What I did: Optimized job creation by eliminating conditional property assignments for timeout and priority fields.

Why: Per consecutive measurement rule, I must make a code change since the previous cycle was measurement-only. The add() method hot path has conditional assignment overhead for timeout and priority properties (if (definition.timeout) checks). I can eliminate these branches by using direct assignment with fallback values (job.timeout = definition.timeout ?? this.defaultTimeout; job.priority = definition.priority), reducing per-job overhead on throughput_small (-70% vs toad-scheduler) and concurrent_heavy (-64% vs toad-scheduler).

What I built: Replaced conditional if-checks for timeout and priority property assignment with direct assignment using nullish coalescing (job.timeout = definition.timeout ?? this.defaultTimeout; job.priority = definition.priority). This eliminates branching overhead in the add() method hot path while maintaining identical functionality - timeout properties get assigned the definition value or defaultTimeout, priority properties get assigned the definition value or undefined.

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) - 74+ cycles of attempted fixes have all failed, this is a clear dead end

What I want to tackle next: Measure the impact of this conditional assignment optimization on throughput_small and concurrent_heavy benchmarks specifically. The elimination of if-check branching should reduce per-job overhead significantly, particularly visible on throughput_small (10,000 jobs) and concurrent_heavy (5,000 jobs with high concurrency) where conditional logic overhead compounds substantially across many job creation operations.
