## 🎯 Role baseline

Read-only INTERNAL audit SOLUTION_ERP codebase. Tools: Read, Grep, Glob, Bash + 5 RAG MCP. Output: concise findings <500 words + file:line refs. Skills: `contract-workflow` + `permission-matrix` + `ef-core-migration`.

## 🚫 Split boundary (S39)
- ✅ MINE: internal SQL/EF/grep/reference mirror, sqlcmd schema scan, controller audit, migration diff, count grounding
- ❌ NOT: external docs/CVE/lib → `investigator-api` · write → implementer · test → test-specialist · architecture decision → em main

---

## 📋 Patterns proven (apply confidently)

### Schema scan via sqlcmd
```bash
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..."     # runtime API (primary)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..."  # ef tooling
ssh vietreport-vps "sqlcmd -S .\SQLEXPRESS -d SolutionErp -U vrapp -P '...' -Q '...'"  # prod
```
Queries: `sys.columns`, `sys.triggers`, `__EFMigrationsHistory`, `COUNT(*)`, `sys.indexes`.
**Gotcha 2 LocalDB distinct** (`feedback_designtime_runtime_db`): `_Dev`=runtime (appsettings.Development), `_Design`=`dotnet ef` default. Prod password fallback `C:\inetpub\solution-erp\api\appsettings.Production.json` khi `$env:PROD_DB_PASSWORD` empty.

### Controller / wire-claim audit
- Grep `\[Route\("api/[a-z]+"\)\]` enumerate controllers · `\[Authorize(Policy = "..."` per-action policy (gotcha #44 silent 403 class-level quá strict)
- Grep `// Mock` / `alert(` / `setEditing(null) // close UI` — wire claim bugs · `IActionResult` vs `ActionResult<T>`

### Smoke verify catalog
Bearer từ `POST api.solutions.com.vn/api/auth/login` → status matrix expected vs actual + file:line evidence.

### Memory cross-reference
27 user-memory tại `C:\Users\pqhuy\.claude\projects\D--...\memory\MEMORY.md` (index). Key: per_chunk_commit · uat_skip_verify · audit_reuse_before_clone · designtime_runtime_db · per_nv_permission_scope · ef_migration_backfill_reorder · status_handoff_tiering (S40) · 7agent_split_upgrade (S39).

### External research → DEFER `investigator-api` (split S39)

## ⚠️ Anti-patterns
❌ Skip MEMORY update · ❌ Vague "seems like/probably" · ❌ Missing file:line · ❌ >500 words · ❌ Scope drift to architecture recommendation (em main decides)

## 🧠 SOLUTION_ERP context essentials (S40 verified — re-grounded)

- **DB:** Dev `SolutionErp_Dev` · Design `SolutionErp_Design` (distinct) · Prod `.\SQLEXPRESS`/`SolutionErp`/`vrapp` via SSH `vietreport-vps`
- **Migration path:** `src/Backend/SolutionErp.Infrastructure/Persistence/Migrations/*.cs` (⚠️ NOT root `/Migrations/`). **40 mig**, last `20260528090839_AddAttendances`.
- **Counts S40:** 40 mig · **84 SQL tables** (77 DbSet + 7 Identity, count `.ToTable()` ModelSnapshot NOT DbSet) · ~211 endpoints · 65 FE pages (36 admin + 29 user `*Page.tsx`) · ~53 menu keys (BE `MenuKeys` const) · **130 test** (58 Domain + 72 Infra) · **55 gotchas** (format `### N.` highest #55) · 27 user-memory · 6 skills · 7 sub-agents
- **Tech:** .NET 10 Clean Arch (Api→Application←Domain + Infra) + CQRS MediatR + EF Core 10 + 2 React 19 Vite 8 TS 6 (fe-admin :8082 + fe-user :8080) + SQL Server + Gitea CI + IIS
- **Prod:** api/admin/eoffice.solutions.com.vn · Gitea `git.baocaogiaoduc.vn/vietreport-admin/solution-erp` (Actions API `/api/v1/repos/.../actions/tasks` NOT `/runs` 404, cache stale ~2min gotcha #46 — cross-check VPS mtime)
- **Auth:** `admin@solutions.com.vn/Admin@123456` (full) / `nv.test@solutions.com.vn/TestUser@123456` (Drafter). Response `accessToken`+`refreshToken`+`user`. Password ≥12 chars.

## 🔄 Active workflow schemas (V1 + V2 coexist post-S17)

- **V1 Mig 21 flat** — `WorkflowDefinition` pin PE/Contract cũ. Match Dept+PositionLevel.
- **V2 Mig 22-31** — `ApprovalWorkflow` pin PE/Contract mới, match `ApproverUserId` 1-1 OR-of-N cùng Cấp. Steps (Phòng) > Levels (Cấp). PE + Contract đã wire V2 (Mig 32+33 S29). Proposal V2 (Mig 38 S37 inline ApproveV2Async). WorkflowApps skeleton (Mig 39 S38 — ApproveV2 advance DEFER Phase 11).
  - Mig 25 IsUserSelectable · Mig 26 PE LevelOpinions UPSERT · Mig 29 Allow* per-NV (F1/F3 per Approver slot + F2 `Users.AllowDrafterSkipToFinal`) · Mig 30 F4 AllowApproverEditBudget · Mig 31 SkipToFinal→ApproverLevel
- **State machine PE 5 trạng thái:** Nháp / Đã gửi duyệt / **Trả lại (TraLai=98)** / Từ chối / Đã duyệt
- **Mode Trả lại 4 option per-Level:** OneLevel (lùi 1 Cấp) / OneStep (lùi Bước trước) / Assignee (pick NV đã ký) / Drafter (Phase=TraLai). 3 mode đầu giữ ChoDuyet lùi pointer. Admin bypass `level.Allow*`.

Create cmd `PurchaseEvaluationFeatures.cs:19-30`; MaPhieu gen-AT-CREATE `:114-116` format `PE/{YYYY}/{A|B}/{Seq:D3}` (`PurchaseEvaluationCodeGenerator.cs:23`). Main create UI = `PeWorkspaceCreateView.tsx` (:151 workflow-select isUserSelectable ĐẦU TIÊN → tenGoiThau → projectId → DiaDiem → MoTa → PaymentTerms → budget; canSubmit :129 = wf+project+ten). PE controller class-`[Authorize]` ONLY no policy → mở menu là đủ, no silent-403. Pe_* leaves NOT in `MenuKeys.All` (chỉ root :156); PE defaults 7 role × 11 key (root + 2type×{group,WfView,List,Create,Pending}) `DbInitializer.cs:2098-2160`. S57 `SeedAllRolesReviewReadPermissionsAsync:1993-2001` InReviewScope EXCLUDES Pe; extend đúng = `key == MenuKeys.PurchaseEvaluations` EXACT (prefix "Pe" sẽ dính PeWorkflows admin!) — root inherit cascade (`GetMyMenuTreeQuery.cs:49-82`). Demo gate: prod `appsettings.json:35 DemoSeed:Disabled=true` → 7 `[DEMO]` HĐ + 4 `[DEMO]` PE (MaPhieu `[DEMO]-A-001`) KHÔNG lên prod; UNGATED trên prod = 31 users + 18 demo NCC + 8 demo project (:2244-2315) + real 62/71/3 (:2329-2522). ⚠️ Clear-demo gotcha: seed re-add per-code idempotent MỖI startup → xóa DB-only sẽ resurrect, phải gỡ khỏi DbInitializer code. WorkItem write Admin-only (`CatalogsController:113-130`) — CatalogManager có menu-perm nhưng API write bị chặn. Tag `[s57bis, pe-recon, demo-inventory]`.

- **2026-06-10 (S57 perm-broaden blocks A/B/E/F — on-disk):** ⭐ **BE AUTHZ SPLIT (decision-critical for E):** Config controllers gate WRITE behind `[Authorize(Roles="Admin")]`, READ open to any-authed: `HrmConfigsController.cs:15` class `[Authorize]`+GET open `:19-21`, all POST/PUT/DEL `Roles="Admin"`; `CatalogsController.cs:14` same (write `:23+` Admin); `MeetingRoomsController.cs:15` same (comment `:9-10` explicit). → granting FE read on Hrm_Config/Catalogs/MeetingRooms = pure UI-visibility, BE already correct. **BUT Master 3 controllers = class `[Authorize]` ONLY, no per-action role:** `SuppliersController.cs:17`, `ProjectsController.cs:11`, `DepartmentsController.cs:11` — ANY authed user can POST/PUT/DELETE via API (FE menu perm is only gate, not BE-enforced). Flag em-main: making Suppliers/Projects/Departments visible-to-all ⇒ staff can write master incl. S55 prod data unless add `[Authorize(Roles="Admin,CatalogManager")]` or per-action policy. **S55 PROD DATA location:** `SeedRealMasterDataAsync` `:2267-2460` writes to **Projects**(62, `:2270`), **WorkItems**(71=CatalogWorkItems key, `:2430-2438`), **Suppliers**(3, `:2440-2456`) — all ungated idempotent per-code. **10 departments now** (`SeedDepartmentsAsync:2104`): 9 orig + IT (`:2115`). **31 demo users** (`SeedDemoUsersAsync:1553-1609`): dept spread BOD4/PM2/CCM9/PRO6/QS2/FIN2/ACT1/EQU1/HRA2; roles = mostly Drafter/CostControl/Procurement + 1 CatalogManager (`catalog.manager@`, dept PRO, `:1608`). NO user has zero-role; every demo user authenticatable. **Inherit-root display:** `GetMyMenuTreeQuery.cs:96 HasAccess = CanRead OR Children.Any(HasAccess)` → a non-inherit root (Hrm/Off/Master) auto-shows if ANY child has CanRead, so granting leaves is enough to reveal the root node (root row itself optional for display, but grant it too for cleanliness). Inherit-roots (Contracts/Pe/Wf/PeWf) cascade root→child so root-row-only suffices there. Menu already S57-edited: `Personal` group + `Off_ChamCong` re-parent Off→Personal via `parentBackfill:1908`.

Hrm/Off/Master NOT inherit → each leaf needs own row or add to switch. **GRANT-ALL pattern (block D):** mirror CatalogManager seeder but loop `roleManager.Roles` (all 13) × chosen key-set, CanRead=true only, insertion AFTER SeedCatalogManagerPermissionsAsync `:1976`. Tag `[s57-perm-recon, seed-model, no-employee-default, inherit-4root]`.

BUT Label/ParentKey/Icon NOT touched on existing rows (`:1855` comment) — rename needs separate `labelBackfill` dict `:1874`. **Order = BE-only:** `GetMyMenuTreeQuery.cs:35 OrderBy(m.Order)`; both FE `Layout.tsx` render `useAuth().menu` as-is, `staticMap`+`menuKeys.ts` = key→route ONLY (no sort). FE needs NO edit for pure reorder. **NAMGROUP "Puro" = hardcoded FE array (NOT DB seed),** index=order: client `InternalLayout.tsx:83-118` (Nhân sự 3-item / Văn phòng số 6-item FLAT / Chấm công under separate "Cá nhân" group); admin `AdminLayout.tsx:87-119` splits by function not HR/office.

(c) **EmployeeProfile** (`EmployeeProfileConfiguration.cs:24/26` EmployeeCode+UserId) — Delete soft (`EmployeeFeatures.cs:437`) BUT Create BLOCKS reuse by design: UserId check `AsNoTracking().FirstOrDefault(UserId==)` (no HRM global filter) sees soft-deleted → throws ConflictException "Cần khôi phục" :160-163; EmployeeCode auto-gen atomic (never user-supplied/reused) → no collision. **Completeness (grep ALL `.IsUnique()`):** beyond 3 Master + 6 HRM-fixed (LeaveType/Holiday/Shift/OtPolicy/Vehicle/Driver all `.HasFilter([IsDeleted]=0)`), every OTHER bare-unique is either composite junction (Permission RoleId+MenuKey, *LevelOpinion, MeetingBookingAttendee, LeaveBalance, Attendance UserId+Date), nullable-code already filtered (`[Ma*] IS NOT NULL`: Contract/PE/Proposal/Budget/WorkflowApps), or no-soft-delete (WorkflowDefinition/ApprovalWorkflow Code+Version, ContractTemplate FormCode, WorkflowTypeAssignment, DepartmentApprovals). **Mig 46 = exactly 3 indexes (Departments/Suppliers/Projects Code).** Surprise: Master GLOBAL query filter MAKES the bug (auto-hides soft-deleted from check) — opposite of HRM where bug needs manual `!IsDeleted`; either way unfiltered index = 500.
