Release-cycle review found two move-path issues:
- Remote moves were placed at index:0 (broadcastPageMoved hardcodes index:0),
so every observer rendered the moved node at the TOP of its new siblings
until refetch. Client moveTreeNode now places by fractional position
(treeModel.placeByPosition, mirroring addTreeNode/insertByPosition) and
applies the payload's pageData (title->name, icon, hasChildren) so receivers
keep the node correct.
- Moving a page under a restricted ancestor left a stale named node (title/
slugId/icon) in the trees of users who lost visibility. broadcastPageMoved
now derives one FRESH hasRestrictedAncestor decision and drives both paths
from it: when restricted, the move goes to authorized users only
(emitToAuthorizedUsers, not the space-cache-gated emitTreeEvent) and a
compensating deleteTreeNode goes to the unauthorized complement (same fresh
getUserIdsWithPageAccess set) — disjoint, no stale-cache window. Non-restricted
moves are unchanged (one moveTreeNode to the room).
Follow-up (noted): invalidateSpaceRestrictionCache is still unwired at
permission-mutation sites; the open-space fast path can lag up to the 30s TTL,
but the move/delete consistency above no longer depends on it.

The sidebar page tree only updated on other clients when a change was made
via the UI tree, in an open tab, within a ~50ms client relay window — API/MCP/
AI/import changes never propagated. Move the source of truth to the server.
Server:
- Enrich PageEvent with thin TreeNodeSnapshot(s) so the WS listener never reads
the DB (avoids the in-transaction visibility race). insertPage fills the
create snapshot from its returning() row; removePage ships only the deleted
subtree ROOT (client treeModel.remove drops descendants); restorePage carries
spaceId.
- New PAGE_MOVED event from movePage with old/new parent + position + snapshot
(generic PAGE_UPDATED stays for content/rename).
- WsService.emitTreeEvent mirrors emitCommentEvent (per-space restriction gate:
spaceHasRestrictions -> hasRestrictedAncestor -> broadcastToAuthorizedUsers);
author NOT excluded so non-UI creators see their own page (receiver is
idempotent).
- WsTreeService.broadcastPageCreated/Deleted/Moved + broadcastRefetchRoot;
new PageWsListener (create/delete/move/restore) registered in WsModule.
Client:
- Remove the client relay (emit + setTimeout(50)) from create/move/delete;
keep optimistic local updates. Make the optimistic create insert id-idempotent
(find-then-skip) so the now-fast server addTreeNode broadcast can't race it
into a duplicate row. addTreeNode inserts by fractional position among loaded
siblings (consistent order across clients).
Restore uses refetchRootTreeNodeEvent (robust for subtree re-attach). Rename/icon
updateOne and cross-space move realtime are deferred (commented as follow-ups).
