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

Applying this framework to 15 repeating FRBs, we find that high-confidence RM flares are remarkably rare, with FRB 20220529A being the only source to exhibit a statistically significant event under standardized parameters.

C2weakest assumption

That the algorithmic framework can objectively isolate discrete transient perturbations from quiescent backgrounds and intrinsic environmental volatility despite complex behaviors and highly non-uniform temporal sampling.

C3one line summary

A new algorithmic framework detects rare RM flares in repeating FRBs, identifying only one statistically significant event in 15 sources studied.
