Conference coverage and gaps

Expected total historical talks: unknown. Counts below describe imported source records only. Source lists were discovered and imported; not every underlying recording, slide or speaker identity was independently verified. Thirty DEF CON 1/6 records have separately checked talk-specific credits. Source-provided credits are not an independent verification count.

DEF CON 2–5: independent indexes have no data; official archive retrieval stopped because its robots policy disallows OpenAI agents. This does not mean no talks existed. No bypass was attempted.

HOPE: 14 edition lists imported, with 1994/1997/2012 still absent. CCC: Congress 17–39, seven Camps, GPN and selected other events; recording catalog coverage differs from program coverage. Ninety Black Hat research rows/groups have event-year/date conflicts and remain labeled.
