47-48: Optional: In-line documentation could clarify fallback behavior.Consider adding a short comment about why the fallback is necessary and under what circumstances a custom checker might be provided.
62-62: Clarify error messaging for more user-friendly guidance.The error hint is concise, but consider adding a note on how to configure or register a confidential client for http usage. This might help developers troubleshoot quickly.

43-45: Rename method appears consistent with best practices.
Renaming secureChecker to GetRedirectSecureChecker clarifies the method’s purpose. The fallback logic using oauth2.IsRedirectURISecure is a clean way to ensure a default checker is in place.
59-61: Ensure thorough testing for insecure protocols.
This check properly enforces HTTPS for public clients but allows HTTP for confidential clients. Confirm that edge cases like IP addresses or localhost usage are correctly handled, as local dev environments sometimes rely on http://127.0.0.1.
Would you like additional test coverage to validate IP-based redirect URIs or other local development usage?

69-75: Test scenario captures the intended error for public client over HTTP.
This negative test effectively verifies that a public client's HTTP redirect is disallowed. The coverage is appropriate and ensures the error is properly raised.
99-128: Thorough validation of HTTP-based redirect for confidential clients.
The test covers:
- Successful issuance of authorization code.
- Properly captured granted scopes and state.
It's a good addition ensuring HTTP usage is valid for confidential clients.
This allows confidential clients to use the http scheme for a redirect URI.
