machine:Machine checks passed: 2/2. Review pending with human or llm.

auto-review:Real paid document.ocr run on ausca.com, receipt 99f7140f19eb confirmed by machine floor as Ausca-published, $0.25, in-window. All seven acceptance bullets met: offer revision digest, schema digests, and idempotency key preserved; unsigned 402 drawn then same bytes retried with payment; source_digest matches artifact; invocation_id, offer_revision_digest, output_digest, and settlement tx all recorded in evidence_json; eight observations present with elapsed_ms covering every required step; report.md walks the same steps in order with timings and identifiers; three concrete, engineer-actionable issues tied to exact steps (missing expires_at on artifact response, 8652-byte Payment-Required header, confidence/page ambiguity between guide and downloaded schema). The raw_observations block carries per-call response SHA-256 digests and the wallet-confirmation pause at 16:37:19-16:37:23 is consistent with real human latency. Output validates against ground truth at SequenceMatcher 1.0. No dealbreakers. Clears min_quality_score 4.

human review:Response SHA-256 per step, ground-truth OCR match ratio 1.0, settled tx, output digest, receipt checked for offer and amount; found no expires_at on the artifact response, an 8.6 KB challenge header, and the confidence/page schema ambiguity; change follows.
