### Claim evidence

Provide the requested information (commit URL or domain/subdomain) or a justification for granting ownership of the namespace.

Namespace name 'iyulab' is too similar to existing namespace(s): JyuLab.

`iyulab` has been our organization's publisher identity on the VS Code Marketplace
since March 2024, with six extensions:
https://marketplace.visualstudio.com/publishers/iyulab

Their repositories are owned by the identically named GitHub organization, e.g.
https://github.com/iyulab/vs-tools for `iyulab.copy-text-selected-files`.
The requesting GitHub ID `birdnamoo` is a member of that organization.

We are adding an Open VSX listing at a user's request and need the identical
publisher ID so both registries list the same extension. The blocking namespace
`JyuLab` has no published extensions; we have no affiliation with it.

Start by checking the iyulab publisher page on the VS Code Marketplace, the linked GitHub repositories, and the existing JyuLab namespace on open-vsx.org. Done means the ownership evidence is verified and the iyulab namespace can be claimed for the organization's extensions.
