2. COAL → COATStep 2

   L→T at the fourth letter (COAL → COAT)

   COAL and COAT are adjacent in the solved ladder — L→T at the fourth letter (COAL → COAT).

   Step 2: Valid only if exactly one letter differs; middle-to-middle link.

3. COAT → BOATStep 3

   C→B at the first letter (COAT → BOAT)

   COAT and BOAT are adjacent in the solved ladder — C→B at the first letter (COAT → BOAT).

   Step 3: Valid only if exactly one letter differs; middle-to-middle link.

4. BOAT → BOOTStep 4

   A→O at the third letter (BOAT → BOOT)

5. BOOT → ROOTStep 5

   Step 6: Valid only if exactly one letter differs; this step touches a combo end.

After solving middles (COAL, COAT, BOAT, BOOT, ROOT), only the order COAL → COAT → BOAT → BOOT → ROOT satisfies the one-letter rule between every adjacent pair. Each step changes exactly one letter: O→A at the third letter (COOL → COAL); L→T at the fourth letter (COAL → COAT); C→B at the first letter (COAT → BOAT); A→O at the third letter (BOAT → BOOT); B→R at the first letter (BOOT → ROOT); T→F at the fourth letter (ROOT → ROOF). Wrong permutations fail when two middles differ by two or more letters.

The combo clue "Chilly shelter overhead" describes both end words together — "COOL" and "ROOF" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt. Top "COOL" connects to COAL via O→A at the third letter (COOL → COAL). Bottom "ROOF" connects from ROOT via T→F at the fourth letter (ROOT → ROOF).

The combo clue "Chilly shelter overhead" describes both end words together — "COOL" and "ROOF" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
