What's Wrong?

RPC error: failed to mount ...Documents/Claude/Scheduled/rev-rec-triage-daily...
mkdir .../Users/Fraser.Wilsher/Documents: file exists

Mention: ~/Documents is a symlink → /Users/Fraser.Wilsher/Library/CloudStorage/OneDrive-NiCELtd(2)/Documents. Request: CoWork should call realpath() on task paths before passing them to virtiofs.

Root cause: CoWork discovers tasks via ~/Documents/Claude/Scheduled/ (the symlink path) and passes that path directly to virtiofs for mounting. When virtiofs tries to build the mount, it hits mkdir .../Users/Fraser.Wilsher/Documents and fails because Documents is a symlink, not a real directory. If CoWork used realpath() first, it would use /Users/Fraser.Wilsher/Library/CloudStorage/OneDrive-NiCELtd(2)/Documents/Claude/Scheduled/rev-rec-triage-daily — and virtiofs would succeed.

~/Documents is a symlink → /Users/Fraser.Wilsher/Library/CloudStorage/OneDrive-NiCELtd(2)/Documents
Full error: mkdir /mnt/.virtiofs-root/shared/Users/Fraser.Wilsher/Documents: file exists
Fix needed: CoWork should call realpath() on task paths before passing to virtiofs

What Should Happen?

Claude Cowork should function
