coinosv3.git/tools/link-preview-test.js, branch fdroid-v1.9

Everything on the coinos relay is a feed of its own, and every feed can read from relays of your choosing.

Plain /feed is the firehose: every post relay.coinos.io carries, no filter. It sits beside Following as a built-in chip for wallets and opens as a session feed for a visitor. A feed's relay list is independent of what it asks for. The Relays button in the header opens a panel to add to or take from the list; empty means the usual choice (each author's outbox, the wide relays for a topic, the coinos relay for the firehose). The list rides in the URL as ?r=…, on every kind of feed, so a shared link reads where you read. A feed state dropped while its fetch was still out used to swallow the answers meant for its replacement; a relay change showed nothing.

Links in posts show as the cards their pages describe.

A plain link becomes an Open Graph card: picture, title, a line, the site. The registrar fetches the page on the reader's behalf (names/preview.js, GET /preview?url=): only public hosts, at most half a megabyte of HTML, cached a day. The client warms the card with the rest of the post so the row arrives whole, keeps a few hundred cards across sessions, and leaves a page with nothing to say as a bare link. Pictures and YouTube keep their boxes. Co-Authored-By: Claude Fable 5.1 Claude-Session: https://claude.ai/code/session_01VhUKyXKtsJ67QAFfb7QR9D
