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.

No source file, entry point, or test is named. Start by locating the Codex desktop rendering path for local file citations and reproduce the DOCX case from the listed steps. Done means the DOCX filename is visible and the attachment is clickable or downloadable, while the following Markdown link still renders normally.
