Follow a result back to its evidence.

Choose a result, inspect its assumptions, then run the calculation that supports it. Each check answers a specific question. The original status and the scope of that answer stay attached.

Start with the E₈ construction.

The first module builds the lattice explicitly. It checks the glue, constructs its 240 roots and tests the lattice basis. You can read the source before running it.

Question: Does the explicit construction give the even, unimodular E₈ lattice?
What is tested: Shared ℤ₄ discriminant data; glue norms 5/4 + 3/4 = 2; 240 roots of squared length 2; an integral, even basis with determinant 1.

Read the Python source

Python runs in your browser using Pyodide. The first run downloads the runtime. Its output appears in the existing verification viewer, including any failure and the local reproduction command.

This is a mathematical lattice check. Identifying that lattice with a physical system requires additional arguments and retains its own status.

FTR.CRDISC.01: the preregistered cross-ratio check (self-code review Priority 4 / v566 S9), executed on its DISCRETE half — the four solver corners are the in-repo Sheet-Diamond kernels J,K,C,F = M(1,t), t = −2..1 (v224, dets (2,4,14,32)), and the corpus's one canonical declared solver reading, the Koide anchor response ℓ(M) = aᵀM·1 (v183), reads (26, 35, 44, 53) on them: CR = 4/3 EXACTLY, and the fit-free reconstruction forces y_F = 53 from (26,35,44) alone — the Koide numerator is Möbius-determined by the three upstream corners (new exact cross-corner identity); honesty theorem: ℓ is affine on the path (step 9 = N²fam) and every linear functional passes — the check separates linear from nonlinear exports; negative controls with teeth: determinants fail at 28/25 as preregistered, the dominant eigenvalue fails at 1.3222; the DISCRETE half only — the continuous solver states stay open exactly as CONTRACT.F.01 fences them (9 checks, <1 s)

Different evidence answers different questions.

A numerical calculation, a formal theorem and an experimental comparison carry different kinds of information. Follow the source appropriate to the claim.

Python calculations: Inspect the algorithm, its inputs and its negative controls. Run a browser compatible module here, or use the repository for the complete environment.Browse Python sources
Formal mathematics: Read the actual Lean statement and its assumptions. The carrier formalization has a defined mathematical scope.Inspect the Lean formalization
Independent implementation: The Wolfram implementation checks algebraic results through a separate computational path. The recorded runs report 116/116 base checks and 603/603 extension checks. This is distinct from external experimental replication.Read the Wolfram implementation
Physical comparison: Read each prediction with its freeze, conditions and failure criterion. A passing mathematical check does not decide the experimental comparison.Open the prediction register

Run the same check on your machine.

From a checkout of the repository, install its Python requirements and run the first lattice module. The complete suite is a separate step.

Set up the repository

git clone https://github.com/sthamann/tfpt.git
cd tfpt
python3 -m venv .venv
