act property
Act is the durable, opt-in grant that lets this key act FOR a user in its own org — the credential behind as(): presenting it authorizes minting a short-lived, user-bound token for a member of the key's tenant. Default false, so a server key mints nothing on anyone's behalf until the grant is set deliberately — the capability is never inherited by every key. It is confined at mint time to the key's OWN Owner, and a reserved-org or SuperAdmin target is refused, so the grant reaches only ordinary members of the one tenant that holds the key.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
bool? act;
