The repo's own .env now exists for other settings; grepping it for a token it doesn't have killed the script silently under pipefail, so a reinstall never reached the homelab .env. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# The sidecar must run natively on the host (not in Docker) as the repo owner so

# the `claude -p` sessions it spawns use the real ~/.claude auth, hooks and

# skills. This installs a venv, writes a systemd user unit, and starts it.

# Reboot survival needs lingering (`sudo loginctl enable-linger $USER`); we try
|

# it but it's fine if it fails — the service still runs for the current login.
