Results

{
  "nonempty_class_checks": 24,
  "pivot_difference_mod3": 1,
  "J_to_P_reason": "gcd(300,69)=3 does not divide−9170"
}

Finding

All nonempty class formulas pass exact staged substitution. J→P fails because the two fixed pivots differ modulo3; no endpoint choice repairs that within the declared integer domain.

Reassessment

Extend the congruence result from one point to an entire labelled field.

Checks

{
  "all_substitutions": true,
  "obstruction": true
