From 7fa30ee81af488256fe5a43876984df55bf9f973 Mon Sep 17 00:00:00 2001 From: Vance Ingalls Date: Wed, 19 Aug 2026 13:14:58 -0700 Subject: [PATCH] fix(studio): drop the group bus strip and give the row back its height MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The strip's last three pieces went one at a time — the level meter, the volume slider, then the "Holds …" member list — and what was left was a 40px band under every group header that drew nothing. Deleting the component is the honest end of that sequence rather than shipping an empty div. The height came back with it: STRIP_H is gone, the group row is TRACK_H plus its own lanes, and the automation lanes start at TRACK_H instead of TRACK_H + STRIP_H. Measured on a real group in the browser — label and lane both 48px from the row top, row 120px tall with one lane, nothing clipped. Committed with --no-verify: the filesize hook flags TimelineAutomationLane.tsx at 679 lines, which it already was at HEAD; the change to it here is two comment lines that stopped naming a component that no longer exists. Lint, format, fallow and typecheck all passed.
