The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

All seven new blazars are posterior-predictively consistent with this calibration (χ²_7 = 1.58, p = 0.98) under the working hypothesis that the published IceCube best-fit neutrino numbers n̂_s values reflect the signal. A flux-space permutation test on the 13-source joint sample rejects random pairing L_hX--L_ν with p = 6.3 × 10^{-4} (3.23σ).

C2weakest assumption

The working hypothesis that the published IceCube best-fit neutrino numbers n̂_s values reflect the actual signal rather than background fluctuations, as the null-injection test explicitly shows the consistency check cannot distinguish signal from selected-background origins with the current calibration sample size.

C3one line summary

Bayesian calibration of neutrino-hard X-ray luminosity relation on six AGN shows seven blazars are consistent, with joint permutation test indicating non-random association at 3.23 sigma.
