MAV-MCC GW250114 Provenance and Convergence Note v0.1 — Post-Merger Horizon Residuals, O4b Domain Relevance, and Acknowledgement Clarification

This package records a conservative provenance and methodological-convergence note linking the MAV-MCC relativistic evidence packages frozen on 2026-03-18 with the later Nature publication “GW250114 reveals signatures of post-merger black-hole horizon” published on 2026-06-24. The note makes no misappropriation claim and no ex-ante direct-wave claim. It documents that MAV-MCC had an archived gravitational-wave branch before the Nature publication, including relativistic anchors, an O4b blind protocol, anti-leakage discipline, and residual/boundary-oriented interpretation. The Nature/GW250114 result is treated as an external convergence toward post-merger near-horizon residual analysis. The publication is intended to preserve provenance, clarify chronology, and support a non-adversarial acknowledgement/provenance clarification with the Nature authors. b1927a41759325c4e31fb077518985509ff40c2e60310f588548a781f74713b1
