What probably matters to youSection of the release
What
The per-session experiment-memoization system gained a new field, bashFirstSteerVariant, joining existing experiment slots like preReadLineDropped, leanPrompt, modelForPrompt, and delegationCostsFirst. It defaults to "strict" and can be controlled by the tengu_cozy_teapot gate or overridden with the CLAUDE_CODE_COZY_TEAPOT environment variable.
Why
This is infrastructure for testing variants of the 'bash-first' steering wording that pushes Claude toward using Bash for edits, allowing the behavior to be adjusted per session without a code change.
Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

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.
