Temporary computation PR targeting the only stated GRH dependency in Freitas--Naskręcki--Stoll's classification of primitive solutions to x^2+y^3=z^11.

For each of the five degree-12 fields attached to 54a1, 96a1, 864a1, 864b1, and 864c1, the workflow forms the degree-36 compositum with the cubic 2-division field theta^3-4 theta^2-160 theta-1264, verifies the degree, certifies the maximal order with PARI nfcertify, computes the class group and units, and requires both bnfcertify(B,1)=1 and full bnfcertify(B)=1.

A successful artifact would remove the computational GRH assumption for that field. Failed, timed-out, or partial jobs prove nothing and retain their logs. This PR itself makes no unconditional Diophantine claim.
