StellaOps Graph
Graph module (upcoming) will power graph-indexed queries for SBOM relationships, lineage, and blast-radius analysis.
Responsibilities
- Model SBOM and advisory entities as a navigable graph.
- Provide APIs for dependency impact, provenance chains, and reachability analysis.
- Integrate with Scheduler/Policy for graph-driven re-evaluation.
- Expose tooling for offline explorers.
Domain highlights (Epic 5)
- Nodes: artifacts/images, SBOM components, packages/versions, files/paths, licences, advisories, VEX statements, provenance attestations, policy versions.
- Edges:
depends_on,contains,built_from,declared_in,affected_by,vex_exempts,governs_with,produced_by, each timestamped and tenant-scoped. - Overlays: policy verdict overlays, VEX consensus, runtime telemetry, and export-ready snapshots with diff support.
- Queries: reachability (
impact(graph, advisory)), blast radius (reverseDepends(component)), provenance timeline, saved query library with semantic zoom for Console.
Key components
- Planned services documented in implementation plan (to be delivered).
Integrations & dependencies
- SBOM Service / Cartographer for data ingestion.
- Policy & CLI for query surfaces.
Operational notes
- Pending — see implementation plan for staged milestones.
Backlog references
- DOCS-GRAPH-24-003 (architecture index) and SCHED-MODELS-21-001 tasks.
Epic alignment
- Epic 5 – SBOM Graph Explorer: deliver graph indexer, API, Console explorer, saved queries, overlays, and exports.
