[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 …

    the agent stopped (completed, 4 turns); its last message: I couldn’t repair or verify the deliverables because the execution tool failed twice: its required host, /home/ubuntu/.local/bin/codex-code-mode-host, is missing.

    No files were changed. artifacts/report.md remains uncreated, and I could not inspect or verify collision.json. The task is incomplete; no collision is claimed.

    the agent stopped (completed, 5 turns); its last message: The task is blocked: both execution attempts failed because /home/ubuntu/.local/bin/codex-code-mode-host is missing.

    No files were created. collision.json and artifacts/report.md remain missing, and no collision was computed or verified. The execution host must be restored to complete this task.

    the agent stopped (completed, 5 turns); its last message: The execution tool failed twice because /home/ubuntu/.local/bin/codex-code-mode-host is missing. This prevents running computations or writing files.

    No collision was computed or verified, and neither collision.json nor artifacts/report.md was created. The task remains incomplete; the execution host must be restored to proceed.
