tengu_still_kestrel falls back to false.

What

A new option decides whether stored credentials are kept when the token they belong to changes. It is controlled by the server-side gate tengu_still_kestrel, and with no server value the compiled fallback is false, so credentials are not kept in this build.

Details
  • The result is computed once and cached on the config object as keepAcrossTokenChanges.
  • If the gate reader returns nothing at all, the helper also returns false.

tengu_still_kestrel Gate removed from the code

This release deleted the gate from the code while it was still reading on for the account this site reads, so the code path no longer asks a flag before running.

What has happened since
Flag reading moved The flag server now returns on for tengu_still_kestrel, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
