ai:agent

Autonomous multi-agent performance optimization loop for Chromium and V8. Supports profile-seeded mode (analyzing Speedometer 3 / JetStream profiles via pprof or Sagacity MCP) and pattern-driven discovery mode (fan-out exploration of Blink and V8 macro-patterns grounded in historical wins and past rejected CLs). Dispatches isolated implementations in git worktrees, verifies local tests, uploads CLs, triggers 150-iteration Pinpoint try jobs on Apple Silicon M1 hardware, pipelines subsequent hypotheses asynchronously, evaluates statistical significance, and manages CL lifecycles.
