Gravitation as Phase Synchronisation

We derive gravitation on the finite relational substrate that forms the holographic encoding of the observable physical space-time. The derivation consumes three realisations: mass is the cardinality of a phase-locked cluster, distance is decoherence, and time is the observer’s scale-dilation. The substrate is a field and has no proper ideals, so a massive object is never an ideal of it: its frame drifts, and gravity is the relaxation of that forced drift.
Each row carries one status tag. Every derived statement is a residue of the Carrier, never a conjecture: a small residue a bounded observer can access (a theorem), or an $\Omega$-hard residue fixed beyond the horizon. The remaining tags mark imported inputs, realisations and definitions; a prediction is a theorem, stated with its falsifier, that names the realisations it rests on. The blocks follow the paper: A the inputs, B the realisations (Section 3), C the derived rows (Sections 4–7), X what the construction explains and P the falsifiable predictions of the two subsections above, Z the $\Omega$-hard residue. The source column names the body statement and the rows a theorem rests on. A machine-verified row also carries its witness tokens. The token py names the check of the ledger file that decides the row. The tokens lean and leanML name the row’s declaration in the Lean core and on Mathlib. The Reproducibility section describes the ledger file and the two libraries.

A. Inputs: imported, not derived here
A1p21001The finite substrate: the torsor Carrier, coordinatized by a frame as $\F_\Omega$, its cardinality the Carrier identity $\Omega=4S+1$ with the measured $S\sim10^{122}$ (Planck units) locating the coherence horizon, with the phase cycle $C_{\Omega-1}$, the quarter-turn core $Q_4$, the drive (time is scale-dilation, each Subject’s own), the coherence horizon $\sqrt\Omega$, and the resolution floor $1/\sqrt\Omega$.I

A2p21002The three frame freedoms: the frame space is a torsor under $\mathrm{SL}_2(\F_\Omega)$, the spatial chart three-dimensional per frame, its continuum shadow the $3$-sphere.I
A3p21003The quadratic extension $K$, the Frobenius involution, the Lorentzian norm form, and the boost cycle (the Dirac layer).I
A4p21004Composite coherence: a bound cluster is one synchronised drive orbit (offset confinement, the $m$-body synchronisation lemma), coupling with coefficient $m$ against an incoherent $O(\sqrt m)$.I

B. Realisations: mathematics as physics (the constitutive moves)
B1p21010Gravity is the relaxation of forced frame drift: a field has no proper ideals, so every embedded massive shell is non-ideal and its frame drifts; reducing the mutual drift (raising coherence) is identically motion toward smaller separation.R
§ 1, 3
B2p21011Mass is winding rate: the per-cell rate identification, one $Q_4$ datum in the channel $C_{\p-1}\cap C_{2(\p+1)}=Q_4$, tested against its falsifier at the instance [Akhtman & Voether 2026]; $E=mc^2=hf$ an identity; the composite coefficient $m$ is derived (C1), not constitutive.R
Def. 3.1, 3.2

B3p21012Distance is decoherence, counted in the relational steps of the observer’s chart.R

B5p21014The single realisation: the objects we weigh are coherent composites.R

B7p21065The count of the registration set at the operational cut is the coordinate area in Planck cells, $|R_\partial|=4\pi r_f^{2}/\ell_P^{2}$ up to the solid-angle recalibration of the chart. Falsifier: a collapsed object whose externally resolvable capacity is measured at the Bekenstein–Hawking value.R
Prop. 6.8
B8p32014The cosmological constant is the curvature of the wrapped finite chart (32:B7). Falsifier: $w\neq-1$, or a negative or scale-varying $\Lambda$.R
§ 8.1
B9p32015The masking barrier is the coincidence amplitude: registration fails when the killed noise walk first traverses the signal’s amplitude $\sqrt x$, coefficient one (32:B8). Falsifier: an approach to Newton departing from $1-e^{-\sqrt x}$ beyond the binned-RAR uncertainty, or a knee displaced from $cH_0/2\pi$.R

python source
Gold: the python check that decides the predicate, at its line in the script (the source, rendered on this site); on hover the deciding family and the families that corroborate it, and the verdict of the last run (red when it fails). The script page's bar runs the predicate's cell of the package's notebook on Google Colab (one cell per predicate; the whole notebook from the header badge).
Lean, the coreLean, Mathlib
The predicate as one Lean declaration, named by its accession key (p21001) — the conjunction of the theorems that prove it — at its line in the rendered module, one mark per library that proves it, the core's first. Green: the core (lean/FrcCore) — the statement on the shell ring, by computation and induction, no Mathlib, no axioms: the finitist witness. Violet: Mathlib (lean/FrcLedger) — the classical statement for every shell on Mathlib's hierarchy (its axioms, propext, Classical.choice, Quot.sound, on hover). Red: a proof the gate rejects (an unfinished proof, native_decide) — not a witness. A predicate proved in both libraries shows both marks; one mark, one proof. The module page's bar opens the module as one executable file in Lean Live (the core on plain Lean, no Mathlib; the file elaborates in the browser and prints every predicate's axioms at its end); the header's two Lean badges count the marks of each colour and open the two executables.

rests on
The predicates it rests on, by label: realisations, definitions and imports of this ledger, predicates of other ledgers (32:B3) and of the master (00:D15).
Read by block, the surface is small. Imported (A1–A9) are the substrate and its arithmetic, the Lorentzian–Dirac layer, the composite-coherence results of [Akhtman & Voether 2026], the lattice and synchronisation machinery, the continuum stiffness templates, the measured constants used for comparison only, and the minimal-instance results of [Akhtman & Voether 2026]. Realised (B1–B9) are the nine realisations, each stating what a physical term denotes in the substrate: gravity is drift relaxation, mass is winding rate, distance is decoherence, the clock tick and the decoherence count are one capacity, the objects we weigh are coherent composites, a frame change is a gauge symmetry, the count at the operational cut is the coordinate area, dark energy is the curvature of the finite chart, the masking barrier is the coincidence amplitude — constitutive, not interpretive, each defended by the totality of its derived consequences and contested only through them. Everything else is derived (block C): from two definitions, one frame normalisation, one counting lemma, and the single composite realisation, with no field equation, action principle, or metric posited, the potential, the force, the equivalence principle, the redshift, the deflection, the perihelion, the frame dragging, the operational horizon, the area law, the radiative sector, the rotating solution, and the primordial spectrum come out as outputs. The explanation register X1–X8 is what the construction dissolves or derives; the predictions P1–P8 are the exposures this dependency structure offers, the acceleration floor and the registration crossover among them. One residue sits beyond the bounded observer: Z1, the cross-scale running of $a_0$, $\Omega$-hard by the same factorisation of $\Omega-1$ that decides the number-theoretic instances of the horizon clause [Akhtman & Voether 2026], and the same object as the dark-sector residue of [Akhtman et al. 2026]. Tags: I 9, R 9, T 40, $\Omega$-hard 1. Of the theorem rows, every one with a py token is decided by a check of the ledger file; those with a lean token — the Carrier register and the laboratory Carrier (C2, C5, C16), the channel (A9), the count face and the merger law (C13), the cover triangle (C7, C8, C25), the defect’s recurrence and the pair tally (C21, C1), the Gauss law and the character (C11), the Frobenius trace (C6), the post-Newtonian coefficients (C8, P6), the registration root (C19), the central difference (C9), the Laplacian’s symbol (C15) and the shift theorem (C20) — are proved in the core with no axioms; those with a leanML token are proved on Mathlib’s hierarchy, the numerals of C12, C13, C18, P1–P4, P7 and P8 bracketed on the reals at the scale import. The realisations of block B, the synchronisation dynamics (C1’s gradient flow, C22), the rotating solution beyond its symbol (C17) and every confrontation with data are outside the formal layer. What the synchronisation reading adds to gravitation is the provenance of each part: the product $m_1m_2$ from coherent additivity, the $r^{-2}$ from harmonicity in the three frame freedoms, the universal sign from the shared arrow of the dilation, $G$ from the unit capacity of the relational channel, the equality of space and time bias from the unity of that channel, the slip core from its saturation, the operational horizon from its resolution floor; and, at the opposite end of the acceleration scale, the galactic transition from the same floor read as noise. One substrate, one channel, one floor; the constants are its bookkeeping.
