Telegram bot threaded mode

What I’m trying to do Use Telegram Private Chat Topics (BotFather Threaded Mode) so each topic in a DM is its own Vellum conversation — parallel threads for different workstreams — without breaking normal DMs that don’t use topics. Ideally titles stay in sync with the app, and I can fork/rename/profile from Telegram itself. What I tried / where I’m stuck Today everything in a Telegram DM collapses into one conversation. Enabling Topics in BotFather doesn’t help: replies ignore message_thread_id, so topics aren’t isolated. There’s no good way to fork a topic or rename it from Telegram (especially painful on iOS). I don’t want group forums or lifting DM-only — just private topics, with plain DMs unchanged. Desired shape (if we build it) No thread id → same as today With thread id → per-topic binding + replies in that topic /new scoped to topic or root DM; /fork + /rename topic-only (/rename guardian); /profile / /access for this chat/topic Title sync both ways (app ↔ Telegram)
