## Checklist

### Completeness
- [x] FR-1 CI fix: `colonyos[ui]` added to dev extras in pyproject.toml
- [x] FR-2 Server tests can run in CI (fastapi/starlette now in dev deps)
- [x] FR-3 `web-build` CI job added with npm ci, test, and build steps
- [x] FR-4 PUT /api/config implemented with validation
- [x] FR-5 PUT /api/config/personas implemented with per-persona validation
- [x] FR-6 POST /api/runs implemented with background thread
- [x] FR-7 GET /api/artifacts/{path} with path traversal protection
- [x] FR-8 Bearer token auth with secrets.token_urlsafe(32) and constant-time comparison
- [x] FR-9 COLONYOS_WRITE_ENABLED flag gates all write endpoints
- [x] FR-10 Sensitive field mutations blocked (_SENSITIVE_CONFIG_FIELDS)
- [x] FR-11 Rate limit via threading.Semaphore(1)
- [x] FR-12 Config page inline-editable
- [x] FR-13 PersonaCard editable with add/remove
- [x] FR-14 RunLauncher with confirmation dialog
- [x] FR-15 ArtifactPreview with markdown rendering

- [x] FR-20 Component tests for PersonaCard, PhaseTimeline, RunList, StatsPanel, Layout
- [x] FR-21 Page tests for Dashboard, RunDetail, Config
- [x] FR-22 API client tests

### Quality
- [x] No TODO/FIXME/HACK markers in shipped code
- [x] Code follows existing project conventions (dataclass serialization, sanitization patterns)
- [x] No unnecessary dependencies (only vitest/RTL for testing, fastapi/uvicorn in ui extra)
- [x] Tests cover auth, validation, path traversal, rate limiting, semaphore safety

### Safety
- [x] No secrets in committed code
- [x] Bearer token generated per-session, compared with secrets.compare_digest
- [x] Path traversal defense: allowlist + resolve + is_relative_to
- [x] Artifact content sanitized via sanitize_untrusted_content
- [x] ArtifactPreview has HTML entity escaping + allowlisted tag sanitization + dangerouslySetInnerHTML

## Findings

- [src/colonyos/server.py:303-340] POST /api/runs returns `{"status": "launched"}` without a `run_id`. The PRD (FR-6) says "return the new run_id immediately." The docstring acknowledges this deviation (run_id assigned async by orchestrator), but the task file (3.5) also says `return {"run_id": str}`. This is a pragmatic trade-off — the orchestrator creates the run_id inside the thread — but it's a spec deviation. The client navigates to "/" and relies on polling, which works but is less satisfying than redirecting to the new run.

- [src/colonyos/server.py:206-237] PUT /api/config manually maps each field one by one (model, budget, phases, project, max_fix_iterations, auto_approve, phase_models). This is tedious but correct — it avoids mass-assignment vulnerabilities. The downside is that adding a new config field requires touching this endpoint. A schema-driven approach would be better long-term, but for now this is the safe and obvious thing to do.

- [src/colonyos/server.py:325-340] The semaphore rate-limiting pattern is correct: acquire non-blocking, release in finally block of the thread, and release in except if Thread creation itself fails. The test at test_server_write.py:366-387 verifies semaphore recovery. Good.

- [src/colonyos/server.py:297-301] GET /api/auth/verify uses `_require_write_auth()` which checks both COLONYOS_WRITE_ENABLED and the bearer token. This is a GET endpoint that performs auth. Unconventional but functional — the frontend needs it to verify the token before storing it.

- [web/src/components/ArtifactPreview.tsx:39-125] Hand-rolled markdown renderer. It escapes HTML entities first, then applies regex-based formatting. The sanitizeHtml allowlist is a second layer. This is adequate for a localhost tool. In a different context I'd demand a real parser, but the entity-escape-first approach means the "markdown" patterns only match on already-escaped content, which prevents XSS injection through the rendering pipeline.

- [tests/conftest.py] New conftest.py creates a tmp_repo fixture with .colonyos/runs/ directory. This is new (doesn't exist on main). The `pythonpath` in pyproject.toml was updated to include `tests/` to support `from conftest import write_config`. This is fine but slightly unusual — pytest normally auto-discovers conftest.py.

- [web/src/components/AuthTokenPrompt.tsx:13-17] On network error during token verification, the code returns `true` (assumes valid). The comment says "to avoid blocking the user." This is the right tradeoff for a localhost tool — if the server is down, the token prompt shouldn't be a brick wall.

- [pyproject.toml] The circular-ish dependency `dev = [..., "colonyos[ui]"]` is unusual but works with pip. It means `pip install -e ".[dev]"` will also install the `ui` extras. This is the simplest fix for the CI problem.

## Verdict

VERDICT: approve

FINDINGS:
- [src/colonyos/server.py:303-340]: POST /api/runs returns {"status": "launched"} without run_id, deviating from PRD FR-6. Acceptable pragmatic trade-off since run_id is assigned async by the orchestrator.
- [src/colonyos/server.py:206-237]: Manual field-by-field config update mapping is tedious but correct — prevents mass-assignment. Acceptable for current scope.
- [web/src/components/ArtifactPreview.tsx:39-125]: Hand-rolled markdown renderer with entity-escape-first pattern. Adequate for localhost tool; not what I'd ship for a public-facing service.
- [tests/conftest.py]: pythonpath includes tests/ for conftest imports — slightly unusual but functional.

SYNTHESIS:
This is a solid, well-structured implementation that does the simple and obvious thing at every decision point. The CI fix is a one-liner (adding colonyos[ui] to dev extras) — exactly what it should be. The server code is straightforward FastAPI with no clever abstractions: each endpoint is a flat function that validates input, calls the data layer, and returns JSON. The auth is simple bearer token with constant-time comparison. The write endpoints have explicit field-by-field mapping that prevents mass-assignment. The semaphore-based rate limiting handles failure modes correctly. The frontend is clean React with proper error handling, polling with cleanup, and a layered XSS defense (server-side sanitization + client-side entity escaping + allowlisted tag filter). The only meaningful spec deviation is POST /api/runs not returning a run_id, which is an inherent limitation of the async orchestrator design and is handled gracefully by polling. No commented-out code, no placeholder implementations, no unnecessary abstractions. Ship it.
