Server-sent Yield setting replaces a teleport menu component

What

Claude Code has a new feature called Yield. It is controlled by a value sent from Anthropic's servers under the name tengu_dazzling_acorn, a remote setting that can change without a new release.

• tengu_dazzling_acorn has no built-in default and starts empty.
• Claude Code checks the value's shape. It uses the setting only when the value's enabled field is true.
• A malformed value logs an error saying the setting "has an invalid value, so this session has no Yield". The session then runs without Yield. A session is one conversation with Claude and its history.
• In the same place in the code, a component that showed the TeleportMenu and resume flow was removed. That component appeared when tengu_teleport_send_to_cloud was set, and its fallback was off.

The findings do not show where tengu_teleport_send_to_cloud is read now, or what calls the new Yield reader. Nothing has been read yet about tengu_dazzling_acorn, so its state is unknown. For tengu_teleport_send_to_cloud, the flag server returned off for this site's account and for the anonymous baseline. No reading of it has been taken under this release.

Why

Yield stays invisible unless the server sends a valid value. The members do not say what it does. The teleport menu is gone from this particular spot. The findings do not say whether the move-to-cloud flow has been removed elsewhere or moved somewhere else.
