# cv.atmos.feed.post

> A post that lives on Atmos and is not shown on Bluesky. It sits in the author's own repo and is public like every record there: any AT Protocol app can read it, but apps that do not know this type do not show it, so it does not appear on Bluesky. When the author shares it to Bluesky, an app.bsky.feed.post is written at the same record key and crosspost names it; the two records are one post. Treat crosspost as the link between them, never the shared record key alone, and only when crosspost.uri is an app.bsky.feed.post in the same repo (same DID) at the same record key as this record: consumers must ignore any other crosspost.
