The top is for someone who wants Omarchy: where to get the ISO and how
to check it, how to try a VM image, and autoinstall. Everything about
building, testing and publishing follows under "For maintainers", with
what is published where, how the nightly works, the fields of
latest.json and the files of a VM image.
A read against the code corrected several statements, some of them
older: the installer runs omarchy-provision-user; a defer-provisioning
marker can stand in for the credentials file; an authorized_keys file
fails the install when it holds no keys, not when its keys are bad; the
stock firewall also allows Docker's DNS; built_at is when latest.json
was written; vm-boot's needs are listed in full.
The publish job now fetches the two checksum files back as well, so
"every file of the version is compared" is exact.
