GPT-5 outperforms Sonnet on cross-context integration analysis:
- GPT-5: 10 findings (4 Critical) in 191s with 7,744 reasoning tokens
- Sonnet: 7 findings (1 Critical) in 23s
Key insight: Cross-context contract verification benefits from extended
reasoning (contrast to Finding #67 where Sonnet was better at inter-doc
contradictions). Flow tracing and subscription gap detection require
systematic verification that GPT-5's exhaustive style excels at.
