Two pieces of the previous design remained behind and were breaking CI: 1. ``m3_001_invariants_table`` still issued ``op.create_table('invariants', ...)`` for the obsolete column set. When the upgrade chain reached ``m11_001_standalone_invariants`` the same table was created a second time, raising ``OperationalError: table invariants already exists`` in ``before_scenario`` for every behave + robot scenario that initialises the test database. That is the root cause of the 119 ``errored`` scenarios in the CI ``unit_tests`` job and the integration_tests collapse on PR #8684. Turn ``m3_001`` into a no-op ``upgrade``/``downgrade`` so the historical revision id stays reachable by the downstream merge migrations (``m3_002_merge_invariants_and_a5_006`` and ``m9_004_merge_invariants_branch``) without touching the new schema that ``m11_001`` now owns. 2. ``robot/invariant_model.robot`` + ``robot/helper_invariant_model.py`` and ``features/invariant_model.feature`` + ``features/steps/invariant_model_steps.py`` were smoke-tests written for the removed legacy schema (``description``, ``is_active``, UUID ids). They instantiate ``InvariantModel(description=..., is_active=...)`` and assert an ``ix_invariants_is_active`` index that the new schema does not have, so every scenario in the suite fails with ``TypeError: 'description' is an invalid keyword argument``. The real persistence contract is already covered by ``features/tdd_invariant_persistence.feature``, ``robot/tdd_invariant_persistence.robot`` and ``robot/invariant_cli.robot`` against the current schema; the legacy-schema fixtures have no remaining users (verified via ``grep -rn helper_invariant_model``). Delete them. Also runs ``ruff format`` on ``models.py`` to drop a trailing blank line that was tripping the ``format`` nox session in CI ``lint``. Verified locally: * ``ruff format --check .`` -> 2298 files already formatted. * ``ruff check src/ scripts/ examples/ features/ robot/ .opencode/`` -> All checks passed. * ``nox -s unit_tests-3.13 -- features/tdd_invariant_persistence.feature`` -> 4 scenarios passed, 0 failed, 0 errored. * ``nox -s integration_tests-3.13 -- robot/tdd_invariant_persistence.robot robot/invariant_cli.robot robot/`` -> only the 8 deleted ``Suites.Robot.Invariant Model`` cases failed; deleting the suite removes them entirely.
