Build a Yente Cross-Dataset Entity Resolution Tracer

Trace matching entity profiles across independent screening datasets using OpenSanctions Yente API. Consolidate disjointed jurisdictional sanctions records into unified analyst provenance dossiers.

Sanctions Quality Assurance Analyst

Ingest cross-jurisdictional screening alerts produced by a local yente matching instance.

Retrieve overlapping entity profiles and FollowTheMoney schema representations from distinct datasets.

Merge matching properties and identify divergent birth dates or aliases across lists.

Generate a consolidated entity profile documenting cross-dataset provenance and discrepancies.

A provenance tree view showing match lineage, raw upstream gazette references, and analyst commentary comparison.

Run a local yente Docker instance indexing standard OpenSanctions default dataset samples. Starter examples below are synthetic. They are not downloaded records.

OpenSanctions data toolkit Query yente match endpoints and FollowTheMoney entity properties to extract lineage metadata.

mastra-ai, pydantic, httpx. Mastra AI supports deterministic state machines and provenance step tracking across complex compliance workflows. Hosted language model to generate structured audit justifications.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Queries local yente instance using FollowTheMoney schema representations.

Extracts source dataset provenance identifiers and published timestamps.

Produces a signed reconciliation dossier documenting dispute resolution grounds.

Simulates sanctions review provenance. All entity mappings and datasets are synthetic or public test fixtures. Use mock external writes. Require human review before any real deployment.
