# Launcher Next target architecture

Launcher Next is a parallel .NET 8 foundation: one visible x64 application, immutable versioned local packages, manifest/hash validation, atomic activation, rollback pointer, explicit dry-run Plant launch preparation and structured local logs. It does not deploy, alter profiles, start AutoCAD or change legacy files in this foundation.

```text
Launcher.Next.App -> Application orchestration -> Infrastructure adapters
  -> product discovery (registry abstraction)
  -> package catalog / local synchronizer / versioned store
  -> manifest validation / SHA-256
  -> startup script builder -> Process launcher dry-run
```

For P_Rec_Annot, one local entry `PRecAnnot.Plant3D2026.dll` replaces legacy `OrthoLoader -> Settings.xml -> 20 NETLOAD` orchestration. Its internal dependencies are CLR dependencies; Autodesk assemblies remain supplied by AutoCAD.
