Briefing

Keep every bell row, but stamp each with its wing's total volume — partition, don't GROUP away the notes.

Objective

Return wing, note, and SUM(volume) OVER (PARTITION BY wing) as wing_total, ordered by wing then note.

Hint

PARTITION BY wing resets the window sum per wing.

I am the Warden. Ask for a hint, paste a failing query, or request a review — I won't hand you the full answer.
