feat(sdk): implement GJC SDK wire transport with WebSocket support

- Add error types and error code enumerations
- Implement frame types for SDK wire protocol (FrameType enum)
- Create Frame struct with JSON serialization/deserialization
- Implement SdkTransport with async WebSocket connection handling
- Support request/response correlation via request IDs
- Handle frame parsing and routing with background task
- Add comprehensive unit tests for frame creation and correlation
- Implement proper async handling with tokio and futures

Implements protocol version 3 with:
- Token-based authentication via query parameter
- Frame size limits (4 MiB max payload)
- Request timeout handling
- Proper error propagation and correlation

+## OVERVIEW
+Claw Code: public Rust implementation of the `claw` CLI agent harness (Claude-Code-style). Canonical code lives in `rust/`; the repo is an agent-managed exhibit (harnesses plan/execute/verify per README), not a hand-operated product. `src/` is a companion Python porting/parity workspace, not production code.

+
+## CONVENTIONS
+- `unsafe_code = "forbid"` workspace-wide; every crate opts in via `[lints] workspace = true`; clippy all=warn, pedantic=allow
+- Edition 2021, resolver 2, publish=false; no rust-toolchain pin (CI floats stable); no rustfmt.toml/clippy.toml — stock defaults
+- Giant flat files by design (main.rs 19.8k, tools/lib.rs 10.9k, commands/lib.rs 7.2k): organization is positional — types → spec table → dispatch → handlers → tests at EOF
+- Dual output paths everywhere: `render_x` + `render_x_json`; JSON errors to **stdout**, text errors to **stderr**
+- Tests: inline `#[cfg(test)] mod tests` primary; integration tests spawn `CARGO_BIN_EXE_claw` subprocess against mock-anthropic-service; tempfile everywhere; env-mutating tests serialize via env_lock/test_env_lock
+- Comments carry issue numbers (#824, #146); gate tests named by roadmap gate (g004_conformance.rs)
+- Python side: stdlib only, `python -m unittest`; src/ mixes camelCase (QueryEngine.py) and snake_case filenames
+
+## ANTI-PATTERNS (THIS PROJECT)
+- NEVER `cargo install claw-code` — crates.io stub is deprecated and installs `claw-code-deprecated.exe`; build from source
+- Forbidden doc strings (CI-enforced by .github/scripts/check_doc_source_of_truth.py): old org links `github.com/Yeachan-Heo/claw-code`, `github.com/code-yeongyu/claw-code`, `discord.gg/6ztZB9jvWq`, `assets/clawd-hero.jpeg`
+- Deprecated config keys: `permissionMode` → `permissions.defaultMode`; `enabledPlugins` → `plugins.enabled`; env `RUSTY_CLAUDE_PERMISSION_MODE` is dead
+- Direct push to main is policy-blocked (`main_push_forbidden` approval scope)
+- Automation lanes must not merge/close remote PRs/issues (docs/anti-slop-triage.md)
+- `claw init` must not scaffold `dontAsk` permission mode (regression-pinned in output_format_contract.rs)
+- File-level `#![allow(dead_code)]` blocks (main.rs, session_control.rs) are tolerated legacy — do not extend the pattern
+
+## UNIQUE STYLES
+- Dogfood build: scripts/dogfood-build.sh injects GIT_SHA; `claw version` provenance must equal HEAD
+- Mock parity: rust/mock_parity_scenarios.json drives CLI subprocess vs MockAnthropicService
+- Dogfooding uses `CLAW_CONFIG_HOME=$(mktemp -d)` for config isolation
+- Env contracts: GIT_SHA (build), CLAW_CONFIG_HOME (config dir), OLLAMA_HOST (provider override), `*_API_KEY`/`*_BASE_URL` per provider
+
+## COMMANDS
+```bash
+scripts/fmt.sh --check                 # fmt check (apply: scripts/fmt.sh)
+cd rust && cargo clippy --workspace --all-targets -- -D warnings
+cd rust && cargo test --workspace
+cd rust && cargo build -p rusty-claude-cli   # binary: rust/target/debug/claw
+python -m unittest discover -s tests   # Python suite
+python .github/scripts/check_doc_source_of_truth.py && scripts/roadmap-check-ids.sh   # docs/roadmap CI
+```
+
+## NOTES
+- `claw` binary comes from crate `rusty-claude-cli` (package/bin name mismatch)
+- rust-ci.yml triggers only on rust/**, docs/**, listed meta file changes (path filters)
+- CI clippy job runs without `-D warnings` — weaker than the documented gate; known pre-existing failures recorded in docs/g002/g003 maps
+- `claw acp` is a status stub, not a real ACP server
+- rust/ has committed harness dotdirs (.clawd-agents/, .omc/, .sandbox-home/) — intentional

+- Multi-provider support: Anthropic Claude, OpenAI, X.AI Grok, and OpenAI-compatible providers (Ollama, llama.cpp, vLLM)
+- 55 built-in tools: Bash, file I/O, editing, search, web access, agent delegation, and more
+- 120+ slash commands for configuration, help, and system operations
+- Permission system with support for workspace-write, read-only, and prompt-mode enforcement
+- Plugin system with manifest-driven plugin installation and management
+- Comprehensive session management with configuration loading and persistence
+- Dogfood build with build-time git provenance tracking
+
+### Fixed
+
+- Fixed duplicate assistant text in message rendering
+- Fixed Windows workspace path compatibility (support for multiple Windows path spellings)
+- Fixed session_id path traversal vulnerability in session store
+- Fixed untrusted project hooks in read-only mode
+- Fixed permission privilege ladder to use explicit rank ordering
+- Fixed Windows extended-path boundary handling
+- Fixed output ownership reporting on auto-compact retry paths
+
+### Changed
+
+- Reorganized permission system for improved clarity and consistency
+- Enhanced configuration system to support persistent provider configuration
+- Improved error handling and reporting throughout the runtime
+
+### Known Limitations
+
+- ACP / Zed integration is not yet implemented (status stub available via `claw acp`)
+- Python porting workspace is for reference only, not used in production
+
+## Pre-release
+
+This project has been in development as an agent-managed exhibit. Previous work is tracked in git history.

+> [!IMPORTANT]
+> **Claw Code is not the serious production project here.**
+> This repository is closer to a museum exhibit than a product pitch, a crustacean-run artifact kept alive by clawed gajaes, swept and labeled by agents, and automatically maintained according to the harnesses above.
+>
+> As already described in the project philosophy, this is not meant to be hand-operated like a normal product repo. It is an **agent-managed exhibit**: the harnesses plan, execute, verify, label, and preserve the artifact while the crabs keep the tank running.
+>
+> If you want to actually run work, start with **[LazyCodex](https://github.com/code-yeongyu/lazycodex)** or **[Gajae-Code](https://github.com/Yeachan-Heo/gajae-code)**. If you want to inspect the strange little fossil of the Claw Code moment, continue below.
+>

+> **Claw Code 在这里并不是一个严肃的生产级项目。**
+> 这个代码库更像是一个博物馆的展品，而不是一个产品推介。它是一个由螃蟹（crab）驱动的工件，由带爪子的 gajae（小龙虾）维持生命，由智能体清扫和贴标签，并根据上述的工具（harnesses）自动维护。
+>
+> 正如项目理念中所描述的，这并不旨在像普通产品代码库那样由人工操作。它是一个**由智能体管理的展品 (agent-managed exhibit)**：当螃蟹保持水箱运转时，工具会规划、执行、验证、标记并保存该工件。
+>
+> 如果你想要实际运行工作任务，请从 **[LazyCodex](https://github.com/code-yeongyu/lazycodex)** 或 **[Gajae-Code](https://github.com/Yeachan-Heo/gajae-code)** 开始。如果你想研究 Claw Code 时刻这个奇怪的小化石，请继续往下看。

+Claw Code 是 `claw` CLI 智能体工具的公开 Rust 实现。
+规范的实现位于 [`rust/`](./rust)，此代码库当前的事实来源是 **ultraworkers/claw-code**。
+
+> [!IMPORTANT]
+> 首先请阅读 [`USAGE.md`](./USAGE.md) 以了解构建、认证、CLI、会话和一致性工具（parity-harness）工作流。关于文件提交/导航问题，请参阅 [导航和文件上下文 (Navigation and file context)](./docs/navigation-file-context.md)。关于本地兼容 OpenAI 的模型和离线技能设置，请参阅 [本地兼容 OpenAI 提供商及技能设置 (Local OpenAI-compatible providers and skills setup)](./docs/local-openai-compatible-providers.md)。Windows 用户可以跳转至以 PowerShell 为主的 [Windows 安装和发布快速入门 (Windows install and release quickstart)](./docs/windows-install-release.md)。构建完成后，请首先使用 `claw doctor` 进行健康检查，查看 [`rust/README.md`](./rust/README.md) 获取 crate 级别的详细信息，阅读 [`PARITY.md`](./PARITY.md) 了解当前的 Rust 移植检查点，并查阅 [`docs/container.md`](./docs/container.md) 了解优先使用容器的工作流。
+>
+> **ACP / Zed 状态：** `claw-code` 尚未发布 ACP/Zed 守护进程或 JSON-RPC 入口点。请运行 `claw acp`（或 `claw --acp`）查看当前状态，而不是从源代码布局中猜测；`claw acp serve` 目前仅作为可发现性的别名，返回状态并以退出码 0 结束，真正的 ACP 支持仍在 `ROADMAP.md` 中单独追踪。有关公开的 JSON 契约，请参阅 [`docs/g011-acp-json-rpc-status-contract.md`](./docs/g011-acp-json-rpc-status-contract.md)。

+
+## 快速入门
+
+> [!NOTE]
+> [!WARNING]
+> **`cargo install claw-code` 会安装错误的东西。** crates.io 上的 `claw-code` crate 是一个已废弃的存根（stub），它会放置 `claw-code-deprecated.exe` — 而不是 `claw`。运行它只会打印 `"claw-code has been renamed to agent-code"`。**请勿使用 `cargo install claw-code`。** 请从源码构建（本代码库）或安装上游二进制文件：
+> ```bash
+> cargo install agent-code   # 上游二进制文件 — 安装为 'agent.exe' (Windows) / 'agent' (Unix)，而不是 'agent-code'
+> ```
+> 本代码库 (`ultraworkers/claw-code`) **仅支持从源码构建** — 请遵循以下步骤。
+
+```bash
+# 1. 克隆并构建
+git clone https://github.com/ultraworkers/claw-code
+cd claw-code/rust
+cargo build --workspace
+
+# 2. 设置您的 API 密钥（Anthropic API 密钥 — 不是 Claude 订阅）
+export ANTHROPIC_API_KEY="sk-ant-..."
+
+# 3. 验证所有配置是否正确
+./target/debug/claw doctor
+
+# 4. 运行提示词
+./target/debug/claw prompt "say hello"
+
+# 5. 启动交互式会话
+./target/debug/claw
+```
+
+> [!NOTE]
+> **Windows (PowerShell)：** 二进制文件是 `claw.exe`，而不是 `claw`。使用 `.\target\debug\claw.exe` 或运行 `cargo run -- prompt "say hello"` 以跳过路径查找。
+
+### Windows 设置
+
+**PowerShell 是一种支持的 Windows 路径。** 您可以使用任何适合您的终端 shell。Windows 上常见的入门问题是：
+
+1. **首先安装 Rust** — 从 <https://rustup.rs/> 下载并运行安装程序。完成后关闭并重新打开终端。
+2. **验证 Rust 是否在 PATH 中：**
+   ```powershell
+   cargo --version
+   ```
+   如果失败，请重新打开终端或运行 Rust 安装程序输出的 PATH 设置步骤，然后重试。
+3. **克隆并构建**（在 PowerShell、Git Bash 或 WSL 中均可）：
+   ```powershell
+   git clone https://github.com/ultraworkers/claw-code
+   cd claw-code/rust
+   cargo build --workspace
+   ```
+4. **运行**（PowerShell — 注意 `.exe` 和反斜杠）：
+   ```powershell
+   $env:ANTHROPIC_API_KEY = "sk-ant-..."
+   .\target\debug\claw.exe prompt "say hello"
+   ```
+
+有关发布版的 ZIP、PATH 设置、提供商切换以及通知的冒烟测试，请参阅 [`docs/windows-install-release.md`](./docs/windows-install-release.md)。
+
+**Git Bash / WSL** 是可选的替代方案，而非必须。如果您更喜欢 bash 风格的路径（例如 `/c/Users/you/...` 而不是 `C:\Users\you\...`），Git Bash（随 Git for Windows 一起提供）效果很好。在 Git Bash 中，`MINGW64` 提示符是预期的正常现象 — 并不代表安装已损坏。
+
+## 构建后操作：定位二进制文件并验证
+
+在 `claw-code/rust/` 中运行 `cargo build --workspace` 后，`claw` 二进制文件已构建，但**不会**自动安装到您的系统中。以下是定位文件和验证构建是否成功的方法。
+
+### 二进制文件位置
+
+`cargo build --workspace` 后，在 `claw-code/rust/` 目录中：
+
+**Debug 构建（默认，编译较快）：**
+- **macOS/Linux：** `rust/target/debug/claw`
+- **Windows：** `rust/target/debug/claw.exe`
+
+**Release 构建（已优化，编译较慢）：**
+- **macOS/Linux：** `rust/target/release/claw`
+- **Windows：** `rust/target/release/claw.exe`
+
+如果您运行 `cargo build` 时没有添加 `--release`，则二进制文件位于 `debug/` 文件夹中。
+
+### 验证构建是否成功
+
+直接使用其路径测试二进制文件：
+
+```bash
+# macOS/Linux (debug 构建)
+./rust/target/debug/claw --help
+./rust/target/debug/claw doctor
+
+# Windows PowerShell (debug 构建)
+.\rust\target\debug\claw.exe --help
+.\rust\target\debug\claw.exe doctor
+```
+
+无需实时凭据的 PowerShell 冒烟测试命令：
+
+```powershell
+$env:CLAW_CONFIG_HOME = Join-Path $env:TEMP "claw config home"
+New-Item -ItemType Directory -Force -Path $env:CLAW_CONFIG_HOME | Out-Null
+Remove-Item Env:\ANTHROPIC_API_KEY, Env:\ANTHROPIC_AUTH_TOKEN, Env:\OPENAI_API_KEY -ErrorAction SilentlyContinue
+.\rust\target\debug\claw.exe help
+.\rust\target\debug\claw.exe status
+.\rust\target\debug\claw.exe config env
+.\rust\target\debug\claw.exe doctor
+```
+
+如果这些命令成功执行，说明构建正常工作。`claw doctor` 是您的首个健康检查工具 — 它会验证您的 API 密钥、模型访问权限和工具配置。
+
+### 可选：添加到 PATH
+
+如果您希望在任何目录下都不用输入完整路径即可运行 `claw`，请选择以下方法之一：
+
+**选项 1：符号链接 (macOS/Linux)**
+```bash
+ln -s $(pwd)/rust/target/debug/claw /usr/local/bin/claw
+```
+然后重新加载 shell 并测试：
+```bash
+claw --help
+```
+
+**选项 2：使用 `cargo install` (所有平台)**
+
+构建并安装到 Cargo 的默认位置（`~/.cargo/bin/`，通常已在 PATH 中）：
+```bash
+# 在 claw-code/rust/ 目录下
+cargo install --path . --force
+
+# 然后在任何地方都可以运行
+claw --help
+```
+
+**选项 3：更新 shell 配置文件 (bash/zsh)**
+
+将此行添加到 `~/.bashrc` 或 `~/.zshrc`：
+```bash
+export PATH="$(pwd)/rust/target/debug:$PATH"
+```
+
+重新加载 shell：
+```bash
+source ~/.bashrc  # 或 source ~/.zshrc
+claw --help
+```
+
+### 故障排除
+
+- **"command not found: claw"** — 二进制文件在 `rust/target/debug/claw`，但未在您的 PATH 中。请使用完整路径 `./rust/target/debug/claw` 或按照上述方法进行软链接/安装。
+- **"permission denied"** — 在 macOS/Linux 上，如果缺少可执行权限（罕见情况），您可能需要运行 `chmod +x rust/target/debug/claw`。
+- **Debug vs. release** — 如果构建运行缓慢，说明您处于 debug 模式（默认）。在 `cargo build` 中添加 `--release` 以获得更快的运行时速度，但这会使构建本身花费 5-10 分钟。
+
+> [!NOTE]
+> **认证：** claw 需要一个 **API 密钥** (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY` 等) — 暂不支持 Claude 订阅登录作为认证途径。
+
+在验证二进制文件可运行后，执行工作区测试套件：
+
+```bash
+cd rust
+cargo test --workspace
+```

+# Issue #3283 Triage Summary
+
+**Issue:** docs: document OmniRoute OpenAI-compatible setup  
+**Opened by:** @diegosouzapw  
+**Status:** BLOCKED (waiting for clarification)  
+**Date:** 2026-10-13
+
+## Findings
+
+### Investigation
+1. Searched codebase for "OmniRoute" — **no matches found**
+2. Searched documentation (docs/local-openai-compatible-providers.md, MODEL_COMPATIBILITY.md) — **no mentions**
+3. Searched git history (commits, branches, PRs) — **no references**
+4. Checked GitHub API (rate limited, but issue title confirmed)
+
+### Current State
+- Issue #3283 is OPEN
+- No labels assigned
+- Title: "docs: document OmniRoute OpenAI-compatible setup"
+- This is a documentation request for setting up an OpenAI-compatible provider
+
+### Existing Documentation
+The repository already has comprehensive documentation for OpenAI-compatible providers:
+- `docs/local-openai-compatible-providers.md` — documents Ollama, llama.cpp, vLLM, and OpenRouter
+- `docs/MODEL_COMPATIBILITY.md` — model-specific provider routing details
+- `rust/crates/api/src/providers/openai_compat.rs` — provider implementation
+
+## Next Steps
+
+**Action taken:** Comment added to issue asking for:
+1. OmniRoute documentation/website link
+2. OpenAI-compatible endpoint example (base URL, API key format)
+3. Model ID examples
+4. Any special configuration or known quirks
+
+**Comment posted to:** https://github.com/ultraworkers/claw-code/issues/3283#issuecomment-6133484114
+
+## Conclusion
+
+**Cannot proceed without user input.** Once the user provides the necessary information about OmniRoute, the fix will involve:
+1. Adding a new section to `docs/local-openai-compatible-providers.md`
+2. Including setup example (environment variables, model names, basic smoke test)
+3. Following the existing format used for Ollama, llama.cpp, vLLM sections
+4. Creating a PR for review

+Global workspace override flags: `--cwd PATH`, `-C PATH`, and `--directory PATH` are accepted before any subcommand. They are validated before command dispatch and take precedence over the process `$PWD`; invalid paths return typed `invalid_cwd` JSON errors in JSON mode.
 
-- `read-only`
-- `workspace-write`
-- `danger-full-access`
+`--allowedTools` accepts canonical snake_case tool names (for example `read_file`, `glob_search`, `web_fetch`) plus documented aliases such as `read`, `glob`, `Read`, and `WebFetch`. `claw status --output-format json` exposes `allowed_tools.available` and `allowed_tools.aliases`, and invalid values return typed `invalid_tool_name` JSON with `tool_name`, `available`, and `tool_aliases`. A missing value before a subcommand or another flag returns `missing_argument` with `argument:"--allowedTools"`.
+
+`--output-format` accepts `text` or `json` case-insensitively and normalizes to the canonical lowercase modes. `CLAW_OUTPUT_FORMAT=json` sets the default output format for scripts, while an explicit `--output-format` flag takes precedence. Repeating the flag emits a stderr warning and JSON status envelopes expose `format_source`, `format_raw`, and `format_overridden` so composed flag arrays are auditable; invalid values return typed `invalid_output_format` JSON with `value` and `expected:["text","json"]`.
+
+Supported permission modes (default: `workspace-write`):
+
+- `read-only` allows inspection-only local tools such as file reads, glob/grep searches, local skills, and status-style reporting. It does not allow workspace mutation, network-fetch/search tools, or arbitrary command execution.
+- `workspace-write` is the safe default. It allows reads plus direct file-editing tools inside the current workspace, including write/edit/notebook/config/plan-mode updates, while still gating network-fetch/search tools, arbitrary shell execution, subagent launches, REPL subprocesses, and other full-access tools behind an explicit escalation.
+- `danger-full-access` allows every registered tool requirement, including arbitrary command execution, web fetch/search, subagent launches, subprocess REPLs, and unrestricted tool access. Select it only with an explicit `--permission-mode danger-full-access`, `--dangerously-skip-permissions`, `--skip-permissions`, env, or config opt-in.

+
+In addition to root instruction files such as `CLAUDE.md`, `CLAW.md`, `AGENTS.md`, `.claw/CLAUDE.md`, `.claude/CLAUDE.md`, and `.claw/instructions.md`, `claw` loads sorted Markdown/text rule files from:
+
+- `<repo>/.claw/rules/` (`.md`, `.txt`, `.mdc`) for shared project rules.
+- `<repo>/.claw/rules.local/` for personal local rules; this path is gitignored.
+
+Root instruction-file priority is `CLAUDE.md`, then `CLAW.md`, then `AGENTS.md` for each discovered directory. Discovery is bounded to the current git root when one exists, otherwise to the current directory only, so stale parent files outside the project do not silently bleed into the prompt. All loaded files contribute to the system prompt and to `status --output-format json` as `workspace.memory_files:[{path, source, origin, scope_path, outside_project, chars, contributes}]`; `claw doctor --output-format json` includes a `memory` check so automation can detect loaded and unexpected unloaded memory-file candidates without parsing prompt text.
+
+By default, `claw` also imports detected rules from common AI coding tools such as Cursor (`.cursorrules`, `.cursor/rules/`), GitHub Copilot (`.github/copilot-instructions.md`), Windsurf, Plandex, and Crush. Control this with `rulesImport` in any settings file:
+
+```json
+{
+  "rulesImport": "none"
+}
+```
+
+Use `"auto"` (the default) to import every supported framework, `"none"` to load only Claw instruction/rules files, or an array such as `["cursor", "copilot"]` to import selected frameworks.

-- For local servers, prefer the exact model ID reported by the server (`qwen3:latest`, `llama3.2`, `Qwen/Qwen2.5-Coder-7B-Instruct`, etc.). If your local gateway exposes slash-containing IDs, use that exact slug.

This covers LM Studio and llama.cpp server setups that register models under a plain `--alias`, not just Ollama-style tagged names (`llama3.2`, `qwen2.5-coder:7b`). `local/` is still needed only to preserve slash-containing IDs verbatim (e.g. Hugging Face repo IDs for vLLM/mlx-lm).
+- Against a remote/hosted OpenAI-compatible gateway (not local/private), Claw keeps the stricter `provider/model` or dot/colon-tag requirement so a mistyped bare name doesn't silently route to a paid hosted API.

+[OmniRoute](https://github.com/diegosouzapw/OmniRoute) is a third-party OpenAI-compatible AI gateway that can route requests to multiple providers. To use any remote OpenAI-compatible gateway with Claw, set `OPENAI_BASE_URL` to the gateway's `/v1` endpoint and provide your API key:
+
+```bash
+export OPENAI_BASE_URL="https://api.omniroute.ai/v1"
+export OPENAI_API_KEY="your-omniroute-api-key"
+claw --model "gpt-4" prompt "Reply exactly HELLO_WORLD_123"
+```
+
+To find the available model IDs on your gateway, use the `/models` endpoint:
+
+```bash
+curl -sS "$OPENAI_BASE_URL/models" \
+  -H "Authorization: Bearer $OPENAI_API_KEY" | jq '.data[].id'
+```
+
+For local configuration, see your gateway's documentation for the correct base URL, API key format, and available model IDs. The same OPENAI_BASE_URL + OPENAI_API_KEY pattern applies to any OpenAI-compatible remote gateway.

+# Asolaria for claw-code — a compact, tamper-evident wire format + addressing model for the agent event firehose
+
+A **self-contained, additive example** (no changes to claw-code core). It contributes one reproducible
+Rust benchmark plus a design write-up, aimed at the part of claw-code that moves the most bytes:
+**clawhip** — the event router that watches git commits, tmux sessions, GitHub PRs and agent-lifecycle
+events and pushes routing *out* of the agent context window so agents stay focused on implementation.
+
+The technique is from **Asolaria**, a multi-agent fabric built and operated *with* a claw-code-style
+autonomous harness. We contribute the parts that are (a) genuinely useful to a no-human-intervention
+harness and (b) **reproducible on your machine** — and we explicitly tag the parts that are
+architecture/vision, so nothing here backfires when an AI reviewer re-runs it.
+
+> **The bigger picture (tagged: vision/architecture, not a benchmark):** Asolaria's end goal is to make
+> *every device a surface* for one self-improving fabric — the device renders/addresses at ~0 local
+> token cost while the heavy reasoning is paged onto larger compute. You don't need to buy any of that
+> to use what's below; the wire format and 8-byte addressing stand on their own, measured.
+
+---
+
+## 1. The measured win (REPRODUCIBLE — re-run it)
+
+clawhip's event stream is high-rate and, today, JSON text. Re-encoding the same records as a
+fixed-width binary wire (`json=0`) and optionally folding a SHA-256 hash-chain over them gives, on
+**200,000** agent-lane-event records (measured; ratios are the reproducible part, ns vary by CPU):
+
+| Per record | JSON (text) | `json=0` binary | binary + SHA-256 chain |
+|---|---|---|---|
+| **Wire size** | 153.2 B | **33.0 B — 4.64× smaller** | **65.0 B — 2.36× smaller** |
+| **Encode** | ~307 ns | **~28 ns — ~11× faster** | binary + one hash |
+| **Decode** | ~468 ns (parse) | **~0.8 ns — decode ≈ free** | field read = pointer offset |
+| **Integrity** | none | none | **per-record tamper-evident** |
+
+- The lane is addressed by its **8-byte FNV-1a-64 handle**, so the lane string is never repeated;
+  fields are fixed-width little-endian, so decode is a pointer offset, not a parse.
+- The chain link is `link_n = SHA256(link_{n-1} ‖ record_n)`. It adds **exactly +32 B** → 65.0 B/rec,
+  and any insert / delete / reorder / single-bit edit breaks the fold from that record on; a one-pass
+  verify **localizes the first altered record** (the bundled bench demonstrates this).
+- **Honest nuance (not a compression claim):** `gzip` narrows the *raw-size* gap (crypto links are
+  high-entropy by design). The durable wins are **uncompressed wire size, decode speed, and
+  integrity** — the IPC / mmap / tail-replay path and a tamper-evident audit trail — not archival
+  compressibility.
+
+See [§6 Reproduce](#6-reproduce).
+
+---
+
+## 2. The addressing capacity (LOGICAL / CANON — address *space*, not materialized things)
+
+Asolaria addresses subsystems with **BEHCS-1024**: a radix-1024 glyph tuple over a **60-dimension**
+coordinate. One ~12-byte tuple names a whole subsystem (room / lane / agent) and rehydrates losslessly
+to its full ~6,184-byte descriptor *via the fabric store*.
+
+- **DERIVABLE (arithmetic):** the 12-byte wire handle alone is a **2⁹⁶ ≈ 7.9×10²⁸** namespace —
+  astronomically past any harness demand (a lifetime of events ≈ 10⁹–10¹²), so agents mint ids
+  independently with effectively zero collision risk and no coordinator.
+- **LOGICAL / CANON (do NOT re-run as a count):** the full 60-D space is `(1024⁶⁰)⁵⁰ ≈ 10⁹⁰³⁰` —
+  the address space the scheme can *name*, not a count of things that exist.
+- **Addressing, measured in-fabric (NOT reproduced by this example):** a ~12-byte glyph indexing its
+  ~6,184-byte descriptor is **520:1** — *addressing* (the tuple points into a store), **not** a codec
+  you can rehydrate from 12 bytes alone. We cite it; we do not claim the local bench reproduces it.
+
+> **Anti-overclaim:** 12 bytes do **not** enumerate 10⁹⁰³⁰ values (96 bits is ~10²⁸·⁹). The 10⁹⁰³⁰ is
+> the *scheme's* naming ceiling, not the wire handle's cardinality, and not a count of materialized
+> entities.
+
+---
+
+## 3. Per-component benefit to claw-code
+
+Tags mark which lines are re-runnable here vs architecture.
+
+- **8-byte FNV-1a-64 content-handle** [8-byte width MEASURED; content-addressing architecture] — a tmux
+  session name / `owner/repo#1204` / worktree path (30–120+ B) collapses to one fixed 8-byte handle
+  agents pass instead of prose; "did we already report this commit?" is an 8-byte equality check.
+  *(FNV-1a-64 is a non-cryptographic dedup/address hash — tamper-evidence is the SHA-256 chain's job.)*
+- **json=0 binary wire** [MEASURED §1] — 4.64× smaller, decode≈free for clawhip's high-rate event log;
+  fixed width → O(1) seek / tail-follow / byte-range replay (record N at offset `N*width`).
+- **BEHCS event envelope** [size/speed MEASURED; ordering architecture] — each event carries
+  `lane(8B) + seq + lamport + hash`; a stable total order `(lamport, lane, seq)` makes replay
+  deterministic across racing agents; a dropped event shows as a seq gap, a double-delivery as a dup.
+- **60-D tuple addressing** [§2] — reference a whole subsystem by a tiny handle instead of inlining a
+  descriptor clawhip just evicted; sibling lanes share a coordinate prefix (route a lane-family by
+  prefix, not an id list).
+- **SHA-256 hash-chain** [MEASURED §1/§6] — a no-human-intervention harness gets a tamper-evident audit
+  trail for +32 B/rec; the chain breaks on any mutation and a one-pass recompute localizes the first
+  bad record.
+- **Stubbed rooms as RAM** [handle MEASURED; demand-paging architecture/vision] — a "room" (open files,
+  prior reasoning, sub-task ledger) lives as an out-of-context descriptor stub keyed by an 8-byte
+  handle; only the needed slice hydrates into context. Footprint scales with *active* agents, not
+  total. *(Paging against larger compute is the architecture model, not a deployed cluster.)*
+
+---
+
+## 4. Concrete shape on the wire
+
+One BEHCS-enveloped clawhip event (65.0 B binary, chained):
+
+```
+lane    = 0xA3F1C2D4E5B60718   # 8-byte FNV-1a-64 handle for "executor-7/git-watch"
+seq     = 4271                 # per-lane monotonic: 4270->4272 = dropped; repeated 4271 = dup
+lamport = 98142                # deterministic cross-lane order, no wall clock
+rec     = <33 B fixed-width payload>          # vs 153.2 B as JSON
+link    = SHA256(prev_link ‖ rec)             # 32 B; editing any past rec breaks every later link
+```
+
+---
+
+## 5. Where this comes from
+
+Asolaria (public Host-8 lane — the council modules + this technique live here):
+**https://github.com/JesseBrown1980/asolaria-federation-1024**
+
+A multi-agent system built/operated with a claw-code-style autonomous harness. This PR contributes only
+the additive, reproducible slice.
+
+---
+
+## 6. Reproduce
+
+```bash
+cd examples/asolaria-wire
+cargo run --release
+```
+
+It will, with no network or external services:
+1. Generate **200,000** synthetic agent-lane-event records (the clawhip lane-event shape).
+2. Encode each as JSON text and as the `json=0` fixed-width binary; report **B/record** and **ns/record**
+   → expect ~**153.2 / 33.0 B** and the **4.64× size / ~11× encode / decode≈free** figures.
+3. Account the SHA-256 chain (+32 B/rec) → **65.0 B/rec (2.36×)**.
+4. Run the **tamper test**: flip one bit in record #5, re-fold the chain, and confirm the verifier
+   reports **record #5** as the first broken link.
+
+Absolute ns vary by CPU; the **ratios and the tamper-detection** are what to verify. Run `gzip` on the
+two wire forms yourself to confirm the honest nuance in §1.
+
+---
+
+## 7. Honesty self-check
+
+- **Reproducible (re-run them):** 153.2→33.0 B (4.64×), +32 B chain → 65.0 B (2.36×), ~11× encode,
+  decode≈free, and SHA-256 tamper-localization. (200k records; ratios are the portable part.)
+- **Derivable (arithmetic):** 2⁹⁶ ≈ 7.9×10²⁸ handle namespace.
+- **Logical / CANON (do NOT re-run as a count):** the 60-D BEHCS-1024 ceiling `(1024⁶⁰)⁵⁰ ≈ 10⁹⁰³⁰` —
+  address space, not entities. The 520:1 glyph↔descriptor figure is **addressing measured in-fabric**,
+  cited, **not** reproduced by this example.
+- **Architecture / vision (not benchmarked):** clawhip/MCP integration, Lamport ordering,
+  stubbed-rooms-as-RAM paging, every-device-as-surface. Presented as proposed mappings, not deployed
+  facts.
+- **Anti-marketing:** `gzip` closes the raw-size gap; the size win is uncompressed-wire + decode-speed +
+  integrity, never compressibility. FNV-1a-64 is non-cryptographic dedup, not security.

+- **Parity testing**: `mock_parity_scenarios.json` at workspace root, loaded via `CARGO_MANIFEST_DIR/../../mock_parity_scenarios.json`. Scripts in `scripts/` (`run_mock_parity_harness.sh`, `run_mock_parity_diff.py`).
+- **CI**: `.github/workflows/rust-ci.yml` (fmt, clippy, test, docs, Windows smoke) and `release.yml` (v* tag builds for linux-x64/macos-arm64/windows-x64).
+- **Committed test fixtures**: `.clawd-agents/`, `.omc/`, `.sandbox-home/` are checked-in harness dotdirs.
+- **Docs**: `PARITY.md`, `TUI-ENHANCEMENT-PLAN.md`, `README.md` alongside this file.
+
+## CONVENTIONS
+
+Workspace lints (all crates opt in via `[lints] workspace = true`):
+- `unsafe_code` = **forbid**. No exceptions.
+- clippy `all` = warn, `pedantic` = allow. Explicitly allowed: `module_name_repetitions`, `missing_panics_doc`, `missing_errors_doc`.
+
+No `rustfmt.toml` or `clippy.toml`. Stock defaults only.
+
+TUI rule: formatting fns take `&mut impl Write`, never stdout directly. Never mix raw ANSI escapes with crossterm.
+
+Library crates don't carry the `claw-` prefix. Binary crates do (except legacy `rusty-claude-cli`).
+
+Workspace version is `0.1.3`, `publish = false`, MIT license.
+
+No rust-toolchain file, no MSRV. CI pins `dtolnay/rust-toolchain@stable`.
+
+## ANTI-PATTERNS
+
+- Don't run `cargo fmt --manifest-path rust/Cargo.toml` from the repo root. Use `../scripts/fmt.sh` instead.
+- Don't add `unsafe` code. The lint is set to `forbid`, not `deny`. You can't `#[allow]` it.
+- Don't create dependencies from `commands` → `tools`. The arrow goes `tools` → `commands`.
+- Don't write TUI output directly to stdout or use raw ANSI escape sequences.
+- Don't add features to crates other than `claw-rag-service` without good reason; the workspace is feature-lean by design.
+
+## COMMANDS
+
+All run from `rust/`:
+
+```sh
+# Format (check only)
+../scripts/fmt.sh --check
+
+# Format (apply)
+../scripts/fmt.sh
+
+# Lint (strict, matches what you should pass before pushing)
+cargo clippy --workspace --all-targets -- -D warnings
+
+# Test
+cargo test --workspace
+
+# Build specific binary
+cargo build -p rusty-claude-cli
+cargo build -p claw-analog
+cargo build -p claw-rag-service
+cargo build -p mock-anthropic-service
+```
+
+Note: CI clippy runs without `-D warnings`, so the local check above is stricter than the gate.

 ## Model Aliases
 
-Short names resolve to the latest model versions:
+Short model aliases resolve to canonical model IDs. Because the router selects a
+provider from the resolved model, an alias also determines which backend and
+credentials are used — choose the alias for the provider you have an API key for.
+Alias resolution is case-insensitive (`OPUS` behaves the same as `opus`). Aliases
+are the bare short names listed below: a prefixed form such as `anthropic/opus`
+is not an alias, and is passed through as-is rather than expanded to
+`claude-opus-4-7`.
 
-| Alias | Resolves To |
-|-------|------------|
-| `opus` | `claude-opus-4-6` |
-| `sonnet` | `claude-sonnet-4-6` |

+| `kimi` | `kimi-k2.5` | DashScope (OpenAI-compatible) | `DASHSCOPE_API_KEY` |
+
+Anthropic aliases track the latest published model versions. xAI models honor
+`XAI_BASE_URL` and Kimi honors `DASHSCOPE_BASE_URL` for base-URL overrides. Alias
+resolution is implemented in `resolve_model_alias`
+([`crates/api/src/providers/mod.rs`](./crates/api/src/providers/mod.rs)); for

 `claw acp` is a local discoverability surface for editor-first users: it reports the current ACP/Zed status without starting the runtime. As of April 16, 2026, claw-code does **not** ship an ACP/Zed daemon or JSON-RPC entrypoint yet, and `claw acp serve` is only a status alias until the real protocol surface lands. Status queries exit 0 and expose the same machine-readable contract via `--output-format json`; malformed ACP invocations exit 1 with `kind: unsupported_acp_invocation`.
+`--output-format` accepts `text` or `json` in any casing. `CLAW_OUTPUT_FORMAT=json` selects JSON as the default for non-interactive commands, explicit flags override it, repeated flags warn on stderr, and status JSON exposes `format_source`, `format_raw`, and `format_overridden`. Help and doctor output also surface `CLAW_LOG` / `RUST_LOG` as the logging environment knobs.
+`claw version --output-format json` is the provenance probe for automation: it reports full `git_sha`, derived `git_sha_short`, `is_dirty`, `branch`, `commit_date`, `commit_timestamp`, `rustc_version`, runtime `executable_path`, and `binary_provenance`; the text report is available as `human_readable` instead of a duplicate `message` field.
+`status --output-format json` reports loaded project memory files under `workspace.memory_files[]` with each file's `path`, `source` (`claude_md`, `claw_md`, `agents_md`, or scoped/rule sources), `origin`, `scope_path`, `outside_project`, `chars`, and `contributes`; `claw doctor --output-format json` includes a dedicated `memory` check. Root instruction-file priority is `CLAUDE.md`, then `CLAW.md`, then `AGENTS.md`, discovery is bounded to the current git root when present (otherwise cwd only), and all non-duplicate loaded files contribute to the rendered system prompt.
+`claw mcp --output-format json` reports partial MCP config success: valid servers remain in `servers[]` while malformed siblings appear in `invalid_servers[]`, with `total_configured`, `valid_count`, and `invalid_count` split out for automation. `status` mirrors this as `mcp_validation`, and doctor includes an `mcp validation` check.
+`status --output-format json` also reports partial hook config success under `hook_validation`: valid hook entries are retained while malformed or unknown-event siblings appear in `invalid_hooks[]`, with `valid_count`, `invalid_count`, and typed `kind` fields (`invalid_hooks_config` or `unknown_hook_event`) for automation. `doctor --output-format json` includes a `hook validation` check, and `config --output-format json` includes `hook_validation` metadata with degraded status when invalid entries exist.
+Shorthand prompt mode honors the POSIX `--` end-of-flags separator, so `claw -- "-prompt-with-dash"` and unknown dash-prefixed non-flag text stay on the prompt path instead of being treated as CLI options.
+`claw dump-manifests` is self-contained: it emits the Rust resolver inventory for the selected workspace (commands, tools, agents, skills, and bootstrap phases) without requiring an upstream Claude Code TypeScript checkout. Use `--manifests-dir PATH` only to scope resolver discovery to another directory.

+## OVERVIEW
+
+LLM provider client layer: dispatches Anthropic, xAI, OpenAI, DashScope, and Ollama behind two wire protocols (Anthropic Messages native, OpenAI Chat Completions compat).
+
+## WHERE TO LOOK
+
+| Module | What lives here |
+|---|---|
+| `client.rs` | `ProviderClient` enum (facade). `from_model(model)` resolves alias, picks `ProviderKind`, handles OLLAMA_HOST and DashScope qwen-prefix cases. `send_message`/`stream_message`. |
+| `providers/mod.rs` | `Provider` trait (generic, dead_code-allowed, not used for dispatch). `ProviderKind`, `resolve_model_alias`, `ProviderMetadata` (auth_env, base_url_env, default_base_url), `max_tokens_for_model[_with_override]`, capability/diagnostic reporting, `preflight_message_request` validation. |
+| `providers/anthropic.rs` | `AnthropicClient` (re-exported as `ApiClient` at crate root). Dual auth: API key env vs saved OAuth (`AuthSource`, `OAuthTokenSet`, token expiry checks). Base-url resolution. SSE `MessageStream`. Prompt-cache hooks. |
+| `providers/openai_compat.rs` | `OpenAiCompatClient` parameterized by `OpenAiCompatConfig` (presets: `xai()`, `openai()`, `dashscope()`, `OLLAMA_CONFIG`). Heavy translation layer: `build_chat_completion_request`, `translate_message`, `sanitize_tool_message_pairing`, `flatten_tool_result_content`. Model-quirk predicates (`is_reasoning_model`, etc.). Body-size estimation/guards. |
+| `types.rs` | Provider-agnostic wire types: `MessageRequest`, `InputMessage`, `ContentBlock`, `StreamEvent`, `Usage`, `ToolDefinition`, `ToolChoice`. |
+| `sse.rs` | `SseParser`, `parse_frame`. |
+| `http_client.rs` | reqwest builders, `ProxyConfig` from env proxy vars, `TimeoutConfig`. |
+| `error.rs` | `ApiError`. |
+| `prompt_cache.rs` | `PromptCache` + `Stats` (Anthropic-only). |
+| `lib.rs` | Curated `pub use` lists define the public surface. Also re-exports sibling telemetry crate items. |
+
+## CONVENTIONS
+
+- Module-private by default. `lib.rs` `pub use` lists are the sole public API surface.
+- `#[must_use]` on pure constructors.
+- Provider config follows an env-var pair pattern: `*_API_KEY` / `*_BASE_URL`, recorded in `ProviderMetadata`.
+- Leaf files carry targeted `#![allow(clippy::cast_possible_truncation)]` where needed.
+- Dispatch goes through the `ProviderClient` enum, not trait objects. The `Provider` trait exists but is dead-code-allowed.
+- Streams unify into `MessageStream` with `next_event()` yielding `StreamEvent`.
+
+## TESTS
+
+- Four integration test files under `tests/`:
+  - `client_integration` — core client behavior
+  - `openai_compat_integration` — OpenAI-compat translation paths
+  - `provider_client_integration` — `ProviderClient` dispatch
+  - `proxy_integration` — proxy config
+- Tests that touch env vars serialize through a shared `env_lock()` mutex. Don't skip this or you'll get flaky parallel failures.
+- `benches/request_building.rs` is the workspace's only Criterion bench. Targets hot translation functions. This file bulk-opts out of strict lints.

+## OVERVIEW
+
+REPL slash-command surface: parsing, spec registry, help rendering, and a handful of in-crate handlers. Single flat `src/lib.rs` (~7k lines). Deps: `plugins`, `runtime`, `serde_json` only. Note: `tools` depends on `commands`, not the reverse.
+
+## lib.rs MAP
+
+| Lines | Landmark |
+|-------------|----------|
+| 16–58 | Registry types: `CommandManifestEntry`, `CommandSource` (Builtin / InternalOnly / FeatureGated), `CommandRegistry`, `SlashCommandSpec`, `SkillSlashDispatch` |
+| 60–1047 | `SLASH_COMMAND_SPECS` static table. 120+ entries (help, status, sandbox, compact, model, permissions, clear, cost, resume, config, mcp, memory, init, diff, version, bughunter, commit, pr, issue, ultraplan, teleport, debug-tool-call, export, session, plugin, agents, skills, doctor, plan, review, tasks, theme, vim, voice, chat, ...) |
+| 1048–1303 | `SlashCommand` enum (~65 variants + `Unknown(String)`), `SlashCommandParseError`, `SlashCommand::parse` (L1218) |
+| 1515–1899 | Per-command arg parsers: `parse_mcp_command`, `parse_plugin_command`, `parse_session_command`, etc. |
+| 1900–2108 | Help/suggestion rendering: `render_slash_command_help*`, `suggest_slash_commands` (Levenshtein), category grouping |
+| 2109–2682 | Result types + handlers: `handle_plugins_slash_command`, `handle_agents/mcp/skills_slash_command(_json)`, skill dispatch/resolve |
+| 3160–5293 | Reporting layer: paired text and `_json` renderers for plugins/agents/skills/mcp reports, skill install/uninstall/create-agent logic, frontmatter parsing, root discovery |
+| 5294 | `handle_slash_command(input, session, compaction)` top dispatch. Only Compact and Help execute here; all other variants return to the REPL caller |
+| 5403–7183 | `mod tests` (~1780 lines) |
+
+## ADDING A SLASH COMMAND
+
+1. **Spec.** Add a `SlashCommandSpec` entry to `SLASH_COMMAND_SPECS`. Set `resume_supported` honestly.
+2. **Enum + parse.** Add a variant to `SlashCommand`. Wire a match arm in `SlashCommand::parse`. If the command takes arguments, add a dedicated `parse_*_command` function in the arg-parser block.
+3. **Handler.** Decide where execution lives:
+   - In-crate (like Compact/Help): handle it inside `handle_slash_command`.
+   - Returned to caller: just return the parsed variant. The REPL layer executes it.
+4. **Help.** Make sure the spec's `summary` and `argument_hint` are set so help rendering and suggestion matching pick it up automatically.
+5. **Tests.** Cover parsing (valid input, bad input, edge cases) in the inline `mod tests`.
+
+## CONVENTIONS
+
+- **Dual renderers.** Every report surface has a text variant and a `_json` variant: `handle_x` / `handle_x_json`, `render_*` / `render_*_json`. Keep them in sync.
+- **Error style.** Handlers return `std::io::Result`. Parse failures use `SlashCommandParseError`.
+- **Manifest registries.** Pattern is `entries: Vec<_Entry>` backed by the static spec table.
+- **Dependency direction.** This crate knows nothing about `tools`. Don't import it.
+- **No execution here.** Almost all commands pass through as parsed data. Only Compact and Help run inside this crate. Respect that boundary.

+///
+/// It is what a provider that dies on the socket actually looks like, and it
+/// keeps the failure in a *later* parser call than the answer text. The whole
+/// response is one `write_all` on the mock's side, so a complete trailing frame
+/// would land in the same read chunk as the deltas — and `SseParser::push`
+/// returns `Err` from inside its frame loop, which discards the events it had
+/// already parsed from that same chunk. The client would then never render the
+/// text at all, and the scenario would be exercising that parser behaviour
+/// instead of the terminal state it is meant to reproduce. A truncated tail
+/// stays in the parser's buffer, so `push` returns the deltas normally and the
+/// failure only surfaces from `finish()`, once the client has consumed every
+/// event ahead of it.

+/// The failure is a frame that does not deserialize — `api::types::StreamEvent`

+
+## OVERVIEW
+
+Plugin subsystem: how third-party, builtin, and bundled tools/commands/hooks enter the runtime.
+
+## WHERE TO LOOK
+
+- `src/lib.rs` (~3,863 lines): the bulk of the crate. Manifest parsing (`.claude-plugin/plugin.json`), installed-plugin registry, lifecycle model, permission model, install/update management.
+- `src/hooks.rs`: hook event model (`HookEvent`, `HookRunResult`) and `HookRunner` for shell-hook execution. Re-exported from `lib.rs`. **Caution:** the runtime crate has its own `hooks.rs` with a separate `HookRunner` (execution + abort-signal side, around L155). Know which layer you need before editing.
+- `src/test_isolation.rs`: test isolation helpers.
+- `bundled/`: example plugin fixtures. `example-bundled/` and `sample-hooks/` each contain `.claude-plugin/plugin.json` plus `pre.sh`/`post.sh` shell hooks. Treat these as the reference shape when authoring a new plugin.
+
+## CONVENTIONS
+
+**Key public types** (all in `src/lib.rs` unless noted):
+
+- Kinds/definitions: `PluginKind`, `PluginDefinition`, `BuiltinPlugin`, `BundledPlugin`, `ExternalPlugin`.
+- Manifests: `PluginManifest`, `PluginToolManifest`, `PluginToolDefinition`, `PluginToolPermission`, `PluginCommandManifest`.
+- Hooks: `PluginHooks`, `HookEvent`, `HookRunResult` (from `hooks.rs`).
+- Lifecycle/permissions: `PluginLifecycle`, `PluginPermission`.
+- Registry: `InstalledPluginRecord`, `InstalledPluginRegistry`, `RegisteredPlugin`, `PluginRegistry` (+ `Report`, `Summary`, `LoadFailure`).
+- Management: `PluginManager` (+ `Config`), `InstallOutcome`, `UpdateOutcome`.
+- Trait: `Plugin`.
+- Errors: `PluginError`.
+- Entry points: `builtin_plugins()`, `load_plugin_from_directory()`.
+
+**Lifecycle spans two crates.** Manifest parsing and registry live here. Health checks, degraded-mode, and `PluginState` live in `runtime/src/plugin_lifecycle.rs`. Changes to plugin lifecycle logic often touch both.
+
+**Plugin shape.** A plugin directory contains `.claude-plugin/plugin.json` at minimum. Shell hooks (`pre.sh`, `post.sh`) sit alongside. See `bundled/` for working examples.
+
+**Consumers.** `PluginManager` has ~48 references across the workspace. CLI wires plugins via `RuntimePluginStateBuildOutput` in `rusty-claude-cli`. The tools crate exposes plugin tools through `GlobalToolRegistry`.
+
+## NOTES
+
+- Don't confuse the two `HookRunner` implementations. This crate's version handles the event model. The runtime crate's version handles execution and abort signals.
+- `lib.rs` is large. Most searches for plugin behavior start and end there.
+- Bundled plugin fixtures under `bundled/` are used in tests. Breaking their structure breaks CI.
+- Permission model is enforced at install time and checked at runtime. Both paths matter when modifying `PluginPermission`.

+# AGENTS.md — runtime crate
+
+## OVERVIEW
+
+Core crate of `claw`: session persistence, permissions, prompt assembly, MCP plumbing, tool-facing file ops, conversation loop. 47 flat modules in src/, ~330 pub symbols, ~170 re-exported flat from lib.rs.
+
+## WHERE TO LOOK
+
+| Group | Files | Entry points |
+|---|---|---|
+| session/conversation | session.rs, session_control.rs, conversation.rs, compact.rs, summary_compression.rs, usage.rs | `Session` (L117), `SessionStore`, `ConversationRuntime` (L130), `ApiClient`/`ToolExecutor` traits |
+| config | config.rs, config_validate.rs, bootstrap.rs | `ConfigLoader` (L409), type-export heaviest file; MCP server config enums live here |
+| MCP (6-file split) | mcp.rs, mcp_client.rs, mcp_stdio.rs, mcp_server.rs, mcp_tool_bridge.rs, mcp_lifecycle_hardened.rs | `McpServerManager` (L488 in mcp_stdio.rs), JSON-RPC spawn |
+| hooks/plugins | hooks.rs, plugin_lifecycle.rs | `HookRunner` (L155), abort signal, healthcheck, degraded mode |
+| permissions/safety | permissions.rs, permission_enforcer.rs, policy_engine.rs, approval_tokens.rs, sandbox.rs, bash_validation.rs, trust_resolver.rs | `PermissionEnforcer` (L27), `GreenLevel`, lane decisions |
+| tools/execution | bash.rs, file_ops.rs, lsp_client.rs | `execute_bash`, `*_in_workspace` file op variants |
+| lane/worker | lane_events.rs, worker_boot.rs, task_packet.rs, task_registry.rs, team_cron_registry.rs, branch_lock.rs, stale_base.rs, stale_branch.rs | `LaneEvent` dedupe/provenance, `LaneBoard` |
+| prompt | prompt.rs | `SystemPromptBuilder`, `ContextFile`, dynamic boundary marker |
+| git/remote/auth | git_context.rs, remote.rs, oauth.rs | Upstream proxy, PKCE flow |
+| misc | json.rs, sse.rs, g004_conformance.rs, green_contract.rs, recovery_recipes.rs, report_schema.rs, trident.rs | Report v1 + redaction |
+
+Largest files by line count: config.rs (3894), mcp_stdio.rs (2969), lane_events.rs (2561), worker_boot.rs (2441), session.rs (1961), conversation.rs (1878).
+
+## CONVENTIONS
+
+- One file per module, flat layout. No subdirectories.
+- Most modules are private `mod x` with selective `pub use`. 21 modules are `pub mod`, so consumers use both the re-export and the qualified path.
+- Deps kept minimal: serde, tokio, glob, regex, sha2, walkdir + internal plugins/telemetry. No reqwest, no async-trait. Remote/SSE done by hand.
+- Inline `#[cfg(test)]` tests per file. session.rs has two test modules.
+- `pub(crate) test_env_lock()` mutex in lib.rs serializes env-mutating tests. Use it when touching env vars.
+- trust_resolver.rs is `#[cfg(test)]`-gated yet pub-used: test-only API surface.
+
+## INVARIANTS (do not break)
+
+1. **Compaction pairs**: compact.rs must never split assistant(ToolUse)/ToolResult pairs.
+2. **No side effects on construction**: SessionStore construction must not create `.claw` directories (session_control.rs:1090).
+3. **Workspace containment**: file_ops.rs workspace ops must not escape the workspace root.
+4. **Permission ordering**: a leading read-only permission token must not launder a trailing destructive one (permission_enforcer.rs:450).
+
+## ANTI-PATTERNS
+
+- Don't extend whole-file `#![allow(...)]` blocks. They exist as legacy tolerance in worker_boot.rs, mcp_tool_bridge.rs, lsp_client.rs, stale_branch.rs, stale_base.rs, recovery_recipes.rs, mcp_lifecycle_hardened.rs, session_control.rs. Adding new ones is not acceptable.
+- Don't add reqwest or async-trait as deps. Remote calls go through the manual SSE/proxy layer in remote.rs and sse.rs.
+- Don't create subdirectories under src/. The flat module layout is intentional.
+- Don't bypass `*_in_workspace` variants for file ops when running inside a workspace context. The unchecked versions exist for bootstrap and out-of-workspace scenarios only.
+- Don't add new `pub mod` exports without reason. Prefer private mod + selective `pub use` from lib.rs.

+/// Candidate `unshare` user-namespace mapping options, in preference order.
+///
+/// Most systems accept `--map-root-user` alone. Some hardened containers and
+/// seccomp profiles block unprivileged writes to `/proc/self/uid_map`; there,
+/// util-linux delegates to the setuid `newuidmap`/`newgidmap` helpers when
+/// `--map-auto` is also present.
+///
+/// That fallback therefore depends on the setuid helpers (the `uidmap`
+/// package on Debian/Ubuntu) and on the current user having a range in
+/// `/etc/subuid` and `/etc/subgid`. When either is missing, `--map-auto`
+/// fails and the startup probe rejects the candidate, keeping the plain form.
+///
+/// Each candidate is the **complete** static argument shape the launcher
+/// uses (see `build_linux_sandbox_command`): mapping flags followed by the
+/// namespace flags `--mount --ipc --pid --uts --fork`. The startup probe
+/// runs each candidate verbatim (plus a trivial program), so probe success
+/// implies launch success: on systems where the mapping works but the
+/// namespace flags are denied (e.g. AppArmor-restricted CI runners that
+/// block mount propagation in user namespaces), the probe fails and the
+/// sandbox stays disabled instead of activating a launcher that always
+/// errors.
+///
+/// `--net` is intentionally absent: it is appended only when network
+/// isolation is active (the non-default path), and probing with it would
+/// disable the sandbox on hosts that block network-namespace creation (e.g.
+/// Docker's default seccomp profile) even when network isolation is never

+# AGENTS.md — rusty-claude-cli (the `claw` binary)
+
+## OVERVIEW
+
+Crate `rusty-claude-cli` produces the `claw` binary (~25 subcommands). Wires together api, runtime, tools, commands, plugins; terminal via crossterm/rustyline/syntect. Hand-rolled arg parser (no clap).
+
+## main.rs MAP
+
+src/main.rs is ~19,800 lines. Landmark table:
+
+| Lines | Section |
+|---|---|
+| 73–330 | Provenance/model types (`ModelSource`, `ModelProvenance`, `PermissionModeSource`), build constants |
+| 330–682 | Error taxonomy (`classify_error_kind`, JSON/text error output) |
+| 774–994 | Global flags, `--cwd`/`-C` stripping, stdin plumbing |
+| 995–1158 | `run()`: single flat match dispatching `CliAction` variants |
+| 1162–1280 | `CliAction` enum, 25 struct variants (each carries `output_format`) |
+| 1312–1477 | Output-format machinery: `OnceLock` statics, duplicate-flag tracking |
+| 1478–2272 | `parse_args`: ~800-line manual token loop |
+| 2542–3389 | Per-subcommand sub-parsers inside `parse_args` |
+| 2902–3389 | Model/permission/allowed-tools resolution |
+| 3390–4696 | Doctor subsystem (~13 `check_*_health` fns) |
+| 4697–6062 | Manifests, bootstrap-plan, system-prompt, version, `resume_session` |
+| 5459–7047 | `StatusContext`, `BinaryProvenance`, broad-cwd policy, stale-base preflight |
+| 7048–9423 | `run_repl` interactive loop (`LiveCli` struct, streaming, heartbeat, `HookAbortMonitor`) |
+| 9424–14264 | Snapshot printers: session-list, status, sandbox, models, help topics, acp, `run_init` (L11027), `run_export` (L11715), `print_help` (L14055) |
+| 14266–19831 | In-file `mod tests` + 3 smaller test modules (one embeds a Python MCP fixture) |
+
+## CONVENTIONS
+
+- Every subcommand supports `--output-format text|json`, env-overridable.
+- `raw_args_request_json_output` pre-scans argv before parsing to suppress stderr config warnings in JSON mode.
+- Dual renderers for each output path: human text + structured `*_json`.
+- Unknown flags/typos get levenshtein-distance suggestions.
+- Comments carry issue numbers (#824, #146, etc.) when tracking known problems.
+- `main()` (L330) is only the error envelope. All real work happens in `run()`.
+- Error output always includes `status`, `error_kind`, `action`, `hint`, `exit_code` fields.
+- `classify_error_kind` maps message prefixes to snake_case kind tokens.
+- JSON errors go to stdout, text errors to stderr.
+- Sibling modules: `init.rs`, `input.rs` (rustyline), `render.rs` (MarkdownStreamState, Spinner, syntect), `setup_wizard.rs`.
+- `build.rs` injects `GIT_SHA`, `RUSTC_VERSION`, `GIT_DIRTY` via `cargo:rustc-env`.
+
+## ANTI-PATTERNS
+
+- File opens with crate-wide `#![allow(...)]` suppressing 13 lints including `dead_code` and `unused_imports`. Legacy. Do NOT extend this list.
+- 9+ functions carry `#[allow(clippy::too_many_lines)]`. Tolerated, not license for more.
+- Package/bin name mismatch: crate is `rusty-claude-cli`, binary is `claw`. Watch for this in paths and test macros.
+
+## TESTS
+
+All tests live in `tests/` (6 files), black-box style. They spawn `env!("CARGO_BIN_EXE_claw")` in unique temp dirs (AtomicU64 counter).
+
+| File | What it covers |
+|---|---|
+| `output_format_contract.rs` | ~105 tests pinning `kind`/`status`/`action` JSON contract for EVERY subcommand. Must update when adding/changing any command output. 5,986 lines. |
+| `resume_slash_commands.rs` | Resume and slash-command behavior |
+| `cli_flags_and_config_defaults.rs` | Flag parsing, config file defaults |
+| `compact_output.rs` | Compact output mode |
+| `compact_repl_panic.rs` | Nested-runtime panic regression |
+| `mock_parity_harness.rs` | Scenario-driven tests against mock-anthropic-service, driven by `rust/mock_parity_scenarios.json` |

+
+## OVERVIEW
+
+Single-crate tool surface: registry, 55 tool specs, permission-gated dispatch, all implementations. One flat `src/lib.rs` (10,892 lines, ~37% tests).
+
+## lib.rs MAP
+
+| Lines | Landmark |
+|-------------|----------|
+| 1–74 | Imports + six `global_*_registry()` OnceLock singletons (Lsp, McpTool, Team, Cron, Task, Worker) |
+| 75–483 | Registry API: `ToolManifestEntry`, `ToolSource`, `ToolRegistry`, `ToolSpec`, `GlobalToolRegistry`, `RuntimeToolDefinition`, `canonical_allowed_tool_name` |
+| 484–1348 | `mvp_tool_specs()` static table of 55 tools with inline JSON schemas |
+| 1349–1524 | `enforce_permission_check` + `execute_tool()` string-match dispatch, permission classification helpers |
+| 1525–2735 | `run_*` wrappers: deserialize input, call into `execute_*` or runtime fns |
+| 2736–2763 | `workspace_traversal_guard_tests` mod |
+| 2764–3354 | ~45 private serde IO structs |
+| 3355–6824 | Real implementations: web fetch/search, todo store, skill resolution, agent/subagent spawning (`ProviderRuntimeClient` L5182, `SubagentToolExecutor` L5361), notebook edit, sleep, config, plan-mode, structured output, REPL, PowerShell |
+| 6825–6826 | `pub mod lane_completion; pub mod pdf_extract;` |
+| 6829–10892 | `mod tests` (~4000 lines) |
+
+## ADDING A TOOL
+
+1. Add a `ToolSpec` entry in `mvp_tool_specs()`. Include `name`, `description`, `input_schema` (inline JSON), and `required_permission: PermissionMode`.
+2. Add a dispatch arm in `execute_tool()` matching the tool name string.
+3. Write a `run_<tool>()` wrapper. Deserialize input from a dedicated serde struct.
+4. Implement the actual logic below L3355 (or call into another crate).
+5. Add inline tests in `mod tests`. Follow BDD naming: `given_x_when_y_then_z`.
+6. Permission gating is automatic: `GlobalToolRegistry` / `SubagentToolExecutor` hold an optional `PermissionEnforcer` checked pre-dispatch.
+
+## CONVENTIONS
+
+- **Tool boundary signature**: `Result<String, String>`. Always.
+- **Tool naming**: snake_case for file/shell tools, PascalCase otherwise. `canonical_allowed_tool_name` normalizes aliases.
+- **State**: OnceLock registries for global singletons. JSON state files under config dirs for persistence.
+- **Input validation**: reject empty strings for todos, descriptions, prompts, messages, code. ~12 validation sites between L3806–6167. Keep that contract.
+- **Test naming**: BDD style (`given_x_when_y_then_z`).
+- **Env-mutating tests**: acquire `env_lock()` mutex first.
+- **Dependencies**: runtime, api, plugins, commands, reqwest(blocking), aspect-*, tokio.
+
+## ANTI-PATTERNS
+
+- **Don't add more `#[allow(clippy::...)]` suppressions.** ~50 `needless_pass_by_value` and several `too_many_lines` allows exist as legacy debt. Don't extend.
+- **Don't skip input validation.** Empty-string rejection is a contract across all user-facing text fields.
+- **Don't scatter implementation across new submodules.** The crate is intentionally flat (one lib.rs + two leaf mods). Only `lane_completion` and `pdf_extract` break out.
+- **Don't duplicate tool names.** The canonical name mapping already handles aliases.
+- **Don't bypass `enforce_permission_check`.** Every tool dispatch goes through permission gating. No exceptions.

+built with, or shipped in the Rust product (`rust/crates/`). The Python tree exists
+solely to mirror and track parity against the Claude Code TypeScript source.
+
+## STRUCTURE
+
+```
+src/
+├── main.py              # argparse CLI entry point (summary, parity-audit, manifest, etc.)
+├── ~38 top-level .py    # mirror TS root files one-to-one
+├── models.py            # frozen dataclasses: Subsystem, PortingModule, PermissionDenial, ...
+├── parity_audit.py      # hard-coded TS→Python filename mapping (main.tsx→main.py, etc.)
+├── port_manifest.py     # builds a manifest of the src/ tree itself
+├── reference_data/      # tracked JSON snapshots extracted from the TS archive
+│   ├── archive_surface_snapshot.json
+│   ├── tools_snapshot.json, commands_snapshot.json
+│   └── subsystems/*.json   (29 per-subsystem records)
+└── ~30 subdirectories/  # PLACEHOLDER PACKAGES (assistant/, bootstrap/, voice/, vim/, ...)
+    └── each contains only __init__.py loading subsystems/<name>.json
+```
+
+Placeholder packages follow an identical template: load
+`reference_data/subsystems/<name>.json` via `_archive_helper.load_archive_metadata()`,
+re-export `ARCHIVE_NAME`, `MODULE_COUNT`, `SAMPLE_FILES`, `PORTING_NOTE`. There is no
+voice, vim, or other real functionality behind them.
+
+## WHERE TO LOOK
+
+| Goal | Start here |
+|---|---|
+| Understand the CLI subcommands | `main.py` |
+| See which TS files map to which .py | `parity_audit.py` |
+| Find shared data structures | `models.py` |
+| Check TS archive metadata | `reference_data/` |
+| Real logic (permissions, path scoping) | `permissions.py`, `path_scope.py` |
+| Query engine shim | `query_engine.py` |
+| Runtime simulation | `runtime.py` |
+| Tests | repo-root `tests/` (test_porting_workspace.py, test_security_scope.py) |
+
+Run tests: `python -m unittest discover -s tests` from repo root.
+
+## CONVENTIONS
+
+- snake_case filenames, preserving TS names. camelCase exceptions exist where the
+  TS original used it: `QueryEngine.py`, `costHook.py`, `replLauncher.py`.
+- Every mirrored entry carries a `source_hint` pointing back to its original `.ts`/`.tsx` path.
+- `from __future__ import annotations` throughout. Stdlib only, no third-party deps.
+- `models.py` dataclasses are frozen. Renderers are `as_markdown()` / `to_markdown()`.
+- main.py simulates routing, turn-loops, bootstrap over mirrored inventories.
+  Read-only shims return handled/message results. It never calls an LLM.
+- Thin shim modules (e.g. `ink.py`) exist as backlog metadata, not working code.
+
+## ANTI-PATTERNS
+
+**Don't add real agent, tool, voice, or vim functionality here.** That belongs in
+`rust/crates/`. This tree is a scaffold, not an implementation target.
+
+**Don't commit anything from `archive/`.** The local TS snapshot
+(`archive/claude_code_ts_snapshot/src`) is gitignored. `reference_data/` holds the
+tracked extracts; work from those.
+
+**Don't let parity_audit.py drift.** When you rename a mirrored module, update the
+hard-coded mapping in `parity_audit.py` to match.
+
+**Don't add third-party dependencies.** Everything runs on stdlib.
