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.

CELEST.WP5DB.01: WP5d-beta of the celestial-holographic research contract CELEST.SEAM.01 -- 'split + strong additivity from the lattice', the two remaining KLM legs of complete rationality (split + strong additivity + finite mu-index; the index is v501). numpy/scipy Gaussian machinery + exact GF2/integer algebra; the U(1)/Dirac number-conserving subnet = the preregistered negative control. [E] STRONG ADDITIVITY ALGEBRAICALLY EXACT: 'touching' = shared boundary Majorana => Even(A) v Even(B) = Even(A u B) EXACTLY (GF2 spans full 64/64, 256/256, 512/512, 1024/1024; matrix rank 32/32); disjoint exactly half (rank 16/32, index 2 -- the missing sector odd(x)odd = the ln-2 bit of v501, localised at the split point); U(1)/neutral algebras do NOT generate the union even WITH the shared site (gaps 2/10/52 growing). [N] ENTROPIC WITNESS: fermionic touching MI diverges with exact (c/3)ln2 increments (0.115525, dev 1.2e-6 -- pure UV reference); the Z2/orbifold sector-sum deficit is BOUNDED < ln 2, monotone, (ln2 - Delta_2) ~ N^(-p) with p = 0.2444 vs 2 Delta_mu = 1/4 (Ising disorder exponent); split-point scan reflection-symmetric 3.9e-14; ED vN same direction; gap continuity to the v501 x -> 1 endpoint; honest note: 'defect -> 0' would be FALSE at the sharp lattice split -- bounded <=> finite index (Longo-Xu) is the correct statement; U(1) CONTRAST: D_U1 bursts ln 2 from L = 128 and grows as (1/2) ln Var Q_A (Klich-Levitov 0.10134 vs 1/pi^2 = 0.10132). [N] SPLIT/NUCLEARITY: sigma_k of the off-diagonal block fall exponentially with rate = elliptic nome pi K(1-x)/K(x) to 1.3-2.0% (d = 16/64/256/512: rates 2.29/3.24/4.82/5.81); sigma_1 ~ x^0.5044 (vs 1/2, the dimension-1/2 two-point law); trace norm summable, falling (Buchholz-Wichmann proxy). [E] ORBIFOLD INHERITANCE EXACT: P_A: C -> -C (sigma_k identical 8.3e-17); the even-bilinear coupling Gram = the second compound Lambda^2 C with singular values {sigma_a sigma_b} (2.8e-14) -- same ladder, doubled rate; orbifold MI < 3% of the fermionic, falling (Longo heredity [C]). [E] PIMSNER-POPA: E(a) - a/2 = PaP/2 IDENTICALLY => lambda = 1/2 = 1/[F:F_even] EXACT; attainment in integers (all 16384 monomial pairs N = 8: 8192 extremal with M^2 = 4/Tr M = 0/PMP = -M, 0 violations; N = 12: 2048/2048; random pencil min lambda = 0.5000000000); two-interval group lambda = 1/4 = 1/mu exact; INDEX CONSISTENCY of two routes (exp(Delta) = 2.000000000 = 1/lambda_PP; exp(2 Delta) = 4 = 1/lambda_E4 = mu). [E/N] NEGATIVE CONTROLS: U(1) PP lambda = 1/(m+1) -> 0 (infinite index); dimerised trivial (deficit N-independent 3.6e-15, sigma_1 exponential); U(1) small-L honesty; Z2 finite-size honesty (14.9% below ln 2 at N = 4096 -- witness, not proof); wrong prescription {1, P_AB}: deficit exactly 0. [C] the lattice -> continuum KLM dictionary (Longo-Xu, CHMP, Longo heredity). [O] the continuum theorem 'finite-group orbifolds of completely rational nets are completely rational' is XU'S THEOREM -- cited, not claimed; the proof for the concrete seam quotient net and the interacting condensed (E8)_1 net stays WP5e/Costello-Li; SEAM.EQUIV.01 stays [O]. VERDICT: with v501, all THREE KLM ingredients of complete rationality are witnessed on the lattice.

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
