**Stack 4/5** — base #4125. Part of the #4096 split; see #4096 for the overall picture. > Review after #4123, #4124 and #4125. ## What this is The generic OPC UA to OpenUSD binding, scene materialization, and the connector that drives a live stage from a running server. ## Contents **Binding (Part 1)** — `Opc.Ua.OpenUsd` and `Opc.Ua.OpenUsd.Server`. A server describes how its Variables drive USD prims, and serves the USD layers it refers to as Part 5 files with a content digest. **Scene materialization (Part 2)** — `Opc.Ua.OpenUsdScene` and `Opc.Ua.OpenUsdScene.Server`, including the USDA writer. - **Escaping fix**: string values, composition-arc references, variant set names and selections, `doc` and prim names were all emitted unescaped, so a value carrying a quote or a newline could author its own layer syntax. Every emit site now goes through the escapers. The tests assert the right property — not that the payload is absent (it legitimately survives inside the escaped literal) but that no payload becomes its own line of layer syntax. **Client** — `Opc.Ua.OpenUsd.Client` streams live values into an `IUsdSink`. `CompositeUsdSink` fans out to several sinks; the file sink interpolates between server samples so motion is continuous rather than stepped at the publishing interval. **Connector** — `tools/Opc.Ua.OpenUsd.Connector` composes a stage from a live server. The optional in-process viewport lives in a separate assembly probed at run time, so the connector still runs — and says why — when it is absent. - **Fix**: the asset cache and PKI root moved off the shared temp directory to `LocalApplicationData`. **Sample** — `PumpDeviceIntegrationServer` gains an OpenUSD representation of the pump. ## Notes for the reviewer - The viewport assembly is net10.0-only. It is what exercises the `Directory.Build.targets` change from 1/5: without it, the `net8.0` leg of the per-TFM CI build fails with `CS0433` because the `System.Threading.Lock` polyfill collides with the real type. - `UsdAssetDelivery` hashes through `SHA256.Create` rather than the static `HashData`, which does not exist on the net472/net48 targets this test project also builds for. ## Validation `dotnet build UA.slnx` — 0 errors, 0 warnings. | Suite | Result | | --- | --- | | Opc.Ua.OpenUsd.Tests | 621 / 0 | | Opc.Ua.Di.Tests | 321 / 0 | --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 8cbb8cd0-f0cb-4ab0-bea2-6202fbf69485
