 # Session Log
 
+## Session 155 — 2026-03-10 13:00 UTC (Tuesday Afternoon)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~12d uptime
+- **Staging:** v0.5.2 ✅ commit 25cb5e2 (67+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Refactor: Extract buildPdfOptions in browser.ts (TDD)** — Extracted shared PDF options construction into `buildPdfOptions()` function, eliminating duplicated option-building logic between `renderPdf` and `renderUrlPdf`. 5 TDD tests added. Commit 4e00feb.
+  2. **Refactor: Extract findKeyInCacheOrDb in keys.ts (TDD)** — Extracted shared DB fallback + row-mapping logic into `findKeyInCacheOrDb(column, value)` helper. Refactored `downgradeByCustomer`, `updateKeyEmail`, `updateEmailByCustomer`, and `findKeyByCustomerId` to use it, eliminating ~60 lines of duplicated code. 3 TDD tests added. Commit 25cb5e2.
+- **Total tests:** 636 (all passing, 0 errors), 58 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. 67+ commits ahead with 636 tests, zero TS errors. Awaiting CI runner restoration + investor approval for production tag.
