- add news-posts.external schema + sparse unique index on external.postUri - new backend module fetches trusted Bluesky accounts via app view and projects external link cards / facet links into news-posts - ac-news CLI gets a pull-bluesky subcommand for manual backfill - silo runs a periodic ingest loop (default 10m) + admin endpoints (/api/news/bluesky/status, /api/news/bluesky/pull) so future posts auto-appear in the headline list - SSR: external posts attribute to the Bluesky handle with a link to bsky.app and a source badge, still commentable via the usual AC flow
