identity property
The pool's identity as a descriptor publishes it, read off the issuance's own PP1 through the body check.
Implementation
late final PP1Fields identity = (() {
final (fields, why) = PoolEvidence.readPP1Of(r0, PoolEvidence.pp1Vout);
if (fields == null) throw StateError('the issuance carries no PP1_SP ($why)');
return fields;
})();
