This prevents invalid decisions (e.g., `tool_invocation` during Strategize, `strategy_choice` during Execute) from being persisted. ### Changes - **Exception** (`cleveragents.core.exceptions`): Added `DecisionPhaseViolationError(BusinessRuleViolation)` with `decision_type`, `plan_phase`, and `allowed_types` attributes. - **Phase constants** (`cleveragents.domain.models.core.decision`): - `resource_selection` added to `EXECUTE_TYPES` — now phase-agnostic (Strategize or Execute) per ADR-007 L72 and ADR-033 L74. - `subplan_spawn` / `subplan_parallel_spawn` in both sets; code comment documents divergence from ADRs per M4 subplan model (ticket #931). - `USER_INTERVENTION` remains phase-agnostic (both sets). - Module-level docstring table updated to match actual assignments. - `is_any_phase_type` property updated to check membership in both sets dynamically (was hardcoded to `USER_INTERVENTION` only). - **Phase-gating module** (`cleveragents.application.services.phase_gating`): - Extracted from `DecisionService` to reduce `decision_service.py` line count (1010 → 913) and isolate the phase-gating concern. - `PHASE_ALLOWED_TYPES` typed as `Mapping[PlanPhase, frozenset[DecisionType]]`. - `resolve_plan_phase()` helper: supports explicit parameter, DB lookup, and graceful skip. - `validate_phase_gating()` enforcement raises `DecisionPhaseViolationError`. - Exception narrowing: DB lookup catches `(DatabaseError, OperationalError, OSError)` instead of bare `except Exception` — only absorbs infrastructure failures, not programming errors. - `# TODO(pg-migration):` marker on TOCTOU race documentation for future PostgreSQL migration. - **Decision service** (`cleveragents.application.services.decision_service`): - Added `plan_phase` parameter to `record_decision()`. - Invalid `plan_phase` string now raises `ValidationError` (was uncaught `ValueError`). - Imports and delegates to `phase_gating` module for all phase-gating logic. - `PHASE_ALLOWED_TYPES` re-exported in `__all__` for backward compatibility. - **CHANGELOG**: Added behavioral change entry for `resource_selection` reclassification. - **Backward compatibility**: Phase-gating is opt-in — when neither `plan_phase` is provided nor a UnitOfWork is wired, validation is skipped, preserving all existing callers. - **Unrelated drive-by reverted**: Removed `ULID_PATTERN` from `decision.py` `__all__` (was an unrelated export addition). - **Tests**: - 36 Behave scenarios covering valid/invalid types per phase, phase-agnostic acceptance, DB-based resolution (Strategize and Execute plans), unknown plan in DB, PlanPhase enum pass-through, error attributes, and ungated phases. - 11 new Behave scenarios for `is_any_phase_type`: 4 dual-phase types (true) + 7 single-phase types (false), including `prompt_definition` root test. - 6 Robot Framework integration tests with stderr assertions. - Updated `consolidated_decision.feature` for new `EXECUTE_TYPES` member count (8 members). - Test cleanup now calls `uow.engine.dispose()` before file deletion. - `tempfile.mktemp()` replaced with `tempfile.mkstemp()`. - Inline imports moved to module top-level per CONTRIBUTING.md. - Flaky concurrency test timing increased in `subplan_execution_steps.py`. ### Review Round 1 + 2 Fixes | # | Finding | Resolution | |---|---------|------------| | P1-1 | `except Exception` too broad in `_resolve_plan_phase` | Narrowed to `(DatabaseError, OperationalError, OSError)` — matches codebase pattern | | P2-2 | `decision_service.py` at 1010 lines | Extracted to `phase_gating.py` module (1010 → 913 lines) | | P2-3 | TOCTOU race — no programmatic guard | Added `# TODO(pg-migration):` marker with actionable guidance | | P2-4 | `resource_selection` reclassification needs CHANGELOG | Added CHANGELOG entry documenting behavioral change | | P2-7 | `is_any_phase_type` BDD gap for dual-phase types | Added 11 parametrized scenarios covering all 4 dual-phase + 7 single-phase types | | P3-5 | `ULID_PATTERN` export is unrelated drive-by | Reverted — removed from `decision.py` `__all__` | | P3-6 | `decision.py` at 514 lines (now 513) | No action — reviewer accepted as marginally over | ### Quality Gates | Session | Result | |---------|--------| | lint | PASS | | typecheck | PASS (0 errors) | | unit_tests | PASS (11,153 scenarios, 0 failures) | | integration_tests | PASS (1,563 tests, 0 failures) | | e2e_tests | PASS (16 tests, 0 failures) | | coverage_report | 97% (threshold: 97%) | Closes #931 Reviewed-on: #973 Co-authored-by: Rui Hu <rui.hu@cleverthis.com> Co-committed-by: Rui Hu <rui.hu@cleverthis.com>	2026-03-19 07:53:43 +00:00
