The v3.0 dual-namespace rewrite (PR #472) moved anchors and reshaped the build, so the plan is refreshed to stay executable: CPM correction (OtOpcUa is on Central Package Management, not inline versions), OpcUaClient options in .Contracts + GalaxyDriverBrowser in .Browser, DriverHostActor line shifts, and appsettings/owner precision. Driver-secret flow itself was untouched by v3.0, so the two-layer approach holds.
