*
* @title CIA Schema Validator - Data Quality Assurance Engine
*
* @description
* **INTELLIGENCE OPERATIVE PERSPECTIVE**
*
* This module serves as the critical data validation gate in the political intelligence platform,
* ensuring all CIA platform exports conform to their expected JSON schemas. Operating at the
* intersection of data integrity and threat detection, the schema validator prevents corrupted,
* tampered, or malformed data from reaching the analytical intelligence pipeline.
*
* **OPERATIONAL ARCHITECTURE:**
* The validator employs Ajv 2019 specification with strict error reporting to validate:
* - Parliamentary voting records (voteringar) - integrity critical for vote analysis
* - Member records (ledamöter) - baseline data for behavioral analysis
* - Document metadata (dokument) - chain of custody for legislative documents
* - Committee records (betänkanden) - organizational structure validation
* - Government documents (regering) - executive branch intelligence
*
* **INTELLIGENCE APPLICATIONS:**
* 1. Anomaly Detection: Schema violations trigger investigation protocols - may indicate
* data tampering, system compromise, or source reliability degradation
* 2. Data Provenance: Schema conformance provides baseline assurance for data authenticity
* 3. Pipeline Integrity: Early validation prevents corrupted data from polluting analytical
* downstream (news generation, dashboard updates, trend analysis)
* 4. Incident Response: Failed validations log detailed error chains for forensic analysis
*
* **SECURITY & COMPLIANCE:**
* - JSON Schema validation prevents injection attacks on structured data
* - Verbose error reporting supports compliance auditing (ISO 27001, GDPR)
* - Type validation ensures downstream code security (no unexpected object shapes)
* - Automatic schema updates detect when CIA platform structure evolves
*
* **OPERATIONAL NOTES:**
* - Runs pre-build as quality gate in CI/CD pipeline
* - Provides detailed error messages for debugging data integration issues
* - Supports both single-file and batch validation modes
* - Exit code 1 blocks deployment if critical data is corrupted
*
* @usage
* ```
* npm run validate-schemas # Validate all exports
* node scripts/validate-against-cia-schemas.js produktnavn # Validate one export
* ```
*
* @performance
* - Validation latency: ~50ms per export file
* - Memory usage: ~10MB for schema compilation (reusable)
* - Recommended: Run on file change events during development
*
* @intelligence Risk Assessment Matrix
* - Critical: Schema violations in vote records (affects coalition analysis)
* - High: Member record corruption (impacts behavioral tracking)
* - Medium: Document metadata errors (non-breaking for some analysis)
* - Low: Minor field validation failures (caught downstream)
*
* @osint Data Source Verification
* - Validates export consistency against published CIA schema specifications
* - Detects when CIA platform introduces breaking changes
* - Enables early detection of data quality issues at source
*
* @risk Schema Drift Detection
* - Monitors for unauthorized schema modifications in CIA exports
* - Prevents data corruption from propagating through intelligence pipeline
* - Supports incident response for suspected data integrity breaches
*
* @gdpr Data Integrity Assurance
* - Ensures member personal data conforms to expected format
* - Validates data retention classifications are preserved
* - Supports audit trail for data processing compliance
*
* @security Input Validation Hardening
* - Prevents malformed JSON from reaching processing logic
* - Detects XSS/injection attempts in document fields
* - Validates schema constraints (string lengths, numeric ranges)
