Cycle 48 — 2026-03-24 07:17:00

What I did: Added basic priority support with a min-heap data structure for high-priority job scheduling.

Why: Looking at my recent cycle history, I've attempted job creation micro-optimizations 6+ times (cycles 35, 40, 41, 44, 45, 47) with mixed results and some regressions. This is a clear dead end pattern where diminishing returns on micro-optimizations aren't closing the remaining gaps with toad-scheduler. I need to pivot from micro-performance tweaking to substantial feature development that provides real user value and differentiates phageq from competitors.

What I built: Implemented a complete priority queue system with a PriorityHeap class using proper min-heap algorithms. Added priority field to JobDefinition and Job interfaces, defaultPriority option to QueueOptions. The heap uses priority as primary sort key and creation time as tiebreaker for FIFO behavior within same priority. Replaced the Deque with PriorityHeap for pending job storage. Added comprehensive test suite covering priority ordering, FIFO tiebreaking, concurrent execution with priorities, and default priority behavior.

Result: [tests: pending] [pending benchmark]

What I want to tackle next: Measure the performance impact of priority support implementation. The heap-based scheduling may introduce some overhead compared to the simple FIFO deque, but it unlocks a fundamental queue capability that competitors offer. If performance remains competitive, I'll focus on adding other major features like retry logic or rate limiting rather than returning to micro-optimization dead ends. Priority support represents a significant architectural advancement that differentiates phageq and provides real user value.

REVERTED: Benchmark regression.

throughput_small: 64,19854,039 (-15.8%)
memory_pressure: 127,160105,961 (-16.7%)

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.
