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.

Read the original description and evidence links

SEAM.S3.LTO.01: the EXPLICIT flat-band commuting-projector (local-topological-order) realisation of the S3 input -- advancing v424 sub-step (i) ('realise the raw seam as a Z/2-reflection commuting-projector LTO') from abstract existence to an explicit gap-protected quasi-local projector net carrying the Z/2 reflection and the mu4 clock. [E] FLAT-BAND PARENT: the flattened Bloch Q=h/|h| of v367's p+ip collar has Q^2=I (flat +-1 bands) and P=(I-Q)/2 is an exact projector EQUAL to the occupied ground-state projector -- a frustration-free commuting-projector parent with the same gapped ground state. [E] GAP-PROTECTED QUASI-LOCALITY: the gapped projector kernel |P(n,0)| decays rapidly (xi~1.14 at M=1, exp R^2=0.995, |P(20,0)|<1e-6), xi grows as the gap closes (2.7 at gap 0.02); the GAPLESS point decays as a clean power law |R|^{-2.1} (R^2=0.999, tail ~2e-4) -- locality needs the gap. [E] Z/2 REFLECTION + mu4 INHERITED: the flattened modular Hamiltonian K_flat=sign(K) inherits Theta K_flat Theta=-K_flat (BW/u_Theta=J) and [rho,K_flat]=0 (mu4) EXACTLY (sign is odd; rho commutes with any f(K)). [E] NEG CONTROLS: a side-even reflection gives 2||K_flat||!=0 (BW fails), an off-mu4 K mixing opposite-sign marks breaks [rho,sign(K)]!=0. [C]/[O] the chiral c_-=8!=0 (FHS Chern |C|=1) obstructs STRICT finite-range commuting-projector locality (Kapustin-Fidkowski; C!=0 forbids exp-localised Wannier), so the realisation is the quasi-local LTO net of NPW26; advances v424 sub-step (i), SEAM.EQUIV.01 stays [O]. Python-only (numpy).

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
