post_update._install_root, boot_bootstrap.default_project_root, update_channel._default_root, version_info._CODE_ROOT + _resolve_stamp_file, _launchers.publish_launchers and pm.runtime each re-derived "HERMES_INSTALL_ROOT or the code root". pm.paths.install_root() is the one place now; pm.store reuses the downloader's User-Agent instead of carrying a second one.
