## Specification Compliance Guidelines

### How to Ensure Specification Adherence

1. **Before Each Phase**: Complete the Pre-Implementation Specification Gate
2. **During Implementation**: Reference specific SDD sections in each task
3. **After Each Task**: Run Specification Compliance checks
4. **Phase Completion**: Verify all specification requirements are met

### Deviation Protocol

If implementation cannot follow specification exactly:
1. Document the deviation and reason
2. Get approval before proceeding
3. Update SDD if the deviation is an improvement
4. Never deviate without documentation

## Metadata Reference

- `[parallel: true]` - Tasks that can run concurrently
- `[component: component-name]` - For multi-component features
- `[ref: document/section]` - Links to specifications, patterns, or interfaces (avoid fragile line references)
- `[activity: type]` - Activity hint for specialist agent selection

---

## Context Priming

*GATE: You MUST fully read all files mentioned in this section before starting any implementation.*

**Specification**:

- `docs/specs/018-store-configuration/product-requirements.md` - Product Requirements (all validation checks passed)
- `docs/specs/018-store-configuration/solution-design.md` - Solution Design (architecture confirmed)

**Key Design Decisions**:

- **ADR-1**: Store hours in central database (`kiosk_buykiosk`) - single source of truth
- **ADR-2**: Separate tables for per-day (`storeOperatingHours`) and holiday (`storeHolidayHours`) hours
- **ADR-3**: Add a new Store Configuration page at `/admin/:typeNum/store/configuration` and add a sidebar link (do not overwrite the existing store password/settings page without an explicit deprecation decision)
- **ADR-4**: Wall-clock time format (HH:MM VARCHAR(5)), not UTC timestamps
- **ADR-5**: Same-day hours only (no overnight support) - close time must be > open time

**Implementation Context**:

- Commands to run:
  - `./test.sh` - Run all tests
  - `./test.sh --testsuite unit` - Run unit tests only
  - `./test.sh --stan` - Run tests + PHPStan analysis
  - `php userfrosting/conductor run` - Run database migrations
  - `php userfrosting/conductor build-css --minify` - Build CSS for production
- Patterns to follow:
  - `userfrosting/src/BuyerKiosk/Scheduling/Controllers/SchedulingController.php` - API controller pattern
  - `userfrosting/src/BuyerKiosk/Scheduling/Controllers/SchedulingPageController.php` - Page controller pattern
  - `userfrosting/src/BuyerKiosk/Scheduling/Repositories/` - Repository pattern
  - `userfrosting/templates/themes/default/scheduling/settings.html` - Admin settings template pattern
- Interfaces to implement:
  - `GET /api/:typeNum/store/config` - Get store configuration `[ref: SDD/Interface Specifications]`
  - `PUT /api/:typeNum/store/hours` - Update store hours `[ref: SDD/Interface Specifications]`
  - `POST/PUT/DELETE /api/:typeNum/store/holidays` - Manage holiday hours `[ref: SDD/Interface Specifications]`

## Phase Dependencies

```
T1 (Database Schema)
    ↓
T2 (Repository & Service)
    ↓
T3 (API Endpoints)
    ↓
T4 (Admin UI) ←→ T5 (Calendar Integration) [parallel after T3]
    ↓              ↓
    └──────┬───────┘
           ↓
T6 (Integration & E2E Validation)
```

**Critical Path**: T1 → T2 → T3 → T6

**Parallel Opportunities**:
- T2.2 (StoreHoursRepository) and T2.3 (StoreHolidayRepository) can run in parallel
- T4 (Admin UI) and T5 (Calendar Integration) can run in parallel after T3 completes
- T4.4 (Template) and T4.5 (JavaScript) can run in parallel
