Written on the Wall II, Conjecture 198a

A candidate mathematical proof of Conjecture 198a emerged relatively quickly. Converting it into a complete Lean proof required substantially more proof engineering and verification.

Start by reading the linked paper and the exact theorem in lean/src/ConditionalMain.lean at lines 52–57 in the referenced repository. Determine how this formalization should be represented in formal-conjectures and verify the resulting Lean statement and proof against the cited result.
