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).
