The admin operator filter was a free-text input that broke three ways at once: its visibility hangs off the query response (scope === "all") and its value is part of the query key, so every keystroke started a new query, data went undefined for the round-trip, and the input UNMOUNTED mid-keystroke (lost focus, list blanking that read as a page reload). Filtering also silently failed — the server matches the operator by exact username, so partial text matched nothing. - keepPreviousData on the shifts query: previous data (and scope) stays live during refetch, so filter controls never unmount and the list never blanks on preset/filter changes. - The filter is now a <select> of operators that HAVE shifts: the server returns the distinct list (signed z-reports + the open shift's holder) on GET /api/shifts, admin scope only — operators still can't see other names. Exact match by construction. Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
