### Claim evidence

The namespace matches the GitHub ID making this request

Namespace: joshua-barbosa
Extension: joshua-barbosa.braytech-code

Evidence:
The namespace name is my GitHub username, which is also the account I use to
log in to open-vsx.org.

The extension is published from this public repository, owned by that same
GitHub account:
https://github.com/joshua-barbosa/dev-ide

Commit that sets the publisher field to this namespace, in
extensao/package.json:
https://github.com/joshua-barbosa/dev-ide/commit/f6ddd5172eb702ff6bd5b9cde850d0eb00ba87c0

I am the sole author of the extension and of the repository.

Verify that the joshua-barbosa namespace is unowned on open-vsx.org and that the listed VS Code Marketplace conditions match the checked boxes. Review the linked dev-ide repository, extensao/package.json, and referenced publisher commit; done means the ownership evidence and namespace claim satisfy the applicable process.
