init: scaffold Junction multi-protocol machine monitor (M1 walking skeleton)
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.
