Confirms the pi §2.3 four-frame table (from {} through path partial through path+content partial to sealed). Wire shape follows packages/llm/llm/src/types.ts:116 (StreamChunk union member tool-call-delta { index, id, name?, argumentsDelta }). Second call: run_bash streamed across 3 slices so aggregator tests exercise more than one open row."
