We present the Anchor Collapse Model (ACM), a holographically motivated framework for galactic dynamics built on the collapse-limited coherence of the cosmological background field. Unlike Modified Newtonian Dynamics (MOND) or dark-matter halo models, ACM does not begin from an empirical acceleration threshold or an additional unseen mass component. Instead, it treats gravitation as an emergent compensatory flow of the background potential, arising from phase-locking between baryonic anchors and the cosmological background field. In this picture, the effective coherence length, Leff, is anchored to the cosmological horizon scale c/H0, which sets the propagation range of background collapse support. Flat galactic rotation curves then emerge not from additional mass, but from the persistence of long-range holographic coherence in low-density, high-transparency regimes, where baryonic self-shielding becomes weaker and the background field is more freely released. Using a rigid global backbone equation with no galaxy-by-galaxy parameter tuning, we show that ACM reproduces the observed Radial Acceleration Relation (RAR) across the SPARC sample in a unified way while reducing the matched-sample median chi²ₚt from 39. 88 for fixed-a0 MOND to 23. 78. In a deterministic non-anchor holdout test, the retained trunk also outperforms MOND on 9 of 12 galaxies. This paper establishes the theoretical foundation of ACM and motivates a broader program in which local galactic dynamics and cosmic expansion are interpreted as coupled manifestations of holographic information damping.
