get_relations now accepts an optional 'types' (comma-separated) parameter to filter relationship types — filters out the noisy exec/targets edges that previously drowned useful host/provides edges. get_health_summary now accepts an optional 'health' (comma-separated) parameter to return only entities in specific health states (e.g. 'health=down,stale') instead of the full 100+ entity list. ping_service now: - Falls back to e.attributes->>'public_host' when 'url' is not set (covers LXCs that only have public_host in the graph) - Performs a live HTTP HEAD probe against the resolved URL, returning the actual status code instead of just the scheduler's stale health state Also: fixed matrix.hubris.network DNS record (was pointing to dead VPS), pruned 6 dead graph edges, wired url attributes on 7 LXCs, added VPS HTTP monitoring check, and resolved the 18k-occurrence unmonitored signal. This session's audit is documented as document:nomos/2026-08-05-dns-monitoring-improvements-for-strong-hosted-services.
