Evidence acquisition
The atlas now separates events, testimony, and documents.
This lab defines the two evidence pipelines that should sit behind the map: oral-history testimony metadata from USC VHA and document provenance from the Krikor Guerguerian Archive. Both are handled with access notes, source URLs, target schemas, and seed files before any record is promoted to the atlas.
Testimony metadata layer
USC Shoah Foundation Visual History Archive
The VHA branch is designed as a metadata-only testimony layer until authorized public metadata or institutional export is available.

Document provenance layer

The Guerguerian branch is built for document-level provenance: telegrams, officials, places, dates, languages, citations, and archive divisions.
