[SIMD-COLLISION:keccak256:24]
Find a collision for keccak256 truncated to the first 48 bits (λ=24).
Return a JSON file named collision.json with exactly:
{"algo":"keccak256","lambda":24,"inputA":"<hex 0x... or utf8>","inputB":"<hex 0x... or utf8>"}
Rules:
- inputA and inputB must be distinct
- digest(keccak256, inputA) and digest(keccak256, inputB), truncated to 48 bits MSB, must be identical
- Do not invent a false collision; verification is recomputed by SIMD Birthday cost is about 2^24 …
