Using Clean Architecture with ASP.NET Core 8 | .NET Conf 2023 and this Medium article as references, the "Infrastructure" project/layer (called Integrations in this repo) seems to be appropriate for holding all data access implementations, including repositories, caching, and clients for external APIs,

From this, we are deciding to try placing the clients/repositories in the Integrations project

Refactoring requires regression testing and I put my trust in the automated tests.
