Hi maintainers,
I’d like to work on this issue. I have solid backend experience implementing sandbox and mock provider modes to enable local development and reliable testing.

I’ve built systems that support adapter abstractions with real vs mock implementations, ensuring mock responses closely mirror production behavior. I’ll make sure the sandbox mode is easy to use for contributors and properly covered by unit tests.

Please let me know if there are any conventions or constraints I should be aware of before starting.
