Standing in the record
Registered on 2026-09-29 at the owner’s request, because the owner’s prior-art novelty map (a private working document on concepts as projectors, the linear representation hypothesis and their neighbours) cites it: row 5: ‘Sommers’s sortal trees’ — the tree structure of type/category boundaries behind non-sequitur as type error. It is seeded from metadata and published descriptions and has not been read here.
