## 2) Pipelines
1. **Ingestion:** Cartographer/SBOM Service emit SBOM snapshots (`sbom_snapshot` events) captured by the Graph Indexer. Ledger lineage references become `SBOM_VERSION_OF` + `SBOM_LINEAGE_*` edges. Advisories/VEX from Concelier/Excititor generate edge updates, policy runs attach overlay metadata.
2. **ETL:** Normalises nodes/edges into canonical IDs, deduplicates, enforces tenant partitions, and writes to the graph store (planned: Neo4j-compatible or document + adjacency lists in Mongo).
2. **ETL:** Normalises nodes/edges into canonical IDs, deduplicates, enforces tenant partitions, and writes to the graph store (planned: Neo4j-compatible or PostgreSQL adjacency lists).
3. **Overlay computation:** Batch workers build materialised views for frequently used queries (impact lists, saved queries, policy overlays) and store as immutable blobs for Offline Kit exports.
4. **Diffing:** `graph_diff` jobs compare two snapshots (e.g., pre/post deploy) and generate signed diff manifests for UI/CLI consumption.
5. **Analytics (Runtime & Signals 140.A):** background workers run Louvain-style clustering + degree/betweenness approximations on ingested graphs, emitting overlays per tenant/snapshot and writing cluster ids back to nodes when enabled.
