What's Wrong?

In the Rewind overlay, user prompts that include an image attachment are displayed as (no prompt) instead of the prompt's text. Text-only prompts render correctly.

<img width="1004" height="716" alt="Image" src="https://github.com/user-attachments/assets/710df1b9-c88c-4583-8829-2c8db21d147e" />

Environment

• Claude Code v2.1.117
• Model: Opus 4.7 (1M context), high effort
• Platform: macOS (Darwin 25.4.0)

The rewind list renders:

• hello sir — No code changes
• (no prompt) — No code changes ← this row corresponds to the image-bearing turn
• nice — No code changes
• › (current)

The image-bearing prompt's text is dropped and replaced with the (no prompt) placeholder, making it hard (in longer conversations with multiple image-bearing turns) to identify which turn to rewind to.

What Should Happen?

The rewind entry should show the prompt's text along with the usual [Image #] tag.

Steps to Reproduce

1. Start a new Claude Code session.
2. Send a text-only prompt (e.g. hello sir).
3. Send a prompt that includes an image attachment plus text (e.g. paste a screenshot with the caption what does this screenshot say).
4. Send another text-only prompt (e.g. nice).
5. Open the Rewind overlay.

Is this a regression?
