# Dependency graph
|
|
requires:
|
|
- phase: 01-foundation/01-02
|
|
provides: SQLAlchemy models (Project, Discussion, Round, Message, Consensus)
|
|
provides:
|
|
- Async database session management (init_db, create_tables, get_session, close_db)
|
|
- In-memory database testing pattern
|
|
- Model test coverage (5 tests)
|

# Phase 01-03: Database & Tests Summary
|
|
|
|
**Async SQLAlchemy session management with in-memory test fixture and 5 model tests at 95% coverage**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 4 min
|
|
- **Started:** 2026-01-16T15:13:19Z
|
|
- **Completed:** 2026-01-16T15:17:06Z
|
|
- **Tasks:** 3 (2 with commits, 1 verification-only)
|
|
- **Files modified:** 2
|
|
|
|
## Accomplishments
|
|
- Created database.py with async session factory and context manager
|
|
- Implemented 5 comprehensive model tests covering creation, relationships, and cascades
|
|
- Achieved 95% code coverage on core module
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create database module** - `bb932e6` (feat)
|
|
2. **Task 2: Create model tests** - `fb81fea` (test)
|
|
3. **Task 3: Verify gitignore and test suite** - No commit needed (entries already present)
|
|
|
|
## Files Created/Modified
|
|
- `src/moai/core/database.py` - Async session management with init_db, create_tables, get_session, close_db
|
|
- `tests/test_models.py` - 5 tests: create_project, create_discussion_with_project, create_full_discussion_chain, create_consensus, project_cascade_delete
|
|
|
|
## Decisions Made
|
|
- Used `expire_on_commit=False` in session factory to allow attribute access after commit without re-query
|
|
- Session context manager handles commit/rollback automatically
|
|
- Module-level globals for engine/factory simplifies dependency injection for this Phase 1 scope
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
**Note:** Task 3 required no commit because `.gitignore` already contained all specified entries from a previous setup phase.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## Test Results
|
|
|
|
```

|
tests/test_models.py::test_create_project PASSED

|
tests/test_models.py::test_create_discussion_with_project PASSED
|

tests/test_models.py::test_project_cascade_delete PASSED
|
|
|
|
Coverage: 95% (101 statements, 5 missing)
|
|
Missing: error handling paths in database.py (lines 62, 85, 91-93)
|
|
```
|
|
|
|
## Next Phase Readiness
|
|
- Foundation phase complete: scaffolding, models, database all working
|
|
- Ready for Phase 2: Bot Core (handlers, middleware, bot setup)
|
|
- All core infrastructure tested and operational
