 ### S3 — TASKS.md revert
 
 TASKS.md had reverted to S1 state (only PLAN-001 done) despite S2 completing 5 tasks. Root cause: S2 doc commits were on main but TASKS.md edits were local and lost when worktree workers caused git state issues. Rewrote TASKS.md from scratch in S3.
+
+### S4 — 2026-02-27
+
+1. **Completed tasks**: SS-WS-003 (already in main), SS-UI-001 (PR #545 merged by S3 worker), SS-ORCH-002 (PR #547 merged by worker + PR #548 test fix + PR #549 CORS fix by orchestrator), SS-VER-001 (full site verification + deploy)
+2. **Key findings during verification**:
+   - WebSocket test failure: PR #547 added `withCredentials: true` but test expected old options. Fixed in PR #548.
+   - WebSocket CORS: Gateway used `process.env.WEB_URL ?? "http://localhost:3000"` for CORS origin. WEB_URL not set in prod, causing localhost CORS rejection. Fixed in PR #549 to use `getTrustedOrigins()` matching main API.
+   - SS-WS-003 was already in main from S2 worker that co-committed with favicon fix. PR #546 closed as redundant.
+3. **Deployment**: Portainer stack 121 (mosaic-stack) redeployed twice — first for PR #548 merge, second for PR #549 CORS fix.
+4. **Smoke test results**: All 8 key pages return 200. Chat WebSocket connected (no more "Reconnecting"). Favicon valid RGBA ICO. No CORS errors in console. Only remaining errors are orchestrator 502s (expected — service not active in prod).
+5. **Variance**: SS-ORCH-002 estimated 15K, used ~25K (67% over) due to CORS follow-up fix discovered during verification.
+6. **Total mission PRs**: 13 code PRs + 1 doc PR = 14 merged.
