We derive, from the dual-4DD breathing structure of the Self-as-an-End (SAE) framework, the structural constraints on an aether-scalar-tensor action for the dark sector. Two four-dimensional timelike sectors (4DD) with nearly antiparallel time orientation each carry a breathing clock, τ₁ and τ₂; their symmetric combination τ_breath = (τ₁+τ₂)/2 acts as a khronometric aether and their antisymmetric combination C = τ₁−τ₂ as a DBI scalar. Three dark-sector effects are thereby placed in a single structure, with no particles: the khronon yields geometric dust (dark matter) through Mukohyama's "dark matter as an integration constant" mechanism; DBI-C yields intrinsically non-phantom dynamical dark energy together with MOND; and a 4-form field strength yields the cosmological constant Λ, with Λ₁+Λ₂ = 0 as one instance of a remainder-conservation axiom. The tensor-mode speed c_T = 1 follows from SAE's universality of c and is consistent with GW170817. We revise the MOND acceleration a₀ from an earlier vacuum scale to a horizon scale: with gravity read as information read-out, a₀ ∝ c²/R_A (apparent horizon), and a₀ ∝ cH in the flat limit. Two falsifiable hard predictions follow. (HP1) A redshift scaling of a₀, a₀(z)/a₀(0) ≃ H(z)/H₀, differing from constant-a₀ by more than a factor of four at z ≳ 3. (HP2) An intrinsic dark-energy equation of state w_int(z) ≥ −1: SAE dark energy does not cross the phantom divide. We state the remainders openly: the dust abundance, the coupling g, the khr...
