One operation. One evidence envelope.

What Kestrel refuses to overstate
No hash, no settlement claim.Submitted and confirmed remain separate terminal states.
No policy grant, no server execution.The signer accepts only an unexpired HMAC-bound authorization.
No hidden fee.Kestrel, Arc, Gateway, provider, forwarding and gas deductions stay distinct.
