Connectedness‑Modulated Extra Acceleration (CM‑EA): A Falsifiable Inner–Outer Radial Test for Dark‑Matter‑Like Galaxy Dynamics in Disturbed Systems

This deposit contains the preprint “Connectedness‑Modulated Extra Acceleration (CM‑EA)”. CM‑EA is a falsifiable, within‑galaxy test designed to distinguish a “no suppression” benchmark from a scenario in which a MOND‑like extra‑acceleration component is reduced in kinematically disturbed/weakly connected spiral‑arm or tidal material. The paper defines an operational analysis pipeline, pre‑registered inner/outer regions, gatekeeping criteria, null tests, and mock‑recovery checks, and summarizes outcomes with an inner–outer ratio statistic.
