-  1. **PDF render timing (TDD)** — Sub-agent spawned to add X-Render-Time response header and render duration logging to convert/demo routes. Changes renderPdf/renderUrlPdf return type from Buffer to {pdf, durationMs}. Agent running (Opus 4.6).
 - **Completed:**
   1. **Infrastructure health check** — All 3 K8s nodes Ready, both prod replicas healthy, DB connected (PostgreSQL 17.4), browser pool 15/15. Demo endpoint verified working on staging.
   2. **Codebase audit** — Reviewed: auth middleware (well tested), keys service (tested), rate limiting (tested), graceful shutdown (solid), error handling (consistent), 404 handling (JSON for API, HTML for browser), request ID tracking (present), OpenAPI spec (17 endpoints on staging, all with error response docs), dependency audit (0 vulnerabilities, minor updates available).
-  3. **Model issue noted** — Claude Sonnet 4.1 sub-agents failing instantly (10-13ms). Opus 4.6 works fine. Likely model availability issue.
+  3. **PDF render timing (TDD)** — Sub-agent added X-Render-Time response header and render duration logging. Changed renderPdf/renderUrlPdf return type from Buffer to {pdf, durationMs}. Updated all callers (convert, demo, templates routes). 6 new tests + 7 existing tests updated. 515 tests total, all passing. Commit pushed to main.
-- **Total tests:** 509 (all passing), 35 test files (before timing changes)
+  4. **Model issue noted** — Claude Sonnet 4.1 sub-agents failing instantly ("Unknown model"). Opus 4.6 works fine.
+- **Total tests:** 515 (all passing), 36 test files
 - **Open bugs:** ZERO 🎉
 - **CI runner:** Still absent. Managed by Cloonar — needs investor action.
 - **Investor test:** All 5 checks pass ✅
