# Session Log
## Session 125 — 2026-03-04 13:00 UTC (Wednesday Afternoon)
- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~6.7d uptime
- **Staging:** v0.5.2 ✅ updated to commit d2f819d (34 commits ahead of prod)
- **K8s cluster:** All 3 nodes Ready
- **Support:** Zero tickets
- **Completed:**
1. **BUG-100 discovery & fix (TDD)** — Found that `flushDirtyEntries()` in usage middleware wrapped all writes in a single PostgreSQL transaction with per-key try/catch. In PostgreSQL, any failed INSERT aborts the entire transaction, making the per-key error handling useless — one bad key poisons the entire batch. Sub-agent removed the transaction, each key now flushes independently with its own client. 1 TDD test added (red→green verified). Commit d2f819d.
2. **Codebase audit** — Reviewed convert routes, browser pool, PDF options validation, body size limits, error pages, security headers, demo endpoint, logger. All solid. Noted CSS reset injection in `renderPdf` as a potential UX concern (documented, not a bug — changing it could break existing users).
3. **Infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy (0 restarts, ~6.7d uptime), DB connected (PostgreSQL 17.4), browser pool 15/15. Production health endpoint confirmed v0.5.1.
- **Total tests:** 464 (all passing), 28 test files
- **Open bugs:** ZERO 🎉
- **CI runner:** Still absent. Managed by Cloonar — needs investor action.
- **Note:** Sonnet 4 512k sub-agents failing instantly (model availability issue?). Used Opus for sub-agent successfully.
- **Investor test:** All 5 checks pass ✅
- **Recommendation:** Staging v0.5.2 is production-ready with ZERO open bugs, 464 tests, 34 commits ahead. Request investor approval for production tag.
## Session 124 — 2026-03-04 10:00 UTC (Wednesday Late Morning)
- **Production:** v0.5.1 ✅ healthy, 2 replicas, 0 restarts, ~6.5d uptime
- **Staging:** v0.5.2 ✅ healthy, commit 314edc1 (33 commits ahead of prod)
- **K8s cluster:** All 3 nodes Ready
- **Support:** Zero tickets
- **Completed:**
1. **Input validation hardening (TDD)** — Added `waitUntil` validation to `validatePdfOptions` (accepts only `load`, `domcontentloaded`, `networkidle0`, `networkidle2`). Added 100KB size limits for `headerTemplate` and `footerTemplate` to prevent memory abuse. 15 TDD tests added (red→green verified). Commit 7d44524.
2. **OpenAPI schema accuracy fix (TDD)** — Fixed PdfOptions schema: format enum expanded from 6 to all 11 valid values, added missing `waitUntil` field with enum, added 100KB size limit docs to template fields. 1 TDD test added. Commit 314edc1.
3. **Infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy (0 restarts, ~6.5d uptime), DB connected (PostgreSQL 17.4), browser pool 15/15. Staging healthy internally (external returns Forbidden due to IP whitelist — expected).
- **Total tests:** 463 (all passing), 27 test files
- **Open bugs:** ZERO 🎉
- **CI runner:** Still absent. Managed by Cloonar — needs investor action.
- **Investor test:** All 5 checks pass ✅
- **Recommendation:** Staging v0.5.2 is production-ready with ZERO open bugs, 463 tests, 33 commits ahead. Request investor approval for production tag.
