Two root causes behind the blank F6 run: 1. project.godot had no display/stretch config (README mandates canvas_items @ 1920x1080). Added [display] window size + stretch mode/aspect — the project's canvas foundation, needed by every screen. 2. A root Control run directly (F6) is not sized to the viewport by full-rect anchors — it collapses to (0,0), clipping the ScrollContainer and hiding all content. Size the root to the viewport explicitly and track size_changed (dropping the full-rect anchors, which conflict with setting size directly). Faithful main-scene run now measures root = scroll = viewport = 1920x1080. Suite 125/125. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
