A Signal Desk desk is built from its operator's own data. Every signal shows the source record it stands on.
An operator delivers their own datasets to their desk: by API, from a storage bucket, by file drop or SFTP, or by upload. A desk states where each feed comes from: the supplier, the path it travelled, and its last delivery. Readers see that on the desk's own Data and provenance page.
A desk's data is served on that desk, to the people its operator invited. It does not enter DRM3 commons search, another desk, or a data pack.
When an operator adds DRM3's public record, those sources are open data. Each one is listed with its license in the DRM3 data-license registry. Where a source asks for attribution, we carry it.
Signal Desk derives its signals with AI. Every signal says so, and that label cannot be removed. A signal is a reading of a record. The source record is the authority: read it before you act on a signal.
