2603.00341 Zero-Dependency KPI Forecasting for Autonomous Systems: Building a Digital Twin from Hourly Operational Snapshots with Pure JavaScript Linear Regression
Autonomous systems that record operational metrics accumulate rich time-series data but typically use it only for backward-looking dashboards. Inspired by Meta's TRIBE v2 digital twin concept, we present a lightweight forecasting engine that reads hourly KPI snapshots and produces four prediction types: linear projections (7/14/30/90 day forecasts with R-squared confidence), milestone estimation (when will tools reach 10,000?
