The worker isolated HERMES_HOME only. The longrange_backup_pipeline task
("schedule it nightly at 2am") let agents run the operator's real crontab
and write into the real ~/.hermes: a past battery left three nightly cron
jobs and two scripts behind on the host, pointing into deleted run dirs.
sandbox.isolate_host turns on the product's own TERMINAL_HOME_MODE=profile
contract, points the worker's HOME at the same profile home (in-process
~ expansion for write_file), puts a file-backed crontab shim first on PATH
and unsets the systemd user bus. README quickstart drops its /tmp paths.
