# Phase 11 Plan 08: TestHarness Helpers & Architect E2E Tests Summary

**Added TestHarness architect mode support and comprehensive E2E tests for the complete architect workflow**

## Performance

- **Duration:** 4 min
- **Started:** 2026-01-31T19:25:00Z
- **Completed:** 2026-01-31T19:29:00Z
- **Tasks:** 3
- **Files modified:** 4

## Accomplishments

- Enhanced TestHarness with tRPC caller and initiative/phase repositories
- Added architect-specific scenario helpers (setArchitectDiscussComplete, setArchitectBreakdownComplete)
- Added convenience helpers (mockAgentManager alias, advanceTimers, getEmittedEvents)
- Created comprehensive E2E tests for discuss mode (completion, Q&A flow)
- Created E2E tests for breakdown mode and phase persistence
- Added full workflow test covering discuss -> breakdown -> phases

## Task Commits

Each task was committed atomically:

1. **Task 1: Add TestHarness helpers for architect modes** - `021937c` (feat)
2. **Task 2: Add E2E test for discuss mode** - `ae130e9` (test)
3. **Task 3: Add E2E test for breakdown mode and phase persistence** - `47b4623` (test)

## Files Created/Modified

- `src/test/harness.ts` - Added tRPC caller, repositories, architect helpers
- `src/test/index.ts` - Export TRPCCaller type
- `src/test/e2e/architect-workflow.test.ts` - New E2E test file (5 tests)
- `src/agent/mock-manager.test.ts` - Fixed pre-existing test issues

## Tests Added

- **Discuss mode completion** - Spawn architect, complete with decisions
- **Discuss Q&A flow** - Pause on questions, resume with answers
- **Breakdown mode completion** - Spawn architect, complete with phases
- **Phase persistence** - Create and retrieve phases from breakdown
- **Full workflow** - Discuss -> Breakdown -> Phase persistence

## Decisions Made

1. **TestHarness tRPC caller** - Enables direct procedure invocation in tests
2. **Architect scenario helpers** - Convenience wrappers for context_complete, breakdown_complete
3. **Full workflow coverage** - Single test proving entire architect flow works

## Deviations from Plan

Minor fixes to pre-existing test issues (dependencies in PhaseBreakdown, type casting for AgentStoppedEvent).

## Issues Encountered

None

## User Setup Required

None - tests run automatically.

## Phase 11 Completion

This was the final plan in Phase 11 (Architect Agent). Phase 11 is now complete:
- 11-01: Agent mode and schema updates
- 11-02: Discuss and breakdown mode output schemas
- 11-03: Mode-aware agent manager implementation
- 11-04: Initiative and phase tRPC procedures
- 11-05: Agent prompts module and architect spawn procedures
- 11-06: Initiative and architect CLI commands
- 11-07: Unit tests for modes and repositories
- 11-08: TestHarness helpers and E2E tests (this plan)

## Next Phase Readiness

- Phase 11 complete - architect workflow fully tested
- Ready for Phase 12 (if exists) or milestone completion
