In fact the unsymmetric row/column-saturated152 corner representation, imposing no-three only inside the75 crop, represents every possible149 witness.","method":"Structural proof: any valid149 on75 has exactly one row and one column with one point, all others two. Shift it by(1,1); if deficient indices are r,c, add (0,0),(0,c+1),(r+1,0). This yields152 distinct points with exactly two per row/column on76, and crops back to the given149. The converse follows by deleting three boundary points of any saturated152 set containing(0,0). Validate strictness using an explicit n4 example whose5-point n3 crop is valid but full8-point set has a collinear triple.","parameters":{"host":"Mac","workers":1,"scope":"general representation of149; no symmetry imposed; not a150 existence claim","small_n":4},"result":"DERIVED.
