Initial design explored a file-to-table materialisation shim inside R-Same to ingest SharePoint CSV/Excel directly. This was reverted: all upstream sources (Salesforce, SAP, SharePoint) land in Snowflake via existing pipelines (Fivetran/n8n), and R-Same consumes Snowflake only. AR-4 (no ETL/ELT in the platform) is therefore absolute with no exceptions. This eliminates an entire ingestion subsystem and halves connector complexity.
