Pull the exact quoted sentence from Gale's 1979 paper stating the Hex/Brouwer fixed-point equivalence

claim-gale-1979-hex-draw-impossibility-equivalent-to-brouwer-fixed-point cites a Tier 1 primary — David Gale's own 1979 American Mathematical Monthly article, "The Game of Hex and the Brouwer Fixed-Point Theorem" (PDF at cijm.org, courtesy of Loïc Cellier) — but the capture that surfaced it recorded only a paraphrase of the equivalence, not the exact sentence(s) where Gale states it. Source-preservation practice requires the precise quoted phrase for Tier 1–2 claims, not just a paraphrase.

What to read / pull:

What it gates: moving the note off seedling / clearing its [unverified-quote] flag. Also underpins the three-way Hex thread linking claim-shannon-moore-1950-analog-hex-machine-move-as-saddle-point and claim-nash-hex-first-player-win-proof-is-non-constructive.
