Execute HCAL roadmap R1.2 (GetRuntimeParameterAsync) end-to-end, and in doing so
discover that the "string-handle wall" blocking R1.1/R1.4/R1.5/R1.6 was a handle
FORMAT bug, not a missing native session/filter registration.
R1.2 (shipped, live-verified):
- Captured native GetRuntimeParameter -> WCF op aa/Stat/GETRP (string-handle op,
GETHI's shape), via scripts/Capture-RuntimeParam.ps1 + instrument-wcf-{write,read}message.
- HistorianRuntimeParameterProtocol serializes pRequestBuff (54 67 01 00 + uint
nameCount + per-name uint charCount + UTF-16) and parses pResponseBuff (version +
uint resultCount + CRetVariant 0x43 VT_BSTR + uint16 len + uint16 charCount + UTF-16).
- IStatusServiceContract2.GetRuntimeParameter (GETRP) op; HistorianWcfStatusClient
passes the Open2 storage-session GUID as the string handle, UPPERCASE.
- Public HistorianClient.GetRuntimeParameterAsync(name) via the dialect.
- Golden WcfRuntimeParameterProtocolTests + gated live test; returns HistorianVersion.
String-handle wall RESOLVED (proven, public APIs deferred):
- The Open2 storage GUID works as the string handle when sent UPPERCASE
(ToString("D").ToUpperInvariant()); earlier "blocked" probes used lowercase.
- Live-probed GETHI (R1.4) -> returns data; ExeC (R1.1) -> Retr.GetV prime -> ExeC ->
GetR returns a BinaryFormatter-serialized .NET DataTable. Gated
StringHandleProbeDiagnosticTests + scripts/Capture-ExecSql.ps1 + exec-sql harness scenario.
- Docs flipped: wcf-string-handle-wall.md RESOLVED banner; roadmap R1.1/R1.4 reachable,
R1.5/R1.6 likely; wcf-status-localhost.md GETRP section.
- R1.1/R1.4 public APIs NOT shipped: ExeC needs a GetR paging loop + a BinaryFormatter-
stream parser (BinaryFormatter is removed from .NET 10); GETHI full-info struct needs
its own capture.
223 unit tests pass; gated live tests green against the local 2020 Historian.

.SYNOPSIS
|
|
Captures the native AVEVA client's ExecuteSqlCommand wire traffic (HCAL roadmap R1.1) so the
|
|
Retr.ExeC + Retr.GetR string-handle SQL surface (op names, handle format, command/option
|
|
encoding, Retr priming, GetR result byte stream) can be decoded instead of guessed.
|
|
|
|
.DESCRIPTION
|
|
Drives the .NET-Framework NativeTraceHarness `exec-sql` scenario against the live Historian
|
|
with an IL-rewritten copy of aahClientManaged.dll whose ClientMessageEncoder.WriteMessage AND
|
|
ReadMessage are instrumented to log every MDAS body. Read-only benign query.
|
|
|
|
.NOTES
|
|
Artifacts are diagnostic and gitignored. Sanitize before copying into docs/ -- never commit raw
|
|
capture NDJSON, credentials, hostnames, or customer tag names.
