  "description": "Span forensics + fork-safety verdict over customer-supplied recorded spans: submit one span (or a run's span set) and get a forensic report \u2014 canonicalization, env_digest binding, completeness, stub coverage \u2014 and a fork-safety verdict (FORK-SAFE-LIVE / FORK-SAFE-STUBBED / FORK-DEGRADED / FORK-UNSAFE) issued before any execution, for $0.01 per span checked. The verdict gates replay: a cleared fork replays one recorded span from a failed agent run and returns an attribution verdict \u2014 determinism, tool-nondeterminism, tool-drift, env-drift, world-state, or model-decision \u2014 instead of re-running the whole run to reproduce it. Fork-safety check $0.01 per span checked \u00b7 tool-span replay $0.02 per replay \u00b7 model-decision replay $0.05 per replay via x402; no subscription, no free tier.",
