 # Session Log
 
+## Session 161 — 2026-03-11 16:01 UTC (Wednesday Late 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
+- **Database:** 3 API keys, 1 usage record, 14 verifications (12 stale — periodic cleanup handles). Data integrity confirmed.
+- **Backups:** Daily CNPG backups running perfectly (last: 2026-03-11 03:00 UTC)
+- **Completed:**
+  1. **Express 4 → Express 5 migration (TDD)** — Upgraded express from ^4.22.1 to ^5.1.0 (resolved to 5.2.1). TDD approach: wrote 4 failing tests first (version check, async error handling), then upgraded to make them pass. All 667 tests passing (663 existing + 4 new). Zero TypeScript errors. Zero npm audit vulnerabilities. Express 5 brings native async error handling, improved performance, and stricter path matching. No breaking changes in codebase. Commit 603cbd7.
+  2. **Full infrastructure audit** — All 7 pages return 200. Security headers complete (CSP, HSTS, X-Frame, Permissions-Policy). Staging has noindex. Compression working. Rate limits verified. Demo endpoint functional (57KB PDF generated).
+  3. **Database integrity check** — All data consistent. Backups running daily at 03:00 UTC.
+- **Total tests:** 667 (all passing, 0 errors), 62 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent — push doesn't trigger staging redeploy. Needs investor action.
+- **Remaining major upgrades:** express-rate-limit 8, vitest 4 (breaking changes, future sessions)
+- **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. 73+ commits ahead with 667 tests, zero TS errors, Express 5 on latest. Awaiting CI runner restoration + investor approval for production tag.
