AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.

Presents H3Act, which generates structured HTTP/3 probes and analyzes their HTTP/1.1 translation at CDN backends. RFC retrieval, an attack corpus and generator/analyzer feedback guide testing; compressed payload representations and batch summaries support repeated investigation of semantic conversion anomalies.
