The v1.0.0 head read a mortgage statement as Form 1098 at 0.86 because the
data had no account-statement classes, one template style and no hard
negatives. v1.1.0 adds 7,271 programmatically generated rows on top of the
unchanged v1.0.0 rows, label IDs and splits.
- 12 new fine labels (IDs 83-94) and 7 new families (IDs 42-48), including
MORTGAGE_STATEMENT, PAYSTUB, CONSOLIDATED_1099 and OTHER_TAX_FORM
- Realistic multi-layout rows for 49 existing labels: real IRS box labels,
title top/bottom/removed, OCR noise, compact snippets, raw CSV exports
- Hard negatives for statements that mention tax forms; UNKNOWN_DOCUMENT
broadened to 26 kinds
- Held-out layouts per label and held-out kinds for OTHER/UNKNOWN; zero
cross-split group, exact or digit-normalized leaks
- Header-masked v1.1 view, 130-text external probe set (dev and blind),
generator, TF-IDF baseline and frozen-MiniLM probe scripts and reports
