One thread of the inbox list. Showing it sends nothing: the inbox snapshot
already carries the preview (thread_message_limit=5 on both the 448 and the
451 recordings), and no recording shows a per-thread request fanning out as
the list appears. open opens the thread with the thread's own v2 id.
The edge takes the next ordinal: the 451 group recording goes
direct_inbox:2 → direct_thread:3:inbox — the clean transition, no screen
in between. The one-to-one recording's thread is 5 because that session
had already consumed two ordinals before the scene starts; that is the
scene's session history, declared by the scene, not a fact of this edge.
