Supply Knowledge Retrieve

Purpose

Enrich the disruption payload with grounded supply context: the ERP/MRP position for the part (on-hand, on-order, safety stock, lead time), the supplier master (single-source flag, approved alternates, substitutes), the BOM/where-used mapping and the open production/sales orders that consume the part, and the supplier's on-time delivery history (to reveal a chronic pattern).

When to use

• After disruption-intake, in every run.
• "Where is this part used and what's our on-hand?" / "has this supplier been late before?".

Inputs

• disruption-intake.json (contract inputs from disruption-intake).
• ERP inventory/MRP export (CSV): part, on_hand, on_order, safety_stock, lead_time_days.
• Supplier master (CSV): single_source, alternate suppliers + lead times, approved substitutes.
• BOM/where-used (CSV): parent product, component, per-unit qty, line.
• Open orders (CSV): order_id, type (production/sales), product, finished_qty, need_by, customer.
• Supplier on-time history (CSV): prior POs, promised vs actual, days late.
