What changed
Early personal agents could rely on a prompt and a conversation transcript. Execution-focused agents need a more durable permission chain. A consent receipt captures evidence, scope, excluded actions, expiry, and rollback. The audit log captures planner steps, tool calls, outputs, and errors. When joined, the system can answer both questions: was this allowed, and what happened?
For a text message AI assistant, the approval can remain lightweight while the receipt id anchors the full execution trail.
