Validation Checklist - Implementation Coverage

This document maps the 14 validation checklist items from Initial.md to their implementation in the codebase.

Checklist Items (from Initial.md lines 314-328)

Next Steps

  1. Create sample test workbook for manual validation
  2. Run end-to-end test with real workbook
  3. Verify all 76 fields extract correctly
  4. Confirm master file format matches template
  5. Test error handling with malformed workbook
  6. Verify deduplication works correctly
  7. Test full pipeline with multiple business units
