Bug Report

Feature Area: Sandbox and Checkpoint / Correction Model
Tested By: UAT worker (uat-pool-1), feature area: Sandbox and Checkpoint
Severity: High (append correction mode is non-functional — no real child plan is created)


What Was Tested

The agents plan correct --mode append command was analyzed to verify it creates and executes a new child plan as defined in the specification (§CLI Commands — agents plan correct, line 28944).

Expected Behavior (from spec)

The spec defines --mode append (line 28944):

agents plan correct <decision_id> --mode=append --guidance "<description of the fix>"
Creates a new child plan to fix the outcome without rewriting history

The spec's plan correct output for append mode shows (lines 15091–15110):

╭─ Correction ─────────────────────────────────────╮
│ Mode: append                                     │
│ Impact: adds to existing subtree, no rollback    │
│ New Decision: 01HXM9C3Z5T2Q8K2E9H7K3W2M8         │
│ Appended After: 01HXM9A1C2Q7W3R5G8Z0P4Q1X9       │
│ Attempt: 2                                       │
╰──────────────────────────────────────────────────╯

╭─ Append Detail ─────────────────────────────────────────────────╮
│ Original decision preserved: yes                                │
│ Existing artifacts kept: yes                                    │
│ Additional work: appended as new child plan                     │
│ The original 5 artifacts remain; a new child plan will add      │
│ rate-limiting code on top of the existing auth changes.         │
╰─────────────────────────────────────────────────────────────────╯

╭─ Queued ──────────╮
│ New child: 1      │
│ ETA: 2m           │
╰───────────────────╯

Actual Behavior (from code)

The CorrectionService.execute_append() in src/cleveragents/application/services/correction_service.py (lines 590–638):

child_plan_id = str(ULID())   # ← generates a fake ULID
new_decision_id = str(ULID()) # ← generates a fake ULID

result = CorrectionResult(
    correction_id=correction_id,
    status=CorrectionStatus.APPLIED,
    new_decisions=[new_decision_id],
    spawned_child_plan_id=child_plan_id,  # ← fake ULID, no real plan created
)

The method:

  • Does NOT create a real child plan in the database
  • Does NOT start executing the child plan
  • Does NOT link the child plan to the parent plan's decision tree
  • Does NOT create a subplan_spawn decision in the parent plan
  • Returns a fake child_plan_id ULID that doesn't correspond to any real plan

Code Location

src/cleveragents/application/services/correction_service.py, execute_append() method (lines 590–638)

Steps to Reproduce

  1. Create and execute a plan to generate several decisions
  2. Run agents plan correct <DECISION_ID> --mode append --guidance "Add rate limiting"
  3. Expected: A new child plan is created and queued for execution
  4. Actual: Command reports success with a fake child plan ID that doesn't exist in the system

Verification

# After running plan correct --mode append:
agents plan list  # The "child plan" won't appear here
agents plan status <spawned_child_plan_id>  # Will return "not found"

Impact

  • Non-functional: The append correction mode is completely non-functional — no real child plan is created
  • Data integrity: The returned spawned_child_plan_id is a fake ULID that doesn't correspond to any real plan
  • User confusion: Users expect a child plan to be created and executed, but nothing happens

Hierarchical Compliance Fix: This issue was detected as an orphan (no parent Epic).

Solution: Linked to Epic #4959 (EPIC: Correction Engine — Revert & Append Modes with plan.attempt Tracking) based on scope — this bug is about agents plan correct --mode append which is the core deliverable of that Epic.

Hierarchy: Issue #5097 → Epic #4959 → Legendary #4942
