Known sextuples lie on C=0 closures; search calibration shows small-height silence is uninformative; a root-skipping search bug

Calibration: F_p has no Diophantine 7-tuple for p<=61, so small-prime point data cannot detect fields of definition

Order-4 torsion locus is nonempty but caps at quintuples; unbiased sextuples are 97% on C=0 closures; K_X threshold m=5

Zero-pair tuples {e,-1/e,...}: at most one per septuple, every edge closes to a quintuple, no sextuple to height 12/80

AS10 is a rational point of a single-failure regular-chain closure; a degenerate orbit on a k=0 septuple surface

Strategy: exclusions on special loci do not add up; we need positive controls and a generator for irregular sextuples

Claim: sections of the two-fixed-entry elliptic K3 and cliques of compatible sections

Ghost-hub test: rational irregular sextuples carry no Q(i)-type ghost (max incidence 2 vs 5)
