Case file LinkedIn Crossclimb #827: 4-letter ladder, 5 middle exhibits, combo prompt "A two-word name for a port city that is the legislative capital of South Africa.". Endpoints: CAPE (top) and TOWN (bottom).
Middle phase answers: "Sticky strip that can be used instead of glue" = TAPE; "Light hits" = TAPS; "Gets a lot of rays at the beach" = TANS; "A great amount, or units to describe something weighing 10,000 pounds" = TONS; "Pulls an automobile to a repair shop" = TOWS.
Ordering phase: the valid middle chain is TAPE → TAPS → TANS → TONS → TOWS. This permutation is the only valid one-letter chain for these answers.
Evidence link: CAPE → TAPE. C→T at the first letter (CAPE → TAPE).
Evidence link: TAPE → TAPS. E→S at the fourth letter (TAPE → TAPS).
Evidence link: TAPS → TANS. P→N at the third letter (TAPS → TANS).
Evidence link: TANS → TONS. A→O at the second letter (TANS → TONS).
Evidence link: TONS → TOWS. N→W at the third letter (TONS → TOWS).
Evidence link: TOWS → TOWN. S→N at the fourth letter (TOWS → TOWN).
Verdict: CAPE → TAPE → TAPS → TANS → TONS → TOWS → TOWN satisfies every one-letter constraint. The combo clue "A two-word name for a port city that is the legislative capital of South Africa." describes both end words together — "CAPE" and "TOWN" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
