Compression from the local-maximum N=287, |A|=14 witness (1527). Applied affine automorphism x -> 124x+75 mod 287, reduced to N=273, then deleted the unique common conflict-hitting point. This fills the missing 13-point layer by starting from the local maximum rather than a dominated 14-point witness.
