fix(meta): erdos-25 register Erdos25LogDensity.lean orphan companion#21918
Merged
Conversation
Primary file Erdos25Problem.lean:16 imports Proofs.Erdos25LogDensity, but the companion file was absent from both meta.additionalFiles and leanFile.additionalFiles — making it an orphan. The companion is already referenced in prose: meta.assumptions attributes the 3 axioms to it, and meta.overview.proofStrategy cites "defined constructively via Erdos25LogDensity.lean". Registered in both meta.additionalFiles and leanFile.additionalFiles per the canonical mirror convention. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
