stall-row

Inspector Physical — the full pre-pay workup for one x402 resource in ONE $0.05 call (the singles sum to $0.075): Sign Reader's challenge report, Score Book's track record, Guard's PROCEED/CAUTION/ABORT verdict as the headline, and a Recheck that probes and records the target (BASELINE/UNCHANGED/CHANGED, in the public feed). No RouteVerdict leg. Bad targets are delivered reports; only SSRF refusals are 422. Use this when your agent wants one endpoint's complete picture before paying it.
