This puzzle's semantic breakdown

"proof" has a moderately defined neighborhood. The closest word is "proofs" at 0.701 similarity, and the top-10 average is 0.584. "proofs", "irrefutable", "prove" form its core cluster, but the edges are soft — you need a few probes to home in.

Similarity slides smoothly from 0.701 to 0.385 at rank 100, a total span of just 0.317. This word rewards patient triangulation over a single lucky stab.

The hidden thread this round is "disprove" (0.574). It belongs to a different branch than the leader "proofs", so intuitive guessing rarely lands on it — but once it clicks, the puzzle opens up.
