Since Feature 18 the integration is a client of the NestQuest API
service and the admin surface is the PWA plus the API's admin routes,
so the integration must not keep HA services for admin operations.
Drop every admin service handler and its registration (uncomplete,
create/update/set-active quest definition, presence pattern and
overrides, CSV export, manage_child, regenerate) together with the
Feature 09 permission gate that existed only for them: permissions.py,
service_policy.py and the core SERVICE_POLICY registry, the
regenerate handler plumbing in __init__, the dead payload schemas and
services.yaml entries, and the service-name constants they alone
used. Only the panel completion path (nestquest.complete_quest)
remains, still proxying to the entry's shared API client. The four
automation blueprints are untouched — they only read sensors and
listen to bus events.
Parametrised test denies no-context calls on every admin-only service;
complete_quest proceeds with no user; scheduled internals stay direct
function calls.
permission_gate wraps all registered services at registration time:
admin-only policy reads call.context.user_id against admin_allowlist
is_admin (fail closed on no context); complete_quest stays open.
