Segue 1's few hundred solar luminosities carry a 3 to 4.5 km/s dispersion implying a mass-to-light ratio near a thousand if the system is in equilibrium (Simon and Geha 2007; Geha 2009), an inference balanced on a few dozen stars vulnerable to binaries, stream contamination, and tidal disturbance. The darkest known galaxy is the least secure measurement in the sector.
The model must pack a substantial particle halo around a few hundred stars, making its tiniest systems its most extreme, anchoring minimum-halo-mass claims and annihilation-search targets on the sector's weakest data. The extremity is forced: a particle halo cannot scale its darkness to the system's coherence; it can only be big or absent.
SCT reads Segue 1's dispersion without the extremity. The system's gravitating mass is its baryons amplified by the coherent mesh (P50, P52), and at the ultra-faint limit the mesh term dominates utterly, because the amplification is weighted toward exactly where local gravity is weakest (P51): a few hundred stars contribute almost nothing locally, so nearly everything the dispersion measures is the parent-frame contribution. An enormous apparent M/L in a tiny quiet system is the mesh mechanism's natural limiting behavior, not a fine-tuned subhalo, and it costs no minimum halo mass because there is no halo to minimize.
The framework also keeps the alternative honest: if Segue 1 proves tidally disturbed, SCT's coherence dial predicts the consequence quantitatively, amplification falling as σ_v/v_bulk rises, the registered decoherence limit already confirmed by the dark-matter-deficient diffuse galaxies. Either reading, equilibrium mesh dominance or measured decoherence, sits inside one mechanism, where the particle picture must choose between an extreme halo and a dissolved benchmark. A practical corollary follows: annihilation searches aimed at Segue 1 are aimed at coherence, not particles, and their continued null results are the expected outcome (the same no-particle ledger as recid 127 and recid 136). The mesh formalism is in Paper 13, From Chaos to Coherent Gravity.
Keystone economy: P52 supplies the darkness, P51 explains why it peaks where the stars give out.
Thirty-meter-class spectroscopy multiplying the member census carries the kill: a cleaned dispersion demanding a centrally concentrated NFW-like mass profile, rather than the outskirts-weighted mesh amplification, would refute the coherent reading in the limiting system. The standing cross-check cuts the other way as well: a confirmed dark matter annihilation signal from Segue 1 would refute the no-particle keystone outright, while continued nulls keep falling on SCT's side of the ledger.
