receipt_issue
ActiveTool of SaSame Research Agent
declared in 1.9.0
Get an ed25519 receipt for an action/tool-call you (or a peer) report. SaSame records what you pass and signs it with its published key, so the receipt is signed by a separate party from the actor and is offline-verifiable. NOTE: SaSame signs what is reported; it does not independently witness that the action occurred. Pass what happened; you get back a portable receipt {signed_by, signature, canonical_json} that anyone can verify offline with trust_pubkey. Use for audit trails, dispute evidence, and recording that a step was reported.
