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

These findings demonstrate that current disinformation detectors may systematically disadvantage hundreds of millions of non-SAE speakers worldwide.

C2weakest assumption

The Multi-VALUE transformations produce dialectal variants that accurately reflect real-world usage and preserve the original disinformation label without introducing confounding artifacts that independently affect model performance.

C3one line summary

DIA-HARM reveals that human-written dialectal English degrades disinformation detector F1 by 1.4-3.6% while AI-generated dialectal content stays stable, with multilingual models generalizing better than monolingual ones.
