fix: add missing thought_signature field in tools tests

Fixes two test assertions that were missing the new Option<String> field added to the pending_tools tuple. Generated with https://github.com/Yeachan-Heo/gajae-code Co-authored-by: Gajae Code <dev@gajae-code.com>
In the provider compatibility layer for Gemini (and other providers requiring ), fully support the flow, round-trip, and placeholder fallback of thought_signature.

-## 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.

-(Refs = rg count across rust/crates; rust-analyzer references timed out during mapping.)
-
-## 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

-> [!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.
->
-> For the longer public explanation behind this philosophy, see [here](https://x.com/realsigridjin/status/2039472968624185713).

-> [!IMPORTANT]
-> **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。

-> [!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
-```

-Legacy bare-string hook entries still load for backward compatibility but emit deprecation warnings suggesting migration to object-style entries. Unknown hook event names (e.g. `Stop`, `Notification`) are recorded as invalid without rejecting valid hooks. `status --output-format json` mirrors partial hook validation under `hook_validation` with `valid_count`, `invalid_count`, and `invalid_hooks:[{event, index, hook_index, kind, error_field, reason, valid:false}]`. `doctor --output-format json` includes a `hook validation` check so automation can repair every rejected hook entry without losing usable hooks.

@@ -25,8 +25,7 @@ Routing notes:

 - Use the `openai/` prefix for OpenAI-compatible gateways when you need prefix routing to win over ambient Anthropic credentials, for example `--model "openai/gpt-4.1-mini"` with OpenRouter.
 - For local servers, prefer the exact model ID reported by the server (`qwen3:latest`, `llama3.2`, etc.). If your local gateway exposes slash-containing IDs, prefix the exact slug with `local/` so Claw routes through OpenAI-compatible transport while sending the rest verbatim, for example `--model "local/Qwen/Qwen2.5-Coder-7B-Instruct"`.
- When `OPENAI_BASE_URL` points at a loopback or private-network address (`localhost`, `127.0.0.1`, `10.x`, `192.168.x`, `172.16-31.x`), Claw accepts **any** non-empty model name — bare aliases like `mistral` work with no dot, colon, or slash required. 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.
+- If you have multiple provider keys in your environment, `OPENAI_BASE_URL` plus local-looking tags such as `llama3.2` or `qwen2.5-coder:7b` selects the local OpenAI-compatible route; use `local/` for slash-containing local IDs.
 - Tool workflows need model/server support for OpenAI-compatible tool calls. Plain prompt smoke tests can pass even when slash/tool workflows still fail because the server returns an incompatible tool-call shape.

-# 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.

-# AGENTS.md — rust/ workspace
-
-## OVERVIEW
-
-Virtual Cargo workspace (resolver 2, edition 2021) housing 11 crates that compose the `claw` CLI and supporting services.
-
-## STRUCTURE
-
-| Crate | Kind | Purpose |
-|---|---|---|
-| `rusty-claude-cli` | bin (`claw`) | Main CLI binary. Package name ≠ binary name. |
-| `claw-analog` | lib+bin | Alternate entry point; depends on api + runtime only. |
-| `claw-rag-service` | bin | RAG service. Only crate with `[features]` (`qdrant-index`). |
-| `mock-anthropic-service` | lib+bin | Mock Anthropic Messages API. Prints `MOCK_ANTHROPIC_BASE_URL`. Dev-dep for CLI and analog tests. |
-| `runtime` | lib | Core: sessions, permissions, MCP, conversation loop. ~47 modules. |
-| `api` | lib | Provider clients: Anthropic, OpenAI-compat (xAI, OpenAI, DashScope, Ollama). |
-| `tools` | lib | 55-tool surface area. Depends on `commands` (not vice versa). |
-| `commands` | lib | 120+ slash commands. |
-| `plugins` | lib | Plugin manifest and lifecycle. |
-| `telemetry` | lib | Request identity + analytics sinks. |
-| `compat-harness` | lib | Extracts upstream TS claude-code manifest/commands/tools for parity comparison. |
-
-Dependency direction: `rusty-claude-cli` → tools/commands/runtime/api/plugins. `tools` → `commands`.
-
-## WHERE TO LOOK
-
- **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)

-
-# 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 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`.
+Short names resolve to the latest model versions:

-| Alias | Resolves To | Provider | Auth env var |
-|-------|-------------|----------|--------------|
-| `opus` | `claude-opus-4-7` | Anthropic | `ANTHROPIC_API_KEY` |
-| `sonnet` | `claude-sonnet-4-6` | Anthropic | `ANTHROPIC_API_KEY` |
-| `haiku` | `claude-haiku-4-5-20251213` | Anthropic | `ANTHROPIC_API_KEY` |
-| `grok`, `grok-3` | `grok-3` | xAI | `XAI_API_KEY` |
-| `grok-mini`, `grok-3-mini` | `grok-3-mini` | xAI | `XAI_API_KEY` |
-| `grok-2` | `grok-2` | xAI | `XAI_API_KEY` |
-| `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
-provider-specific request handling see
-[`../docs/MODEL_COMPATIBILITY.md`](../docs/MODEL_COMPATIBILITY.md).

 ## CLI Flags and Commands

@@ -173,7 +151,6 @@ Top-level commands:
 `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.

-# AGENTS.md — plugins crate
-
-## 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.

-/// Hardening notes:
-/// - Any shell metacharacter that could chain, substitute, pipe, or redirect
-///   into a state-changing command rejects the whole line. This blocks
-///   `cat x; rm -rf y`, `cat x | sh`, `$(...)`, backticks, redirects, and
-///   subshells regardless of the leading token.
-/// - Language interpreters (`python`, `node`, `ruby`) and build drivers
-///   (`cargo`, `rustc`) are NOT read-only: they execute arbitrary code, so they
-///   are excluded from the allow-list.
-/// - `git` is allowed only for a known set of non-mutating subcommands.
-/// - `find` is rejected when it carries an action that can execute or delete.
-///
-/// Residual known gaps (documented, not yet closed): `sed`'s `w`/`e` script
-/// commands and `awk`'s `system()` can still mutate — these require quoting or
-/// metacharacters that the checks above usually catch, but a dedicated parser
-/// would be more robust. Tracked as follow-up.

-/// 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
-

-## 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.

-# src/ AGENTS.md
-
-## OVERVIEW
-
-This is a **porting workspace**, not production code. Nothing here is imported by,
-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.
