🔒 Schema-Only Context Protocol

Text-to-SQL Without Sending
Raw Data to OpenAI.

When teams build natural language query interfaces, the naive mistake is passing table contents over an API. VeilAnalytics separates schema context from data compute.

The Schema-Only Prompting Mechanism

Look at the exact difference between what traditional cloud tools send vs what VeilAnalytics transmits:

❌ Traditional Cloud AI Tools
Transmits entire CSV files, customer names, financial values, and raw rows across public APIs to cloud LLM servers.
✅ VeilAnalytics Architecture
Transmits ONLY column definitions: customer_id: INT, spend: FLOAT. Raw records never touch the network. 
-- What Runs 100% Client-Side on Your Hardware:
SELECT 
  customer_segment,
  ROUND(SUM(transaction_amount), 2) AS total_revenue
FROM read_parquet('financial_records.parquet')
WHERE status = 'settled'
GROUP BY customer_segment
ORDER BY total_revenue DESC;

SQL AST Sandbox & Safety Guardrails

Every AI-synthesized SQL query passes through an in-process AST (Abstract Syntax Tree) Validator before hitting the local DuckDB engine. Any destructive keywords (DROP, DELETE, UPDATE, INSERT, ALTER) or multi-statement injections are blocked client-side. Only safe, read-only SELECT queries can execute.
