Material: Candidate answer and counting hint
Match strength: Strong near-match—the standard three-cube compound rather than a proof over every possible configuration
Status: Proposed/disputed. The answer relies on a cited cell count and does not prove maximality; a comment also raises an interior-versus-exterior counting convention.
