# Dependency graph
requires:
  - phase: 02-data-layer
    provides: Repository pattern, Drizzle ORM setup
provides:
  - InitiativeRepository.findByStatus method
  - PhaseRepository.findByNumber method
  - PhaseRepository.getNextNumber method
affects: [11-architect-agent, phase-breakdown]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Query filtering with drizzle eq() for status lookup
    - Compound queries with drizzle and() for multi-column lookup
    - Aggregate queries with drizzle max() for sequence generation

key-files:
  created: []
  modified:
    - src/db/repositories/initiative-repository.ts
    - src/db/repositories/drizzle/initiative.ts
    - src/db/repositories/phase-repository.ts
    - src/db/repositories/drizzle/phase.ts

key-decisions:
  - "findByStatus returns array (not null) for consistency with findAll pattern"
  - "getNextNumber uses max() aggregate, returning 1 if no phases exist"

# Phase 11 Plan 02: Initiative & Phase Repositories Summary

**Extended InitiativeRepository with findByStatus and PhaseRepository with findByNumber/getNextNumber for Architect agent persistence needs**

## Performance

- **Duration:** 3 min
- **Started:** 2026-01-31T18:02:00Z
- **Completed:** 2026-01-31T18:05:55Z
- **Tasks:** 3
- **Files modified:** 4

## Accomplishments

- Added `findByStatus` method to InitiativeRepository for filtering initiatives by status
- Added `findByNumber` method to PhaseRepository for looking up phases by initiative and sequence number
- Added `getNextNumber` method to PhaseRepository for getting next available phase number
- All methods implemented in Drizzle adapters following existing patterns

## Task Commits

Each task was committed atomically:

1. **Task 1: Add findByStatus to InitiativeRepository** - `768c4d2` (feat)
2. **Task 2: Add findByNumber and getNextNumber to PhaseRepository** - `67cfd4d` (feat)
3. **Task 3: Verify exports** - No commit needed (exports already correct)

## Files Created/Modified

- `src/db/repositories/initiative-repository.ts` - Added findByStatus method signature
- `src/db/repositories/drizzle/initiative.ts` - Implemented findByStatus with eq() filter
- `src/db/repositories/phase-repository.ts` - Added findByNumber and getNextNumber signatures
- `src/db/repositories/drizzle/phase.ts` - Implemented both methods with and()/max() queries

## Decisions Made

1. **findByStatus returns array** - Consistent with findAll pattern, returns empty array if no matches
2. **getNextNumber uses max() aggregate** - Returns MAX(number) + 1, or 1 if no phases exist for initiative

## Deviations from Plan

### Auto-fixed Issues

Note: The plan specified creating files from scratch, but InitiativeRepository and PhaseRepository already existed from Phase 2. Extended existing implementations instead of creating new files.

**Total deviations:** 1 (scope adjustment - extended existing rather than creating new)
**Impact on plan:** No negative impact - result matches plan intent

## Issues Encountered

Pre-existing test failures unrelated to this plan were observed (agents table mode column migration issue). These failures existed before the plan execution and do not affect the repository functionality added in this plan.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- InitiativeRepository and PhaseRepository now have all methods needed for Architect agent
- Ready for 11-03-PLAN.md (ClaudeAgentManager Mode Support)
