Case file LinkedIn Crossclimb #887: 4-letter ladder, 5 middle exhibits, combo prompt "Two consecutive letters in the NATO phonetic alphabet.". Endpoints: KILO (top) and LIMA (bottom).
Middle phase answers: "Pleated garment associated with Scotland" = KILT; "Lean over a little" = TILT; "Piece of material often used to cover a floor or wall" = TILE; ""___ flies when you're having fun"" = TIME; "Green citrus fruit" = LIME.
Ordering phase: the valid middle chain is KILT → TILT → TILE → TIME → LIME. This permutation is the only valid one-letter chain for these answers.
Evidence link: KILO → KILT. O→T at the fourth letter (KILO → KILT).
Evidence link: KILT → TILT. K→T at the first letter (KILT → TILT).
Evidence link: TILT → TILE. T→E at the fourth letter (TILT → TILE).
Evidence link: TILE → TIME. L→M at the third letter (TILE → TIME).
Evidence link: TIME → LIME. T→L at the first letter (TIME → LIME).
Evidence link: LIME → LIMA. E→A at the fourth letter (LIME → LIMA).
Verdict: KILO → KILT → TILT → TILE → TIME → LIME → LIMA satisfies every one-letter constraint. The combo clue "Two consecutive letters in the NATO phonetic alphabet." describes both end words together — "KILO" and "LIMA" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
