Unclear Nothing has been read yet about the tengu_violin_plan_classifier or tengu_violin_mute gates, so it's unclear what governs this check or its practical effect on using plan mode.
What
A new helper, Ro(), decides whether "plan" is a valid, selectable permission mode and whether the auto-mode/classifier-based permission-check path (used for deciding tool permissions) applies to a given session mode. For plan mode specifically, this now first checks a feature gate, tengu_violin_plan_classifier (enabled by default, evaluated with a tri-state check), before the classifier-based path is allowed to apply.
Why
This lets Claude Code control, and if needed roll back, classifier-based permission checks for plan mode independently of other modes, without requiring a code change.
