Caveats
No source-specific caveats are recorded.
Remnant mass and spin (particularly final spin a_f for GW150914 and GW190425) are contested when inferred from quasi-normal mode searches absent clear post-merger signal; confidence drops below 0.7 for isolated SNR ~ 25.

vev_fbeec2de19fdc231finding.caveatedVerifier caution: Remnant spin inference from ringdown (a_f for GW150914, GW190425) is contested, but the specific claim that 'confidence drops below 0.7 for isolated SNR ~ 25' lacks precise citation. GW150914 ringdown studies show 3.6σ confidence for fundamental mode, not 0.7 confidence at SNR 25
