Raw Blame History

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)
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:

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:

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:

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.

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.

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.

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.

  • 2026-05-22 (S28 wrap — Layer A governance distributed active, Implementer policy local apply): S28 em main solo cả buổi (KHÔNG Implementer work code thực sự). Timeline: t1 RAG ROI verdict marginal-short/transform-long → t2 bro feedback "ghi mọi tương tác" → t3 em đề xuất 2-week monitoring 5 metric → t4 bro caught self-authorize cross-project rule mistake → t5 governance broadcast Layer A active 3-Layer distributed scope-down về SOLUTION_ERP self-discipline. Implementer perspective về Layer A governance: (1) Pattern proven ≥ 2× qualifies Layer B nominate. Pattern 7 per-NV admin opt-in flag (Mig 29 AllowDrafterEdit + Mig 30 AllowApproverEditSection1 + Mig 31 AllowEarlyApprove + AllowDelegate) đã proven 4× — strong candidate Layer B promote khi unfreeze. (2) Tag schema mandatory áp dụng forward: store Pattern chunk với format [pattern, phase-<N>, <bc>] — vd Pattern 19 HTML details tree view → [pattern, phase-9, frontend]; Pattern 18 FE userMap fallback → [pattern, phase-9, frontend]; Pattern 16 preventive batch fix → [pattern, phase-9, cross-cutting].

  • 2026-05-22 (S27 wrap-up em main proxy - retrospective REFUSE analysis): Em main S27 SOLO cả buổi vì registry KHÔNG load (per pitfall VIPIX #1+#2). Retrospective analysis 6 task S27 vs ACCEPT/REFUSE criteria:

    Task S27 Implementer fit? Verdict
    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
    A4 rag-onboarding-guide.md 421 lines ❌ REFUSE #2 (docs writing judgment) Em main solo CORRECT
    F1 Qdrant Web UI fix ❌ REFUSE #4 (bug reasoning chain) Em main solo CORRECT
    F2 4 agent files fix model:inherit ✅ ACCEPT Case 1 (4 file mechanical same edit) Implementer would ACCEPT - em main miss delegate opportunity

    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.
