Description: Follow-up to #2925. That PR added url_preserve_empty_path=True to OAuthClientMetadata, which also changes the serialized form of redirect_uris on the wire — a path-less redirect URI passed as a string now drops its trailing slash, and the client sends it verbatim in /authorize and token-exchange requests. Since RFC 6749 §3.1.2.3 mandates exact string comparison of redirect URIs at the authorization server, a registration persisted in TokenStorage before the upgrade could stop matching. This extends the existing migration note to call that out and tell affected users to re-register. Spotted by the Claude review bot on #2925: #2925 (comment) AI Disclaimer This PR was developed with the assistance of either Claude or Codex. I've reviewed and verified the changes.
