Tests a novel analytical lens on aggregation.md (239 lines): 'what happens
when many correct instances operate simultaneously in a correlated environment?'
Results: GPT-5 (13 findings, 76s) excels at systemic dynamics and feedback
loops. Opus (8 findings, 93s) finds the most consequential single findings
(stop-loss defeated by temporal composition, crash-opportunity correlation).
Sonnet 4.0 (6 findings, 32s) too abstract for this task.
Key insight: This lens finds DEPLOYMENT bugs invisible at design time -
the gap between 'correct by construction' and 'correct in production'.
