New eprints publish a site.standard.document record, so @standard.site readers can pick them up. Sharing an eprint to bluesky also records the post on that document, which makes the reply thread findable from the paper. You can now post an event with @smokesignal.events or anything else using community.lexicon.calendar.event, list the eprint among its URIs, and the paper shows where it was presented. @tangled.org repositories can now be referenced by at-uri rather than by URL.
