Easy Summary
Corroborated manipulation indicators were detected: invoice amount math conflicts align with field-level replacement signals and revision markers.
Next step: Treat this PDF as likely manipulated. Verify the invoice total, subtotal, bill-to fields, and revision history before acceptance.

Running Balance Progression
Should be: Each row balance follows prior balance +/- debit/credit · Found in file: 221 row mismatch(es)
Transaction-level running balance continuity test.
Debit/credit Exclusivity
Should be: Each transaction row should primarily indicate debit or credit · Found in file: 266 ambiguous row(s)
Rows carrying both debit and credit values are unusual in standard statement exports.
Date Ordering Continuity
Should be: Chronological order · Found in file: 15 out-of-order rows
Date sequence inconsistency may indicate row insertion/reordering.
Duplicate Transaction References
Should be: Minimal duplicate references · Found in file: 1 duplicate reference(s)
Repeated transaction reference values can be a notable anomaly.
Ocr Vs Embedded Text Layer Consistency
Should be: Visible/OCR text should largely align with embedded text layer · Found in file: similarity=0.15, ocrCriticalCoverage=0.90, embeddedTokens=1092, ocrTokens=180
OCR-visible content is broadly consistent with the embedded text layer.
Opening/closing balance reconciliation

Transaction row balance continuity
Should be: None · Found in file: None
No transaction rows were extracted.

Text Overlap
Multiple overlapping text boxes were detected. This pattern can be consistent with patch-style edits.
Footer Shift
Totals/signature/footer markers appear at inconsistent vertical zones across pages.
Field replacement detection
Advisory field-level typography/alignment inconsistencies were observed, but no structural/content manipulation evidence was detected.
Risk score20/100
Assessed fields4
Closing Balance
Possible field replacement: field typography differs from nearby text; field text spacing is irregular versus surrounding typography; field text has unusual intra-value spacing.
Account Number
Possible field replacement: multiple variants of this critical field appear across pages; account number format is inconsistent with typical statement patterns; hard evidence is limited to one structural/content rule layer and should be interpreted cautiously.
Opening Balance
Advisory field-level risk: field text spacing is irregular versus surrounding typography; field horizontal alignment diverges from peer rows. This is not treated as manipulation evidence unless supported by structural/content checks.
