Internal invoice field extraction policy. Apply it exactly; the rules are company-specific and override general intuition.

ZetaCorp Internal Invoice Extraction Policy

Extract invoice data into the following proprietary fields. Follow the strict formatting conventions below.

Fields

• z_chronon: The invoice date converted to a 7-digit string in YYYYDDD format (Year + 3-digit zero-padded day of the year). Assume non-leap years for 2022/2023, leap year for 2024. Example: 'January 5, 2023' -> '2023005'.
• z_copper_val: The total amount due, converted to an integer representing the value in cents. Example: '$10.50' -> 1050, '45 dollars' -> 4500.
• z_tier_class: A tier designation based strictly on z_copper_val.
• If z_copper_val < 1000, use 'T-1'.
• If 1000 <= z_copper_val <= 5000, use 'T-2'.
• If z_copper_val > 5000, use 'T-3'.
• z_vendor_mode: An enum remapping the type of product/service provided.
• If 'services', 'consulting', or 'labor', output 'V_ALPHA'.
• If 'goods', 'hardware', or 'materials', output 'V_BETA'.
• If 'software', 'cloud', or 'SaaS', output 'V_GAMMA'.
• For anything else (e.g., food, utilities, rent), output 'V_DELTA'.
• z_ref_tag: The invoice or reference number. Must be entirely uppercase. If the original string does not begin with 'INV-', prepend 'INV-' to it. Example: '102a' -> 'INV-102A', 'INV-992' -> 'INV-992'.
