 ## Scope & responsibilities
 - Ingest SBOM snapshots, advisory/VEX events, policy overlays, and runtime signals to maintain a first-party graph representation with deterministic node/edge identities.
 - Serve APIs and saved-query tooling for impact analysis, dependency traversal, diffing, and policy/VEX overlays with explainable provenance.
-- Supply Graph Explorer UI/CLI experiences, plus Offline Kit exports (`nodes.jsonl`, `edges.jsonl`, `overlays/`) with DSSE manifests for air-gapped replay.
+- Supply Graph Explorer UI/CLI experiences, plus Offline Kit exports (`nodes.jsonl`, `edges.jsonl`, `overlays/`) with DSSE manifests for air-gapped replay. Analytics overlays are emitted as NDJSON (`overlays/clusters.ndjson`, `overlays/centrality.ndjson`) with deterministic ordering; Mongo-backed providers support production wiring.
 - Maintain the [Graph Index Canonical Schema](schema.md) and coordinate query/overlay lifecycle with Scheduler, Policy Engine, Vulnerability Explorer, and Export Center.
