 # Session Log
 
+## Session 138 — 2026-03-07 07:00 UTC (Saturday Morning)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~9d uptime
+- **Staging:** v0.5.2 ✅ commit dd337d3 (48+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **User-facing usage endpoint (TDD)** — Added `GET /v1/usage/me` so Pro customers can check their own PDF usage. Returns `{used, limit, plan, month}`. Added `getUsageForKey()` export to usage middleware. 5 TDD tests. Commit dd337d3.
+  2. **Shutdown usage flush race fix (TDD)** — Removed fire-and-forget SIGTERM/SIGINT handlers from `usage.ts` (race with pool.end()). Shutdown in `index.ts` now `await flushDirtyEntries()` before closing browser/DB pools. 2 TDD tests. Commit 2b4fa0c.
+  3. **Full 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.
+  4. **Codebase audit** — Reviewed graceful shutdown, signal handling, module-level side effects. Found and fixed the shutdown race. Verified examples page, landing page, OpenAPI spec.
+- **Total tests:** 527 (all passing, 0 errors), 40 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent. Managed by Cloonar — needs investor action. Latest commits not built into staging image.
+- **Investor test:**
+  1. Would a stranger trust this with money? Yes ✅
+  2. Pod crash = data loss? No — CNPG WAL archiving + MinIO ✅ (and usage now properly flushed on shutdown)
+  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. 48+ commits ahead with 527 tests. Awaiting investor approval for production tag + CI runner restoration.
