From 0d8db00d7aa40cf741d57460731654c29f034350 Mon Sep 17 00:00:00 2001 From: clagentic <10177887+akuehner@users.noreply.github.com> Date: Wed, 10 Jun 2026 21:06:47 -0400 Subject: [PATCH 1/4] fix(lr-a3ca): replace double getPendingNavigate() with peekPendingNavigate() in history_meta getPendingNavigate() clears pendingNavigate on every call. The history_meta branch called it twice: the first call returned the nav object and nulled it; the second returned null and threw TypeError on .toolId access. The nav was also consumed before history_done could use it, so the "Go to chat" scroll never fired. Add peekPendingNavigate() to filebrowser.js that reads pendingNavigate without clearing it. Replace the triple getPendingNavigate() calls in the history_meta condition with a single peekPendingNavigate() into a local. The consuming getPendingNavigate() in history_done is unchanged and remains the sole consumer.
