social.skyphone.video ยท 2- social.skyphone.video.meta record Mutable metadata sidecar for a video. Record key MUST match the rkey of the social.skyphone.video.post record in the same repo, so a reader that holds a video record can fetch its metadata with one getRecord. Editing metadata is a put on this record; the canonical video record stays untouched.
- social.skyphone.video.post record Canonical video record. The video blob and durationMs MUST NOT change after creation; replacing the video requires a new record. This record intentionally carries no human-readable metadata: title, description, thumbnail and the announcement post live in a social.skyphone.video.meta record with the same record key in the same repo.
