Codex app renders generated DOCX file citation as an empty list item

Summary

A generated .docx file was present on disk and valid, but the Codex desktop response rendered its file attachment/citation as an empty bullet. A Markdown file link in the next bullet rendered correctly.

Steps to reproduce

1. Ask Codex to create a DOCX document.
2. Have the final response include the generated DOCX as a local file output/citation inside a Markdown list.
3. Open the completed response in the Codex desktop app.

Actual result

The DOCX item appears as a blank bullet with no filename or clickable attachment. The following Markdown link renders normally.

Expected result

The DOCX filename should be visible and clickable/downloadable.

Additional details

• The DOCX existed at the cited absolute path.
• The file passed ZIP integrity validation and rendered correctly to three pages.
• Reproduced on macOS 26.6 (25G72) on 2026-08-10.
• The affected task ran for 10m 42s, and the user then had to spend another turn requesting the file again.
• Screenshot is available from the reporter if needed.
