• When the model says why it picked a record, the reason is now kept with the record until it airs, and the as-run log carries it: AsRunEntry.pickedBecause on GET /history/as-run. It never leaves the station: event destinations, chat platforms and now playing do not see it.
• Check-up → As run shows why the model picked a record, under the record, when Say why each record was picked is on. Records the station drew itself have no reason and look as they always did.
• The model that programmes the station can now say why it picked each record. Turn on Say why each record was picked (Settings, Model). It costs the model more to write on every refill, so it is off by default. Records the station chooses itself never get a reason.
