Stands up HistorianTransport.RemoteGrpc end-to-end for the read path, built on the recovered 2023 R2 gRPC contract (gRPC-Web/HTTP-1.1, port 32565, gzip). The opaque protobuf `bytes` fields carry the SAME native binary payloads as the 2020 WCF/MDAS path, so the proven serializers and parsers are reused unchanged. - Grpc/Protos/*.proto: 6 protoc-validated contracts recovered from embedded FileDescriptors (authoritative, not guessed). - Grpc/HistorianGrpcChannelFactory: GrpcWebHandler/HTTP-1.1 channel, ResolvePort/ResolveAddress, optional TLS + gzip. - Grpc/HistorianGrpcReadOrchestrator: mirrors the WCF read chain over gRPC; auth uses HistoryService.ExchangeKey (the gRPC ValCl op). - Wcf/HistorianNativeHandshake: transport-agnostic Open2 request builder + SSPI/Negotiate token loop + response decode, shared by WCF and gRPC. - Op map (2020 -> gRPC): ValCl->ExchangeKey, Open2->OpenConnection, StartQuery2->StartQuery, GetNextQueryResultBuffer2->GetNextQueryResultBuffer. - HistorianClientOptions: DefaultGrpcPort=32565, GrpcUseTls. - csproj: Google.Protobuf, Grpc.Net.Client(.Web), Grpc.Tools codegen. Not yet live-verified against a 2023 R2 server: ExchangeKey is the first thing to revisit if a live server rejects the handshake; the inner byte payloads are the proven 2020 protocol. Gated live test via HISTORIAN_GRPC_HOST. 188 unit tests green; build clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
