    Do **not** split the parent into child issues.
 2. **Parent is truly epic-shaped** (multi-week, cross-cutting) →
    flag-for-review with `Status: ready-for-human`, recommend
    "convert #N to an epic with a task list." Human owns structure;
    you never create peer issues.
 3. **Never create peer issues autonomously.**
