Summary

Add Behave BDD and Robot Framework integration tests that capture bug #1022 — InvariantService stores invariants in an in-memory dict only, losing them across CLI process invocations.

Motivation

Per the project's TDD Bug Fix Workflow (CONTRIBUTING.md), every bug must first have a test written that captures the buggy behavior before the fix is implemented. This PR fulfills the TDD counterpart issue #1032 for bug #1022.

What was done

Behave tests (features/tdd_invariant_persistence.feature): Four scenarios tagged @tdd_expected_fail @tdd_bug @tdd_bug_1022 @mock_only that simulate separate CLI invocations via fresh InvariantService instances and assert cross-instance data visibility:

1. Project invariant persistence across service instances
2. Global invariant persistence across service instances
3. CLI add/list across separate invocations
4. Cross-instance soft-delete by invariant ID

Step definitions in features/steps/tdd_invariant_persistence_steps.py.

Robot integration tests (robot/tdd_invariant_persistence.robot): Three integration test cases with a helper script (robot/helper_tdd_invariant_persistence.py) that exercises add-then-list and add-then-remove across fresh service instances.

How it passes CI

All tests carry @tdd_expected_fail, which inverts the test result via the environment hooks (Behave) and listener (Robot). The underlying assertions fail (proving the bug exists), but are reported as passed to CI. The @tdd_expected_fail tag will be removed when bug #1022 is fixed, at which point the tests will run normally and must pass.

Review fixes applied

• M1: Moved InvariantScope import from function body in robot/helper_tdd_invariant_persistence.py to module-level top imports.
• m1: Added @mock_only tag to features/tdd_invariant_persistence.feature — these tests use purely in-memory services and never touch the database.
• m2: Added exit_code == 0 assertion to step_invoke_list_cli in features/steps/tdd_invariant_persistence_steps.py, matching the pattern used in step_invoke_add_cli.
• m3: Changed all context: Any parameter types to context: Context (from behave.runner), following the project-wide convention used in 335+ step files.
• m4: Narrowed except Exception to except NotFoundError in robot/helper_tdd_invariant_persistence.py, matching the specific error being tested.
• n3: Branch rebased onto latest master.

Quality Gates

• lint: ✅ passed
• typecheck: ✅ passed (Pyright, 0 errors)
• unit_tests: ✅ 1 feature, 4 scenarios, 16 steps — all passed via @tdd_expected_fail
• coverage: ≥ 97% (test-only changes, no source modifications)

Closes #1032

Review: APPROVED

Exemplary TDD bug-capture PR. This is the most comprehensive TDD PR in the batch:

• Dual framework coverage: Both Behave BDD scenarios and Robot Framework integration tests
• Tag compliance: @tdd_expected_fail @tdd_bug @tdd_bug_1022 correct in both frameworks
• Branch naming: tdd/m5-invariant-service-persistence correctly matches M5 (v3.4.0)
• File organization: Proper — features in features/, steps in features/steps/, Robot files in robot/
• Step file naming: tdd_invariant_persistence_steps.py matches the feature file
• No production code changes: Only test files added
• Issue reference: Closes #1032 present
• PR description: Thorough — covers both test frameworks, motivation, and quality gates

Well-structured Robot helper script with clear dispatch pattern. No issues found.
