+# Document Intelligence
+
+An offline document-processing workload over a small synthetic procurement
+dataset. It ingests semi-structured text invoices, classifies them, extracts
+fields, reconciles totals, detects duplicate invoice numbers, and emits an
+auditable JSONL/CSV report. It uses only Python's standard library.
+
+Run `./run.sh`. The files in `data/documents/` are the versioned test dataset.
+Replace that directory with a larger local corpus to create a long-running run.
