+- User accepted full-stop correction. Continued with flight only: title, message and mission description (literal indexes 12–14). Two concise centered paragraphs retain mouse destination, altitude globe and keyboard movement instructions.
+- All other text and non-display bytes preserved; the original movement threshold (>15 units along either horizontal axis within the timed loop) and next-button gating remain unchanged. Flight height/attack are next batches.
+- 35 tests pass, including engine layout at widths 360/400/480; original/modified byte verification and rollback passed. Backup: `E:/DragonHD/backup_game/tutorial-flight-20260920/Tutorial.dsc`.
+- Game stopped using user's prior termination authorization; deployed file reread and matched output. SHA256: `a41caad224f748222489f8d062526ae663bb04201c593f59d6af02d69a74f604`.
+- In-game acceptance pending: enter Flight after Zoom, use left click or arrow keys to move some distance, then check Continue Tutorial becomes available and Flight height starts.
