Unclear What the feature switch controls is not shown.

What

Claude Code now checks a feature switch that Anthropic controls from its servers. It is off unless it is switched on remotely. Claude Code's list of diagnostic items also gains one named auth_session_owner_ask. Neither does anything you can see yet.

Why

This marks a feature that is in the build but not yet turned on or described.
