/**
 * Per-attempt receipts.
 *
 * Every attempt gets an immutable receipt: run_id, attempt_id,
 * lease_generation, launch token (clientToken + startedBy), task id,
 * timestamps, image + bundle digests, the frozen policy, and — once the
 * attempt reaches a terminal outcome — exit code and artifact/log pointers.
 * Receipts are written through the storage adapter; the terminal receipt
 * finalizes the run row.
