GAIP Software agents act for people: they buy, book, cancel, agree, deliver, refuse, tell, ask, read and check. Each payment rail, marketplace and assistant keeps its own record of those acts, held by that party. The person the agent acted for has no record of their own. This document describes the Agent Act Receipt: one entry per act, written by the agent as digests bound to a continuity handle, signed by a running transparency service, placed in a hash chain and covered by dated anchors, with a COSE_Sign1 form of the signature and a signed export (the switch pack) the person can take to another agent. The format is published by GAIP, which runs one such service. This document makes no claim of trust, certification or adoption: a receipt shows that the service's key signed a digest at a stated time, and nothing about the act itself.
