What issue are you seeing?

I have a Corporate Marketplace of Plugins (hosted on GitHub or a File System mirror), and I have successfully installed a couple of plugins. My plugins have metadata that says: "Developer: Olmstead". This in turn creates a "By Olmstead" tab/button on the Plugins page, but it stopped working -- it shows nothing. Instead, my Olmstead plugins appear on the Personal tab.

My plugins have the Developer metadata:
<img width="339" height="205" alt="Image" src="https://github.com/user-attachments/assets/51b6dd57-b0cf-4cfa-a9e0-9463d83270d6" />

What steps can reproduce the bug?

Install a Plugin that specifies the interface.developerName in its .codex-plugin/plugin.json file:

{
  "name": "enterprise",
  "version": "...",
  "description": "...",
  "skills": "./skills/",
  "interface": {
    "displayName": "...",
    "shortDescription": "...",
    "developerName": "Olmstead",
    "category": "Productivity",
    "capabilities": ["Interactive", "Read"],
    "websiteURL": "...",
    "logo": "./assets/icon.svg"
  }
}

This will create the By Olmstead tab:
<img width="286" height="45" alt="Image" src="https://github.com/user-attachments/assets/ecdbe14c-05a0-45d7-9af6-048875e1f33e" />
But your plugin won't appear there like you'd expect.
It is instead listed on the Personal tab.

What is the expected behavior?

I expect to see the Plugins where Developer is Olmstead to appear under the By Olmstead tab.

Additional information

This used to work, but stopped after the recent redesign of the Plugin user interface -- within the past couple of weeks, I think.

I see this problem on both MacOS and Windows.
