Two conflicts:
- .gitignore — both sides added doc negations; kept both.
- orchestration/db.ts — this branch moved `isEquivalentPaneKey` into
shared/stable-pane-id (collapsing a duplicate), while main added
`parseWorkerTerminalPriorOwnerIds` beside the old local copy. Kept the move
and kept main's new helper, rather than resurrecting the duplicate.
43,250 pass. The 7 failures are the same environment-specific pre-existing ones
(osc8 snapshot round-trip, IME resumed-preedit) that fail on clean origin/main
in this environment.
