DEF CON2–5: documented coverage gaps
The catalog has no imported records for these four editions. That is a source-access and indexing gap, not evidence that no talks occurred. Expected historical counts remain unknown.
Published 16 October 2026 · JSON · TXT
The permitted secondary indexes contained no presentation or presenter entries in this inspection. Official pages were not fetched because their robots policy disallowed OpenAI agents. No bypass was attempted.
Current conference totals:12,394records;9,796with credits. This does not establish historical completeness.
