Unclear Nothing has been read about the tengu_swift_lynx gate, so whether or how it is switched on for any account is unknown.
What
New per-session/global state fields, promoStartupConfig, promoStartupConfigParse, promoStartupLoginsSeen, and promoStartupLoginEnded, along with an announcementSlotReleased flag, track a startup promotional announcement and end it once a tracked number of logins has occurred. These fields back a new hidden local command that opens the page for the offer shown at startup. The command only activates when a remote-config value under the tengu_swift_lynx gate is non-null.
Why
This lets Claude Code show a startup promotional offer for a limited number of logins and gives users a way to revisit that offer's page, while keeping the feature off unless explicitly configured remotely.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
