Voids a draft or issued invoice — the cancel. It is the org admin's act; a
member is refused 403.

A paid invoice cannot be voided: money has moved, and the correction for that
is a refund, not an erasure. The state machine refuses it and that refusal is
the answer.

A named handler, not a closure, so zipdoc can lift this prose into the registry.
