I am sorry, but I was unable to retrieve the content of the README file for the haydenbleasel/files-sdk repository using the available tools. I attempted to access the raw file content from both the main and master branches, as well as the main repository page, but all attempts resulted in an error.

To proceed, please provide the content of the README file directly, or ensure that the repository and its files are accessible via the provided URLs. Once I have the content, I can generate the technical due-diligence brief.
