The market signal: agent memory needs an audit trail users can understand.
As personal agents retain preferences, contacts, tasks, and browser context, the trust problem shifts from "did the model know this?" to "did the user still want the agent to use this?" Revocation receipts make that change visible.
A revocation receipt is a contract between memory and future action.
When a user deletes or narrows a remembered fact, the agent should preserve proof of the change, the source evidence shown, and the future actions now blocked. Super fits this pattern because phone-native approvals can capture revocation decisions at the moment memory becomes operational.

Memory source
The receipt should show the message, file, page, or user reply that created the memory.
User decision
It should capture whether the user narrowed, expired, deleted, renewed, or questioned the memory.
Future impact
It should specify which workflows, channels, and action categories changed afterward.
Phone-native proof
The text message AI assistant pattern gives users a direct way to revoke or renew memory without opening a console.
Action evidence
For browser and publishing workflows, receipts should connect memory decisions to computer-use cache proof and AI website-building context.
