# StellaOps Excititor

Excititor converts heterogeneous VEX feeds into raw observations and linksets that honour the Aggregation-Only Contract.

## Responsibilities
- Fetch OpenVEX/CSAF/CycloneDX statements via restart-only connectors.
- Store immutable VEX observations with full provenance.
- Publish linksets and events that drive policy suppression decisions.
- Provide deterministic exports for Offline Kit and downstream tooling.

## Key components
- `StellaOps.Excititor.WebService` scheduler/API host.
- Connector libraries under `StellaOps.Excititor.Connector.*`.
- Normalization helpers and exporters in `StellaOps.Excititor.*`.

## Integrations & dependencies
- Policy Engine for evidence queries.
- UI/CLI for conflict visibility and explanation.
- Notify for VEX-driven alerts.

## Operational notes
- MongoDB for observation storage and job metadata.
- Offline kit packaging aligned with Concelier merges.
- Connector-specific runbooks (see `docs/modules/concelier/operations/connectors`).

## Backlog references
- DOCS-LNM-22-006 / DOCS-LNM-22-007 (shared with Concelier).
- CLI-EXC-25-001..002 follow-up for CLI parity.

## Epic alignment
- **Epic 1 – AOC enforcement:** maintain immutable VEX observations, provenance, and AOC verifier coverage.
- **Epic 7 – VEX Consensus Lens:** supply trustworthy raw inputs, trust metadata, and consensus hooks for the lens computations.
- **Epic 8 – Advisory AI:** expose citation-ready VEX payloads for the advisory assistant pipeline.
