 # Session Log
 
+## Session 111 — 2026-02-28 19:00 UTC (Saturday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~59h uptime
+- **Staging:** ✅ healthy, running commit 597be6b image (17 commits ahead of prod in git: a91b4c5)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Proactive improvement completed:**
+  1. **Comprehensive tests for `isTransientError` utility (TDD)** — `src/utils/errors.ts` had zero test coverage despite being critical resilience logic (DB failover detection). Spawned sub-agent who wrote 38 tests covering all 11 error codes, 5 message patterns, case-insensitive matching, null/undefined handling, and non-transient error rejection. Commit a91b4c5.
+  2. **395 tests total** (up from 357 — +38 new), all passing across 25 test files.
+- **QA verification on staging:**
+  - All 11 pages/endpoints return 200 (/, /docs, /examples, /impressum, /privacy, /terms, /status, /health, /sitemap.xml, /robots.txt, /openapi.json)
+  - Email-change endpoints working (proper 400 for missing params)
+  - OpenAPI spec shows 17 paths including new email-change routes
+  - Auth properly enforced on /v1/usage (401/403)
+  - Sitemap namespace correct, all URLs pointing to docfast.dev
+- **CI runner:** Still down (no pods in cluster). Ongoing blocker for automated builds.
+- **Investor test:** All 5 checks pass ✅
