vantage-snowflake-only-single-source-architecture

Runwal Vantage consumes only Snowflake as its data source. All upstream sources (Salesforce, SAP S/4, SharePoint CSV/Excel) are pre-materialized into Snowflake via Fivetran/n8n/custom shims before Vantage touches them. Zero ingestion, polling, or file parsing code lives inside Vantage — this is AR-4 (absolute anti-requirement). Building any file-ingest or API-pull connector inside Vantage violates the architecture boundary.
