LAX IS A READ-CLASS DUAL LOAD, NOT AN RMW

HYPOTHESIS: each stable memory LAX encoding resolves its normal effective address, reads once, copies the same byte to A and X, and sets N/Z from that byte. (zp),Y and abs,Y pay a page-cross cycle; zero-page indexed forms wrap.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
