…to distance-from-prior; rhyme #4 collapses into rhyme #1 (shadow*) Prover leg v2 of workitem 081KWT9WBPD08QG0R003H94RFE, executed on our side against Lumen's v2 map (from-lumen-self-dual-gap-v2.md, full-Hadamard gap). Shadow anti-entropy check verified before landing: AdinkraCode.isSelfOrthogonal (lines 77-79) literally asserts dot gi gj = 0 for all generator row pairs, so self-dual => all codewords mutually orthogonal is grounded in real code; the two-collapse kill follows by L2 permutation symmetry. Verdict: rhyme #4 v2 -> NOT a distinct physics theorem; COLLAPSES into rhyme #1 (distance-from-prior). Because the [8,4] code is self-dual, c_i.c_j = 0 for all 16x16 codeword pairs, so Lumen's H_ij = (1/16)(-1)^(c_i.c_j) is the rank-1 all-ones/16 matrix, Hpi = W_C for EVERY distribution, and G = ||pi - Hpi|| = ||pi - W_C|| = plain L2 distance from the uniform prior. All three v2 numbers match this degenerate formula to machine precision (point mass sqrt(15/16)=0.968; collapse sqrt(182/256)=0.843; reseed contraction exact 100/100). Claim 2 "resurrection" is an artifact and fails at its own job: two DIFFERENT single-codeword collapses (->A, ->B) give IDENTICAL G=0.843 - the degenerate G is blind to which codeword, the exact blind spot v2 set out to fix. The genuinely codeword-sensitive object is the full 256-dim Walsh transform on F_2^8 (182 units of energy live outside C-perp; the two collapses are Walsh-distance 19.8 apart there) - but Lumen did not compute it; it's an open re-derivation. Claim 1 trivially-true/degenerate (norm-definiteness, H rank-1). Claim 2 metaphor (unchanged from v1). Claim 3 theorem but generic (affine reseed + homogeneous norm, independent of Hadamard/self-duality). Repo §B open conjecture NOT discharged - v2 sidestepped it with a degenerate transform. Tool routing (BP-16): Z3 for all three (one-liners), NOT Lean (would false-green the degeneracy).

v2 prover leg verdict. The full-Hadamard gap degenerates: self-dual ⇒ all codewords mutually orthogonal ⇒ Lumen's 16×16 H is rank-1 (
Hπ=W_C∀π) ⇒G=‖π−W_C‖= plain L2 distance from the uniform prior. Lumen's numbers match to machine precision. Claim 2 'resurrection' is an artifact — two different single-codeword collapses give identical G=0.843 (blind to which codeword). Net: rhyme #4 collapses into rhyme #1 (distance-from-prior); one generic theorem survives (reseed contracts G by 1−1/N, but needs no Adinkra structure). The genuinely codeword-sensitive object (256-dim full Walsh) is uncomputed — open follow-up. §B not discharged.
