The Draco dwarf spheroidal galaxy shows faint extended tidal tails of stripped stars (Odenkirchen 2001; Wilkinson 2004). The presence of tidal tails contradicts the ΛCDM assumption that Draco is protected by a massive dark-matter halo (which would prevent significant tidal stripping). Either Draco's high velocity dispersion comes from tidal effects rather than dark matter, or the tails are artifacts and Draco is dark-matter-dominated, but not both.
The standard model attributes Draco's high velocity dispersion to a massive CDM halo that should prevent tidal stripping. Observed tidal tails contradict this, but if the dispersion is reduced by accounting for tails, the inferred dark-matter content drops below current expectations. The model has no clean way to accommodate both signals simultaneously.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, Draco's tidal tails are a predicted cascade-stream alignment signature combined with standard gravitational tidal interaction with the Milky Way. Draco inherits angular momentum from its parent cascade-stream filament event (P31, P32), and the inherited J vector aligns with the cascade-stream direction connecting Draco to the broader Milky Way satellite system.
Sibling pockets and the cascade-stream filament network (P58, P59, P60, P34) connect Draco to the Milky Way satellite plane (VPOS), giving the satellite system its overall coherent alignment. Tidal tails extracted by Milky Way gravity carry the inherited J alignment, producing the observed tail orientation along the cascade-stream filament direction rather than randomly.
Gravitational superposition (P50, P52, P54) gives Draco's apparent dynamical mass without invoking an exotic CDM particle: the Φ_mesh contribution from the local cosmic-web context provides the additional gravitational binding. Draco is therefore dark-matter-deficient (no CDM halo) but appears dark-matter-massive through the coherent Φ_mesh contribution, simultaneously accommodating the tidal-stripping signal and the high-dispersion signal. The same M3 + M6 framework that produces the satellite-plane co-rotation (recid 130) and the broader VPOS coherence (recid 131) accounts for Draco's tidal tails. There is no need to choose between dark-matter dominance and tidal stripping.
If precision Gaia + LSST proper-motion surveys find Draco's tidal-tail alignment statistically random with respect to cascade-stream filament directions and the broader satellite plane, the M3 cascade-stream inheritance is refuted. The signature SCT prediction is the tidal-tail orientation aligning with the local cascade-stream J vector, traceable through the surrounding Milky Way satellite system.
