# StellaOps Concelier

Concelier ingests signed advisories from dozens of sources and converts them into immutable observations plus linksets under the Aggregation-Only Contract (AOC).

## Responsibilities
- Fetch and normalise vulnerability advisories via restart-time connectors.
- Persist observations and correlation linksets without precedence decisions.
- Emit deterministic exports (JSON, Trivy DB) for downstream policy evaluation.
- Coordinate offline/air-gap updates via Offline Kit bundles.

## Key components
- `StellaOps.Concelier.WebService` orchestration host.
- Connector libraries under `StellaOps.Concelier.Connector.*`.
- Exporter packages (`StellaOps.Concelier.Exporter.*`).

## Integrations & dependencies
- MongoDB for canonical observations and schedules.
- Policy Engine / Export Center / CLI for evidence consumption.
- Notify and UI for advisory deltas.

## Operational notes
- Connector runbooks in ./operations/connectors/.
- Mirror operations for Offline Kit parity.
- Grafana dashboards for connector health.

## Backlog references
- DOCS-LNM-22-001, DOCS-LNM-22-007 in ../../TASKS.md.
- Connector-specific TODOs in `src/Concelier/**/TASKS.md`.

## Epic alignment
- **Epic 1 – AOC enforcement:** uphold raw observation invariants, provenance requirements, linkset-only enrichment, and AOC verifier guardrails across every connector.
- **Epic 10 – Export Center:** expose deterministic advisory exports and metadata required by JSON/Trivy/mirror bundles.
