-## Development
-
-### Running Tests
-
-Basic Memory supports dual database backends (SQLite and Postgres). Tests are parametrized to run against both backends automatically.
-
-**Quick Start:**
-```bash
-# Run SQLite tests (default, no Docker needed)
-just test-sqlite
-
-# Run Postgres tests (requires Docker)
-just test-postgres
-```
-
-**Available Test Commands:**
-
- `just test-sqlite` - Run tests against SQLite only (fastest, no Docker needed)
- `just test-postgres` - Run tests against Postgres only (requires Docker)
- `just test-windows` - Run Windows-specific tests (auto-skips on other platforms)
- `just test-benchmark` - Run performance benchmark tests
- `just test-all` - Run all tests including Windows, Postgres, and benchmarks
-
-**Postgres Testing Requirements:**
-
-To run Postgres tests, you need to start the test database:
-```bash
-docker-compose -f docker-compose-postgres.yml up -d
-```
-
-Tests will connect to `localhost:5433/basic_memory_test`.
-
-**Test Markers:**
-
-Tests use pytest markers for selective execution:
- `postgres` - Tests that run against Postgres backend
- `windows` - Windows-specific database optimizations
- `benchmark` - Performance tests (excluded from default runs)
-
-**Other Development Commands:**
-```bash
-just install          # Install with dev dependencies
-just lint             # Run linting checks
-just typecheck        # Run type checking
-just format           # Format code with ruff
-just check            # Run all quality checks
-just migration "msg"  # Create database migration
-```
-
-See the [justfile](justfile) for the complete list of development commands.

+
+### Version 0.15.0 Changes
+
+**Breaking Change: Stateless Architecture**
+- All MCP tools now require explicit `project` parameter
+- No implicit project context carried between calls
+- Exception: `default_project_mode` config option enables fallback
+
+**Three-Tier Project Resolution**:
+1. CLI constraint: `--project name` flag (highest priority)
+2. Explicit parameter: `project="name"` in tool calls
+3. Default mode: `default_project_mode=true` in config (fallback)
+
+**Why This Matters**:
+- More predictable behavior across sessions
+- Explicit project selection prevents errors
+- Multi-project workflows more reliable
+- Single-project users can enable default mode for convenience

-# Dual-Backend Testing
-
-Basic Memory tests run against both SQLite and Postgres backends to ensure compatibility.
-
-## Quick Start
-
-```bash
-# Run tests against SQLite only (default, no setup needed)
-pytest
-
-# Run tests against Postgres only (requires docker-compose)
-docker-compose -f docker-compose-postgres.yml up -d
-pytest -m postgres
-
-# Run tests against BOTH backends
-docker-compose -f docker-compose-postgres.yml up -d
-pytest --run-all-backends  # Not yet implemented - run both commands above
-```
-
-## How It Works
-
-### Parametrized Backend Fixture
-
-The `db_backend` fixture is parametrized to run tests against both `sqlite` and `postgres`:
-
-```python
-@pytest.fixture(
-    params=[
-        pytest.param("sqlite", id="sqlite"),
-        pytest.param("postgres", id="postgres", marks=pytest.mark.postgres),
-    ]
-)
-def db_backend(request) -> Literal["sqlite", "postgres"]:
-    return request.param
-```
-
-### Backend-Specific Engine Factories
-
-Each backend has its own engine factory implementation:
-
- **`sqlite_engine_factory`** - Uses in-memory SQLite (fast, isolated)
- **`postgres_engine_factory`** - Uses Postgres test database (realistic, requires Docker)
-
-The main `engine_factory` fixture delegates to the appropriate implementation based on `db_backend`.
-
-### Configuration
-
-The `app_config` fixture automatically configures the correct backend:
-
-```python
-# SQLite config
-database_backend = DatabaseBackend.SQLITE
-database_url = None  # Uses default SQLite path
-
-# Postgres config
-database_backend = DatabaseBackend.POSTGRES
-database_url = "postgresql+asyncpg://basic_memory_user:dev_password@localhost:5433/basic_memory_test"
-```
-
-## Running Postgres Tests
-
-### 1. Start Postgres Docker Container
-
-```bash
-docker-compose -f docker-compose-postgres.yml up -d
-```
-
-This starts:
- Postgres 17 on port **5433** (not 5432 to avoid conflicts)
- Test database: `basic_memory_test`
- Credentials: `basic_memory_user` / `dev_password`
-
-### 2. Run Postgres Tests
-
-```bash
-# Run only Postgres tests
-pytest -m postgres
-
-# Run specific test with Postgres
-pytest tests/test_entity_repository.py::test_create -m postgres
-
-# Skip Postgres tests (default behavior)
-pytest -m "not postgres"
-```
-
-### 3. Stop Docker Container
-
-```bash
-docker-compose -f docker-compose-postgres.yml down
-```
-
-## Test Isolation
-
-### SQLite Tests
- Each test gets a fresh in-memory database
- Automatic cleanup (database destroyed after test)
- No setup required
-
-### Postgres Tests
- Database is **cleaned before each test** (drop all tables, recreate)
- Tests share the same Postgres instance but get isolated schemas
- Requires Docker Compose to be running
-
-## Markers
-
- `postgres` - Marks tests that run against Postgres backend
- Use `-m postgres` to run only Postgres tests
- Use `-m "not postgres"` to skip Postgres tests (default)
-
-## CI Integration
-
-### GitHub Actions
-
-Use service containers for Postgres (no Docker Compose needed):
-
-```yaml
-jobs:
-  test:
-    runs-on: ubuntu-latest
-
-    # Postgres service container
-    services:
-      postgres:
-        image: postgres:17
-        env:
-          POSTGRES_DB: basic_memory_test
-          POSTGRES_USER: basic_memory_user
-          POSTGRES_PASSWORD: dev_password
-        ports:
-          - 5433:5432
-        options: >-
-          --health-cmd pg_isready
-          --health-interval 10s
-          --health-timeout 5s
-          --health-retries 5
-
-    steps:
-      - name: Run SQLite tests
-        run: pytest -m "not postgres"
-
-      - name: Run Postgres tests
-        run: pytest -m postgres
-```
-
-## Troubleshooting
-
-### Postgres tests fail with "connection refused"
-
-Make sure Docker Compose is running:
-```bash
-docker-compose -f docker-compose-postgres.yml ps
-docker-compose -f docker-compose-postgres.yml logs postgres
-```
-
-### Port 5433 already in use
-
-Either:
- Stop the conflicting service
- Change the port in `docker-compose-postgres.yml` and `tests/conftest.py`
-
-### Tests hang or timeout
-
-Check Postgres health:
-```bash
-docker-compose -f docker-compose-postgres.yml exec postgres pg_isready -U basic_memory_user
-```
-
-## Future Enhancements
-
- [ ] Add `--run-all-backends` CLI flag to run both backends in sequence
- [ ] Implement test fixtures for backend-specific features (e.g., Postgres full-text search vs SQLite FTS5)
- [ ] Add performance comparison benchmarks between backends

-1. When kebab_filenames=true: All special characters, spaces, periods, underscores,
-   and mixed case are converted to lowercase kebab-case
-2. When kebab_filenames=false: Original formatting is preserved (backward compatibility)
-3. Folder paths are not affected by kebab_filenames setting
-4. Permalinks are always kebab-case regardless of kebab_filenames setting
