Scenario: Metastability Bug: Reports & Metrics

Reports and metrics

Reports & Metrics for Scenario: Metastability Bug focuses on root-cause depth, containment plan clarity, debug sequencing. The goal is to convert issue observations into mechanism-backed closure decisions.

Reports must explain risk movement in root-cause depth, containment plan clarity, debug sequencing, not just issue counts. A report is complete only when ownership and closure action are explicit.

Metric focus: root-cause depth, containment plan clarity, debug sequencing

• Track root-cause depth, containment plan clarity, debug sequencing by block, mode, and severity.

• Separate structural warnings from behavior-proven hazards.

• Show waiver age and owner SLA alongside raw counts.

• Store evidence links with each closure claim.

Scenario debrief

Score each response on mechanism clarity, evidence quality, and signoff decision discipline.

Debrief prompts

1. Which crossing class or reset dependency failed first?

2. What evidence changed your decision?

3. Fix, waive, or escalate and why?

Key takeaways

• State crossing class, assumptions, and owner with every issue.

• Run structural and dynamic regressions after each fix.

Common pitfalls

• Treating all warnings as equivalent risk.

• Waiving issues without containment evidence.

• Skipping reset and reconvergence stress after CDC fixes.
