721 Filtering by `scope_id` requires the `managed-agents-2026-04-01` beta header on the files request. The SDK files methods send only the files beta automatically, so the examples pass it explicitly.
721 Filtering by `scope_id` requires the `managed-agents-2026-04-01` beta header on the list request, so the SDK and CLI examples make that call through the `beta` namespace and pass the header explicitly. Downloading a file by ID needs no beta header.
