
+## Watch out for
+
+- **This IS Reasonix** — edits to `src/loop.ts`, `src/repair/`, `src/tools/`, `src/mcp/` affect every session. Test before publishing.
+- **SEARCH must match byte-for-byte** — the edit-gate in `src/code/edit-blocks.ts` enforces exact match. Trailing whitespace or wrong indent = mismatch.
+- **`dist/`** is generated by `tsup`. Never hand-edit.
+- **`.reasonix/semantic/`** is auto-generated vector index. Never hand-edit.
+- **`sessions/` and `.reasonix/sessions/`** are user-private, git-ignored (per `.gitignore`).

+# Security Policy
+
+If you find a security issue in Reasonix, please report it privately rather than opening a public issue or discussion thread.
+
+## How to report
+
+Email <359807859@qq.com> with:
+
+- a clear description of the issue
+- steps that reproduce it (a minimal repro is fine)
+- the version (`reasonix --version`) and platform you observed it on
+
+You'll get an acknowledgement within a few days, and a fix or mitigation as soon as the maintainer can land it. If you'd like attribution in the release notes when the fix ships, say so in your report — the default is a quiet patch.
+
+## Supported versions
+
+Only the latest published minor of `reasonix` on npm is actively maintained. If you're on something older, please reproduce on the latest before reporting.
+
+## Scope
+
+**In scope:**
+
+- The published `reasonix` npm package and its CLI / TUI
+- The dashboard SPA shipped under `dashboard/` and the local HTTP server that serves it
+- The shell sandbox, edit gate, and tool dispatcher in `src/`
+
+**Out of scope:**
+
+- Third-party MCP servers attached via `--mcp` (report to those projects)
+- Misconfiguration of the user's own DeepSeek API key, environment, or shell profile
+- Vulnerabilities in upstream Node.js or in the DeepSeek API itself
+- Denial-of-service via deliberately oversized prompts or tool inputs (Reasonix is a single-user CLI; there's no multi-tenant boundary to defend)
+
+## Hardening notes
+
+A few practical reminders for users running Reasonix:
+
+- API keys live in `~/.reasonix/config.json`. Treat that file like any other credential store.
+- `run_command` and the `!` shell shortcut respect a permission allowlist; the safe default is `ask` on anything not pre-approved. Don't set `editMode: yolo` on machines that hold secrets you'd regret leaking.
+- Hooks (`PreToolUse`, etc.) execute arbitrary shell scripts the user has configured. Audit `.reasonix/settings.json` before running Reasonix in a directory you didn't author.

+
+Live `deepseek-chat` (DeepSeek prefix cache enabled by default).
+System prompt: 1546 chars (~390 tokens). 5 turns each with a small
+user message; tool-set varies between turns to simulate the drift
+shapes a `/mcp reconnect <name>` would emit.
+
+## Run

+5 · drift: EDITED desc (toolset A')          761     640     121   84.1%     791
+```
+
+(Turn 1's "cold" is misleading — the prefix had been seen by the
+remote cache from an earlier run within the cache TTL.)
+
+## Findings
+
+DeepSeek's prefix cache works at chunk granularity (consistent with
+publicly documented ~128-token chunks). Three concrete lessons:
+
+1. **Append-only drift is nearly free.** Turn 3 adds one tool *at the
+   end* of the tool list — every cache chunk before the new tool
+   stays valid, only the appended bytes miss. Net: 94.8% hit, even
+   higher than the no-drift baseline (because the system prompt +
+   whole toolset-A is still cached, and the appended chunk is now
+   cached too).
+2. **Mid-stream drift loses everything past the divergence.** Turn 5
+   edits a description on the *first* tool, so divergence falls
+   inside the tools block early. Hit drops to 84.1% — still high
+   here only because the system prompt occupies enough chunks before
+   the divergence point.
+3. **Position of the drift dominates the cost.** A trailing addition
+   is essentially zero. An edit near the start of tools is more
+   expensive. An edit in the system prompt itself (not tested) would
+   wipe the cache to zero — expected, but irrelevant for reconnect
+   since we don't change the system prompt on reconnect.
+
+## Implication for RFC #110
+
+The "any drift = full cache miss" framing in the RFC body is too
+pessimistic. The real cost of accepting a drifted reconnect depends
+on *where* the drift lands:
+
+- Server adds a new tool (most common reconnect drift) → trivial
+  cost, accept silently.
+- Server changes an existing tool's schema or description → bounded
+  cost depending on position, surface a one-line warning.
+- Server completely reorders or replaces the tool list → effectively
+  full miss, refuse or require `--force`.
+
+This nudges the design call away from blanket "strict default"
+toward a **graduated permissive** policy: accept appends silently,
+warn on mid-stream edits, refuse on whole-list reorders or removals.
+
+The strict approach can still be the explicit `--strict` flag for
+users who need every byte of cache (e.g. high-volume scripted runs).

+# Exp 1 — cache-hit cost analysis
+
+**Result: PASS.** Augmenting `edit_file` tool_results with an `[edit_claim]` + `[test_run]` footer does **not** reduce cache hit. In a controlled side-by-side, the augmented variant cache-hit at **93.6%** vs the baseline's **83.5%** on the same hot turn — a **+10pt improvement**, not a regression.
+
+This makes sense once you reason about where the new tokens land: they sit *inside the prefix*, not *in the tail*. On every subsequent turn they cache-hit. The non-cacheable tail (the new user message) is the same size in both variants, so growing the prefix grows the cache-hit ratio.
+
+## Method
+
+`benchmarks/spike-tdd-kernel/cost.mjs`. Two synthetic 4-turn agent transcripts, identical except that variant B's `edit_file` tool_result carries the RFC's proposed footer:
+
+```
+[test_run] test_id="…" status="pass" duration_ms=1873 command="npx vitest …"
+[edit_claim] test_id="…" edit_target="src/util/slugify.ts" satisfied=true
+```
+
+For each variant, three calls in sequence on `deepseek-chat`:
+1. **warmup** — seeds the prefix into DeepSeek's cache.
+2. **hot** — same prefix + a different small tail, measures steady-state cache hit.
+3. **hot2** — repeat to confirm stability.
+
+Cache hit ratio = `prompt_cache_hit_tokens / (hit + miss)` from the `usage` object.
+
+Raw runs in `cost-results.json`.
+
+## Numbers
+
+```
+                     prompt   hit   miss   ratio   wall
+A_baseline.warmup     464      0    464    0.0%    835ms

+A_baseline.hot2       460    384     76   83.5%   2792ms
+
+B_augmented.warmup    551    384    167   69.7%    575ms
+B_augmented.hot       547    512     35   93.6%   2065ms
+B_augmented.hot2      547    512     35   93.6%   1959ms
+```
+
+`B_augmented.warmup` already shows 69.7% because A's system prompt is in cache from prior calls — same byte-stable prefix region.
+
+## Why B has a *better* ratio than A
+
+The augmentation adds ~87 tokens to the prefix (the `[edit_claim]`/`[test_run]` footer). On the hot turn:
+
+- A: prefix-cacheable = 384 tok, tail = 76 tok → 384 / (384+76) = 83.5%
+- B: prefix-cacheable = 512 tok, tail = 35 tok → 512 / (512+35) = 93.6%
+
+Both have the same kind of tail (a new user message). B's tail is smaller because the model emitted a slightly different response continuation seed; nonetheless, the structural point holds: **augmenting tool_results moves bytes from "uncached" (this-turn-only) to "cached" (re-used by every subsequent turn)**.
+
+In real Reasonix sessions with multi-thousand-token histories, the absolute cache-hit ratio is dominated by history size; the marginal effect of an extra ~80 tokens per edit is to *raise* it slightly, not lower it.
+
+## Pass criterion (revised)
+
+The original RFC threshold of "≥92% absolute" doesn't apply cleanly to this synthetic harness — the transcript is only ~460 tokens, far smaller than a typical Reasonix session, which inflates the tail's relative weight.
+
+The substantive criterion is **no degradation**:
+
+> augmentation must not reduce cache hit by more than 2pts vs baseline
+
+Observed: **+10pt improvement**. Passes trivially.
+
+## Implications for the RFC
+
+1. **Cost story is intact.** The "kept cache hit ≥94%" claim in the README is unaffected. Augmenting tool_results is cache-positive, not cache-negative.
+
+2. **Footer placement matters.** Two safe places:
+   - **Append to `edit_file` tool_result** (this experiment). Cache-friendly.
+   - **Insert as a separate synthetic `tool` message between turns** (would also be cache-friendly *if* always at the same position).
+
+   Avoid: rewriting an old tool_result mid-stream, which would invalidate cache from that point onward. The `AppendOnlyLog` invariant in `src/loop.ts` already prevents this.
+
+3. **Footer format should be deterministic.** No timestamps that change per cache-hit attempt; no run-relative durations that vary; no random IDs. The fields chosen (`test_id`, `status`, `duration_ms`, `command`) are all deterministic at write time and frozen thereafter — same bytes, same cache.
+
+4. **Token cost is real but small.** ~80 prompt tokens per edit on subsequent turns. At v4-flash pricing that's negligible. The model also uses ~20 completion tokens to emit `edit_claim`. Total marginal cost per edit: <$0.0001.
+
+## Decision
+
+Greenlight Exp 1. **All four spike experiments pass.** Ready to comment "spike green" on #25 and start a 48h FCP.

+# Exp 4 — `vitest -t` latency on this repo
+
+**Result: PASS.** Median 1.9s, p95 ~5.0s, max 5.1s. Both pass thresholds met (median ≤3s, p95 ≤6s).
+
+## Method
+
+`benchmarks/spike-tdd-kernel/bench-latency.mjs` runs `npx vitest --run <file> -t "<name>"` against 10 sampled test/name pairs across 9 different test files, twice each (cold = first invocation, warm = immediate repeat). Each invocation is a fresh `npx` subprocess. Wall-clock measured around `spawnSync`. Raw data in `latency.json`.
+
+## Numbers
+
+| | median | p95 | max |
+|---|---|---|---|
+| cold | 1900 ms | 4731 ms | 4815 ms |
+| warm | 1888 ms | 4972 ms | 5075 ms |
+
+All 20 invocations exited 0.
+
+## Findings
+
+1. **Cold ≈ warm.** Each `npx vitest --run` boots a fresh worker, so there is no meaningful warm-up benefit. The ~1.9s floor is overwhelmingly framework startup (vite + vitest + tsx transform), not test work. The two slowest tests (`edit-blocks`, `bang`) hit ~5s on both cold and warm, indicating per-test overhead specifically — likely module graph size, not test logic.

+2. **Implication for kernel design.** Running N separate `vitest --run -t <id_n>` is N × ~2s. **Batching multiple `test_id`s in one invocation** (`vitest --run -t a -t b -t c`) almost certainly amortises the boot cost. RFC's "auto-run after each edit" should bundle test_ids when an edit pass writes more than one — and a bulk-edit batch should only fire one vitest invocation at the end.
+
+3. **Threshold headroom is thin on slow tests.** A test that already takes 5s warm leaves ~1s for kernel overhead before the user starts noticing. Per-edit auto-run is fine; per-keystroke would not be.
+
+## Decision
+
+Greenlight the latency assumption in the RFC. Update RFC §"Cost analysis" to reflect:
+- "+1 test run per edit" → "+1 vitest invocation per edit batch"
+- Add note that the kernel should coalesce edits within one model turn into a single `vitest -t a -t b …` call.
+
+## Sample tests used
+
+- `checkpoints.test.ts` (×2)
+- `compact-tokens.test.ts` (×2)
+- `diff.test.ts`, `edit-blocks.test.ts`, `event-replay.test.ts`, `event-sink-jsonl.test.ts`, `at-mentions.test.ts`, `bang.test.ts`

+# Exp 3 — DeepSeek V4 TDD reliability
+
+**Result: PASS.** 8/10 strict, 10/10 once an over-strict scoring bug is corrected. Both thresholds (≥70% strict, ≥50% before redesign) cleared comfortably.
+
+## Method
+
+`benchmarks/spike-tdd-kernel/tdd-eval.mjs` runs 10 prompts across 5 easy / 3 medium / 2 hard difficulty levels against `deepseek-v4-flash` at temperature 0. The system message demands a single failing vitest file with no implementation. Each response is scored on:
+
+- **shape**: contains `describe`, `it`/`test`, and at least one `import`
+- **importsTarget**: imports the module-under-test by some path
+- **implLeak**: whether the test file defines the function-under-test (regression — the model was supposed to write only the test)
+- **stableNames**: every `it()`/`test()` title is a literal string with no template / `Date.now()` / `Math.random()`
+- **tsOk**: passes `tsc --noEmit` after replacing the target import with `vitest` (purely a syntax check)
+
+Pass-all requires all five.
+
+Raw runs in `tdd-eval.json` (~5 KB).
+
+## Numbers
+
+```
+e1 (easy)   shape=Y import=N* leak=N names=Y ts=Y → fail*
+e2 (easy)   shape=Y import=Y  leak=N names=Y ts=Y → PASS

+h2 (hard)   shape=Y import=Y  leak=N names=Y ts=Y → PASS
+
+8/10 = 80% strict
+10/10 = 100% once import-path scoring is corrected (see below)
+tokens: 2246 prompt + 5732 completion (≈ $0.001 total)
+```
+
+## The two "failures" are scoring bugs
+
+The strict regex required imports of the form `from ".../src/util/slugify"`. The two failing prompts produced these imports:
+
+```
+e1: import { slugify } from '../slugify';                      // assumes test is co-located
+h1: import { extractTestId } from './src/repair/test-id';      // assumes test is project-root-relative
+```
+
+Both **import the correct symbol from a path that points at the right module**. They differ only in *where the test file is assumed to live*, which is a question the prompt didn't answer. In the real flow, the model also picks the test file location, so the import is self-consistent. These should count as PASS.
+
+## What the model got right consistently
+
+- 10/10 imported `vitest` correctly.
+- 10/10 wrote one `describe` + multiple `it` blocks, no nested test stubs.
+- 10/10 had stable, literal `it()` names — no parametrise leaks, no clocks, no RNG.
+- 10/10 did NOT define the target function in the test file (no impl leak).
+- 10/10 passed `tsc --noEmit` syntax check.
+- Median latency 8.2s, p95 14s. Slower than expected for `v4-flash`, but acceptable given output size (~500 tokens / response).
+
+## What the model got "wrong"
+
+- Underspec: when given no test file location, it guesses one. Reasonable behavior, but the kernel will need to specify (or accept the model's choice and write the file there).
+- Hard prompts (h1, h2) took 11–14s vs. easy ~5s. Acceptable.
+
+## Implications for the RFC
+
+1. **Greenfield flow is viable.** The model can reliably author a failing test first when explicitly told to. Open question §1 in RFC #25 can be closed: a structured `author_failing_test` tool is **not** required — a clear system message suffices.
+
+2. **The kernel should specify (or extract) the target test file path.** When `submit_plan` includes a step with `test_id`, it should also include `test_file_path`. The dispatcher uses that to:
+   - know where to write the failing test
+   - resolve the relative import path the model emits
+   - compute the eventual `<rel-path>::<fullName>` id
+
+3. **Strip-and-validate the model output.** Even though shape passed 10/10, the kernel should still:
+   - strip markdown fences (the model occasionally wraps in `\`\`\`ts ... \`\`\`` — none of the 10 did, but be defensive)
+   - reject any file that defines the target symbol (impl leak) before running it
+   - require the test fail with `Error: Cannot find module …` or a real assertion failure (not a SyntaxError)
+
+4. **Latency.** ~8s median per failing-test authoring. For a per-feature TDD step, that's fine. Combined with Exp 4's ~2s vitest run, the red event lands ≤12s after the user kicks off a feature — acceptable UX.
+
+## Decision
+
+Greenlight Exp 3. Combined with Exp 2 + Exp 4, the proposal's three feasibility risks are resolved. **Move to Exp 1.**

+# Exp 2 — `test_id` stability spec
+
+**Result: PASS (with hybrid).** Adopt vitest-native id (`<rel-path>::<fullName>`) as the default, with an optional annotation override for users who care about rename stability.
+
+## Schemes evaluated
+
+### A. vitest-native — `<relative-path>::<fullName>`
+
+Example: `tests/bang.test.ts::detectBangCommand returns the command body for a \`!\`-prefixed input`
+
+Verified against the JSON reporter (`npx vitest --reporter=json`); `fullName` is the documented `describe` chain joined with the leaf title and is what `-t "<fullName>"` matches against.
+
+| event | stable? |
+|---|---|
+| edit test **body** (logic, asserts) | yes |
+| rename `it()` title | **no** — id changes |
+| rename outer `describe()` | **no** — id changes |
+| move file | **no** — path changes |
+| reorder `describe` blocks | yes |
+| `it.each` parametrise: add row | yes for existing rows; new id appears |
+| `it.each` parametrise: change a row's args | id changes for that case |
+
+Critical failures: 3 (rename it / rename describe / move file).
+
+### B. content hash — sha256 of test body
+
+| event | stable? |
+|---|---|
+| edit test body | **no** — id changes on any whitespace edit |
+| rename it/describe | yes |
+| move file | yes |
+| parametrise | yes (body unchanged) |
+
+Critical failure: 1, but it's the worst possible one. Tests evolve while red — adding asserts, narrowing scope. A scheme that invalidates `test_id` on every body edit makes `edit_claim` impossible to track across the red→green journey. **Reject.**
+
+### C. user annotation — `// @reasonix-test-id: foo`
+
+| event | stable? |
+|---|---|
+| edit body / rename / move | yes |
+| parametrise | ambiguous — one id, N runs |
+| greenfield | requires model to invent + uniqueness-check |
+| existing 96 test files | zero have it; brownfield bootstrap is awkward |
+
+Critical failures: 2 (parametrise ambiguity, brownfield bootstrap). Strong on rename, weak on adoption.
+
+## Decision: hybrid (A as default, C as opt-in override)
+
+Default `test_id` = `<rel-path>::<fullName>`.
+If the test source contains `// @reasonix-test-id: <slug>` directly above the `it(`/`test(`, that slug overrides the default.
+
+```ts
+// @reasonix-test-id: bang.parses-leading-bang
+it('returns the command body for a `!`-prefixed input', () => { … });
+```
+
+This handles the failure modes of A:
+- **Rename it/describe**: a user who anticipates renames adds the annotation once. Without it, kernel treats rename as a new test (correct — the old red is gone, so should be the old claim).
+- **Move file**: same — annotation makes the id survive moves.
+- **Brownfield**: zero churn for existing 96 files; they use the default.
+- **Greenfield**: model uses the default unless the user requests stability. `reasonix doctor` could surface a warning when a `test_id` would be lost.
+
+### How the dispatcher resolves it
+
+When extracting `test_id` from a `test_run` event, the kernel:
+1. Parses `--reporter=json` output → `{file, fullName}`.
+2. Reads the test source (already in workspace).
+3. If an annotation comment within 3 lines above the matched `it(` exists, use the slug.
+4. Else use `<rel-path>::<fullName>`.
+
+This is deterministic and replayable from `events.jsonl` alone (the source at the time of the event is captured by the workspace snapshot).
+
+## Implications for the RFC
+
+Update RFC §"New event types":
+
+```ts
+type TestRunEvent = {
+  type: 'test_run';
+  test_id: string;           // <rel-path>::<fullName>  OR  user annotation slug
+  test_id_source: 'native' | 'annotation';   // for debugging / migration
+  status: 'pass' | 'fail';
+  command: string;
+  duration_ms: number;
+  ts: number;
+};
+```
+
+Add §"`test_id` resolution" subsection citing this spec.
+
+## Out of scope (defer)
+
+- Cross-runner support (jest, mocha). Reasonix workspaces today are predominantly vitest; ship vitest-only first.
+- Refactor-safe id (e.g., AST-based fingerprint resilient to whitespace + rename). Possible v2.

+# Staged work estimate — kernel red-green (RFC #25)
+
+> Local-only estimate, paired with `tracking-issue-draft.md`. Numbers are wall-clock for one focused day, not "ideal" hours.
+
+## Total
+
+~4–5 days of actual coding across all three stages. Then ~2 minor releases of soak before flipping default-on.
+
+| Stage | Code (LoC) | Tests (LoC) | Wall time | Risk |
+|---|---|---|---|---|
+| 1. events + writer | ~300 | ~150 | 0.5 day | low |
+| 2. dispatcher gate | ~600 | ~400 | 2–3 days | **high** |
+| 3. plan + UI | ~250 | ~120 | 1 day | medium |
+
+## Stage 1 — events + writer (0.5 day)
+
+Almost entirely additive, no behavior change.
+
+**Changes:**
+- `src/core/events.ts:190` — extend `Event` union with `TestRunEvent` + `EditClaimEvent`.
+- `src/core/test-id.ts` (new, ~50 LoC) — `extractTestId(file, fullName, source)` per `test-id-spec.md`.
+- `src/core/reducers/red-green.ts` (new, ~30 LoC) — `pairRedGreen(events)` reducer.
+- `src/cli/commands/events.ts` — add `red-green` subcommand listing pairs.
+- `src/adapters/event-sink-jsonl.ts` — already generic over `Event`, no edits required.
+
+**Tests:**
+- Round-trip: append a `test_run` event, replay through reducer.
+- `extractTestId` matrix: 8 cases (rename, move, parametrise, annotation override, etc.).
+
+**Risk:** low. Pattern matches existing event additions in v0.14.
+
+## Stage 2 — dispatcher gate (2–3 days, **the load-bearing one**)
+
+This is where most of the actual integration risk lives.
+
+**Changes:**
+- `src/tools/filesystem.ts:518` — `edit_file` registration wraps in a gate. When `REASONIX_STRICT_TDD=1`:
+  1. Look up most recent `test_run` for `test_id` from in-memory event list (cheaper than re-reading jsonl).
+  2. Verify a matching `edit_claim` followed it.
+  3. On dispatch refusal, throw a structured error the model can read.
+- `src/loop.ts` — per-turn coalescing buffer:
+  - When `edit_file` succeeds, push `{test_id, test_file_path}` to a turn-scoped Set.
+  - At end-of-turn (just before the next assistant call), spawn one `vitest --run -t a -t b -t c` covering all collected ids.
+  - Parse `--reporter=json` output, emit one `test_run` event per id.
+  - On any red, revert the offending edits via the existing checkpoint mechanism (`src/checkpoints.ts`), emit a `repair` event so the storm-breaker engages.
+- `/refactor` mode — session flag in `LoopState`. When true, gate is bypassed; on session exit, run `npm run verify` (or `reasonix.config.ts`'s `verify_command`).
+- `reasonix.config.ts` schema — add `verify_command` and `test_command_for(test_id)`.
+
+**Tests:**
+- Integration on a synthetic session fixture: green path, red revert, multi-edit batch, `/refactor` bypass, edit before any test_id (refused).
+- Mock vitest spawner so tests don't depend on actual vitest runs.
+
+**Risk: high.** Specific concerns:
+- **Loop coordination.** End-of-turn flush has to play nice with: abort controller (`_turnAbort`), /pro escalation (mid-turn model swap), storm-breaker (`src/repair/storm.ts`), thinking-mode round-trip (reasoning_content preservation). Any one of these can desynchronise the buffer.
+- **Vitest spawn hang.** Need timeout + kill + emit a `test_run` event with `status='fail'` and a tagged failure reason. Otherwise a stuck test hangs the whole agent.
+- **Cross-platform paths.** Vitest's `fullName` should be POSIX-normalised before becoming part of `test_id`; spike runs were on Windows but didn't stress this.
+- **Revert semantics.** If batch had 3 edits and 1 went red, only that file reverts; others stay. Existing `Checkpoint` is per-file, but the index (`src/checkpoints.ts`) needs a partial-restore code path.
+
+**Mitigation:** land stage 2 in two PRs — first the gate + buffer behind a new flag (no auto-run), then the auto-run + revert. Validates the synchronisation before adding the spawner.
+
+## Stage 3 — plan + UI (1 day)
+
+**Changes:**
+- `src/tools/plan-types.ts:3` — `PlanStep` gains `test_id?` + `test_file_path?`.
+- `src/tools/plan-core.ts` — `submit_plan` validation: any step with `test_id` must have `test_file_path`.
+- `src/cli/commands/doctor.ts` — warn when plan has `test_id` but missing `test_file_path`; warn on first session in an untested codebase, suggest `/refactor` default.
+- TUI plan card — render red/green dots per step (need to inspect `src/cli/ui/cards/PlanCard*` to see how steps render today).
+
+**Tests:**
+- Plan validation: rejects step with `test_id` missing `test_file_path`.
+- Doctor output: snapshot of warning lines.
+- TUI snapshot for a 3-step plan with mixed red/green/pending dots.
+
+**Risk: medium.** TUI rendering is the unknown — depends on whether the current plan card has slots for status badges, or if the layout needs widening.
+
+## Default-on rollout (calendar, not work)
+
+- After stage 3 lands: minor release with flag *off* by default.
+- Two minor releases of soak — collect any hangs / false-refusals via telemetry, fix in patches.
+- Flip default-on; keep `REASONIX_STRICT_TDD=0` opt-out for two more minor releases.
+
+## Cross-cutting risks not pinned to a stage
+
+1. **Untested codebases.** `reasonix doctor` should detect (no `tests/` dir, no `vitest.config.*`) and refuse to enable strict mode at all on first run. Otherwise the flag is unusable.
+2. **Greenfield test-file location.** Spike Exp 3 showed the model picks reasonable but inconsistent paths when none is specified. The plan-step `test_file_path` field is the fix, but a user editing a single file with no plan still has the gap. Stage 2 should refuse `edit_file` when strict + no `test_file_path` is in scope.
+3. **MCP-served edit tools.** Reasonix supports MCP-hosted tools (`src/mcp.ts`). If an MCP server exposes its own write/edit tool, the kernel gate doesn't apply. Stage 2 should at minimum log a warning; longer-term, MCP write tools could opt into the same gate via a hook.
