-> The `web_log` suggestion branches on `hostname` in the Code node:
-> - **`majorlab`** → Check `docker logs caddy` (Caddy reverse proxy)
-> - **`teelia`, `majorlinux`, `dca`** → Check Apache logs + Fail2ban jail status
-> - **other** → Generic web server log guidance

 ## Notes
 
-- ~~Port 2222 on **MajorRig** previously existed as a hard bypass for Tailscale SSH browser auth. This workaround was retired on 2026-03-25 after the Tailscale SSH authentication issue was resolved. The entire fleet now uses port 22 uniformly.~~
+- Port 2222 on **MajorRig** exists as a hard bypass for Tailscale SSH browser auth — regular SSH over Tailscale network, bypassing Tailscale SSH entirely. This is an alternative approach if `check` mode is required for compliance but browser auth is too disruptive.
 - The `autogroup:self` destination means the rule applies when connecting from your own devices to your own devices — appropriate for a personal homelab fleet.
