#5467 "Steward's own health: metrics, rules can watch them, a page that shows them". The self-monitor tick now records, under source "steward", resource "process": ingest_posts / ingest_failed / ingest_slowest_ms (the host-agent posts since the last tick, tallied in steward/core/health.py), db_roundtrip_ms (a timed SELECT 1), and unwatched_secs (the gap before this tick past watch.GAP_S, from Steward's own last sample). The hourly cleanup records cleanup_secs. The open-file pair is still recorded, and is now only skipped on its own where /proc is absent. All of these are in CORE_METRICS, so an alert rule can watch them under "Steward itself". Settings → System (/settings/system/, admin) shows a verdict first (failed posts, a gap in watching, open files near the limit), then each measure now and over the last day, with a sparkline scaled to its own peak.
