// One answer to "is this QSL received".
//
// ADIF's QSL_Rcvd enumeration has BOTH Y and V: Y is "received", V is
// "verified" — and V is what a LoTW download writes for a confirmation the ARRL
// has validated. Testing for 'Y' alone therefore misses exactly the
// confirmations an operator cares most about.
//
// It showed on screen: the Awards panel had Morocco validated on five bands
// while the band/mode matrix beside it showed the entity as merely worked. The
// award engine accepted Y or V; every other test in the app accepted Y.
//
// The Go side has the same rule twice over — award.isYes and qso.ConfirmedValues
// — and all three have to agree. If you add a value here, add it there.
