# Description Add a generic, company-neutral recycling simulation sample and reusable plastics/rubber companion-model packages. One durable causal coordinator and ten separately launched OPC UA process views provide deterministic material balances, finite buffers, genealogy, utilities, quality holds/disposition, authenticated controls and crash recovery. Process views consume committed state instead of running independent simulations. Real companion-model equipment instances use DI/Machinery/AMB discovery, Machine Vision, Pumps/Scales, granulate drying, extrusion, filtration and pelletizing. Vendor/process extensions remain sample-local. Connectors and WoT conversion are out of scope. **External source-contract parity and complete deployment qualification are not claimed complete.** The sample and managed tests target **.NET 8, 9 and 10**. The consolidated [recycling guide](samples/Recycling/README.md) explains the actual composition, simulation, observation paths and exposed data; the application-directory README points to that guide. Typed client member extensions are emitted at build time through the default-false `ModelSourceGeneratorClientAccessorsOnly` opt-in. Extrusion uses it for all twelve parts instead of checked-in generated C# and a Python generator. The shared client runtime retains typed values, quality, timestamps and streaming behavior. ### Package layout Six packages contain fourteen models in two model-producing assemblies: | Specifications | Model | Typed client | Server runtime | | --- | --- | --- | --- | | OPC 40083 and OPC 40082-6 | `Opc.Ua.PlasticsRubber` | `Opc.Ua.PlasticsRubber.Client` | `Opc.Ua.PlasticsRubber.Server` | | OPC 40084 parts 1–12 | `Opc.Ua.Extrusion` | `Opc.Ua.Extrusion.Client` | `Opc.Ua.Extrusion.Server` | NuGet IDs use the `OPCFoundation.NetStandard.` prefix. All six packages are registered in `.azurepipelines/expected-packages.txt` and the generated preview-pack solution. Granulate-drying code lives in `GranulateDrying` folders in the PlasticsRubber projects; extrusion uses per-part folders. There are no standalone granulate-drying or per-part extrusion packages. Published model identities and CLR namespaces remain distinct and unchanged. The common 1.03 interface is independently authored on the explicitly MIT-licensed 1.02 implementation basis; the official 1.03 XML is not redistributed. The other imported models retain their individual MIT notices. All 42 pinned model, identifier and basis files retain their manifest-backed bytes, including their staged Git blobs. No formal companion certification is claimed; the disputed Filter profile is not advertised. ## Related Issues No tracking issue is currently linked. ## Checklist _Put an `x` in the boxes that apply.
