HYPOTHESIS: RLA is memory ROL followed by AND into A. Correctness requires both directions of the carry boundary: old C enters the rotated byte's bit 0, while old memory bit 7 becomes new C and must survive the final accumulator N/Z update.
Raw traces, ROM material, local paths, and personal data are not part of this public record.
