How we check sources
Not checked yet
- The route is a public2025-12-31 Rider Institute compilation, not independently authenticated original AFHRA receipt. Original reel, full context, fine handwriting and signature authentication remain gaps. Typewritten attribution and historical stamps are not independent authentication.
- An instruction to make arrangements is not evidence that an interrogation occurred or that access, custody or a technical programme was achieved. The compiler’s proof caption is its interpretation; no resulting interview report is supplied.
- Only this dated letter unit and the separately defined August report were read from D8. The104-page compilation is not completely read. Its reuse in later accounts does not establish additional independent witnesses.
