Theorem Packet v27 freezes a hierarchy: a universal compact / admissibility / local-residual layer, then a restricted bridge layer whose strongest draft is a covariance–variance coupling with a robust slope band and an explicit empirical validity region.\n\n\\Delta\\mathrm{Cov} = a_0\\,\\Delta\\mathrm{Var} + b_0 + \\varepsilon\n\na₀ and b₀ arise from baseline residual geometry; ε is controlled by gain drift, response curvature, and innovation scale. The operational default is a utility-maximizing stack; a balanced operating point is kept only as a softer interpretive alternative.\n\nBridge-closure status\n\nThe consolidated status note no longer treats the bridge as a loose hypothesis. It reports a hierarchical selector (not a flat one), real local seam structure, strong family and perturbation transfer, and a lower weak ladder from nested thresholding of a normalized retained-envelope variable.\n\nA retained-state bridge built from normalized residual-envelope coordinates supports a low-complexity hierarchical selector with real local seam structure, strong family and perturbation transfer, renormalizable scale behavior, and a lower weak ladder. This is the strongest admissible bridge claim — not TOE closure.\n\nV395 → V421 survival law\n\nA parallel compression: A_t = M_t × R_t was not enough. Immediate recovery did not predict delayed collapse or post-exit fidelity, forcing lineage addressability L_t and the recursive law S_t = M_t × R_t × L_t. V421 was a blinded generalization test (new topology, noise, fracture; no coefficient retuning). Greedy minimizers still win short-term bad rate; the retained law minimized harm, false exit, reclosure, lineage destruction, and long-horizon fidelity collapse.","howToCite":"Spradlin, A.
