 ## Conclusion
 
-ADR-019 has been successfully implemented. The IndieAuth authentication flow now correctly implements PKCE as required by IndieLogin.com, uses the correct API endpoints, and validates the issuer. Unnecessary features from v0.7.0 and v0.7.1 have been removed, resulting in cleaner, more maintainable code.
+ADR-025 has been successfully implemented. The IndieAuth authentication flow now correctly implements PKCE as required by IndieLogin.com, uses the correct API endpoints, and validates the issuer. Unnecessary features from v0.7.0 and v0.7.1 have been removed, resulting in cleaner, more maintainable code.
 
 The implementation follows the architect's specifications exactly and maintains the project's minimal code philosophy. Version 0.8.0 is ready for testing and deployment.
