Prompt

Audit the synthetic remittance split intake folder in `incoming/`.

Write these files:
- `work/attachment_index.json`
- `work/final_document_set.json`
- `work/normalized/INV-3301.txt`
- `work/normalized/INV-3302.txt`
- `audit_result.json`
- `proof.txt`

Use `incoming/README_TASK.md` as the full task specification. Use the generated image attachments, the AP note, bank exports, vendor master, and purchase orders.

Important:
- Identify the active bank export and ignore the draft export.
- Use remittance advice RA-771 to split the single bank payment across two final invoices.
- Do not treat the proforma estimate as an invoice.
- Do not modify anything under `incoming/`.
- This is benchmark bookkeeping, not financial, tax, or legal advice.
- `proof.txt` must contain only the numeric proof code.

# Paperwork Workflow Case 06: Remittance Split

Audit this synthetic intake folder. This is benchmark bookkeeping, not financial or tax advice.

You must not modify anything under incoming/.

Case ID for audit_result.json: P3-WORK-06

Steps:
1. Identify active source files and ignore drafts, old exports, and non-invoice distractors.
2. Use the remittance advice to map the single bank payment to the final invoices.
3. Create work/attachment_index.json.
4. Create work/final_document_set.json.
5. Create normalized invoice text files under work/normalized/.
6. Create audit_result.json.
7. Create proof.txt containing only the final proof_code.

Required audit_result.json keys:
case_id, approved_invoice_ids, review_invoice_ids, reject_invoice_ids,
ignored_document_ids, total_approved_gross_cents, warnings_by_invoice,
evidence, proof_code

Required audit_result.json values and formats:
- case_id must be "P3-WORK-06"
- ignored_document_ids must be ["PRO-3303"]
- warnings_by_invoice must use short warning codes only, not prose sentences
- evidence must be an array of source path strings, not a nested object

Proof code formula:
total_approved_gross_cents
+ numeric parts of approved/review/reject invoice IDs
+ numeric part of the active remittance batch
+ 97 * total warning count

Use invoice IDs only for approved/review/reject invoice IDs. Do not include proforma or remittance document IDs in the invoice-ID sum.

Required work/attachment_index.json shape:
{"attachments":[{"attachment_path":"...","document_id":"...","document_type":"...","use":"..."}]}

Required work/final_document_set.json shape:
{
  "active_bank_export": "...",
  "active_remittance_batch": "...",
  "final_invoice_ids": [...],
  "ignored_document_ids": [...],
  "ignored_source_files": [...],
  "payment_allocations": [{"invoice_id":"...","gross_total_cents":123}]
}

AP intake note, May batch:
- Use bank_export_final.csv, not bank_export_draft.csv.
- Vendor Bright Coast Office Supplies is active.
- Remittance advice RA-771 explains payment BATCH-771.
- The proforma is a quote-style document and should not be treated as an invoice.
