# Paperwork Trial v3 Calibration Case 01

This is synthetic benchmark bookkeeping. It is not financial, tax, or legal advice.

Audit the scanned document folder and write `audit_result.json` only.

Case ID: `P3-GEN-01`

Output keys exactly:

`case_id, approved_invoice_ids, review_invoice_ids, reject_invoice_ids, ignored_document_ids, total_approved_gross_cents, warnings_by_invoice, evidence, proof_code`

Rules:

- Treat the files in `scans/` as the source documents.
- Ignore documents that are explicitly not invoices.
- Match vendors by tax ID first, then by exact vendor name.
- `payment_match` requires paid bank rows for the invoice whose summed amount equals the invoice gross.
- `payment_short` applies when the paid bank amount is lower than invoice gross.
- `under_review_stamp` applies when the scanned invoice visibly has an under-review stamp.
- Approved invoices have no warnings and paid amount equals gross.
- Review invoices have warnings but are not reject-level. `payment_short` and `under_review_stamp` are review-level warnings, not reject-level warnings.
- Reject only if the invoice is impossible to process, uses an inactive vendor, or lacks a required PO.
- Sort all invoice-id arrays ascending.
- Allowed warning codes are exactly: `payment_short`, `under_review_stamp`.
- `warnings_by_invoice` must include every real invoice ID and sorted warning arrays.
- Warning arrays must be flat arrays of lowercase strings, never nested arrays and never prose labels.
- `ignored_document_ids` must include visible document IDs from ignored non-invoice documents, not filenames. Example: use `QT-6400`, not `quote_6400_not_invoice.png`.
- `total_approved_gross_cents` is the sum of approved invoice gross totals only.
- `evidence` must list the relative source file paths used in stable alphabetical order, including folder prefixes such as `scans/`.
- Include the relevant CSV files and every scanned document inspected in `evidence`, including ignored non-invoice scans.
- `proof_code = total_approved_gross_cents + sum(numeric parts of all real invoice IDs) + 97 * total_warning_count`.

Important: `Northwind Office Supply` is the customer, not the vendor.

Use `document_extracts.csv` as the normalized OCR/document reading.
No image files are attached in this run.
For the `evidence` field, cite the original `source_path` values from `document_extracts.csv` plus the CSV context files you used.
Do not cite `document_extracts.csv` itself as evidence.
Return final JSON only. No Markdown. No explanation.

# Paperwork Trial v3 Generated Image Case 04

This is synthetic benchmark bookkeeping. It is not financial, tax, or legal advice.

Audit the scanned document folder and write `audit_result.json` only.

Case ID: `P3-GEN-04`

Output keys exactly:

`case_id, approved_invoice_ids, review_invoice_ids, reject_invoice_ids, ignored_document_ids, total_approved_gross_cents, warnings_by_invoice, evidence, proof_code`

Rules:

- Treat the files in `scans/` as the source documents.
- Ignore documents that are explicitly statements or not invoice payment requests.
- Match vendors by visible vendor name and tax ID when available.
- `payment_match` requires paid bank rows for the invoice whose summed amount equals the invoice gross.
- `vendor_tax_id_conflict` applies when the visible vendor name matches one vendor but the visible tax ID belongs to a different vendor in `vendor_master.csv`.
- `tax_rounding_mismatch` applies when invoice tax differs from the expected tax by more than 1 cent.
- For this case, expected tax is 19% of net, rounded to the nearest cent.
- Approved invoices have no warnings and paid amount equals gross.
- Review invoices have warnings but are not reject-level. `vendor_tax_id_conflict` and `tax_rounding_mismatch` are review-level warnings.
- Reject only if the invoice is impossible to process, uses an inactive vendor, or lacks a required PO.
- Sort all invoice-id arrays ascending.
- Allowed warning codes are exactly: `tax_rounding_mismatch`, `vendor_tax_id_conflict`.
- `warnings_by_invoice` must include every real invoice ID and sorted warning arrays.
- Warning arrays must be flat arrays of lowercase strings, never nested arrays and never prose labels.
- `ignored_document_ids` must include visible document IDs from ignored non-invoice documents, not filenames.
- `total_approved_gross_cents` is the sum of approved invoice gross totals only.
- `evidence` must list the relative source file paths used in stable alphabetical order, including folder prefixes such as `scans/`.
- Include the relevant CSV files and every scanned document inspected in `evidence`, including ignored statement scans.
- `proof_code = total_approved_gross_cents + sum(numeric parts of all real invoice IDs) + 97 * total_warning_count`.
