Anonymous. No account, no email.
What
When Claude Code emits the JSON schema for settings and the policy helper, any property whose description is marked internal is deleted outright and removed from the required list. A second emission mode keeps the property and just strips the marker from its description.
Evidence
@internal
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
