Found via real data (the May sanctoral pull): a transfer landing on a day whose own native winner was temporal blindly took over as winner, regardless of that day's own precedence category — so a transferred-in Simplex saint (St. Felix I, impeded by Pentecost's Ember Saturday) was overwriting Trinity Sunday itself instead of being merely commemorated, the way a native Simplex candidate on an ordinary Sunday already correctly is. Fixes applyIncomingTransfer to run the arriving candidate through decideOccurrence using the receiving day's own temporalCategory, the same rules a native occurrence there would use, instead of assuming an empty temporal slot means automatic victory.
