Burst-oscillation pulse-profile measurement
The argument
Because pulse profile modeling of the source's thermonuclear burst oscillations yields a radius near 7 km at about 1.2 solar masses, and given that standard nuclear-matter equations of state predict radii of about 11 to 13 km at that mass, the inferred radius falls well below what conventional neutron star models predict.

The inference is straightforward: if the burst-oscillation analysis yields about 7 km and standard models predict 11 to 13 km at that mass, the inferred radius falls well below prediction. The measurement premise, that pulse profile modeling yields a radius near 7 km at about 1.2 solar masses, is verified against the primary source. The remaining weight rests on the 11 to 13 km prediction range, which is not yet assessed but matches the broad consensus from independent radius measurements and is disputed by no source found.
