Key facts:

• SQL never executes without passing validate_sql_safety; the product exposes a read-only SQL preview with an explicit execution boundary ([[Problem and Solution]]).
• The executor is pro-customtools tier; generation is pro tier ([[Model Registry]]).
• Results feed generate_chart_spec for visual output, and the query is persisted to memory (save_query_to_memory) for later recall.
• Schema and query engine live in clinical_schemas.py and database.py ([[Module Reference]]).
