// `wsId` is used only as part of queryKey for cache isolation per workspace.
// The actual workspace context comes from ApiClient's X-Workspace-ID header,
// which is set by useWorkspaceStore.switchWorkspace(). Callers must ensure the
// header is in sync with the wsId they pass here — otherwise cache writes will
// be misattributed during a workspace switch race window.
