# Graph Indexer Guild Charter (Epic 5)
|
||
|
||
## Mission
|
||
Project SBOM, advisory, VEX, and policy overlay data into a tenant-scoped property graph powering the SBOM Graph Explorer. Own ingestion pipelines, node/edge storage, aggregates, clustering, and snapshot lineage.
|
||
|
||
## Scope
|
||
- Service source under `src/Graph/StellaOps.Graph.Indexer` (workers, ingestion pipelines, schema builders).
|
||
- Mongo collections/object storage for `graph_nodes`, `graph_edges`, `graph_snapshots`, clustering metadata.
|
||
- Event consumers: SBOM ingest, Conseiller advisories, Excitator VEX, Policy overlay materials.
|
||
- Incremental rebuild, diff, and cache warmers for graph overlays.
|
||
|
||
## Principles
|
||
1. **Immutability** – Graph mirrors SBOM snapshots; new data creates new snapshots rather than mutating historical records.
|
||
2. **Determinism** – Given identical inputs, node/edge ids, hashes, and aggregates remain stable across runs.
|
||
3. **Tenant isolation** – Enforce isolation at ingestion, storage, and job levels; no cross-tenant leakage.
|
||
4. **AOC alignment** – Indexer links facts; it never mutates advisories/VEX/policy outcomes. Conseiller/Excitator/Policy Engine remain authoritative.
|
||
5. **Performance & telemetry** – Every job emits metrics (latency, node/edge counts, queue lag) and structured logs.
|
||
|
||
## Collaboration
|
||
- Keep `src/Graph/StellaOps.Graph.Indexer/TASKS.md`, `../../docs/implplan/SPRINTS.md` synchronized.
|
||
- Coordinate with SBOM Service, Policy Engine, Conseiller, Excitator, Scheduler, Web Gateway, and Console teams.
|
||
- Publish schema docs and fixtures for clients; share cost/identity conventions across services.
|
||
|
||
## Tooling
|
||
- .NET 10 preview workers (HostedService + channel pipelines).
|
||
- MongoDB for node/edge storage; S3-compatible buckets for layout tiles/snapshots if needed.
|
||
- Scheduler integration (jobs, change streams) to handle incremental updates.
|
||
|
||
## Definition of Done
|
||
- Pipelines deterministic and tested; fixtures validated.
|
||
- Metrics/logs/traces wired with tenant context.
|
||
- Schema docs + OpenAPI (where applicable) updated; compliance checklist appended.
|
||
- Offline kit includes seed data for air-gapped installs.
