GRITWORKS INSURANCE EVALUATION PACK - REVIEW COPY

One connected fictional US health-insurance case: AVERY MORGAN / GW-IN-04217.
Five document types: premium statement, CMS-1500 claim, itemized invoice,
explanation of benefits (2 pages), and final patient balance statement.
This is a health-insurance pack, not a cross-section of all insurance lines.

CONNECTED CASE
$600 billed - $200 contractual reduction = $400 allowed.
$400 allowed - $326 insurer payment = $74 patient responsibility.
$74 responsibility - $30 already paid at the visit = $44 balance due.
The invoice predates adjudication: $570 pending after the deposit is NOT the final
patient balance. April premium $460 is separate from claim cost sharing.
Service 04/15/2026; invoice 04/16; adjudication 04/22; patient statement 04/24.
Annual deductible was already met; office visit $30 copay; labs 20% coinsurance.
All charges, coverage terms, entities, addresses and identifiers are illustrative.

JSON AND ANNOTATIONS
<stem>.json: normalized expected answers.
<stem>.boxes.json: field-level rectangles in PDF points, top-left origin.
<stem>_bbox.json: normalized vertices and pixel boxes at 96 DPI.
Clean annotated PDFs in the full pack show rectangles; click for field key/value.
Boxes cover selected populated case fields, not every printed word. Clean word
boxes are recorded from the text authored before rasterization; variants omit
word boxes. No OCR confidence is asserted. Static form labels are not annotated.
For clean raster PDFs the body has no hidden answer text; their disclosure footer
remains text. Negative PDFs are entirely image-only, including the disclosure.
Use JSON/annotated files as ground truth, not extraction inputs.

GEOMETRY
Perspective, skew and crop fields are projected using the supplied homography.
Variant rectangles are clipped to page bounds; projected polygons can extend
outside the page. Visibility means geometric clipping, not OCR readability.
Expected answers retain the original value even when partly cropped/obscured.
Photometric changes keep coordinates unchanged. All variants use identical data.

PROVENANCE / REVIEW STATUS
Adapted from the supplied templates. These are synthetic review samples, not
issued medical/insurance records or verified GritRender exports. Original source
files remain unchanged. The website has not been updated. Review before publication.

CONTENTS: Exactly 10 input PDFs (12 pages): 5 clean + 5 negative.
Premium photocopy; CMS-1500 strong blur; invoice coffee stain; EOB low light;
patient statement crop. 30 matching JSON files plus pack-level metadata.
Annotated PDFs and other capture variants are in the separate complete archive.
