### Claim evidence

Claiming ownership of namespace `yychuiyan`.

- Open VSX: https://open-vsx.org/extension/yychuiyan/dsh-for-web
- VS Code Marketplace publisher: https://marketplace.visualstudio.com/publishers/yychuiyan
- Marketplace extension: https://marketplace.visualstudio.com/items?itemName=yychuiyan.dsh-for-web
- Public repo owned by this GitHub ID: https://github.com/yychuiyan/deepseek-harness-vscode
- package.json repository field: https://github.com/yychuiyan/deepseek-harness-vscode.git

I have logged in to https://open-vsx.org and published yychuiyan.dsh-for-web v1.0.3.

Check the Open VSX namespace link and the VS Code Marketplace publisher and extension links in the issue, then verify the package.json repository field and the linked public repository. Done means the ownership evidence is valid and the yychuiyan namespace can be claimed for the published extension.
