r-dash-single-snowflake-connector-zero-ingestion

R-Dash connects to Snowflake only as its sole data source. All upstream systems (Salesforce, SAP S/4, SharePoint CSV/Excel) are materialized into Snowflake via external pipelines (Fivetran, n8n, custom shims) before Vantage queries them. AR-4 is absolute: zero ingestion, zero parsing, zero polling code inside R-Dash itself. Attempting to add direct SharePoint/Salesforce connectors violates this architectural invariant.
