docs(architecture): add OMS·WMS·ERP commercialization WBS as Phase 12 foundation

- Complete 1,600-line WBS (spec/60_oms_wms_erp_wbs.yaml) with 12 phases
- 18-week timeline, 13-person team, $371K budget
- Strategic principles: SOLID, data consistency, parsimony, zero hallucination
- Quantified success metrics (70%+ test coverage, Lighthouse 90+, 99.9% uptime)
- Phase breakdown: Requirements → Development → Testing → Deployment → Stabilization
- Phase 0 (Week 1-2): Baseline establishment, FRD, OpenAPI spec, wireframes
- Phase 1-11: Progressive build-out of 4-layer components + 11 CRUD templates
- Gated by QuantEngine Phase 2 completion (KIS API production validation)
- 30-year senior architect perspective: architecture, PM, PL, dev, UX, QA, ops

Alignment with QuantEngine roadmap: Phase 12 (OMS·WMS·ERP) follows Phase 5 (Admin UI).

+## OMS·WMS·ERP Commercialization Project WBS (2026-07-26)
+
+**OFFICIAL PROJECT FOUNDATION** — 30-Year Senior Architect/PM/PL/Dev/UX/QA/User Perspective
+
+### Strategic Vision
+
+**Objective**: Enterprise-grade Order Management (OMS) + Warehouse Management (WMS) + Enterprise Resource Planning (ERP) platform commercialization with:
+- 4-layer input components (Primitive/Composite/Smart/Domain Templates)
+- 11 standard CRUD templates (fully normalized data model)
+- Vue 3 + TypeScript modern stack
+- SOLID principles, data consistency, process simplification
+- 100% test-driven, zero hallucination, full traceability
+
+**Duration**: 18 weeks (4.5 months, 12 phases)  
+**Team**: 13 FTE (PM, PL, 4 FE devs, 1 UX, 2 QA, 1 DevOps, 0.5 security, 0.5 docs)  
+**Budget**: $371K USD (infrastructure, tooling, salaries)  
+**Target Launch**: Q4 2026
+
+### Core Principles (Engineering Foundation)
+
+| Principle | Application | Success Metric |
+|-----------|-------------|-----------------|
+| **SOLID** | Single Responsibility, Open/Closed, Liskov, Interface Segregation, Dependency Inversion | TypeScript strict mode, component test coverage 70%+ |
+| **Data Consistency** | PostgreSQL SSOT, audit trails, 3NF normalization | Zero data anomalies, complete audit log |
+| **Parsimony** | No gold-plating, hypothesis-driven, necessity-based features | Feature scope fixed per phase, 0 scope creep |
+| **Normalization** | 3NF minimum, denormalization only after performance proof | Schema review, query analysis |
+| **Process Simplification** | Automate after validation, reduce cognitive load | Automated CI/CD, runbooks for ops |
+| **Patterns & Standardization** | Consistent naming, API contracts, component interfaces | Code review checklist, lint/format automation |
+| **Structuring** | Layered architecture, modularity, microfront-end expansion path reserved | 4-layer components, clear responsibilities |
+| **Vibes Coding** | Clear naming, minimal cognitive overhead, consistency | Pair programming, weekly code reviews |
+| **Hallucination Prevention** | Test-driven, contract validation, schema enforcement | All features backed by tests, no assumptions |
+| **Ground Truth & Traceability** | 100% reproducible (deterministic inputs), full history | Git commit history, audit logs, runbook documentation |
+| **Reliability** | Graceful degradation, fault isolation, auto-recovery | Blue-green deployment, automatic rollback, 99.9% uptime |
+| **Componentization** | Smart/Dumb separation, reusability | npm package @quantengine/ui, Storybook coverage |
+| **Technical Debt** | Zero new debt, reduce existing by 50% per half-year | Quarterly debt audit, refactoring sprints |
+
