The Dark Sector over Finite Substrate

Galaxy dynamics and the accelerating expansion are the two standing tensions of large-scale gravitation. We develop both from one finite relational substrate on which gravitation is the synchronisation of elementary clocks. Synchronisation reproduces Newton’s law at high acceleration and carries an intrinsic resolution floor, fixed by the expansion rate, at $\az=c\Hzero/2\pi$, $13\%$ below the observed scale and within its systematic band, with no free parameter.

The construction’s dependency structure is collected here in one place, so that every result above can be traced to its inputs and the surface a reader must accept is made explicit. Each row carries one status: a single tag, or the defined compound T$\,\vert\,$R (a theorem evaluated on a declared realisation) or D$\,\vert\,$T (a definition with the theorem it carries), the parts separately citable. The blocks: A the inputs, B the eight realisations, C the derived rows, X what the construction explains (Section 8.1), P the falsifiable predictions (Section 8.2), V the machine verification, Z the $\Om$-hard residue, O the conjectures stated ahead of derivation. The source column names the body statement and, for every machine-verified row, the family identifiers of the validation package (dark.flux_exact, dark.interpolation, …; one family per script, Appendix A), the package’s records citing the rows in return. The corpus master ledger carries B1 under its row 00:D3, B8, C4, C5 and C6 under its row 00:L1, C2 under its rows 00:L1 and 00:N2, P1 under its row 00:L7, P6 under its row 00:N1, and Z1 under its row 00:Z7.

B. Realisations: mathematics $\to$ physics (the forced identifications, each with its falsifier)
B1p32008Gravitation is the synchronisation of elementary clocks; distance is decoherence. Falsifier: a gravitating species supplying the galactic and cosmological abundance (§ 8), or entanglement induced off the Newtonian rate.R
§ 2.1
master: 00:D3
B2p32009Mass is winding rate, $E=hf$; an acceleration advances phase at the rate $g/c$. Falsifier: a knee that does not track $H(z)$ (P1), or a rest mass with no winding.R
§ 2.1, 2.3
B3p32010The acceleration floor is the phase-coherence threshold $g/c=\Hzero/2\pi$: the winding frequency reaches the drive’s cyclic frequency (one radian of phase per Hubble time). Falsifier: a measured floor off $c\Hzero/2\pi$ beyond the $H_0$ uncertainty, or a floor that is directional or density-dependent (P6).R
§ 2.3
B4p32011Below the floor the registered force is read as an amplitude in the conjugate chart, the conserved flux as a count. Falsifier: a sub-floor law other than the geometric mean $\sqrt{\gb\az}$ at $x\ll1$, e.g. the wide-binary knee failing P3.R
§ 3.1, 3.2
B5p32012The intrinsic scatter is the spread $\delta\alpha$ of the source’s collective phase, read through the chart angle; its identification with the disk’s dynamical temperature is the conjecture O2. Falsifier: an intrinsic scatter that does not follow $\tan\alpha(x)$, i.e. no rise into the deep regime at fixed $\delta\alpha$ (P2).R
§ 5.1
B6p32013The lensing enhancement is the coherence-weighted amplitude, following the bulk-coherent components. Falsifier: a merger lensing peak tracking the shocked gas; the cluster-core residual off the amplitude-sum form over the core’s composites is the exposure of the conjecture O1.R
§ 6.1
B7p32014The cosmological constant is the curvature of the wrapped finite chart. Falsifier: $w\neq-1$, or a negative or scale-varying $\Lambda$ (C11).R
§ 7.1
B8p32015The masking barrier is the coincidence amplitude: registration fails when the killed noise walk first traverses the signal’s amplitude $\sqrt x$ in the metric $\delta_A$ the floor rate induces, coefficient one. Falsifier: an approach to Newton departing from $1-e^{-\sqrt x}$ beyond the binned-RAR uncertainty (the simple rational form differs by up to $0.05$ in $\gobs/\gb$ at $\gb\approx5\az$), or a knee displaced from $c\Hzero/2\pi$ ($\kappa^{2}\neq1$). Present confrontation: the binned SPARC relation departs from $1-e^{-\sqrt x}$ by less than the bin scatter in every bin of $2<x<10$, the rational form disfavoured in $\chi^2$ (dark.rar_shape).R

X8p32034The cluster-core residual is referred to the coherent amplitude addition $\sqrt{N_{\mathrm{eff}}}$ over the core’s separately virialised composites, the one law that also gives the merger selection (C10); the quantitative closure, with $N_{\mathrm{eff}}$ uncomputed, is the conjecture O1.T
Eq. (12), § 6.2, O1; dark.cluster_coherent
1/1
X9p32035The cosmological constant is small, $\Lambda\sim1/\Om$, the curvature of the finite chart and a reading of the one cardinality rather than a mode-sum vacuum energy, so no $120$-order cancellation arises.T
§ 7.1
X10p32036The dark-matter and dark-energy scales coincide because both are readings of the one cardinality $\Om$, the floor $\az=c\Hzero/2\pi$ and the curvature $\Lambda\sim1/\Om$ fixed together.T

P. Falsifiable predictions (formerly D1, D3, D4, D7, D8; the body’s P-labels)
P1p32038The redshift law $\az(z)=cH(z)/2\pi$: the knee shifts and the Tully–Fisher zero-point evolves, $v_{\mathrm{flat}}\propto E(z)^{1/4}$ ($+7\%$, $+15\%$, $+31\%$ at $z=0.5,1,2$), parameter-free; shape resolvable, value in Z1. Falsifier: a high-$z$ knee away from $cH(z)/2\pi$, or a non-evolving Tully–Fisher zero-point.E
1/1
master: 00:L7
P2p32039The scatter is the two-variable form $\sigma=(2\tan\alpha/\ln10)\,\delta\alpha$, vanishing for cold high-$x$ systems and rising as $x^{-1/4}$; SPARC at fixed $\az$: intrinsic $0.038$ dex overall, $0.04$ at the knee, $0.13$ at $x\simeq0.02$, bounding $\delta\alpha\lesssim3.5^{\circ}$. Falsifier: a deep-regime intrinsic scatter that does not rise, or a measured collective spread the scatter does not track.E
§ 5.1, § 8.2; dark.rar_scatter, dark.predictions
2/2
P3p32040Wide binaries ($\gtrsim10$ kAU) follow $\gb/(1-e^{-\sqrt{x}})$ with the global $\az$ and the vector Galactic field $\gext\simeq1.8\az$: a $10$$30\%$ velocity enhancement ($12$$16\%$ at $10$$40$ kAU on the collinear estimate), the exponential knee distinct from Newtonian and rational forms. Falsifier: Newtonian wide-binary motion, or a knee of the wrong shape.E
1/1
P4p32041Pressure-supported systems (ellipticals, dSphs, UDGs) lie below the cold-disk relation by the coherence factor $\sqrt{w}$, $w=1/(1+(\sigma_v/v)^{2})$, by $0.05$$0.15$ dex for $\sigma_v/v=0.5$$1$, correlating with $\sigma_v/v$. Falsifier: pressure-supported systems on the cold-disk relation.E
1/1
P5p32042Coherence-state cluster gas: the X-ray gas gravitates only when bulk-coherent, contributing in a relaxed cluster ($C_{ij}\to1$) and dropping out of a merger ($C_{ij}\to0$), the lensing displacement growing with the shock Mach number; the quantitative core residual of the same law is the conjecture O1. Falsifier: a merger lensing peak tracking the shocked gas, or no relaxed-versus-merging difference.E
Eq. (12), § 8.2
P6p32043A global, isotropic scale and no dark substructure: the floor is the global drive rate, identical in every direction and environment once the external-field correction is made; no new dark-matter state and no dark subhaloes, so stream perturbations and the satellite abundance trace baryons alone. Falsifier: a directional or density dependence of $\az$ beyond the external-field effect, or stream gaps and substructure lensing with no baryonic counterpart.E

V. Machine verification
V1p32044The validation package finite-ring-space/src/32-dark: the twelve scripts and the figure script as written — dark.flux_exact, dark.born_exact, dark.firstpassage_finite, dark.meridian_walk, dark.deep_regime, dark.deep_regime_fp, dark.interpolation, dark.rar_shape, dark.deep_mond, dark.rar_scatter, dark.cluster_coherent, dark.predictions, dark.make_figures — run through one registry, one family per script, its micro-checks the script’s own verdict lines together with the registry’s predicates on the script’s namespace and output (nine scripts print without asserting; every headline numeral is pinned by a labelled check in darkcommon.py), each family naming the rows it witnesses; the notebook 32-dark-main.ipynb executes them in the browser and the driver run_all.py writes results.json.T
App. A; run_all
V2p32045The discipline, recorded per family as its kind: EXACT — exact rationals, $\Z[i]$ or $60$-digit identities, no tolerance in the verdict (the Gauss law, the amplitude identity, the first-passage law); SIM — a seeded stochastic simulation, verdict by stated tolerance (the noisy link, the killed walk); CHART — a continuum reading or a comparison with data, tagged [approx] in the text (the interpolation, the RAR and BTFR, the SPARC scatter, the predictions, the cluster illustration, the figures).T

V3p32046What the run does not decide: the $\Om$-hard running (Z1) enters no check; the cluster illustration of dark.cluster_coherent evaluates the law $N_{\mathrm{eff}}=(\sum\sqrt{g_i})^2/\sum g_i$ on stated cases, not $N_{\mathrm{eff}}$ from a core population (O1); the identification $\delta\alpha=\arctan(\sigma_v/v)$ (O2) is bounded, not tested, by the SPARC residuals; the named test of B8 (dark.rar_shape) prefers the exponential form by $\chi^2$ but the two forms differ by at most $0.02$ dex per bin against a bin scatter of $0.12$ dex, so the binned relation does not exclude the rational form; the transport run generating the registration rate (C4) is not in the suite.T

O. Open: the conjectures stated ahead of derivation (formerly Y1–Y2)
O1p32048The cluster-core residual as the coherent amplitude addition (12) over the core’s separately virialised composites, $\sqrt{N_{\mathrm{eff}}}$ over the smooth boost, the one law that also gives the Bullet selection. Exposure: the coherence criterion (which concentrations are composites) is not derived; the radial acceleration relation forces $N_{\mathrm{eff}}=1$ within a galaxy (a gas–disk–bulge amplitude sum would boost it by $0.14$ dex, dark.rar_scatter); $N_{\mathrm{eff}}$ is uncomputed ($\simeq1$ for a single dominant galaxy, $4$ for four comparable, $20$ for twenty), and the residual’s samples are relaxed clusters, so $N_{\mathrm{eff}}\simeq4$ is required in relaxed cores. Deciding computation: $N_{\mathrm{eff}}$ from the core galaxy populations of [Sanders 2003; Pointecouteau & Silk 2005].O
O2p32049The collective phase spread as the disk’s dynamical temperature, $\delta\alpha=\arctan(\sigma_v/v_{\mathrm{circ}})$. Exposure: at $\sigma_v/v\simeq0.1$$0.2$ the law gives two to four times the SPARC intrinsic scatter at every $x$; the knee bounds $\delta\alpha\lesssim3.5^{\circ}$; the within-galaxy scatter of $116$ disks shows no correlation with $1/V_{\mathrm{flat}}$ ($\rho=-0.02$). Test: the scatter against measured dispersions.O

Collecting the tags separates the categories directly. Imported are the cardinality $\Om$ and the Hubble datum (A1A2), the synchronisation, amplitude, Fourier-chart, and horizon results established in the programme (A3A6), and the measured relations used only for comparison (A7); these are the sole inputs. Realised are the eight forced identifications (B1B8), each a single realisation carrying its falsifier, and each the place where the physical reading is tested rather than chosen. Derived is the whole of block C, Newton’s law, the floor, the geometric mean, the registration theorem and the radial acceleration relation, the scatter, the external-field effect, and $\Lambda\sim1/\Om$, with no further assumption beyond the realisation each row names (C4: B4; C6: B8); the explanation register X1X11 is what the construction supplies where the phenomenology measures, the predictions P1P6 are the exposures with their falsifiers, and V1V3 the machine verification. The one $\Om$-hard residue is the cross-scale running (Z1), decided by the totality and shared with the number-theoretic instances of the horizon clause. The cluster-core factor, once read as missing mass, is referred to the within-horizon coherent amplitude law (12), a conjecture (O1) pending the coherence criterion and the coherence matrix from observables, not an import and not an obstruction; the identification of the phase spread with the dynamical temperature is the second (O2).

Ledger history

Ledger history. 2026-06-27: the predicate ledger A–C with the block D "Predictions and residues" (D1, D3, D4, D6–D8) and the conjectures Y1–Y2; the revision rounds of July–September 2026 (T17, T25) named the barrier identification B8, the first-passage row C7, the SPARC residual test (rar_scatter.py) and the Fokker–Planck exhibit (deep_regime_fp.py), and owed the named test of B8 (rar_shape.py) to the tree. 2026-09-14 (T26): the explanation list of Section "What the construction explains" becomes block X (X1X11), the predictions become block P (P1P6: D1, D4, D7, D8, D3 renumbered to the body’s P-labels, P5 the coherence-state cluster gas from the body list), the Omega-hard residue D6 becomes Z1, the conjectures Y1–Y2 become O1O2 (block O holds the open rows, as in the corpus), V added, rar_shape.py delivered, every machine-verified row citing the family identifiers of the validation package (finite-ring-space/src/32-dark), accession keys assigned.
