AdminOpenAuth clears the admin flag and the ACL roles on every login that no role-assignment rule matched (UserResolver::getUserChangeSet). The Playwright login therefore demoted the provisioned administrator, the admin backend rendered empty, and the next provisioning run answered 403 FRAMEWORK__MISSING_PRIVILEGE_ERROR. The client now carries a rule with userBecomeAdmin, and a separate step re-asserts the flag for accounts an earlier login already demoted, which no console command can do.
discoveryDocumentUrl stays empty because a successful discovery assigns the document over the explicit endpoints and moves the back channel onto the .onion host cURL refuses to resolve.
system:install --basic-setup provisions admin/shopware with a published password; that account is locked on first install. shopware.yaml is mounted again after being rendered but unmounted since the mounts moved into meta/volumes.yml. files/ is split into php/ and shell/ trees.
