New internal flags added, including bashActFirstEnabled and three codename gates amber_astrolabe, bison_cairn, larch_cistern
Claude Code adds several new internal flags:
bashActFirstEnabled, controlled by the experimenttengu_gorse_plover(or theCLAUDE_CODE_GORSE_PLOVERenvironment variable)- three codename-style flags,
amber_astrolabe,bison_cairn, andlarch_cistern, each backed by its own experiment and a matchingCLAUDE_CODE_*environment variable override
Several places in the code that used to read the bison_cairn, larch_cistern, and amber_astrolabe flags directly were rewritten to instead read fields off local event objects, such as pollEmptyDispatch and ideSelection.
These are internal flags for gradually rolling out unreleased behavior, so nothing changes for most users yet. The shift away from reading the flags directly at some call sites suggests those particular checks are being replaced by more targeted logic.
tengu_gorse_plover Off in both readingsThe flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

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.
