sharepoint-must-materialize-to-snowflake-upstream

SharePoint CSV/Excel ingestion must NOT be handled inside R-Same. Any attempt to add file-polling or Graph API calls to the BI platform violates AR-4 (no ETL). The correct pattern is an upstream shim (Fivetran connector or n8n workflow) that writes SharePoint data to a SHAREPOINT_RAW schema in Snowflake, after which R-Same queries it like any other Snowflake table.
