api for establishing run -> library ->biosample linkage (no metadata reveal)

[dkj]

At the moment we use the api/v2/process/sequencing/get/ (with run_name) to confirm that we have linked run to library to biosample and also to establish whether or not the biosample has been properly registered (with minimal metadata).

We'd like this functionality from the API without the exposure of actual metadata so that we can request long-lived refresh tokens for a non-metadata-revealing OAuth scope.

(Happy to do a two stage lookup with api/v2/artifact/biosample/query/validity or v3 equivalent if a new <something>/sequencing/get/ were to return run -> library -> biosamples[sample_id1,sample_id2,...] )
