Scenarios:

1. Created canonical plan with --brief $'- Goal alpha\n- Goal beta'.
2. Passed essential criteria C001/C002 for G001-goal-alpha.
3. Ran checkpoint --goal-id G001-goal-alpha --status complete --codex-goal-json <aggregate active> --json.
   • Observed next.goal.id == "G002-goal-beta".
   • Observed next.goal.status == "in_progress".

5. Ran checkpoint --status failed on a fresh plan.
