## 🎯 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>

|
||
```
|
||
|
||
### 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)
|
||
|
||
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.
|
||
|
||
### 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.
|
||
|
||
### 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).

- MediatR `12.4.1` (14 fail DI)
|
||
- Swashbuckle `6.9.0` (10 conflict OpenApi 2)
|
||
- Node engines `>= 20` + CI pin `20.x` (bài học NamGroup, memory `feedback_node_cicd`)

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`.

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`).

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).

| C1 Curate cicd-monitor 72KB | ❌ REFUSE #1 (judgment §6.5 KEEP vs CUT) | Em main solo CORRECT |

| C2-C4 Curate 3 agent MEMORY | ❌ REFUSE #1 same | Em main solo CORRECT |
|
||
| C5 Audit drift §6.4 + §9.4 | ❌ REFUSE #1 same | Em main solo CORRECT |
|
||
| A3.1 Write 5 PS scripts | ✅ ACCEPT Case 2 (5 file cookie-cutter mirror pattern) | **Implementer would ACCEPT** - em main miss delegate opportunity |
|
||
| A3.2 Dashboard HTML + generator | ❌ REFUSE #7 (first time pattern, no precedent) + #2 UX design needed | Em main solo CORRECT |

**Verdict: 2/8 task lẽ ra delegate được Implementer (Case 1+2) nhưng registry empty → em main forced solo.** Net loss ~30 phút time + miss cookie-cutter mirror discipline. Pattern 20 NEW saved foundation: "**5 PS scripts mirror pattern** — start/stop/status/dashboard/boot family cùng ASCII discipline + same Write-Host structure + same try-catch pattern" reusable cho future infra automation. **Pending post-restart CLI S28+:** Implementer Case 2 spawn cho any mass file mechanical refactor.
