Rowva Generic ERP Canonical Handoff

This is an implementation-ready canonical handoff and not a one-click import claim for an unnamed ERP. Open GENERIC_ERP_MAPPING.xlsx first to review the source-to-Rowva mapping, destination placeholders, stable data dictionary, relationship keys, validation summary, and exact import sequence.

Recommended import sequence:
- vendor

Use the root CSV/XLSX files as canonical import data after destination columns are approved. Review readiness_manifest.json and mapping_manifest.json before loading any destination system.
