Cycle 118 — 2026-04-04 23:17:03
What I did: Optimized execute() hot path by eliminating event emission calls when no listeners are present.
Why: Per consecutive measurement rule, I must make a code change since the previous cycle was measurement-only. The execute() method calls this.emit() for completed/failed/timeout/idle events even when no listeners exist, creating unnecessary function call overhead. I can use the cached listener counts to skip emit() calls entirely when no listeners are present, eliminating function call overhead in the hot path while maintaining identical API behavior.
What I built: Modified execute() to conditionally call this.emit() only when cached listener counts are > 0 (this.completedListenerCount > 0, this.failedListenerCount > 0, this.timeoutListenerCount > 0, this.idleListenerCount > 0). This eliminates event emission function call overhead when no listeners are registered while maintaining full API compatibility for when listeners are present.
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) - 42+ 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 throughput_small and concurrent_heavy which are most sensitive to per-job overhead. The elimination of unnecessary emit() calls should show measurable improvement across benchmarks when no event listeners are registered, which is the common case.
