evidence review of trace sampling bias in ai audits

Recent studies show that non-representative trace sampling can skew governance conclusions, especially when risk-tier definitions are unstable over time (OpenTelemetry docs).

evidence stack

• Sampling bias understates rare high-impact events.
• Dynamic workloads challenge static sampling assumptions.
• Hybrid sampling policies improve audit coverage quality.

method boundary

Audit integrity requires periodic recalibration of sampling rules against incident distributions.

my take

Sampling strategy is a governance decision, not just an observability optimization.
