[CLAUDE] Office: IT staff tự reassign ticket — authz Admin-OR-IT + capability endpoint (S54)
- BE: GetAssignableItStaffQuery {canReassign,staff} capability endpoint + AssignItTicketHandler authz Admin-OR-dept-IT (Forbidden) + assignee-must-IT (Conflict); controller /assign hạ [Authorize(Roles=Admin)]→[Authorize] (handler enforce fine-grained data-driven)
- FE: fe-admin + fe-user ItTicketsPage SHA256-identical (reverse S53 divergence), nút gate by canReassign, dropdown từ /assignable-staff (không /users)
- Test: +13 authz guard (203→216 PASS), reviewer PASS (role-string Admin chain-verified real)
- No migration (DepartmentId reuse), no menu change

# Implementer-Backend Agent — Persistent Memory
> **Persistent diary cross-session.** Auto-injected first ~200 lines at spawn (L1 HOT).
> Update BEFORE every stop. Tiered Memory v1: L1 HOT soft-cap ~30KB · L2 `archive/` on-demand · L3 RAG `search_memory` just-in-time. Keep entry ≤ 1.5K chars (gotcha #53).

## 🎯 Role baseline
WRITE specialist .NET backend SOLUTION_ERP (`Domain+Application+Infrastructure+Api`). Case 1+2+3+5 only. Tools: Read, Edit, Write, Bash, Skill, Grep, Glob + 5 RAG MCP. Skills: `ef-core-migration` + `permission-matrix` + `contract-workflow` + `form-engine`. Output: commits + verify report.
## 🚫 Split boundary (S39) + auto-refuse
- ✅ MINE: `src/Backend/SolutionErp.{Domain,Application,Infrastructure,Api}/**`
- ❌ NOT: `fe-*/**``implementer-frontend` · `tests/**``test-specialist` · schema/UX/architecture decision → em main
- **REFUSE if ANY:** 1 schema design (FK/nullable/discriminator) · 2 UX flow · 3 cross-stack >2 layer · 4 bug fix reasoning chain · 5 integration multi-component · 6 <30min trivial · 7 first-time no precedent · 8 spec ambiguity >20%
---
## 📋 BE Patterns proven (apply confidently)
### Pattern 1: Per-chunk discipline A-E
A Domain+Mig (3-file) · B Application CQRS (Command/Query/Validator) · C Service (workflow logic) · D Api Controller · E commit. Build+test pass mỗi chunk. Commit `[CLAUDE] <scope>: Chunk X — ...` + Co-Authored-By Claude Opus 4.8 (1M context).
### Pattern 2: EF migration 3-file rule (gotcha #17 — BẮT BUỘC commit đủ)
`{TS}_{Name}.cs` + `.Designer.cs` + `ApplicationDbContextModelSnapshot.cs`. Path `src/Backend/SolutionErp.Infrastructure/Persistence/Migrations/`.
```bash
dotnet ef migrations add <Name> --project src/Backend/SolutionErp.Infrastructure --startup-project src/Backend/SolutionErp.Api
# Apply Dev (runtime): --connection "Server=(localdb)\MSSQLLocalDB;Database=SolutionErp_Dev;Trusted_Connection=True;TrustServerCertificate=true"
# Apply Design (ef default): không cần --connection
```
Apply BOTH DB per `feedback_designtime_runtime_db`.
### Pattern 3: Audit reuse trước khi clone (`feedback_audit_reuse_before_clone`)
"Clone X→Y": grep discriminator (`ApplicableType`/`Type`/`Kind`) → check Service/Handler hardcode → check FE route dynamic → check menu key (BE const + FE menuKeys.ts thường thiếu) → default reuse 80%, chỉ thêm menu key + sample seed.
### Pattern 4: Service hook vs CRUD endpoint cho derived state (`feedback_service_hook_vs_endpoint`)
State X derived của action Y → UPSERT trong handler Y, KHÔNG endpoint /X riêng. VD `ApproveV2Async` UPSERT LevelOpinion qua match `ApproverUserId==actorUserId` (fallback first khi Admin override). 0 endpoint mới.
### Pattern 7: Per-NV admin opt-in flag (Mig 29/30/31)
`ApprovalWorkflowLevel` +1 `bool` DEFAULT 0 (opt-in). EF `HasDefaultValue(false)`. DTO extend. FE Designer checkbox inline. Scope role-context → table mapping (Approver→Level table carry ApproverUserId FK, Drafter→User table direct, `feedback_per_nv_permission_scope`). Reusable F5/F6.
### Pattern 8: Tách endpoint riêng cho narrow scope
1 action 2 scope theo role → tách endpoint (guard tự nhiên + audit). VD Drafter `UpdatePeDraft` (Section 1 rộng, phase Nháp/Trả lại) vs Approver `AdjustBudget` (Budget rows hẹp, phase Đang duyệt + per-NV flag). KHÔNG default expand Drafter scope cho Approver.
### Pattern 9: Defense-in-depth FE+BE guard pair
UI `disabled={!canX}` + BE helper `EnsureCanXAsync(id, userId)` throw 403 (NOT inline handler) — tránh forge qua DevTools. Bất kỳ action sensitive (approve/reject/adjust).
### Pattern 12-bis: Cross-module entity cookie-cutter mirror (S29 Plan B, proven 3×)
"Mirror entity X từ module A→B": 6 file MAX — (1) new entity `Domain/<Mod>/<Entity>.cs` rename FK+nav · (2) parent +nav collection · (3) IApplicationDbContext +DbSet · (4) ApplicationDbContext +`Set<X>()` · (5) new `<Entity>Configuration.cs` (separate file mirror PE, NOT inline) · (6) `dotnet ef migrations add` 3-file. AuditableEntity inherit. FK: parent Cascade + 3rd-party Restrict + User skip-nav (denorm `<Type>ByFullName`). Apply 2 DB. ⚠️ Catalog-mega variant (S35 HrmConfig): HRM entities KHÔNG có global `HasQueryFilter(!IsDeleted)` (vs Master) → list query MUST `.Where(!IsDeleted)` thủ công (verify `Grep HasQueryFilter` Configurations FIRST). Validator MaxLength MATCH EF config (verify source-of-truth, KHÔNG trust spec blind).
### Pattern 12-ter: N≤7 satellite CRUD scaffold same parent (S34, `feedback_within_module_n_satellite_scaffold`)
"N satellite cùng parent" → 1 mega file `<Parent>SatelliteFeatures.cs` N region cookie-cutter (Create verify parent `AnyAsync` → Update `FirstOrDefault !IsDeleted` → Delete soft `IsDeleted+DeletedAt+DeletedBy` ICurrentUser) + 1 Controller extend (3 verb × N). Endpoint verify `parentId==cmd.ParentId` BadRequest mismatch. Per-action policy override class-level Read.
### Patterns moved (split S39)
- **FE patterns** (5 mirror 2-app · 6 VND helpers · 13 read-only Designer · 14 Tailwind JIT palette · 15 rowSpan builder · **16-bis 4-place mirror**) → `implementer-frontend` MEMORY (seeded).
- **Test patterns** (10 reflection authz · 11 test infra helper · 12 InternalsVisibleTo) → `test-specialist` MEMORY (seeded).

## ⚠️ Anti-patterns (DO NOT)
1. ❌ Skip MEMORY · 2. ❌ `--no-verify` · 3. ❌ `git add -A`/`git add .` (specific files) · 4. ❌ Touch outside spec scope · 5. ❌ Push remote autonomous (em main pushes) · 6. ❌ Modify `SolutionErp.slnx` autonomous · 7. ❌ Lower bar match em main (Smart Friend) · 8. ❌ Proceed khi ambiguity >20% → REFUSE

## 🧠 SOLUTION_ERP BE conventions (S40)
- **BE .NET 10:** PascalCase entities + DTO records + command names. CQRS+MediatR+FluentValidation+AutoMapper. Repository qua `IApplicationDbContext`. `GlobalExceptionMiddleware` → ProblemDetails (NO try-catch controllers).
- **State S53:** 47 mig (last `FilterMasterCatalogUniqueIndexesByIsDeleted` Mig 47, index-only) · 93 SQL tables · ~224 endpoints · 203 test (58 Domain + 145 Infra, test-specialist owns). Phase 9 UAT skip per chunk (`feedback_uat_skip_verify`).
- **Build:** `dotnet build SolutionErp.slnx` clean 0 err. Commit `[CLAUDE] <scope>: <msg>` + Co-Authored-By Claude Opus 4.8 (1M context).
- **Pin (KHÔNG `*`/latest):** MediatR `12.4.1` (14 fail DI) · Swashbuckle `6.9.0` · Node CI `20.x` · LibreOffice `25.8.6` · @microsoft/signalr `8.0.7`.

Mig diff CLEAN: Up=3×DropIndex+3×CreateIndex filtered, Down=3×reverse unfiltered (no drift, no extra table/col). Master entities HAVE global `HasQueryFilter(!IsDeleted)` (unlike HRM) — app-check `db.X.AnyAsync(Code==req.Code)` filters soft-deleted → passed; then bare DB index counted it → UNIQUE violation 500. Filter aligns DB index with app-check. **Mig 46 local catch-up:** S52 left local LocalDB stuck at Mig 45 (prod had 46 via CI, local gap). `database update` to BOTH DBs applied Mig 46 (`AddSlaFieldsToItTicket`) THEN Mig 47 — residual closed.
