### Claim evidence

I am the owner and maintainer of the `NicholasHsiang` publisher/namespace.

`NicholasHsiang` is the publisher name I have historically used for my VS Code extensions, while `xianghongai` is my GitHub and Open VSX account.

I maintain and publish multiple VS Code extensions under this publisher. Examples include:

* `NicholasHsiang.vscode-react-snippet` — React Snippets
* `NicholasHsiang.vscode-vue3-snippets` — Vue 3 Snippets
* `NicholasHsiang.vscode-opened-editors` — Opened Editors
* `NicholasHsiang.vscode-explorer-kit` — Explorer Kit
* `NicholasHsiang.vscode-react-ecosystem-snippets` — React Stack Snippets

These extensions and their source repositories are owned and maintained by me under my GitHub account (`xianghongai`).

GitHub account:
https://github.com/xianghongai

Example repository:
https://github.com/xianghongai/vscode-opened-editors

I currently maintain and publish multiple extensions under the `NicholasHsiang` publisher on Open VSX and would like to claim ownership of the corresponding namespace.

Start by searching open-vsx.org for the NicholasHsiang namespace, then verify the publisher at the VS Code Marketplace and inspect the linked GitHub repository's package.json as described. Done means the ownership evidence is confirmed and the namespace claim can be processed.
