- What was implemented
- Added PLAN_ROLLED_BACK event type to the EventType enum at src/cleveragents/infrastructure/events/types.py to properly represent successful rollbacks in the domain model.
- Implemented rollback_plan(plan_id: str, checkpoint_id: str) -> RollbackResult in PlanLifecycleService (src/cleveragents/application/services/plan_lifecycle_service.py) with:
- Plan state validation: rejects rollback when the plan is in terminal APPLIED or CANCELLED states.
- Delegation to CheckpointService.selective_rollback() to perform the actual rollback logic and obtain a RollbackResult.
- Emission of PLAN_ROLLED_BACK as a domain event to reflect the completed rollback.
- checkpoint_service is accepted as an optional constructor parameter; if not provided, a PlanError is raised to preserve backward compatibility.
- Updated CLI behavior in src/cleveragents/cli/commands/plan.py so agents plan rollback routes through PlanLifecycleService.rollback_plan() rather than calling CheckpointService.selective_rollback() directly.
- Updated PlanLifecycleService module docstring to include rollback_plan in the documented API.
- Added Behave feature file features/plan_lifecycle_rollback.feature with 11 scenarios covering state validation, domain events, and delegation.
- Added step implementations in features/steps/plan_lifecycle_rollback_steps.py to support the new scenarios.
- Key design decisions
- rollback_plan returns RollbackResult (the same result type produced by CheckpointService.selective_rollback) so the CLI can display rollback details consistently.
- Terminal states APPLIED and CANCELLED are disallowed for rollback to prevent inconsistent or invalid state transitions.
- checkpoint_service is optional in the PlanLifecycleService constructor; when omitted (None), a PlanError is raised to retain backward compatibility while signaling explicit dependency requirements.
- CLI UI remains powered by CheckpointService for metadata enrichment (e.g., confirmation prompts), but the actual rollback action is performed via PlanLifecycleService to ensure proper domain workflow and event emission.
- Technical implications
- All rollback logic now flows through the domain service layer (PlanLifecycleService) to preserve invariants and emit domain events, rather than allowing ad-hoc UI routes to bypass service validation.
- The UI can still retrieve checkpoint metadata for user confirmation, but the operation that modifies state uses the new rollback_plan pathway.
- Tests and behavior coverage were expanded via the new Behave feature and step implementations to validate state handling, events, and delegation.
