- Force-push or rewrite already-pushed history on `main`
- Add a collection to `requirements.yml` without a specific module need in existing role tasks
- Open a firewall port anywhere but the `group_vars` firewall definitions — never ad-hoc on a host (ADR-002)
- Open a firewall port anywhere but the `group_vars` service catalog — never ad-hoc on a host. If it's not in the catalog, it doesn't exist (ADR-002, ADR-020)
- Disable or weaken a baseline control from ADR-002 (SSH hardening, nftables default-deny, fail2ban, auditd)
- Expose a service to the LAN/WAN without it sitting behind the reverse proxy with authentication (ADR-002)
- Deploy a service that hasn't cleared `docs/security/service-checklist.md` (record any deviation in `docs/security/accepted-risks.md`)
