Verify iterates manifest file entries, confirms each blob exists in the store, and re-hashes the content to detect corruption. Includes unit tests for the ok, hash-mismatch, and blob-missing cases, plus a thin CLI wrapper that exits non-zero on any failure. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
