TNO Threading (draft):
Each origin feed numbers new threads (tno:N). Replies carry both (tno:N) and (ofeed:<origin-url>). Thread identity = (ofeed, tno).

• Roots: (tno:N) (implicit ofeed=self).
• Replies: (tno:N) (ofeed:<url>).
• Clients: increment tno locally for new threads, copy tags on reply.
• Subjects optional, not required.

...

Example:

Alice starts thread #42:

2025-09-25T12:00:00Z (tno:42) Launching storage design review.

Bob replies:

2025-09-25T12:05:00Z (tno:42) (ofeed:https://alice.example/twtxt.txt
) I think compaction stalls under load.

Carol replies to Bob:

2025-09-25T12:08:00Z (tno:42) (ofeed:https://alice.example/twtxt.txt
) Token bucket sounds good.

This is possibly the only other threading model I can come up with for Twtxt that I think I can get behind.

@movq Yes it's kind of terrible 😞 -- Let's not do this 🤣
