Metadata

  • Commit Message: feat(concurrency): add plan resume
  • Branch: feature/m4-concurrency-resume

Background

Step-level progress is persisted, and plan resume restores execution from the last completed step with graceful shutdown handling. Resume checkpoints are tied to decision IDs and sandbox checkpoints. Resume eligibility is validated (non-terminal plans only).

Acceptance Criteria

  • Persist step-level progress and implement plan resume with graceful shutdown handling.
  • Add resume checkpoints tied to decision IDs and sandbox checkpoints.
  • Validate resume eligibility (non-terminal plans only) and emit clear error for invalid states.
  • Add plan resume --dry-run to show where execution will resume without changing state.
  • Add resume metadata in plan (last_completed_step, last_checkpoint_id).

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, followed by a blank line, then
    additional lines providing relevant details about the implementation. The
    commit body should be appropriate in size for a commit message and relatively
    complete in describing what was done.
  • 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

  • Persist step-level progress and implement plan resume with graceful shutdown handling.
  • Add resume checkpoints tied to decision IDs and sandbox checkpoints.
  • Validate resume eligibility (non-terminal plans only) and emit clear error for invalid states.
  • Add plan resume --dry-run to show where execution will resume without changing state.
  • Add resume metadata in plan (last_completed_step, last_checkpoint_id).
  • Add CLI output for resume summary (phase, step, decision_id) before executing.
  • Update plan lifecycle docs for resume behavior.
  • Add resume flow example and error cases.
  • Tests (Behave): Add features/plan_resume.feature scenarios.
  • Tests (Robot): Add resume integration tests.
  • Tests (ASV): Add benchmarks/plan_resume_bench.py for resume overhead baseline.
  • Verify coverage >=97% via nox -s coverage_report. If coverage is <97% then review the current unit test coverage report at build/coverage.xml and use it to write new Behave based unit tests to improve code coverage. Specifically, write Behave style unit tests that are descriptively named and specifically improves coverage on whichever file has the most uncovered lines by writing tests that will target the uncovered lines in the report. Once that is done rerun nox -s coverage_report to verify all tests pass and coverage is above >=97%. Only mark this as complete once coverage is >=97%, if not repeat this task as many times as is needed until coverage reaches >=97%.
  • Run nox (all default sessions, including benchmark), fix any errors if needed ensuring nox passes across entire code base, do not ignore any failure even if it seems unrelated to this commit, fix it.

  • Plan model: Added last_completed_step and last_checkpoint_id fields
  • PlanResumeService: Eligibility validation, checkpoint recording, dry-run/live resume, graceful shutdown
  • CLI: plan resume <plan_id> [--dry-run] command with resume summary output
  • Docs: ADR-006 updated with resume behavior section

Tests:

  • 24 Behave scenarios (all passing)
  • 10 Robot Framework integration tests
  • ASV benchmarks for resume overhead
