# Implementation Report — EPIC-004 / web-kingston

## Status

- [x] Domain: StructureMaterialRepository.ts interface
- [x] Use Cases: 4 use cases (Get, Create, Update, Delete)
- [x] Infrastructure: Response types, Mapper, API Repository
- [x] DI Wiring: types.ts and container.ts
- [x] Form: StructureMaterialFormValues.ts schema
- [x] Hooks: useGetStructureMaterials, useStructureMaterialActions
- [x] Components: StructureMaterialTable, StructureMaterialFormModal
- [x] Page: DetailProductStructureMaterials
- [x] Layout: DetailProductStructureLayout + allRoutes
- [ ] Testing: Smoke test in browser

## Files to Create/Modify

## Progress Notes

### 2026-05-21: Domain + Application + Infrastructure Complete

Successfully implemented all core layers:

**Domain Layer:**
- `StructureMaterialRepository.ts` — repository interface with 4 methods
- Supports assembly qty and packaging qty for material assignments

**Application Layer:**
- 4 use cases for CRUD operations
- Each injected with repository dependency
- Clean separation of concerns

**Infrastructure Layer:**
- `StructureMaterialApiRepository.ts` — API consumer implementation
- `StructureMaterialResponse.ts` — API response types
- `StructureMaterialMapper.ts` — domain mapper
- Uses `/api/admin/structures/:id/materials` endpoint

**DI & Container:**
- Added 5 symbols to types.ts (repo + 4 use cases)
- Registered all bindings in container.ts
- Uses existing TYPES.ApiService for HTTP

**Presentation Layer:**
- Form schema with yup validation
- 2 hooks: useGetStructureMaterials (fetch) + useStructureMaterialActions (mutations)
- Table component with edit/delete actions
- Modal form with assembly qty / packaging qty inputs
- Detail page with permission checks

**Routing:**
- Added Materials tab to DetailProductStructureLayout
- Route `/structures/:id/materials` → DetailProductStructureMaterials
- Integrated with existing structure layout

All 20 files created successfully. Architecture follows Clean Architecture patterns consistent with existing modules (ProductStructure, Material, etc.).
