README.md's credential-audit table and command-injection writeup still
described the per-user auth binding gap as open; it's been closed since
2026-07-26. SETUP.md's TSIG section still taught the old single-shared-
key pattern for a fresh install - replaced with the per-host key +
update-policy pattern actually running in production now, plus a
pointer to the phased-rollout approach documented in TODO.md.

Same evasion pattern already fixed for sshd recurred against dovecot: a
coordinated IMAP password spray paced just outside the 30-minute findtime
window ran unbanned for days. Widened dovecot's findtime the same way,
and updated SETUP.md so future provisioning applies this to every
credential jail up front instead of waiting for it to reappear.

Records the host's service inventory, setup runbook, mail account list,
sync plan, package diff vs. clean install, and hardening TODOs, including
today's SSH hardening (key-only, no root login) and the fail2ban sshd
findtime fix for a low-and-slow brute-force evasion pattern.
