Modern cosmology describes expansion, the dark sector and large-scale structure under a single roof; yet the microphysical origin of these components, the initial singularity, blackhole centres and the direction of the cosmic cycle remain open. This article presents the main text of the ΨD (Dimensional Flow Cosmology) framework: at the foundation of the universe lies not a continuous field but countable, indivisible existence nodes at the Planck scale (planckons); matter, energy, network and volume are organizations of these nodes across the phase degrees d0–d3. The entire structure is carried on a single ledger: E(d) = (d+1)εP, U(d) = (3−d)εP, E+U = 4εP — the d-dependence follows necessarily from threedimensional direction counting. Six main results are established. (i) Expansion is not a push but the spending of a finite potential across five channels (phase, volume, network, radiation, transition) by equipartition; the equipartition αi = βi = 1/5 is derived from channel indistinguishability (maximum entropy). (ii) The form, exponents and amplitude of the driver follow from the ledger: (a″/a)drv = Ωs·A³(1−A), where p = 3 is the signature of three-dimensional volume counting and q = 1 of ledger linearity; the amplitude is read from the work budget, Ωs = 20·Wvol,max = 11.41, and the zero-parameter set predicts ztr = 0.69, q0 = −0.45, w(today) = −0.90. (iii) The restorative network potential Unet = W·A² is derived from affine stretching; with the gate (A³)² = A⁶ the effective force is Fnet,eff = −2W·A⁷; since the gated network can capture only one quarter of the expansive work, the turnaround must be thermal, and the expansion upper bound is amax ≤ 1.46. (iv) A black hole is a local Big Crunch: the core radius is r1 ∝ M1/3; since the formal threshold μ ≈ 0.17 is sub-Planckian, it cannot be realized at any astrophysical mass — non-explosiveness is a geometric theorem; the horizon entropy is S = A/4ℓP², the 1/4 coefficient follows from the ledger’s hidden-share ratio U(d2)/4εP, and it yields the Hawking temperature without tuning. (v) The 10−122 smallness of the cosmological constant is not fine-tuning but a counter reading: χΛ = (ℓP/RH)² = (H0tP)² ≈ 1.39×10−122. (vi) The quantum core is partially closed: E = ħω is a canonical theorem, the Tsirelson bound S ≤ 2√2 follows from the Landau identity, the Born rule from Gleason’s theorem, and the coherence of pair creation from the single-bond event. The observational comparison is carried out primarily with the canonical CPL set (w0 = −0.844, wa = −0.219): the DESI DR2 pure-shape BAO test computed first-hand in this work (13 components, covariance with within-tracer correlations; Ωm profiled) gives χ² ≈ 8.86 for this set, beating flat ΛCDM (χ² ≈ 10.56), and yields q0 ≈ −0.386. The internal d0/d1 split of the dark sector is treated in the companion paper and closed there: the internal-share reading 0.85 is no longer a free number — the exact solution of the freezing kinetics (threeaxis folding binomial), with the zero-parameter halt-scale input, derives Nd0/Nd1 = 0.861 (deviation 1.3%); the unified-cycle paper also derives the sector fraction from hot-end saturation: Ωfree = 1 − e−3 ≈ 0.9502 (deviation 0.08%). The present text carries the total ledger of the free pool and the cycle dynamics. Appendix H closes the remaining N and O items with nine new propositions (Propositions 27–35) from the two locked principles: the Bekenstein–Hawking 1/4 coefficient is derived with the exact coefficient from foldedhorizon phase counting (the unfolded geometry gives 1/8), and the cosmic budget closes with no free numbers — ΩΛ = 0.6850 (Planck 0.6847; deviation 0.05%), Ωm = 0.3150 (deviation 0.1%). All epistemic statuses are collected in a single table (Section 13).
