[CLAUDE] Docs: S58 closeout — lock fix prod-verified Run #382 + S57bis flush + gotcha #59/#60 + harvest on-behalf

- STATUS/HANDOFF: thêm S57bis + S58 (2-session gap S57bis đóng vội), counts
  re-ground (Mig 49 · test 240 · gotcha 60 · menu 57 · bundle CP4CB1ym/BmZ3VHnm
  curl-verified · RAG 2420). Ops S56 "gán user IT" RESOLVED (nv.cao/nv.truong
  sống lại nhờ password fix).
- gotchas: #59 (PS5.1 git commit -F, residual S57bis) + #60 NEW (Identity seed
  CreateAsync silent-fail vs prod RequiredLength=12 — population Dev ≠ prod,
  dump data thật trước lock/seed-by-email) + checklist 31/32.
- agent-memory: cicd Run #381 (residual) + #382 · 4 spawn-record on-behalf
  (database-agent/impl-backend/impl-frontend/reviewer — H2 Coverage 4-MISS đóng)
  · investigator-codebase recon · 2 monitor RE-REPORT entries.
- skills: ef-core +row Mig 49 (49 mig ×5 chỗ) · README + dep-audit count sync.
- CLAUDE.md root: Mig 49 + test 240 + gotcha 60 + schema-ref 32-49.

 ## Log
 - **S52 (2026-06-08):** Seeded (em main, adap-apply database-agent). Roster 10→11. Nấc executed-file. CHỜ restart + spawn-test → verified-runtime.
 - **S56 (2026-06-09) — pre-golive verify (2nd real spawn, verified-runtime ✓):** Schema/Mig integrity P11 + S55 master-data = SOLID. Mig 42-48 applied IDENTICALLY Dev+Design+prod `.\SQLEXPRESS` (48 mig / 92 tables, **NO S53-style unapplied-local drift**); 0 pending model-snapshot diff; **9 gotcha-#57 filtered-unique** confirmed BOTH EF config (HasFilter×13) AND DB (`filter_definition=([IsDeleted]=(0))`) incl Vehicle/Driver day-1; FK đúng (LeaveBalance→LeaveType Restrict + UNIQUE(User,Type,Year); 4× LevelOpinions Cascade(parent)/Restrict(Level)+UNIQUE composite; ItTicket SLA nullable). **DB11 FAIL (1 major, fast-follow KHÔNG blocker):** `LeaveBalance.UsedDays += NumDays` @ `LeaveOtApprovalFeatures.cs:361-386` chạy bare SaveChanges (no tx / no RowVersion / READ COMMITTED) → concurrent double-approve lost-update. **S43 gap STILL OPEN.** Fix-pattern sẵn repo: Serializable tx (codegen `:34`) HOẶC RowVersion+retry (1 mig). Low-prob ~30 user, recoverable Admin Adjustment. Tag [s56, pre-golive-verify, schema-pass, db11-lostupdate-open].
+- **S57bis (2026-06-11) — PE gắn Hạng mục design (3rd real spawn, DELIVERED — on-behalf em main ghi hộ, H2-proposed):** Introspect LocalDB → design `PurchaseEvaluations.WorkItemId Guid?` scalar **loose-Guid + IX, KHÔNG FK vật lý** — nhất quán convention PE (ProjectId/SelectedSupplierId đều loose; duy nhất ApprovalWorkflowId có FK). Guard = validator + handler mirror S43 FK-invariant. KHÔNG đụng CodeSequences (mã phiếu giữ `PE/{YYYY}/{A|B}/{Seq}`). LEARNED: PE FK-convention map (loose-Guid là norm module này — FK vật lý là exception). SURPRISE: WorkItems = catalog GLOBAL (KHÔNG ProjectId) → 2 dropdown độc lập; "Dự án (năm) – Hạng mục" chỉ là chuỗi ghép hiển thị, không ràng buộc quan hệ. Ship: Mig 49 deploy Run #381 prod-applied. Tag `[s57bis, mig49-design, on-behalf]`.
