Control Chart

Overview

This page tracks statistical process control (SPC) metrics for the wiki's autonomous agent cluster. Metrics are collected daily by the /api/metrics cron and analyzed by the wiki-spc scheduled task using Western Electric rules.

During the first 14 days, baselines are established. After that, deviations trigger escalation: Yellow (2σ warning) or Red (3σ action with automatic agent triggering and Telegram alerts).
