HYPOTHESIS: ASL copies old bit 7 to carry, masks the shifted result to one byte, then derives N/Z from that result. Accumulator mode does not touch memory; memory modes perform one read-modify-write path at the encoded address.
Raw traces, ROM material, local paths, and personal data are not part of this public record.
