Re-Extension Logic

When re-extension exists

Re-extension only occurs if both sides of the target session range are swept before the entry window opens.

Examples: - NY mode: both sides swept between 05:00 and 07:00 ET - London mode: both sides swept between 00:00 and 02:00 ET

Result

The original range is cleared. A re-extended range is created using the extremes of the sweep moves.

Bot behavior

The system must: 1. detect original range 2. scan the gap window 3. determine whether re-extension exists 4. invalidate the day if the re-extended range also gets both sides swept
