Name what can move

  • • Data, label, concept, pipeline, vendor-model and usage drift
  • • Quality and fairness by group, with and without labels
  • • Groundedness and refusals by topic and language for generative systems

Threshold, owner, consequence

  • • Every signal has a threshold, a window and an owner who can be paged
  • • A breach opens an issue, schedules a retrain or switches a degraded mode
  • • A severe breach opens an incident or trips the breaker

Evidence, not a chart

  • • Each check writes an evidence record, pass or fail
  • • The monitoring plan is data, and a threshold change is a reviewed diff
