Expected Behavior

The \"Save to project memory\" feature should successfully save content to the CLAUDE.md file without path validation errors.

Actual Behavior

The operation fails with a path validation error even when using the correct memory file path.

Environment

• Platform: Linux 6.1.0-37-amd64 (LXC container)
• Claude Code version: 1.0.31
• Running as: root
• Working directory: /claude
• Memory file path: /claude/CLAUDE.md
• Directory permissions: drwxr-xr-x (755) owned by root:root
• File permissions: -rw-r--r-- (644) owned by root:root

Workaround

Direct file editing using Edit/Write tools works correctly, only the built-in memory save feature is affected.

Additional Context

• Running inside LXC container as root user
• The file exists and is writable
• Direct manipulation via Edit tool works without issues
• The error appears to be in the path validation logic of the memory save feature (function MJ5)
• The validation seems to incorrectly reject the correct path
