[CLAUDE] Docs: S53 closeout — gotcha #57 EXT Master (Mig 47) + P11-D/E + database-agent verified-runtime + doc-drift

Session 53 closeout (HMW-mode ON, 'làm hết' full close). Code already shipped in 44b9e54 (Mig 47, Run #260) + dbf6648 (C+D, Run #261), both prod-verified.

- STATUS/HANDOFF: S53 entry (mig 46->47, test 200->203, menu +Off_AttendanceReport, bundle admin DfCfHUE9, database-agent verified-runtime).
- Doc-drift E (H1 top-5): ef-core skill 43->47, agents/README roster 10->11 + plugin nac, CLAUDE.md root 45->47 mig + 186->203 test, docs/CLAUDE.md 56->57 gotcha + 91->92 ERD.
- adap-report: database-agent executed-file -> verified-runtime (spawn-test caught Mig 46-unapplied-local).
- session log 2026-06-08-S53 + 4 agent diaries (S53 work).
- Memory: +project_database_agent_verified_local_drift (user-memory, outside repo).

+- **2026-06-08 (S52 P11-D Master gotcha #57 EXT) [test-before · 3 RED LIVE]:** +3 test `tests/.../Application/MasterCatalogFilteredUniqueTests.cs` (run `--filter MasterCatalogFilteredUnique` → Failed 3/Passed 0). Department+Project+Supplier `.IsUnique()` BARE (Dept cfg:18 / Proj:19 / Supp:24) chưa `[IsDeleted]=0` — cùng class gotcha #57. Mirror EXACT GROUP B HrmConfigFilteredUniqueTests: seed row `IsDeleted=true` slot Code="DUP1" → `Create{Dept|Project|Supplier}CommandHandler(db)` cùng Code → assert `NotThrowAsync` + active==1 + `IgnoreQueryFilters` all==2. **3 RED** = `DbUpdateException → SQLite Error 19 UNIQUE constraint failed: {Departments|Projects|Suppliers}.Code` (app-check `AnyAsync(Code==X)` chạy QUA HasQueryFilter → loại soft-deleted → PASS → Add+SaveChanges → DB UNIQUE bare đếm cả row xoá → throw). NOT test lỗi — REPORTED em main fix migration `.HasFilter` 3 config → flip GREEN. **⚠️ all-count PHẢI `IgnoreQueryFilters()`** (khác HRM ref dùng raw `Count(Code==X)` trên DbSet đã có HasQueryFilter → trả 1 not 2 = sai; tôi sửa = active-count plain DbSet, all-count IgnoreQueryFilters). 3 handler clean `(IApplicationDbContext db)` 1-dep. KHÔNG đụng Configuration/Domain/migration. Tag [s52, p11-d, gotcha-57, master-catalog, filtered-unique, test-before, RED].
 - **2026-06-08 (S52 P11-D Wave2 round-robin + SLA-due) [proxy by em main: agent killed session-limit trước MEMORY step]:** +9 test `ItTicketAssignSlaTests.cs` → **200 PASS** (Infra 133→142). **Round-robin:** seed Department Code="IT" + 2 user A/B `IsActive` trong IT + A có 1 ticket Open → Create → assign **B** (load 0<1); tie A=B → `ThenBy(Id)`; edge no-dept-IT / no-user-IT → unassigned; user ngoài IT hoặc `IsActive=false` KHÔNG assign. **SLA-due:** Priority Urgent→+4h / High→+8h / Medium→+24h / Low→+72h (assert `e.SlaDueAt==CreatedAt+SlaWindow[priority]`). **Regression P11-F:** create vẫn gen `^IT/\d{4}/\d{3}$`. `ItTicketSlaJob` BackgroundService SKIP unit-test (breach-query inline, khó test trực tiếp — REPORTED). Baseline 191→**200** (58 Domain + 142 Infra). Tag [s52, p11-d, round-robin, sla-due, regression].
 
 - **2026-06-08 (S52 P11-E + P11-F WorkflowApps/Attendance test-after):** +5 test → **191 PASS** (Infra 128→133). 2 file `tests/.../Application/`: **ItTicketCodeGenTests** (3 — MaTicket regex `^IT/\d{4}/\d{3}$` + sequential 001→002 cùng prefix `IT/{year}` LastSeq++ + per-year-prefix 2027 reset 001) + **AttendanceReportTests** (2 — full aggregate day-type/weighted + DepartmentId filter). **⭐ Serializable-on-SQLite GOTCHA = NON-ISSUE (confirmed):** `WorkflowAppCodeGen.GenerateMaDonTuAsync` dùng `BeginTransactionAsync(IsolationLevel.Serializable)` chạy SẠCH trên SQLite — provider map isolation level gracefully (no throw), format+seq+per-year đều hold KHÔNG cần try/skip. Đã proven sẵn bởi WorkflowAppApproveV2Tests (DT/LR path). Handler `CreateItTicketHandler(db, cu, clock)` = 3 dep MediatR. **Day-type test pattern (P11-E core):** holiday check chạy TRƯỚC weekend/weekday → seed 2026-06-01 (thứ Hai) vào holidaySet → assert phân **Holiday** dù là weekday (override day-of-week). Holiday.Date=DateOnly → `BuildHoliday` dùng `DateOnly.FromDateTime`. OtWeighted = 2×1.5+3×2.0+1×3.0=12.0m. DepartmentId filter: seed 2 Department row + 2 user khác dept → query deptA chỉ trả 1 row (handler join Users `u.DepartmentId==deptId`, userMeta dùng `DefaultIfEmpty` nên dept row optional nhưng seed cho DepartmentName assert). No prod bug. **⚠️ MSBuild OOM** chạy full parallel → dùng `-maxcpucount:1 -p:BuildInParallel=false` (env resource, KHÔNG test fail).

 - **2026-06-08 (S51 P11-C HMW Wave2 filtered-unique gotcha #57):** +4 test `tests/.../Application/HrmConfigFilteredUniqueTests.cs` → **185 total = 183 PASS + 2 RED** (Infra 123→127). Mirror HolidayTests Case 7 (seed soft-deleted Code-slot → Create same Code → assert success + active==1 + all==2). **2 GREEN** Vehicle+Driver (Mig 44 config ĐÃ filtered → 2 catalog mới đúng). **2 RED INTENTIONAL = gotcha #57 REPRODUCED** (test-before): `CreateLeaveType_OnSoftDeletedCodeSlot...` → `SQLite Error 19 UNIQUE constraint failed: LeaveTypes.Code` + `CreateShift_OnSoftDeletedCodeSlot...` → `ShiftPatterns.Code` (bare `.IsUnique()` đếm cả row soft-deleted; handler app-check `!IsDeleted` PASS → Add+SaveChanges → DbUpdateException). NOT test lỗi — REPORTED em main fix Mig 45 `.HasFilter("[IsDeleted]=0")` cho 2 config → flip GREEN. **⚠️ Soft-delete trong test (giống Holiday):** AuditingInterceptor (prod soft-delete Deleted→Modified+IsDeleted=true) KHÔNG wire trong SqliteDbFixture → `Remove+SaveChanges` = HARD delete (không test được). PHẢI seed row `IsDeleted=true` thủ công để mô phỏng slot bị chiếm. Handlers chỉ cần IApplicationDbContext → `new CreateXxxHandler(db)`. Tag [s51, p11-c, gotcha-57, filtered-unique, test-before].
-- **2026-05-30 (S42 P11-A Wave4):** +11 test `tests/.../Application/WorkflowAppApproveV2Tests.cs` → **141 PASS** (Infra 72→83). LeaveRequest 8 case full (Submit happy/guard×2, Approve advance/terminal/UPSERT-invariant/forbidden/empty-comment-placeholder, Reject→TuChoi, Return→TraLai+RejectedFromStatus) + OtRequest smoke (submit→approve single-level→DaDuyet). **No prod bug** — LeaveOt ApproveV2 wire correct, all PASS first run. **NEW Pattern:** WorkflowApps handlers = CQRS MediatR (KHÔNG service) → instantiate handler trực tiếp `new ApproveLeaveRequestHandler(db, AsUser(u), clock).Handle(cmd,ct)`, chỉ 3 dep (IApplicationDbContext + TestCurrentUser + FixedDateTime) — nhẹ hơn 6-dep Contract service. MaDonTu format "DT/LR/2026/001". Gap #4 (Workflow Apps) PARTIAL done — Travel/Vehicle mirror pending. ⚠️ Lesson: CWD drift (fe-user) → ghi MEMORY nhầm path, em main relocate. Verify CWD root trước Write memory.
 - **2026-05-30 (S43 P11-B Wave3 LeaveBalance):** +8 test `tests/.../Application/LeaveBalanceTests.cs` → **152 PASS** (Infra 86→94). Deduction hook (ApproveLeaveRequestHandler terminal) full: deduct single-level (create row from DaysPerYear), only-at-terminal multi-level (advance no-deduct + 1× terminal), accumulate UPSERT (5+2=7 no new row), negative allowed (Used20>Entitled12 → Remaining−8 no throw), Reject+Return no-deduct (split 5a/5b), GetMyLeaveBalances lazy synth (2 active type filter inactive), AdjustLeaveBalance upsert. **⚠️ FOUND + FIXED 2 pre-existing RED** in S42 template (`Approve_LastLevel_TransitionsToDaDuyet` + `Approve_EmptyComment_StoresPlaceholder`): Wave 1 deduction hook (uncommitted, prod) làm terminal insert LeaveBalance FK→LeaveTypes Restrict FAIL vì BuildLeave dùng `LeaveTypeId=Guid.NewGuid()`. **NOT prod bug** (prod đơn luôn pin LeaveType thật) — fix tại test: BuildLeave +optional leaveTypeId, seed LeaveType ở 2 test đó. Baseline thật trước S43 = 142-pass/2-RED (KHÔNG phải 144-green). REPORTED em main.
 - **2026-06-01 (S45 HRM coverage gaps + Holiday drift) [em main proxy]:** +27 test → **181 PASS** (Infra 96→123). 3 file: HrmConfigHolidayTests (7 — composite UNIQUE Create/Update, ⭐self-update giữ key đổi Name no-false-positive, soft-delete exclusion) + EmployeeSatelliteTests (10 — 5× FK-invariant parent `AnyAsync(!IsDeleted)` guard + soft-delete + cascade-non-behavior Case5 + EF model `DeleteBehavior.Cascade` config assertion) + AuthorizePolicyRegressionTests extend (10 — HrmConfigs bare-`[Authorize]`+writes `Roles=Admin`; Employees class-`Policy=Hrm_HoSo.Read`+per-action). **FOUND drift** (test theo CODE = single source): Holiday DB UNIQUE (Year,Date) unfiltered vs handler `!IsDeleted` → recreate-on-soft-deleted-slot `DbUpdateException(500)`. REPORTED → em main fixed Mig 43 `.HasFilter("[IsDeleted]=0")` (Case 7 flipped assert SUCCESS). New pattern: EF model-metadata assertion `db.Model.FindEntityType(typeof(X)).GetForeignKeys()...DeleteBehavior` lock schema intent. ⚠️ gotcha #57 backlog: LeaveType.Code + ShiftPattern.Code vẫn unfiltered.
