New analytical lens applied to signal-lifecycle.md (111 lines).
All three models (GPT-5, Opus, Sonnet) found 7-9 findings each with
70% at Critical/High severity. Key insight: concurrency analysis
rewards compositional temporal reasoning over enumeration breadth,
narrowing the gap between models compared to other lenses.
Unique finds: GPT-5 (stop-loss race, duplicate UUID), Opus (crash
survival contradiction), Sonnet (Signal Risk audit gap after dispatch).
