Shortage Impact Map

Purpose

Deterministically explode the shortage: net the short part's usable on-hand and the incoming (late) PO against every open order that consumes it, and produce a per-order impact row (product, line, order, need-by, quantity at risk, status) plus a rolled-up impact summary (worst severity + the first-impact date). This is the mapping the whole packet turns on.

When to use

• After supply-knowledge-retrieve, in every run.
• "Which lines and orders does this shortage hit, and when does it bite?".

Inputs

• The contract payload with supply{} (on_hand, on_order, safety_stock), promised_date, revised_date and retrieved.open_orders[] (contract mfg.supplier-disruption.v1).
