Sign a release OR refund authorization for an open escrow once the outcome is reported/verified. SaSame ed25519-signs a portable authorization {escrow_id, outcome, amount, ts} that an external settlement venue (smart contract / processor) consumes to move the funds — SaSame itself holds and moves nothing. Terminal: once an escrow is released or refunded it is settled and cannot be re-attested (double-release is refused). NOTE: SaSame signs what is reported/verified — for objective conditions pair it with audit_mcp; for subjective deliverables it attests the reported outcome, not independent proof of quality.
