+## S51 (2026-06-08) — P11-C Vehicle+Driver catalogs + gotcha #57 ext (HMW-mode ON · product feature · deployed prod)
+
+**User: `/session-start` → "P11-C Vehicle+Driver" → "làm đi / chạy luôn cho nhanh". HMW fan-out, ship to prod.**
+
+**Done (commit `30a99aa` → Gitea Run #371 PASS ~4m18s, verified prod):**
+- **Mig 44 `AddVehicleAndDriverCatalogs`** — extend HrmConfigs +2 declarative kind (Vehicle/Driver), 2 catalog table filtered-unique day-1. BE Region 5/6 CRUD + Controller +2 route (GET public/write Admin) + MenuKeys +All (auto perm) + DbInitializer idempotent seed. FE KIND_CONFIG +2 ×2 app SHA256 mirror + 4-place (`:kind`-driven, no new route). Tables 91→**92** (sys.tables ground-truth — narrative "93" was +1 drift).
+- **Mig 45 `FilterHrmCatalogUniqueIndexesByIsDeleted`** (bundled gotcha #57) — LeaveType+ShiftPattern+**OtPolicy** filtered (3 HRM catalog; OtPolicy missed in "2 catalog" backlog, caught via grep). +5 test-before (181→**186** RED→GREEN).
+- **reviewer caught 1 MAJOR** → fixed: Driver FE↔BE required-field mismatch (root = inconsistent em-main brief BE-required vs FE-optional).
+- **cicd Run #371:** bundle admin `Cg9mvltU`/user `YgqDvsqr`, 5 idx filtered `([IsDeleted]=(0))` live, smoke 200, /hrm-configs/{vehicles,drivers} wired.
+
+**🔴 NEXT SESSION:**
+- **gotcha #57 EXT (worktree session đang chạy):** Department/Supplier/Project (Master) → Mig 46 (3 idx, confirmed-reachable). Merge khi xong — nó tạo Mig 46; main KHÔNG tạo migration nào nữa → no conflict, chỉ cần sequence đúng.
+- **RAG/Qdrant DOWN:** restart `rag-infra.ps1 -Action ensure` (AI_INFRA repo) → verify `list_projects`. RAG re-index S42-S51 stale (AI_INFRA op).
+- **AI_INFRA-side carry-over:** `/check-email se` pull S50 handshake.
+- **Product (anh pick):** P11-D ItTicket SLA / P11-E AttendanceReport+OtPolicy multiplier / P11-F MaTicket / Phase 9 Ops.
+- **Doc backlog (low):** STATUS/HANDOFF over-tiering (re-tier) · schema-diagram §16+ Mig 27-45 gap · agent baselines stale (reviewer 130-test/investigator counts → monthly 2026-07-01).
