# Project Notes - Keep `README.md` current when changing purpose, flows, APIs, scopes, configuration, deployment, or implementation status. - Treat `README.md` as the first project source of truth until a dedicated `docs/` structure exists. - The implementation language is C# / ASP.NET Core. - Member Center remains the OAuth2/OIDC issuer and JWKS provider. This project is the file access boundary for `file_access_api`. - `tenant_id` is part of the File Access boundary model. - Delegated download token issuing and validation live in Member Center; this project must integrate with its validation endpoint rather than becoming a second token issuer.
