A commodity audit trail is the time-ordered chain of every decision touching a commodity exposure: who reviewed the forward curve, who simulated which scenarios, who approved which fixing, when each step happened, and what changed in between. The trail is to commodity procurement what a transaction log is to a database — the system of record that makes everything else verifiable.
The need is non-negotiable in two contexts. The first is internal: a CFO who has just absorbed a commodity-driven margin compression wants to know which decisions led there and which alternatives were considered. The second is external: increasingly, regulation (EUDR, supplier sustainability standards, financial reporting frameworks) demands traceable evidence of commodity sourcing and risk-management practice. Both readers want the same thing — a chain, not a story.
INAYA generates the commodity audit trail automatically as decisions happen. Every fixing simulation, every approval, every override is logged with timestamp, inputs, and rationale. The trail is queryable by commodity, by SKU, by time window, by decision-maker. It is the spine that connects Market Foresight, Product Composer, and Decision Governance into one defensible system.
