New analytical lens tested on gargoyle order-state-machine.md:
- GPT-5: 15 findings (most CRITICAL issues, exhaustive field analysis)
- Opus: 14 findings (state lifecycle focus, implementation mechanisms)
- Sonnet: 10 findings (fast but shallow)
Key insight: "unstated constraints" finds what's IMPLIED but not stated,
distinct from gaps, race conditions, or ambiguities. GPT-5 is best for
catching CRITICAL data integrity constraints; Opus for state machine
implementation details.
