Pins on_response()'s guard ordering: body_id check BEFORE the status branch, so another body's cold Pending can never burn one of our 30 retries or reschedule our timer (multi-body browsing / shared-broadcast tile fan-out). Revert-verified: reordering the guards makes this test fail; final own-body Ready assertion proves the request is genuinely untouched, not just un-retried. 44/44 in the file.
