Claude Code /config diagnostics reports "native install not in PATH" even when it is (Windows)

Bug

/config diagnostics panel shows:

⚠ Native installation exists but C:\Users\M44041\.local\bin is not in your PATH

Even though the path IS present in both the Windows User PATH and the current process PATH.

Environment

• Claude Code version: 2.1.112
• OS: Windows 11 Enterprise 10.0.26100
• Shell: PowerShell

Details

• C:\Users\M44041\.local\bin\claude.exe exists
• C:\Users\M44041\.local\bin is in the Windows User PATH (verified via [Environment]::GetEnvironmentVariable('Path', 'User'))
• The path is also in the process PATH (verified via $env:Path in PowerShell)
• DISABLE_INSTALLATION_CHECKS=1 is set — this suppresses the startup warning but NOT the /config diagnostics panel

Expected behavior

/config should not show the PATH warning when the path is present. Alternatively, DISABLE_INSTALLATION_CHECKS=1 should also suppress the /config diagnostic.

Likely cause

The diagnostics check may be doing a case-sensitive or format-sensitive path comparison that fails even when the binary resolves correctly on Windows.
