Policy, approvals and errors

SDK function policy ID: google.calendar_calendars_insert. Catalog operation: calendar.calendars.insert. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.

Required provider scopes: ["https://www.googleapis.com/auth/calendar", "https://www.googleapis.com/auth/calendar.app.created", "https://www.googleapis.com/auth/calendar.calendars"]
