The capture-write harness scenario drives the native 2023 R2 client through a non-streamed
(historical backfill) write so the IL-rewritten GrpcHistoryClient dumps RegisterTags.tagInfos +
AddNonStreamValues.inBuff to the capture NDJSON. Sequence: open write-enabled gRPC -> (optional
--create) AddTag sandbox -> GetTagInfoByName (real TagKey + primes the per-connection cache, the
gate mitigation) -> CreateHistorianDataValueList(NonStreamedOriginal) -> NonStreamedValuesBegin ->
AddNonStreamedValue -> AddNonStreamedValuesEnd -> SendValues (the wire push; only with --commit).
Not yet run — the actual write to the live server awaits explicit confirmation. Built clean.
