# Review by Linus Torvalds (Round 1)

VERDICT: approve

FINDINGS:
- [src/colonyos/server.py]: `serve_spa` catch-all route should validate that resolved file path stays within `_WEB_DIST_DIR` to prevent path traversal via the static file serving fallback (low severity — FastAPI's path routing limits what reaches this handler, but defense-in-depth matters)
- [web/src/pages/RunDetail.tsx]: Polling `useEffect` dependency on `data?.header.status` causes unnecessary effect re-runs; a `useRef` for the status check would be cleaner
- [src/colonyos/server.py]: Module is 214 lines vs PRD target of 200 — marginal, not a problem

SYNTHESIS:
This is a clean, well-scoped feature. The developer did the right thing: wrapped existing data-layer functions behind a thin API, kept the frontend simple, committed built assets, made the dependency optional, and wrote real tests — not just happy-path garbage. 936 tests all pass, 22 of them new, covering all API endpoints, read-only enforcement (POST/PUT/DELETE correctly return 405), path traversal rejection, empty state, and CLI flags. The architecture is straightforward: no over-engineered abstractions, no unnecessary middleware, no gratuitous state management libraries on the frontend. The one real concern is the SPA catch-all route (`serve_spa`) which doesn't validate that the resolved file path stays within `_WEB_DIST_DIR` — a `Path.resolve()` containment check should be added as a follow-up hardening task, but it doesn't block shipping since FastAPI's routing heavily constrains what reaches that handler. The code reads well, the data structures are clean, and the separation between data layer and rendering is properly maintained. Ship it.
