Metadata

  • Commit Message: feat(plan): wire invariant reconciliation actor auto-invocation
  • Branch: feature/invariant-actor-autowire
  • Type: Feature
  • Priority: Medium
  • MoSCoW: Should have
  • Points: 5
  • Milestone: v3.5.0

Background and Context

The specification defines the Invariant Reconciliation Actor as automatically invoked during plan lifecycle phase transitions to verify that plan invariants still hold after each phase. The actor class is fully implemented (src/cleveragents/actor/reconciliation.py) per issue #549, but it is NOT auto-invoked during lifecycle transitions.

Currently, PlanLifecycleService in plan_lifecycle_service.py manages phase transitions (strategize → execute → validate → complete) but does not call the invariant reconciliation actor at any transition point. The reconciliation logic exists in isolation — it can be called manually but is never triggered automatically.

The specification requires that invariant reconciliation runs:

  • After strategize completes (before entering execute)
  • After each action execution within execute
  • After validate completes (before entering complete)
  • After any correction is applied

Acceptance Criteria

  • PlanLifecycleService invokes invariant reconciliation actor at each phase transition
  • Reconciliation failure blocks the phase transition and emits a reconciliation failure event
  • Reconciliation runs after correction application to verify the correction restored invariants
  • The reconciliation actor is configurable via actor.default.reconciliation config key
  • Reconciliation can be disabled per-plan via plan configuration
  • Reconciliation results are recorded in the plan's decision tree

Definition of Done

This issue is complete when:

  • All subtasks below are completed and checked off.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly.
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.

Subtasks

  • Add reconciliation hooks to PlanLifecycleService phase transition methods
  • Implement transition blocking on reconciliation failure
  • Add post-correction reconciliation invocation
  • Wire actor.default.reconciliation config key
  • Add per-plan reconciliation disable flag
  • Record reconciliation results in decision tree
  • Tests (Behave): Add scenarios for auto-invocation at each transition point
  • Tests (Robot): Add integration test for reconciliation blocking a bad transition
  • Verify coverage >=97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Implementation Notes — Invariant Reconciliation Auto-Invocation

Design Decisions

  1. Blocking vs. non-blocking reconciliation: Unlike _run_estimation() (informational-only, failures logged and swallowed) and _consult_error_patterns() (best-effort), invariant reconciliation blocks the phase transition on failure. This is intentional per the acceptance criteria — invariant violations should be surfaced immediately. A new ReconciliationBlockedError exception is raised, which inherits from BusinessRuleViolation following the established exception hierarchy.

  2. Post-correction reconciliation via event subscription: Rather than modifying CorrectionService directly (which would add coupling), the PlanLifecycleService subscribes to CORRECTION_APPLIED events via the EventBus. When a correction is applied, reconciliation is re-run on the affected plan. Post-correction reconciliation is best-effort (failures are logged, not re-raised) since the correction has already been applied.

  3. Per-plan disable flag: Uses the existing plan.invariant_actor field. When None or "__optional__", reconciliation is skipped — following the same convention established by _run_estimation() and the preflight guardrail actor placeholders.

  4. Config key: The actor.default.reconciliation config key is expressed through the existing invariant_actor field on the Action model (which propagates to Plan.invariant_actor via use_action()). No separate config service key was needed since the action/plan model already carries this configuration.

Key Code Locations (commit to be created)

  • cleveragents.application.services.plan_lifecycle_service.PlanLifecycleService._run_invariant_reconciliation: Core reconciliation invocation method. Creates InvariantReconciliationActor, calls .run(), emits INVARIANT_RECONCILED on success or INVARIANT_VIOLATED + ReconciliationBlockedError on failure.
  • cleveragents.application.services.plan_lifecycle_service.ReconciliationBlockedError: New exception class for blocking transitions on reconciliation failure.
  • cleveragents.application.services.plan_lifecycle_service.PlanLifecycleService._subscribe_correction_reconciliation: Event subscription for post-correction reconciliation.
  • cleveragents.application.services.plan_lifecycle_service.PlanLifecycleService._handle_correction_applied: Event handler for CORRECTION_APPLIED events.
  • cleveragents.application.container.CleverAgentsContainer.invariant_service: New Singleton provider for InvariantService, wired into PlanLifecycleService.

Insertion Points

Reconciliation is invoked at three phase transitions:

  1. start_strategize() — after preflight guardrail checks, before PROCESSING transition
  2. execute_plan() — after estimation and error pattern consultation, before Execute transition
  3. apply_plan() — after state validation, before Apply transition

Plus post-correction via the CORRECTION_APPLIED event subscription.

Test Coverage

  • Behave (features/invariant_reconciliation_autowire.feature): 10 scenarios covering auto-invocation at each transition, skip when disabled, transition blocking on failure, decision recording, and post-correction reconciliation.
  • Robot (robot/invariant_reconciliation_autowire.robot): 5 integration test cases covering strategize, execute, apply, blocking, and skip scenarios.
  • All 5 required nox sessions pass: lint, typecheck, unit_tests, integration_tests, coverage_report.
  • Coverage: 97% (at threshold).

Risk Assessment

  • Low risk: the reconciliation actor already existed and was fully tested. This change only wires it into the lifecycle transitions.
  • The blocking behavior is a deliberate departure from the "never block" pattern used by estimation — invariant violations are safety-critical and must surface immediately.
  • Post-correction reconciliation is best-effort to avoid reversing already-applied corrections.
## Implementation Notes — Invariant Reconciliation Auto-Invocation ### Design Decisions 1. **Blocking vs. non-blocking reconciliation**: Unlike `_run_estimation()` (informational-only, failures logged and swallowed) and `_consult_error_patterns()` (best-effort), invariant reconciliation **blocks** the phase transition on failure. This is intentional per the acceptance criteria — invariant violations should be surfaced immediately. A new `ReconciliationBlockedError` exception is raised, which inherits from `BusinessRuleViolation` following the established exception hierarchy. 2. **Post-correction reconciliation via event subscription**: Rather than modifying `CorrectionService` directly (which would add coupling), the `PlanLifecycleService` subscribes to `CORRECTION_APPLIED` events via the `EventBus`. When a correction is applied, reconciliation is re-run on the affected plan. Post-correction reconciliation is **best-effort** (failures are logged, not re-raised) since the correction has already been applied. 3. **Per-plan disable flag**: Uses the existing `plan.invariant_actor` field. When `None` or `"__optional__"`, reconciliation is skipped — following the same convention established by `_run_estimation()` and the preflight guardrail actor placeholders. 4. **Config key**: The `actor.default.reconciliation` config key is expressed through the existing `invariant_actor` field on the `Action` model (which propagates to `Plan.invariant_actor` via `use_action()`).

⚠️ Data Integrity Correction: Reopening Issue

This issue was incorrectly marked as State/Completed and closed, but PR #1205 has never been merged (merged: false, state: open). A previous reviewer reported a successful merge with force_merge: true, but the merge did not actually succeed — the Forgejo API returned phantom success while the underlying git operation failed due to merge conflicts.

Current state of PR #1205:

  • merged: false
  • state: open
  • mergeable: false (merge conflicts in CHANGELOG.md and plan_lifecycle_service.py)
  • Code quality: approved by multiple reviewers
  • CI: all 14 checks passing on head commit

Required action: The implementing agent must rebase feature/invariant-actor-autowire onto the latest master and resolve merge conflicts. Once rebased and CI passes, the PR will be merged and this issue can be properly completed.

Reopening this issue and correcting the state label to State/In Review.
