Greenfield C# app reading industrial machine data over pluggable protocols. M1 walking skeleton: MTConnect plugin polls a machine, Avalonia dashboard shows live last datum. Build 0 warn/0 err on net48 + net8.0 (Linux), 115 unit tests + 2 docker-gated integration tests. Projects: - Junction.Domain (netstandard2.0): Result<T>, models, IProtocolDriver, IMachineRepository, plugin manifest. Zero package deps. - Junction.Core (netstandard2.0): PollingEngine, PluginLoader (Assembly.LoadFrom), MachineMonitor, DI extensions. - Junction.Persistence (netstandard2.0): SqliteMachineRepository (Dapper), schema, connection factory. Provider-swap seam to SQL Server. - Junction.Protocols.MTConnect (netstandard2.0): HTTP driver + namespace- version-agnostic parser (MTConnect 1.7 + 2.0). Runtime plugin. - Junction.App (net48;net8.0): Avalonia MVVM, live dashboard, NLog, DI root. - Junction.Tests (net8.0): xUnit + Moq, 117 tests. - mock/: docker-compose MTConnect agent (ladder99/agent). Target net48 for Windows 7/8 fleet compatibility. Avalonia pinned 11.3.x. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
