[BUG]

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

A Matt Pocock repository I have collaborator/org access to (not one I personally own) doesn't appear in the Claude Code mobile app's repository picker, even though Claude Code works fine with this same repo on desktop and has been updating it for months. The Claude GitHub App is confirmed installed and working — this is mobile-specific.

### What Should Happen?

Matt Pocock Repo should appear in the mobile picker since Claude already has working access to it via desktop.

### Error Messages/Logs

```shell

```

### Steps to Reproduce

Open Claude mobile app → Code tab → new session → repository selector
• Search/scroll for [repo name] — does not appear
• Same repo works normally in Claude Code on desktop

### Claude Model

Not sure / Multiple models

### Is this a regression?

Yes, this worked in a previous version

### Last Working Version

_No response_

### Claude Code Version

N/a can’t access repository

### Platform

Anthropic API

### Operating System

macOS

### Terminal/Shell

Other

### Additional Information

Already tried: logging out and back into the mobile app — did not resolve it. Suspect this is the known backend repo-indexing issue also reported in #34523, #61019, and #65601.

Start by reviewing the related repo-indexing reports #34523, #61019, and #65601, then compare the mobile Code tab repository selector with the desktop behavior described here. Reproduce with a collaborator-owned repository where the GitHub App is installed; done means the repository appears in the mobile picker without requiring reauthentication.
