Anyone can extract. The question is whether it is right

pdftotext -layout statement.pdf - > statement.txt
python3 scripts/statement.py parse  statement.txt --out rows.csv
python3 scripts/statement.py verify rows.csv --opening 1240.55 --closing 2103.11

rows                7 (7 carry a balance)
chain checks        6
chain breaks        0
sum of movements    862.56
opening + movements 2103.11
stated closing      2103.11
difference          0.00

VERIFIED: the parse reproduces the statement exactly.

Every running balance must equal the previous balance plus the movement. That is not a convention, it is what a balance is. So the parse either reproduces the chain from the opening balance to the closing balance, or it is wrong and the chain says which row.

Change one digit and:

NOT VERIFIED: the parse does not reproduce the statement.

  break at row 1, 2026-06-03  PAGAMENTO POS SUPERMERCATO
    2740.55 -8.24 should give 2732.31, the statement says 2658.15 (off by -74.16)
    hint: the difference equals the amount on 2026-06-05: that row is probably
          duplicated or missing

Two decisions made once, never per row

`01/06` is ambiguous and no cleverness resolves a single row: if any date in the file has a first component above 12, the whole document is day-first. Deciding per row silently sw
