- SHARED_SECRET now read from env and fail-closed: unset/placeholder refuses
ALL plugin connections (constant-time compare). The old hardcoded
'your_shared_secret' in this public repo was no auth at all. Dockerfile
default removed; generate_data.py reads the env var.
- SECRET_KEY fails closed at startup (main.py and agent/auth.py) instead of
falling back to a publicly-known signing key; agent systemd unit now
requires /etc/overlord/agent.env (no '-' prefix).
- AuthMiddleware + /ws/live: replace the 172.x source-IP trust (which every
nginx-proxied internet request satisfied via docker-proxy — full session
bypass and unauthenticated in-game command injection) with
private-source AND no X-Forwarded-For, i.e. only genuinely internal
callers (overlord-agent on the host, compose-network services). Invariant
documented in nginx/overlord.conf: every tracker-bound location must set
X-Forwarded-For.
- /character-stats/test endpoints gated behind admin (they upsert real rows).
- docker-compose: bind 5432/5433 to 127.0.0.1 (both DBs were internet-
reachable; active brute-force observed in dereth-db logs).
- discord-rare-monitor: drop dead SHARED_SECRET constant.
- scripts/backup-databases.sh + docs/backups.md: nightly pg_dump of both DBs
(telemetry/spawn hypertable data excluded), 10MB canary, umask 077,
TimescaleDB restore procedure.
- Remove stray mangled-path css file from repo root.
Adversarially reviewed pre-deploy (3-lens workflow): ship verdict; deploy-
sequencing blockers addressed (secret staged before enforcement, exec bit
set, cron uses bash).
