This connects the proxy socket from your host into the container so Pulse can communicate with it.
> **Security Note:** The socket mount is read-only (`:ro`) to prevent compromised containers from tampering with the socket directory. The proxy enforces access control via SO_PEERCRED, so write access is not needed.

`allowed_peers` lets you scope access: grant the container UID only `read` to limit it to temperature fetching, while host-side automation can receive `[read, write, admin]`. Legacy `allowed_peer_uids`/`gids` remain for backward compatibility and imply full capabilities.
**Environment Variable Overrides:**
Config values can also be set via environment variables (useful for containerized proxy deployments):
