Oh, the tree is still there. It's just flatter :)

In Pinthe coding agent, each transcript entry is parented to another entry. That was actually exceptionally dumb.

If you do /tree in pi, pi needs to flatten that tree into linear, nested conversations.

In Pi Durable, we corrected this mistake. A conversation is a chronological, immutable list of entries. A conversation can be parented to an entry in another conversation, and thus inherits that parent's older conversation entries starting from that entry.

So, exactly the same functionality, just less dumb.
