Supply Chains and Procurement
Reading supply signals that do not move together, and keeping estimates, reports and assumptions apart.
Architecture defined The data model, risks, controls and intended decisions are documented. No operating system is implied. Risk tier 2 / 4
Problem
Production, import, inventory and price signals can point in different directions, and procurement decisions need to know which signal is which.
Evaluation method
Claims are traced to public sources. Operational use would need current private data.
Human review
A procurement owner reviews any recommendation before it is acted on.
Decision authority
The buying organization decides. Delta Arc supplies evidence and framing.

Evidence in this domain
What the inventories-to-sales ratio tells procurement teams
The US inventories/sales ratio is a revisable, nominal, national aggregate: useful macro context, not a supplier or category signal.
A Monthly Drop Is Not an Easing
Retail beef prices fell in September and were still above last year. Both are true, and they answer different questions.
Where the evidence lives
14 primary sources, with what each can and cannot establish.
Proofs of concept in this domain
Examples, not limits. A reusable core does not replace domain validation. Each implementation needs its own sources, rules, controls, testing and qualified review for its intended use.
