  "message": "ui: aggregate counter tracks by args in the area selection\n\nThe counter area-selection aggregation pre-aggregated per track and\nexposed no args, so it couldn\u0027t be broken down. Return per-sample rows\nwith a `delta` (increase since the previous sample on the track) and a\nparameterized `args.*` column (extract_arg on arg_set_id), mirroring the\nslice aggregator\u0027s `dur` pivot. Counters can now be grouped by name or by\nany arg, with count and sum-of-increase per group.\n",
