+## 2026-02-16 - PRD Completion Verification
+- Verified all 14 user stories (US-001 through US-014) are complete
+- All codereview benchmark deliverables confirmed:
+  - 3 tasks: cr-ghost-001 (Ghost/TS), cr-aspnetcore-001 (aspnetcore/C#), cr-calcom-001 (cal.com/TS)
+  - Infrastructure: DIR_PREFIX_TO_SUITE in generate_manifest.py and aggregate_status.py
+  - Documentation: CLAUDE.md, TASK_CATALOG.md, TASK_SELECTION.md updated
+  - Config: codereview_2config.sh with public repo mappings
+  - Validation: preflight checks pass (ALL CHECKS PASSED)
+- Files changed: prd.json (marked final 4 stories as complete)
+- **Learnings for future iterations:**
+  - When verifying completion, check both PRD status AND actual deliverables on disk
+  - Preflight validation (`python3 scripts/validate_tasks_preflight.py --suite <name>`) is the definitive completion gate
+  - Worktree names don't always match branch names — check git branch output to understand the setup
