 # Session Log
 
+## Session 143 — 2026-03-08 07:00 UTC (Sunday Morning)
+- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~10d uptime
+- **Staging:** v0.5.2 ✅ commit 2793207 (53+ commits ahead of prod)
+- **K8s cluster:** All 3 nodes Ready
+- **Support:** Zero tickets
+- **Completed:**
+  1. **Dead code removal: token-based verification system (TDD)** — Identified and removed entire unused token-based verification subsystem. The old system loaded ALL verifications into memory on startup (unbounded growth), used in-memory-only cache (multi-replica unsafe), and was never triggered by any user flow (email only sends 6-digit codes, not token URLs). Removed:
+     - `verificationsCache`, `loadVerifications()`, `verifyToken()`, `verifyTokenSync()`, `createVerification()` from verification.ts
+     - GET `/verify` route and `verifyPage()` helper from index.ts
+     - `loadVerifications()` call from startup
+     - `createVerification()` call from signup route
+     - Updated test mocks in setup.ts and signup.test.ts
+     - Active 6-digit code system preserved intact
+     - 12 new TDD tests added, 6 files changed, -38 net lines
+     - Commit 2793207. 559 tests passing (up from 547).
+  2. **Codebase audit** — Reviewed: npm audit (0 vulnerabilities), no TODOs/FIXMEs, all pages returning 200, Dockerfile solid, rate limiting appropriate for scale, usage middleware multi-replica limitation acceptable, API key validation timing-safe enough for hex keys.
+- **Total tests:** 559 (all passing, 0 errors), 45 test files
+- **Open bugs:** ZERO 🎉
+- **CI runner:** Still absent — push didn't trigger staging redeploy. Runner not found on k3s-mgr. Needs investor action.
+- **Recommendation:** Staging v0.5.2 production-ready. 53+ commits ahead with 559 tests. Awaiting CI runner restoration + investor approval.
