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

the method reveals localised tracking failures that are invisible to conventional channel-level diagnostics

C2weakest assumption

A reference track helix can be extrapolated accurately to each wire layer and hits can be associated without significant bias from the tracking algorithm or reconstruction

C3one line summary

A new diagnostic creates per-wire efficiency plots for the Belle II CDC by extrapolating helix reference tracks and measuring the fraction of expected crossings with associated hits.
