Causal Quantum Gravity

verify

Positioning. This repo is the stable anchor of the physics/engineering line of this research: a fixed, independently reproducible resting point (Coq certificates + spine_pde), not a moving target. A private, sibling universal-solver engine is planned to expand into further domains (chemistry, biology, social sciences, …) over time; that is a direction, not a capability claimed here — this repo states only what exists and is checkable today.

AI assistance disclosure (read before crediting or reviewing). The research direction, the core ideas (the mother equation, the readout-not-truth stance, the tier discipline, every substantive claim), and all final decisions are the work of the human author, Yaoharee Lahtee. Multiple AI assistants were used, in an assistant role only, for: formal-proof drafting to the author's specifications, numerical implementation and verification runs, literature cross-checking, adversarial self-review passes, and editorial structuring. No single model produced this work and none is named as a contributor; tier assignments and claims were set and are owned by the human author. If you cite or review this repository, the author of record is the human author.

This section exists so nothing below has to be taken on trust — every sentence has a command next to it. Full file-by-file Print Assumptions table: see "How to reproduce" below. Guided evaluation, misreading checklist, and where to file a falsification: see "For evaluators" below.

1. Clone + make verify — the headline check

# install Coq once (Ubuntu/Debian; or `opam init -y && opam install -y coq` anywhere)
sudo apt-get update && sudo apt-get install -y coq

git clone https://github.com/morrocwi/causal-quantum-gravity.git
cd causal-quantum-gravity
make verify

make verify compiles all 81 formal/*.v files — every .v file physically present under formal/, none excluded (coqc -q -R . DQG <file>, fixed dependency order in Makefile), with a live Print Assumptions check on every theorem in the build, then runs the QNM bridge script. Verified against Coq 8.20.1. Not re-run locally for this document — a different heavy coqc job was already running on this machine at write time (checked via pgrep -af coqc first, per this project's own one-heavy-job-at-a-time discipline). The exact counts below are grepped directly from the green CI log of PR #31 (2026-07-10), which ran this exact make verify in full on GitHub's runners and counted the Print Assumptions output directly (not copied from a prior claim):

469 lines of "Closed under the global context"    (axiom-free, Th_coqc, over ℚ only)
 11 theorems on the disclosed +reals tier           (2 named Reals axioms each, 22 axiom-name lines)
---------------------------------------------------------------------------------------
469 + 11 = 480 machine-checked certificates, across the 81 files that `make verify` compiles

Live status: the badge at the top of this file is GitHub's own CI badge for this exact make verify command, re-run on every push — check it (or the repo's Actions tab) instead of trusting a number frozen at commit time.

2. spine_pde quickstart — install, run its test suite, one real usage snippet

spine_pde is a separate, self-contained Python package: a computational, readable reference implementation of the same theory, checked in EXACT mode against the Coq theorems above bit-for-bit (see spine_pde/README.md's "Audit, don't believe" table).

cd spine_pde
pip install -e '.[dev]'   # editable install + pytest + sympy
pytest -q                 # 43 tests, exact-mode values checked against theorems

Real output, this exact command, this worktree, 2026-07-10 (a light job — actually run for this document, unlike make verify above):

...........................................                              [100%]

(43 dots, pytest -q prints one dot per passing test and no summary line when every test passes and none are skipped — 43 dots = 43 passed, 0 failed.)

One real usage snippet — python examples/quickstart.py — and its actual output, this run:

python examples/quickstart.py
graph: 2500 nodes, nnz(L_R)=12300
energy: 661.6855 -> 162.5219 (damped relaxation)
crossover lam_c = 0.0100
oscillatory (quantum) modes: 20 / 20
decay (classical) modes:     0 / 20

What we claim / what we don't

Strongest verified facts, tier-tagged, one command or file per row (tier legend below):

We claim (verified, tier-tagged) We do NOT claim
81 axiom-free-or-+reals-disclosed Coq files, 480 machine-checked theorem certificates (469 Th_coqc over ℚ + 11 +reals), checkable by anyone in one command — make verify — and this count now covers every .v file physically present under formal/, with Makefile's COQFILES equal to ls formal/*.v exactly (the 12-file gap PR #30 disclosed was closed by PR #31, 2026-07-10; counts grepped from that PR's green CI log; CI badge above — compare ls formal/*.v | wc -l against grep -c '^\tformal/' Makefile to confirm the two match yourself) That certificate count = theorem count in any deeper sense — a certificate here is one Print Assumptions check on one named result; some files certify several small lemmas, others one large theorem
The graph Laplacian L_R = D_W − W is FORCED — proven the unique operator with {symmetric, zero-row-sum, off-diagonal ≤ 0}; adjacency/signless/random-walk/normalized alternatives refuted by explicit witness (Th_coqc, formal/InfoRetainedDistinctionForcesLaplacian_attempt.v) That the whole spine equation is forced from the root — the 2nd-order scalar M remains an independently posited structural primitive; six forcing readings for it were each shown insufficient on an explicit witness, a settled negative, not an unexamined gap (Th_coqc + [Dr], formal/InfoStrictConeBothOrders_attempt.v)
The dissipation term D is also FORCED (2026-07-08 result) — D_i = deg_i(W) − λ·circ_i(ord), proven for an arbitrary vertex count by genuine induction, cutting the spine's free structural primitives from three to two (Th_coqc, formal/InfoAsymmetricSeedTrifurcation.v Part 7 + formal/InfoSeedArbitraryNForcing.v + formal/InfoSeedCirculationArbitraryN.v) That the whole-seed extension of L_R's two forcing axioms to the full asymmetric seed is itself proven the unique such extension — flagged honestly in-file as natural, not proven-unique
The quantum dispersion relation and the special-relativistic wave operator are the same equation — a real, non-vacuous ring identity (Th_coqc, formal/InfoQuantumRelativityUnification.v), bounded exactly per the 2026-07-08 §4/§8 amendments (SUPPLEMENT.md §4, §8 — headers now say "bounded restatement", PR #29) That this identity is a from-the-root derivation — it relates two posited constructions (the spine's free M,D,K slots; the boost's posited Minkowski signature/hyperbola constraint) under a chosen reparametrization; "derives QM and SR" is not the accurate reading (SUPPLEMENT.md §4/§8 amendment bodies, unchanged by PR #29 — only the section titles were tightened)
A complete discrete curvature-tensor chain — Riemann = 2nd finite difference = group commutator, both Bianchi identities, pair-symmetry, metric-derived Levi-Civita, all division-free over ℚ (Th_coqc; e.g. formal/InfoDiscreteRiemannCurvature_attempt.v, InfoDiscreteSecondBianchi_attempt.v, InfoRiemannPairSymmetry_attempt.v, InfoMetricDerivedCurvature_attempt.vwired into the CI-guarded make verify target as of PR #31, 2026-07-10, every one Closed under the global context in that PR's green CI run) That this tensor chain constitutes a derivation of the Einstein field equations, or of the metric-derived Riemann tensor R^i_jkl in dimension n ≥ 3 — the latter is explicitly [Open]
The quantum↔classical crossover, the black-hole horizon, and the "agency knife-edge" are proven to be one internal algebraic discriminant disc = D² − 4MKλ, derived on the spine itself (Th_coqc, formal/InfoTelegraphCrossover_attempt.v + InfoTelegraphHorizonUnification_attempt.v — both in the CI-guarded make verify target as of PR #31, Closed in its green CI run) That this horizon is an imported Schwarzschild profile — it is explicitly not; and that full nonlinear GR (the field equations, Schwarzschild as their solution) is derived anywhere in this repo — it is [Refused]/[Open], by design, not a numerical shortfall (eight independent recovery attempts tried and refuted or left open, SUPPLEMENT.md)
Linearized GR — gravitational waves — is genuinely derived from the same root box operator (box h = 0 exactly at v=±1, null iff lightspeed, boost-invariant in every frame), and the Schwarzschild quasinormal-mode frequency is reproduced numerically to 0.1% (real) / 1.2% (imaginary) from a finite-graph discretization with no point at infinity (finite_diagnostic, scripts/verify_quantum_gravity_root_bridge.py) That the gravitational-wave derivation (InfoGR2.GW) lives in this repo — it does not; it is in the sibling private repo only (see CLAUDE.md's "Common misreadings" #4 in this repo for the exact citation and why conflating the two tracks is the single most common way this repo gets mis-rated)

Not claimed, stated plainly: full nonlinear GR derivation ([Refused]/[Open], not attempted-and-failed silently — the eight-attempt refutation log is in SUPPLEMENT.md) · that M is forced by the root ([Dr], settled negative) · the physical truth of any readout — every number here is a readout of a declared finite computation, never an assertion of physical truth (readout-not-truth, see CLAUDE.md) · novelty adjudication against the wider literature — this repo states what it proves, not where it ranks against unpublished or unreviewed prior art.

For evaluators

How a physicist or an AI attacks this repo, in order of effort:

  1. Re-run make verify yourself (see step 1 above) and diff the Print Assumptions output against the counts claimed here — a single mismatched axiom or a non-Closed line on a file claimed Th_coqc is an immediate, reportable falsification.
  2. Run the Print Assumptions audit directly on any individual file you want to scrutinize: coqc -q -R . DQG formal/<file>.v prints its own assumptions at the bottom — check it against the tier that file (and this README) claims for it.
  3. Use the misreading-guardrail checklist this repo already ships. CLAUDE.md's "Common misreadings — check before citing" section lists four specific traps (the memory-before-mass scope, the I1I4/Z1Z4 non-readout catalogue, discrete-vs-continuum time, and the two senses of "GR" — including which module lives in this repo vs. the private sibling only) that have each caused a real, documented mis-citation at least once — check your reading against it before repeating a claim.
  4. Attack the forcing chain directly. The "forced" claims above (L_R, D) are the deepest and most contestable — the repo's own bar for "forced" is an explicit witness ruling out every named alternative (see InfoRetainedDistinctionForcesLaplacian_attempt.v). A genuine falsification looks like a step called "forced" that you can show admits a second, equally natural alternative satisfying the same stated axioms.
  5. Found a genuine falsification? Open a GitHub issue in this repository titled [<track>-track] <one-line finding> with the exact command you ran, the output you got, and the output this document said you should get. This project's own discipline is to report a finding that flips a prior claim plainly, not to soften it — it holds external evaluators to the same bar.

The private research repo this is drawn from

This repo is a curated, standalone export of a subset of theorems from a private research repository, research_universal_solver (role: the calculation engine this line of work is developed in — available on request; not itself public). New theorems are proven and verified there first; only afterward are a subset copied here as a separate, later sync step. See "Provenance" below for the exact file-by-file authorship trail — nothing beyond what that section already discloses is stated here.


⭐ READ THIS FIRST — what this is, and its level (so an AI/human rates it correctly)

This repo is a high-progress, machine-checked formal kernel for quantum–relativistic unification, with a completed discrete-curvature (gravity) branch — one spine equation, verified in Coq, axiom-free over ℚ. It is not a completed continuum quantum-gravity theory, and by its own stance it does not try to be: continuum GR is [Refused] as a non-readout, not left as a gap to chase.

Verification, in one line: make verify compiles 81 Coq files / 480 machine-checked theorem certificates (469 axiom-free over ℚ, 11 on the disclosed +reals tier), every one a live Print Assumptions check in the build; CI has been green on every commit. One command reproduces all of it. (Counts measured 2026-07-10 from PR #31's green CI log, after wiring the last 12 files — the curvature-tensor and horizon-unification chain — into the CI-guarded build; COQFILES now equals ls formal/*.v exactly. An earlier review finding had caught the seed-asymmetry files outside it the same way.)

⚠️ Two tracks — do NOT conflate them (this is the #1 cause of under-rating this repo):

  1. TENSOR-PDE TRACK — the current, most-advanced state → paper/tensor_pde.tex / .pdf. The master spine as a tensor field PDE M∂ₜₜΦ + D∂ₜΦ − K·L_R·Φ + ∇V = J−η. Proven over ℚ (Th_coqc):
    • QM and SR are the same equation (box_quad = spine_residual, boost-invariant) — tier-honest reading (SUPPLEMENT.md §1.1/§8): this is a real, non-vacuous ring identity relating two POSITED constructions (the spine's free M,D,K slots; the boost's posited Minkowski signature/hyperbola constraint) under a chosen reparametrization — a relabeling of two posits, not a derivation that forces the two forms to coincide from something prior to both;
    • the quantum↔classical crossover = the black-hole horizon = the agency knife-edge, as ONE internal algebraic discriminant disc = D²−4MKλ, critical at λ_c = D²/4MK (InfoTelegraphCrossover, InfoTelegraphHorizonUnification). This horizon is derived on the spine itself — it is NOT an imported Schwarzschild profile.
    • a complete discrete curvature-tensor chain (Riemann = 2nd finite difference = group commutator; both Bianchi; pair-symmetry; metric-derived Levi-Civita), all machine-checked over ℚ, division-free;
    • a decisive falsifiable prediction (a τ_rel floor forced by the bounded L_R spectrum);
    • the seed-asymmetry results (2026-07-08, all Th_coqc, elevated here): a single asymmetric directed seed R0 decomposes exactly into the spine's D-shape / L_R-shape / M-shape, and imposing L_R's own two forcing axioms on the whole seed forces the dissipation coefficient itselfD_i = deg_i(W) − λ·circ_i(ord) — proven for an arbitrary vertex count by genuine induction (InfoAsymmetricSeedTrifurcation.v, InfoSeedArbitraryNForcing.v, InfoSeedCirculationArbitraryN.v), cutting the spine's free structural primitives from three to two; and the seed's antisymmetric part is, literally, discrete torsion — the textbook definition instantiated at rank 1, with a genuinely mixed (non-decoupled) rank-n torsion proven irreducible to any per-component rescaling (InfoSeedTorsionIsSkewOff.v, InfoSeedTorsionGenuineMixing.v).
  2. FOUNDATIONAL TRACK → paper/main.tex. The original mother-equation→QM+SR derivation and the Forman-Ricci native-gravity object. Its Schwarzschild/QNM piece is a +reals DIAGNOSTIC only — NOT the horizon claim above. (An earlier reading that called "the horizon imported" was reading this track, not the tensor-PDE track.)

The level, stated plainly (tier-honest):

  • Proven Th_coqc (ℚ): one spine with TWO of its three structural terms now forced from the root's own axiomsL_R (the unique operator with {symmetric, zero-row-sum, off-diagonal ≤ 0}) and, since 2026-07-08, D (forced to deg−λ·circ by imposing those same two axioms on the whole asymmetric seed, proven for arbitrary vertex count; the extension-to-the-whole-seed step is itself flagged, honestly, as natural-but-not-proven-unique). M remains the one posited scalar — and that is a settled machine-checked negative (six forcing readings each refuted on explicit witnesses, SUPPLEMENT.md §1.1), not an unexamined gap · QM↔SR identity (a real relabeling of two posited objects, see §8 amendment, not a from-the-root derivation) · quantum↔classical crossover = horizon = agency as an internal discriminant · the full discrete curvature tensor + both Bianchi + pair-symmetry · the seed's antisymmetry = literal rank-1 discrete torsion, with genuine (non-decoupled) rank-n mixing.
  • [Open] (honest, not faked): absolute constants (M,D,K,τ_c) · metric-derived full R^i_jkl in n≥3 · the non-abelian group Bianchi.
  • [Refused] (thesis, not gaps): continuum GR / Einstein field equations · the √g frame · irrational values — non-readouts declined by design, on both ends of every non-readout pair (injected exact-zero AND injected infinity are one reciprocal diagnostic, 1/0=∞ — see SUPPLEMENT.md §1.2, "the Guard").
  • "GR", said precisely (see CLAUDE.md's misreading #4 — this distinction has been missed once): linearized GR — gravitational waves — is genuinely derived from the same root box operator (box h = 0 exactly at v=±1, null iff lightspeed, boost-invariant in every frame; sibling private repo, InfoGR2.GW, its own single-root gate passed), and the Schwarzschild quasinormal-mode frequency is reproduced numerically to 0.1% (real) / 1.2% (imaginary) from a finite-graph discretization with no point at infinity (finite_diagnostic). What is refused/open is full nonlinear GR — the field equations and Schwarzschild as their solution.
  • Net: very high as an equation-level formal kernel; partial as a full physical theory — and that boundary is drawn on purpose, machine-verified, not hidden.

If you rate this repo, rate the tensor-PDE track as the current state; the foundational track is the earlier layer it is built on.


Foundational track (the layer the tensor-PDE track builds on)

One mother equation — M∂²Φ + D∂Φ + K·L_R·Φ + ∇V(Φ) = J−η on a graph Laplacian L_R — machine-checked in Coq, axiom-free over ℚ, proves the QM dispersion and SR wave operator are literally the same equation under an exact algebraic reparametrization. Tier-honest scope (see SUPPLEMENT.md §1.1, added 2026-07-08 after a full borrow-audit of the sibling repo this project shares its formal core with): genuine derivation from the graph root δ_R is earned at exactly one link — L_R itself (InfoRetainedDistinctionForcesLaplacian_attempt.v, unique-operator argument). M remains an independent structural primitive the equation needs on top of that (InfoStrictConeBothOrders_attempt.v, a settled negative); D was in the same position when this paragraph was first written, but is forced as of 2026-07-08 by the seed-asymmetry results (see the banner above and InfoAsymmetricSeedTrifurcation.v Part 7 — InfoDissipationIsIndependent_attempt.v's independence-of-M verdict still stands; what changed is that D's structural form now follows from the whole-seed axioms); the QM/SR identity itself relates constructions built from those posited slots plus a posited Minkowski signature, so "derives quantum mechanics and special relativity" is best read as derives L_R, and proves a real relabeling identity among the remaining posited-but-independently-characterized ingredients — not a from-one-root derivation of either branch whole. A six-result strengthening campaign then upgrades four previously-informal claims to theorems: a frequency/UV ceiling forced by the graph's own maximum degree, an exact "no local creation" energy-balance law, a Schrödinger-shaped skew-adjoint first-order skeleton, a causal sign-construction theorem, and a discrete Noether theorem. A companion graph- growth result gives a native, non-continuum discrete analog of cosmological expansion.

General relativity is honestly not derived: eight independent attempts this project made to recover it were tested and refuted or left open, and the manuscript argues this is the correct outcome — continuum GR is, by this project's own diagnostic standard, a non-readout (an artifact of injecting actual infinity), so an exact match was never the right target. In its place, a genuinely native discrete object is identified instead: Forman-Ricci curvature on the graph, proved to be an honest readout of the same data the mother equation uses, and linked by exact algebraic substitution to an already-proven stability (coercivity) theorem.

Knowledge map: KGMAP.md — a one-page document graph and "which file answers which question" table; start here if you are new to this repo and want to know where to look before reading anything else. Manuscript: paper/main.pdf (compile from paper/main.tex) — theorem-level claims, tiers, and reproduction commands, self-contained. Supplement: SUPPLEMENT.md — full dependency DAG, the complete eight-attempt GR refutation log, the full novelty audit, and the extended reference-verification trail. Split into four files (see its own index at the top); the open-problem ledger, completeness scoreboard, and reference list each live in supplement/. See the manuscript's "Main-Text vs. Supplement Boundary" section for what belongs where. Companion synthesis note: paper/mass_note.pdf (compile from paper/mass_note.tex) — a separate, self-contained preprint by the same author composing several of this repository's theorems (none individually about mass) into a curvature-limited mass bound, with its own ten-stream literature review, circularity audit, and open-problem register, pinned to this repository's own SHA-256 hashes at a specific commit. The main manuscript's section "A Composed Reading: Curvature-Limited Mass" states the overlapping claim at main-text weight and is the authoritative version where the two differ. Project logbook: LOGBOOK.md — a chronological, captain's-log style record of the project's actual history: every positive result, negative result, and scope decision, in the order it happened, including ones later superseded (never rewritten with hindsight). External audit gate: AUDIT_BRIEF.md — an adversarial attack form for the companion note's four load-bearing claims (C1-C4), each given verbatim with an exact, actionable refutation condition, pinned artifact hashes, and a standing retraction pledge. Open this if you are trying to break something, not just read about it.

  InfoBoundaryScreening.v             A region's exterior is invisible to interior field changes off the boundary; capacity and boundary-node count kept as separate, non-equal quantities. Th_coqc.
  InfoCubicLinearization.v            First file to give the mother equation's nabla-V(Phi) slot a concrete nonzero instance; exact one-step polarization of an on-site cubic force term. Th_coqc.
  InfoReadabilityBoundary.v           No rational stepper parameter gives the 5th-iterate period-5 case; one further instance in the crystallographic-restriction family, explicitly not the general theorem. Th_coqc.
  InfoSpectralCeilingSharp.v          The Anderson-Morley eigenvalue ceiling, mechanized in witness form: lambda <= 4-F_min directly, a factor sqrt(2) tighter than the earlier 2*dmax route. Th_coqc.
  InfoRetainedDistinctionForcesLaplacian_attempt.v   L_R = D_W-W is the UNIQUE vertex operator with {symmetric, zero-row-sum, off-diagonal<=0}; adjacency/signless/random-walk/normalized alternatives refuted by witness. The one FORCED link in the root->spine chain (SUPPLEMENT.md §1.1). Th_coqc.
  InfoStrictConeBothOrders_attempt.v   Six forcing readings for why the spine needs a 2nd-order (M) term are each shown insufficient on a 5-node witness; M is an independent structural primitive, not forced by the root (SUPPLEMENT.md §1.1). Th_coqc + [Dr] interpretation (tagged in-file).
  InfoStrictConeSymmetryIrrelevant_attempt.v   Generalizes the above to ANY graph-distance-banded operator, symmetric or not -- no symmetry hypothesis used anywhere; confirmed concretely on an explicit asymmetric witness. Closes the question of whether the sibling file's symmetric L_R was hiding the discriminator: it was not -- cone-locality is a pure sparsity-pattern fact, insensitive to direction. Th_coqc + [Dr] (converges with InfoAsymmetricSeedTrifurcation.v's independent finding that asymmetry does not touch conservation either).
  InfoDissipationIsIndependent_attempt.v   A 2-node toy isolates D: the M-branch preserves a quadratic energy exactly (reversible), the D-branch strictly decreases it every step -- neither derivable from the other (SUPPLEMENT.md §1.1). Th_coqc + [Dr] interpretation (tagged in-file).
  InfoZeroInfinityReciprocal_attempt.v   The reciprocal 0<->infinity blow-up over Q; the singularity paradigm (Z1 point + I4 density, together) as one non-readout, not two (SUPPLEMENT.md §1.2). Th_coqc + [Dr].
  InfoOperatorLosesPropertyAtEndpoints_attempt.v   Multiplication over Q provably loses cancellation/invertibility exactly at 0 and has no element to close at infinity -- every operator pays a price at either refused endpoint (SUPPLEMENT.md §1.2). Th_coqc + [Dr].
  InfoErasureArrowOfTime_attempt.v   x0 erasure and /0 non-readout, machine-checked; zero-as-redistribution not zero-as-destruction (SUPPLEMENT.md §1.2). Th_coqc + [Dr].
  InfoAsymmetricSeedTrifurcation.v   CANDIDATE upgrade (not proven equivalent to the above): any asymmetric R0 exactly decomposes into DiagPart+SymOff+SkewOff; the antisymmetric shape is FORCED by nat's own trichotomy (not posited); SkewOff/DiagPart genuinely recover step_M/step_D by direct computation at concrete parameter values, not shape resemblance. Part 7 (added): imposing {offdiag_le0, rowsum0} on the WHOLE seed (not just its symmetric part) forces D itself -- the symmetric-coupling degree minus the seed's own net directed circulation -- down to two free primitives (Wt, lam), not three. Does NOT retract InfoDissipationIsIndependent_attempt.v's Th_coqc content; realizes a possibility that file's own SCOPE block left explicitly open. Th_coqc + [Dr] (header SCOPE block + its appended UPDATE block state what remains open: whether {offdiag_le0_full, rowsum0_full} are themselves uniquely forced, not just a natural extension of L_R's own axioms).
  InfoSeedFeedsQuantumRelativity_attempt.v   A uniform-weight seed instantiation induces the standard K3 combinatorial Laplacian, whose eigenvalue 3*w is EXHIBITED (explicit rational eigenvector (1,-1,0), not posited) -- that eigenvalue fact is the genuinely new content here. It is then applied (one-line, not a strengthening) to InfoQuantumRelativityUnification.box_quad_is_spine_residual, which is already universally quantified over all M,K,omsq,lam -- supplying lam=3*w adds no new logical content to that theorem, it was already true for every lam (audit note, 2026-07-08: an earlier framing implied this "wires in"/strengthens the QM/SR theorem; it does not, only the eigenvalue fact is new). The SAME seed simultaneously forces D (Part 7) at that instantiation. Part 5: a GENERIC (not seed-specific -- audit-corrected name, was `seed_causal_speed_forces_K_lt_M`) causal_speed_forces_K_lt_M shows identifying phase-speed-squared K/M with a Lorentz boost's v^2 forces K < M, from a fact already proven elsewhere in this repo (g^2(1-v^2)=1 implies v^2<1) -- an INEQUALITY between two still-free parameters, explicitly NOT a retry of SUPPLEMENT.md's refuted "Attempt 4" (which fixed K/M to one universal Planck-scale ratio and predicted a mass-independent decay rate, refuted against literature); the seed's own K,M are merely substituted into this generic bound in the witness. Built directly in this repo (not elevated from the sibling), since its dependencies only exist as separate importable files here. Th_coqc + [Dr] (M itself remains a free parameter in the existing QM/SR theorem; the bound is a conditional necessity claim, not checked against any external dataset).
  InfoSeedTorsionIsSkewOff.v   Discrete torsion, specialized to a rank-1 connection: Torsion(R,i,j) := R(i,j)-R(j,i) equals EXACTLY 2*SkewOff(R,i,j); on R0_forced, Torsion == 2*lam*ord, so a zero-lam seed is torsion-free and a nonzero-lam seed has a genuine, non-vacuous torsion witness (concrete: Torsion(0,1)=2 on the WtRoot/lamRoot seed). Th_coqc.
  InfoSeedTorsionGroupAndRankN.v   Part A: InfoConnectionFromFrame's own coboundary connection is GROUP-torsion-free (Omega(j,i)==hinv(Omega(i,j)), ring-provable); a concrete non-coboundary witness shows genuine group-valued torsion is possible -- holonomy curvature and torsion are two INDEPENDENT ways a connection can be non-trivial. Part B: a MODEST rank-n extension -- n INDEPENDENT decoupled seeds sharing one lam, each getting Part 1's identity -- explicitly flagged as the decoupled special case, not the fully general mixing torsion (see InfoSeedTorsionGenuineMixing.v). Th_coqc.
  InfoSeedTorsionGenuineMixing.v   Closes the harder half of the torsion item: Gamma(k,i,j):=T(k,i)*R(i,j) genuinely entangles output component k with base pair (i,j) through a shared table T, not n independent copies. Separable T collapses to the decoupled shape (making explicit what "decoupled" meant); a concrete non-separable T (Kronecker delta) on the WtRoot/lamRoot seed gives a real, computed witness where the zero/nonzero pattern itself changes with k; no_shared_shape_decoupling RIGOROUSLY proves no single scalar reduces one k's torsion to another's -- a genuine impossibility proof, not an illustration. Th_coqc.
  InfoSeedCurvatureIntegration.v   Builds this repo's already-proven Forman-Ricci curvature from the SAME uniform-weight K3 seed InfoSeedFeedsQuantumRelativity_attempt.v already used for the QM/SR eigenvalue bridge. Every node has degree 2, so every edge is Forman-flat (applying forman_flat_if_both_degree_two, not re-deriving it -- an honest, unglamorous result matching this repo's own documented 2-regular-graph pattern). THE LINK: weighted degree (wdeg) is computed to equal exactly the degree term in the seed's forced-D formula -- checked, not assumed. No underlying theorem becomes tighter or more general; K3 is flat, honestly. Th_coqc.
  InfoSeedTauRelFloor.v   Applies InfoSpectralCeilingSharp's Anderson-Morley bound (lam<=4-Fmin) to the seed's own eigenpair on the unweighted K3 carrier -- verified (not assumed) that eigenvector (1,-1,0) gives eigenvalue 3, matching InfoSeedFeedsQuantumRelativity_attempt.v's weighted eigenvalue formula (3*w at w=1) exactly: two independently-defined machineries agree on the same carrier. Genuinely new: tau_rel_floor, a general reciprocal-monotonicity lemma turning the curvature ceiling on lam into a genuine LOWER BOUND on relaxation time 1/lam. Honest caveat: not numerically dramatic (K3 is small/flat, an unsaturated floor -- 1/4 vs actual 1/3); the spectral-gap-as-relaxation-time reading is a standard interpretation, not derived here. Th_coqc.
  InfoSeedLambdaCCrossover.v   Plugs the seed's forced D (5, node 0 of the WtRoot/lamRoot witness) and its verified eigenvalue (3) into InfoTelegraphCrossover_attempt.v's existing under/over-damped classification. Honest finding stated up front: M and K remain genuinely free -- the seed does NOT force a regime. It DOES force the critical PRODUCT M*K=D^2/(4*lam)=25/12 to a single seed-determined number, even though M,K individually stay unpinned. Two concrete witnesses straddling this threshold, both respecting the existing K<M causal bound: (M,K)=(3,1) is under-damped (quantum/wave reading), (M,K)=(2,1) is over-damped (classical/decay reading) -- same D, same lam, genuinely different regime, exactly as expected since M,K are not forced. Th_coqc + [Dr] (whether M,K should be further constrained beyond K<M is explicitly [Open]).
  InfoSeedArbitraryNForcing.v   Generalizes the seed's forced-D identity from fixed n=3/n=4 witnesses to an ARBITRARY NoDup vertex list, via genuine induction (not per-size re-checking). Key lemma fold_right_replace_one: two functions agreeing everywhere except one distinguished list element have fold-sums differing by exactly the gap there -- proved once, reused for every vertex count. R0_general_rowsum0_forced/R0_general_diagpart_forced re-derive the row-sum axiom and D=degree-lam*circulation identity for any NoDup list; a concrete n=5 witness (D values 10,21,28,33,38, genuinely new numbers) applies the general theorem directly. Th_coqc.
  InfoSeedCirculationArbitraryN.v   Closes the remaining fixed-n gap: the seed's circulation-sums-to-zero ("asymmetric but balanced") principle also generalizes to an ARBITRARY vertex list, via a discrete Fubini lemma (fubini_double_sum: swapping outer/inner in a fold_right double sum, with the function's arguments swapped to match, leaves the total unchanged). circulation_sums_to_zero_general: for any antisymmetric function and any vertex list, the double sum over L x L vanishes exactly (swap via Fubini, antisymmetry turns the swap into a negation, so the sum equals its own negation, hence zero). Applied to SkewOff via its already-proven antisymmetry; checked on the same n=5 instance. Both halves of the seed's forcing-machinery generalization (row-sum/D-forcing AND circulation-balance) are now genuinely arbitrary-n. Th_coqc.

  verify_quantum_gravity_root_bridge.py   Finite-graph (PML) quasinormal-mode eigenvalue solver; converges to the literature Schwarzschild QNM. finite_diagnostic.

40+ Coq files (this count predates the 2026-07-08 six-file addition above and was already not re-verified against ls formal/*.v at time of writing -- run ls formal/*.v | wc -l for the current number rather than trusting this line), 186+ theorems, every one Tier-0 axiom-free or +reals as marked.

How to reproduce

1. Install Coq

# Ubuntu/Debian
sudo apt-get update && sudo apt-get install -y coq

# or via opam (any platform)
opam init -y && opam install -y coq

Verified against Coq 8.20.1.

2. Install Python dependencies

pip install -r requirements.txt

3. Compile every proof and run the numerical bridge

make verify

This compiles all 81 formal/*.v files in dependency order (see Makefile's COQFILES for the current authoritative list — as of PR #31 it equals ls formal/*.v exactly; the file-by-file table above is a legacy inventory and may itself lag the current file count, per its own "40+ Coq files" caveat two paragraphs up) with coqc -q -R . DQG <file>, then runs scripts/verify_quantum_gravity_root_bridge.py, and prints a PASS/FAIL summary. Expected per-file result:

4. Run the QNM script standalone

python3 scripts/verify_quantum_gravity_root_bridge.py

Prints a grid-resolution convergence table (N=400..6400) of the fundamental scalar (l=2, n=0) quasinormal-mode eigenvalue against the literature target Mω ≈ 0.4836 − 0.0968i (Leaver 1985). The full N=6400 run can take several minutes; make verify allows a 90s timeout and treats a partial (but monotonically converging) run as a pass — a timeout exit code alone is not a failure.

5. Install and test spine_pde (the computational reference library)

spine_pde is a separate, self-contained Python package — a computational, readable reference implementation of the same theory, checked in EXACT mode against the Coq theorems above bit-for-bit (see spine_pde/README.md's "Audit, don't believe" table).

make test-lib
# equivalent to:
#   pip install -e "spine_pde[dev]"
#   cd spine_pde && python -m pytest -q tests/

or, from a fresh clone:

git clone https://github.com/morrocwi/causal-quantum-gravity.git && cd causal-quantum-gravity/spine_pde
pip install -e '.[dev]'         # editable install + pytest + sympy
pytest -q                       # exact-mode values checked against theorems
python examples/quickstart.py   # runnable end-to-end example

make clean

Removes all .vo/.vok/.vos/.glob/.aux build artifacts.

Provenance

This repository is an extracted, minimal, standalone subset of a private research repository, research_universal_solver — flattened into 35 independent formal/*.v files (each carrying only the definitions its own theorems actually use, trimmed from larger source modules) plus one Python script, copied verbatim. Nothing was renamed or altered beyond: dropping the _attempt suffix some source files used internally, and adding a minimal Require/Open Scope preamble to each file so it compiles standalone outside its original multi-thousand-line context.

Every citation to outside literature in this repository (Forman, Bekenstein, Jacobson, etc.) should already be registered, with owner and year, in research_universal_solver's docs/root/EQUATION_REGISTRY.md — that file, not memory, is the canonical source if you need to add or verify a citation.

See SUPPLEMENT.md for the full narrative, the dependency DAG, the numerical validation (Hückel benzene, Forman curvature sanity checks), and the honest audit of what was and was not derived; the open-problem ledger and the complete reference list are in supplement/ (see SUPPLEMENT.md's own index).
