# StellaOps VEX Consensus Lens

VEX Lens computes deterministic consensus across conflicting VEX statements while preserving raw provenance.

## Responsibilities
- Ingest VEX evidence from Excititor and align it to SBOM inventory.
- Apply issuer trust weights, freshness rules, and policy-defined tie breakers.
- Publish consensus snapshots and disagreement metadata for Policy Engine and Explorer surfaces.
- Expose APIs for explainability and offline bundle exports.

## Key components
- Consensus computation service and job pipeline.
- Consensus store with versioned snapshots.
- Explain trace generator for disagreements.

## Integrations & dependencies
- Excititor for raw VEX ingestion.
- Policy Engine for applying consensus in suppression flows.
- Vulnerability Explorer and Advisory AI for evidence overlays.

## Operational notes
- Trust model configuration and issuer scoring dashboards.
- Offline kit packaging of consensus snapshots.
- Telemetry on issuer coverage and disagreement counts.

## Epic alignment
- Epic 7: VEX Consensus Lens.
- Lens implementation stories tracked in ../../TASKS.md.
