/ide picker shows duplicate entries per PhpStorm window in WSL2 setup, defeating auto-connect

Summary

When running Claude Code CLI in WSL2 with PhpStorm running on the Windows host, the /ide picker shows two identical entries for each PhpStorm window. Because there are two entries instead of one unique match, auto-connect cannot fire and /ide selection is required every session.

Environment

• Claude Code: v2.1.119 (native install, WSL2 Ubuntu)
• WSL2: Ubuntu 24.04 with networkingMode=mirrored
• Host OS: Windows 11
• IDE: PhpStorm with Claude Code [Beta] plugin (https://plugins.jetbrains.com/plugin/27310-claude-code-beta-) installed
• Multiple PhpStorm windows open (one per project)

Reproduction

1. Have multiple PhpStorm windows open on Windows, each with a distinct project under WSL home (e.g., /home/user/web/<project>)
2. From PhpStorm's integrated terminal OR from a standalone Windows Terminal/PowerShell with no JetBrains parent, run claude in WSL
3. Run /ide

Expected

Each running PhpStorm window should appear as exactly one entry in the picker. With one cwd-matching entry, auto-connect should fire (per docs) without prompting.

Actual

Each PhpStorm window appears TWICE in the picker. The cwd-matching project shows two identical entries, preventing auto-connect from identifying a unique match.

Investigation

Lock files on Windows side (C:\Users\<user>\.claude\ide\*.lock) show one file per PhpStorm window — no duplicates at the filesystem level:

\\\
51712.lock → workspaceFolders: [\"/home/dtocci/web/omni-api\"]
54802.lock → workspaceFolders: [\"/home/dtocci/web/intranet\"]
55559.lock → workspaceFolders: [\"/home/dtocci/web/website\"]
63678.lock → workspaceFolders: [\"/home/dtocci/web/my.omni\"]
\\\

WSL-side ~/.claude/ide/ does not exist.

Tested with and without JetBrains JediTerm env vars (\CLAUDE_CODE_SSE_PORT\, \TERMINAL_EMULATOR=JetBrains-JediTerm\). Duplicates persist in both cases — so the second entry is not from env-var discovery overlapping lock-file discovery.

• #14421 — IDE lock file deleted in WSL (related WSL-side bug)

Impact

Auto-connect, the most natural UX for \/ide\, is broken for the entire WSL2 + Windows IDE class of users. Manual \/ide\ selection is required every session.
