Supported runtime access to effective entity schemas without a personal access token

[lacayoj]

We are preparing a closed test using Base44 backend functions and an Actor. Before performing a bounded write, our adapter needs to validate the effective JSON Schema of two app entities.

The Get entity schema reference uses https://app.base44.com/api/apps/{app_id}/entity-schemas/{entity_name} and requires a personal access token. We do not want to store an editor's personal token in the app or assume the runtime service credential is interchangeable with it.

Is there a supported function/Actor API for reading effective schemas with app-owned runtime credentials? If not, is schema validation through the management API before a bounded execution the recommended approach, and does Base44 expose a schema revision guarantee for that execution?

We are asking for the supported integration pattern, not for permission changes. We have not enabled the write test or changed access rules.
