POA Interpretation

Summary

POA interpretation turns document evidence into typed AP document facts that can be validated, matched, reviewed, and persisted.

Problem

OCR and LLM output is probabilistic. Treating it as final truth would push mistakes into accounting and procurement systems.

Principle

Normalize AI-assisted interpretation into typed results, attach attempt evidence, and route uncertainty to review.

Platform Shape

Document runtime orchestrates processing attempts. Interpretation services and contracts validate extracted headers, lines, vendors, jobs, PO references, and document type decisions before persistence and matching proceed.
