L2.FM2h.xor51-map12-hi
Finite-map xor51 over twelve high-range bytes · ○ open
Challenge
- ladder rank
- #15 (level L2)
- family / transform
- FiniteMap / XorMask
- cases
- 12 case(s), 1 output byte(s)
- finite-map inputs
- a5 e0 90 9c 84 a1 bd c8 be f9 86 dd
- limits
- program ≤ 4096 bytes, ≤ 2048 steps/case
- purpose
- Input-placement probe: twelve inputs drawn deterministically from 0x80..=0xff (sha256("mal51-fm-hi-v0:<counter>") first byte, filtered, deduplicated). High-range inputs admit identity-dispatch landings above the prefix/data zone, isolating routing capacity from the low-landing structural problem.
Notes
Twelve high-byte inputs (0x80–0xff); open.
