  • The GitHub account is read by hand from the first attached screenshot, a profile page headed Code Maestro with the handle codemaestro11, 56 repositories, and a README whose language breakdown is mostly TypeScript and Solidity. The post's own text states the two names and adds that the operator may attach the number 917 to email addresses; no address is shown, so none is recorded here. This is one of the names docs/x-source-backlog.md had been carrying as unresolved on the belief that it existed only inside an image. It is in the post's text, in a window the sweep never reached.
