codex - 💡(How to fix) Fix Show code review comments in chat as well as the diff UI

Problem

In the current Codex app review flow, code review comments emitted by the assistant as inline review comments are not readable in the chat transcript. The visible chat output can collapse to a short one-line marker, and clicking it opens a side panel where the full comment is expected to appear. In practice, this makes the review hard to use because the actual review content is either not visible in chat or is only discoverable through the diff/comment UI.

This is a regression from the previous behavior where review results were visible directly in the conversation. The chat transcript is the primary place users read the review, compare findings, and understand the reasoning. The diff view is useful for anchoring a comment to a line, but it should not be the only place where the review content is available.

Why this matters

Code review output is not just an annotation. It usually needs context:

• what behavior was reviewed
• why the changed line matters
• what scenario breaks
• what the author should change
• what was verified and what remains unverified

When that content is hidden behind a side panel or only attached to the diff, the review becomes difficult to read as a coherent result. It also makes it harder to refer back to the review later in the same conversation.

Expected behavior

Codex should support seeing review comments in both places:

1. In the chat transcript, as normal readable review feedback.
2. In the diff UI, anchored to the relevant changed line when an inline code comment is available.

At minimum, there should be a setting to choose one of these modes:

• show review comments in chat only
• show review comments in diffs only
• show review comments in both chat and diffs

The safest default for review tasks is probably "both", because the chat gives the full review narrative while the diff gives line-level navigation.

Actual behavior

The chat can show only a short one-line representation of the review comment. Clicking it opens a side panel, but the full comment is not reliably visible there, and even when it is, the chat transcript no longer contains the complete review content.

Suggested fix

Please restore the previous ability to read full review comments directly in the chat transcript, while keeping the new diff/sidebar annotations as an additional navigation aid. If there is concern about duplicate content, make it configurable rather than removing the chat-visible review output.
