UCP 600 / ISBP 745 Document Examination Assembler

Recomputes the letter-of-credit document examination a checker already works from a paper checklist inside the 5-banking-day window, using structured field values the checker transcribes off the presentation. Checks presentation timing against the credit's expiry and the Art. 14(c) shipment-plus-window rule, the Art. 14(b) examination-window arithmetic, Art. 30 quantity and amount tolerances, the Art. 28(f)(ii) insurance floor, cross-document consistency under Art. 14(d)/(e), and draft tenor arithmetic. Every finding cites its article number.

What this does not do

It does not read, upload, or parse any document image, PDF, or scan; every field is a value the checker has already transcribed. It does not itself determine that a presentation is complying under UCP 600; a DISCREPANT verdict is a citable record of the arithmetic checks this tool ran, which the examiner and, on referral, the issuing bank evaluate against the full presentation. Goods-description conformity across documents is a checker judgment declared as a boolean input, never inferred from free text.

ART-420 MT700 LC Field Validator validates the SWIFT MT700 issuance message itself, the fields the credit is opened with. This node is the downstream examination step: once documents are presented against an already-issued credit, it recomputes the checker's own arithmetic (timing, tolerances, insurance floor, cross-document consistency, draft tenor) rather than re-validating the issuance message.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `examine_lc_document_presentation`. Task: Recompute the letter-of-credit document examination a checker already works from a paper checklist inside the 5-banking-day window, from structured fields the checker has transcribed off the presentation -- no OCR, no document upload, no parsing of any document image or free text.
Call it with arguments: {"policy_parameters":{"lc":{"amount_minor":5000000,"quantity":{"value":1000,"unit":"MT"},"expiry_date":"2026-07-31","latest_shipment_date":"2026-06-30","named_ports":{"loading":"Shanghai","discharge":"Rotterdam"},"insurance_required":true},"presentation_date":"2026-06-20","examination_date":"2026-06-24","documents":{"invoice":{"amount_minor":5000000,"quantity":{"value":1000,"unit":"MT"},"goods_description":"Widgets, 1000 MT"},"transport_doc":{"shipment_date":"2026-06-15","port_of_loading":"Shanghai","port_of_discharge":"Rotterdam"},"insurance":{"amount_minor":5500000,"cif_cip_value_minor":5000000,"effective_date":"2026-06-15"},"drafts":[{"tenor_type":"sight","amount_minor":5000000,"drawee":"Buyer Bank plc"}]},"goods_description_conforms":{"invoice_vs_transport":true}}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
