# Hardening
# StateDirectory is created automatically (with correct ownership) before
# the service starts and is writable under ProtectSystem=strict without a
# ReadWritePaths= entry - systemd exposes its absolute path via
# $STATE_DIRECTORY, which config.py picks up for persist_raw_json_dir.
# Unlike ReadWritePaths=, this does not require the directory to already
# exist on disk.
