One claim: the galactic acceleration scale is set by the dark-energy density.

Owner decision 2026-10-31: the a₀ floor is removed from route E’s core rule. Working rule: S_cold = f_c η Σ_coll with native η, no floor; a₀ no longer enters the halos. Native N passes the SPARC line, and falls short on LITTLE THINGS. See OWNER_DECISION_2026-10-31_NO_FLOOR.md. Text below that states the floor predates this.

Checkpoint 2026-10-29 (route E, the owner’s 25 October flagship: the a₀ law plus the cold dark energy core law). This is not a new verdict on v3s, which stays frozen.

• The core rule is ρ₀r₀ = max(a₀/2πG, η Σ_coll). It is empirical: every mechanism tried for the floor is closed (X47, X65–X68, the phantom-halo ceiling, pressure floors, correlated matter beyond r_ta; see rebuild_2026_10_22/X65_X67_POSTMORTEM.md). SPARC prefers the hard floor (X69_soft_floor_sparc: softening it worsens the low-acceleration half by…
