Desktop app (Windows 1.52386.6): SendUserFile card opens a preview drawer with no save/download control, even with display: attach

Summary

In the Claude desktop app on Windows (Code tab), a file card sent from a session with SendUserFile no longer offers a download. Clicking the card opens a preview drawer, and the drawer has no save control either, so there is no way to save the file to a folder of my choosing. Until recently, clicking the card's icon opened a normal Windows save dialog.

The files are plugin .zip archives, which the drawer cannot preview anyway, so the card is a dead end for the exact file type it is meant to deliver.

Environment

• Claude desktop app for Windows: 1.52386.6 (from AppData\Local\Claude\Logs\main.log)
• Claude Code (bundled): 2.1.274 (recorded in the session transcript)
• Windows 11 Home 10.0.26200
• Files: two .zip archives, 15 KB and 268 KB

Steps to reproduce

1. In a Code tab session, have Claude send a .zip with SendUserFile (display: "attach", and also with display unset; both tried).
2. Click the file card in the conversation.

Expected

A download / save-as dialog, as before, so the user chooses where the file lands.

Actual

A preview drawer opens beside the conversation. It shows nothing useful for a zip and has no download or save-to button. Right-click offers nothing. The same happens for display: "attach", which the tools reference documents as "a download card only".

Notes

• Same defect as #86337 (Windows: cards open the file instead of offering a download). Reporting separately with the current version numbers, and to record that display: "attach" and the drawer both lack a save control.
• Workarounds tried from the session side, none of which work: publishing the zip through the Artifact tool (refuses .zip), opening a local download page in the built-in browser pane (file:// is blocked, about:blank#blocked).
• The only remaining route is to have the session write the file to a folder on disk, which defeats the point of a download card and is not something I want a session doing on its own.

Please restore the save dialog on the card (or add a Save button to the drawer), and document how a user is meant to save a delivered file.
