The app is the only process on this box accepting unauthenticated input from the internet and it was running as root in a writable container. Now uid 10001, read_only with a tmpfs /tmp, cap_drop ALL and no-new-privileges. Host-side /srv/scout-website/data and the service account key are chowned to 10001. Verified on a throwaway container: every route, the admin API, spam rejection, and a real submission writing to both the jsonl and SQLite.
