+# Phase 11 Plan 04: Initiative & Phase tRPC Procedures Summary
+
+**Added tRPC procedures for Initiative and Phase CRUD operations with bulk phase creation for Architect breakdown output**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-01-31T19:10:00Z
+- **Completed:** 2026-01-31T19:13:00Z
+- **Tasks:** 3
+- **Files modified:** 2
+
+## Accomplishments
+
+- Added InitiativeRepository and PhaseRepository to tRPC context with optional injection
+- Implemented Initiative CRUD procedures: createInitiative, listInitiatives, getInitiative, updateInitiative
+- Implemented Phase CRUD procedures: createPhase, listPhases, getPhase, updatePhase
+- Added createPhasesFromBreakdown for bulk phase creation from Architect agent output
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add repositories to tRPC context** - `3bf7e2c` (feat)
+2. **Task 2: Add Initiative tRPC procedures** - `4d42da9` (feat)
+3. **Task 3: Add Phase tRPC procedures** - `d865330` (feat)
+
+## Files Created/Modified
+
+- `src/trpc/context.ts` - Added InitiativeRepository and PhaseRepository types to context
+- `src/trpc/router.ts` - Added 9 new tRPC procedures for Initiative and Phase CRUD
+
+## Decisions Made
+
+1. **Repositories optional in context** - Following existing pattern used by agentManager, taskRepository, etc. for backwards compatibility
+2. **createPhasesFromBreakdown accepts pre-numbered phases** - Architect breakdown output includes phase numbers, so bulk create accepts them directly rather than auto-generating
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Initiative and Phase CRUD available via tRPC
+- Ready for 11-05-PLAN.md (Architect Spawn Procedures)
