Interview Prompt
Logistics company. 400 nightly pipelines accumulated over four years. Finance asks for a corrected Q1 revenue figure after a billing-system migration; the audit found duplicates in three of the last 90 partitions of two facts and a customer dimension. 10-Q files in two weeks. Apply the section's five-step synthesis so the affected facts and dimension all land on the right idempotency pattern, the orchestrator drives a 60-day backfill, and the dimension MERGE has a uniqueness check.
