Module thread 

Message threading after JWZ’s algorithm (https://www.jwz.org/doc/threading.html): containers per message-id, reference chains linked parent→child with loop protection, empty containers pruned by promoting their children. Threads and siblings are ordered by date. Subject grouping (JWZ step 5) is not done.

Structs

ThreadOrder

Like thread, ordering threads by their newest message when newest (mutt’s sort_aux = last-date-sent). How the threads themselves are ordered, from mutt’s $sort_aux: by the root’s date or by the newest message under it, oldest first or newest first.

ThreadedItem

One index entry in thread order.
