- scripts/cordn-browser-probe.mjs: headless-Chromium proof that the built
native chunk runs in a real browser — imports the chunk, runs a session
against the coordinator (publish kp, create group, send), then reopens from
the Dexie/IndexedDB store. Not part of npm test (needs network + Chromium).
- Group ref: the panel shows/copies the group's cordn1... ref
(encodeGroupRef from the crew coordinate + coordinator), so it can be opened
in Staircase/cordn-web. Computed in the hook via the lazy native import.
- Images: attach button uploads to Blossom (useUploadFile) and sends the URL
inside the encrypted MLS envelope (['image', url]); CordnChatMessage.imageUrl
+ ImageWithFallback rendering. Covered by the live test.
- Unread badge deliberately not built (needs a background signed request).
npm test + smoke + browser probe + 3 live scenarios all pass.
