  "title": "Native coding-agent continuation across providers",
  "summary": "On 7 September 2026, three hosted assertions passed with the actual tested coding-agent application and real tool use. A fixture task continued after a checkpoint-boundary provider change and produced an independently verified artifact. Lineage and metering remained continuous; a disabled continuation path failed closed and fallback completed after restoring the workspace. The agent ran in an isolated copy of its environment, with transport tested separately. Quality remains model-dependent, and streaming was buffered rather than incremental.",
