Back to the connections

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.S3.LOCALITY.01: the Kapustin-Fidkowski/Thouless strict-locality OBSTRUCTION made explicit -- sharpening v460's verdict from a cited statement to an exhibited topological obstruction. [E] CHERN INTEGER: the FHS Chern of v367's p+ip collar = +1 (chiral M=1), 0 (trivial M=3), -1 (opposite mass). [E] WILSON-LOOP / WANNIER-CENTRE WINDING = CHERN: the hybrid Wannier centre theta(ky) winds by |C|=1 (chiral) and 0 (trivial) over the BZ -- exp-localised Wannier exist IFF winding=0 (Brouder et al.), so the chiral collar has NO exp-localised Wannier basis. [E] OBSTRUCTION INTEGERS TIED: winding=|C|=1!=0 and c_-=16/2=8=g_car+N_fam=rank E8!=0. [E] NEG CONTROL: BOTH phases gapped, yet only the trivial (winding 0) admits exp-localised Wannier and a strict finite-range commuting projector -- it is the CHIRALITY, not the gap. [C]/[O] a strictly finite-range commuting projector would force winding 0, C=0; since C=1!=0 none exists, so v424 sub-step (i)'s realisation is PROVABLY the quasi-local NPW26 LTO net; SEAM.EQUIV.01 stays [O]. Python-only (numpy).

Linked claims

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
.venv/bin/pip install -r requirements.txt

Check the E₈ lattice

.venv/bin/python verification/v1_e8_glue.py

Read the individual checks and the final pass or fail result.

Run the registered suite

cd verification
../.venv/bin/python run_all.py

The full suite uses the dependencies and source context documented in the repository.

Repository setup and maintenance instructions

Read the current claim beside its source.

The research snapshot dated 2026-11-02 includes the active ledger, reviewed findings and registered scripts. It records source coverage and stated scope; it is not a new execution of every proof or calculation.

Trace the dependencies.

Select a node to inspect its inputs, outputs, scope and verification scripts. Browser compatible checks open the same verification viewer; native certificates provide their local command.
