feat: version display in TUI header + reasonix update self-upgrade (0.4.22)

Two small quality-of-life additions. The stats panel now carries the running version (`Reasonix v0.4.22 · model …`) so users can tell at a glance whether they're on the latest build. A 24-hour background check against the npm registry surfaces a yellow `update: X.Y.Z` nudge on the right side of the same row when a newer version has been published — 2s timeout, cache at `~/.reasonix/version-cache.json`, silent on failure. `reasonix update` is the command form: detects global install vs npx, spawns `npm install -g reasonix@latest` for the former or prints a cache-refresh hint for the latter. `--dry-run` prints the plan. Also fixes a drifted VERSION constant: `src/index.ts` hard-coded "0.4.20" while package.json was on 0.4.21. Now re-exports from `src/version.ts`, which walks up from import.meta.url to the manifest on first access. A regression test pins them together. New files: `src/version.ts`, `src/cli/commands/update.ts`, `tests/version.test.ts`, `tests/update-command.test.ts`. +24 tests (suite 648 → 672). Lint/typecheck/build clean.

-Delete this section if the PR touches nothing under `desktop/frontend-next/src`

-
- Screenshots, before and after: light and dark, a wide window and a phone-width one (about 390 px). Attach them to this description.
- Entries moved, hidden or removed: none / list each one.
- Hiding or removing a visible control needs a linked issue and a release-notes line naming it. Do not retire UI with `display: none !important` or a feature flag.
- If a row of `docs/STUDIO_PARITY.md` changes, update it here.
-
-## Issues
-
-<!--
-If this resolves a report, put `Fixes #123` on its own line — GitHub only
-auto-closes from a bare line, so `- Fixes #123` in a list does nothing and the
-report stays open. If it only relates to one, use `Refs #123` instead: the
-release workflow then asks that reporter to verify once the fix ships.
-->
-
-## Verification
-
-
-
-For a GSAP to WAAPI/CSS migration (or any cross-API replacement), document
-the source-to-target contract here: easing syntax, time units, callbacks,
-cancellation, reduced-motion behavior, and failure fallback. Verification must
-assert that the target API was actually called; a mock that silently skips it
-does not count.

-# Contributing to Reasonix
-
-Thank you for your interest in contributing to Reasonix! This guide covers
-everything you need to get started.
-
-## Prerequisites
-
- **Go 1.26+** — the version `go.mod` requires
- **Git** — for version control
- **Node.js 24+ and pnpm 10** (optional) — only if you work on Studio
-  (`desktop/`)
-
-## Getting started
-
-```bash
-git clone https://github.com/esengine/DeepSeek-Reasonix.git
-cd DeepSeek-Reasonix
-go build ./cmd/reasonix    # builds the CLI binary
-go test ./...              # runs the full test suite
-```
-
-## Project structure
-
-| Directory | Purpose |
-|-----------|---------|
-| `cmd/reasonix` | CLI entry point |
-| `internal/runtime/agent` | Agent loop, session, coordinator |
-| `internal/frontend/cli` | TUI, subcommands, setup wizard |
-| `internal/session/control` | Transport-agnostic controller |
-| `internal/contract/config` | TOML configuration loading |
-| `internal/tools/builtin` | Built-in tools (bash, read_file, …) |
-| `internal/contract/provider` | Model-backend abstraction |
-| `internal/model/openai` | OpenAI-compatible provider |
-| `internal/ext/plugin` | MCP client (stdio + HTTP) |
-| `internal/contract/event` | Typed event stream |
-| `internal/ext/hook` | Shell hooks (PreToolUse, …) |
-| `internal/state/memory` | REASONIX.md hierarchy + auto-memory |
-| `internal/ext/skill` | Skill discovery from Markdown |
-| `internal/safety/sandbox` | OS-level sandboxing |
-| `internal/frontend/serve` | HTTP/SSE server frontend |
-| `internal/state/checkpoint` | Snapshot-based rewind |
-| `desktop/` | Studio: the Electron shell, the SPA it serves (separate Go module) |
-| `docs/` | Engineering spec, migration guide |
-
-### Dependency direction
-
-```
-cli → {agent, plugin, config} → {tool, provider}
-```
-
-Built-in subpackages import their parent to self-register via `init()`.
-Parents never import children.
-
-## Development workflow
-
-### Building
-
-```bash
-make build          # go build ./...
-make test           # go test ./...
-make vet            # go vet ./...
-make fmt            # gofmt -w .
-make hooks          # install git hooks (pre-push: go vet)
-make cross          # cross-compile for all 6 targets
-```
-
-### Isolated development environment
-
-A source-built binary shares no on-disk state with a stable release when launched
-with `REASONIX_HOME` set. This gives each build its own self-contained directory
-tree — config, credentials, sessions, cache, skills, commands, hooks, and
-desktop tab state — so the two builds never interfere:
-
-**CLI**
-
-```bash
-REASONIX_HOME=/tmp/reasonix-dev go run ./cmd/reasonix
-# or after building:
-#   REASONIX_HOME=/tmp/reasonix-dev ./bin/reasonix
-```
-
-**Studio**
-
-```bash
-REASONIX_HOME=/tmp/reasonix-dev-isolated make studio
-```
-
-On Windows, use `$env:REASONIX_HOME` in PowerShell or `set REASONIX_HOME=` in
-Command Prompt; the binary extension is `.exe`.
-
-The directory is empty on first launch; the app behaves exactly like a fresh
-install. Every subsequent write — config saves, credential storage, session
-logs — stays under `REASONIX_HOME`. Legacy migration, OS-home convention
-directory scanning, and all other fallback paths are skipped so no production
-data leaks in or out.
-
-### Cache-first review gate
-
-Reasonix treats high prompt-cache hit rate as product behavior. Changes that
-touch provider-visible system prompt construction, memory prefix, output styles,
-skill index behavior, default tool surfaces, tool schemas, provider request
-serialization, compaction, or MCP/tool registration need explicit cache review.
-
-For these changes:
-
- Keep system prompt changes low-frequency and require explicit review.
- Say in the PR what the change does to the provider-visible prefix, and why
-  that cost is worth paying.
- Prefer focused guard tests near the changed surface; `scripts/cache-guard.sh`
-  remains the broader release-level cache-hit check.
-
-### Running tests
-
-```bash
-go test ./...                           # all tests
-go test ./internal/runtime/agent/ -v            # verbose, one package
-go test ./internal/tools/builtin/ -run TestGrep  # one test
-```
-
-`testenv.IsolateUserState` installs a disposable user home and config-edit lock
-scope. Default-path tests can clear `REASONIX_HOME` without losing the test
-registry, while explicitly isolated Reasonix homes retain their own locks.
-
-`REASONIX_TEST_HOME` carries the scope to helper subprocesses. A helper that
-skips the isolation guard must install the inherited home with
-`testscope.InstallHome` before running tests.
-
-The environment variable alone cannot activate a test scope. Production
-executables still use the OS account's home for shared config locks.
-
-The guard removes its scratch home on normal completion. Scratch homes are
-created under the original home, so an interrupted run can still leave
-`.reasonix-test-home-*` directories; this is separate from persistent
-config-edit locks in the real `.reasonix/locks` directory.
-
-### Code style
-
- `gofmt` is enforced by CI — format before committing
- Follow existing patterns: wrap errors with `fmt.Errorf("...: %w", err)`
- Library code never calls `os.Exit` or prints to stdout/stderr
- Only `cli/` and `main/` decide exit codes and user-facing messages
- Exported identifiers must have doc comments
-
-### Commit messages
-
-Follow [Conventional Commits](https://www.conventionalcommits.org/):
-
-```
-feat(glob): add ** recursive pattern support
-fix: replace silent error discards with structured logging
-test(event): add comprehensive unit tests for event package
-docs: add CONTRIBUTING.md
-ci: add golangci-lint and govulncheck
-```
-
-## Adding a new built-in tool
-
-1. Create `internal/tools/builtin/mytool.go`
-2. Implement the `tool.Tool` interface: `Name()`, `Description()`, `Schema()`, `ReadOnly()`, `Execute()`
-3. Register via `func init() { tool.RegisterBuiltin(myTool{}) }`
-4. Add tests in `internal/tools/builtin/builtin_test.go` or a separate `mytool_test.go`
-5. The tool is automatically available — `main` blank-imports `builtin`
-
-## Adding a new model provider
-
-(For MCP tool servers see `internal/ext/plugin` instead — that's a different layer.)
-
-1. Create `internal/contract/provider/myprovider/`
-2. Implement `provider.Provider`: `Name()`, `Stream()`
-3. Register via `func init() { provider.Register("mykind", New) }`
-4. The provider is available from config with `kind = "mykind"`
-
-## Adding i18n strings
-
-1. Add the field to `internal/base/i18n/i18n.go` (`Messages` struct)
-2. Add the value in `internal/base/i18n/messages_en.go` and `messages_zh.go`
-3. The `TestCatalogsComplete` test will fail if you miss a locale
-
-## Submitting changes
-
-Reasonix ships on two lines (see the
-[version roadmap](https://github.com/esengine/DeepSeek-Reasonix/discussions/10748)),
-and each takes different changes:
-
-| Line | Branch | Takes |
-| --- | --- | --- |
-| 2.x | `studio` | Features and fixes: active development |
-| 1.x | `main-v2` | Bug fixes, provider/API compatibility, release/updater, security, platform stability |
-
-A fix that matters on both lines lands on `main-v2` and is reviewed for
-porting to `studio`; do not open the same PR against both.
-
-1. Fork the repository
-2. Create a feature branch from the branch your change targets
-3. Make your changes with tests
-4. Ensure `go test ./...` passes
-5. Ensure `gofmt -l .` shows no changes
-6. Submit a pull request to that same branch
-
-## Pull request policy
-
-**Related changes.** If you have several related changes of one pattern, a
-tracking issue plus one pull request is easiest to review.
-
-**Issue first for features.** A change that adds behaviour rather than fixing a
-defect should link an issue the maintainers have agreed to before the work
-starts. A fix for a reproducible defect may open directly, with the failing test
-in the PR. Documentation-only and test-only PRs are reviewed at lower priority.
-
-**Review tiers.**
-
- Changes under the `sensitive:` paths declared in `REASONIX.md` get a full
-  review plus a security review, regardless of author.
- Every PR carries the four sections of the PR template: Cause, Blast radius,
-  Neighbouring behaviours tested, Why this layer.
- The new test must fail without the change.
- A UI change (`desktop/frontend-next/src` or the website pages) fills the
-  template's UI section: screenshots before and after, light and dark, wide
-  and phone width.
- The same section carries the line "Entries moved, hidden or removed".
- Hiding or removing a visible control needs a linked issue and a release-notes
-  line naming it, and updates `docs/STUDIO_PARITY.md` for a 1.x feature.
- Review holds these; no check reads them.
-
-**Transparency.** The PR template has an optional checkbox for disclosing AI
-assistance. It is for transparency only and does not change how a change is
-reviewed.
-
-## Reporting issues
-
-Open an issue on GitHub with:
- Which line (1.x or 2.x) and the exact version
- Steps to reproduce
- Expected vs actual behavior
- Go version and OS
- Relevant logs or error messages
-
-## License
-
-By contributing, you agree that your contributions will be licensed under the
-same license as the project.

-## What it is
-
-Reasonix is an open-source AI coding assistant. The program runs on your computer; the AI model is a service you configure, which receives what it reads. You describe a task in plain language; it reads code, edits files and runs commands and tests inside the project folder you choose, and shows you each step.
-
-You pick the model: a DeepSeek preset is built in, any OpenAI-compatible service is one config entry, and you pay the model provider directly.
-
-## What you get
-
- **Read, edit, run.** It reads code, edits files and runs tests and commands, all inside your project folder.
- **Permission levels.** Have it ask every time, or let everyday actions run on their own; your forbid rules always hold. To see the approach first, use plan mode: it starts work only once you approve.
- **Rewind.** A file is saved before it changes, so you can rewind by conversation turn without touching your git history. Only files its edit tools changed are covered, not what a shell command did.
-
-## 30-second start
-
-Download, add a model key, open a project. New here? Start with the Studio desktop app.
-
-1. Download and install the desktop app, Reasonix Studio, from the [releases page](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true).
-2. Open it and enter your model provider and key when asked.
-3. Open your project folder and write what you want, for example "add retry on failure to the http client".
-4. At the level you chose, it stops and asks before anything that needs your say-so. Allow it to continue, or refuse.
-
-Prefer a terminal? Download the `reasonix` command-line tool, run `reasonix setup` to pick a model, then run `reasonix`. See [Install](#install) and [Quick start](#quick-start).
-
-## Four ways to use it
-
- **Desktop app (Studio).** A graphical app; the best place to start.
- **Terminal.** A full-screen text interface; `reasonix run "task"` also works in scripts.
- **Browser.** `reasonix web` opens a web interface on your own machine.
- **Editor.** Install the extension in VS Code; other editors that support ACP (Agent Client Protocol, a common way for an editor to connect to an AI assistant) can connect to `reasonix acp`.
-
-All four are the same program underneath. What follows is for advanced users and contributors.
-
-## Use it from DeepSeek Harness
-
-DeepSeek Harness (`dsh`) can hand a task to Reasonix as a subagent over ACP. This repository publishes a plugin index for it:
-
-1. Run `reasonix setup` on the machine that runs `dsh`. In the DSH Web UI turn on Custom plugin markets (Plugins, More) and add this index in the Discover tab: `https://raw.githubusercontent.com/esengine/DeepSeek-Reasonix/studio/integrations/dsh-plugin/market-index.json`
-2. Install "Reasonix subagent" from it.
-3. Open the plugin's page and turn its switch on. While it is off the model has no `reasonix` tool and may run `reasonix -p` in its own shell, which looks like a delegation and is not one.
-
-Setup details, the permission policy and limits are in [Using Reasonix from DeepSeek Harness](./docs/DSH.md).
-
-## Versions
-
-Reasonix ships on two lines. See the [version roadmap announcement](https://github.com/esengine/DeepSeek-Reasonix/discussions/10748) for the reasoning behind the split.
-
-| Line | Branch | Status | Get it |
-| --- | --- | --- | --- |
-| **Reasonix 2.x** | `studio` (this branch) | Active development | [Studio releases](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true) |
-| **Reasonix 1.x** | [`main-v2`](https://github.com/esengine/DeepSeek-Reasonix/tree/main-v2) | Maintenance / stable | `npm i -g reasonix` · [desktop download](https://reasonix.io/?download=desktop#start) |
-
- **Want something stable?** Stay on 1.x. It keeps receiving bug fixes,
-  provider/API compatibility, updater and security fixes; its core architecture
-  is no longer being extended.
- **Want the new architecture?** Use 2.x Reasonix Studio. It is still moving
-  quickly; reports are welcome.
-
-Valuable fixes, tests and behaviour from 1.x are reviewed one by one and ported
-or reimplemented on 2.x where they fit the new architecture.
-
- [Moving from 1.x to 2.x](./docs/MIGRATING.md): what the two lines share, and
-  how to run both on one machine without losing sessions.
- [2.x roadmap](./docs/ROADMAP.md): what 2.x still has to deliver, how it ships,
-  and the decisions still open.
-
-## Features
-
-Technical highlights for advanced users.
-
- **Config-driven.** Providers, the agent, enabled tools, and plugins are all
-  declared in `reasonix.toml`. No hardcoded models.
- **Multi-model & composable.** DeepSeek ships as a preset; any
-  OpenAI-compatible endpoint is a config entry, not new code. Optionally run
-  two models together (executor + planner) in separate, cache-stable sessions.
- **Plugin-driven.** MCP servers contribute tools, prompts, and resources;
-  Extension Protocol v1 sidecars can also intercept runtime events, contribute
-  Providers and structured UI, and ship versioned plugin packages.
- **Cache-aware context maintenance.** Startup injects a small stable environment
-  summary, stale tool output is snipped/pruned before summary compaction, and the
-  built-in tool schema contract is documented for regression review.
- **Zero-friction distribution.** `CGO_ENABLED=0` single binary; cross-compile
-  to six targets with one command. The result is a fully self-contained static
-  binary — nothing to install on the target machine beyond the binary itself.
-
-## Install
-
-This branch is **Reasonix 2.x**. Its desktop app is Reasonix Studio; the CLI,
-Studio, and editor integrations all run the same local Reasonix engine.
-
-### Reasonix Studio (2.x)
-
-Download the package for your platform from the latest
-[Studio release](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true)
-(tagged `studio-v2.*`; candidates such as `-rc.N` are marked as
-pre-releases):
-
-| Platform | Package | Architecture |
-| --- | --- | --- |
-| macOS | `.dmg` or `.zip` | Apple Silicon (`arm64`) / Intel (`amd64`) |
-| Windows | Installer `-installer.exe` or portable `.zip` | x64 |
-| Linux | `.deb`, `.rpm`, or `.AppImage` (download only) | x64 (`amd64`) / ARM64 (`arm64`, aarch64) |
-
-Every package ships with a `.minisig` signature, and the release carries
-`SHA256SUMS`. Once installed, Studio updates itself in place.
-
-The same release also carries the 2.x `reasonix` CLI as archives for
-`darwin|linux|windows × amd64|arm64`.
-
-The Android build ships on that release as `ReasonixMobile-<version>.apk`
-(`arm64`, Android 8.0 or newer). The kernel and the page run on the phone, and
-the agent reaches your servers over SSH; pairing with a computer is done by
-scanning the code it shows.
-
-The APK is signed with the Android release key rather than minisign, so it
-carries a `.sha256` and no `.minisig`.
-
-When that key is absent the build is named
-`ReasonixMobile-<version>-unsigned.apk`. Android refuses to install an unsigned
-package, so those builds stay a workflow artifact for whoever wants to sign one,
-and the release carries no APK at all.
-
-### Reasonix 1.x (stable)
-
-The 1.x CLI installs through npm on any supported platform, or Homebrew on
-macOS:
-
-```sh
-npm i -g reasonix                  # any OS; pulls the prebuilt native binary
-brew install esengine/reasonix/reasonix   # macOS
-```
-
-The 1.x desktop app is on the
-[official download page](https://reasonix.io/?download=desktop#start). Windows
-installers are code-signed with a Certum code-signing certificate.
-
-### VS Code extension
-
-The extension does not bundle the CLI; it starts your local `reasonix acp`
-backend and adds native chat, editor context, tool-call approvals, model
-selection, and workspace sessions. Install the 1.x CLI first.
-
- **VS Code:** [install from Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=SivanLiu.reasonix-agent)
- **VSCodium / Eclipse Theia:** [install from Open VSX Registry](https://open-vsx.org/extension/SivanLiu/reasonix-agent)
- **Extension ID:** `SivanLiu.reasonix-agent` · [source and usage guide](https://github.com/SivanCola/reasonix-vscode)
-
-### Build from source
-
-Clone the repository; `studio` builds 2.x and `main-v2` builds 1.x:
-
-```sh
-git clone https://github.com/esengine/DeepSeek-Reasonix.git
-cd DeepSeek-Reasonix
-git switch studio
-```
-
-#### CLI
-
-The CLI build requires **Go 1.25+**. The module pins a `toolchain` directive;
-keep `GOTOOLCHAIN=auto` so Go downloads the pinned toolchain, or install it.
-
-```sh
-make build      # -> bin/reasonix(.exe)
-make cross      # -> dist/ (darwin|linux|windows × amd64|arm64)
-```
-
-#### Studio
-
-Studio additionally requires **Node 24+ and pnpm 10**
-(`npm install -g pnpm@10`) for the frontend.
-
-```sh
-make studio
-```
-
-See the [Studio build guide](desktop/README.md#prerequisites) for platform
-webview dependencies and Linux build tags.
-
-## Quick start
-
-### Reasonix Studio
-
-Install and launch Studio, then connect a provider and model in the app. No CLI
-setup is needed.
-
-### CLI / TUI
-
-```sh
-reasonix setup                      # configure a provider and model
-reasonix                            # start an interactive session
-reasonix run "implement the TODOs in main.go"
-```
-
-In an interactive session, run `/init` when you want Reasonix to create project
-instructions.
-
-For advanced CLI usage and configuration, see the **[CLI reference](./docs/CLI.md)**,
-**[Guide](./docs/GUIDE.md)**, and
-**[configuration paths](./docs/CONFIG_PATHS.md)**.

-</p>
+## Quick start (60 seconds)
+
+**1. Get a DeepSeek API key.** Free credit on signup:
+<https://platform.deepseek.com/api_keys>
+
+**2. Point it at a project.** No install needed.
+
+```bash
+cd my-project
+npx reasonix code
+```
+
+First run walks you through a 30-second wizard (paste API key → pick
+preset → multi-select MCP servers). Every run after that drops you
+straight in.
+
+**3. Ask it to edit.** The model proposes edits as SEARCH/REPLACE
+blocks — nothing hits disk until you `/apply`.
+
+```
+reasonix code › users.ts 里 findByEmail 对大小写敏感导致登录失败，帮我改
+
+assistant
+  ▸ tool<search_files> → src/users.ts, src/users.test.ts
+  ▸ tool<read_file>    → (src/users.ts, 412 chars)
+  ▸ 找到了。findByEmail 直接用 === 比对。改成小写规范化并补一条测试。
+
+src/users.ts
+<<<<<<< SEARCH
+  return users.find(u => u.email === email);
+=======
+  const needle = email.toLowerCase();
+  return users.find(u => u.email.toLowerCase() === needle);
+>>>>>>> REPLACE
+
+▸ 1 pending edit across 1 file — /apply to write · /discard to drop
+
+reasonix code › /apply
+▸ ✓ applied src/users.ts
+```
+
+Requires Node ≥ 20.10. macOS, Linux, Windows (PowerShell / Git Bash /
+Windows Terminal). Press `Esc` anytime to abort; `/help` for the full
+command list.

+## `reasonix code` — pair programmer in your terminal

-If Reasonix has been useful and you'd like to say thanks, you can. It stays a
-coffee, not a contract — donations don't buy feature priority or change how
-issues get triaged.
+Scoped to the directory you launch from. The model has native
+`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.

+### Walkthrough: explore before editing

-<p align="center">
-  <img src=".github/sponsor/wechat-pay.jpg" alt="WeChat Pay QR code" width="180"/>
-  <img src=".github/sponsor/alipay.jpg" alt="Alipay QR code" width="180"/>
-</p>
+For "what does this code do?" questions the model uses the read-side
+tools and replies in prose — no SEARCH/REPLACE blocks, no file
+writes. Ask to change something only when you mean it:
+
+```
+reasonix code › 这个项目的路由是怎么组织的？
+assistant
+  ▸ tool<directory_tree> → (src/ tree, 47 entries)
+  ▸ tool<read_file> → (src/router.ts, 1.2 KB)
+  ▸ 路由分三层：顶层 AppRouter 注册 tab，每个 tab 用 React Router 的
+    nested routes 写子路径，最后 …
+```
+
+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.
+
+### Plan mode — review before executing
+
+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**:
+
+```
+reasonix code › 把 auth 从 JWT 迁移到 session cookies
+
+▸ 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.
+
+### 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).
+
+---
+
+## `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).

+## Library usage
+
+```ts
+import {
+  CacheFirstLoop,
+  DeepSeekClient,
+  ImmutablePrefix,
+  ToolRegistry,
+} from "reasonix";
+
+const client = new DeepSeekClient(); // reads DEEPSEEK_API_KEY from env
+const tools = new ToolRegistry();
+
+tools.register({
+  name: "add",
+  description: "Add two integers",
+  parameters: {
+    type: "object",
+    properties: { a: { type: "integer" }, b: { type: "integer" } },
+    required: ["a", "b"],
+  },
+  fn: ({ a, b }: { a: number; b: number }) => a + b,
+});
+
+const loop = new CacheFirstLoop({
+  client,
+  tools,
+  prefix: new ImmutablePrefix({
+    system: "You are a math helper.",
+    toolSpecs: tools.specs(),
+  }),
+  harvest: true,
+  branch: 3,
+});
+
+for await (const ev of loop.step("What is 17 + 25?")) {
+  if (ev.role === "assistant_final") console.log(ev.content);
+}
+console.log(loop.stats.summary());
+```
+
+`ChatOptions.seedTools` accepts a pre-built `ToolRegistry` for
+callers who want the `reasonix code` loop wiring without the CLI
+wrapper. See [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) for
+internals.
+
+---
+
+## 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 |
+|---|---|---|
+| 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 |
+
+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:
+
+| 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
+npx reasonix diff \
+  benchmarks/tau-bench/transcripts/t01_address_happy.baseline.r1.jsonl \
+  benchmarks/tau-bench/transcripts/t01_address_happy.reasonix.r1.jsonl
+```
+
+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.
+
+Full 48-run report:
+[`benchmarks/tau-bench/report.md`](./benchmarks/tau-bench/report.md).
+Reproduce with your own API key: `npx tsx
+benchmarks/tau-bench/runner.ts --repeats 3`.
+
+MCP reference runs (one single prefix hash across all 5 turns even
+with two concurrent MCP subprocesses):
+
+| server | turns | cache hit | cost | vs Claude |
+|---|---:|---:|---:|---:|
+| bundled demo (`add` / `echo` / `get_time`) | 2 | **96.6%** (turn 2) | $0.000254 | −94.0% |
+| official `server-filesystem` | 5 | **96.7%** | $0.001235 | −97.0% |
+| **both concurrently** | 5 | **81.1%** | $0.001852 | −95.9% |
+

+
+## 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.

-## 它是什么
-
-Reasonix 是一个开源的 AI 编程助手。程序跑在你的电脑上；AI 模型是你自己配置的服务，它读到的内容会发给这个服务。你用大白话描述任务，它在你选的项目文件夹里读代码、改文件、跑命令和测试，每一步都摆给你看。
-
-模型你自己选：内置 DeepSeek 预设，其他兼容 OpenAI 接口的服务填一条配置就行，费用直接付给模型服务商。
-
-## 你能得到什么
-
- **读、改、跑**：读你的项目、改文件、跑测试和命令，都在你选的项目文件夹里。
- **权限分档**：每次都问你，或让日常操作自动放行；你设的禁止规则始终有效。想先看方案，就开计划模式，批准后它才动手。
- **可回退**：改文件前先存快照，按对话轮次回退，不碰 git 历史。只覆盖编辑工具改的文件，命令行命令造成的改动不在内。
-
-## 30 秒上手
-
-下载、填模型密钥、打开项目。第一次用，从桌面应用 Studio 开始。
-
-1. 从[发布页](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true)下载并安装桌面应用 Reasonix Studio。
-2. 打开应用，按提示填入模型服务商和密钥。
-3. 打开你的项目文件夹，写下想做的事，例如“给 http 客户端加上失败重试”。
-4. 按你选的档位，该问你的操作它会先停下来问；同意就继续，不同意就拒绝。
-
-更喜欢终端的话，下载 `reasonix` 命令行后运行 `reasonix setup` 配好模型，再运行 `reasonix` 即可。详见[安装](#安装)和[快速开始](#快速开始)。
-
-## 四种用法
-
- **桌面应用（Studio）**：图形界面，适合第一次使用。
- **终端**：全屏文字界面，也能用 `reasonix run "任务"` 在脚本里运行。
- **浏览器**：`reasonix web` 在本机打开网页界面。
- **编辑器**：VS Code 安装扩展即可；其他支持 ACP（Agent Client Protocol，编辑器接入某个 AI 助手的通用约定）的编辑器，可连接 `reasonix acp`。
-
-四种用法背后是同一套程序。下面的内容写给进阶用户和贡献者。
-
-## 在 DeepSeek Harness 里使用
-
-DeepSeek Harness（`dsh`）可以通过 ACP 把任务交给 Reasonix 作为子智能体去做。本仓库为此发布了一个插件索引：
-
-1. 在运行 `dsh` 的机器上先运行 `reasonix setup`。在 DSH 网页界面打开“自定义插件市场”（插件，更多），再到 Discover 页添加这个索引：`https://raw.githubusercontent.com/esengine/DeepSeek-Reasonix/studio/integrations/dsh-plugin/market-index.json`
-2. 从中安装“Reasonix subagent”。
-3. 打开这个插件的页面，把它的开关打开。关着的时候模型没有 `reasonix` 工具，可能改在自己的 shell 里直接运行 `reasonix -p`，看起来像委派，其实不是。
-
-配置细节、权限策略和限制见 [在 DeepSeek Harness 中使用 Reasonix](./docs/DSH.md)。
-
-## 版本
-
-Reasonix 分为两条版本线，调整的原因见[版本路线公告](https://github.com/esengine/DeepSeek-Reasonix/discussions/10748)。
-
-| 版本线 | 分支 | 状态 | 获取方式 |
-| --- | --- | --- | --- |
-| **Reasonix 2.x** | `studio`（当前分支） | 活跃开发 | [Studio 发布页](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true) |
-| **Reasonix 1.x** | [`main-v2`](https://github.com/esengine/DeepSeek-Reasonix/tree/main-v2) | 维护 / 稳定 | `npm i -g reasonix` · [桌面端下载](https://reasonix.io/?download=desktop#start) |
-
- **想要稳定**：继续使用 1.x。它会持续收到 Bug 修复、Provider / API 兼容、
-  更新器和安全修复，但不再扩展核心架构。
- **想体验新架构**：使用 2.x Reasonix Studio。它仍在快速迭代，欢迎反馈问题。
-
-1.x 中有价值的修复、测试和行为会逐项 review，适合新架构的会迁移或重新实现到 2.x。
-
- [从 1.x 迁移到 2.x](./docs/MIGRATING.md)（英文）：两条线共用哪些数据，以及如何在同一台
-  机器上同时使用而不丢会话。
- [2.x 路线图](./docs/ROADMAP.md)（英文）：2.x 还要交付什么、如何发布、哪些决定尚未做出。
-
-## 特性
-
-以下是写给进阶用户的技术要点。
-
- **配置驱动**：provider、agent、启用的工具、插件全部在 `reasonix.toml` 中声明，
-  内核无硬编码模型。
- **多模型 · 可组合**：DeepSeek 作为预设内置；任何 OpenAI 兼容
-  端点都只是一条配置。可选让两个模型协同（执行器 + 规划器），各自独立、缓存稳定的 session。
- **插件驱动**：MCP server 提供工具、提示词和资源；Extension Protocol v1
-  Sidecar 还可以拦截运行时事件、提供 Provider 与结构化 UI，并通过版本化插件包分发。
- **缓存友好的上下文维护**：启动时注入稳定的环境摘要；旧工具输出会先 snip/prune，
-  再进入摘要 compaction；内置工具 schema 合约有文档和回归测试保护。
- **零摩擦分发**：`CGO_ENABLED=0` 单二进制；一条命令交叉编译到六个目标平台。
-  产物是完全自包含的静态二进制——目标机器上除二进制本身外无需安装任何东西。
-
-## 安装
-
-当前分支是 **Reasonix 2.x**，桌面端是 Reasonix Studio；CLI、Studio 和编辑器集成
-都运行同一套本地 Reasonix 引擎。
-
-### Reasonix Studio（2.x）
-
-从最新的 [Studio 发布](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true)
-下载对应平台的安装包（标签为 `studio-v2.*`；`-rc.N` 等候选版本标为预发布）：
-
-| 平台 | 安装包 | 架构 |
-| --- | --- | --- |
-| macOS | `.dmg` 或 `.zip` | Apple Silicon（`arm64`）/ Intel（`amd64`） |
-| Windows | 安装器 `-installer.exe` 或便携 `.zip` | x64 |
-| Linux | `.deb`、`.rpm` 或 `.AppImage`（只提供下载） | x64（`amd64`）/ ARM64（`arm64`，aarch64） |
-
-每个安装包都附带 `.minisig` 签名，发布页另有 `SHA256SUMS`。安装后 Studio 会在
-应用内自行更新。
-
-同一个发布页也提供 2.x 的 `reasonix` CLI 归档（`darwin|linux|windows × amd64|arm64`）。
-
-安卓版在同一个发布页上，文件名是 `ReasonixMobile-<版本>.apk`（`arm64`，Android 8.0 及以上）。
-
-这个 APK 用 Android 发布密钥签名，不走 minisign，因此只有一个 `.sha256`，没有 `.minisig`。
-
-该密钥缺失时产物名为 `ReasonixMobile-<版本>-unsigned.apk`。Android 不接受未签名的包，
-这类构建只留作 workflow 产物供自行签名，发布页上不会挂 APK。
-
-内核与界面都跑在手机上，Agent 通过 SSH 连接你自己的服务器；与电脑配对时扫它显示的二维码。
-
-### Reasonix 1.x（稳定版）
-
-1.x CLI 在任意支持的平台上都可以通过 npm 安装，macOS 也可以使用 Homebrew：
-
-```sh
-npm i -g reasonix                  # 任意系统;自动拉取对应平台的原生二进制
-brew install esengine/reasonix/reasonix   # macOS
-```
-
-1.x 桌面端请前往[官方下载页](https://reasonix.io/?download=desktop#start)。
-Windows 安装器使用 Certum 代码签名证书签名。
-
-### VS Code 扩展
-
-扩展不内置 CLI，而是启动本机的 `reasonix acp` 后端，并提供原生聊天、编辑器
-上下文、工具调用审批、模型选择和工作区会话。请先安装 1.x CLI。
-
- **VS Code：** [从 Visual Studio Marketplace 安装](https://marketplace.visualstudio.com/items?itemName=SivanLiu.reasonix-agent)
- **VSCodium / Eclipse Theia：** [从 Open VSX Registry 安装](https://open-vsx.org/extension/SivanLiu/reasonix-agent)
- **扩展 ID：** `SivanLiu.reasonix-agent` · [源码与使用说明](https://github.com/SivanCola/reasonix-vscode)
-
-### 从源码构建
-
-克隆仓库；`studio` 构建 2.x，`main-v2` 构建 1.x：
-
-```sh
-git clone https://github.com/esengine/DeepSeek-Reasonix.git
-cd DeepSeek-Reasonix
-git switch studio
-```
-
-#### CLI
-
-CLI 构建需要 **Go 1.25+**。模块固定了 `toolchain`，保持 `GOTOOLCHAIN=auto`
-即可让 Go 自动下载对应工具链，也可以手动安装。
-
-```sh
-make build      # -> bin/reasonix(.exe)
-make cross      # -> dist/（darwin|linux|windows × amd64|arm64）
-```
-
-#### Studio
-
-Studio 的前端还需要 **Node 24+ 与 pnpm 10**（`npm install -g pnpm@10`）。
-
-```sh
-make studio
-```
-
-各平台的 webview 依赖和 Linux 构建标签见 [Studio 构建指南](desktop/README.md#prerequisites)。
-
-## 快速开始
-
-### Reasonix Studio
-
-安装并启动 Studio，然后在应用内连接 provider 和模型即可使用，无需配置 CLI。
-
-### CLI / TUI
-
-```sh
-reasonix setup                      # 配置 provider 和模型
-reasonix                            # 启动交互式会话
-reasonix run "把 main.go 里的 TODO 实现掉"
-```
-
-需要项目指令时，可在交互式会话中运行 `/init`。
-
-CLI 进阶用法和详细配置见 **[CLI 命令参考](./docs/CLI.zh-CN.md)**、
-**[指南](./docs/GUIDE.zh-CN.md)** 和
-**[配置路径](./docs/CONFIG_PATHS.md)**。

-# Reasonix project memory
-
-This file is loaded into every session's system prompt (the cache-stable prefix),
-so keep it concise and durable — it is the project's standing instructions to the
-agent. It is the Reasonix analog of Claude Code's CLAUDE.md.
-
-## Conventions
-
- Go kernel under `internal/`; each package owns one concern. A package's long
-  explanation belongs in its `doc.go`, not spread across implementation files.
- One transport-agnostic `control.Controller` sits behind every frontend (chat
-  TUI, HTTP/SSE serve, Electron desktop). Add behavior to the controller, not a
-  frontend, so all three inherit it.
- Layering (enforced): utility packages import nothing under `reasonix/` except
-  one another — that layer is closed, so a leaf reaching a leaf drags no graph
-  along, while refusing it leaves one judgement copied into several of them; only
-  the frontends `cli`, `serve`, `acp`, `boot` and the hosts `cmd/`, `desktop/`
-  may import `control`; nothing below a frontend may import one. The declared
-  sets live in `tools/repolint/layers.go`.
- Subagent delegation keeps five concepts apart: a profile says how a worker
-  thinks, `TaskSpec` what this call wants, `CapabilityGrant` what it may touch,
-  `ContextRequest` what it starts from, `SchedulerPolicy` when it runs. Put a
-  field in whichever member decides its value — profiles carry ceilings, never
-  per-call values. `internal/runtime/delegation/profile_boundary_test.go` enforces it.
- Cache-first: the system-prompt prefix (base prompt, tools, declared prefix
-  configuration) must stay byte-stable across turns so DeepSeek's automatic
-  prefix cache stays warm. Never mutate it mid-session — ride the turn tail
-  instead (see `control.Compose`), under the rules in *Context projection*.
- Performance features land with an effect test at their final boundary
-  (`internal/assembly/boot/effect_test.go` pattern): assert what actually reaches the
-  provider request, frontend sink, or trajectory through the real `boot.Build`
-  assembly. Component correctness is not system effectiveness.
- A mutex- or atomic-guarded struct is ratcheted on its **scalar** field count
-  (`struct-state`), not its total: independent flags multiply into states no
-  type records as legal. Fixing a boundary case by adding one more `bool` is
-  the move this blocks — group by lifetime into a named sub-state instead
-  (`agent.perTurnState` is the pattern), which costs one field and removes the
-  whole product.
- The context window (projection, compaction, estimation) owns `windowState`;
-  the loop reaches it via `a.window()`, it reaches the loop via `windowHost`.
-  `window-state` fails any other read of `sess.win`.
- Judgements read structure, never wording: shell ASTs (`shellparse`), types,
-  contracts, tool schemas. Phrase tables and message sniffing have been retired
-  in batches (task-policy prose, the planner's approval phrases, the executor
-  handoff tables) because each one misfires on real input, and a misfiring
-  judgement inside a gate is worse than no gate. Security allow-lists are the
-  exception and stay. Something that can only be built by matching words does
-  not get built — say what is missing instead of guessing at it.
- The other half of that rule: an error a caller must tell apart **carries an
-  identity** — a sentinel, a typed code — never a sentence. Only the producer
-  knows a deadline expired rather than a socket closed, and a message is where
-  that knowledge goes to die: the reader is left matching words, or with
-  nothing. Across HTTP the identity is a dotted code through `refuse`;
-  `refusal-path` fails a new `http.Error` in `internal/frontend/serve`, and the parity
-  test fails a code the frontend cannot say. Inside Go it is `errors.Is` on a
-  sentinel the wrapping preserves; `error-text` fails a new match against an
-  error message, following it one hop into a local because storing the text
-  first is what the direct form turns into.
- **Whoever first knows why an operation failed owns its class.** A transport
-  status is not a domain identity, and a display string is not a classification;
-  past that boundary a layer may project the class, never re-derive it. Both
-  directions were live: `catalog.go` answered 400 for a name nobody declared and
-  for a disk that would not write, so a failed store told the user their request
-  was wrong; `ServerRow` decided a connection was an authorisation problem by
-  matching `/401|403|unauthorized/` against prose an external MCP server wrote,
-  which the host had sanitised and truncated on the way through. Domain,
-  internal and dependency are three answers with three different things to do
-  next, and a caller that cannot tell them apart reports the last two as the
-  first.
- Failure attribution is host-owned state. When the host can determine why an
-  operation failed or stopped — truncation, timeout, unavailable context,
-  dependency skipping, policy refusal, output spill, argument parsing — that
-  cause goes to the model. Surfacing only the downstream symptom leaves it to
-  invent one, and the invented rule outlives the incident: a response cut at the
-  output limit reaches the model as "invalid arguments", and the session learns
-  to stop batching calls that were never the problem.
- A host-owned identity has to cross the model-visible boundary. Stable step
-  ids, typed error codes, boundary causes — anything the host expects the model
-  to cite must appear wherever that state is rendered for it. Telling the model
-  in a schema to prefer X while every concrete rendering shows only Y trains it
-  to use Y; `complete_step` said `step_id` PREFERRED while all four todo
-  renderers printed bare ordinals. Canonical dynamic state still stays out of
-  the cache-stable prefix — project the identities needed to act on it at the
-  turn tail.
- A metric is its definition, not its name. Before a number becomes a finding,
-  state what it counts, from which anchor, over which population, and what it
-  excludes. Three readings in one study died in that gap: a command of unknown
-  extent read as a proven write, the latest report's adjudication read as every
-  report's, and a syntactically accepted call read as a closed one. Each time a
-  convenient proxy had been left standing in for the state it was named after,
-  and each time the mechanism story built on it was wrong. A number without
-  those four lines is an observation, not a result.
- A constructed state is not a reachable one. Before a destructive test or a
-  counterfactual is reported as a defect, say who in production produces that
-  state, through which transitions, across which persistence boundary, under
-  whose authority, and whether a real run has been seen reaching it. A test that
-  assigns a private field proves the mechanism *given* the state and must be
-  reported as exactly that: `a.projectChecks` is written once at boot and never
-  again, so reassigning it stood in for a resume rather than demonstrating one,
-  and the bypass built on it was never shown to be production-reachable.
-  Severity is reachability times frequency times authority, not "can be
-  bypassed".
- A wire type the desktop re-declares by hand is held to the kernel's by
-  `wire-parity`, both directions: a field one side sends and the other cannot
-  read fails, and so does one it reads that nothing sends. The two are compiled
-  by different toolchains and meet only over JSON, so nothing else in the tree
-  notices when one of them grows a field. The pairs are declared in
-  `tools/repolint/wireparity.go`, never inferred — no spelling tells a mirrored
-  contract from a struct that merely carries json tags.
- "Add behavior to the controller so every frontend inherits it" is held by
-  `frontend-parity`: a capability one frontend already drives, a frontend whose
-  declared port carries it, and no call, is a missing edge, and the ratchet
-  counts edges. Which port each frontend drives is declared in
-  `tools/repolint/frontendparity.go`; a deliberate exception goes in the scope
-  table there with an issue and a reason, and costs what the edge cost, so the
-  table cannot become where debt disappears. The matrix is read from
-  `go/types` at one pinned build target, never from selector names — `Close`
-  and `Status` are capabilities and also stdlib methods, and a name match
-  records `os.File.Close` as a frontend driving `Lifecycle.Close`, a false
-  "wired" that hides real debt. How a verb is spelled — `/branch`,
-  `POST /branches` — is presentation and stays out of it.
- The desktop's presentation layer answers to canonical state and never
-  redefines it. Six rules, each held by a gate rather than by memory:
-  presentation reorders and reweights what the kernel owns but never restates
-  it; **mount is not a motion cause** — a fact enters once, and replay or
-  virtualization bringing its element back is not that fact happening again;
-  a search alias buys discoverability and never becomes a thing's identity;
-  when a setting takes effect is declared per block, from what its endpoint
-  does, never inferred from wording or handler names; ordering panels by
-  lifecycle moves them and must not remount them; and a control's identity
-  survives a change of where it is drawn — the settings sheet and the composer
-  render `chrome.preset` because that is one intent, not two.

-## Comments
-
-Default is none — the code is the truth. Write one only when the **why** is
-non-obvious: a hidden constraint, a workaround anchored to something verifiable,
-an invariant the type system cannot express, or an external-protocol quirk.
-
-A comment states the constraint that holds now. It does not narrate how the code
-got here: a reader who has never seen an earlier version must lose nothing, and
-past tense about this code's own behaviour is the tell — an external protocol's
-history is not. "Ids alone do not answer it" is the rule; "ids alone were the
-wrong question, so the list went on reading as the model wrote it" is the
-incident behind the rule, and the incident belongs in the commit message. This
-outranks the surrounding style: much of the tree reads as prose and none of it
-is the standard. No gate reads register — telling narrative from a statement of
-constraint needs a phrase table, which is the one thing this repo does not
-build — so this rule is held by review.
-
- **Stylesheets carry none.** A rule's selector and its declarations are the
-  whole statement. What a `.css` comment would have said goes to whichever of
-  two places can act on it: a constraint a component has to honour belongs in
-  that component, and a decision about the medium itself — a measured colour, a
-  layout mechanic, why the obvious rule is the wrong one — belongs in the
-  stylesheet's companion document (`src/styles/TOKENS.md`, `LAYOUT.md`), which
-  is read end to end rather than met 600 times as an aside.
- **English, always** — every comment, in every other language the tree is
-  written in. A codebase whose commentary is half one language reads as two
-  codebases, and the half a given reader cannot read is the half that rots.
- Declaration doc: ≤5 lines. Package comment: ≤8 lines, or ≤40 in a `doc.go`.
- Every other comment: ≤3 lines. Struct-field and trailing `//`: 1 line.
- Never: restatements of the code, phase/stage narrative, incident or
-  conversation history, section banners, commented-out code, `@param` lists.
- `TODO(#nnn):` and `HACK(#nnn):` need the issue anchor. `FIXME` is banned.
- One responsibility per file; 800 lines is the ceiling. Test files are exempt:
-  their length tracks how many cases they cover, not how many concerns they
-  carry, so splitting one only scatters a subject's table across files.
-
-`go run ./tools/repolint` enforces the budgets above against a ratchet baseline:
-recorded debt is tolerated, anything new fails CI. Never widen the baseline to
-land a change — fix the code. `-update` lowers budgets freely and refuses to
-raise one without `-allow-widen`, so carrying debt through a rename or an
-extraction is asked for in the command and justified in the PR. A clean run also
-reports budget the tree stopped using: it is only reclaimed by an `-update`, and
-until then it is room a file can grow back into.
-
-## Context projection
-
-Canonical dynamic state — the skill registry, the memory store — lives in its own
-owner, and what the model sees is a projection of it onto each request. The
-prefix was never where these belonged wrongly; freshness ownership was missing.
-
- **Prefix ownership.** Only declared prefix configuration may move the
-  cache-stable prefix; ordinary memory writes, skill writes and runtime facts
-  ride the turn. Pinned memory bodies are the one declared exception, because
-  pinning is a request to pay one cold start.
- **Projection freshness.** When canonical state changes, the next eligible turn
-  carries the new projection or can say why it is not owed. "Right after a fold,
-  or in the next session" is not an answer.
- **Projection ownership.** Whoever owns a dynamic fact owns the invalidation
-  that makes its projection owed again. A projection kept fresh because every
-  writer remembered to announce itself is one forgotten call from stale —
-  `skillSet.owedCatalog` asks the registry rather than waiting to be told.
- **Determinism.** The same canonical state and the same projection state
-  produce byte-identical model-visible bytes.
- **Detection is semantic.** Freshness may not rest on writer notification, on
-  mtime, or on which call path made the change. The registry answers from
-  canonical state, so a switch flipped and a file edited past every API are the
-  same question, and a change no projection renders is not a change.
-
-`internal/assembly/boot/context_projection_test.go` holds all five at the provider
-boundary, with the skills listing and the standing instructions as the two
-worked examples. A block is settled only once the turn carrying it reaches the
-runner: a turn blocked by a hook or refused by an extension after composing put
-those bytes nowhere, and clearing the debt there would leave the model holding
-state nobody sent it. A projection that has become empty is still owed once —
-otherwise the block the model already has goes on reading as current.
-
-## Memory
-
- Standing instructions are hierarchical: committed/shared `REASONIX.md`,
-  `AGENTS.md`, and `CLAUDE.md`; personal `*.local.md` variants; matching files in
-  ancestor directories; and user-global files under the memory state root
-  (`REASONIX_STATE_HOME`, otherwise `REASONIX_HOME`, otherwise `~/.reasonix` on
-  macOS/Linux or `%APPDATA%\reasonix` on Windows). All distinct supported files
-  in a directory load; `AGENTS.md` is not merely a fallback.
- `@path` on its own line imports another file's contents.
- `#<note>` in chat quick-adds an always-on instruction. The `remember` tool
-  instead saves a fallible background fact (frontmatter file + `MEMORY.md`
-  index). Fact `type` classifies content; independent `scope` controls whether it
-  is project-only (the default) or explicitly global.
- The saved-fact index stays out of the stable prefix and is reached through the
-  `memory` tool; pinned bodies and global user/feedback bodies load into it, the
-  latter as lower-priority compatibility guidance. The current turn receives a
-  tail note.
-
-## Notes
-
-One tool call costs one model round trip, so calls that do not depend on each
-other belong in the same round: several reads, edits to different files, a check
-after the edit that enables it. Several edits to the *same* file are one
-`multi_edit` — it applies them against each other in memory and rewrites the
-file only if all of them land, so a failure midway leaves nothing half-edited.
-
-## Vendor rates
-
-Official list prices live in one place: `officialRates` in
-`internal/contract/pricing/rates.go`, oldest generation first, the last being what a
-model charges today. A price change is an **append, never an edit** — the
-superseded rate is what lets an installed config be recognised as holding one
-of ours and brought forward, instead of quoting a retired rate for the rest of
-its life. `config` reads these through `pricing.CurrentRate` and
-`SupersededRates` and restates none of them; a table written twice is one that
-drifts, which is how a vendor's USD rate ended up published on one side only.
-
-`make pricecheck` reads each vendor's own page and compares it against that
-table, and reports how long ago a person last confirmed each one. It reaches
-the network, so it stays out of `make lint` and out of CI: run it before
-touching a rate and when a vendor announces a change. A page it cannot read
-exits non-zero — unread is its own verdict and never counts as agreement.
-
-## Curated presets
-
-A preset changing shape reaches the installs that already have the old one
-through `shippedPresets` in `internal/contract/config/preset_upgrade.go`: one declared
-shape per generation, and one upgrade that brings a matching entry forward. The
-guard is the whole shape — catalog, window, default — because an entry holding
-what we shipped is ours to move and anything else its user curated.
-
-A preset is also what settles which of its models read images. Probing an
-address a preset covers answers from that declaration, because reading a name
-misses every Kimi, Qwen, MiniMax and Claude model they declare and `deepseek-
-flash` spells nothing at all; the spelling is the last resort for an address
-nothing has declared, and stays a correctable suggestion rather than a claim.
-
-Three distinctions are load-bearing, and each was a separate migration function
-before they were written down. A window the shape did not name is the user's,
-so only a shape identified by its window moves one. `vision_models` **narrows**,
-so an upgrade marks only the models it adds and only where the preset says they
-read images. And an explicitly empty list is a choice — nothing here reads
-images — which is not the same as the nil that means nobody has said.
-
-## Pre-push CI simulation
-
-Run these **before every commit** to catch the fastest CI failures locally:
-
-```bash
-gofmt -w .                          # catches gofmt (saves ~13s CI)
-go vet ./...                        # catches vet warnings (saves ~52s CI/lint)
-make lint                           # golangci-lint at CI's pin + repolint
-go test ./internal/tools/builtin/ ./internal/assembly/boot/  # catches tool/boot test breaks
-```
-
-`make lint` runs both gates CI runs, at the version in `.golangci-version`;
-`make lint-install` installs it. Do not skip it: a `modernize` finding never
-shows up in `go vet`, and the CI round trip that catches it instead costs ten
-minutes.
-
-A full repolint run reports every file over budget, including debt your change
-never touched. To see only what your own edits owe:
-
-```bash
-make check
-```
-
-Repo-wide ceilings still report under a narrowed run, because a file can push
-the tree past one without exceeding its own budget.
-
-`make check` owns the evidence-bearing changed-file universe — everything the
-worktree altered *and* everything it added that git has not been told about.
-Never substitute a direct `go run ./tools/repolint` invocation for it when
-recording verification evidence: the host recognizes a `make` target as a check
-whose result it can read, while an arbitrary `go run ./tools/...` is a program
-it has to assume writes, and the flags behind the target are its implementation
-rather than the contract. Building that universe from `git diff` alone once let
-a new file reach the gate unopened and be reported clean.
-
-## Import cycle rule
-
-Before importing a new internal package from a non-test file, verify the target package's **test files** aren't already importing back to you:
-
-```
-# BAD: agent(_test.go) → tool/builtin(sessions.go) → agent  → setup failed
-```
-
-Use `go test ./path/to/target/` to detect cycles **before** pushing. A `[setup failed]` message means a cycle exists.
-
-## PR hygiene
-
- **One force-push per round of review feedback.** Multiple force-pushes destroy review history and confuse reviewers.
- **Keep the PR diff minimal.** Only the files relevant to the PR's purpose — no stray changes from other branches.
- **Amend, don't add commits, for review feedback** — keeps the commit history clean.
-
-## Change discipline
-
-**Assess before editing.** For every change, humans and agents list callers,
-consumers of the same state, sibling features, reload/replay/restart paths,
-error and edge states, TUI/CLI and desktop equivalents, and wire mirrors.
-
-A fix that breaks a neighbouring behaviour is a failed fix.
-
-**Test the neighbourhood.** UI changes add or extend interaction tests for
-adjacent functions of the same component or flow (composer: submit, clear,
-queue, withdraw, restore, steer, failure, replay after reload) and run the whole
-affected suite.
-
-Write tests first; they must fail without the change.
-
-**Fix at the owning layer.** Use the existing unified pattern: no special-case
-flags, duplicated paths, or workarounds at the symptom site.
-
-If the design is duplicated or wrong, make the smallest unifying change:
-one path instead of two, deleting what becomes dead. Use current language and
-framework idioms; do not add a new pattern where one exists.
-
-**PR evidence.** Every PR description carries: Cause, Blast radius,
-Neighbouring behaviours tested, and Why this layer.
-
-## Reasonix host checks
-
-The paths below decide what the agent is allowed to do — a wrong change here
-is not a bug in a feature, it is a hole in a boundary. Declaring them makes
-every change under them demand `review` plus `security_review` before a turn
-can finish. Sensitivity is declared, never inferred: the host does not read it
-out of how a path is spelled, which cannot tell `internal/auth` from
-`session_write_authority.go`, or a trace file from a data race.
-
- sensitive: internal/safety/permission/**
- sensitive: internal/safety/sandbox/**
- sensitive: internal/safety/shellsafe/**
- sensitive: internal/base/shellparse/**
- sensitive: internal/session/control/approval.go
- sensitive: internal/session/control/approval_bridge.go

-
-One declaration, two effects: the same list is also the coverage gate's subject.
-`make coverage-gate` holds each path to the coverage it already has, because
-when this was written these paths sat *below* the tree's median rather than
-above it — the code deciding what the agent may execute was its least-tested
-part. Floors ratchet like repolint's budgets: raising one is free, lowering one
-needs `-allow-drop` and a reason in the PR. Adding a `sensitive:` path gets both
-effects; there is no second list to keep in sync.
-
-## Trust domain
-
-Three sets, kept apart because conflating them turns a performance number into a
-security claim: **VerificationRelevant** (state that can change whether a
-delivery claim holds), **Observable** (state the host can reconcile after an
-action, so it can say what that action did), **HostProtected** (state a
-capability/sandbox boundary makes unwritable). The invariant is
-`Writable ∩ VerificationRelevant ⊆ Observable ∪ HostProtected`:
-
-> Any state that can both be modified by an action and influence the delivery
-> claim must either be observable by the host or protected from modification by
-> host-enforced boundaries. An incomplete observation never establishes scope.
-
-Effects and state answer different questions and never stand in for each other —
-observation proves what an action did, verification proves what the resulting
-state satisfies — which is why `unproven_mutation` is settled only by
-observation, never by a check that ran afterwards.
-
-What follows bounds Observable today. It is not a restatement of the invariant:
-moving a number here must not move the promise.
-
- `scanWorkspace` walks the workspace and every granted extra root recursively,
-  skips VCS store dirs, and is `complete` only below 50k files in total. Over that, or past a walk error, it
-  establishes nothing and the mutation stays unproven.
- Symlinks are recorded by `Lstat`, so a write through one lands outside what
-  the walk compares. Confining the resolved target is the sandbox's job.
- `internal/safety/sandbox` confines writes to the workspace, configured extras, temp
-  and toolchain caches on macOS and Linux.
- On Windows a user-enabled write-restricted token bounds the *creation* of files
-  (create, append, overwrite, `mkdir`, HKCU writes, global git config, writes through links).
- There, deleting or renaming away an existing file is not bounded, and with the
-  setting off nothing the host enforces bounds `Writable`.
- The caches a command may write can be poisoned for the user's later unsandboxed
-  builds, on every platform.
- The governed host authorities are a *named* set — ssh-agent, docker, podman.
-  DBus, Wayland, X11, gpg-agent, keyrings and arbitrary sockets stay reachable,
-  so the claim is "these endpoints are governed", never "host IPC is isolated".
-
-`stateEpoch` tracks host-observed mutations, not an exact filesystem snapshot;
-unobserved external writers are a gap shared by the whole verification model. Go
-baseline test criteria use the toolchain's build overlay and therefore share
-ordinary verification's epoch semantics; the overlay is not a general filesystem
-view.
-
-A captured criterion may be superseded only by authority outside
-execution-mutable state; the current workspace, its tests, and the agent itself
-cannot authorize supersession.
-
-Two gaps follow and are open, not decided: a build that reads `.git` makes VCS
-state VerificationRelevant while the scan skips it, and on Windows a symlink out
-of the workspace is neither observed nor protected. Closing either means
-widening observation or narrowing writability — never widening what a check is
-taken to prove.
-
-## Sandbox dimensions
-
-`HostProtected` above is the delivery-level abstraction. Sandbox policy refines
-it into three independent protection dimensions. Their separation is empirical:
-measured bypasses showed that protection on one dimension cannot be assumed to
-imply protection on another.
-
- **Integrity** — what host state may be mutated. Expressed by write roots.
- **Confidentiality** — what host information may be observed. Expressed by
-  `ForbidReadRoots`.
- **Authority** — what host capabilities may be exercised *without* possessing
-  their secrets. Expressed by `HostAuthorities`.
-
-`ReadOnly` is therefore an Integrity property only; it makes no Confidentiality
-or Authority claim.
-
-Network transport and host authority are independent even when a backend
-primitive conflates them: on macOS, `(deny network*)` also cut ssh-agent, so one
-flag could not express "no internet, still sign".
-
-Filesystem visibility is not authority: denying `file-read*` on a socket did not
-stop a connect. Possession is not authority: the key can be unreadable while an
-agent still signs with it.
-
-A protection claim exists only where a backend has a demonstrated enforcement
-primitive for that dimension. Unsupported dimensions stay explicitly unsupported,
-because a claim that outruns its enforcement is worse than an absent one: it is
-believed.
-
-Windows enforces Integrity on file creation only, when the user turns it on.
-Deletion and rename, Confidentiality and Authority (the named pipes of ssh-agent
-and docker, COM and RPC services) are not enforced there.
-
-**Known unmeasured surface — macOS host-mediated delegation:** Apple Events and
-Mach-service lookup are not denied by the current allow-default profile. Prior
-`osascript` and `launchctl submit` probes were inconclusive; no delegation
-effect has been demonstrated. This surface is outside the currently governed
-host-authority endpoint set.

-# Security Policy
-
-## Supported Versions
-
-Reasonix security fixes are prioritized for the currently developed Go rewrite
-and the current 1.x release line.
-
-| Version or branch | Security support |
-| --- | --- |
-| `main-v2` / 1.x releases | Supported |
-| `v1` / 0.x legacy branch | Critical fixes only, where practical |
-| Older releases, forks, or modified builds | Not covered unless the issue is reproducible upstream |
-
-If you are unsure whether a version is affected, report against the newest
-released 1.x version and include the exact version or commit you tested.
-
-## Reporting a Vulnerability
-
-Please report security issues privately. Do not open a public issue with exploit
-details, secrets, crash dumps, or proof-of-concept payloads.
-
-Preferred reporting path:
-
-1. Use GitHub private vulnerability reporting for this repository, if available.
-2. If private reporting is not available to you, open a minimal public issue
-   asking for a private maintainer contact path. Do not include exploit details
-   in that issue.
-
-Please include:
-
- Affected Reasonix version, commit, operating system, and installation method.
- The feature or surface involved, such as CLI, desktop app, HTTP `serve`, bot
-  gateway, MCP plugin, built-in tool, updater, or configuration loading.
- Clear reproduction steps using dummy credentials and non-sensitive files.
- The expected impact, such as secret disclosure, arbitrary file access,
-  command execution, sandbox escape, authentication bypass, or supply-chain risk.
- Any relevant logs with API keys, tokens, local paths, and personal data
-  redacted.
-
-Do not send real provider API keys, bot credentials, OAuth tokens, private
-workspace files, or third-party user data.
-
-## Security Boundaries
-
-Reasonix is a local coding agent. Many features intentionally operate on the
-user's local machine and workspace, including file reads, file writes, shell
-commands, MCP plugins, language servers, bot sessions, and model-provider
-requests. A finding is security-relevant when it crosses a supported boundary or
-bypasses an explicit guard.
-
-Supported boundaries include:
-
- Workspace confinement for file operations that are documented or implemented
-  as workspace-scoped.
- Permission checks for tool calls, shell commands, file writes, and approvals.
- Sandbox behavior for built-in shell execution where the platform supports it.
- Secret handling for provider keys, bot credentials, OAuth tokens, plugin
-  headers, and credential-store fallback files.
- HTTP `serve` protections, including the default per-launch token, the launch
-  token every state-changing request requires when authentication is opted
-  out, localhost binding assumptions, JSON-only state-changing requests, and
-  CORS restrictions.
- Desktop and bot session isolation, including per-workspace session metadata
-  and configured bot allowlists.
- Updater, install, and release verification paths.
-
-The following are normally treated as trusted local/operator-controlled inputs
-unless another bug lets an untrusted actor supply them:
-
- CLI arguments and text typed directly by the local user.
- The user's own configuration under the Reasonix home directory.
- Explicit `@path` references supplied by the local user to attach local files.
- MCP servers, language servers, hooks, and slash commands installed, enabled,
-  or approved by the local user.
- Provider base URLs and model names configured by the local user.
-
-The following can be security issues when reachable by an untrusted actor or
-when they bypass the intended boundary:
-
- Reading or writing files outside the configured workspace without explicit
-  local-user intent.
- Following symlinks or path traversal to escape workspace confinement.
- Running shell commands or external tools without the required permission gate.
- Leaking credentials, environment variables, prompt history, local files, or bot
-  messages to logs, model providers, MCP servers, crash reports, or telemetry.
- Allowing a website to drive the local HTTP server through CSRF, CORS, or
-  content-type bypasses.
- Letting a bot user outside the configured allowlist submit prompts, approve
-  tools, or access a project workspace.
- Trusting unverified update artifacts, plugin definitions, or downloaded
-  binaries.
-
-## Project Configuration
-
-Files that arrive with a workspace are untrusted input: `reasonix.toml`,
-`.reasonix/settings.json`, `.mcp.json` and the project `.env`. Cloning a
-repository is not a decision to trust its author, so these files may narrow
-what the user configured and never widen it.
-
-| Setting | What a workspace file may do |
-| --- | --- |
-| `sandbox.bash` | Move `off` to `enforce`, never back |
-| `sandbox.network` | Move `true` to `false`, never back |
-| `sandbox.forbid_read`, `sandbox.denied_domains` | Add to the user's lists |
-| `sandbox.allow_write`, `sandbox.workspace_root` | Apply only when they resolve inside the workspace, symlinks followed; `${VAR}` in any sandbox path expands from the process environment only |
-| `sandbox.host_authorities`, a user's `sandbox.allowed_domains` | Nothing |
-| `permissions.deny`, `permissions.ask` | Add to the user's rules |
-| `permissions.mode`, `permissions.allow`, `permissions.allow_dynamic_bash` | Nothing |
-| `desktop.default_tool_approval_mode` | Nothing |
-| `[network]` proxy settings | Nothing |
-| `[[providers]]`, `tools.system_one` endpoints | Declare them; they stay out of use until approved, and model settings naming them fall back to the user's |
-
-An "always allow" answer, or extra write access, granted in a workspace is
-stored under the Reasonix home, not in the workspace.
-
-Programs a workspace names for the host to run stay off until the user
-approves them for that workspace:
-
- Hooks, language server commands, `tools.search.rg_path`,
-  `tools.shell.path`, `[browser]` and `tools.system_one.laya.python` are
-  approved with `reasonix trust`, or for hooks by saving them from the hooks
-  editor.
- An approval is stored under the Reasonix home with a digest of the
-  declaration and of the workspace files it names; any change needs approval
-  again. Approvals and grants belong to one workspace folder.
- Hooks and language servers are checked against their approval again before
-  each start, and refused if a file they name changed, appeared or now
-  resolves elsewhere.
- A single program path (`tools.shell.path`, `tools.search.rg_path`,
-  `[browser]`, `laya.python`) may not point into the workspace, an
-  `allow_write` root, a temporary directory or a toolchain cache the bash jail
-  leaves writable, and may not climb with `..`; its approval covers the
-  program file's content.
- `tools.system_one.laya.local` is read from the user's configuration only.
- Without an interactive frontend they stay off.
- MCP servers a workspace declares stay off until the user enables them for
-  that workspace.
-
-A project value that is not applied is reported as a load warning with the
-reason. A way for workspace files to widen any of the above without the
-user's approval is a security issue.
-
-## `@` File References
-
-Reasonix supports `@path` references so users can include local files and images
-in a prompt. This is intentional local functionality, but implementations must
-preserve these invariants:
-
- In workspace-scoped sessions, relative and absolute paths must resolve under
-  the active workspace root before file content is read or attached.
- Path traversal such as `..` must not escape the workspace root.
- Symlinks must not be usable to bypass the intended workspace boundary.
- Unscoped local CLI compatibility must not be exposed to remote, bot, or
-  browser-controlled inputs unless an equivalent workspace boundary is applied.
- File content should be size-limited and binary content should not be dumped as
-  prompt text.
-
-Static analysis alerts about path expressions should be triaged against these
-rules: user-controlled path data is expected, but the access must either stay
-inside the configured workspace or be clearly limited to trusted local CLI use.
-
-## Out of Scope
-
-The following reports are usually out of scope unless they demonstrate a bypass
-of one of the boundaries above:
-
- A local user intentionally asks Reasonix to read, edit, or send their own
-  files to a configured model provider.
- A local user installs or enables a malicious MCP server, hook, slash command,
-  language server, or shell command and then grants it permission.
- A configured model provider, proxy, or MCP server receives data the user
-  intentionally sent to it.
- Denial-of-service issues that only affect the local user's own session and do
-  not corrupt files, leak secrets, or bypass permissions.
- Issues requiring administrator/root access on the user's machine before
-  interacting with Reasonix.
- Vulnerabilities in third-party services, models, proxies, or plugins that are
-  not caused by Reasonix behavior.
-
-## Coordinated Disclosure
-
-This is a community-maintained project. Maintainers will make a best-effort
-assessment, ask follow-up questions when needed, and coordinate fixes before
-public disclosure for confirmed vulnerabilities.
-
-Please give maintainers reasonable time to investigate and release a fix before
-publishing exploit details. If you plan to disclose on a timeline, include that
-timeline in your initial report.

-# Reasonix Mobile — the Android shell
-
-Runs Reasonix as an Android app: the kernel ships inside the APK and starts on the
-device, the interface is the same `desktop/frontend-next` build the desktop Studio
-serves, and the agent reaches servers over SSH.
-
-This file is for people building it. What a person installing it needs — what it
-does, how to pair with a computer, what it cannot do — belongs in the release
-notes.
-
-## One command
-
-```bash
-./scripts/build.sh release     # or debug
-```
-
-Three steps, in this order:
-
-1. `build-kernel.sh` → `app/src/main/jniLibs/arm64-v8a/libreasonix.so`
-2. `sync-page.sh` → `app/src/main/assets/page/`
-3. `./gradlew assembleRelease`
-
-Output: `app/build/outputs/apk/release/app-release.apk`
-
-The kernel and the page are **inputs to packaging, not Gradle build steps**.
-Running `gradle assembleRelease` on its own fails on purpose and names the script
-that produces whichever input is missing (`requireBuildInputs` in
-`app/build.gradle`): an APK with no kernel in it should not be buildable by
-accident.
-
-## Requirements
-
-| Component | Version |
-| --- | --- |
-| JDK | 21 (17 also works) |
-| Android SDK | `platforms;android-35`, `build-tools;35.0.0`, `platform-tools` |
-| Gradle | the committed wrapper, 8.14.3 (for AGP 8.11.1) |
-| Go | 1.26+ |
-| Node / pnpm | Node 24+ / pnpm 10 |
-
-```bash
-export ANDROID_HOME="$HOME/Android/Sdk"
-export ANDROID_SDK_ROOT="$ANDROID_HOME"
-export JAVA_HOME="/path/to/jdk-21"
-export PATH="$PATH:$(go env GOPATH)/bin"
-```
-
-`ANDROID_HOME` is the one thing nothing sets for you.
-
-## Scripts
-
-| Script | What it does |
-| --- | --- |
-| `build.sh [debug\|release]` | The whole chain |
-| `build-kernel.sh` | Cross-compiles the kernel only (`GOOS=android GOARCH=arm64 CGO_ENABLED=0`) |
-| `sync-page.sh` | Builds the frontend, copies `dist/` into assets, copies `LICENSE` |
-| `verify-page.sh` | **No phone needed**: starts the real kernel against the packaged page |
-| `run.sh [debug\|release]` | `adb install`, launch, follow the log |
-
-`verify-page.sh` is the one to run after a change: it starts the kernel with the
-same arguments `Kernel.kt` uses (`--auth token`, `--token-file`, `--port-file`,
-`-page`) and checks that it binds a port and answers 200. Without a device, that
-is as deep as the chain can be verified.
-
-## Where the code is
-
-| File | Owns |
-| --- | --- |
-| `MainActivity.kt` | The WebView, the back gesture, downloads, external links, renderer restart |
-| `Kernel.kt` | Unpacking the page, starting and stopping the kernel, waiting for the port, health probes, logs, the workspace directory |
-| `KernelService.kt` | The foreground service that keeps a long turn alive |
-| `NativeBridge.kt` | `@JavascriptInterface`: what the page may ask the phone for |
-| `BrowserShellServer.kt` | Loopback HTTP server the kernel's browser tools drive the overlay WebView through |
-| `Downloader.kt` | Writing a kernel-produced file through the system document picker |
-
-The page reaches the shell through `window.reasonixHost` and `ReasonixNative`,
-defined in `desktop/frontend-next/src/port/host.ts` (`AndroidHost`).
-
-**Phone and desktop share one page build.** What differs only on a phone is
-decided at runtime, not by a second set of components. `phoneShell()` in
-`src/port/host.ts` and the `[data-shell="android"]` selector in `mobile.css` both
-read `<html data-shell="android">`, which `index.html` sets before the bundle
-loads.
-
-One attribute feeding both is what keeps style and components from disagreeing
-about what a phone is.
-
-## What the page may ask the phone for
-
-`NativeBridge` is reachable from whatever document the WebView holds, so every
-method that touches the device asks `trusted()` first.
-
-The activity answers by comparing the **main frame's** origin against the
-kernel's and against the one paired computer the person scanned a code for. A
-page that navigated elsewhere is not trusted, even though it may still hold the
-object.
-
-Five methods answer without the check — `version`, `systemTheme`, `safeArea`,
-`setLayerOpen`, `setRunning` — because they report back what the page already
-knows about its own window and grant nothing.
-
-`openInApp(url)` is the pairing decision, not a navigation one: it loads a URL in
-this window only for the origin the scanner just returned, and only once.
-Without that, any page holding the kernel origin could hand itself the bridge.
-
-External links leave through the browser. A non-web scheme is routed to the
-system only for `mailto:` and `tel:`; everything else is dropped, because an
-`intent://` URL can start an arbitrary exported activity with caller-supplied
-extras.
-
-## Permissions, and what they cost
-
-`MANAGE_EXTERNAL_STORAGE` — opening a folder on the phone as a workspace. The
-kernel is a Go binary: it opens real paths with `open(2)`, and SAF hands back a
-`content://` URI it cannot open.
-
-Requested from the folder-picker action, never at launch. Android shows no dialog
-for it and opens system settings instead.
-
-**There is no OS-level sandbox around this kernel.** The PR sets the sandbox to
-off on Android, so confining the agent to the chosen folder is Reasonix's own
-write-root check and nothing else. A shell tool with all-files access can reach
-all shared storage.
-
-`REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` — Doze freezes the app group, which stops
-a turn that is still running. Asked once when a turn actually runs, never at
-launch, and the person can refuse. Refusing costs battery life during long turns
-and nothing else.
-
-**Google Play restricts this permission**: fine for a sideloaded build, a
-store-policy risk if this is ever listed.
-
-`FOREGROUND_SERVICE` / `FOREGROUND_SERVICE_DATA_SYNC` — keeping the kernel alive
-while the screen is off. `dataSync` is capped per 24 hours from Android 15. It is
-the closest honest description of "an agent is working".
-
-`CAMERA` — reading the pairing code a computer shows. Requested when the person
-asks to scan, never at launch. `ScanActivity` is not exported.
-
-`READ_EXTERNAL_STORAGE` / `WRITE_EXTERNAL_STORAGE` — the same folder walk below
-API 33. `maxSdkVersion`-gated; above 33 they are superseded by the permission
-above.
-
-`allowBackup=false` with explicit extraction rules, so a `keystore` or a token in
-app storage never leaves the device in a cloud backup.
-
-## Cleartext HTTP
-
-The kernel serves its page on `127.0.0.1:<port>`, and a paired computer serves
-the same page over its LAN address. Both are plain HTTP.
-
-Neither address can be written into a `network-security-config`: the port is
-chosen at start, the LAN address at scan time, and the format matches literals
-and domains, not subnets.
-
-So the config permits cleartext and the boundary is in the code instead.
-`shouldOverrideUrlLoading` sends every other http(s) origin to the browser, and
-the bridge answers only the kernel and the just-paired computer. A plaintext page
-on the LAN cannot become the document holding the bridge.
-
-## What goes into the APK
-
-| Content | Size | Why it is shaped this way |
-| --- | --- | --- |
-| `lib/arm64-v8a/libreasonix.so` | 45 MB | Go static binary, stripped. It is a `.so` rather than a file in `assets/` because only `nativeLibraryDir` is guaranteed executable — a binary copied to app storage fails on a device whose data partition is mounted `noexec`. |
-| `assets/page/` | 14 MB | The frontend build, including the Inter and Noto Sans SC fonts, `noCompress` |
-| `assets/LICENSE` | 1 KB | The repository's MIT licence, verbatim. MIT requires the notice and the licence text to accompany a binary distribution. |
-
-`assets/LICENSE` is generated by `sync-page.sh` from the repository's root
-`LICENSE`, not committed a second time: a checked-in copy drifts when the root
-file is updated.
-
-It sits in `assets/` rather than `assets/page/` because that directory is removed
-and rebuilt on every build.
-
-A release APK is about 31 MB.
-
-## Building
-
-**The Gradle wrapper is committed**, jar and all. `build.sh` refuses to run
-without `gradlew` rather than generating one from whatever `gradle` is on `PATH`:
-the dependency versions are part of the build.
-
-`gradle-wrapper.properties` pins `distributionSha256Sum`, so a mirror that serves
-a different distribution zip fails verification instead of being unpacked and
-run. Dependency repositories are the official ones only — a mirror belongs in a
-user-level init script.
-
-**Signing.** A release with no key configured comes out **unsigned**
-(`app-release-unsigned.apk`) with a warning. It used to fall back to the debug
-key, which produced an artifact that looked shippable and was signed by a
-per-machine key nobody chose: it could not install over the previous build.
-
-Point the build at a real key by writing `keystore/keystore.properties`
-(`storeFile`, `storePassword`, `keyAlias`, and optionally `keyPassword`) or by
-setting the matching `REASONIX_KEYSTORE*` environment variables. Key material
-stays out of the repository and out of build logs.
-
-Debug builds always use the debug key. Signing a debug build with the release key
-would let anyone who can read the keystore produce a build that installs over the
-shipped one under the same signature.
-
-**Non-ASCII checkout paths.** AGP refuses to build under a path with non-ASCII
-characters on Windows unless `android.overridePathCheck=true` is set. That is a
-property of one machine's disk layout, not of this project, so it is not in the
-repository's `gradle.properties`.
-
-Set it in a user-level `~/.gradle/gradle.properties` or pass
-`-Pandroid.overridePathCheck=true`.

- * The kernel's browser, as a loopback HTTP server.
- *
- * The Go kernel (`internal/platform/browser/shell.go`) drives a WebView by
- * POSTing JSON to a handful of paths on 127.0.0.1. This class is the other end
- * of that conversation: it accepts connections on a random port, parses the
- * minimal HTTP the kernel sends, and translates each path into an operation on
- * the overlay WebView.
- *
- * The server is deliberately tiny — no connection pooling, no keep-alive, no
- * chunked encoding — because the kernel is its only client and sends one
- * request per connection. A `ServerSocket` accept loop on a daemon thread is
- * the whole transport; each request is handled synchronously on its own thread.
- *
- * WebView operations must run on the UI thread. Each handler posts to the main
- * looper and waits on a latch, with a timeout that bounds the worst case (a
- * page that hangs the JS thread) to something the kernel's own 30-second client
- * timeout will not outlast.
- *
- * Memory note on `/screenshot`: a full-page `WebView.draw` into an ARGB_8888
- * bitmap at device resolution can reach tens of MB for a long page. The bitmap
- * is downsampled by a factor of 2 in each dimension before PNG encoding, which
- * keeps the peak allocation under ~10 MB for a typical 1080p viewport. The
- * original is recycled immediately after the downsample.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

-#
-# Why a shell script and not a Gradle task: the kernel is a Go module that lives
-# outside this Gradle build, with its own toolchain version pinned in go.mod. A
-# Gradle task that invoked `go build` would make the Android build depend on a Go
-# toolchain being configured for it, and would rebuild a 21MB binary on every
-# `assembleDebug` even when nothing in the kernel changed. This runs when you
-# mean it to, and the APK task only checks that the result is there.
-#
-# Output: app/src/main/jniLibs/arm64-v8a/libreasonix.so
-#   The name is not cosmetic. Android extracts files under `jniLibs/` to
-#   `nativeLibraryDir` and permits execution *there*; a binary shipped in
-#   `assets/` would have to be copied to app storage and chmod'd, which fails on
-#   a device whose data partition is mounted noexec. `lib*.so` is the shape the
-#   packager recognises as a native library, so the kernel wears it.
