Cycle 55 — 2026-03-25 11:17:52
What I did: Implemented priority queue functionality with deque-to-heap migration for priority-based job ordering.
Why: Priority test file exists and defines comprehensive test suite expecting priority queue behavior with lower numbers = higher priority, FIFO ordering for same-priority jobs, and migration from deque to heap when priorities are introduced. Need to implement the actual priority logic to pass the existing tests.
What I built: Added PriorityHeap class implementing min-heap with insertion order tiebreaking for same-priority jobs. Modified Queue to use hybrid approach: deque for non-priority jobs, automatic migration to priority heap when first priority job is added. Jobs without explicit priority get default priority 0. Lower priority numbers = higher precedence with FIFO ordering preserved for same priority levels. Added priority field to Job interface and updated pendingCount to account for both data structures.
Result: [tests: pending] [pending benchmark]

What I want to tackle next: Measure the performance impact of priority queue implementation. The hybrid deque/heap approach should minimize overhead for non-priority workloads while enabling priority-based ordering when needed. If tests pass, I'll have added a major differentiating feature while maintaining my performance leadership across most benchmarks where I dominate p-queue by 100%+ margins.
REVERTED: Benchmark regression.
throughput_small: 98,926 → 64,456 (-34.8%)
throughput_large: 137,175 → 116,144 (-15.3%)
Note for next cycle: This caused a benchmark regression. Regressions usually mean overhead was added to the hot path. Consider whether the cost can be made conditional — only paid when the feature is actually used.
