The deploy-side double-nest fix lives in the app catalog (templates dropped the extra felhom-data segment). This adds the controller-side invariant test that ties the deploy path (ParseComposeHDDMounts) to the backup path (AppDataDir/NamespaceRoot) so they can't drift again, plus the v0.52.0 CHANGELOG.
