Extend PlanRepository with methods needed for task decomposition workflow.

Purpose: Enable creating plans from architect output and querying plans by phase. The decompose agent needs to know what plans exist in a phase to break them into tasks.

Output: PlanRepository with findByPhaseId, getNextNumber, bulk creation methods.

Task 1: Extend PlanRepository port interface src/db/repositories/plan-repository.ts Add the following methods to PlanRepository interface (following pattern from PhaseRepository):

1. findByPhaseId(phaseId: string): Promise<Plan[]> - Get all plans for a phase, ordered by number
2. getNextNumber(phaseId: string): Promise<number> - Get next available plan number (MAX+1 or 1 if none) npm run build passes (no implementation yet) PlanRepository interface extended with new methods

Task 2: Implement methods in DrizzlePlanRepository src/db/repositories/drizzle/drizzle-plan-repository.ts Implement the new methods in DrizzlePlanRepository adapter:

1. findByPhaseId(phaseId):

   • Query plans table where phase_id = phaseId
   • Order by number ascending
   • Return array (empty if none)

2. getNextNumber(phaseId):

   • Query MAX(number) where phase_id = phaseId
   • Return max + 1, or 1 if no plans exist

Follow the pattern from DrizzlePhaseRepository.getNextNumber. npm run build passes, npm test passes DrizzlePlanRepository implements findByPhaseId and getNextNumber

Task 3: Export types from repositories index src/db/repositories/index.ts Verify PlanRepository and its types are properly exported. If not already exported: - Export PlanRepository interface - Export CreatePlanData type - Export UpdatePlanData type

Check existing exports and add if missing. npm run build passes, types importable from src/db/repositories All PlanRepository types properly exported

Before declaring plan complete: - [ ] npm run build succeeds - [ ] npm test passes all tests - [ ] PlanRepository.findByPhaseId exists and works - [ ] PlanRepository.getNextNumber exists and works - [ ] Types exported from index

<success_criteria>

• All tasks completed
• All verification checks pass
• No errors or warnings introduced
• PlanRepository ready for tRPC procedures </success_criteria>

After completion, create `.planning/phases/12-phase-task-decomposition/12-02-SUMMARY.md`
