 # Session Log
 
+## Session 137 — 2026-03-06 19:00 UTC (Friday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~8d uptime
+- **Staging:** v0.5.2 ✅ commit b964b98 (46+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Codebase audit — multi-pod cache consistency** — Identified two bugs where in-memory cache-only lookups silently fail in multi-replica deployments.
+  2. **BUG-106 fix (TDD): downgradeByCustomer DB fallback** — `downgradeByCustomer()` now queries the DB when cache misses, preventing canceled Stripe customers from retaining Pro access. Cache hydrated on fallback path. 2 TDD tests added.
+  3. **BUG-107 fix (TDD): recover route DB fallback** — `POST /v1/recover/verify` now falls back to DB when in-memory cache doesn't contain the email. Prevents silent recovery failures across pods. 2 TDD tests added.
+  4. **Infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy, DB connected (PostgreSQL 17.4), browser pool 15/15.
+- **Total tests:** 520 (all passing, 0 errors), 38 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent. Managed by Cloonar — 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 — now with DB fallback across pods ✅
+  5. Every feature works? Yes ✅
+- **Recommendation:** Staging v0.5.2 production-ready. 46+ commits ahead with 520 tests. Awaiting investor approval for production tag.
