 # Session Log
 
+## Session 147 — 2026-03-08 19:00 UTC (Sunday Evening)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~10d uptime
+- **Staging:** v0.5.2 ✅ commit a60d379 (58+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Type safety: AuthenticatedRequest interface (TDD)** — Eliminated `as any` casts for `apiKeyInfo` across the codebase. Created `src/types.ts` with `AuthenticatedRequest` interface extending Express `Request`. Updated auth.ts, usage.ts, pdfRateLimit.ts middleware and all index.ts route handlers (usage/me, admin auth, admin usage, admin cleanup, concurrency) to use typed casts instead of `any`. Also typed usage middleware params from `any` to proper Express types. 4 TDD tests added. Commit a60d379.
+- **Total tests:** 566 (all passing, 0 errors), 50 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. 58+ commits ahead with 566 tests. Awaiting CI runner restoration + investor approval for production tag.
