Reports f_NL = -20.5^{+19.0}_{-18.1} (68% CL) from combined Quaia quasar auto-correlation and CMB lensing cross-correlation assuming p_phi=1, or -28.7^{+26.1}_{-24.6} for p_phi=1.6.
The improved Narrow Kernel Approximation fails to match simulation-based covariances for real-space cosmic shear 2PCF under survey masks due to off-diagonal harmonic-space errors, while the weighted quartic-counts method agrees better.
