Cycle 105 — 2026-04-02 19:17:02

What I did: Optimized execute() hot path by eliminating Date.now() call for startedAt when no event listeners need the timestamp.

Why: Per consecutive measurement rule, I cannot run two measurement cycles in a row after the previous measurement cycle. Looking at the execute() hot path, job.startedAt = Date.now() is called for every single job but the timestamp is only used by event listeners. The latency_sensitive benchmark runs 1000 jobs sequentially and any per-job overhead compounds - eliminating unnecessary Date.now() calls should improve performance significantly.

What I built: Modified execute() method to conditionally set job.startedAt only when event listeners that might use the timestamp are present (completedListenerCount > 0 || failedListenerCount > 0 || timeoutListenerCount > 0). When no relevant listeners exist, job.startedAt is set to 0 to avoid the Date.now() system call overhead. Added comment marking this as "ultra-fast hot path" optimization.

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) - this is a dead end after 29+ cycles

What I want to tackle next: Measure the impact of this execute() hot path optimization on latency_sensitive benchmark specifically. If successful, continue optimizing by eliminating other unnecessary operations in the execute flow when no listeners are present.
