[BUG] Cowork: Scheduled reserved-path overlap blocks mounting ~/Documents/Claude and every parent folder — no scheduled tasks ever created

What's Wrong?

What's wrong:
Cowork refuses to mount ~/Documents/Claude with the error:

Directory "/Users/[user]/Documents/Claude" overlaps a protected host location (/Users/[user]/Documents/Claude/Scheduled) and cannot be mounted. Request a project or document folder instead.

The reserved Scheduled folder does not exist on disk (ls confirms no such file or directory), and I have never used the scheduling feature or created any scheduled task. The mount validation appears to compute a reserved Scheduled path under whatever folder is selected and reject the parent for overlapping it.

Key detail — the error follows the selected folder:

Selecting ~/Documents/Claude → error names .../Claude/Scheduled
After moving all content into a new subfolder and selecting ~/Documents/Claude/Workspace → error names .../Claude/Workspace/Scheduled
So no folder containing my context can be mounted. Only a leaf project folder (e.g. .../Claude/smartwithit) mounts — but that excludes the top-level CLAUDE.md and shared skill folders that Cowork needs for context, making it unusable for my workflow.

Timeline: Worked fine for weeks. Broke immediately after quitting and restarting the app. No file changes were made on my end. App reports it is up to date (no update available).

Ruled out:

Documents folder permission is granted (Privacy & Security → Files & Folders → Claude → Documents Folder = on)
No quarantine flags remain (cleared with xattr -dr)
No scheduled tasks have ever been created
~/Documents/Claude/.claude/launch.json has empty configurations; settings.local.json contains no workspace path or Scheduled reference
Scheduled folder does not physically exist anywhere under ~/Documents/Claude
Environment:

macOS Sequoia 15.6 (24G84)
Claude Desktop 1.15200.0
Cowork
Expected: Cowork should mount ~/Documents/Claude as before. The reserved Scheduled path should not block mounting a parent folder when no scheduled tasks exist / the folder is absent — or the reserved-task storage location should be configurable / moved out of the mounted tree (cf. issue #54859).

What Should Happen?

Cowork should have access to my designated Claude folder contents.

Error Messages/Logs

The full workspace can't be mounted due to a protected subfolder.

Steps to Reproduce

Start a cowork session. It tries to read claude.md and follow other instructions requiring access to files in my Claude folder and it stops and gives the error message.
