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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
