## Test Commands

### T09 Coverage Suite
```bash
cd /a0/usr/workdir/dev-projects/leocrm && python -m pytest tests/test_ai_copilot.py tests/test_workflows.py --cov=app.ai --cov=app.workflows --cov=app.services.ai_copilot_service --cov=app.services.workflow_service --cov=app.routes.ai_copilot --cov=app.routes.workflows --cov-report=term-missing --tb=short -v
```
**Result**: 135 passed, coverage 84.12%

### Full Regression
```bash
cd /a0/usr/workdir/dev-projects/leocrm && python -m pytest tests/ -v --tb=short
```
**Result**: 238 passed, 0 failed, 2 warnings (pre-existing deprecation warning)

## Smoke Test
- T09 coverage suite: 135/135 tests pass
- Full regression: 238/238 tests pass (133 existing + 105 new)
- No production code modified — only test files updated
- All 22 original ACs still pass
