feat: history & trends (v0.6)
Time-series history persisted + per-item trend sparklines in detail view.
Data (Domain+Persistence): HistoryPoint model; IMachineRepository +Append/
Get/Prune history; snapshot_history table (append-only) + index; DeleteAsync
cascades history. Port purity kept (Result/Cancelled, no throw).
Core: MachineMonitor.PersistAsync appends history on Connected snapshots +
throttled retention prune (7-day window, <=1/hour via Interlocked-CAS), never
blocks/undoes latest-snapshot save.
App: custom Sparkline Control (StreamGeometry polyline, min/max-scaled,
net48-safe, no charting dep); DataItemRowViewModel observable +Trend/HasTrend +
pure TryParseNumeric; MachineDetailViewModel loads per-item history (1h window,
60 pts) on load + each snapshot, parses numeric, sets Trend on UI thread;
detail view Trend column.
Projects: Domain, Persistence, Core, App, Tests (+31: 196 pass + 2 skip).

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.
