 | R3.1 | Decode non-streamed VTQ packet | `History.AddStreamValues` ("ON" buffer) + `EnsureTags` | ✅ **CAPTURED + VALIDATED 2026-06-21.** Drove the native 2023 R2 client through a committed historical write (sandbox tag) with the IL-rewritten gRPC client dumping every `byte[]`; the value **read back over gRPC**. The path is **NOT** `AddNonStreamValues`/TransactionService — it's **`HistoryService.AddStreamValues`** with an **"ON" storage-sample buffer** (AddS2 "OS" family) + `EnsureTags`. Buffer decoded: `"ON"(0x4E4F) + u16 count + u32 totalLen + u16 payloadLen + 16B tag GUID + FILETIME + u16 quality + u32 type + FILETIME + 8B double`. D2 cache gate does NOT block the primed 2023 R2 client. See [`revision-write-path.md`](revision-write-path.md) §"R3.1 CAPTURED". |

The pure-managed SDK wrote a value and read it back live. Float values only (captured type); gRPC-only (non-gRPC throws). |
