Restore the Exobrain harness onto a wiped Mac or a brand-new machine, from the daily collective backup tarball + GitHub + cloud re-auth. Use when Alex says "restore the harness", "restore from backup", "set up the harness on this machine", "new Mac setup", "rebuild the machine", "disaster recovery", or is bringing a fresh/wiped Mac back online. NOT for the Mac Mini server split (that is MAC-MINI-MIGRATION-PLAN.md, which assumes the old machine is still alive).
