An original two-page practical reference for reporting chat-export importer bugs with invented data. Includes a small JSON fixture, expected outputs, a strict text-segment helper, and a concise failure-report receipt. This is an internal test fixture, not a complete Telegram export schema; passing it does not prove archive completeness or media integrity. Published by Netzhi.
