The real-time release — phase 2 of the roadmap.
- Hocuspocus server + Yjs bridge plugin.
- Room lifecycle — create on upload, GC after TTL.
- Share URL — anyone joins. Password-protected rooms with SHA-256 client gate.
- View-only role enforced at the Univer engine layer.
- Redis persistence (optional, 7-day TTL).
- Joiner fast-path — gzip-streamed snapshot, skips xlsx parse.
- Op-log compaction (Stage 6) for long-lived rooms.
- Self-hosted Docker image — web + Hocuspocus + Fastify in one container, single port.
