STUB — page map only. This page exists so the sidebar and the shape of the site are judgeable; M6 writes it.

Must carry: aos status and aos doctor first; journalctl -u aos; a config error refuses the start, so read the journal rather than guessing; the port moved and where it is written down; nothing answers on 7700 (firewall, cloud security group); an Agent says it cannot write somewhere — protected paths and how to unprotect one.
