Basic Structural Markers

Should be: At least one date and one amount for financial docs · Found in file: dates=12, amounts=180

Missing dates or monetary values lowers confidence in structural coherence.

WARNING
Totals Marker Presence

Should be: Total markers appear in summary-capable docs · Found in file: 0 total marker(s)

Absence of total markers in a financial-looking document is flagged.

PASS
Ocr Vs Embedded Text Layer Consistency

Should be: Visible/OCR text should largely align with embedded text layer · Found in file: similarity=0.39, ocrCriticalCoverage=1.00, embeddedTokens=169, ocrTokens=83

OCR-visible content is broadly consistent with the embedded text layer.

PASS
