# Session Log
## Session 149 — 2026-03-09 11:00 UTC (Monday Late Morning)
- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~11d uptime
- **Staging:** v0.5.2 ✅ commit 5a7ee79 (60+ commits ahead of prod)
- **K8s cluster:** All 3 nodes Ready
- **Support:** Zero tickets
- **Completed:**
1. **Type safety: eliminate all `catch(err: any)` (TDD)** — Replaced all `catch (err: any)` with `catch (err: unknown)` across 8 source files (db.ts, index.ts, convert.ts, demo.ts, billing.ts, health.ts, templates.ts). Added `errorMessage()` and `errorCode()` helpers in utils/errors.ts for safe property access. Updated `isTransientError()` to require Error instances (was accepting plain objects — type-unsafe). Typed `transportConfig` in email.ts as `SMTPTransport.Options` (was `any`). Typed `databaseStatus` in health.ts. Typed `margin` param in convert.ts. Changed `params` in `queryWithRetry` from `any[]` to `unknown[]`. 19 new TDD tests. Updated existing tests to use proper Error instances. Commit 5a7ee79.
2. **Sub-agent platform issue** — Sub-agent spawn failed instantly (same issue as sessions 142-148). Implemented changes directly.
- **Remaining `any` in production code:** Only in `templates.ts` (dynamic user JSON data — intentional) and one comment in `types.ts`.
- **Total tests:** 598 (all passing, 0 errors), 52 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. 60+ commits ahead with 598 tests. Awaiting CI runner restoration + investor approval for production tag.
