Cancel a mandate (ALPHA)
Alpha — early access.
Revokes a pending or active mandate — every version of it at once; there is no way to cancel one version and leave another in force. The canceller must be a recognized signer OTHER than the bound one, with a valid signature over the mandate payload — the bound signer can never mutate its own mandate (§8 applies to every mutation, including authority-reducing ones).

Response
Mandate terminated — rejected if it was still pending, revoked if it was active.
Scheduled payments are NOT cancelled. They are signer-scoped and decoupled from mandate lifecycle, so any payment this mandate was covering stays scheduled and then FAILS at its due date, when the executor finds no mandate authorizing it. Cancel those payments explicitly if they should not remain on the customer's schedule.
pending, active, rejected, revoked, done The signer that cancelled the mandate while it was still pending (§8); absent otherwise.
The signer that cancelled the mandate after activation (§8); absent otherwise.
