Module database_validator 

Compile-time database validation for schema definitions.

Validates a compiled schema against a live database at three levels:

• L1: sql_source relation exists in the database
• L2: Columns and JSON column types match
• L3: JSONB keys exist in sampled rows (best-effort)

Each finding carries a Severity: error-severity drift (a relation that does not exist, a required field’s key absent from every sampled row) fails compile --database unless --allow-drift is passed (#384); warn-severity findings are always advisory.
