POA Matching And Validation

Summary

Matching and validation decide whether interpreted document facts line up with purchase orders, receipts, jobs, vendors, and routing policy.

Problem

An interpreted invoice or packing slip can still be operationally wrong. The system must verify relationships before it creates external commands.

Principle

Use deterministic validation and typed matching results before review or side effects.

Platform Shape

POA matching services, matching contracts, policy modules, and lookup services compose the validation layer. When matching is uncertain, the workflow creates review or repair state instead of forcing a best guess.
