 # Session Log
 
+## Session 160 — 2026-03-11 13:00 UTC (Wednesday Afternoon)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~13d uptime
+- **Staging:** v0.5.2 ✅ healthy (CI runner absent — no auto-redeploy from push)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Dependency updates (minor/patch)** — Updated express 4.21→4.22, helmet 8.0→8.1, nanoid 5.0→5.1, swagger-ui-dist 5.31→5.32, tsx 4.19→4.21, typescript 5.7→5.9, vitest 3.0→3.2, express-rate-limit 7.5→7.5.1, @types/node 22→25, @types/express 5.0→5.0.6, @types/pg 8.11→8.18, @types/nodemailer 7.0.9→7.0.11. Zero TS errors. 663 tests passing. 0 npm audit vulns. Commit a55c306.
+  2. **Full infrastructure check** — All 7 pages return 200. Compression working (36KB→9KB gzip). Rate limit headers present. OpenAPI spec complete with 15 paths.
+  3. **Codebase review** — No TODOs/FIXMEs. Error handling consistent. Silent catches in browser.ts are intentional cleanup. All source files have corresponding tests.
+- **Not updated (major, needs migration):** Express 5, express-rate-limit 8, vitest 4
+- **Total tests:** 663 (all passing, 0 errors), 61 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent — push doesn't trigger staging redeploy. Needs investor action.
+- **Investor test:**
+  1. Would a stranger trust this with money? Yes ✅
+  2. Pod crash = data loss? No — CNPG WAL archiving + MinIO ✅
+  3. Free tier abuse? No — removed, demo rate-limited ✅
+  4. Pro key recovery? Yes — with DB fallback across pods ✅
+  5. Every feature works? Yes ✅
+- **Recommendation:** Staging v0.5.2 production-ready. 72+ commits ahead with 663 tests, zero TS errors. Awaiting CI runner restoration + investor approval for production tag.

+## Session 159 — 2026-03-11 10:00 UTC (Wednesday Late Morning)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~13d uptime
+- **Staging:** v0.5.2 ✅ healthy (CI runner absent — no auto-redeploy from push)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Periodic database cleanup (TDD)** — Added `startPeriodicCleanup()`/`stopPeriodicCleanup()` in `src/utils/periodic-cleanup.ts`. Runs `cleanupStaleData()` every 6 hours to clean expired verifications and orphaned usage rows. Previously only ran on startup — with 13d+ uptime, stale data accumulates. Uses `.unref()` to not block shutdown. Stopped during graceful shutdown before `pool.end()`. Idempotent start. 6 TDD tests (red→green verified). Commit cc7de5e.
+  2. **Full link audit** — All 7 internal pages return 200. All links on landing page verified. Examples page uses correct `docfast.dev` URLs. OpenAPI spec has 15 paths, all correct.
+  3. **Codebase audit** — No TODOs/FIXMEs. Error handling consistent. No new bugs found.
+- **Total tests:** 663 (all passing, 0 errors), 61 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent — push doesn't trigger staging redeploy. Needs investor action.
+- **Investor test:**
+  1. Would a stranger trust this with money? Yes ✅
+  2. Pod crash = data loss? No — CNPG WAL archiving + MinIO ✅
+  3. Free tier abuse? No — removed, demo rate-limited ✅

+  5. Every feature works? Yes ✅
+- **Recommendation:** Staging v0.5.2 production-ready. 71+ commits ahead with 663 tests, zero TS errors. Awaiting CI runner restoration + investor approval for production tag.
