 ## [Unreleased]
 
 - Split Cockpit camera/controller, instruments, briefing, signals and layout into focused modules with explicit application operations.
-- Give Display portal moves cancellable focus/scroll restoration and terminal cleanup.
+- Give Display portal moves cancellable focus/scroll restoration and stop Cockpit work before asynchronous UI teardown.
 
 - Separate Context controls, mode transitions and layer restoration; release tab listeners and suppress late panel/search feedback after disposal.
