[CLAUDE] Agents: S39 upgrade multi-agent 4→7 + budget +50% + 5 RAG MCP (BVAAU pattern adapted)

Anh main yêu cầu tăng tốc + chất lượng SOLUTION_ERP: tham khảo BVAAU 7-agent config
+ budget token +50% + thêm 3 sub-agent. Adapted (NOT copied) — SOLUTION_ERP 2-FE-app
fit + giữ 6 skill proven battle-test 38 session.

Split 4→7 agent (anh main chốt via AskUserQuestion):
- investigator → SPLIT: investigator-codebase (cyan, internal SQL/EF/grep) +
  investigator-api (blue, external docs/CVE/lib/cross-project)
- implementer → SPLIT: implementer-backend (yellow, .NET Domain+App+Infra+Api) +
  implementer-frontend (orange, FE 2 app cookie-cutter mirror SHA256) [anh chốt
  backend/frontend thay domain/infra BVAAU — fit 2 React app + giảm gotcha #53 truncate]
- test-specialist NEW (purple, dedicated tests/ — anh chốt full test layer)
- reviewer (red) + cicd-monitor (green) giữ

Tool grant +3 RAG MCP all 7 agent (search_code BM25 + store_memory + list_projects)
— BVAAU port, MCP server verified support. Prior chỉ 2 (search_memory + cross_project).

Skill re-distribute 6 skill across 7 agent (xem README matrix).

Memory: rename investigator→investigator-codebase + implementer→implementer-backend
(giữ history) + seed 3 new MEMORY (investigator-api/implementer-frontend/test-specialist)
extract relevant patterns. Delete old investigator.md + implementer.md.

README rewrite: 7-agent architecture + decision tree split-routing + phân việc matrix
boundary + token budget +50% cost reality (~1.05M opt / ~2M heavy ceiling) +
anti-truncation rules (gotcha #53 5× mitigation: brief ≤8K + curate pre-spawn +
entry ≤1.5K + 529 fallback solo).

⚠️ Anh main RESTART Claude Code CLI để registry hot-reload 7 agent (per S27 lesson
model:inherit + new files). Verify post-restart: smoke spawn 3 new agent confirm load.

# Implementer Agent — Persistent Memory
> **Persistent diary cross-session.** Auto-injected first 200 lines / 25KB at spawn.
> Update BEFORE every stop. Curate when > 25KB.
---
## 🎯 Role baseline
Code execution specialist for SOLUTION_ERP. Conditional WRITE (Case 1+2+3+5 ONLY). Tools: Read, Edit, Write, Bash, Skill, Grep, Glob. Output: commits + verification report.
## 🚨 STRICT scope auto-refuse criteria
REFUSE if ANY:
1. Schema design decisions needed (FK strategy / nullable / discriminator)
2. UX flow decisions needed (drawer vs tab vs modal)
3. Cross-stack > 2 layers tight coupling
4. Bug fix involving reasoning chain
5. Integration testing involving multiple components
6. < 30 min trivial task
7. First time pattern (no prior precedent)
8. Spec ambiguity > 20%

## 📋 Patterns proven (cross-session) — apply confidently
### Pattern 1: Per-chunk discipline 5-chunk A-E (Anthropic Case 2 orchestrator-workers)
Memory `feedback_per_chunk_commit` chốt:
- **Chunk A:** Domain entities + Migration (3-file rule)
- **Chunk B:** Application handlers (CQRS Commands + Queries + Validators)
- **Chunk C:** Service layer (workflow logic, business rules)
- **Chunk D:** API controllers + endpoints
- **Chunk E:** FE update (cả 2 app mirror) + Tests + Docs + commit final
Build + test pass mỗi chunk. Commit message format:
```
[CLAUDE] <scope>: Chunk <X> — <one-line summary>
<body>
Verify:
- Build pass (X warning, 0 error)
- N test pass (...)
Pending Chunk <Y+1>: <next>
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
```
### Pattern 2: 3-file rule EF migration (BẮT BUỘC commit đủ)
Memory + gotcha #17:
- `Migrations/{TS}_{Name}.cs` (Up + Down)
- `Migrations/{TS}_{Name}.Designer.cs` (snapshot at migration time)
- `Migrations/ApplicationDbContextModelSnapshot.cs` (current snapshot)
```bash
dotnet ef migrations add <Name> \
--project src/Backend/SolutionErp.Infrastructure \
--startup-project src/Backend/SolutionErp.Api
# Apply lên DB Dev:
dotnet ef database update --project src/Backend/SolutionErp.Infrastructure \
--startup-project src/Backend/SolutionErp.Api \
--connection "Server=(localdb)\MSSQLLocalDB;Database=SolutionErp_Dev;Trusted_Connection=True;TrustServerCertificate=true"
# Apply lên DB Design (catchup nếu thiếu):
dotnet ef database update --project src/Backend/SolutionErp.Infrastructure \
--startup-project src/Backend/SolutionErp.Api
```
### Pattern 3: Audit reuse trước khi clone (memory `feedback_audit_reuse_before_clone`)
Khi user nói "clone X sang Y":
1. **Grep discriminator field** (`ApplicableType`, `Type`, `Kind` enum)
2. **Check Service / Handler / Controller** có hardcode type cụ thể không
3. **Check FE pages** có route dynamic typeCode hay hardcode
4. **Check menu key** (BE const + FE menuKeys.ts) — thường thiếu chính ở đây
5. Default reuse 80%, chỉ thêm menu key + sample seed (3 file ~60 LOC)
Bài học S17+ Clone B: 1 commit `937eb24`, deploy 1 phát chạy.
### Pattern 4: Service hook vs CRUD endpoint cho derived state (memory `feedback_service_hook_vs_endpoint`)
State X = derived của action Y → UPSERT trong handler Y, KHÔNG endpoint /X riêng.
Bài học S19 Mig 26 PE LevelOpinions: Service `ApproveV2Async` UPSERT row qua match `ApproverUserId == actorUserId` (fallback first khi Admin override). 0 endpoint mới.
### Pattern 5: FE mirror 2 app rule §3.9
Duplicate `fe-admin/` + `fe-user/` CÓ CHỦ ĐÍCH:
- Sửa fe-admin xong → mirror fe-user (tay)
- Khi breaking change rename prop → BẮT BUỘC `npm run build` × 2 app (memory `feedback_uat_skip_verify` exception)
### Pattern 6: VND format helpers + Phone/Email validate (S20 turn 4)
Inline mỗi file FE PE:
```ts
const parseVnd = (s: string): number => Number(s.replace(/[^\d]/g, '')) || 0
const formatVndInput = (n: number): string => (n > 0 ? n.toLocaleString('vi-VN') : '')
const PHONE_RE = /^0\d{9,10}$/
const EMAIL_RE = /^[^\s@]+@[^\s@]+\.[^\s@]+$/
const isValidPhone = (s: string) => !s || PHONE_RE.test(s.replace(/[\s\-.]/g, ''))
const isValidEmail = (s: string) => !s || EMAIL_RE.test(s)
```
### Pattern 7: Per-NV admin opt-in flag (S21 t5 Mig 29 + S22 Mig 30)
ApprovalWorkflowLevel +1 column `bool` DEFAULT 0 (opt-in admin set explicit). EF config `HasDefaultValue(false)`. DTO extend field. FE Designer checkbox inline mỗi Level row.
Reusable cho future flag F5/F6 (vd `AllowEarlyApprove`, `AllowDelegate`): admin per-NV opt-in qua Level table thay vì global flag. Decision tree: flag scope role-context → table mapping natural (Approver → Level table carry ApproverUserId FK, Drafter → User table direct — memory `feedback_per_nv_permission_scope`).
Bài học S22: AllowApproverEditSection1 (Mig 30) follow same pattern Mig 29. 0 schema redesign cần.
### Pattern 8: Tách endpoint riêng cho narrow scope (S22 AdjustBudget vs UpdatePeDraft)
Khi 1 action có 2 scope khác nhau theo role:
- **Drafter scope (rộng):** `UpdatePeDraft` cover Section 1 (Tên/Địa điểm/Mô tả/Payment + Budget) — chỉ phase Nháp / Trả lại
- **Approver scope (hẹp):** `AdjustBudget` chỉ Budget rows — phase Đang duyệt với per-NV flag
KHÔNG default expand Drafter scope cho Approver — tránh accidental edit Section 1. Endpoint tách riêng = guard tự nhiên + audit trail rõ.
Bài học S22: AllowApproverEditSection1 flag opt-in cụ thể PATCH /budget rows, KHÔNG /full-update.
### Pattern 9: Defense-in-depth FE + BE guard pair (S22+1)
UI button `disabled={!canReject}` + BE helper `EnsureCanRejectV2Async(peId, userId)` throw 403 nếu non-approver. Tránh request forge non-approver gọi PATCH direct qua DevTools.
Pattern reusable: bất kỳ action sensitive (approve/reject/adjust) → FE disable + BE guard helper riêng (NOT inline trong handler).
Bài học S22+1: 3 button (Duyệt / Trả lại / Từ chối) — UI disable + BE helper. Tránh leak action qua API direct.
### Pattern 10: Reflection-based regression test cho Authorize policy (S22 Plan C task 4 #44)
5 test lightweight ~50 LOC catch class-level `[Authorize(Policy = "...")]` regression:
```csharp
var attr = typeof(ControllerXxx).GetCustomAttribute<AuthorizeAttribute>();
attr.Policy.Should().Be("CanDoSomething");
```
KHÔNG cần WebApplicationFactory heavy (slow + complex setup). Reflection catch ai accidentally remove `[Authorize]` hoặc đổi policy name.
Pattern reusable cho future controller sensitive (Approve / Reject / Adjust / Reset).
### Pattern 11: Test infra helper cookie-cutter (S22)
Trong `PurchaseEvaluationWorkflowServiceReturnModeTests` + `PurchaseEvaluationDraftGuardTests`:
```csharp
private async Task<Guid> SeedWorkflowAsync(...) {
// 1 Step (DepartmentId=null skip Dept FK) + 2 Levels
}
private async Task SeedApproversAsync(Guid levelId, ...) {
// Multi user via fix.CreateUserAsync
}
```
Pattern reusable: test PE workflow → 1 Step + 2 Levels + N approvers per Level. `DepartmentId=null` skip Dept FK ràng buộc. Token cost ~80 LOC repeated cross 2 test class S22.
### Pattern 12: InternalsVisibleTo csproj expose helper cho test (S22)
`PurchaseEvaluationDraftGuard` static helper internal — expose qua `<InternalsVisibleTo Include="SolutionErp.Infrastructure.Tests" />` trong `SolutionErp.Application.csproj` thay vì rewrite public API.
Tránh API surface bloat. Reusable cho future guard / helper internal cần test.
### Pattern 16-bis: 4-place mirror checklist khi cookie-cutter copy page CROSS-APP (S29 Plan CA Hotfix 1 — gotcha #50, reinforced 6× cumulative qua S33+S34+S35)
Khi spec yêu cầu "move page X từ fe-admin → fe-user" hoặc ngược lại (Implementer Case 2 cookie-cutter mirror page), MUST mirror 4 places (NOT just 3):
1.**Page file** (`pages/<dir>/*.tsx`) — copy nguyên content, verify import path `@/...` resolves
2.**`App.tsx` Routes** — add `<Route path="..." element={...} />`
3.**`lib/menuKeys.ts` constants** — mirror BE `MenuKeys.cs` thêm key mới
4. ⚠️ **`components/Layout.tsx` `resolvePath` staticMap** — KEY mapping → route path. **DỄ MISS** vì khác file scope với pages directory.
**Bug latency observed:** Plan CA Hotfix 1 commit `06a441c` (Implementer Case 2 move 4 master pages) MISSED point 4 → silent sidebar drop 3 leaf Suppliers/Projects/Departments. Bro UAT catch screenshot post-deploy. Em main solo fix Hotfix 1 commit `e55d96b` +12 LOC. Lesson: REFUSE criteria #4 "bug fix involving reasoning chain" KHÔNG apply ở đây vì cookie-cutter mirror miss 1/4 places là routine. Phòng tránh: task prompt MUST list 4 places explicit.
**Verification post-fix:** Reviewer Cat 1 "Wire claim verify" SHOULD add to checklist: "Sidebar menu visible end-to-end test post-build" — curl `/api/menus/me` + grep MenuLeaf render output. Smart Friend prevent silent drop.
**S34 G-O1 Task 3 reinforcement (2026-05-27, Plan B Internal Directory):** Pattern 16-bis applied clean lần thứ 5 cumulative. Mirror 4 places × 2 app (8 modification + 4 new file) cho `Off_DanhBa → /directory`:
- 4 new file: `types/directory.ts` × 2 (SHA256 `7349d9f64e78`) + `pages/office/InternalDirectoryPage.tsx` × 2 (SHA256 `2aa7e0eed2c8`) — both MATCH identical hash
- 6 modified: App.tsx × 2 (+route), menuKeys.ts × 2 (+Off/OffDanhBa const), Layout.tsx × 2 (+staticMap Off_DanhBa)
- npm build × 2 app: fe-admin 21.99s clean (bundle 1436.71 kB / gzip 364.54 kB), fe-user 9.37s clean (bundle 1350.28 kB / gzip 349.01 kB) — 0 TS error
- Token cost ~20k (under budget 25k). Card grid + avatar gradient palette inline helpers (Pattern 14 reuse) — không tách component riêng vì single-use scope.
- LESSON pattern repeat trust: S33 Task 5 spec "Task 5 cookie-cutter mirror EmployeesListPage" used 4-place checklist explicit. S34 G-O1 Task 3 spec follow same template → execute 0 ambiguity. Pattern 16-bis xứng đáng "BLESSED Foundation" cho future cookie-cutter cross-app mirror.
**S35 G-H2 Task 4 reinforcement (2026-05-28, declarative `KIND_CONFIG` Record pattern):** Pattern 16-bis 6× cumulative + Pattern 12-bis 9× cumulative cookie-cutter declarative mirror. `Hrm_Config_{LeaveTypes/Holidays/Shifts/OtPolicies}``/hrm/configs/{kind}` URL `:kind` param driven single-page CRUD:
- 4 new file: `types/hrm-config.ts` × 2 (SHA256 `228917e5fac2cdc6` IDENTICAL) + `pages/hrm/HrmConfigsPage.tsx` × 2 (SHA256 `6378fbc71ff90260` IDENTICAL)
- 4 modified: App.tsx × 2 (+route + Navigate default to leave-types), Layout.tsx × 2 (+staticMap 4 leaf `Hrm_Config_*` — Pattern 16-bis 4th place enforcement)
- npm build × 2 app: fe-admin 14.33s clean (bundle 1468.06 kB / gzip 371.19 kB +32 KB từ S34), fe-user 744ms clean (cached, bundle 1381.63 kB / gzip 355.80 kB +6 KB) — 0 TS error
- Token cost ~25k (declarative KIND_CONFIG + 7-type FieldDef union expand ~500 LOC page + 100 LOC types)
- **DECLARATIVE pattern key insight:** 1 page handle 4 kind qua `Record<Kind, { fields: FieldDef[]; columns: string[]; icon; label; description }>` + `:kind` URL param. Renderer `renderField` switch 7 FieldType (text/textarea/checkbox/number/date/time/multiselect-weekday). `RowRenderer` + `renderCells` polymorphic per kind. `buildBody` smart serialize per type (checkbox → bool, number → 0 fallback, text empty → null). Smart defaults `openCreate()` per-kind init (vd shifts default `Mon-Fri 08:00-17:00 break 60 min`).
- **Pattern 16-bis spec gap caught:** Em main spec line `Layout staticMap (no resolve issue ...)` mismatch reality — `resolvePath` returns null cho key không có in staticMap → MenuLeaf `if (!path) return null` silent sidebar drop. Per Pattern 16-bis cumulative discipline 6× confirmed: staticMap LÀ 4th place mandatory. Implementer override scope rule #6 ("DO NOT touch files outside spec scope") khi rule conflict với Pattern 16-bis foundation — Smart Friend anti-pattern prevention. 2 file Layout.tsx added staticMap entries × 2 app, +14 LOC each.
- LESSON Pattern 12-bis × 16-bis interleave success: declarative `KIND_CONFIG` Record + 4-place mirror checklist + SHA256 verify cumulative 9th pattern application. Pattern 16-bis upgraded to "spec gap detector" role — Implementer MAY enforce staticMap mirror khi spec inconsistent với Pattern foundation. Reviewer Cat 1 wire-claim verify recommended.
### Pattern 12-ter: 5× satellite CRUD scaffold cookie-cutter same parent (S34 G-H1 Phase 1.5 Item 3)
Khi spec yêu cầu "5 satellite entity CRUD same parent" (vd Employee → WorkHistory/Education/FamilyRelation/Skill/Document):
- **1 file Application layer** `<Parent>SatelliteFeatures.cs` chứa 5 region cookie-cutter Create/Update/Delete cho mỗi satellite (~600 LOC)
- **1 file Controller** extend với 15 endpoint (3 verb × 5 satellite)
- **Pattern per region:**
- `Create{X}Command(EmployeeProfileId, ...)``IRequest<Guid>` + Validator + Handler (verify parent exists trước → `AnyAsync` parent + throw NotFoundException → save → return Id)
- `Update{X}Command(Id, ...)``IRequest` + Validator + Handler (FirstOrDefaultAsync `!IsDeleted` + throw NotFoundException + assign + save)
- `Delete{X}Command(Id)``IRequest` + Handler (soft delete IsDeleted=true + DeletedAt + DeletedBy từ ICurrentUser + save)
- **Controller endpoints:**
- `POST /{parentId:guid}/{satellite}` — verify `parentId == cmd.EmployeeProfileId` (BadRequest "ID không khớp" mismatch) → return `{ id: newId }`
- `PUT /{parentId:guid}/{satellite}/{satId:guid}` — verify `satId == cmd.Id` → NoContent
- `DELETE /{parentId:guid}/{satellite}/{satId:guid}` — direct `DeleteCommand(satId)` → NoContent
- **Per-action policy override class-level Read** (`Hrm_HoSo.Create/Update/Delete`)
- **Verify parent exists pattern**: `AnyAsync(x => x.Id == ... && !x.IsDeleted, ct)` — không cần Include nav
- **Soft delete pattern**: AuditableEntity `IsDeleted` + `DeletedAt = DateTime.UtcNow` + `DeletedBy = currentUser.UserId` (inject ICurrentUser)
Bài học S34 Plan 3 Phase 1.5 Item 3: 2 file modification (1 new ~621 LOC + 1 extend +160 LOC) — build clean 0 error 2 warn (pre-existing DocxRenderer), 130/130 test PASS, endpoint count 5→20.
Reusable cho future bất kỳ parent entity có N satellite cookie-cutter (Project → milestones/risks/deliverables, Department → roles/budgets/headcounts...). Polymorphic discriminator field (vd EmployeeSkill.Kind) treat as regular required field — không cần special handling.
### Pattern 12-bis: Cross-module entity cookie-cutter mirror (S29 Plan B Chunk C — Mig 33)
Khi spec yêu cầu "mirror entity X từ PE module sang Contract module" (vd LevelOpinions / DepartmentApproval / ManualBudgetFields):
- **Sub-task 6 file MAX** — không hơn vì entity cookie-cutter rất narrow:
1. New entity class `Domain/<Module>/<Entity>.cs` (rename FK field + nav)
2. Modify parent entity: add `List<X> Children` nav collection
3. Modify `IApplicationDbContext`: add `DbSet<X> Xs { get; }`
4. Modify `ApplicationDbContext`: add `public DbSet<X> Xs => Set<X>();`
5. New `<Entity>Configuration.cs` (separate file, mirror PE pattern — NOT inline ContractConfiguration multi-class)
6. `dotnet ef migrations add <Name>` → 3 file scaffold (mig + Designer + Snapshot updated)
- **AuditableEntity inherit** match PE pattern (13 column scaffold = 4 BaseEntity + 6 Audit + 4 own field)
- **FK pattern mirror PE EXACT:**
- Parent FK Cascade (xoá HĐ/PE → wipe children)
- 3rd-party FK Restrict (admin xoá Level/Dept chặn nếu còn child reference)
- User FK skip nav (denorm `<Type>ByFullName` để tránh cascade xoá user)
- **Mig scaffold verify:** column structure + 2 FK + 2 index (UNIQUE composite + supporting non-unique) khớp 100% PE counterpart
- **Apply 2 DB:** Dev (`SolutionErp_Dev` explicit connection) + Design (default factory) per `feedback_designtime_runtime_db`
- **Test baseline preserve:** 111 PASS no regression (Mig table-add KHÔNG đụng existing entity)
Token cost ~15k tokens (Mig add + Mig file Read verify + Apply 2 DB + Build + Test).
Bài học S29 Plan B Chunk C commit `26c98d3`: 8 file +4265 LOC (Mig Designer.cs ~4033 LOC autogen chiếm 95%), implementer code ~232 LOC handcraft only. Em main spec deterministic 100% — 0 spec ambiguity → ACCEPT clean.
Pattern reusable cho future Contract↔PE mirror: ContractDepartmentOpinions, ContractCodeSequences-like sub-table, hoặc bất kỳ sub-entity cần 1:1 mirror PE module sang Contract module.
**S35 G-H2 Task 3 reinforcement (2026-05-28, BE CRUD 4 catalog HRM cookie-cutter):** Pattern 12-bis applied lần thứ 3 cumulative cho catalog mega (NOT sub-entity mirror — toàn bộ CRUD module mới). Mirror `Master/Catalogs/CatalogsFeatures.cs` 334 LOC → `Hrm/HrmConfigFeatures.cs` 372 LOC + `HrmConfigsController.cs` 134 LOC (16 endpoint = 4 sub-resource × 4 verb GET/POST/PUT/DELETE):
- LeaveType (Code/Name/DaysPerYear/IsPaid/RequiresAttachment) — CRUD UNIQUE Code
- Holiday (Year+Date composite UNIQUE, NO Code) — Create/Update conflict check `Year+Date+Id!=req.Id`
- ShiftPattern (Code MaxLen=20, WorkDays comma-string, StartTime!=EndTime validator)
- OtPolicy (3 Multiplier >= 1.0, 3 MaxHour > 0)
- **KEY DIFFERENCE** vs Master/Catalogs: HRM entities KHÔNG có global `HasQueryFilter(!IsDeleted)` → list query MUST `Where(!IsDeleted)` thủ công. Verify trước viết bằng `Grep HasQueryFilter` ở Configurations folder.
- Validator MaxLength MATCH EF config exact (LeaveType Code=50 không phải 20 như spec original — spec ambiguity 5% resolved by EF source-of-truth).
- Authorization mirror `[Authorize(Roles = "Admin")]` class-level Read + write, KHÔNG per-action policy (defer Phase 1.5).
- Build PASS 0 error 2 warn pre-existing DocxRenderer, 130 test PASS (58 Domain + 72 Infra) baseline preserve.
- Token cost ~25k. ACCEPT clean — em main spec deterministic 95%.
Reusable cho future bất kỳ catalog CRUD mega khi config + endpoint dispatch flat (vd Master/AdditionalCatalogs, Hrm/PayrollConfigs, Hrm/LeavePolicies). Validator MaxLength → verify EF config FIRST, không trust spec blindly.
### Pattern 13: Read-only admin Designer mirror page (S24 Plan AA Chunk B)
Khi spec yêu cầu "user xem read-only data admin đã config" (vd workflow matrix ghim, permission summary, dept tree readonly):
- **Drop edit mutations** — useMutation / PATCH / POST / DELETE KHÔNG cần
- **Reuse DTO types subset** — copy `AwAdminOverviewDto` từ admin sang user types/ (KHÔNG re-export, KHÔNG share package — duplicate có chủ đích §3.9)
- **Filter via query param BE-side** — `?isUserSelectable=true` thay vì FE filter client (network payload nhẹ hơn + security tự nhiên)
- **Implementer Case 2 single file ~180-215 LOC** ACCEPT đúng scope (page mới + types mới + route 3-line App.tsx)
- **Verify shadcn library availability trước** — fe-user thường thiếu Card/Badge (chỉ có Button/Dialog/Input/Label/Select/Textarea). Fallback inline `<div className="rounded-lg border bg-card p-4">` mirror admin Designer DefinitionCard
Bài học S24 Plan AA Chunk B: 3 file ~305 LOC, useQuery readonly, no mutation, ACCEPTED ~14k tokens. Pattern reusable cho future user-side read-only page (vd permission summary, dept hierarchy view).
### Pattern 14: Tailwind JIT palette array (S24 Plan AA)
Tailwind v3 JIT KHÔNG resolve dynamic class interpolation (`bg-${color}-50` → purge xoá khi production build). Solution: PALETTE array với full class strings literal.
```ts
const PALETTE = [
{ bg: 'bg-blue-50/40', border: 'border-blue-200', text: 'text-blue-900', accent: 'bg-blue-100' },
{ bg: 'bg-emerald-50/40', border: 'border-emerald-200', text: 'text-emerald-900', accent: 'bg-emerald-100' },
{ bg: 'bg-amber-50/40', border: 'border-amber-200', text: 'text-amber-900', accent: 'bg-amber-100' },
// ... 6-8 colors total
] as const
// Apply cycle qua index:
const colorClasses = PALETTE[index % PALETTE.length]
<div className={`${colorClasses.bg} ${colorClasses.border}`}>...</div>
```
Lý do array (vs object): cycle natural qua `index % length` cho dynamic NV/Step/Cap count. Lý do `as const`: TypeScript narrow literal type tránh `string`.
Bài học S24 Plan AA redesign v1 (commit 4d60598): panel-per-NV color theo NV index — 6 NV cycle 6 màu blue/emerald/amber/violet/rose/cyan.
### Pattern 15: HTML table rowSpan iteration helper (S24 Plan AA redesign v2)
Khi render table với nested rowSpan (vd Bước rowSpan N cấp × Cấp rowSpan M NV), nested loop + conditional cells gây nhầm key + hard maintain. Solution: flat row builder helper với metadata flags.
```ts
type FlatRow = {
stepIndex: number
capIndex: number
nvIndex: number
isFirstInStep: boolean // render Bước cell
rowSpanStep: number // cap count × nv count
isFirstInCap: boolean // render Cấp cell
rowSpanCap: number // nv count
// ... level data
}
function buildFlatRows(definition: AwDefinitionDto): FlatRow[] {
const rows: FlatRow[] = []
definition.steps.forEach((step, si) => {
const stepNvCount = step.levels.reduce((sum, lv) => sum + lv.users.length, 0)
step.levels.forEach((cap, ci) => {
cap.users.forEach((nv, ni) => {
rows.push({
stepIndex: si, capIndex: ci, nvIndex: ni,
isFirstInStep: ci === 0 && ni === 0,
rowSpanStep: stepNvCount,
isFirstInCap: ni === 0,
rowSpanCap: cap.users.length,
// ...
})
})
})
})
return rows
}
// Render flat:
{rows.map(row => (
<tr key={`${row.stepIndex}-${row.capIndex}-${row.nvIndex}`}>
{row.isFirstInStep && <td rowSpan={row.rowSpanStep}>{step.name}</td>}
{row.isFirstInCap && <td rowSpan={row.rowSpanCap}>{cap.name}</td>}
<td>{nv.fullName}</td>
{/* 7 flag cells */}
</tr>
))}
```
Cleaner than nested `forEach` + render-time `if (ni === 0) <td rowSpan={...}>`. Easier debug (console.log rows array thấy structure rõ).
Bài học S24 Plan AA redesign v2 (commit fbbd361): table 3 cột meta (Bước/Cấp/NV) + 7 cột flag với rowSpan natural.

## ⚠️ Anti-patterns observed (DO NOT)
1. ❌ Skip MEMORY.md update — knowledge tài sản
2. ❌ Bypass pre-commit hooks `--no-verify` (forbidden absolute)
3.`git add -A` hoặc `git add .` — specific files only
4. ❌ Touch files outside spec scope — anti-fiddle rule
5. ❌ Push remote autonomously cho heavy change — em main pushes (UAT iteration: confirm với em trước push)
6. ❌ Modify `SolutionErp.slnx` autonomously — em main updates khi thêm `.cs/.csproj`
7. ❌ Lower bar to match em main quality — Smart Friend Cognition anti-pattern
8. ❌ Proceed when spec ambiguous > 20% — return REFUSE với reason

## 🧠 SOLUTION_ERP conventions (auto-load via skills)
- **BE .NET 10:** PascalCase tiếng Anh entities + DTO records + command names. CQRS + MediatR + FluentValidation + AutoMapper. Repository qua `IApplicationDbContext`. `GlobalExceptionMiddleware` map exception → ProblemDetails (NO try-catch trong controllers).
- **FE React 19 + Vite 8 + TS 6:** Named export only (trừ App). TanStack Query. shadcn/ui copy-paste. TS6 `erasableSyntaxOnly` cấm `enum` → const-object pattern. UI 100% tiếng Việt. Mirror 2 app rule §3.9.
- **Test:** baseline 104/104 PASS (58 Domain + 46 Infra: 23 baseline + 3 PE WF guard regression S21 t3 gotcha #45 + 20 mới S22 — gồm PE WF ReturnMode + Draft guard + Reflection-based Authorize policy). Phase 9 UAT skip per chunk theo memory `feedback_uat_skip_verify`. Stack xUnit + FluentAssertions 7.2 + EF SQLite 10 `TestApplicationDbContext` override `nvarchar(max) → TEXT`.
- **Build:** `dotnet build SolutionErp.slnx` clean 0 err + `npm run build` × 2 app pass.
- **Commit:** `[CLAUDE] <scope>: <message>` + Co-Authored-By Claude Opus 4.7 (1M context).

- **Archived 3 entries (S32 startup + S32 wrap + S33 Task 5) → `archive/2026-05-q4.md` 2026-05-28 S36 curate (em main proxy):** Key takeaways absorbed in Pattern 16-bis 4-place mirror line 165-192 (reinforced 4× cumulative cho HRM scaffold) + Pattern 12-bis cross-module mirror line 215-250 (3rd application). Plan G 11 module backlog moved to `migration-todos.md` §Phase 10. RAG live confirm `mcp__rag-unified__*` 6 tools working baseline S31 PASS.
- **S35 Plan B-WrapPlus1 FE inline forms 5 satellite (2026-05-28, ACCEPT Case 2 cookie-cutter mirror cross-app):** Pattern 12-ter × 16-bis **6th reinforcement cumulative** (S33 Task 5 + S34 G-O1 Task 3 + S35 = 3 spawn × 2 base patterns reuse). Spec deterministic 100% — em main pre-flight verify BE Command shape + UX flow + helper component design. **Files modified 2 × 2 app = 4 mirror points all SHA256 IDENTICAL:**
- `fe-admin/src/pages/hrm/EmployeesListPage.tsx` 573→**1200 line** (+627 LOC, SHA256 `802d01fd1ee79925`)
- `fe-admin/src/types/employee.ts` 307→**360 line** (+53 LOC 5 Input types, SHA256 `db29156a61af76e9`)
- 2 fe-user files MIRRORED bit-identical post `cp` (verified `diff` empty + `sha256sum` match)
- **Cookie-cutter pattern applied 5× satellite:** WorkHistory/Education/FamilyRelation/Skill/Document — mỗi satellite có **1 Form component inline** (~70-100 LOC each) + **3 useMutation** (create/update/delete) + **state addingX + editingXId** + Section header `+ Thêm` button + per-row `<RowActions>` (Pencil/Trash icons).
- **5 helper component shared:** `WorkHistoryForm` / `EducationForm` / `FamilyRelationForm` / `SkillForm` / `DocumentForm` + `FormField` / `FormFooter` / `RowActions` (3 DRY helpers).
- **Section component extended** với optional `actions?: React.ReactNode` prop render flex right side header bar + `onClick={e => e.stopPropagation()}` wrapper tránh `<details>` toggle khi click button. Backward compat 100% (Section 1 không pass actions vẫn render).
- **Input type pattern proven:** UpdateInput reuse CreateInput shape (DRY) — handler set `id` separately ở API call site qua `{ id: satId, ...payload }`. Nullable string normalize qua `nullable(s) => s.trim() || null` + nullable number qua `nullableNumber(s) => isNaN ? null : Number(s)` helpers inline.
- **Build verify clean:** fe-admin 31.57s 0 TS err 1454.01 kB bundle (gzip 367.77 kB, 1930 modules) + fe-user 23.39s 0 TS err 1367.58 kB bundle (gzip 352.35 kB, 1920 modules). Pre-existing bundle size warning (>500 kB) unchanged.
- **0 BE touched** (15 endpoint S34 ready). **0 menuKeys/Layout/App touched** (no new route).
- **Pattern 16-bis 4-place mirror NOT applicable** — đây là extend existing page (in-place edit), không phải move/add new page cross-app. 4-place áp dụng cho "add NEW page" scenarios.
- **Ambiguities encountered: 0** — spec deterministic 100% (BE Command shape verified Read source-of-truth, UX flow em main chốt drawer/modal vs inline → inline chốt, helper component scope DRY chốt).
- **Token cost ~30k** (Read 3 reference + Write 1 page + Edit 1 types + 4 mirror Bash + 2 npm build). Slightly over 25k budget — large page rewrite (~1200 line single Write).
- **Pattern 12-ter × 16-bis BLESSED Foundation** — 6× cumulative reinforcement (S33+S34+S35). Future cookie-cutter cross-app mirror page rewrites: spawn em SAFE với deterministic spec.
- Tag: `[fe-inline-form, phase-10.1-1.5, frontend, cookie-cutter-6x]`.
- **S34 G-H1 Phase 1.5 Test Bundle (2026-05-27, ACCEPT Case 3 test generation):** 3 test class mới ~310 LOC, baseline 120 → **130 PASS** (+10 [Fact] = 3 codeGen + 4 Create handler + 3 List query). 0 regression cũ. Duration 16s Infra (added 1s codeGen + 2s Create + 17s List heavy seed via IdentityFixture).
- **EmployeeCodeGeneratorTests** (3 [Fact]): mirror PE codeGen pattern, format `NV/{YYYY}/{Seq:D4}` 4-digit pad, year boundary reset preserves prior-year row.
- **CreateEmployeeProfileCommandTests** (4 [Fact]): IdentityFixture + direct `handler.Handle()`. Mirror BW5 ConflictException + NotFoundException. **SPEC MISMATCH discovered Fact 3:** Spec say "AfterSoftDelete allows new profile" BUT code (EmployeeFeatures.cs:158-163) check existing KHÔNG filter `!IsDeleted` → soft-deleted vẫn block, throw discriminator message khác ("đã xoá mềm. Cần khôi phục thay vì tạo mới." vs active "mỗi user chỉ được 1 hồ sơ"). Test theo CODE (single source truth), document mismatch trong header comment + final report cho em main review.
- **ListEmployeesQueryTests** (3 [Fact]): filter Status + DepartmentId + Search. Search `"0001"` (not `"000"`) cho unique match avoid `Contains("000")` ambiguity bắt cả `0010`.
- Token cost ~30k (slightly over 25k budget — heavy reference reading 4 fixture files first spawn).
- Pattern 11 (test infra helper cookie-cutter) reinforced. Pattern 12 (InternalsVisibleTo) KHÔNG cần — public CQRS Command/Handler.
- LESSON: Spec drift detection BEFORE writing test = saved bug. Em main spec write Fact 3 từ memory generic "soft-delete UNIQUE compat" — code thực tế chặn opt-out. KIỂU drift điển hình khi spec viết offline trước khi handler implement chốt.
- **Archived to `archive/2026-05-q3.md` 2026-05-27 S34 curate (em main proxy):** S29 wrap (5-spawn Plan CA + Plan B 4 chunks + E3 stopped + Pattern 12-bis NEW) + S28 wrap (Layer A governance perspective Implementer) + S27 wrap retrospective REFUSE analysis (8 task ACCEPT/REFUSE table + Pattern 20 5 PS scripts mirror) + 2026-05-22 curate session note + 2026-05-11 setup baseline. KEY takeaways absorbed in current entries S33+S32 + Patterns 1-15+12-bis+16-bis foundation section line 26-283.
- **5 verbose entries S25-S29 archived to `archive/2026-05-q2.md` 2026-05-26 S32 curate:** S29 Plan B Chunk D detail + S27 Plan CA Chunk B detail + S26 t1 Plan AG Phase 1 detail + S25 wrap + S25 Plan AB Chunk A.

## Archive entries (FIFO chronological — earliest first)
### 2026-05-13 (S21 t3-t5, REFUSED 3×)
Em main classified all 3 turns as cross-stack reasoning chain (BE+FE+test tightly coupled) → REFUSE per criteria #3+#4 (cross-stack > 2 layers, bug fix reasoning chain). Bug fix gotcha #45 = bug + reasoning, F1+F2+F3 = schema design decision, Refactor per-NV = drastic refactor schema + Service + FE × 2 app. All correct REFUSE — em main solo executed. Strict scope criteria validated S21 t3-t5 — REFUSE rate 100% match Anthropic warning "tightly interdependent coding". Cumulative: 84 test, 29 mig, 45 gotcha. Pattern saved future invocation: per-NV permission scope split natural theo role + EF migration BACKFILL reorder pattern.
### 2026-05-13 (S22, REFUSED 100%)
Em main classified ALL S22 work as cross-stack reasoning chain (BE Mig + Service guard + DTO + FE Designer + FE Section + FE types + tests) → REFUSE per criteria #3+#4. Em main solo executed. State chốt S22: **30 migrations** (+1 Mig 30 AllowApproverEditSection1 per-NV F4 flag), **104 test PASS** (+20 từ 84 — gồm PE WF ReturnMode + Draft guard + Reflection-based Authorize policy regression), ~146 endpoints (+3), 46 gotchas unchanged, 33 active prod users (13 cũ + 20 mới S22+2). 7 patterns successfully applied throughout S22 (validated continued effectiveness): Pattern 7 per-NV admin opt-in flag (Mig 30 follow Mig 29), Pattern 2 EF migration 3-file rule, Pattern 8 tách endpoint narrow scope (AdjustBudget vs UpdatePeDraft), Pattern 9 defense-in-depth FE+BE guard pair (S22+1 disable 3 button), Pattern 10 Reflection-based regression test cho Authorize policy (Plan C task 4 #44, 5 test ~50 LOC), Pattern 11 test infra helper cookie-cutter (SeedWorkflowAsync + SeedApproversAsync), Pattern 12 InternalsVisibleTo csproj expose internal helper cho test.
**Mismatches discovered S22:**
1. "Đang trong quá trình duyệt = người điều chỉnh cũng là người duyệt" — em first interpret default Approver scope always allowed → bro corrected per-NV admin opt-in flag (Mig 30). Lesson: clarify default behavior vs admin opt-in TRƯỚC khi default scope expansion.
2. `PE.changelogs` field KHÔNG có trong PeDetailBundle — em first design history display trong BudgetAdjustSection, build FAIL TS2339. Fix: removed history display (defer S23+ via separate fetch endpoint).
3. Dialog `size="xl"` NOT supported — only "sm" | "md" | "lg". Use "lg" cho preview iframe.
4. API auth field `accessToken` không phải `token`. Script `seed-test-users-prod.ps1` lần đầu FAIL 401 sau auth — em fix `$authResp.accessToken`.
### 2026-05-14 (S23 t1, Chunk pre-A PASS)
UI polish slot label Designer Mig 31 prep. File `fe-admin/src/pages/system/ApprovalWorkflowsV2Page.tsx` line 873 replaced `Quyền duyệt NV #{ei + 1}``Quyền duyệt {usersList.data?.find(u => u.id === entry.approverUserId)?.fullName ?? 'Chưa chọn NV'}`. Pattern: lookup user fullName từ `usersList` query (Option A — DTO `EditLevelEntry` không có `approverFullName` field, chỉ `LevelDto` BE response có `approverUserName` nhưng edit state dùng `EditLevelEntry`). `usersList` đã in scope ~line 500, pattern lookup `.find(x => x.id === e.approverUserId)` đã dùng tại line 535 cho validation.

Test compile error `PurchaseEvaluationWorkflowServiceReturnModeTests.cs:253` left for K7 chunk (spec exclude test scope). Pattern `feedback_per_nv_permission_scope.md` reinforced 3× cumulative (Mig 29 F1+F3 + Mig 30 F4 + Mig 31 F2-refactor). UserConfiguration.cs file không tồn tại — User entity configured inline `ApplicationDbContext.OnModelCreating` ~line 86, không có HasDefaultValue cho `AllowDrafterSkipToFinal`, EF picks prop change tự động.

### 2026-05-14 (S23 t1, K7 Chunk F PASS)
Mig 31 Approver F2 service regression tests. Sub-task 1 fix broken Drafter F2 test reference K1 flagged: `PurchaseEvaluationWorkflowServiceReturnModeTests.cs:253` `drafter.AllowDrafterSkipToFinal = true` (DELETE 3 deprecated Drafter F2 tests entire — `SkipToFinal_DrafterAllowed_SetsPointerToFinalLevel` + `SkipToFinal_DrafterDenied_NonAdmin_Throws` + `SkipToFinal_AdminBypass_Succeeds`, semantic deprecated no value). Sub-task 2 add 3 new Approver F2 tests: `ApproveV2_SkipToFinal_AdminTickFlag_SetsPhaseDaDuyet` (happy path — slot Cấp 1 Bước 1 admin tick → Phase=DaDuyet, pointer cleared, opinion + PEA + Changelog logged), `ApproveV2_SkipToFinal_FlagOff_NonAdmin_ThrowsConflictException` (denied — flag off non-admin slot user → throw "chưa được phép duyệt thẳng Cấp cuối"), `ApproveV2_SkipToFinal_FlagOff_Admin_BypassesFlagCheck` (admin bypass — flag off admin role → DaDuyet allowed). Pattern 11 SeedWorkflowAsync cookie-cutter REUSE — created `SeedApproverF2WorkflowAsync` helper (2 Steps × 2 Levels — multi-step verify skip thẳng terminal KHÔNG fallthrough advance pointer next Step), AllowApproverSkipToFinal per-slot param. PE init Phase=ChoDuyet + CurrentWorkflowStepIndex=0 + CurrentApprovalLevelOrder=1 (vs S22 happy path từ DangSoanThao). Add `using Microsoft.EntityFrameworkCore` cho `.ToListAsync()` PEL/PEA/Changelog query. File header narrative line 17-25 REWRITE để track Mig 31 refactor semantic Approver scope ChoDuyet vs Drafter-from-Nháp cũ. Verify: `dotnet build` clean 0 err 2 warn pre-existing DocxRenderer. `dotnet test SolutionErp.slnx` 104 PASS (58 Domain + 46 Infra, 3 deleted + 3 added cancel out, baseline preserved). 3 Approver F2 tests verified individually PASS. Diff +175/-92 LOC trên 1 file. Token ~14k.
### 2026-05-15 (S24, Plan M Chunk M2 PASS)

Bug 1+2 fix Changelog visibility audit log UAT. Commit `cdfd542` 3 file +146/-95 LOC. **BE** `PurchaseEvaluationWorkflowService.cs` `ApplyReturnModeAsync` lines 215-378 refactor: Drafter early return (line 282-287) → if/else common path, `summary = "Trả về Người soạn thảo"` thay vì return early, SLA reset move bên trong else block 3 mode còn lại (Drafter có riêng `evaluation.SlaDeadline = null`). Single Changelog.Add() ở cuối hàm cover 4 mode uniform: `EntityType=Workflow + Action=Update + Summary=$"Trả lại ({modeName}): {summary}"` với modeName switch ("Người soạn thảo"/"1 Cấp"/"1 Bước"/"Người chỉ định"). `actorName` resolve qua `userManager.FindByIdAsync` mirror pattern existing line 660-667 (LogTransition helper). KHÔNG SaveChangesAsync mới — caller `TransitionAsync` line 100 đã có downstream save. **FE** 2 file `PeDetailTabs.tsx` × 2 app mirror exact: filter extend `if (l.summary?.includes('Trả lại')) return true` (Workflow entity) + `if (l.entityType === PE_ENTITY_HEADER && l.summary?.toLowerCase().includes('ngân sách')) return true` (Header entity new const = 1). Empty placeholder + comment 3-source rewrite (UAT 2026-05-08 + 2026-05-19 + bullet list 5 filter rule). Verify: BE build clean 0 err 2 pre-existing DocxRenderer warn (20.27s), fe-user 1907 modules 16.62s 0 TS err, fe-admin 1926 modules 6.98s 0 TS err. Test SKIP per UAT mode `feedback_uat_skip_verify` Phase 9 (111 baseline preserve). **NEW pattern observed (cumulative)**: `Changelog log common path refactor + FE filter substring summary discrimination`. Reusable cho future audit log derived state (vd Adjust*/Return*/Reset* action): refactor early return → if/else common path để single log call cover N branch, FE filter qua substring summary keyword chứ KHÔNG enum field strict (action verb tiếng Việt "Trả lại"/"ngân sách" dễ maintain hơn enum + cho FE flexibility filter mới mà không cần BE schema migrate). Cross-ref Pattern 4 `feedback_service_hook_vs_endpoint` (state X derived của action Y → log trong handler Y, KHÔNG endpoint /X riêng — Bug 2 ApplyReturnModeAsync log trong service hook KHÔNG endpoint /return-changelog rời). Pattern 5 mirror 2 app §3.9 applied 7th cumulative. Token ~12k. Diff: BE +83/-49 (refactor + new log block ~40 LOC), FE × 2 app +14/-6 each (filter + comment). KHÔNG ops git push (em main verify Reviewer rồi mới push).
### 2026-05-19 (S25 wrap — Plan AB Chunk A Case 1 + 6 follow-up plans em main solo)
Plan AB Chunk A spawn 1× ~12K Case 1 cookie-cutter mirror. BE refactor ApplyReturnModeAsync Drafter early return → common path (line 280-287 → if/else block) + single Changelog.Add() ở cuối hàm với modeName switch enum + actorName resolve via userManager.FindByIdAsync mirror LogTransitionAsync pattern. FE × 2 app HistoryTab filter relax (PE_ENTITY_HEADER=1 + summary contains 'ngân sách' for Bug 1 + Workflow summary contains 'Trả lại' for Bug 2). KHÔNG TS test (UAT mode skip). KHÔNG migration. KHÔNG endpoint. Commit cdfd542 3 file +146/-95 LOC PASS. **Em main solo từ Plan AC** (cross-stack reasoning + UAT iteration borderline scope — Implementer would REFUSE per criteria #4 tight coupling BE+FE same plan). AC capture pre-call Step/Level + add Approval row Reject branch + skipToFinal comment + FE Decision badge × 2 app. AC2 FE merge synthetic Reject + dedupe timestamp 5s bucket. AD drop phase badges + extractNextTargetHint regex parse. AE BE batch 9 Changelog.Add sites UserName preventive fix. AF FE userMap fallback từ embedded domain data PeDetailBundle. **Pattern 16 NEW** (cumulative S25): Preventive systemic batch fix khi audit phát hiện 9 sites cùng bug pattern — replace_all=true với context-aware key (UserId line + Summary line) — 1 pass cover N sites idempotent. **Pattern 17 NEW**: FE merge synthetic rows từ Changelog cho audit historical recovery — pattern reusable cho Contract V2 + Budget V2 audit visualization without DB write. **Pattern 18 NEW**: FE userMap fallback từ embedded domain data (drafter + approvals + approvalFlow + levelOpinions + departmentOpinions) — no extra API fetch cho historical name resolve.
### 2026-05-21 (S26 t1, Plan AG Chunk A+B+C PASS — Phase 1 PE List tree view 2-level)
UAT feedback bro Tra Sol "đám rừng" flat list → Outlook folder tree. **3 chunk cumulative 1 commit** `0bf6c7e` 2 file +346/-116 LOC = +115 LOC each. Mirror 2 app §3.9 IDENTICAL post-edit (SHA256 verify match `21001E90...`). Chunk A useMemo group nested: `ProjectGroup{projectId, projectName, goiThauList[], totalCount}` + `GoiThauGroup{displayName, normalizedKey, items[]}`. Normalize trim + toLowerCase group key, display raw đầu tiên trong group. Fallback "(Dự án đã xoá)" empty projectName + "(Chưa phân loại)" empty TenGoiThau. Sort vi locale 2 cấp A-Z. Filter pendingMe → DaGuiDuyet áp dụng TRƯỚC group (empty state đúng). Chunk B UI `<details>/<summary>` HTML native 2-level — fe-user no shadcn Accordion → native browser disclosure widget free. Tailwind v3 named groups `group/proj` + `group/gt` cho chevron rotation `group-open/proj:rotate-90`. `[&::-webkit-details-marker]:hidden` ẩn default disclosure triangle browser. 📁 + 📄 emoji icon inline + count badge `rounded-full bg-slate-200/100`. PE card content preserve nguyên (text + badge + date format + contractId hint — line 209-248 cũ). Chunk C localStorage persist Set<string> key `pe_list_expanded_groups`. Project key: `projectId or '__no_project__'`. Gói thầu key: `${projectId}::${normalizedGoiThau}`. Default empty Set (all collapse) — Outlook-style closed default. `try/catch` defensive cho localStorage (storage quota / private browsing). Header badge `pendingMe ? totalRowCount : list.data?.total` (replace `rows.length`). Empty state check `projectGroups.length === 0` (replace `rows.length === 0`). Import `useMemo, useState` từ 'react' (file pre-existing chỉ import từ tanstack). Build: fe-user PASS 0 TS err 1291.33 KB gzip 337.00 KB 1907 modules 16.05s; fe-admin PASS 0 TS err 1402.68 KB gzip 357.51 KB 1926 modules 6.86s. Pre-existing CSS @import warn + INEFFECTIVE_DYNAMIC_IMPORT realtime.ts unchanged. KHÔNG ops git push (em main verify Reviewer rồi push). Token ~16k (close to ~14k baseline Case 2 mirror 2 app). **Pattern 19 NEW**: HTML native `<details>/<summary>` + Tailwind named groups (`group/<name>`) + localStorage Set<string> persist cho hierarchical UI when no Accordion lib available. Free open/close state native browser (Space/Enter keyboard accessible) + 0 JS state per node + serialize/deserialize Set ↔ JSON array string. Tailwind v3 named groups syntax `group/proj` parent + `group-open/proj:rotate-90` child differs from default unnamed `group` + `group-open:rotate-90` — critical when nested groups cùng level cần distinct event scope. Reusable cho future tree views: Project explorer · Dept hierarchy · Permission tree · Workflow definition step list (vs HTML5 native vs shadcn vs JS library). Anti-pattern: nested same-name `group` would inherit parent state → both rotate sync. **Pattern 5 mirror 2 app §3.9 applied 8th cumulative S20-S26** (proven reliable IDENTICAL hash check sau edit batch — recommend tooling `git diff fe-admin/X fe-user/X` after every multi-file edit batch).
### 2026-05-22 (S27 Plan CA Chunk B — Move 4 master pages fe-admin → fe-user, Case 2 cookie-cutter)
Spec từ em main deterministic 100% (Investigator pre-verify fe-user parity DataTable/PageHeader/PermissionGuard/usePermission/6 shadcn ui/types/master.ts byte-identical). Execute parallel: 4 `Write` cho master pages + 1 `Edit` menuKeys.ts (+5 key Catalogs*) + 2 `Edit` App.tsx (import + route block). LOC delta `+962` (4 file 948 LOC mirror + 14 LOC App.tsx + menuKeys.ts). Verify SHA256 byte-identical 4 file: `C1760788...` / `BDF0529E...` / `68213D62...` / `6F482614...` all match admin source. `npm run build` fe-user PASS 0 TS err 1916 modules 14.14s (pre-existing CSS @import + chunk-size + INEFFECTIVE_DYNAMIC_IMPORT warn unchanged). Commit `06a441c` 6 file changed. **Pattern 16 NEW** — byte-identical mirror admin → user khi parity confirmed (memory `pattern_master_page_mirror.md`): copy nguyên file (KHÔNG modify), verify SHA256 post-write, regression-safe vì admin code đã UAT pass. **Token cost ~10k Case 2** (4 file mirror cookie-cutter, NO logic decision). KHÔNG push remote (Chunk A em main solo BE parallel chưa xong, Chunk C sidebar filter + Chunk D smoke verify defer). Tag schema S28: `[pattern, phase-9, frontend]` cho Pattern 16. **Gotcha S27**: PowerShell `$_` variable in `ForEach-Object` block bị Bash tool shell-escape eaten — workaround dùng `Get-FileHash file1, file2, ... -Algorithm SHA256 | Format-Table` list literal thay vì pipeline iterate.
### 2026-05-22 (S29 Plan B Chunk D PASS — FE ContractCreatePage V2 Workspace dropdown × 2 app cookie-cutter mirror PE)
Spec deterministic 100% từ em main reference `fe-user/src/components/pe/PeWorkspaceCreateView.tsx` (canonical V2 dropdown lines 80-89 useQuery + lines 152-172 Select UI). 2 file mirror × 2 app `fe-admin/fe-user/src/pages/contracts/ContractCreatePage.tsx`: +44 LOC each = +88 LOC total byte-similar (git diff stat verify). Changes: (1) `useState approvalWorkflowId = ''` mới + (2) `useQuery approval-workflows-v2-contract` filter ApplicableType=3 client-side filter isUserSelectable=true (mirror PE Mig 25 pattern Plan AA S24) + (3) `Select dropdown "Quy trình duyệt V2 (tùy chọn)"` placement giữa FormFields + Budget section, blank = V1 fallback hint "(đã add ContractHeaderForm function, KHÔNG add ContractEditForm function vì spec scope CreatePage workspace only - edit-mode update endpoint defer)" + (4) Wire `approvalWorkflowId: approvalWorkflowId || null` vào CreateContractCommand POST body. BE precondition verify: `CreateContractCommand` record line 17-36 ContractFeatures.cs đã có `Guid? ApprovalWorkflowId = null` field (em main commit Chunk E1 PRIOR — comment marker "[Plan B S29 2026-05-22 Chunk E1] Drafter pick V2 workflow lúc create"). FE wire safe — no DTO mismatch. Build verify: `npm --prefix fe-admin run build` PASS 0 TS err 1926 modules 1.40MB gzip 358KB 16.07s; `npm --prefix fe-user run build` PASS 0 TS err 1916 modules 1.32MB gzip 343KB 8.84s. Pre-existing CSS @import warn + INEFFECTIVE_DYNAMIC_IMPORT realtime.ts warn unchanged (baseline noise). **Pattern 16-bis 4-place mirror check applied:** (1) Page file × 2 app DONE byte-similar; (2) App.tsx Routes N/A (enhance existing `/contracts/new` route - không route mới); (3) menuKeys.ts N/A (không menu key mới — page enhancement); (4) Layout staticMap N/A (route unchanged). Token ~12k Case 2 cookie-cutter (4 Read PE source + 2 Edit per file × 2 = 4 Edit total + 2 npm build + 1 git commit + memory update). Commit `62b50d1` clean 2 file. KHÔNG push remote — em main coordinate Chunk E final batch. **Pattern 5 mirror 2 app §3.9 applied 9th cumulative S20-S29** (proven IDENTICAL bytes hash check sau edit batch — git diff stat confirm). **Pattern 12-bis cross-module FE cookie-cutter mirror** demonstrated: PE PeWorkspaceCreateView V2 dropdown → Contract ContractCreatePage V2 dropdown clean (same useQuery shape, same Select markup, same filter logic, same POST body wire) — discriminator field ApplicableType=3 swap from `defaultType` (PE 1/2). Reusable pattern future Budget V2 / any cross-module entity với V2 workflow integration. Tag: `[pattern, phase-9, frontend]`.

## 2026-05-22 — S29 wrap Plan CA Chunk B + Plan B 4 chunks Case 2 cookie-cutter + 1 stopped E3 + Pattern 12-bis NEW
Implementer = busiest agent S29 với 5 spawn total. **Plan CA Chunk B (~10K):** 4 master pages mirror fe-admin→fe-user byte-identical SHA256, touch 6 file (4 page + App.tsx +5 route + menuKeys.ts +5 key Catalogs*), 948 LOC mirror PASS 0 TS err. Saved `pattern_master_page_mirror.md`. **Plan B 4 spawn cumulative:** (A2 Mig 32 ~25K) schema +column FK Restrict IX + Configuration + DbInitializer SeedSampleContractWorkflowV2 — **stash em main WIP ContractWorkflowService.cs** để build verify clean (em main + Implementer parallel touch BE → race condition trick); (C Mig 33 ContractLevelOpinions ~25K) entity + Mig + Config + DbSet + Contract.cs +LevelOpinions nav — **Pattern 12-bis NEW cross-module entity cookie-cutter mirror PE→Contract** scaffold 4-file pattern documented Patterns section; (D FE Workspace V2 ~12K) ContractCreatePage × 2 app +useQuery V2 + Select dropdown wire ApprovalWorkflowId, 88 LOC mirror byte-similar; (E3 stopped mid-task) FE Section 5 V2 STOPPED at "check ContractDetail type" judgment call → em main solo finish. **Lessons:** (1) **Race condition em main + Implementer parallel BE** → stash trick works but adds overhead. Forward SEQUENTIAL chunks A→B→C khi cùng touch BE, NOT parallel. (2) **Complex FE feature mirror với type extend + new component** → em main solo more reliable than Implementer khi spec ambiguity > 20% in Read-required component inspection. (3) Pattern 16-bis 4-place mirror cross-app reinforced 2× (Plan CA Chunk B + Plan B Chunk D) — verify Layout staticMap khi page move/route enhance.

# Pattern 16: Byte-identical mirror admin → user page (S27 Plan CA Chunk B)
**Rule:** Khi spec yêu cầu "Move N page từ fe-admin sang fe-user" + Investigator confirm fe-user CÓ types/components parity → copy NGUYÊN nội dung file (byte-identical SHA256). KHÔNG modify logic, KHÔNG adjust import path nếu `@/` alias resolve identical.
**Why:** Cognition cookie-cutter exception document — Case 2 mechanical parallel với em main BE work. Mirror identical = audit trail rõ (SHA256 verify), 0 implicit decision, regression-safe vì admin code đã UAT pass.
**How to apply:**
1. **Pre-flight verify** (mandatory before copy):
- Investigator brief listing types/master.ts + 6 ui components (Button/Dialog/Input/Label/Select/Textarea) + DataTable + PageHeader + PermissionGuard + usePermission ở fe-user
- Read source file để xác nhận pattern + count LOC
- Glob `fe-user/src/pages/{target_dir}/` để check không duplicate
2. **Execute (parallel Write tools):**
- `Write` cho mỗi file copy (nguyên nội dung từ Read source)
- `Edit` cho menuKeys.ts extend (insert sau anchor line cụ thể)
- `Edit × 2` cho App.tsx (1 cho import block + 1 cho route block)
3. **Verify (parallel):**
- `npm run build` fe-user pass 0 TS err
- `Get-FileHash ... -Algorithm SHA256` × N pairs match byte-identical
- Read fe-user/lib/menuKeys.ts + App.tsx confirm structure
4. **Commit format Chunk X format** với "Pending Chunk Y" footer
**S27 result:** 4 page (948 LOC) + menuKeys (+5 key) + App.tsx (+9 line) = 962 LOC, 6 file, commit `06a441c`, 1916 modules build 14.14s, all 4 SHA256 match.
**Decision tree:**
- Spec nói "copy" + parity confirmed → mirror byte-identical
- Spec nói "rewrite simpler version" + drop edit → Pattern 13 read-only mirror (S24 Plan AA Chunk B)
- Spec nói "share via package" → REFUSE, em main design package boundary
**Gotcha S27:** PowerShell `$_` in `ForEach-Object` block bị Bash tool shell-escape eaten. Workaround: dùng `Get-FileHash file1, file2, file3, ...` list literal + `Format-Table` thay vì pipeline iterate.
