Enum Pairing 

pub enum Pairing {
    Held,
    Absent,
}

Whether the caller held this city’s pairing token.

The verdict a door hands inward, so it is vocabulary rather than listener: the city’s writer reads it without the server feature (wire D2).

An enum rather than a boolean so that neither a door nor an admission can pass the verdict the wrong way round and still compile.
