+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-01-31T16:52:52Z
+- **Completed:** 2026-01-31T16:57:38Z
+- **Tasks:** 3
+- **Files modified:** 10
+
+## Accomplishments
+
+- Changed agent output schema status from 'question' to 'questions' (plural)
+- Added QuestionItem type with unique id field for answer correlation
+- Updated PendingQuestions interface to wrap questions array
+- Updated AgentWaitingEvent payload to use questions array
+- Updated all adapters (ClaudeAgentManager, MockAgentManager) and test infrastructure
+
+## Task Commits
+
+All three tasks were committed atomically since they're interdependent:
+
+1. **Task 1: Update agent output schema** - `151a4c9` (feat)
+2. **Task 2: Update PendingQuestion type** - `151a4c9` (feat)
+3. **Task 3: Update AgentWaitingEvent payload** - `151a4c9` (feat)
+
+_Note: Single atomic commit because schema/type/event changes require downstream adapter updates to compile_
+
+## Files Created/Modified
+
+- `src/agent/schema.ts` - Added questionItemSchema, changed status to 'questions'
+- `src/agent/types.ts` - Added QuestionItem, renamed PendingQuestion to PendingQuestions
+- `src/events/types.ts` - Updated AgentWaitingEvent payload to questions array
+- `src/agent/manager.ts` - Updated ClaudeAgentManager for new schema
+- `src/agent/mock-manager.ts` - Updated MockAgentManager and MockAgentScenario
+- `src/test/harness.ts` - Renamed setAgentQuestion to setAgentQuestions
+- `src/agent/mock-manager.test.ts` - Updated test scenarios
+- `src/dispatch/manager.test.ts` - Updated mock interface
+- `src/test/e2e/edge-cases.test.ts` - Updated test scenarios
+- `src/test/e2e/recovery-scenarios.test.ts` - Updated test scenarios
+
+## Decisions Made
+
+| Decision | Rationale |
+|----------|-----------|
+| Status 'questions' (plural) | Clearer than 'question' when payload is array |
+| Each question has id field | Enables matching answers to specific questions in batched resume |
+| Single question uses array | Consistent API - single question is `questions: [{ id: 'q1', question: '...' }]` |
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Updated downstream adapters and tests**
+- **Found during:** Task 1 (Schema changes)
+- **Issue:** Schema changes broke type compilation in adapters and tests
+- **Fix:** Updated ClaudeAgentManager, MockAgentManager, TestHarness, and all test files
+- **Files modified:** manager.ts, mock-manager.ts, harness.ts, 4 test files
+- **Verification:** npm run build passes, npm test passes (381 tests)
+- **Committed in:** 151a4c9 (combined with schema changes)
+
+---
+
+**Total deviations:** 1 auto-fixed (blocking issue)
+**Impact on plan:** Necessary downstream updates for type safety. No scope creep.
+
+## Issues Encountered
+
+None - plan executed with expected downstream cascading updates.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Multi-question schema complete, ready for Phase 11 (Architect Agent)
+- Schema supports batching multiple questions in single pause
+- Tests verify full question lifecycle with new array structure
