Reports and artifacts

• mock interview rubric

• scenario response score

• evidence completeness

• regression-plan quality

Mini case study

Candidate fixed the symptom but failed to define a regression matrix and ownership map.

Debug branches

• Name first failing boundary

• State one proving artifact

• Propose one bounded reversible fix

Senior review question

Ask: what boundary condition proves this topic is actually closed?
