Definition
The trustworthiness of alerts, metrics, and reports used to govern a system.
High signal credibility pairs transparent sampling, explainability for accountability, and human testimony so warnings trigger action instead of alert fatigue or dismissal.
Targets & breach behavior. Measurement window: weekly precision/recall review; monthly audit. Target / floor / ceiling: target ≥ 0.85 precision, floor ≥ 0.70, ceiling false-positive rate ≥ 0.40. Owner: traceable ownership (required). Breach action: halt dependent automation, recalibrate models, or require human confirmation. Public surface: published signal health via receipt, time transparency, and decision artifacts.
