Extends the instrument-grpc rewrite to log string (strHandle) + uint (uiHandle /
queryRequestType) params, not just byte[], and captures our SDK's live v8
openParameters for a byte-diff against the native.
Result of the exhaustive comparison (all live-confirmed via the opt-in
EventReadDiagnostic test):
- StartEventQuery request: byte-identical to the native (v6 layout)
- v8 OpenConnection openParameters: byte-identical to the native (302B) once
ClientNodeName matches — every control byte/ConnectionType/token/ShardId
- handle usage identical: ExchangeKey->contextKey, registration->storage GUID
(strHandle), query->client uint (uiHandle); handles valid (RTag/EnsT=True)
- queryRequestType=3, registration order, gzip metadata header — all match
- window has events (native returns 50 now); eventCount not it
Every observable client-side byte matches the native, yet the server scopes 0
events to our connection. The event RPCs succeed over our transport and return a
valid EMPTY result (not a transport error), so this is a connection/server-level
difference (session affinity tied to the native Grpc.Core HTTP/2 connection or a
connection identity used to scope events) — invisible to and unfixable by client
payload matching. Needs server-side insight, not more wire RE.
Added opt-in diagnostics (RegistrationDiag, LastResultBufferHex,
LastEventOpenRequestHex). 326/326 offline; gated test still pins the no-row throw.
