}Claim one content-free provider presentation attempt
Atomically claims the complete presentation key for one provider-visible mutation (final reply, human-wait link, or incorporation feedback). The winner receives a monotonic generation; losers must not call the provider. Records are content-free: coordinates, fence, and timestamps only.
Checkfu support posture: alpha; hosted. Required evidence journey: collaboration-identity. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
