gw ringdown echocatalog-feasibility: a maximal (2/3)^6 echo would be reachable by a stacked strain search (stacked rho_echo ~ 6.3 >= 5) -> the strain-level test is worth running; no echo claim is made at catalog level

gw ringdown spectroscopystructural: ln3 = ln N_fam exactly and the area quantum is 4 ln3 = ln 81 = ln(N_fam^4); but the asymptotic omega_R/T_H=ln3 lives in the high-overtone limit, while measured ringdowns see the n=0 fundamental -> the black-hole-direct family-count test is DATA-LIMITED (needs high-overtone spectroscopy). [C]/[P]: Hod's '3' is spin-dependent, the N_fam identification is suggestive, not forced.

gw speed multimessengerconsistency (kill-test passed): the single-Lorentz-cone prediction (v_GW - c)/c = 0 sits inside the GW170817 bound; a measured v_GW != c would falsify the gravity closure. Not a detection (standard physics predicts the same).

higgs criticalitySM lands at lambda(M_Pl) = -0.0143 +/- 0.0057, beta_lambda(M_Pl) = +1.92e-04 (1-loop): remarkably close to the double-critical surface (lambda=0, beta_lambda=0). lambda sits 2.5 sigma below 0 -> metastable vacuum (matches the published ~2.8 sigma). Consistent with the TFPT near-criticality bridge; the verdict is dominated by M_t -- a sharper top mass is the discriminating input. Downstream RGE bridge [C], not a compiler output.

    lambda h0 engineconsistency: the EM fixed point alpha^-1 reproduces the measured Lambda hierarchy to 0.00 orders (122.95 predicted vs 122.94 measured) and H0/Mbar ~ e^-ainv/(2pi) to ~0.1 dex; the dimensionless identity S_dS rho_Lambda = 32 pi^4 is exact. One engine for Lambda, S_dS and H0 -- a consistency, not a parameter-free derivation of the absolute scale (the anchor).
