Metadata

  • Commit message: feat(plans): implement checkpoint creation and durable persistence for plan execution
  • Branch name: feat/v3.3.0-checkpoint-creation-persistence

Background and Context

Checkpoints must be automatically created at configurable execution milestones and persisted to durable storage to survive process restarts. Without checkpoints, plan execution cannot be resumed after failures, and rollback to a known-good state is impossible.

Expected Behavior

Current behavior: No checkpoint creation or persistence mechanism exists; plan execution state is lost on process restart or failure.

Expected behavior: Checkpoints are created at configurable execution milestones and persisted to durable storage. Checkpoint metadata includes timestamp, step index, state hash, and label. A checkpoint listing and retrieval API is available.

Acceptance Criteria

  • Checkpoints created at configurable execution milestones
  • Checkpoints persisted to durable storage (survive restarts)
  • Checkpoint metadata includes timestamp, step index, state hash, label
  • Checkpoint listing and retrieval API works
  • Unit tests pass with coverage >= 97%

Subtasks

  • Design checkpoint data model (metadata, state snapshot, persistence format)
  • Implement checkpoint creation at configurable milestones
  • Implement checkpoint persistence layer (database-backed)
  • Implement checkpoint listing and retrieval API
  • Write unit tests
  • Verify coverage >= 97%

Definition of Done

This issue should be closed when:

  • Checkpoints are automatically created at configurable milestones during plan execution
  • Checkpoints survive process restarts (durable database-backed persistence)
  • Checkpoint metadata is complete (timestamp, step index, state hash, label)
  • Listing and retrieval API works correctly
  • All unit tests pass with >= 97% coverage
  • Code has been reviewed and merged to the target branch
