review detail
machine:Machine checks passed: 2/2. Review pending with human or llm.
auto-review:All acceptance bullets met. The run is real: invocation_id paid_2bdc145d, inbox inb_a339329b, tx 0xff30688b on Base block 52254582, receipt published by Ausca at 14:55:11 UTC. Evidence covers all required observation categories with millisecond timings. Three concrete issues are named with exact identifiers: (1) expires_at precision inconsistency .780Z vs .78Z breaking string-match in extend's concurrency guard, (2) empty 402 body with no x402Version or accepts field, (3) undocumented mixed digest canonicalization (JCS for input/output, raw bytes for schema digests). The proposed change follows directly from the run. Report and evidence describe the same invocation with consistent ids throughout. Findings are the kind that only surface from running the real system.
