codex - 💡(How to fix) Fix review panel large-diff mode should still allow choosing which file to inspect

What issue are you seeing?

when a changeset has many files changed, the review panel enters a “large diff detected — showing one file at a time” mode.

the problem is that the ui appears to force review in its own file order. there is no visible way to choose which file’s diff to load next from the changed-file list. in my case i had ~69 files changed after a large refactor, and the review panel only showed one file (README.md) instead of letting me pick the specific files i actually wanted to inspect.

why this matters: large refactors often have many mechanical files plus a few high-risk files. reviewers need to jump directly to the important files first. limiting rendering is fine; limiting navigation is the bad part.

What is the expected behavior?

expected behavior:

• large-diff mode may render only one file at a time
• but the review panel should still show a selectable file list / file picker
• clicking a file should load that file’s diff

actual behavior:

• large-diff mode shows one file at a time
• the user is effectively forced through files in the app’s chosen order
• this makes targeted review of large refactors unnecessarily painful
