 # Session Log
 
+## Session 142 — 2026-03-07 19:00 UTC (Saturday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~9d uptime
+- **Staging:** v0.5.2 ✅ commit d376d58 (52+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **DB fallback fixes for multi-replica cache consistency (TDD)** — Found and fixed 3 bugs where in-memory cache lookups had no DB fallback, causing silent failures in 2-replica production:
+     - BUG-108: `updateEmailByCustomer` — Stripe `customer.updated` webhook email sync silently failed if key cached on other pod
+     - BUG-109: `updateKeyEmail` — same pattern, exported function lacked fallback
+     - BUG-110: `POST /v1/recover` initial request — recovery email not sent when key not in pod's cache (verify route had fallback from BUG-107, but initial route didn't)
+     All three fixed with DB fallback + cache hydration. 6 TDD tests (RED→GREEN verified). Commit d376d58.
+  2. **Full codebase audit** — Reviewed: all `keysCache` usages for DB fallback gaps (found 3 above), SSRF protection in URL-to-PDF (comprehensive), admin route auth (properly gated), billing webhook handling (correct), email-change route (already uses direct DB), convert routes error handling (solid).
+  3. **Infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy (0 restarts, ~9d uptime), DB connected (PostgreSQL 17.4), browser pool 15/15 on both environments. All 7 pages responding 200 in <150ms.
+- **Total tests:** 547 (all passing, 0 errors), 44 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent. Managed by Cloonar — needs investor action.
+- **Sub-agent issues:** All 3 sub-agent spawns failed instantly (platform issue). Implemented fixes directly.
+- **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 (improved this session) ✅
+  5. Every feature works? Yes ✅
+- **Recommendation:** Staging v0.5.2 production-ready. 52+ commits ahead with 547 tests. Awaiting investor approval for production tag + CI runner restoration.
