  • Commit message: feat: implement invariant enforcement and validation pipeline
  • Branch name: feat/invariant-enforcement-validation-pipeline

Background and Context

The v3.2.0 milestone (M3: Decisions + Validations + Invariants) requires that invariants are enforced during the Strategize phase and that output validation is flexible (checking structural components, not exact character matching). The validation pipeline is the quality assurance layer that ensures plan outputs meet defined criteria before proceeding.

Invariant enforcement is a critical safety mechanism that prevents plans from violating user-defined constraints. Without proper invariant enforcement, the system cannot guarantee that plans respect user-defined boundaries. The validation pipeline must be flexible enough to check structural components without requiring exact character matching, which would make tests brittle.

This Epic groups all invariant enforcement and validation pipeline issues that must be resolved for M3 acceptance.

Current Behavior

Invariants may not be enforced during Strategize. Output validation may use exact character matching instead of structural component checking. Validation pipeline may not properly gate plan progression.

Expected Behavior

Invariants are enforced during Strategize phase. Violations cause plan correction or rejection. Output validation checks structural components (not exact character matching). Validation pipeline properly gates plan progression at each phase transition.

Acceptance Criteria

  • Invariants are enforced during Strategize phase
  • Invariant violations cause plan correction or rejection with clear error messages
  • Output validation checks structural components (not exact character matching)
  • Validation pipeline gates plan progression at each phase transition
  • Validation failures produce actionable error messages
  • Validation results are persisted to the decision tree
  • All child issues are closed and merged
  • Test coverage >= 97% for invariant enforcement and validation pipeline

Subtasks

  • Implement invariant enforcement in Strategize phase
  • Implement invariant violation handling (correction/rejection)
  • Implement structural component validation (not exact matching)
  • Implement validation pipeline phase transition gating
  • Implement validation result persistence to decision tree
  • Write unit tests for invariant enforcement
  • Write integration tests for validation pipeline
  • Write E2E tests for invariant-gated plan execution

Parent Legendary

Depends on: Legendary #375 (Execution Pipeline & Decisions)

Definition of Done

Epic complete when all child issues are closed, invariants are enforced during Strategize, and output validation uses structural component checking.

Implementation Attempt — Default Tier — Success

Implemented invariant enforcement and validation pipeline for Epic #8137 (M3).

Three new modules created:

  • src/cleveragents/application/services/invariant_enforcer.py — runtime violation detection with actionable error messages
  • src/cleveragents/application/services/structural_component_validator.py — flexible structural component matching (substring, wildcard, regex, field paths)
  • src/cleveragents/application/services/phase_transition_gate.py — phase transition gating for Strategize→Execute and Execute→Apply

Includes 15 Behave BDD test scenarios across 3 feature files with step definitions.

All quality gates passing: lint ✓, typecheck ✓.
PR #11151 created: #11151
