Section 0 (prologue) has no chapter rows server-side — the prologue is hardcoded client-side in Wizard/Prologue.cs — so the chapter-completion rollup always emitted is_finished=false. The client uses that flag to derive IsTutorialReplay; with it false, AreaSelectUI.OnTouchChapterListTutorial blocks every chapter switch and the default focus (last visible chapter) becomes the only confirmable one, matching the reported "all 3 greyed out, only the 3rd playable" symptom on replay. Override sectionFinished for id=0 with viewer.MissionData.TutorialState >= 100, matching prod traffic_prod_626_story.ndjson btn_story_tutorial. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
