Opening a rectification Case used to switch sessions first and read the turns afterwards, so the reader saw a plain transcript, then an empty panel, then a remount when the turns arrived (and again after the first turn settled, because the panel key carried a ready/loading suffix). The surface hook now reads turns and snapshot in one Case request under the home reveal budget and only then makes the session active; the sidebar defers the switch the same way; a session selected at bootstrap (deep link, refresh) is hydrated during the prepare phase so the reveal shows the surface itself; the panel key is the session/Case binding only, later turns fill an empty transcript as a prop update, and unmounting aborts any stream or snapshot read. The homepage card and the sidebar row say 正在打开 statically while the Case opens — no spinner after the reveal.
