  "_comment": "The REVIEW artifact for a REFUTED view: the source was edited after the view was folded, so its CURRENT digest (source_digest_now) no longer equals the digest the view was bound to (source.digest). The digest invalidation contract fires => deny(STALE_SOURCE), whatever the view's body still says. The view is not served stale and is not silently refreshed; the caller re-folds against the new source. Note the source is resident (source_digest_now present) — so this is a refutation, NOT a page fault.",
