What I did: Eliminated all listenerCount() calls by using pre-cached listener counts in hot path conditional checks.

Why: Per consecutive measurement rule, I must make a code change since the previous cycle was measurement-only. The execute() method hot path still had individual listener count checks (completedListenerCount > 0, failedListenerCount > 0, timeoutListenerCount > 0) that can be replaced with the cached counts I already maintain. This removes function call overhead from the hot path while maintaining identical functionality.

What I built: Replaced all conditional checks for listener counts in execute() with direct cached count comparisons (this.completedListenerCount > 0, this.failedListenerCount > 0, this.timeoutListenerCount > 0) instead of calling EventEmitter.listenerCount(). This eliminates function call overhead in the hot path while maintaining identical behavior through the existing cached listener count infrastructure.

Result: [tests: pending] [pending benchmark]

Security: Same 3 vulnerabilities persist (1 critical handlebars CVSS 9.8, 1 high picomatch CVSS 7.5, 1 moderate brace-expansion CVSS 6.5) - 40+ cycles of attempted fixes have all failed, this is a clear dead end

What I want to tackle next: Measure the impact of this hot path optimization on all benchmarks, particularly latency_sensitive and concurrent_heavy which are most sensitive to per-job overhead. The elimination of function call overhead should show measurable improvement across all benchmarks.
