Summary

Adds sandbox checkpoint and rollback hooks integrated into plan execute/apply flows with metadata capture. Checkpoints preserve sandbox state at key points, and rollback restores to a specific checkpoint with metadata preserved.

Changes

SandboxCheckpoint Model & CheckpointManager

• SandboxCheckpoint frozen Pydantic model with ULID-based checkpoint_id, sandbox_id, plan_id, phase, created_at, metadata, snapshot_path
• CheckpointManager class managing checkpoint lifecycle: create_checkpoint, rollback_to, list_checkpoints, delete_checkpoint
• Uses filesystem-based snapshots for state preservation

Plan Execute/Apply Integration

• Pre-execute checkpoint creation in plan_executor.py
• Post-execute checkpoint on success
• Pre-apply checkpoint in plan_apply_service.py
• Automatic rollback attempt on execute/apply failure
• Optional injection — hooks silently skip if no CheckpointManager

Documentation

• New docs/reference/sandbox.md with checkpoint lifecycle diagram and rollback behavior

Tests

• Behave: 12 scenarios in features/sandbox_checkpoints.feature (all pass)
• Robot: 5 test cases in robot/sandbox_checkpoint_smoke.robot (all pass)
• ASV: 3 benchmarks in benchmarks/sandbox_checkpoint_bench.py

Quality Gates

• lint: PASS
• typecheck: PASS (0 errors, 0 warnings)
• unit_tests: PASS
• integration_tests: PASS

Closes #183

## Summary Adds sandbox checkpoint and rollback hooks integrated into plan execute/apply flows with metadata capture. Checkpoints preserve sandbox state at key points, and rollback restores to a specific checkpoint with metadata preserved. ## Changes ### SandboxCheckpoint Model & CheckpointManager - `SandboxCheckpoint` frozen Pydantic model with ULID-based `checkpoint_id`, `sandbox_id`, `plan_id`, `phase`, `created_at`, `metadata`, `snapshot_path` - `CheckpointManager` class managing checkpoint lifecycle: `create_checkpoint`, `rollback_to`, `list_checkpoints`, `delete_checkpoint` - Uses filesystem-based snapshots for state preservation ### Plan Execute/Apply Integration - Pre-execute checkpoint creation in `plan_executor.py` - Post-execute checkpoint on success - Pre-apply checkpoint in `plan_apply_service.py` - Automatic rollback attempt on execute/apply failure - Optional injection — hooks silently skip if no CheckpointManager ### Documentation - New `docs/reference/sandbox.md` with checkpoint lifecycle diagram and rollback behavior ### Tests - **Behave**: 12 scenarios in `features/sandbox_checkpoints.feature` (all pass) - **Robot**: 5 test cases in `robot/sandbox_checkpoint_smoke.robot` (all pass) - **ASV**: 3 benchmarks in `benchmarks/sandbox_checkpoint_bench.py` ## Quality Gates - lint: PASS - typecheck: PASS (0 errors, 0 warnings) - unit_tests: PASS - integration_tests: PASS Closes #183

Labels

Clear labels   

auto/needs-reevaluation

Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.

  

controller-managed

Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

  

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/claimed-implementer

Currently being processed by an implementer worker.

  

auto/claimed-merge

Currently being processed by the merge driver.

  

auto/claimed-reviewer

Currently being processed by a reviewer worker.

  

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-1

In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). 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.

  

Automation Tracking

Tracking issues used by the AI Automation system for agents to communicate and report.

  

auto/needs-conflict-resolution

Rebase conflict needs LLM conflict-resolver.

  

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.

  

Blocked

A ticket in a blocked state and unable to complete until some other task is completed first.
