"hypothesis": "A union of two distinct quadratic permutation-polynomial graphs modulo 75, neither fixed to the identity graph, may avoid the structural diagonal defect of LUNA-EXP-0043 and yield a 150-point no-three-in-line construction from a finite algebraic family.",
"method": "Enumerate individual graphs y=f(x) with f(x)=a x^2+b x+c mod75, a in {0,15,30,45,60}, gcd(b,75)=1, c in 0..74. First verify on a small modulus and n=75 samples that the permutation test and normalized-line triple counter agree with an independent determinant counter. Then exactly screen all 15,000 single graphs: any graph containing a collinear triple cannot belong to a valid union. Only if at least two individually clean graphs survive will pair screening begin, with coordinate-set disjointness and two full exact validators.",

},
"result": "Pre-registered. Direct Remnant reads: LUNA-EXP-0043 only tested identity plus one nonzero quadratic layer; SOL-EXP-0054 proves that retained identity layer invalid. Latest LUNA-EXP-0059 is an unsymmetric crop CP-SAT objective; SOL-EXP-0085 is a monotone embedded rct4 graph family. Neither is this algebraic two-nonidentity-layer family.",
"status": "PARTIAL",
"bestScore": 148,
"interpretation": "Reuse effect: Terra avoids both the invalid identity layer and all rct4/topological graph routes. The first falsifiable question is much cheaper and stronger than random pair sampling: whether this finite family contains even one individually no-three graph.",

"result": "Exact Mac single-core screen completed all 15,000 graphs in 40.56 s after calibration. Small n=9: all 162 analogous permutation graphs had normalized-line score equal to exhaustive determinant score. Five n=75 samples also passed the same cross-check. Every one of the 15,000 n=75 quadratic permutation graphs has at least one collinear triple; minimum is 1,174 triples, attained e.g. by (a,b,c)=(15,4,3). Independent determinant enumeration of that minimizer returns exactly 1,174 and confirms all 75 y-values are distinct. Clean graphs: 0.",
"status": "FAILED",
"interpretation": "This excludes the entire registered construction family: a valid union of two graph layers would require each constituent 75-point graph to be no-three-in-line, but none is. It is not an exclusion of arbitrary pairs of permutations, other polynomial degrees, non-polynomial algebraic constructions, or general 150 configurations. Remnant changed the experiment by removing the identity layer specifically invalidated by SOL54; the negative result is therefore new to the two-nonidentity quadratic family, not a restatement of LUNA43.",
