Ship SQL command execution over the 2020 WCF aa/Retr/ExeC + aa/Retr/GetR ops: HistorianClient.ExecuteSqlCommandAsync(sql) -> HistorianSqlResult (columns + typed rows). String-handle ops reached with the Open2 storage-session GUID formatted uppercase (the handle format that unlocked GETRP/GETHI). Chain: Retr.GetV prime -> ExeC(handle, sql, option=0, ref queryHandle) -> GetR loop. Key gotcha captured: GetR returns FALSE even on success -- the byte stream is in pResultBuff regardless; false just signals the final page. So the orchestrator consumes the buffer first, then stops on a false result / empty page. GetR's pResultBuff is an NRBF-serialized System.Data.DataTable (SerializationFormat.Xml: members XmlSchema (XSD) + XmlDiffGram (rows)). BinaryFormatter is removed from .NET 10, so the stream is decoded read-only with the System.Formats.Nrbf package (NrbfDecoder) + XDocument -- no BinaryFormatter, no code execution. Values are typed per the XSD type, falling back to string. Adds: HistorianSqlResult / HistorianSqlColumn / HistorianSqlExecuteOption models, HistorianSqlResultProtocol (NRBF + diffgram parser), HistorianWcfSqlClient (ExeC/GetR orchestration with an AVEVA_HISTORIAN_SQL_DUMP diagnostic), dialect + public API. Golden WcfSqlResultProtocolTests pinned to the real clean GetR stream for the benign "SELECT 1 AS ProbeValue" (no sensitive data); gated live tests (single cell + multi-column/multi-row/NULL). Doc: wcf-exec-sql.md; roadmap R1.1 DONE; wall doc + memory updated (incl. the QTB-server-side nuance). 229 tests green. Note: a raw instrument-wcf capture corrupts a large pResultBuff with MDAS transport chunk markers (0x9F); the clean contract-level byte[] is dumped via the AVEVA_HISTORIAN_SQL_DUMP env var for the golden fixture.
