Gravity Analysis Regge Ttcontinuum Certificate Spike
A machine-checked proof that a discrete gravity sum collapses to a simple continuum formula, with no free parameters.
The continuum certificate
In numerical relativity, the Regge calculus approximates curved spacetime by a lattice of flat simplices, and the Einstein equations become algebraic conditions on the edge lengths. The module under discussion takes one piece of that discrete machinery, a sum over six tetrahedral blocks, and proves a clean continuum limit: on the transverse-traceless constraints, the whole 216-term sum equals -(1/4) times the squared norm of the position vector times the squared Frobenius norm of the metric perturbation. The proof is carried out in a machine-checked library of formal theorems, so the algebraic identity is verified by the kernel rather than by hand.
The statement is precise. Let E be a symmetric, traceless 3x3 matrix representing a metric perturbation, and let x be a vector satisfying the transversality condition E·x = 0. The theorem tt_continuum_certificate then asserts that the sum of six block functions, each a literal transcription of 36 terms from the Regge action, equals -(1/4)|x|²||E||²_F. The proof proceeds by expanding each block with a ring tactic, which re-verifies the cancellation of the auxiliary parameters s2, s3, and p, and then discharges the resulting polynomial identity with an explicit cofactor certificate via linear_combination.
What makes this nontrivial is that the auxiliary parameters s2, s3, and p, which stand for sqrt 2, sqrt 3, and pi, are completely free in the block definitions. The theorem shows that despite their presence, the sum collapses to a form independent of them. This is a structural fact about the Regge action: the discrete sum knows about the continuum limit without being told. The result is a certificate in the sense that it provides a formal guarantee that the discrete-to-continuum passage is algebraically exact on the transverse-traceless subspace.
In Recognition Science, this certificate provides a bridge between the discrete ledger of recognition events and the smooth geometry of general relativity. The framework models gravity as a discrete record of events, and this theorem shows that the discrete Regge sum reproduces the continuum wave operator in the appropriate limit. The practical consequence is that the discrete theory is not an approximation to be patched, but an exact rewriting of the continuum physics on a lattice.
The theorem does not claim that the Regge action is the unique discrete action, nor does it address the dynamics of the lattice. It establishes one algebraic identity, fully verified, and leaves the physical interpretation of the discrete ledger as a separate question. What the reader can take away is a concrete example of how a discrete gravity sum, with all its apparent complexity, reduces to a simple continuum formula under the standard constraints.

What this page does not claim
The Regge action is the unique discrete action for gravity. The theorem establishes the dynamics of the lattice or the physical meaning of the discrete ledger. The identity holds for arbitrary metric perturbations without the transverse-traceless constraints.
Verify this page
Every tagged claim above names its theorem. To check one yourself rather than trust this page, elaborate the source module with Lean 4 and audit its axiom basis:

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
Derived articles
This page is generated by a question-recursion engine: the questions its answers raise become the next pages. The current agenda, with open targets marked red:
- How does the discrete ledger of recognition events relate to the smooth metric of general relativity?
- Does the transverse-traceless subspace cover all physically relevant perturbations in the Regge calculus?
- What is the physical interpretation of the auxiliary parameters s2, s3, and p in the discrete action?
- Can the same certificate technique be applied to higher-dimensional Regge lattices?
- Does the continuum limit hold for non-transverse perturbations, or does the identity fail there?
