Worked on stabilizing the SSO authentication flow for the supabase/auth-py repository, focusing on backend development and authentication using Python. Addressed a critical bug by relocating the redirect_to parameter from a top-level argument into the gotrue_meta_security metadata, which improved the correctness and security of post-login redirects. This targeted code change aligned client-side and server-side expectations, reducing the risk of incorrect redirects and enhancing the reliability of the authentication process. No new user-facing features were released during this period, as the primary effort centered on refining the existing authentication flow to ensure a smoother and more secure user experience.
