This reverts commit 39528edd74.
That push was an accident: the fs-import fix it described had already landed
on main, and a rebase reduced the commit to unrelated in-progress
gateway-protocol schema edits (nodes/session-placement) that were staged in
the pushing worktree and belong to another work stream. Restore the reviewed
main state; the protocol work can land through its own PR.
