Rollout Notes

• Phase 0-3 complete — 23/23 tasks done
• Phase 4 is immediate priority — security fixes must land before any production deployment
• Phase 6 Sprint 1 can run in parallel with Phase 4 — TEC-1592, 1593, 1594 are independent
• TEC-1449 (JWT) is the single most critical fix — blocks production deployment
• TEC-1592 (Commit untracked files) blocks Agent Portal + AI + Payments — do first
• Security tasks (TEC-1449, 1451, 1452, 1453) can all run in parallel — assign to Security Engineer + Senior Backend
• TEC-1450 (Deployment Pipeline) should start after security fixes — no point deploying insecure code
• Phase 5 and Phase 6 P2 tasks are all independent — can run fully in parallel
• Critical path: TEC-1449 → TEC-1450 → TEC-1457 (security → deploy → observability)
• Feature path: TEC-1592 → TEC-1595/1596/1597 (commit → features)
