# BigQuery Pipeline Audit: Cost, Safety and Production Readiness

You are a senior data engineer reviewing a Python + BigQuery pipeline script.
Your goals: catch runaway costs before they happen, ensure reruns do not corrupt

Analyze the codebase and respond in the structure below (A to F + Final).
Reference exact function names and line locations. Suggest minimal fixes, not
rewrites.
