+# Phase 11 Plan 07: Unit Tests for Modes & Repositories Summary
+
+**Added unit tests for MockAgentManager mode functionality and repository query methods**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-31T19:23:00Z
+- **Completed:** 2026-01-31T19:25:00Z
+- **Tasks:** 3
+- **Files modified:** 3
+
+## Accomplishments
+
+- Added MockAgentManager tests for execute/discuss/breakdown modes
+- Added tests verifying stopped event reasons (context_complete, breakdown_complete)
+- Added InitiativeRepository findByStatus tests for filtering by status
+- Added PhaseRepository findByNumber and getNextNumber tests including edge cases
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add MockAgentManager mode tests** - `567d863` (test)
+2. **Task 2: Add InitiativeRepository findByStatus tests** - `de57c15` (test)
+3. **Task 3: Add PhaseRepository findByNumber and getNextNumber tests** - `1f4a95d` (test)
+
+## Files Created/Modified
+
+- `src/agent/mock-manager.test.ts` - Added 'agent modes' describe block with 5 tests
+- `src/db/repositories/drizzle/initiative.test.ts` - Added 'findByStatus' describe block with 2 tests
+- `src/db/repositories/drizzle/phase.test.ts` - Added 'findByNumber' and 'getNextNumber' describe blocks with 6 tests total
+
+## Test Coverage Added
+
+| File | Tests Added | Total Tests |
+|------|-------------|-------------|
+| mock-manager.test.ts | 5 | 39 |
+| initiative.test.ts | 2 | 12 |
+| phase.test.ts | 6 | 16 |
+
+## Decisions Made
+
+None - plan executed exactly as specified.
+
+## Deviations from Plan
+
+### Adjustments
+
+**1. Tests already organized in existing files**
+- Plan referenced creating new test files, but tests were added to existing test files in `src/db/repositories/drizzle/`
+- This follows the existing codebase pattern and avoids duplication
+
+**Total deviations:** 1 (file location adjustment)
+**Impact on plan:** Positive - follows existing patterns
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All mode tests in place for E2E testing in 11-08
+- Repository methods fully tested
+- Test count: 397 passing
