What to do

  1. Start with privacy and governance.
  2. Choose cases that represent important user behavior, high risk, new failure modes, or recurring regressions.
  3. Keep raw traces separate from sanitized eval cases.

Evidence to preserve

  • Preserve the inputs, versions, configurations, raw outcomes, and results for trace, production trace, production trace mining needed to reproduce work on Production Trace Mining.
  • Report results for trace, production trace, production trace mining by relevant slice, separate blocker failures from averages, state uncertainty and blind spots, and connect the result to a release decision.

Expert note

Production trace mining should track sampling frame, redaction method, cluster stability, label confidence, recurrence rate, severity, business impact, and whether promoted cases reduce future incident classes.
