feat(01-foundation-01): Alembic migrations with RLS and tenant isolation tests
- alembic.ini + migrations/env.py: async SQLAlchemy migration setup using asyncpg
- migrations/versions/001_initial_schema.py: creates tenants, agents, channel_connections, portal_users
- ENABLE + FORCE ROW LEVEL SECURITY on agents and channel_connections
- RLS policy: tenant_id = current_setting('app.current_tenant', TRUE)::uuid
- konstruct_app role created with SELECT/INSERT/UPDATE/DELETE on all tables
- packages/shared/shared/rls.py: idempotent configure_rls_hook, UUID-sanitized SET LOCAL
- tests/conftest.py: test_db_name (session-scoped), db_engine + db_session as konstruct_app
- tests/unit/test_normalize.py: 11 tests for KonstructMessage Slack normalization (CHAN-01)
- tests/unit/test_tenant_resolution.py: 7 tests for workspace_id → tenant resolution (TNNT-02)
- tests/unit/test_redis_namespacing.py: 15 tests for Redis key namespace isolation (TNNT-03)
- tests/integration/test_tenant_isolation.py: 7 tests proving RLS tenant isolation (TNNT-01)
- tenant_b cannot see tenant_a's agents or channel_connections
- FORCE ROW LEVEL SECURITY verified via pg_class.relforcerowsecurity

Shared test fixtures for Konstruct.
|
||||
|
||||
IMPORTANT: The `db_session` fixture connects as `konstruct_app` (not postgres
|
||||
superuser). This is mandatory — RLS is bypassed for superuser connections, so
|
||||
tests using superuser would pass trivially while providing zero real protection.
|
||||
|
||||
Integration tests requiring a live PostgreSQL container are skipped if the
|
||||
database is not available. Unit tests never require a live DB.
|
||||
|
||||
Event loop design: All async fixtures use function scope to avoid pytest-asyncio
|
||||
cross-loop-scope issues. The test database is created once (at session scope, via
|
||||
a synchronous fixture) and reused across tests within the session.
