Original claim text

DERIVING THE CUSP WEIGHT 2/3 FROM A MINIMAL REWRITE (2026-06-22, sharpening HYP.FIBER.01/v324 + HYP.INJECT.01/v312). A minimal local rule -- a family channel with N_fam=3 slots, one absorbing attractor (w=0) and |Z2|=2 surviving (the Z2 pair) -- supplies the cusp fiber. [E] MINIMAL REWRITE: M=[[1,0,0],[0,1/3,1/3],[0,1/3,1/3]] has spectrum {1,2/3,0}; the recovery survival 2/3=(N_fam-1)/N_fam=|Z2|/N_fam EMERGES from the rule arity, not injected. [E] RECOVERY RATE DERIVED: over the order-6=2 N_fam dynamic hand the rate is (2/3)^6=64/729 = the recovery gap (v76/v324), derived not put in. [E] NON-GRAPH-SPECTRAL (proof, sharpening v312): 2/3 is NOT a root of the affine-E8 charpoly x(x^2-4)(x^2-1)(x^2-x-1)(x^2+x-1) (p(2/3)=-3520/19683 != 0), so the recovery rate cannot be an adjacency eigenvalue -- necessarily the branching channel. [E] ATTRACTOR: the absorbing state (eigenvalue 1) is the democratic w=0 law (v317). [O] HONEST RESIDUAL: the rewrite DERIVES 2/3 from the arity {|Z2|,N_fam}={2,3} (the anchor atoms, still the input P2/v23) -- v324's injected datum REDUCED to the anchor arity, not derived from nothing. UPDATE 2026-07-15 (v486/HYP.REWRITE.02): the uniform rule is the DEGENERATE case (spectrum {2/3, 0}); the unique lazy Z2-pair walk (stay 1/2, hop 1/6, leak 1/3) generates the FULL physical spectrum {1, (2/3)^6, (1/3)^6} over the same order-6 hand -- the (1/3)^6 mode now has a local-rule origin; superseded as full-spectrum generator, the 2/3 arity story unchanged.

Original classification detail

[E] the rule spectrum {1,2/3,0} + the recovery-rate derivation (2/3)^6 + the non-graph-spectral PROOF p(2/3)!=0; [O] the arity {2,3} is still the anchor input. Sharpens v324/v312 (the injected datum reduced to the anchor arity); not a derivation of the atoms.

    Deriving the cusp weight 2/3 from a minimal rewrite (sharpening v324/v312). A minimal local rule -- a family channel with N_fam=3 slots, one absorbing attractor (w=0) and |Z2|=2 surviving -- supplies the cusp fiber. M=[[1,0,0],[0,1/3,1/3],[0,1/3,1/3]] has spectrum {1,2/3,0}; 2/3=(N_fam-1)/N_fam=|Z2|/N_fam EMERGES from the rule arity, not injected. Over the order-6=2 N_fam hand the rate is (2/3)^6=64/729 = the recovery gap (v76/v324), derived. NON-GRAPH-SPECTRAL (proof, sharpening v312): 2/3 is NOT a root of the affine-E8 charpoly (p(2/3)=-3520/19683 != 0), so the recovery rate cannot be an adjacency eigenvalue. The absorbing state (eigenvalue 1) is the democratic w=0 law (v317). Honest residual: the arity {2,3} (the anchor atoms) is still the input (P2) -- v324's injected datum reduced to the anchor arity. Substrate = (2,3,5)-adjacency (carrier) x this minimal branching rule (family).
