WOWII Conjecture 100 has been resolved

Written on the Wall II Conjecture 100, currently listed in Formal Conjectures as research open, has been resolved.

Ermelinda DeLaVina, the maintainer of the Written on the Wall II conjecture collection, reviewed the submitted proof, confirmed the intended definition of the length invariant, stated that she believes the proof is correct, and updated the original WOWII webpage to mark Conjecture 100 as true.

The proof is publicly archived on Zenodo:

Kias Henry, “A Proof of Written on the Wall II Conjecture 100”
DOI: 10.5281/zenodo.21914031

The proof establishes a slightly stronger strict inequality from which Conjecture 100 follows.

Could WrittenOnTheWallII/GraphConjecture100 therefore be reviewed for updating from research open to research solved?

I would also be interested in contributing a Lean formalization of the proof.

Start with the WrittenOnTheWallII/GraphConjecture100 entry in the Formal Conjectures collection and compare its current research status with the linked Zenodo proof and the updated WOWII webpage. Done means the entry is reviewed and updated from research open to research solved, or the needed follow-up is recorded; the proposed Lean formalization is a separate, larger task.
