1. devices_connected (always on, never gated): a top-level /api/status field next to loop_lag = LIVE WS socket count from the heartbeat connection map (getConnectedCount), NOT devices.status='online' (which lags by the offline-timeout). The single most-glanced operational number, so it can't disappear when debug is off. Also dropped 4 dead per-poll COUNT(*) queries the route computed but never returned. 2. debug block behind an admin flag: new minimal app_settings KV table (none existed; ai_settings is per-workspace, white_labels is branding) + lib/app-settings.js (cached, refresh-on-write so status polls read a cached boolean, not a DB row). routes/status.js includes `debug` ONLY when status_debug_enabled is on (persisted value overrides the STATUS_DEBUG_ENABLED env default); when off the key is omitted entirely. 3. Admin toggle: GET/PUT /api/admin/status-debug (requirePlatformAdmin, mirrors the branding endpoints) + a checkbox in the Admin tab "Status endpoint" section (mirrors the branding checkbox). Takes effect on the next poll, no restart. Tests: devices_connected always present+numeric and rises with a live socket (booted + socket.io-client); debug present by default, admin flips OFF -> key omitted (loop_lag + devices_connected remain) -> ON again, no restart; non-admin 403, anon 401; unit coverage for getConnectedCount + app-settings default/override.
