stapel-video 0.2.0

Video calls (rooms, lobby admission, recording-egress seam) for the Stapel framework

stapel-video

Video calls for the Stapel framework — a thin, provider-agnostic library over a real-time video backend (LiveKit by default).

• Rooms with human-shareable join codes (abc-defg-hij).
• Admission model — public (anyone with the code joins), scope_trusted (members of the room's scope join instantly, others wait), restricted (everyone but the host waits in a lobby).
• Realtime lobby over WebSockets (Channels) — waiting / admitted / denied, authenticated by the same Stapel JWT stack HTTP uses.
• Host controls — admit / deny waiting guests.
• Provider seam — one VideoProvider ABC (mint join token, create room, start/stop recording egress, verify webhook). Swap vendors without forking.
• Recording is a seam, not a pipeline: start/stop_egress proxy the provider and a video.egress_ended comm event carries the storage key to stapel-recordings — by event, never by import.

Alpha (0.1.0). See MODULE.md for the agent-facing map of seams.
