L2.R0d.xor-1-len4096

Xor one byte with 4096-byte program cap · ○ open

Challenge

ladder rank

#24 (level L2)

family / transform

Transform / XorMask

cases

1 case(s), 1 output byte(s)

limits

program ≤ 4096 bytes, ≤ 2048 steps/case

purpose

Same v0 xor-mask task as L2.R0.xor-1, with only the program-length cap relaxed for calibration.

Notes

General XOR with a 4096-byte cap; best known coverage 27/256.

xor-1 with the length cap relaxed to 4096 bytes. Attempts here established identity dispatch — byte 121, all-1 trits, is loader-valid only at cells 35 and 41, reached through MOVD pointers — and a shared station with per-lane pointer cells, verified at 27/256. Ceilings measured along the way: MOVD pointers are printable bytes ≤126, confining operand freedom to a ~96-cell pool good for about 30 lanes; three-CRAZY chains reach 81 of 256 values; no per-trit map puts more than 41 of 256 XOR outputs in the dispatch itself.
