P 41- V1.3 - The GWTC-4.0 Catalog Reveals 21 Objects GR Cannot Explain — CCEGA Can

v1. 3: Updated phase boundaries Mmax = 4. 56 M☉ (P34 v2. 0), Mcrit = 12. 0 M☉ (P36 v2. 0). Note Added addresses catalog variance limitations following Corelli et al. arXiv: 2603. 00239. Analysis of all 369 gravitational wave events in GWTC-4. 0 O4a. 21 events (5. 7%) populate the CCEGA intermediate regime (2. 33–9. 20 M☉). Statistically significant differences from true black holes in spin (p<0. 0001), total mass (p<0. 0001), and mass ratio (p<0. 0001). GW190814 and GW230529 consistent with CCEGA ultracompact objects. Circumstantial evidence — not confirmation. Definitive tests: NICER tidal deformability (2029), Einstein Telescope echoes (2035+). Mₘax boundary carries uncertainty (P29 v1. 1, P34 v1. 1).
