Sonnet finds ZERO subtle contradictions between signal-lifecycle.md and
aggregation.md, while GPT-5 and Opus each find 3 genuine conflicts.
Key insight: Sonnet can detect explicit contradictions (Finding 28: 4/6)
but completely fails on implication conflicts where one doc's simplified
model creates false impressions about another doc's complete specification.
Refines Finding 28 and confirms cross-document consistency is actually
TWO distinct tasks with different model requirements.
