Add portainer, uptime-kuma, and homarr on a new 'management' network, with caddy joined to it and internal-only Caddy routes for portainer/uptime/homarr/router. Widen the internal_only allowlist to also accept 172.16.0.0/12 (Docker networks) and 127.0.0.1 so container-originated and local checks pass the LAN gate.
RESUME_AUTH_SECRET and FAMAPP_AUTH_SECRET now replace the bare AUTH_SECRET (previously defined 3x in .env, last-wins). Each is pinned to the value its container is already running, so re-applying recreated nothing. This fixes resume's app reading \\\, which was undefined and resolved to an empty string -- the next container recreate would have wiped all resume sessions. Caddyfile: removed matrix.ginnoir.com and the ginnoir.com apex .well-known/matrix block (no Synapse backend on :8008). Applied to valhalla: dc config resolves with no warnings, Caddy reloaded, dc up -d left every service up-to-date.
Mirror the three production files (docker-compose.yml, .env, Caddyfile) that live on valhalla, plus the push/pull PowerShell scripts, CLAUDE.md, .gitignore/.gitattributes, and .claude/skills for ssh/apply/sync.
