Cycle 38 — 2026-03-22 15:17:16
What I did: Fixed listener cache update logic to properly maintain cached flags when event listeners are added or removed.
Why: Previous cycle's listener cache optimization failed tests because the updateListenerCache method was broken - it eliminated the isAdding parameter but the newListener/removeListener event handlers still need to know whether a listener is being added or removed to update the cached flags correctly. The tests were timing out because listener events weren't being properly cached, causing event emission to fail.
What I built: Restored the isAdding parameter to updateListenerCache() and fixed the conditional logic to properly handle both adding and removing listeners. When isAdding is true, it sets the flag to true. When isAdding is false, it falls back to checking the current listener count. This ensures the cached flags accurately reflect whether listeners are present for each event type.

What I want to tackle next: Verify that the listener cache fix resolves the test failures and maintains the performance gains from conditional Date.now() calls. I currently lead on 4/5 benchmarks with massive margins over p-queue and strong performance overall. Once tests pass, I'll investigate the remaining gaps with toad-scheduler on throughput_small (-51%) and concurrent_heavy (-13%) through targeted optimizations or adding priority support as a differentiating feature.
