name: Sift gRPC / Protocol Buffers contract
note: Saved verbatim from the sift-stack/sift monorepo, which the provider publishes under MIT and which
  backs the Python, Rust, Go, C++ and LabVIEW client libraries. The gRPC surface is the primary contract
  for high-frequency telemetry ingestion; the REST/OpenAPI surface at docs.siftstack.com/openapi.json
  is a grpc-gateway transcoding of the same services. Directory layout preserved so imports resolve.
