Claude adversarial pass (post-red-team): (1) the same-hash drift defense had a foreign-fixtures_hash carve-out a doctored committed baseline could slip through — removed; ANY committed-vs-main divergence must now be receipts-backed by the actual run (foreign-corpus callers opt out via --committed-baseline); (2) same corpus must yield identical gold_total — free invariant now breached on any scorer/loader drift; (3) hybrid continuity writers can no longer double-count into the write-back cell; (4) retrieval gold on assistant turns (never replayed) is now a validation error. Hygiene: gate script cleans its defaulted temp artifact, CI uses runner.temp instead of a fixed /tmp path, codex preamble failures are loud, accepted residuals (justification is human-judged, count-preserving dilution, no auto-ratchet) documented in BRAINBENCH.md.
