Phase 2 will add a NOT NULL migration after users and auth are live. The nullable column allows existing single-user documents to be migrated without a user FK. +- **`groups` table as v2 stub** — Per D-02, the table is created now for schema completeness so future migrations don't need to alter dependency ordering. No rows are inserted in Phase 1. +- **SEQUENCES grants added** — The plan's privilege section specified table grants but not sequence grants. Since `audit_log.id` is an integer autoincrement (uses a PostgreSQL sequence), `docuvault_app` would fail on INSERT without SEQUENCES grants. Added as Rule 2 (missing critical functionality). +- **`config.set_main_option("sqlalchemy.url", os.environ.get(...))` in env.py** — `%(DATABASE_MIGRATE_URL)s` interpolation in `alembic.ini` only reads from `[alembic]` section variables, not OS env.
