The unified Lines view used to rebuild fleet-wide on every call — lines.get included a full rebuild plus a linear scan for a single hash. A small cache now holds the built groups and a line_hash_id index, rebuilt only after explicit invalidation: inventory ingest, proxy inbound/user/profile writes, node writes, vpn-core identity mutations, and apply outcomes. A 60s TTL is the documented safety net for a missed edge path; operator-driven mutations all invalidate explicitly, so the UI never reads stale after its own actions.
