rmancinasandClaude Opus 5 999717f77b feat: self-hosted remote support over VNC
Browser-based remote control (noVNC) with invite links, per-user access
control, garagedoor SSO and a persisted client list.

The hub proxies RFB rather than pointing the browser at a VNC server. That
is what lets it authenticate upstream with a stored password the browser
never sees, and enforce view-only by dropping input messages on the
client->server stream instead of hiding buttons.

Machines are reachable two ways: direct TCP for LAN hosts, or an outbound
agent tunnel for anything behind NAT. Node 22's global WebSocket keeps the
agent dependency-free, and node:sqlite keeps the image free of native
builds.

Ships with an end-to-end suite that boots the real server against a fake
VNC server and a fake auth service (72 assertions), plus Gitea Actions
CI/CD to Portainer.
