Worked on the openid/OpenID4VCI repository to enhance credential issuance workflows by improving the flexibility of Credential Issuer Metadata. Focused on clarifying the optional use of the 'scope' parameter and enabling 'authorization_details' as an alternative for requesting credentials when supported by Authorization Server metadata. This approach reduced ambiguity and improved interoperability across diverse Authorization Server implementations, supporting broader client adoption and minimizing issuance failures. The work was delivered through a targeted commit and documented using Markdown, with an emphasis on clear, maintainable documentation and adherence to OpenID Connect standards. No major bugs were addressed, reflecting a focus on feature clarity.
