* @name CIA Schema Synchronization - Upstream Schema Caching System
*
* @description
* Automated schema synchronization system fetching and caching all 19 JSON schemas
* from the CIA GitHub repository. Maintains local copies of data product schemas
* for validation, type generation, and data consistency verification. Enables offline
* operation and faster validation cycles compared to remote fetching.
*
* Strategic Purpose:
* Ensures riksdagsmonitor maintains synchronized copies of CIA platform's data
* product specifications, enabling validation of incoming data against authoritative
* schema definitions. Supports type-safe data handling through schema-driven code
* generation and provides audit trail of data compatibility versions.
*
* CIA Platform Integration:
* CIA (Continuous Intelligence Architecture) platform operates the Swedish parliament
* intelligence system, producing 19 data products with published JSON schemas. These
* schemas define data structure, validation rules, and semantic meaning for each
* intelligence product. riksdagsmonitor consumes these schemas for data validation.
*
* CIA Data Products (19 schemas):
* - Dashboards: overview-dashboard, cabinet-scorecard, election-analysis
* - Personnel Analysis: top10-influential-mps, top10-productive-mps, top10-controversial-mps,
* top10-absent-mps, top10-rebels, top10-coalition-brokers, top10-rising-stars,
* top10-electoral-risk, top10-ethics-concerns, top10-media-presence
* - Network Analysis: committee-network, politician-career
* - Longitudinal Data: party-longitudinal, riksdag-overview, ministry-performance
*
* Schema Synchronization Workflow:
* 1. Fetch schema list from CIA GitHub repository
* 2. For each schema:
* - Download raw JSON schema file from GitHub
* - Validate schema structure (JSON schema v4 compliance)
* - Compute SHA-256 checksum for integrity verification
* - Store in local ./schemas/cia/ directory
* 3. Update metadata with timestamps and checksums
* 4. Generate compatibility report
* 5. Log synchronization status and any errors
*
* Remote Data Source:
* - Repository: https://github.com/Hack23/cia
* - Schema Base URL: https://raw.githubusercontent.com/Hack23/cia/master/json-export-specs/schemas/
* - File Naming: {schema-name}.json (e.g., overview-dashboard.json)
* - License: Apache-2.0 (compatible with riksdagsmonitor)
* - Access: No authentication required (public repository)
*
* Local Cache Structure:
* - Root: ./schemas/cia/
* - Schema files: {schema-name}.json (19 files)
* - Metadata directory: ./schemas/metadata/
* - Metadata file: cia-schemas-metadata.json
*
* Metadata Management:
* Maintains JSON file tracking:
* - File checksums: SHA-256 hashes for integrity verification
* - Download timestamp: ISO 8601 format
* - Schema version: From schema content
* - File size: Bytes
* - Validation status: Schema structure compliance
*
* Schema Validation Process:
* - Verifies JSON structure validity
* - Checks required fields: $schema, type, properties
* - Validates property definitions and types
* - Ensures schema references are resolvable
* - Reports validation errors with details
*
* Error Handling & Recovery:
* - Network errors: Retry with exponential backoff (max 3 attempts)
* - Malformed JSON: Skip schema with warning, continue others
* - Storage errors: Report and abort synchronization
* - Partial failures: Sync remaining schemas, report summary
*
* Integration Points:
* - Consumed by validate-against-cia-schemas.js (data validation)
* - Consumed by generate-types-from-cia-schemas.js (type generation)
* - Triggered by check-cia-schema-updates.js (change detection)
* - Referenced by CI/CD pipeline (schema compatibility gates)
*
* Usage Scenarios:
* 1. Initial setup: node scripts/sync-cia-schemas.js
* 2. Scheduled sync: Run hourly via CI/CD cron job
* 3. Manual sync: Run when new CIA data products available
* 4. Offline mode: Use locally cached schemas if remote unavailable
*
* Network Performance:
* - ~19 schemas × 3-5 KB average = 60-95 KB total
* - Parallel downloads: ~1-2 seconds typical
* - Checksum computation: < 100ms
* - Total execution: 2-3 seconds with network latency
* - Rate limiting: GitHub allows 60 API requests/hour unauthenticated
*
* Data Integrity:
* - SHA-256 checksums detect file corruption
* - Metadata timestamps track synchronization history
* - Version control integration tracks schema changes
* - Audit trail for compliance and incident investigation
*
* Compatibility Management:
* Supports backward compatibility with older schema versions:
* - Maintains schema version in metadata
* - Enables migration tracking of data product evolution
* - Supports version-specific validation rules
* - Handles schema deprecation gracefully
*
* ISMS Compliance:
* - ISO 27001:2022 A.8.1 - Asset management (schema inventory)
* - ISO 27001:2022 A.12.6.1 - Change management (version control)
* - ISO 27001:2022 A.14.2.1 - Supply chain security (CIA dependency management)
* - NIST CSF 2.0 RC.IM-2 - Incident management and improvements
* - CIS Control 3.3 - Data governance and management
*
* Security Considerations:
* - HTTPS-only communication with GitHub CDN
* - No credential storage (public repository)
* - File permissions: Read-only for schema files
* - Metadata directory: Write permission for update tracking
* - No secrets or sensitive data in schemas
*
* Output/Reporting:
* - Execution log: Schema fetch attempts and outcomes
* - Summary report: Total schemas, success count, failures
* - Updated metadata: ./schemas/metadata/cia-schemas-metadata.json
* - Exit code: 0 for success, 1 for failures
*
* Usage:
* node scripts/sync-cia-schemas.js
* # Fetches all 19 schemas from CIA repository
* # Validates and caches locally
* # Updates metadata with checksums and timestamps
*
* Environmental Factors:
* - Network connectivity required
* - Disk space: ~100 KB for all schemas
* - File system write permissions in ./schemas/
* - No external dependencies beyond Node.js
*
* @intelligence Essential infrastructure for data product compatibility
* @osint External dependency: CIA open-source intelligence schemas
* @risk Synchronization failure leaves system with stale schema definitions
* @gdpr No personal data processed (schema definitions only)
* @security HTTPS verification of remote source; no authentication secrets stored
