+## 7. Project Architecture
+
+Huskies is a single Rust binary with an embedded React frontend. Key things to know:
+
+- **Backend:** `server/src/` — Rust, built with Poem (HTTP framework)
+- **Frontend:** `frontend/src/` — React + TypeScript, built with Vite
+- **Gateway mode:** `huskies --gateway` is a deployment mode of the same binary, NOT a separate application. The gateway backend code lives in `server/src/gateway.rs`. Gateway frontend components live in `frontend/src/` alongside everything else.
+- **Stories that say "UI":** These are primarily frontend (TypeScript/React) work. Check what backend endpoints already exist before adding new ones. Keep Rust changes minimal.
+- **Stories that say "gateway":** The gateway is just a mode. Don't restructure `gateway.rs` unless the story specifically asks for backend changes.
+
+---
+
+## 8. Deployment Modes
+
+Huskies has three modes, all from the same binary:
+
+### Standard (single project)
+
+```
+huskies [--port 3001] /path/to/project
+```
+
+Full server: web UI, MCP endpoint, chat bot, agent pool, pipeline. One project per instance.
+
+### Headless Build Agent
+
+```
+huskies --rendezvous ws://host:port/crdt-sync
+```
+
+Connects to an existing huskies instance as a worker node. Syncs the CRDT, claims work from the pipeline, runs agents. No web UI, no chat — just a build worker. Use this to add more compute to a project by running extra containers.
+
+### Gateway (multi-project)
+
+```
+huskies --gateway [--port 3000] /path/to/config
+```
+
+Lightweight proxy that sits in front of multiple project containers. Reads a `projects.toml` that maps project names to container URLs:
+
+```toml
+[projects.huskies]
+url = "http://huskies:3001"
+
+[projects.robot-studio]
+url = "http://robot-studio:3002"
+```
+
+The gateway presents a unified MCP surface to the chat agent. All tool calls are proxied to the active project's container. Gateway-specific tools:
+
+| Tool | Purpose |
+|------|---------|
+| `switch_project` | Change the active project |
+| `gateway_status` | Show active project and list all registered projects |
+| `gateway_health` | Health check all containers |
+
+### Example: multi-project Docker Compose
+
+```yaml
+services:
+  gateway:
+    image: huskies
+    command: ["huskies", "--gateway", "--port", "3000", "/workspace"]
+    ports:
+      - "127.0.0.1:3000:3000"
+    depends_on: [huskies, robot-studio]
+
+  huskies:
+    image: huskies
+    volumes:
+      - /path/to/huskies:/workspace
+
+  robot-studio:
+    image: huskies
+    environment:
+      - HUSKIES_PORT=3002
+    volumes:
+      - /path/to/robot-studio:/workspace

-3. If merge succeeded and gates passed: report success to the human
-4. If conflicts were auto-resolved (conflicts_resolved=true) and gates passed: report success, noting which conflicts were resolved
-5. If conflicts could not be auto-resolved: **resolve them yourself** in the merge worktree (see below)
-6. If merge failed for any other reason: call report_merge_failure(story_id='{{story_id}}', reason='<details>') and report to the human
-7. If gates failed after merge: attempt to fix the issues yourself in the merge worktree, then re-trigger merge_agent_work. After 3 fix attempts, call report_merge_failure and stop.
-
-## Resolving Complex Conflicts Yourself
-
-When the auto-resolver fails, you have access to the merge worktree at `.story_kit/merge_workspace/`. Go in there and resolve the conflicts manually:
-
-1. Run `git diff --name-only --diff-filter=U` in the merge worktree to list conflicted files
-2. **Build context before touching code.** Run `git log --oneline master...HEAD` on the feature branch to see its commits. Then run `git log --oneline --since="$(git log -1 --format=%ci <feature-branch-base-commit>)" master` to see what landed on master since the branch was created. Read the story files in `.story_kit/work/` for any recently merged stories that touch the same files — this tells you WHY master changed and what must be preserved.
-3. Read each conflicted file and understand both sides of the conflict
-4. **Understand intent, not just syntax.** The feature branch may be behind master — master's version of shared infrastructure is almost always correct. The feature branch's contribution is the NEW functionality it adds. Your job is to integrate the new into master's structure, not pick one side.
-5. Resolve by integrating the feature's new functionality into master's code structure
-5. Stage resolved files with `git add`
-6. Call the `run_tests` MCP tool to start tests, then poll `get_test_result` until complete
-7. If it compiles, commit and re-trigger merge_agent_work
-
-### Common conflict patterns in this project:
-
-**Story file rename/rename conflicts:** Both branches moved the story .md file to different pipeline directories. Resolution: `git rm` both sides — story files in `work/2_current/`, `work/3_qa/`, `work/4_merge/` are gitignored and don't need to be committed.
-
-**bot.rs tokio::select! conflicts:** Master has a `tokio::select!` loop in `handle_message()` that handles permission forwarding (story 275). Feature branches created before story 275 have a simpler direct `provider.chat_stream().await` call. Resolution: KEEP master's tokio::select! loop. Integrate only the feature's new logic (e.g. typing indicators, new callbacks) into the existing loop structure. Do NOT replace the loop with the old direct call.
-
-**Duplicate functions/imports:** The auto-resolver keeps both sides, producing duplicates. Resolution: keep one copy (prefer master's version), delete the duplicate.
-
-**Formatting-only conflicts:** Both sides reformatted the same code differently. Resolution: pick either side (prefer master).
+1. Call merge_agent_work(story_id='{{story_id}}'). It blocks until the merge completes and returns the full result.
+2. If success and gates passed: you're done. Exit.
+3. If gates failed: read the gate_output carefully, fix the issues in the merge workspace at `.huskies/merge_workspace/`, run run_tests MCP tool to verify, recommit, and call merge_agent_work again.
+4. If merge failed for any other reason: call report_merge_failure(story_id='{{story_id}}', reason='<details>') and exit.
+5. After 3 failed fix attempts, call report_merge_failure and exit.
 
 ## Fixing Gate Failures
 
-If quality gates fail, attempt to fix issues yourself in the merge worktree. Use the run_tests MCP tool (then poll get_test_result) to verify — do not run script/test via Bash.
+The auto-resolver often produces broken code. Common problems:
+- Duplicate imports or definitions (kept both sides)
+- Formatting issues (import ordering, line breaks)
+- Unclosed delimiters from bad conflict resolution
+- Type mismatches from incompatible merge of both sides
 
-**Fix yourself (up to 3 attempts total):**
-- Syntax errors (missing semicolons, brackets, commas)
-- Duplicate definitions from merge artifacts
-- Simple type annotation errors
-- Unused import warnings flagged by clippy
-- Mismatched braces from bad conflict resolution
-- Trivial formatting issues that block compilation or linting
+To fix:
+1. Read the broken files in `.huskies/merge_workspace/`
+2. Fix the issues — prefer master's structure, integrate only the feature's new code
+3. Run run_lint MCP tool to check formatting
+4. Run run_tests MCP tool to verify everything passes
+5. Commit the fix and call merge_agent_work again
 
-**Report to human without attempting a fix:**
-- Logic errors or incorrect business logic
-- Missing function implementations
-- Architectural changes required
-- Non-trivial refactoring needed
-
-**Max retry limit:** If gates still fail after 3 fix attempts, call report_merge_failure to record the failure, then stop immediately and report the full gate output to the human.
-
-## CRITICAL Rules
-- NEVER manually move story files between pipeline stages (e.g. from 4_merge/ to 5_done/)
-- NEVER call accept_story — only merge_agent_work can move stories to done after a successful merge
-- When merge fails after exhausting your fix attempts, ALWAYS call report_merge_failure
-- Report conflict resolution outcomes clearly
-- Report gate failures with full output so the human can act if needed
-- The server automatically runs acceptance gates when your process exits"""
-system_prompt = "You are the mergemaster agent. Your primary job is to merge feature branches to master. First try the merge_agent_work MCP tool. If the auto-resolver fails on complex conflicts, resolve them yourself in the merge worktree — you are an opus-class agent capable of understanding both sides of a conflict and producing correct merged code. Common patterns: keep master's tokio::select! permission loop in bot.rs, discard story file rename conflicts (gitignored), remove duplicate definitions. After resolving, verify compilation before re-triggering merge. CRITICAL: Never manually move story files or call accept_story. After 3 failed fix attempts, call report_merge_failure and stop."

-# Tech Stack & Constraints
+# Tech Stack
 
-## Overview
-This project is a standalone Rust **web server binary** that serves a Vite/React frontend and exposes a **WebSocket API**. The built frontend assets are packaged with the binary (in a `frontend` directory) and served as static files. It functions as an **Agentic Code Assistant** capable of safely executing tools on the host system.
+## Backend
+- **Language:** Rust
+- **Framework:** Poem (HTTP + WebSocket + OpenAPI)
+- **Database:** SQLite via sqlx + rusqlite
+- **State:** BFT CRDT replicated document backed by SQLite
+- **Agents:** Claude Code CLI spawned in PTY pseudo-terminals
+- **Package manager:** cargo
 
-## Core Stack
-*   **Backend:** Rust (Web Server)
-    *   **MSRV:** Stable (latest)
-    *   **Framework:** Poem HTTP server with WebSocket support for streaming; HTTP APIs should use Poem OpenAPI (Swagger) for non-streaming endpoints.
-*   **Frontend:** TypeScript + React
-    *   **Build Tool:** Vite
-    *   **Package Manager:** npm
-    *   **Styling:** CSS Modules or Tailwind (TBD - Defaulting to CSS Modules)
-    *   **State Management:** React Context / Hooks
-    *   **Chat UI:** Rendered Markdown with syntax highlighting.
+## Frontend
+- **Language:** TypeScript + React
+- **Build:** Vite
+- **Package manager:** npm
+- **Testing:** Vitest (unit), Playwright (e2e)
 
-## Agent Architecture
-The application follows a **Tool-Use (Function Calling)** architecture:
-1.  **Frontend:** Collects user input and sends it to the LLM.
-2.  **LLM:** Decides to generate text OR request a **Tool Call** (e.g., `execute_shell`, `read_file`).
-3.  **Web Server Backend (The "Hand"):**
-    *   Intercepts Tool Calls.
-    *   Validates the request against the **Safety Policy**.
-    *   Executes the native code (File I/O, Shell Process, Search).
-    *   Returns the output (stdout/stderr/file content) to the LLM.
-    *   **Streaming:** The backend sends real-time updates over WebSocket to keep the UI responsive during long-running Agent tasks.
+## Deployment
+- Single Rust binary with embedded React frontend (rust-embed)
+- Three modes: standard server, headless build agent (`--rendezvous`), multi-project gateway (`--gateway`)
+- Docker container with OrbStack recommended on macOS
 
-## LLM Provider Abstraction
-To support both Remote and Local models, the system implements a `ModelProvider` abstraction layer.
+## Project Layout
+```
+server/src/          — Rust backend
+frontend/src/        — React frontend
+crates/bft-json-crdt/ — CRDT library
+.huskies/            — Pipeline config, agent config, specs
+script/              — test, build, lint scripts
+docker/              — Dockerfile and docker-compose
+website/             — Static marketing/docs site
+```
 
-*   **Strategy:**
-    *   Abstract the differences between API formats (OpenAI-compatible vs Anthropic vs Gemini).
-    *   Normalize "Tool Use" definitions, as each provider handles function calling schemas differently.
-*   **Supported Providers:**
-    *   **Ollama:** Local inference (e.g., Llama 3, DeepSeek Coder) for privacy and offline usage.
-    *   **Anthropic:** Claude 3.5 models (Sonnet, Haiku) via API for coding tasks (Story 12).
-*   **Provider Selection:**
-    *   Automatic detection based on model name prefix:
-        *   `claude-` → Anthropic API
-        *   Otherwise → Ollama
-    *   Single unified model dropdown with section headers ("Anthropic", "Ollama")
-*   **API Key Management:**
-    *   Anthropic API key stored server-side and persisted securely
-    *   On first use of Claude model, user prompted to enter API key
-    *   Key persists across sessions (no re-entry needed)

-## Running the App (Worktrees & Ports)
+### HTTP — MCP Tools (the tools agents call)

-- **Backend:** Set `HUSKIES_PORT` to a unique port (default is 3001). Example: `HUSKIES_PORT=3002 cargo run`
-- **Frontend:** Run `npm run dev` from `frontend/`. It auto-selects the next unused port. It reads `HUSKIES_PORT` to know which backend to talk to, so export it before running: `export HUSKIES_PORT=3002 && cd frontend && npm run dev`
+### Chat — Bot Commands
 
-When running in a worktree, use a port that won't conflict with the main instance (3001). Ports 3002+ are good choices.

+| `server/src/chat/commands/run_tests.rs` | `run_tests` command — run the project's test suite |
 
-## Safety & Sandbox
-1.  **Project Scope:** The application must strictly enforce that it does not read/write outside the `project_root` selected by the user.
-2.  **Human in the Loop:**

-# Bug 510: Stale 1_backlog filesystem shadows get re-promoted by rate-limit retry timers, yanking successfully-merged stories back into current
-
-## Description
-
-After a story successfully completes the entire pipeline — coder runs, gates pass, mergemaster squashes the feature branch to master, lifecycle moves the story from `4_merge/` to `5_done/` — a stale filesystem shadow of the story's markdown file remains in `.huskies/work/1_backlog/`. This shadow is a leftover from the 491/492 migration: story state moved to the database as the source of truth, but the lifecycle move logic in `lifecycle.rs` is still operating on the filesystem and doesn't fully clean up after successful pipeline completions.
-
-When a rate-limit retry timer subsequently fires for that story (rate limits get scheduled by story 496's auto-retry whenever an agent is hard-blocked, and bug 501 means those timers aren't cancelled on successful completion either), the timer fire path calls `move_story_to_current()`, which uses the **filesystem-only** `move_item` helper. That helper finds the stale `1_backlog/` shadow and "moves" it to `2_current/` — even though the story is correctly in `5_done` in the database.
-
-Net effect: a fully-merged, archived-to-done story suddenly reappears in `current` with a fresh coder spawned on it. The matrix bot sends `Done → Current` notifications. The agent burns tokens working on a story whose work has already shipped to master. The user sees the story flapping and assumes the merge didn't actually happen.
-
-**Observed live on 2026-04-09 against story 503:**
-
-```
-18:31:32 [lifecycle] Moved '503_…' from work/4_merge/ to work/5_done/
-18:31:32 [bot] Sending stage notification: 🎉 #503 … — Merge → Done
-18:32:21 [timer] Timer fired for story 503_…
-18:32:21 [lifecycle] Moved '503_…' from work/1_backlog/ to work/2_current/   ← stale shadow!
-18:32:21 [auto-assign] Assigning 'coder-1' to '503_…' in 2_current/
-```
-
-The merge to master persisted (commit `41515e3b` is on master). Only the *pipeline state* got corrupted by the stale shadow being re-promoted.
-
-This is **distinct from bug 501** (which is about manual `stop_agent` not cancelling timers) but compounds it: 501 is about user-initiated stops, this is about successful pipeline completions. Both share a root cause — the rate-limit retry timer system has no notion of "this story has moved on, cancel any pending retries" — but the *consequences* of this bug are worse because the timer fires successfully and re-creates work that shouldn't exist.
-
-Also distinct from bug 502 (mergemaster stage-mismatch) which has been fixed.
-
-The deeper architectural problem this exposes: **`lifecycle.rs::move_item` and `move_story_to_current` are still on the legacy filesystem path** while the rest of the pipeline (491/492) has moved to DB-as-source-of-truth. The filesystem shadows in `.huskies/work/N_stage/` are supposed to be a *materialized rendering* of the DB state, not a parallel source of truth — but `move_item` treats them as authoritative.
-
-## How to Reproduce
-
-1. Take any story through the full pipeline successfully — coder runs, gates pass, mergemaster squashes to master, story moves to `5_done`.
-2. While the story was in flight, ensure at least one coder run hit a hard rate limit (so a retry timer was scheduled). Bug 501 means that timer survives the successful completion.
-3. Verify post-completion state:
-   - `SELECT stage FROM pipeline_items WHERE id = 'N_story_X';` returns `5_done` ✓
-   - `ls .huskies/work/1_backlog/N_story_X.md` shows the file STILL EXISTS (the stale shadow)
-   - `cat .huskies/timers.json` shows a pending entry for `N_story_X` with a future `scheduled_at`
-4. Wait for the timer to fire (default ~5 minutes after the last rate-limit hit).
-
-## Actual Result
-
-When the timer fires:
-- The `[timer] Timer fired` log line appears for the already-done story
-- `move_story_to_current` is called and finds the stale `1_backlog/N_story_X.md` shadow
-- Lifecycle log: `[lifecycle] Moved 'N_…' from work/1_backlog/ to work/2_current/`
-- Auto-assign sees the story in `2_current/` and spawns a coder
-- Matrix bot sends `Done → Current` (and then later `Current → Current` etc.) stage notifications, spamming the room
-- The new coder works on a story whose work is already shipped on master, burning tokens
-- The story is now visible in BOTH `5_done` (via DB) AND `2_current` (via filesystem shadow), depending on which view the consumer reads
-- The actual master commit is unaffected — the merge that already landed is still there. Only the *pipeline state* is corrupted.
-
-## Expected Result
-
-Successful pipeline completions must fully clean up the story's filesystem shadows. After `move_story_to_done` runs, `.huskies/work/1_backlog/N_story_X.md` (and any other stage shadow) for that story must not exist.
-
-Additionally — and this is the more general fix — the rate-limit retry timer system must cancel any pending timers for a story when that story successfully completes the pipeline. This is a sibling fix to bug 501 (which is about cancelling on manual stop): both manual stop and successful completion should mean "no more retries".
-
-The deepest fix is to migrate `lifecycle.rs::move_item` off the filesystem path and onto the DB path so the shadow files can be torn down entirely (or made strictly read-only renderings). That's a larger change that probably wants its own story, not a bug fix.
-
-## Acceptance Criteria
-
-- [ ] After a story moves to 5_done via the normal pipeline path (mergemaster success), the filesystem shadow at .huskies/work/1_backlog/N_story_X.md is removed (and any other stage shadows are also removed)
-- [ ] When a story moves to 5_done, any pending rate-limit retry timer for that story is cancelled (the entry is removed from timers.json before the file is persisted)
-- [ ] Regression test: simulate the full repro sequence — run a story through the pipeline with a mid-flight rate limit, complete the merge, fast-forward to the timer fire, assert (a) the story stays in 5_done, (b) no agent is spawned, (c) no Done→Current notification fires
-- [ ] No regression in bug 501's fix for manual-stop timer cancellation
-- [ ] Filesystem shadow cleanup is symmetric — also runs on delete_story, move_story to backlog, etc., not just the done path
-- [ ] The matrix bot does not spam Done→Current notifications for stories whose work has actually completed

-//! Pipeline state machine — design sketch (story 520) — BARE version.
-//!
-//! This is a SCRATCH EXPERIMENT, not wired into anything else in the codebase.
-//! "Bare" version: hand-rolled with plain Rust enums and pattern matching,
-//! no external state-machine library. See `pipeline_state_sketch_statig.rs`
-//! for a parallel version using the `statig` crate.
-//!
-//! Run with:
-//!     cargo run  --example pipeline_state_sketch_bare -p huskies
-//! Test with:
-//!     cargo test --example pipeline_state_sketch_bare -p huskies
-//!
-//! Goal: demonstrate the typed pipeline state machine that should replace
-//! huskies's stringly-typed CRDT state. It is intentionally standalone —
-//! no integration with crdt_state, no persistence, no events escape this
-//! file. Once we agree on the shape, this becomes the foundation for the
-//! real implementation in src/pipeline_state.rs.
-//!
-//! The point of this version is to show that the Rust type system alone is
-//! enough to make impossible states unrepresentable, without needing any
-//! state-machine framework.

-//! Pipeline state machine — design sketch (story 520) — STATIG version.
-//!
-//! Parallel to `pipeline_state_sketch_bare.rs`. Same domain types, same
-//! transitions, same event semantics — but the state machine is built using
-//! the `statig` crate (https://crates.io/crates/statig) instead of being
-//! hand-rolled.
-//!
-//! Run with:
-//!     cargo run  --example pipeline_state_sketch_statig -p huskies
-//! Test with:
-//!     cargo test --example pipeline_state_sketch_statig -p huskies
-//!
-//! Why both versions?
-//!
-//! - The **bare** version shows that plain Rust enums + a transition function
-//!   are *enough* to make impossible states unrepresentable. No framework.
-//! - The **statig** version shows what we'd gain by adopting a state-machine
-//!   crate: hierarchical states (the `active` superstate factors out the
-//!   cross-cutting Block/ReviewHold/Abandon/Supersede transitions, which the
-//!   bare version had to duplicate inline with `|` patterns), generated
-//!   `State` enum with type-safe data-carrying constructors, and stateful
-//!   `handle(&event)` dispatch. Type safety is preserved either way:
-//!   `State::merge(BranchName, NonZeroU32)` requires both args at the
-//!   constructor, just like `Stage::Merge { feature_branch, commits_ahead }`
-//!   in the bare version.
-//!
-//! Trade-off: statig adds a dependency and a proc-macro layer, which makes
-//! the code harder to read for someone unfamiliar with the crate. The
-//! framework-free version is more transparent but requires manual
-//! pattern-matching and inline duplication for cross-cutting transitions.

-// ── Side effects via statig's entry/exit actions (alternative to EventBus) ───
-//
-// The bare version uses an explicit EventBus + Subscriber trait + per-state
-// publish-on-transition pattern. statig has a more native equivalent:
-// `#[action]`-tagged functions that fire on state entry / exit / transition.
-//
-// We don't include a full action-based example here — it would roughly look
-// like adding `entry_action = "log_entry"` to each #[state] attribute and
-// defining `fn log_entry(...)` in the impl block. The trade-off is that
-// statig's actions are tightly coupled to the state machine impl block,
-// while the bare version's EventBus allows arbitrary external subscribers
-// to plug in without touching the state machine code. Both patterns are
-// valid; pick based on whether you want side-effect dispatch INSIDE the
-// machine (statig actions) or OUTSIDE it (bare EventBus).
