Hardening the inline blocks lacked: bounded retry on 429/5xx and\n               defensive envelope parsing (deepseek_run._extract_message — no raw\n               resp[\"choices\"][0]... indexing anywhere).\n\n          Exit codes: 0 with /tmp/review.json written = review produced; 0 without the\n          file = substrate absent this run (provider outage, missing key, or scrub\n          block — the submit step warns); nonzero only for operator errors (unknown\n          provider, unreadable diff) that must fail the check loudly.\n\n          Review-body markers are LOAD-BEARING: verifier-gate.yml de-collapses the\n          shared github-actions[bot] login by matching these exact strings.
