  "message": "tp+ui: resolve process/thread names for (is_pid)/(is_tid) args\n\nArgs produced from an (is_pid)/(is_tid) proto field annotation carried a\nresolved upid/utid but were stored as a plain integer, so the UI showed a bare\nnumber with no way to see or group by the process.\n\nA upid/utid is an int with a semantic annotation, not a new primitive type. A\nnew Variadic type would touch every exhaustive Variadic::Type switch; instead a\nside table records the annotation, keeping the args schema and value_type\nuntouched and leaving room for multiple annotations per key.\n\ntrace_processor:\n  - New __intrinsic_arg_annotation(key, annotation) table (SQL view\n    arg_annotation). An annotation is a property of the key, so each\n    (key, annotation) is stored once, not per arg set. AddUpid/AddUtid store\n    Variadic::Integer and tag the arg \u0027upid\u0027/\u0027utid\u0027; the tag threads through\n    ArgsTracker / GlobalArgsTracker, which writes each distinct pair once.\n  - arg_set_to_json loads the (small) annotation table once and, next to a\n    \u003c...\u003eupid/\u003c...\u003eutid arg, emits a companion \u003c...\u003eprocess_name/\u003c...\u003ethread_name\n    resolved from the process/thread table at query time, so always the final\n    name. The details panel shows it with no UI-side work.\n\nui (datagrid): the slice-selection aggregator\u0027s args selector exposes the same\ncompanion name key and resolves it by joining arg_annotation on key.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e\nChange-Id: Ibd68b0625dfb88af307c52ca4a6785c99140d0a6\n",
