Bug Report

Feature Area: Sandbox and Checkpoint
Tested By: UAT worker (uat-pool-1), feature area: Sandbox and Checkpoint
Severity: High (rollback is incomplete — decision tree and child plans are not reverted, leaving the plan in an inconsistent state)

What Was Tested

The agents plan rollback command was analyzed to verify it performs all required rollback operations as defined in the specification (§CLI Commands — agents plan rollback, lines 16044–16045 and §Checkpointing in Execute, lines 19396–19441).

Expected Behavior (from spec)

The spec states (line 16044–16045):

Rollback a plan sandbox to a previous checkpoint. All changes made after the target checkpoint are reverted: files are restored or removed, decisions are discarded, and tool calls are undone. Child plans spawned after the checkpoint are invalidated.

The spec also defines the plan rollback output as including:

impact.child_plans_invalidated: number of child plans cancelled
impact.decisions_after_cp: number of decisions discarded
impact.tool_calls_after_cp: number of tool calls undone

Actual Behavior (from code)

The rollback_plan function in src/cleveragents/cli/commands/plan.py calls svc.selective_rollback(plan_id, resolved_checkpoint_id), which delegates to CheckpointService.rollback_to_checkpoint().

CheckpointService.rollback_to_checkpoint() (in src/cleveragents/application/services/checkpoint_service.py) only performs:

git reset --hard <sandbox_ref> — restores files ✓
git clean -fd — removes untracked files ✓

It does NOT:

❌ Invalidate/supersede decisions created after the checkpoint
❌ Cancel child plans spawned after the checkpoint
❌ Track or report tool calls undone

After rollback, the plan's decision tree still contains all decisions made after the checkpoint, even though the sandbox files have been reverted. This creates an inconsistent state where the decision tree no longer reflects the actual sandbox state.

Code Location

src/cleveragents/application/services/checkpoint_service.py, rollback_to_checkpoint() method (lines ~200–280)
src/cleveragents/cli/commands/plan.py, rollback_plan() function (lines 3533–3800)

Steps to Reproduce

Create a plan and execute it to generate several decisions and child plans
Create a checkpoint at an early point
Continue execution to create more decisions and child plans
Run agents plan rollback <PLAN_ID> <CHECKPOINT_ID>
Expected: Files reverted, decisions after checkpoint invalidated, child plans cancelled
Actual: Only files are reverted; decisions and child plans remain unchanged

Impact

This is a critical correctness issue for the rollback feature:

The plan's decision tree is inconsistent with the sandbox state after rollback
Child plans that were spawned after the checkpoint remain active and may continue executing against the reverted sandbox
Re-running agents plan execute after rollback will encounter stale decisions that reference files that no longer exist
The spec's safety guarantee ("All changes made after the target checkpoint are reverted") is violated
