From 300c00acd9aca3b51ee1ea04dcc6280bf4ebcdd9 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Fri, 8 May 2026 11:21:10 +0000 Subject: [PATCH 1/6] feat(invariants): implement Invariant data model and database schema Implement the Invariant SQLAlchemy ORM model in cleveragents.infrastructure.database.models.InvariantModel with fields id (UUID), description (text), created_at (timestamp), and is_active (bool). Added Alembic migration m3_001_invariants_table that creates the invariants table with an index on is_active for efficient active-invariant queries. Includes both upgrade and downgrade paths. BDD Behave unit tests cover invariant creation, persistence, filtering by is_active, deactivation, and schema validation. Robot Framework integration tests provide smoke testing of the implementation contract.

before creating PRs. Includes concrete examples for each subsection and compliance verification pseudocode. * HAL 9000 has contributed comprehensive milestone documentation for v3.6.0 (Advanced Concepts & Deferred Features) and v3.7.0 (TUI Implementation) (PR #9903): split into sub-documents covering context strategies, LLM backends, resource types, A2A rename, container tool execution, scope chain resolution, cost/safety budgets, E2E workflow tests, code review examples, plugin architecture, TUI layout, persona system, reference/command input, session management, configuration, and TuiMaterializer integration. * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch. * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files. * HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation. * HAL 9000 has contributed the Strategize phase full context snapshot fix (issue #9056): added `_build_strategize_context_snapshot()` helper to `PlanLifecycleService`, updated `_try_record_decision()` to accept and forward a `ContextSnapshot` parameter, and added BDD test coverage verifying all four `ContextSnapshot` fields (`hot_context_hash`, `hot_context_ref`, `actor_state_ref`, `relevant_resources`) are populated during the Strategize phase. * HAL 9000 has contributed the ACMS context path matching fix (PR #10975 / issue #10972): corrects `_path_matches()` and `_matches_pattern()` to properly match absolute fragment paths against relative glob patterns by auto-prefixing with `**/` before calling `PurePath.full_match()`, preventing silent inefficacy of include/exclude filters for absolute paths in fragment metadata. -* HAL 9000 has contributed database resource types (PostgreSQL, SQLite) with transaction-based sandbox strategy: implemented ``DatabaseResourceHandler`` providing full CRUD operations (`read`, `write`, `delete`, `list_children`) and connection validation with automatic credential masking for PostgreSQL and SQLite backends. Includes ``TransactionSandbox`` infrastructure wired into ``SandboxFactory``, BDD test coverage in ``features/database_resources.feature``, and Robot Framework integration tests in ``robot/database_resources.robot`` (PR #10591 / issue #8608, Epic #8568). -* HAL 9000 has contributed the agents plan rollback command (PR #8674 / issue #8557): implemented checkpoint-based plan state restoration with the `agents plan rollback []` CLI command as part of Epic #8493, enabling plans to be restored to previous checkpoints, discarding post-checkpoint decisions, and resuming execution from the rolled-back state. Supported by `--yes/-y`, `--to-checkpoint`, and `--format/-f` flags. Includes comprehensive BDD test coverage (>= 97%) for rollback, decision discarding, and plan resume functionality. -* HAL 9000 has contributed the PyYAML security upgrade (PR #11012 / issue #9055): added `pyyaml>=6.0.3` dependency constraint to address known YAML parsing vulnerabilities. -* HAL 9000 has contributed the DecisionService wiring for PlanExecutor strategize persistence fix (#10813): added decision_service to the PlanExecutor constructor and wired it from the CLI dependency-injection container in `_get_plan_executor()`, plus implemented `_persist_strategy_decisions()` to persist strategy decisions as domain `Decision` objects. -* HAL 9000 has contributed the A2A module rename standardization BDD tests (PR #10583 / issue #8615): comprehensive Behave test suite validating that all 22 A2A symbols are properly exported from `cleveragents.a2a`, no legacy ACP references remain in the module source, and documentation uses correct A2A naming conventions — fixing inline imports, unused behave symbols, cross-scenario context dependencies, and missing type annotations. -* HAL 9000 has contributed the `ActorSelectionOverlay._render` → `_refresh_display` rename fix (PR #11176 / issue #11039, Epic #8174): renamed `_render()` method to `_refresh_display()` to avoid shadowing Textual's `Widget._render()`, fixing a crash in textual >=1.0 where `get_content_height()` would receive `None` and raise `AttributeError: 'NoneType' object has no attribute 'get_height'`. +* HAL 9000 has contributed the Invariant Data Model and Database Schema (PR #8701 / issue #8524): SQLAlchemy ORM model with fields id (UUID), description (text), created_at (timestamp), and is_active (bool); Alembic migration ``m3_001_invariants_table`` creating the ``invariants`` table with index on ``is_active`` for efficient active-filter queries; BDD Behave unit tests and Robot Framework integration tests. -- 2.52.0 From 08b686e0e558d0ebcb2bc0f9acdd49d27c08ccfe Mon Sep 17 00:00:00 2001 From: CleverThis Date: Fri, 15 May 2026 01:30:27 +0000 Subject: [PATCH 3/6] fix(invariants): address review feedback for PR #11037 - Fix Ruff E303: reduce blank lines before InvariantModel to 2 (models.py) - Add type ignore on behave.runner import (invariant_model_steps.py) - Add CheckConstraint('description != ''') on InvariantModel and migration - Fix migration chain: update down_revision to reference latest head m9_003 Also removes deleted file stdio_transport.py that was part of merged-in PR changes.

The model now uses explicit SQLAlchemy column declarations that are fully typed. S3: Removed op.create_index("ix_invariants_updated_at", ...) from the Alembic migration since an index on updated_at was not specified in acceptance criteria. --- features/steps/invariant_model_steps.py | 12 ++++--- robot/helper_invariant_model.py | 1 - .../versions/m3_001_invariants_table.py | 31 ++++++++++++++----- .../infrastructure/database/models.py | 24 +++++++++++--- 4 files changed, 50 insertions(+), 18 deletions(-) diff --git a/features/steps/invariant_model_steps.py b/features/steps/invariant_model_steps.py index d9d1fc151..1f1ed2d6e 100644 --- a/features/steps/invariant_model_steps.py +++ b/features/steps/invariant_model_steps.py @@ -32,11 +32,13 @@ def _setup_db(context: Context) -> None: def _make_invariant(description: str, is_active: bool = True) -> InvariantModel: - """Create an InvariantModel instance with a fresh UUID and timestamp.""" + """Create an InvariantModel instance with a fresh UUID. + + ``created_at`` is auto-populated by the model's server-side default. + """ return InvariantModel( id=str(uuid.uuid4()), description=description, - created_at=datetime.now(tz=UTC).isoformat(), is_active=is_active, ) @@ -66,7 +68,6 @@ def step_new_invariant_empty_desc(context: Context) -> None: context._inv_model = InvariantModel( id=str(uuid.uuid4()), description="", - created_at=datetime.now(tz=UTC).isoformat(), is_active=True, ) @@ -115,8 +116,9 @@ def step_check_is_active_true(context: Context) -> None: @then("the persisted Invariant created_at should not be empty") def step_check_created_at(context: Context) -> None: - assert context._inv_retrieved.created_at, "created_at should not be empty" - assert len(str(context._inv_retrieved.created_at)) > 0 + assert context._inv_retrieved.created_at is not None, ( + "created_at should not be empty" + ) @then("the persisted Invariant id should be a valid UUID") diff --git a/robot/helper_invariant_model.py b/robot/helper_invariant_model.py index 464d65adc..5cabe8d58 100644 --- a/robot/helper_invariant_model.py +++ b/robot/helper_invariant_model.py @@ -29,7 +29,6 @@ def _make_invariant(description: str, is_active: bool = True) -> InvariantModel: return InvariantModel( id=str(uuid.uuid4()), description=description, - created_at=datetime.now(tz=UTC).isoformat(), is_active=is_active, ) diff --git a/src/cleveragents/infrastructure/database/migrations/versions/m3_001_invariants_table.py b/src/cleveragents/infrastructure/database/migrations/versions/m3_001_invariants_table.py index a66b4e757..9159a3209 100644 --- a/src/cleveragents/infrastructure/database/migrations/versions/m3_001_invariants_table.py +++ b/src/cleveragents/infrastructure/database/migrations/versions/m3_001_invariants_table.py @@ -22,17 +22,33 @@ depends_on: str | Sequence[str] | None = None def upgrade() -> None: - """Create the invariants table with indexes on is_active and updated_at. + """Create the invariants table with an index on is_active.
