- deploy/docker-compose.yml: pinned-tag ghcr image, hardened (cap_drop ALL + minimal cap_add, no-new-privileges, panel bound to 127.0.0.1 only). Apache itself runs on the host (spec 10.5), fragment at deploy/apache/. - Alternative reverse-proxy fragments: nginx (+certbot sidecar), Caddy (automatic ACME), Traefik (+acme.json PEM extraction script). - .github/workflows/release.yml: tag-triggered ghcr.io publish, version piped from the git tag into both the binary ldflags and the image tag (spec 10.1). - Closed a gap from Phase 1: logrotate was installed but never invoked; wired up build/logrotate-mail.conf + logrotate-loop.sh + a supervisor program (copytruncate, since postlogd holds mail.log open with nothing to signal on rotation). - README rewritten: site requirements checklist, reverse-proxy comparison, DNS setup (server- vs domain-level), IP warmup, backup/restore vs domain export/import, fixed-tag rationale, machine requirements.
