Metadata

Background and Context

The CleverAgents system needs checkpoint creation and rollback functionality. The CheckpointManager is the core service that creates plan state snapshots and restores them. Currently CheckpointManager.rollback_to() has issues with missing sandbox_path handling.

Expected Behavior

  • CheckpointManager.create_checkpoint(plan_id) creates a snapshot of the current plan state
  • CheckpointManager.rollback_to(checkpoint_id) restores the plan to the checkpoint state
  • rollback_to() correctly handles missing sandbox_path (uses correct path resolution)
  • Checkpoints are persisted to the checkpoints DB table
  • Auto-checkpoint creation is configurable via sandbox.checkpoint.auto-create-on

Acceptance Criteria

  • CheckpointManager service implemented in src/cleveragents/checkpoints/
  • CheckpointManager.create_checkpoint() persists checkpoint to DB
  • CheckpointManager.rollback_to() correctly resolves sandbox_path
  • sandbox.checkpoint.auto-create-on config key registered and functional
  • checkpoints DB table schema matches spec DDL
  • Unit tests (Behave) cover create and rollback scenarios
  • Integration test (Robot) verifies checkpoint persistence

Subtasks

  • Define checkpoints DB table schema (migration)
  • Implement CheckpointManager service class
  • Implement create_checkpoint() with DB persistence
  • Fix rollback_to() sandbox_path resolution
  • Register sandbox.checkpoint.auto-create-on config key
  • Tests (Behave): Add scenarios for checkpoint operations
  • Tests (Robot): Add integration test
  • Verify coverage >=97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

  • All subtasks above 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.

auto/blocked-by-deps
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.
 auto/ci-timeout
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

 auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.
 auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.
 auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

 auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.
 auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

 auto/needs-implementer
Failing CI needs implementer attention.
 auto/postmortem
Documenting a driver incident or rollback.
 auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.
 auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.
 auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.
 auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.
 auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
 auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
