Case file LinkedIn Crossclimb #847: 4-letter ladder, 5 middle exhibits, combo prompt "A hyphenated word describing someone who is highly educated through books.". Endpoints: WELL (top) and READ (bottom).
Middle phase answers: "Plunged" = FELL; "Soft green material on a poker table" = FELT; "It may hold up your jeans" = BELT; "Quality of a danceable song" = BEAT; "Stone with a hole in it used in jewelry" = BEAD.
Ordering phase: the valid middle chain is FELL → FELT → BELT → BEAT → BEAD. This permutation is the only valid one-letter chain for these answers.
Evidence link: WELL → FELL. W→F at the first letter (WELL → FELL).
Evidence link: FELL → FELT. L→T at the fourth letter (FELL → FELT).
Evidence link: FELT → BELT. F→B at the first letter (FELT → BELT).
Evidence link: BELT → BEAT. L→A at the third letter (BELT → BEAT).
Evidence link: BEAT → BEAD. T→D at the fourth letter (BEAT → BEAD).
Evidence link: BEAD → READ. B→R at the first letter (BEAD → READ).
Verdict: WELL → FELL → FELT → BELT → BEAT → BEAD → READ satisfies every one-letter constraint. The combo clue "A hyphenated word describing someone who is highly educated through books." describes both end words together — "WELL" and "READ" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt.
