Leverage a tiered architecture

Leverage a tiered architecture (such as Medallion) to progressively structure and refine unstructured data, extracting meaningful insights for decision-making

The issue proposes a tiered architecture such as Medallion for progressively structuring unstructured data, but names no files, entry points, datasets, or tests. Start by locating the platform's current data-ingestion and transformation structure, then clarify the intended tiers, inputs, outputs, and measurable definition of done before implementing.
