Linley Hoang (Engineering Manager):
“Excellent partitioning approach by day. The SCQA problem framing clearly communicated why the runaway queries originated in warehouse tier 4.”
Isabella Garcia (Security Officer):
“Audited query against GDPR/NDPA rules. Zero customer PII was exposed in the unnested diagnostic logs. Passed.”
The 3-Step Simulation Loop
