/**
* @module DataPipeline/CIADataLoader
* @category Intelligence Platform - Data Acquisition & Pipeline Management
*
* @description
* **CIA Intelligence Data Loader & Pipeline Orchestrator**
*
* Core data acquisition module implementing multi-source intelligence data loading
* from the Citizen Intelligence Agency (CIA) Platform. Manages CSV export ingestion
* for 19+ intelligence product categories and JSON fallback for model-generated
* electoral forecasts. Provides resilient data pipeline with local-first strategy
* and remote fallback capabilities.
*
* ## Data Pipeline Architecture
*
* **Multi-Tier Source Strategy**:
* ```
* Tier 1 (Local): ../cia-data/{category}/*.csv (deployed assets)
* Tier 2 (JSON): ../data/cia-exports/current/*.json (model outputs)
* Tier 3 (Fallback): GitHub Raw API (authoritative source)
* ```
*
* **Benefits**:
* - **Performance**: Local CSV loads ~10x faster than GitHub API
* - **Resilience**: Degradation from local → JSON → remote
* - **Offline**: Works with locally deployed data packages
* - **Freshness**: GitHub fallback ensures latest data availability
*
* ## Intelligence Product Categories
*
* **19 CIA Platform Export Types**:
*
* ### Structural Intelligence
* 1. **personStatus** - Active MP counts by status
* 2. **riskByParty** - Party-level risk aggregation
* 3. **riskLevels** - Aggregate risk distribution
* 4. **annualBallots** - Yearly voting activity
*
* ### Performance Metrics
* 5. **documents** - Document production statistics
* 6. **attendance** - Chamber/committee participation
* 7. **productivity** - Legislative output metrics
* 8. **effectiveness** - Bill passage rates
*
* ### Risk Assessment
* 9. **riskScores** - Quantitative risk scores (0-10 scale)
* 10. **ethicsConcerns** - Top 10 ethics cases
* 11. **electoralRisk** - Constituency vulnerability
* 12. **crisisResilience** - Crisis response effectiveness
*
* ### Behavioral Analysis
* 13. **votingAnomalies** - Anomaly detection classification
* 14. **partyDiscipline** - Voting cohesion metrics
* 15. **coalitionStability** - Coalition behavior patterns
*
* ### Temporal Intelligence
* 16. **seasonalPatterns** - Quarterly activity trends
* 17. **electionCycles** - Election period comparisons
* 18. **historicalTrends** - Multi-year pattern analysis
*
* ### Predictive Models
* 19. **electionForecasts** - 2026 election predictions (JSON)
*
* ## Data Source Mapping
*
* **CSV Sources** (Real PostgreSQL Views):
* - Local: `../cia-data/{category}/{view_name}.csv`
* - Remote: `https://raw.githubusercontent.com/Hack23/cia/master/service.data.impl/sample-data/{view_name}.csv`
*
* **JSON Sources** (Model-Generated):
* - Local: `../data/cia-exports/current/{product_name}.json`
* - Schema: CIA Platform JSON export format v2.0
*
* ## Intelligent Loading Strategy
*
* **Load Priority Algorithm**:
* ```javascript
* async loadData(category) {
* try {
* return await this.loadLocal(category); // Tier 1: Local CSV
* } catch (err) {
* try {
* return await this.loadJSON(category); // Tier 2: Local JSON
* } catch (err) {
* return await this.loadRemote(category); // Tier 3: GitHub
* }
* }
* }
* ```
*
* **Error Handling**:
* - Network failures: Retry with exponential backoff (3 attempts)
* - Parse errors: Fallback to next tier
* - Missing data: Return empty dataset with warning
* - CORS errors: Proxy through service worker (if available)
*
* ## Data Validation Pipeline
*
* **Quality Assurance Steps**:
* 1. **Format Validation**: CSV structure, delimiter, encoding (UTF-8)
* 2. **Schema Validation**: Required columns, data types
* 3. **Range Validation**: Numeric bounds, date ranges
* 4. **Completeness**: Missing value checks, null handling
* 5. **Freshness**: Timestamp validation (< 24 hours for real-time data)
*
* **Validation Rules**:
* - Risk scores: 0.0 ≤ score ≤ 10.0
* - Years: 2002 ≤ year ≤ 2025
* - Quarters: 1 ≤ quarter ≤ 4
* - Party codes: Must match official Riksdag codes (S, M, SD, etc.)
*
* ## Performance Characteristics
*
* **Load Times** (typical):
* - Local CSV: ~50ms for 1000 rows
* - Local JSON: ~30ms (pre-parsed)
* - GitHub API: ~500ms + network latency
*
* **Memory Usage**:
* - Per dataset: ~1-5MB raw data
* - Total cache: ~50MB for all 19 products
* - Browser limit: 10MB localStorage quota per origin
*
* ## Caching Strategy
*
* **Not Implemented in This Module**:
* Caching is responsibility of consumer modules (party-dashboard.js,
* risk-dashboard.js, etc.) using localStorage with appropriate TTLs.
* This module provides pure data loading without side effects.
*
* ## GDPR Compliance
*
* @gdpr All data sourced from public parliamentary records (Article 9(2)(e))
* No personal data processing beyond official public roles and voting records.
* All CIA Platform exports comply with Swedish Public Access to Information Act.
*
* ## Security Considerations
*
* @security Medium risk - External data sources, client-side processing
* @risk GitHub repository compromise could inject malicious data
*
* **Mitigation Strategies**:
* - Strict CSV parsing (no eval, no innerHTML)
* - Content Security Policy (CSP) enforcement
* - Subresource Integrity (SRI) for GitHub resources
* - Input sanitization before DOM insertion
*
* ## Integration Patterns
*
* **Usage Example**:
* ```javascript
* const loader = new CIADataLoader();
* const riskData = await loader.loadCSV('riskByParty');
* const forecast = await loader.loadJSON('electionForecast2026');
* ```
*
* **Consuming Modules**:
* - `cia-visualizations.js` - Dashboard renderer
* - `election-predictions.js` - Forecast visualizations
* - `dashboard-init.js` - Dashboard initialization
* - `risk-dashboard.js` - Risk assessment display
*
* @intelligence Multi-source data acquisition with intelligent fallback
* @osint CIA Platform exports, GitHub repository fallback, local-first strategy
* @risk External dependency on GitHub, data integrity validation required
