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.

Seam parity census

Read the original description and evidence links

SEAM.MU.01: the T^2 spin-structure fermion-parity census for the v367 seam lattice model -- the lattice ground-state witness of 'mu_pre = 4 before condensation' (step 1 of the v378 KLM chain) + the 16-fold-way bridge theta_v = 1 with the measured nu = 2 c_- = 16 (v489). Parity per sector (AA, AP, PA, PP) determined twice: Read-Green TRIM product AND real-space Majorana Pfaffian (Schur), relative to the trivial phase. [E] sanity: twisted real-space spectra == Bloch bands to 9e-15. [E] per-layer census (+,+,+,-), TRIM == Pfaffian in every sector (3 even sectors = Ising nu = 1). [E] 16 layers: parity^16 = + in ALL 4 sectors => gauged torus GSD = 4 = mu(SO(16)_1) = |det Cartan(D8)|. [E] theta_v = exp(2 pi i nu/16) = 1 exactly at nu = 16; rivals nu = 1, 2, 8 excluded. [E] fence: fermionic Kitaev-Preskill TEE = 0 for BOTH M=1 and M=3 -- does NOT discriminate (E8)_1 vs SO(16)_1. [C] KLM step 4 -> 4/2^2 = 1 cited (interacting, not free-fermion computable); numerics pin only {c_- = 8, mu_pre = 4, theta_v = 1}. [O] continuum limit (MMST v336); SEAM.EQUIV.01 stays [O].

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
