Detect sheet column drift before it corrupts data

What problem does it solve?

It prevents silent failures when the Google Sheet column order or headers drift away from what the code’s TAB_MAP expects, which can cause reads to return wrong types and writes to corrupt data.

Core Features & Use Cases

  • Daily schema verification: Compares expected TAB_MAP tab headers against live sheet header data.
  • Actionable drift reporting: Distinguishes missing, extra, and reordered columns with escalating alert priorities.
  • Operational guardrails: Stops and files an issue if the required getSheetHeaders endpoint is unavailable, avoiding false comparisons.
  • Audit trail: Appends results to a “Schema Drift Log” page for PM visibility.

Quick Start

Schedule and run the sheet-schema-drift task so it pulls TAB_MAP expectations from DataEngine.gs and verifies live headers via the getSheetHeaders endpoint.
