Concern: iter 46 attributed the 271-frame exit to "$E3/$E4 = 0 after ZP-clear at $106B-$106E". Iter 47 adds a $E3/$E4/$E5/$E6 write trace (windowed at frames 0-2 / 190-210 / 260-280) to confirm whether/when these pointers get set.
Raw traces, ROM material, local paths, and personal data are not part of this public record.
