Gandi LiveDNS rejects the RFC-7505 null-MX value '0 .' ('invalid format for MX
record'), which failed the live apply. No MX + no apex A = no mail delivery, and
SPF -all + DMARC reject still prevent spoofing — so remove Gandi's seeded MX (add
@/MX to absent) rather than declare a null-MX present. Assert now requires an SPF
@/TXT record; tests + Molecule sample updated.

Local Ansible roles. No Galaxy roles — every role is written and maintained here
(ADR-003). Scaffold new ones with make new-role NAME=<name>; never create the
directory structure by hand.
Each role must have: a molecule/default/ scenario (Debian 13), a populated
README.md, and a filled-in meta/main.yml. Conventions: CLAUDE.md and
docs/runbooks/new-role.md.
Current state: base is partially built — its firewall concern (nftables) is
implemented and tested; the other concerns (SSH hardening, fail2ban, auditd, packages,
users) are not yet built. docker_host is scaffolded but has no tasks yet. dev_env (interactive
developer environment) is built and applied. See STATUS.md for the authoritative
breakdown.
