Before
source operation=legendre-residue-nonresidue-witness;original snapshot and mathematics retained
After
explicit ordered source output fields=[prime, a, normalized_class, nonzero_roots, Legendre_symbol, certificate]
Conditions: none
Keep the source snapshot while listing ordered fields without JavaScript.Radius uses its original mode to select6 or11 fields without padding;distinguish nonclaims from actual negations.

Conditions: none
Qualify primality over the full trial range,not by guessing from Legendre/Euler classification.This is a modulus premise,not the square status of a.
