The review found that each try at an unready channel composed its held messages and so made a Details
ticket for each, and enough tries pushed out the tickets of messages already shown.
A newer message about the same problem (an escalation, a reminder, a re-send) replaced the Details
ticket of the one before it on that channel kind, so tapping Details on any but the newest was refused
"it belongs to no open message". Each message now keeps a ticket of its own, used once, at most
MostDetails per record and kind and none older than TokenFor; one pushed out is refused in words that
send the operator to the newest message. A change of the condition's actions no longer drops Details,
which names no action.
