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.EQUIV.CROSSEDPRODUCT.01: the net-level crossed-product certification of the 128-spinor extension + the R1 -> R1' invariant reduction. [E] LR LOCALITY INTEGER: h_s(SO(16)_1) = 16/16 = 1 in Z => statistics phase +1 -- the Longo-Rehren criterion HOLDS, the Z2 simple-current crossed product is a LOCAL index-2 extension (LR RMP 7 (1995); Boeckenhauer RMP 8 (1996); BE CMP 197 (1998)); KLM mu = 4/2^2 = 1 => holomorphic => (E8)_1 (v463 pin, E4/eta^8 q^1 = 248). The AGT/AMT 2024/2025-preprint leg (v459) DEMOTED to independent second witness -- the extension now rests on 1995-2001 peer-reviewed journals. [E] index-4 parallel: mu4 glue h(J^k) = {1,1,1} all integer (= v125 isotropy at net level), mu = 16/16 = 1. [E] R1' invariants computed: FHS Chern 1/0, nu = 16, c_- = 8; nu mod 16 = 0 = the Kitaev-E8 class (16-fold way). [E] chain T1->T4 composes (Kitaev/Kapustin-Spodyneiko -> MMST+Boeckenhauer -> LR/BE+KLM -> Dong-Mason+v463). [C] R1 -> R1': collar_realizes replaceable by collar_invariants (quasi-free [C] + gap [E] + class D + c_-=8 [E from P1]); quasi-freeness stays the ONE [C]. [O] SEAM.EQUIV.01 stays [O]. Mixed exact (Wolfram-mirrored) + numerical (FHS Chern).

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
