Classification target LinkedIn Crossclimb #839. Ladder width: 4. Middle samples: MASS, MAST, CAST, COST, COAT. Combo label: "Two words that complete the expression “___ the ___” meaning to lose out on an opportunity (i.e., the ship’s already left!).". Full chain: MISS → MASS → MAST → CAST → COST → COAT → BOAT.
Middle phase answers: "Physical property measured in grams" = MASS; "Tall pole used to support a sail" = MAST; "Fiberglass bandage used to immobilize a broken bone" = CAST; "It’s listed on a price tag" = COST; "Outerwear to protect from the cold and rain" = COAT.

Transition 1: I→A at the second letter (MISS → MASS).
Transition 2: S→T at the fourth letter (MASS → MAST).
Transition 3: M→C at the first letter (MAST → CAST).
Transition 4: A→O at the second letter (CAST → COST).
Transition 5: S→A at the third letter (COST → COAT).
Transition 6: C→B at the first letter (COAT → BOAT).
Ladder result: MISS → MASS → MAST → CAST → COST → COAT → BOAT. Classification: unique middle order.
