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 reported results highlight the remaining challenges of robust audio deepfake detection under multilingual and media-transformed conditions.

C2weakest assumption

The constructed dataset and chosen media transformations accurately represent the distortions that occur in real-world audio distribution pipelines.

C3one line summary

The RADAR Challenge 2026 provides a multilingual benchmark for audio deepfake detection under media transformations and finds that robust performance remains an open problem.
