The desktop page has never worked on a fresh install. Two faults, both fatal.
The password could never be created. DesktopView fetches /desktop/vnc-password
before opening the WebSocket, but ensureVncPassword ran only from startSession,
which only the WebSocket triggers — so the endpoint answered "not configured",
the UI stopped, and the socket that would have provisioned it was never opened.
A new vnc:ensure-password sidecar command provisions it directly; the endpoint
asks for it instead of returning 500.
The rfbauth file could never be written either. ensureVncPassword shelled out to
tigervnc's `vncpasswd -f`, which is not installed — and, contrary to the comment
in setup-desktop.sh, is not in tigervnc-common, which ships only tigervncconfig.
The failure was swallowed because only a zero exit wrote the file, so x11vnc got
-rfbauth pointing at nothing. x11vnc writes that format itself with -storepasswd,
so the dependency is gone and a failure now throws.
Verified on the box: the endpoint returns a password, .vnc/{passwd,password} are
written 0600, and the sidecar reports mirroring :0 on 5900 with x11vnc using the
generated rfbauth file.

The VNC sidecar builds its .vnc/passwd rfbauth file with `vncpasswd -f`
(vnc-manager.ts) — x11vnc alone doesn't ship vncpasswd. The GNOME-on-Xorg
rewrite dropped tigervnc, so the mirror couldn't create its password and
/desktop failed with "VNC password not configured". Add tigervnc-common back.

setup-desktop.sh now installs ubuntu-desktop + gdm3 + x11vnc and forces the
Xorg session (WaylandEnable=false) with auto-login — x11vnc can only mirror an
Xorg :0, not Wayland. vnc-manager.ts resolves the X authority from the GDM
per-session path (/run/user/<uid>/gdm/Xauthority) with a ~/.Xauthority fallback.
setup.sh fixes:
- desktop step gates on `dpkg -s ubuntu-desktop` (was the decommissioned
officer-vnc service, which never matched so setup-desktop re-ran every time)
- remove Pi (install, --list-models validation, verification check)
- export GOPATH before the cliamp build so `go install` lands where it's checked
even when Go was already present this run
- write PUBLIC_BUILD_ENV=production and quote all .env values
- guard the interactive .env block behind a TTY check so non-interactive runs
skip cleanly instead of aborting on read EOF under set -e
- restart systemd-logind only when a key actually changed
- sed prefix-strip instead of `tr -d` (which deletes characters, not a prefix)

replaces the single hardcoded systemd VNC service with a dynamic
sidecar that manages per-user VNC sessions on demand. any authenticated
user can now access their own desktop, not just Super Admin.

- Added detailed error logging to detect snap node compatibility issues
- When Pi process exits with code 1, log helpful diagnostic info including node path
- Add hint to check for snap node and reinstall via apt/nvm
- Create SNAP_NODE_COMPATIBILITY.md with full troubleshooting guide
- Document root cause: snap node has file descriptor incompatibility with Bun.spawn stdin pipes
- Provide clear installation instructions for NodeSource and nvm alternatives
