IRIS Repository Discover API (DSpace Discovery)

DSpace Discovery search across everything indexed in IRIS. Confirmed anonymous 200 on 2026-09-01, reporting a last page of 253,798 at size=1, i.e. 253,799 indexed objects. This matters because /core/items and /core/bitstreams both answer 401 to an anonymous client, so Discovery is the only callable route to item-level metadata over REST.
