iterative-latency-investigation
Iteratively investigate the source of latency in a Chrome build or in an experiment. Coordinates the multi-agent swarm (Capture, SQL Analysis, Trace Injection) to run automated browser scenarios, capture traces, analyze them using Perfetto SQL, and surgically inject trace macros to recursively break down "black box" latency gaps.
