+# Phase 7 Plan 01: MockAgentManager Adapter Summary
+
+**MockAgentManager adapter implementing AgentManager port with configurable scenarios (success, crash, waiting_for_input) for E2E test isolation**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-31T07:40:58Z
+- **Completed:** 2026-01-31T07:43:18Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+
+- MockAgentManager class implementing full AgentManager port interface
+- MockAgentScenario interface for configuring agent behavior (outcome, delay, message, filesModified, question)
+- setScenario() for per-agent scenario overrides
+- All lifecycle events emitted: agent:spawned, agent:stopped, agent:crashed, agent:waiting, agent:resumed
+- Comprehensive test suite with 28 test cases
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Implement MockAgentManager adapter** - `6148af7` (feat)
+2. **Task 2: Write comprehensive tests for MockAgentManager** - `e305375` (test)
+
+## Files Created/Modified
+
+- `src/agent/mock-manager.ts` - MockAgentManager adapter with scenario configuration
+- `src/agent/mock-manager.test.ts` - 28 comprehensive tests covering all scenarios
+- `src/agent/index.ts` - Export MockAgentManager and MockAgentScenario
+
+## Decisions Made
+
+- **In-memory Map for agent storage:** No database needed for mock adapter - tests don't need persistence
+- **setTimeout for async completion:** Even with delay=0, completion happens via setTimeout for consistent async behavior in tests
+- **Resume completes successfully by default:** After resume, agents complete with success to simplify test scenarios (can be overridden if needed)
+- **clear() method for test cleanup:** Allows tests to reset state between runs
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- MockAgentManager ready for use in E2E tests
+- Can be injected in place of ClaudeAgentManager via dependency injection
+- All scenario types proven working: success, crash, waiting_for_input
+- Event emission verified for integration with dispatch/coordination testing
