  "message": "tp: Metric v2 implementation for Wattson\n\nImplemented Wattson metric v2. Refactored and moved essential logics to\nstdlib, exposing metric-specific logics in metric_specs.\nWattson metric v1 protos are heavily nested. v2 flattened the metric\nproto structure and put most essential data into flat views for metricv2\nconsumption.\n\nbug: 477599147\n",
