Policy type errors prevent configuration enforcement

When system policy values are configured with incorrect data types (e.g., string instead of boolean, or vice versa), the Tailscale client reports an error and the policy fails to take effect. The error appears as '{unexpected key value type}' in syspolicy output.

Run 'tailscale syspolicy list' or 'tailscale syspolicy reload' to identify policies with type errors. Check the Error column for '{unexpected key value type}'. Verify each policy's expected data type in the documentation (boolean, string, or list). Correct the policy value in MDM, Group Policy, or registry to match the expected type, then reload policies.
