[BUG] Windows image paste (Alt+V) fails in Claude Code but works in Codex CLI on the same terminal/clipboard

Image paste via Alt+V fails on Windows, and I can rule out the terminal, the clipboard format, and keystroke interception via a same-environment cross-tool control.

Environment

• Windows 10 Home (19045)
• Windows Terminal (native Win32 console host — not VS Code/Electron)
• Claude Code v2.1.201 (well past the v2.1.157 WSL/BMP fix, so this is not that already-"fixed" case)

Steps to reproduce

1. Take a screenshot with Win+Shift+S (a standard bitmap is placed on the clipboard).
2. Confirm the clipboard really holds the image by pasting into Paint/Word — it works.
3. In Claude Code (Windows Terminal), press Alt+V.

Result: Claude Code reports "no image in clipboard", although the image is verifiably present.

Key data point — same clipboard, same terminal, different tool:
In the same Windows Terminal, with the same clipboard contents, Codex CLI pastes the image with no problem. This isolates the failure to Claude Code's own Windows clipboard-image read path.

Related, already-closed issues that were never actually fixed: #57316 (closed as duplicate of #4272, which was bot-closed & locked) and #61883 (a failed paste also wipes the clipboard, closed as not planned).

Working workarounds: drag-and-drop, and typing a file path.
