DATMEX's scanned bills are in the ILUZ/IAGUA/IPREDIAL/ITEL invoice-image OLE
columns (typed ELECTRIC_BILL/WATER_BILL/PROPERTY_TAX_BILL/PHONE_BILL), not
doc_1/doc_2 (which are empty). Add them to the extractor with meaningful
document types.
Data finding: the LONGBINARY columns are almost entirely unpopulated — only 3
DATMEX blob cells across 1520 rows, and 67 policy blobs (MULT/TABLA AUTOS
AMPL foto/docs). The large .accdb/.mdb file sizes are Access bloat, not
documents. Final: 70 documents in MinIO (~290 MB), 3 service_documents +
67 policy_documents, 0 orphans, storageKeys resolve.
Migration steps 1-4 (staging, reconciliation, transform+load, documents) are
complete; RESUME.md updated. Next: the Customer module (API/web).
