RuntimeWire reported on October 19 that a comparison of preserved Claude web-client bundles found a new gated organization setting, 'drifting_dusk_cc_enabled', in the October 19 capture that was not present on October 14. The setting sits beside DKIM controls and is wired to an organization-update API.

The name suggests a possible way to CC Claude on email, managed through Anthropic's organization settings. RuntimeWire is careful about the bounds: the client code does not establish a customer rollout, and it does not show that Claude can join or reply to email threads.

How such a feature would relate to Claude's existing Gmail and Outlook connectors is also unknown. Until Anthropic announces anything, this stays a rumor based on reverse engineering of shipped client code, not a product launch.
