What the receipt contains
Stable task and request IDs, the policy version, requested fields, released and withheld fields, reads used, destination and memory policy.
Privacy receipts for agent tasks
A privacy receipt records what was requested, what policy decided and what the agent actually received.
What it does not prove
A receipt is evidence from this experiment. It is not an external audit, certification or guarantee that every possible implementation is secure.
Why the receipt is useful
Owners can compare the task result with the exact access path instead of trusting a vague statement that the agent respected privacy.
