A real record from their export settles it:
<CALL:4>RL6M … <CNTY:5>RO-19 <APP_HAMLOG_R150COUNTRY:6>Russia
<APP_HAMLOG_QSO_CFM:1>Y
The confirmation lives in APP_HAMLOG_QSO_CFM. The four names guessed before a
file was available — APP_HAMLOG_QSL and friends — were all wrong, which is the
argument for reading one rather than reasoning about it.
So that becomes the canonical key everywhere: the award source, the row colours,
the grid column and the bulk editor. Importing a log downloaded from HAMLOG now
carries its confirmations into OpsLog with nothing to rename. The older names,
including the APP_OPSLOG_HAMLOG_QSL that OpsLog itself wrote in the meantime,
are still honoured on read so nothing already stamped stops counting.
