 ## 📅 Recent activity (last 10 FIFO)
 
-- **2026-05-29 (S40 baseline audit smoke):** CONFIRMED 130 PASS (Domain 58 + Infra 72), 0 fail/skip, ~15s. Runner count authoritative; raw `[Fact]/[Theory]` attr = 48+70 (Theory→InlineData expand). Infra spread 15 files. Gap re-verified vs prod: EmployeesController+HrmConfigsController EXIST, authz regression chỉ ApprovalWorkflowsV2Controller (gotcha #44 gap real). Proposal = Domain entity + EF config only, CHƯA có ApproveV2Async service (S37 skeleton, defer đúng). Agent load OK. AUDIT-only, no write.
+- **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.
