- app runs as uid 1000; a one-shot data-permissions service chowns ./data to it
and closes it to others (works on an older root-owned install with no host sudo);
files are created 0600 (umask 077)
- python:3.12-slim and caddy:2-alpine pinned by digest; dependencies installed from
requirements.lock with --require-hashes
- the Fernet key is XPRV_ENCRYPTION_KEY_FILE (./secrets/xprv_encryption.key, a compose
secret), out of every environment variable and of a ./data backup
- setup.md no longer presents a second way to run the server (B-72)
