# Review by Linus Torvalds (Round 2)

## Review Complete — Linus Torvalds, Round 2

**All 182 frontend tests pass. All 234 relevant Python tests pass. No TODOs, no secrets, no placeholder code.**

VERDICT: **approve**

FINDINGS:
- **[web/src/components/PhaseTimeline.tsx]**: Mutable `visibleIndex` counter during render is fragile; should be pre-computed in a `useMemo` for safety under concurrent rendering
- **[web/src/util.ts]**: Six switch-statement color helpers are verbose lookup tables; could be `Record<string, string>` maps
- **[web/src/pages/Dashboard.tsx + DaemonHealthBanner.tsx]**: `capitalize()` duplicated in two files; extract to `util.ts`
- **[src/colonyos/daemon.py]**: `_notification_thread_locks` dict grows without bound; add cleanup when items reach terminal state
- **[src/colonyos/daemon.py]**: Bundled refactors (worktree tri-state, notification locking, circuit breaker messaging) ideally separate commits for bisectability

SYNTHESIS:
This is a solid, workmanlike implementation. All 10 functional requirements are met. The data structures are correct and the component hierarchy is obvious — no pointless abstraction layers, no framework-of-the-week nonsense. The daemon embedding is properly isolated with exception handling that can't crash the host process. The security fixes from round 1 (default-off write mode, masked tokens, rate limiting, CORS validation, auth on healthz) are all correctly implemented. The worktree tri-state refactor is a genuine safety improvement with fail-closed semantics — the old code silently assumed "clean" when `git status` failed. Test coverage is thorough at both layers. The five findings are all non-blocking style/maintenance issues. The code does what it says it does, and it does it simply. Approved.
