INDEXED-INDIRECT READS WRAP BOTH POINTER ACCESSES IN ZERO PAGE

MOS manual section 6.10, Example 6.10 diagrams the fixed indexed-indirect schedule: fetch opcode and BAL, read and discard $00,BAL while adding X, read ADL from $00,(BAL+X), read ADH from $00,(BAL+X+1), then read the operand from ADH,ADL. The manual explicitly says cycles three and four are confined to zero page and cannot carry into the next page; the pointer-high increment is likewise byte-wrapped by the processor sequence.

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