# Description Implement OPC UA Part 10 Programs across `Opc.Ua.Core`/`Core.Types`, `Opc.Ua.Server`, and `Opc.Ua.Client`, reusing the existing state-machine, source-generation, node-management, auditing, and streaming-subscription infrastructure. - Add asynchronous provider-backed execution, standard controls, internal/autonomous transitions, generation checks, and nested-state activation/resumption. - Add checked creation/adoption, vendor Create adapters, deletion, recycling and instance limits, auto-delete, DI, and direct-construction paths. - Maintain ProgramDiagnostic2 and retained final results; publish captured intermediate results and concrete transition/audit events with access controls. - Add generated SDK models/proxies, typed client discovery and reads, event streams, and subscribe-before-call readiness handling. - Add unit, connected client/server, generated Annex A-style model, and NativeAOT coverage. Document usage and migration in `docs/Programs.md` and related guides. ### Compatibility and design decisions The linked Part 10 document is v1.05.00; namespace-zero definitions remain aligned with 1.05.07. Documentation distinguishes normative requirements from conflicting specification text and SDK conventions. - Correct state numbers to Halted=11, Ready=12, Running=13, Suspended=14. Generated subtypes retain inherited namespace-zero state/transition identifiers. - Managed Reset is Halted-to-Ready only. Preserve the existing low-level Reset-from-Suspended behavior for compatibility. - Preserve UInt32 limit types; use `UInt32.MaxValue` as a documented SDK unlimited convention. RecycleCount overflow reports BadOutOfRange without stopping unlimited execution. - In-memory default with injectable providers. Durable recovery, distributed execution/failover, and a production Annex A download engine are excluded. ## Checklist _Put an `x` in the boxes that apply. You can complete these step by step after opening the PR._ - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. Tests and focused coverage evidence are above; the combined tests/coverage checkbox remains open because a whole-repository coverage increase has not been established. CLA status, CI/CodeQL results, tracking-issue approval, and PR feedback are not asserted.
