## GROUNDTRUTH: PDF-Derived Specifications

### Architecture (From PDF 1: Vue 3·TypeScript OMS·WMS·ERP 아키텍처.pdf)

**Recommended Architecture**: Domain-Centric Modular Monolith + Layered Internal Structure

```
Application Shell (routing, auth, global state)
    ↓
Workflow (cross-domain orchestration)
    ↓
Module Presentation (Vue, Pinia, Router)
    ↓
Application Use Case (business logic entry points)
    ↓
Domain (entities, value objects, rules)
    ↑
Infrastructure Adapter (API clients, DB, cache)
```

**Core Principles** (PDF explicit):
1. Module by business domain, not by screen
2. Vue, Pinia, Router confined to Presentation layer only
3. Domain layer NEVER imports Vue/HTTP libraries
4. API DTO ≠ Screen Model ≠ Domain Model (3-way separation)
5. Inter-module access only via public index.ts
6. Distinguish common UI from business rules
7. Workflows coordinate multi-domain logic

**Folder Structure** (PDF prescribed):
```
src/
├─ app/              (shell, bootstrap, config)
├─ shared/           (primitives, fields, forms, data-grid)
├─ modules/
│  ├─ order/         (OMS domain)
│  ├─ inventory/     (WMS domain)
│  └─ accounting/    (ERP domain)
├─ domain/           (entities, repositories, use cases)
├─ infrastructure/   (API clients, adapters)
└─ workflows/        (multi-domain orchestration)
```

### CRUD Templates (From PDF 2: 공통 CRUD 화면 템플릿 상세 명세.pdf)

**11 Standard Template Types**:

| Template ID | Screen Type | Representative Business | Key Features |
|-----------|-----------|----------------------|--------------|
| TPL-LIST-01 | List/Search | Orders, inventory, vouchers | Saved queries, column preferences, multi-filter, bulk actions, async export |
| TPL-CREATE-01 | Single Create | Vendor, product, simple order | Direct input, simple validation |
| TPL-CREATE-02 | Header-Line Create | Order, PO, receipt, voucher | Master-detail, line auto-calc, currency standardization |
| TPL-CREATE-03 | Wizard Create | Complex order, return, contract | Multi-step workflow, conditional logic, branch preview |
| TPL-DETAIL-01 | Detail View | Order detail, receipt detail, voucher detail | Tabs (Info, History, Attachments, Audit), read-only by default |
| TPL-EDIT-01 | General Edit | Master data, order provisional state | Full form edit, save/cancel, undo/redo |
| TPL-BULK-01 | Bulk Edit | Owner, due date, status batch change | Multi-row mutation, impact preview |
| TPL-DELETE-01 | Delete | Unused temp data | Soft-delete only, never hard-delete live records |
| TPL-CANCEL-01 | Cancel/Reversal | Order cancel, shipment cancel, voucher reversal | Create reversal transaction, NOT overwrite original |
| TPL-APPROVAL-01 | Approval/Rejection | PO approval, voucher approval | Workflow state machine, approval reason capture |
| TPL-HISTORY-01 | Change History | Value changes, state transitions, system processing | Before/after comparison, worker, reason, source trace |

**Screen Layout (PDF mandatory)**:
```
┌────────────────────────────────────────────────┐
│ Global Header (system switch, org select,      │
│               global search, notifications)     │
├────────────────────────────────────────────────┤
│ Breadcrumb                                     │
├────────────────────────────────────────────────┤
│ Page Header (title, ID, status, last editor)  │
├────────────────────────────────────────────────┤
│ Context Bar (facility, warehouse, date, lock) │
├────────────────────────────────────────────────┤
│                                                │
│ Main Content (list, form, detail)             │
│                                                │
├────────────────────────────────────────────────┤
│ Sticky Action Bar ([Cancel] [Draft] [Save])   │
└────────────────────────────────────────────────┘
```

### Input Component Hierarchy (From PDF 3: 입력 컴포넌트 상세 명세.pdf)

**4 Layers** (strict separation):

#### Layer 1: Primitive
Visual + interaction foundation (no business knowledge).

**Components** (10 types):
- TextInput, Button, Checkbox, Radio, Select
- Popover, Dialog, Calendar, Listbox, Grid Cell

#### Layer 2: Typed Field
Data type awareness (format, validation, but no domain).

**Components** (8 types):
- StringField, IntegerField, DecimalField
- DateField, DateTimeField, CurrencyField, PercentageField, CodeField

#### Layer 3: Domain Field
Business domain understanding (item lookup, warehouse context).

**Components** (10 types):
- ItemLookup, CustomerLookup, WarehouseLookup, LocationLookup
- QuantityField, MoneyField, LotField, SerialNumberInput
- BusinessRegistrationNumberField, AccountLookup

#### Layer 4: Business Composite
Multiple fields + business rules (e.g., tax calculation).

**Components** (8 types):
- AddressEditor, OrderLineEditor, InventoryAllocationEditor
- LotSerialEditor, TaxAmountEditor, DeliveryScheduleEditor
- BarcodeWorkInput, ApprovalReasonEditor

**Strict Rule** (PDF emphasis):
> "복잡한 컴포넌트가 거대한 범용 컴포넌트로 변질되지 않게 한다."
> (Prevent complex components from degenerating into bloated monoliths.)

Business Composites own field combinations, NOT full-screen logic.

---

### Design Principles (From PDF 4: CRUD 화면 및 입력 컴포넌트 상용화 제안.pdf)

**Core Principle**: TRANSACTIONS, not CRUD

Business transactions extend beyond simple Create/Read/Update/Delete:

| Category | Operations | Example |
|----------|-----------|---------|
| **Inquiry** | Search, filter, compare, aggregate, download | Order list with saved filters |
| **Creation** | Direct input, copy, template, external sync | Order creation from EDI |
| **Modification** | Inline edit, bulk edit, record edit | Status batch change |
| **State Transition** | Approve, confirm, allocate, close, suspend, release | Order confirmation → inventory reserve |
| **Exception Handling** | Cancel, return, reversal, reprocess, correction | Order cancel (reversal transaction) |
| **History** | Before/after, worker, reason, source trace | Audit trail for regulatory compliance |
| **Collaboration** | Comments, attachments, approval requests, handoff | Approval workflow + reason capture |
| **AI Assistance** | Value recommend, anomaly detect, input correct, explain | Predictive analytics for order priority |

**Critical**: Completed data is never deleted or overwritten. Use reversal transactions instead.

---

### Phased Rollout Strategy (From PDF 5: 단계별 구축 백로그.pdf)

**Phased Approach** (NOT all-at-once):

```
0. Current State Analysis & Standard Decisions
   ↓
1. Vue 3·TypeScript Development Foundation
   ↓
2. Common Models & API Boundary
   ↓
3. Primitive & Input Components
   ↓
4. CRUD Screen Templates
   ↓
5. OMS Order Pilot (order registration)
   ↓
6. WMS Receipt/Picking Pilot (warehouse floor validation)
   ↓
7. ERP Voucher/Approval Pilot (accounting integration)
   ↓
8. Integrated Workflow & Batch Processing
   ↓
9. AI/AX Enhancements
   ↓
10. Legacy Migration & Operational Stability
```

**Rationale** (PDF explicit):
> "처음부터 OMS·WMS·ERP 전체를 동시에 구현하지 않는다."
> (Don't implement OMS·WMS·ERP simultaneously from day one.)
> "주문 등록처럼 입력·조회·계산·상태 전이·재고 연계가 모두 포함된 대표 업무를 먼저 구현하여 구조의 실효성을 검증한다."
> (Validate architecture with representative end-to-end business: order registration includes input, inquiry, calculation, state transition, inventory linking.)

**Work Hierarchy** (PDF prescribed):
```
Initiative (OMS·WMS·ERP Unified Business Platform)
└─ Epic (e.g., "Order Registration Standardization")
   └─ Feature (e.g., "Header-Line Order Create")
      └─ Story (e.g., "User saves order with vendor + item")
         ├─ Task: OrderFormModel implementation
         ├─ Task: CreateOrderUseCase implementation
         ├─ Task: API Mapper
         └─ Task: E2E test implementation
```

**Priority Matrix** (PDF defined):
| Level | Meaning | Examples |
|-------|---------|----------|
| P0 | Service operation + data consistency critical | Order state machine, inventory reserve atomicity |
| P1 | Required for first business release | OMS order pilot |
| P2 | Operational efficiency + scalability | Bulk processing, async export |
| P3 | Enhancement or optional feature | AI recommendations, advanced reporting |

**Task Sizing** (PDF criteria):
| Size | Effort | Guidance |
|------|--------|----------|
| XS | <0.5 day | Simple change, no decomposition needed |
| S | 1-2 days | Standard task, low risk |
| M | 3-5 days | Multi-component, moderate coordination |
| L | 1 sprint | Substantial, can break into substories |
| XL | >1 sprint | MUST be decomposed, never assign as single ticket |

## 30 STRATEGIC PRINCIPLES (Integrated with PDF Specifications)

### Principle 1: SOLID (Software Design)
**Application**: Architecture layer in PDF 1
- **S**ingle Responsibility: Each module (order, inventory, accounting) owns one domain
- **O**pen/Closed: Add new domains without modifying existing layers
- **L**iskov Substitution: All Field components swap without caller changes
- **I**nterface Segregation: Primitive doesn't bloat with domain knowledge
- **D**ependency Inversion: Domain layer depends on repositories (abstract), not HTTP client (concrete)

**Verification Checkpoint**: Code review: no circular imports, all domain-to-infrastructure flow one-way

---

### Principle 2: Code Refactoring (Continuous)
**Application**: Prevent "complex component degenerates into monolith" (PDF explicit warning)
- Extract reusable patterns at 3+ usage point threshold
- Componentize OrderLineEditor when same fields+logic appear in order, PO, receipt
- Break down TPL-CREATE-02 if >500 lines (template too complex)

**Verification Checkpoint**: Component size < 300 lines (.vue file), dependencies < 5 imports

---

### Principle 3: Data Consistency (SSOT)
**Application**: "화면과 서버의 데이터 해석이 달라지지 않게 한다" (PDF 1.1)
- API DTO ≠ Screen Model ≠ Domain Model (PDF explicit 3-way separation)
- All currency decimals conform to PostgreSQL NUMERIC(19,4) standard
- Quantity unit (each, kg, meter) enforced server-side, never client-side formatting

**Verification Checkpoint**: Schema review + integration test: CurrencyField value round-trip == API response

---

### Principle 4: Parsimony (No Gold-Plating)
**Application**: Template specification precise, not aspirational
- TPL-LIST-01 includes saved filters + bulk actions (PDF spec)
- TPL-CREATE-03 (wizard) only for complex orders (PDF: "복합 주문")
- Reject "nice-to-have" export formats until P1 release proven stable

**Verification Checkpoint**: Feature checklist matches PDF requirement, no extras (backlog → Phase 12)

---

### Principle 5: Normalization (Database)
**Application**: Schema design for master data (vendors, items, GL accounts)
- 3NF minimum (vendor table: vendor_id → name, country; no address duplication)
- Separate master from transactional (items in item_master, not repeated in order_line)
- LOT/Serial data as separate entity (denormalized only if 100M+ rows proven slow)

**Verification Checkpoint**: ER diagram review, no repeating groups, referential integrity 100%

---

### Principle 6: Denormalization (Justified)
**Application**: Only after performance proof
- Cache order total instead of sum(order_line.qty * price) IFF
  - Query <200ms target breached (P95 measurement)
  - Denormalization reduces to <100ms (proof required)
  - Cascade update logic fully tested (no orphaned totals)
- Example: order_summary.total_amount auto-updated via trigger

**Verification Checkpoint**: Load test before/after, TTL strategy for cache invalidation

---

### Principle 7: Process Simplification
**Application**: Validate BEFORE automating
- Manual order entry: 5 steps (enter customer → items → dates → validate → save)
  - Automate only after 100 live orders confirm 5-step workflow is universal
  - Never assume "users want copy-paste bulk" until stated explicitly
- Approval workflow: Confirm 2-person dual-approval rule is actual business requirement, not preference

**Verification Checkpoint**: Workflow diagram reviewed by domain experts (OMS user, WMS supervisor, accounting manager)

---

### Principle 8: Patterns & Design
**Application**: Reusable patterns for business transactions
- **Pattern 1**: List + Detail (TPL-LIST-01 + TPL-DETAIL-01 pair)
- **Pattern 2**: Header-Line with auto-calc (TPL-CREATE-02, e.g., order → line items → total)
- **Pattern 3**: State Machine (approve → confirm → ship, never skip backward)
- **Pattern 4**: Reversal Transaction (cancel = create opposite entry, not delete)

**Verification Checkpoint**: Common pattern identified for 3+ templates → abstract into reusable module

---

### Principle 9: Standardization (Conventions)
**Application**: Consistent naming, API contracts, component interfaces
- Field naming: `quantity`, `quantity_unit`, `quantity_reserved` (not `qty`, `qtyUnit`, `reserved_qty`)
- API endpoints: `/api/orders/{orderId}/lines` (nested resource) not `/api/orders/lines?order_id=...`
- Component props: `modelValue`, `@update:modelValue` (Vue 3 standard, not custom `value`/`onChange`)
- Error codes: ERR_ORDER_VALIDATION_QUANTITY_EXCEEDS_STOCK (fully qualified, i18n key)

**Verification Checkpoint**: Linting rules enforce naming (ESLint), OpenAPI schema validation, Storybook prop documentation

---

### Principle 10: Structuring (Layered Architecture)
**Application**: PDF 1 architecture enforced
- Presentation Layer (Vue, Pinia, Router): handles user interaction, routes, component state
- Application Layer (Use Cases): orchestrates domain logic (CreateOrderUseCase)
- Domain Layer (Entities, Value Objects, Rules): business logic, NO Vue/HTTP knowledge
- Infrastructure Layer (Adapters): API clients, DB repositories

**Verification Checkpoint**: No imports from higher layers into lower (e.g., domain never imports presentation)

---

### Principle 11: Vibes Coding (Cognitive Load)
**Application**: Clear naming, minimal mental overhead, consistency
- Component naming: `CustomerLookup` (not `CustmrSrch`, not `CustomerAutocompleteSearchWithValidation`)
- Variable names: `orderTotal`, not `t` or `sum_$_from_items`
- Error messages: "Order quantity exceeds available stock (reserve: 100, order: 150)" (context, not cryptic code)
- Code structure: 1 function = 1 responsibility (CreateOrderUseCase doesn't also handle price calculation)

**Verification Checkpoint**: Pair programming review, PR comment: "readable without documentation?"

---

### Principle 12: Hallucination Prevention (Ground Truth)
**Application**: Explicit test-driven, no assumptions
- Requirement: "Save order with customer + items"
  - NOT assumed: "Orders can have unlimited line items" (test: max 999 lines per business rule)
  - NOT assumed: "Items can be duplicated in one order" (test: confirm if allowed or enforce uniqueness)
  - Verified via: PDF spec, stakeholder sign-off, acceptance test
- Never code "nice-to-have" features without explicit P0/P1 tag

**Verification Checkpoint**: Acceptance test references PDF page, stakeholder email, or JIRA requirement, not general assumption

---

### Principle 13: Ground Truth & Reproducibility
**Application**: All results deterministic, traceable to source
- Test data: seed.sql from GatherTradingData.json (not random generation)
- Calculations: CurrencyField(100.50, "USD") → API response `{"amount": "100.5000"}` (4 decimals, always)
- Audit trail: OrderCreated event includes user, timestamp, IP, all changes logged
- Reproducible: QA can replay issue from 2 weeks ago using same test data snapshot

**Verification Checkpoint**: E2E test passes in CI pipeline, seed data versioned in git, audit log exported for review

---

### Principle 14: Traceability (Audit)
**Application**: Complete history of all changes
- Create: `audit_log.operation = 'INSERT', changed_by = user_id, changed_at = now()`
- Update: `audit_log.operation = 'UPDATE', old_value = '{"status": "DRAFT"}', new_value = '{"status": "CONFIRMED"}', reason = 'Admin action'`
- Delete: `audit_log.operation = 'DELETE'` (soft-delete only, never erase)
- Reversal: `audit_log.related_transaction_id = original_order_id` (link cancel to original)

**Verification Checkpoint**: All CRUD operations produce audit_log row, audit UI queries pass, compliance report shows 100% coverage

---

### Principle 15: Reliability (Fault Tolerance)
**Application**: Graceful degradation, auto-recovery
- Network failure: Retry 3x with exponential backoff (1s, 2s, 4s), then user-friendly error
- Validation failure: Clear error message with fix guidance ("Quantity exceeds stock by 50 units, reduce or request allocation")
- State inconsistency: Transaction rollback (order saved + inventory reserved atomically, no orphaned state)
- Cascade failure: If GL account API down, order can still save (audit flag: "GL posting pending")

**Verification Checkpoint**: Chaos engineering test, network latency/loss simulation, error handling 100% tested

---

### Principle 16: Technical Debt (Zero New, Reduce Old)
**Application**: No shortcuts, audit existing debt
- No: hardcoded user IDs, no-verify deployments, TODO comments without ticket
- Yes: Refactor one legacy component per sprint (e.g., old BaseForm → new Typed Field approach)
- Quarterly audit: Debt spreadsheet (complexity, security, performance) with mitigation plan

**Verification Checkpoint**: Debt review in sprint retrospective, tech lead sign-off on any debt deferral

---

### Principle 17: Componentization (Smart + Dumb)
**Application**: Clear separation (PDF implicit in 4-layer hierarchy)
- **Dumb (Presentation)**: Primitive, Typed Field (TextInput, CurrencyField) — props in, events out, zero side effects
- **Smart (Business Logic)**: Use Cases (CreateOrderUseCase), Stores (OrderStore) — owns state, API calls, calculations
- **Composite (Pattern)**: OrderLineEditor (coordinates field + validation + auto-calc) — re-used in multiple contexts
- **Page (Container)**: OrderCreatePage (composes OrderForm + UseCase orchestration) — specific to single business process

**Verification Checkpoint**: Storybook for Dumb components (no backend needed), separate integration test for Smart (mocked API)

---

### Principle 18: Professional Approach (정공법)
**Application**: Best practices, no cutting corners
- Code review before merge (all changes reviewed, approved)
- Pair programming for high-risk code (state machine logic, data validation)
- Documentation: API contracts (OpenAPI), component props (TypeScript types), workflows (ADRs)
- Testing: Unit (70%+), Integration (API mocks), E2E (Playwright)
- Security: OWASP validation, RBAC tests, SQL injection prevention (parameterized queries)

**Verification Checkpoint**: PR checklist: tests pass, docs updated, no security warnings, code review approved

---

### Principles 19-30 (Continuation for Comprehensiveness)

**Principle 19: Type Safety (TypeScript)**
- All components export TypeScript interfaces for Props, Emits, Model
- No `any` type, strict mode enabled
- Domain entities typed (Order, OrderLine, etc.)

**Principle 20: Accessibility (WCAG 2.1)**
- All fields: label linked, ARIA attributes, keyboard navigation
- Colors: WCAG AA contrast ratio (4.5:1 for text)
- Form errors: announced to screen readers

**Principle 21: Internationalization (i18n)**
- All user-facing text: externalized to .i18n.ts files
- Supported languages: Korean, English, Japanese (per PDF)
- Date/currency formatting: locale-aware (not hardcoded)

**Principle 22: Performance (Response Time)**
- API P95 response: <250ms
- Component render: <100ms
- Bundle size: <500KB (gzip)
- Measured: Lighthouse, browser DevTools, load testing

**Principle 23: Security (OWASP)**
- Input validation: Server-side + client-side redundant
- XSS prevention: Never innerHTML, use Vue templates
- CSRF tokens: All state-changing requests
- SQL injection: Parameterized queries only (Dapper/TypeORM)

**Principle 24: Error Handling (User-Centric)**
- Show: "Order cannot be canceled after shipment confirmed" (clear business rule)
- NOT: "SQL error: constraint violation" (technical jargon)
- Recovery: Suggest next action ("Contact admin to unlock" / "Request manager approval")

**Principle 25: API Consistency (REST Contracts)**
- GET /api/orders → list with pagination
- POST /api/orders → create
- GET /api/orders/{id} → detail
- PUT /api/orders/{id} → full update
- PATCH /api/orders/{id} → partial update
- DELETE /api/orders/{id} → soft-delete
- All responses: 200 success, 400 validation, 401 auth, 403 forbidden, 404 not found, 500 server error

**Principle 26: Testing Pyramid (Automated)**
- Unit (50%): Components, Use Cases, Validation rules
- Integration (30%): API + Store + Component workflows (with mock backend)
- E2E (20%): Critical user journeys (order create → confirm → ship)
- Coverage: 70%+ code coverage, 100% critical path coverage

**Principle 27: Deployment Pipeline (CI/CD)**
- Automated: Code merge → lint → test → build → deploy-staging → health-check
- Manual gate: Staging validation → production approval
- Rollback: Blue-green deployment, 1-click revert to previous version
- Monitoring: Sentry (errors), DataDog (performance), uptime checks

**Principle 28: Documentation (Durable)**
- Architecture Decision Records (ADRs) for major choices
- OpenAPI 3.0 for all APIs (auto-generated, never stale)
- Storybook for component library (visual + prop docs)
- README per module (setup, usage, testing)
- Wiki (deployment, ops runbooks, troubleshooting)

**Principle 29: Team Discipline (Enforcement)**
- Code review checklist enforced (ESLint, type-check, test coverage)
- Commit message standard: type(scope): subject (feat, fix, docs, refactor, test)
- Git workflow: feature branches → PR → squash merge (clean history)
- Ownership: Module lead responsible for code quality + debt in their domain

**Principle 30: Continuous Improvement (Iteration)**
- Weekly retrospectives: What went well, what failed, action items
- Monthly metrics review: Test coverage, bug count, deployment frequency, lead time
- Quarterly strategy: Architecture debt audit, technology updates, team skill development
- Post-mortems for P1+ incidents: Root cause, prevention, learning documented

- Template stubs demonstrate layout (no business logic yet)

---

### Phase 3-4: OMS Pilot & Workflows (Week 7-10)

**Objectives** (Principle 4: validate architecture with real business):
- Implement complete order creation workflow (input + state + inventory)
- Prove component hierarchy + API integration works
- Validate transaction model (not CRUD)

**Deliverables**:
- CreateOrderUseCase (business logic)
- OrderFormModel (screen state)
- Order API mapper (DTO ↔ Domain)
- TPL-CREATE-02 (header-line order form) fully functional
- E2E test: user creates order → inventory reserved → confirmation email sent
- Audit trail: all changes logged

**30 Principles Applied**:
1. SOLID: Domain model independent of API/UI (Principle 1)
2. Consistency: 3-way Model separation enforced (Principle 3)
3. Patterns: Header-line pattern documented, reusable (Principle 8)
4. Traceability: Order creation + all field changes audited (Principle 14)

6. Transactions: Use reversal model (cancel = create opposite), not delete (Principle 16)
7. Type Safety: OrderFormModel fully typed (Principle 19)
8. Error Handling: Clear messages for invalid order (Principle 24)
9. Testing: Happy path + error cases tested (Principle 26)
10. Documentation: Order creation workflow documented (Principle 28)

**Exit Criteria**:
- Order creation E2E test passes
- Audit log captures all changes
- Inventory reserve confirms before order save
- Type errors: 0
- Test coverage: 80%+ (higher for critical path)
- Performance: Order save <250ms P95
- Security: CSRF token + input validation verified

### Phase 5-7: WMS & ERP Pilots (Week 11-16)

**Objectives** (Principle 4: validate each domain):
- Implement WMS receipt workflow (prove warehouse floor compatible)
- Implement ERP voucher + approval (prove accounting integration)
- Demonstrate cross-domain workflow

**Deliverables**:
- ReceiptUseCase (receipt validation, lot/serial)
- VoucherUseCase (GL posting, approval chain)
- WMS & ERP pilots: 90% feature complete
- Integration test: order → receipt → GL posting (multi-domain flow)

**Exit Criteria**:
- Both pilots pass P1 acceptance criteria
- Cross-domain data consistency verified
- Audit trail for all domains complete
- 80%+ test coverage maintained
- Performance targets met
- Approval workflow functional

### Phase 8-10: Production Readiness (Week 17-22)

**Objectives**:
- Load testing, security hardening
- Documentation, training
- Deployment preparation

**Exit Criteria**:
- Load test: 100 concurrent users, <250ms P95
- Security audit: 0 critical vulns
- Disaster recovery tested
- UAT pass with end-users
- Documentation 100% complete
- Go-live approved

## ANTI-PATTERNS (What to Avoid)

**❌ Anti-Pattern 1**: "Bloated Business Composite"
- Example: OrderFormComponent owns order create + item search + inventory check + GL posting (no separation)
- Fix (Principle 2, 17): Break into OrderForm (UI) → CreateOrderUseCase (logic) → InventoryService (domain)

**❌ Anti-Pattern 2**: "Hallucinated Requirements"
- Example: "Let's add AI recommendation" without P0/P1 tag, no user request
- Fix (Principle 12): Every feature in backlog traces to PDF, stakeholder request, or JIRA ticket

**❌ Anti-Pattern 3**: "The Monolith Grows"
- Example: Primitive TextInput gradually gains domain logic (currency formatting, tax validation)
- Fix (Principle 2, 17): Extract to Typed Field (CurrencyField) or Domain Field (TaxAmountField)

**❌ Anti-Pattern 4**: "Forgotten Audit Trail"
- Example: Order status changed in DB, but no audit_log row (no traceability)
- Fix (Principle 14): Trigger on all UPDATE/DELETE, manual log in code for application logic

**❌ Anti-Pattern 5**: "Manual Process Not Validated"
- Example: Assume users want bulk order import, but never confirm with 5 OMS users
- Fix (Principle 7): Workflow diagram reviewed + walkthrough with domain expert before coding

**❌ Anti-Pattern 6**: "Circular Dependency"
- Example: Domain layer imports Use Case (should be opposite)
- Fix (Principle 1): Dependency Inversion, domain does not know about infrastructure/presentation

**❌ Anti-Pattern 7**: "Test Coverage Without Meaningful Tests"
- Example: 70% coverage but only happy-path tests, error scenarios untested
- Fix (Principle 26): Critical path 100%, all error cases tested, mutation testing for quality

**❌ Anti-Pattern 8**: "Security Debt"
- Example: No CSRF token on order save, SQL built with string concat
- Fix (Principle 23): Security review before merge, parameterized queries mandatory

## GOVERNANCE & CHECKPOINTS

### Daily (Scrum)
- Each task update: Principle applied? Risk identified? Blocker?

### Weekly (Retrospective)
- Velocity, test coverage, technical debt status
- Anti-patterns spotted?
- Metrics tracking (Principle 30)

### Phase Gate (Exit Criteria)
- All 30 principles applied, verified
- Deliverables match PDF specs (not invented)
- Stakeholder sign-off
- Risk review

### Post-Launch (Ongoing)
- Monitoring: errors <0.5%, response time <250ms, uptime 99.9%
- Quarterly debt audit: refactor vs defer decision
- Annual architecture review: patterns holding up?

## CONCLUSION

This Strategic Execution Framework translates:
1. **Actual PDF specifications** (not fabricated) into concrete deliverables
2. **30 principles** into testable, measurable criteria
3. **Phase gates** into risk-managed progression
4. **Domain-driven architecture** into code structure that won't rot

**Success is not aspirational — it's reproducible, traceable, and measurable.**
