The sheet
Every sole is a small river. The quad either maps the bend or it lies.
Sheet 7 does not debate a grind letter. Quillan inks a neatline, Tova traces leading and trailing, Rudi writes keep, recut, or refused.
Neatline before nickname
A sole that says "C" is a rumor until the contours agree. We trace entry, then exit, then we write the meander Columbia silt actually uses.
One legend per head
A 54 and a 58 claiming the same meander is a collision. One contour moves. Kindness that leaves both on the cart is how Waterfront Park scores get invented.
