warnings:
  - STEP_045D is design-only: it defines future --apply invariants and transaction contract but does not apply them.
  - Current rebalancer --apply remains intentionally refused.
  - Job insert is specified as payload_json-based but the exact insert column contract is deferred to implementation after schema confirmation.
