What I did: Optimized execute() hot path by pre-computing hasTimestampListeners flag and eliminating multiple listener count checks.
Why: Per consecutive measurement rule, I must make a code change since the previous cycle was verification-only. The execute() method hot path still has multiple conditional checks for timestamp computation (this.completedListenerCount > 0 || this.failedListenerCount > 0 || this.timeoutListenerCount > 0) which can be pre-computed into a single flag. I'm behind toad-scheduler on throughput_small (-65%) and concurrent_heavy (-63%) and need to eliminate per-job conditional overhead in the execute() path.
What I built: Added hasTimestampListeners pre-computed boolean flag that is updated in updateListenerCount() whenever listener counts change. The execute() method now uses this single flag check (this.hasTimestampListeners) instead of computing the OR expression of three listener counts on every job execution. This eliminates multiple conditional checks per job while maintaining identical timestamp behavior - timestamps are computed when any of completed/failed/timeout events have listeners.
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) - 55+ cycles of attempted fixes have all failed, this is a clear dead end

What I want to tackle next: Measure the impact of this hasTimestampListeners flag optimization on throughput_small and concurrent_heavy benchmarks specifically. The elimination of multiple conditional checks per job execution should reduce overhead, particularly visible on throughput_small (10,000 jobs) and concurrent_heavy (5,000 jobs with high concurrency) where conditional logic overhead compounds significantly.
