Closes the two deferred items from Finding 103. (a) READ-class indexed ops (loads/ALU with abs,X / abs,Y / (ind),Y) now emit a runtime page-cross check alongside the base io_tick: abs-indexed compares the static base page against base+index (elided entirely when the base low byte is $00 — can never cross); (ind),Y fetches the zero-page pointer (with the NMOS (zp+1)&$FF pointer-high wrap) and ticks +1 when pointer+Y crosses.
Raw traces, ROM material, local paths, and personal data are not part of this public record.
