* @module Intelligence/ContentQuality
* @category Intelligence Operations / Supporting Infrastructure
* @name Article Quality Enhancer - Economist-Style Content Validation Framework
*
* @description
* Comprehensive content quality assurance system implementing The Economist-style editorial standards
* for political journalism. This utility validates article structure, analytical depth, source attribution,
* and perspective diversity to ensure intelligence reporting meets rigorous transparency requirements.
*
* Core Functionality:
* - Validates analytical depth scoring (min 0.6 threshold) assessing complexity of political analysis
* - Enforces source quality standards requiring minimum 3 cross-referenced government documents/debates
* - Counts unique party perspectives (min 4 parties) ensuring balanced coverage across Swedish coalition
* - Detects "Why This Matters" contextual sections explaining political significance for readers
* - Validates historical context references connecting current events to parliamentary timeline
* - Calculates composite quality score (0.0-1.0 scale, min 0.75 threshold) for publication readiness
*
* Intelligence Operations Integration:
* - Supports ongoing parliamentary monitoring by maintaining content quality standards
* - Enables identification of systematic bias in coverage across party spectrum
* - Tracks journalistic methodology compliance with editorial guidelines
* - Documents source diversity for audit trails and GDPR data provenance
*
* Content Quality Standards:
* - Minimum analytical depth: 0.6 (evaluates substantive policy discussion)
* - Minimum cross-references: 3 (government documents, committee reports, voting records)
* - Minimum party perspectives: 4 (ensures broad political spectrum coverage)
* - Requires "Why This Matters" section for context and reader understanding
* - Recommends historical context linking current developments to past decisions
* - Minimum publication quality score: 0.75 (composite metric of all dimensions)
*
* Integration Points:
* - Consumed by news generation pipeline for automated quality gates
* - Referenced in editorial workflows for manual content enhancement
* - Used by CI/CD validation scripts (validate-news-translations.js, validate-articles-playwright.js)
* - Feeds metrics into intelligence dashboard for quality trending
*
* Data Handling:
* - Processes publicly available parliamentary records and published journalism
* - No processing of personal data (operates on aggregated article metrics)
* - Complies with ISO 27001:2022 A.14.2.1 (supply chain controls on content quality)
* - Supports GDPR Article 5 (transparency: all quality metrics documented)
*
* Usage:
* import { enhanceArticleQuality } from './article-quality-enhancer.js';
* const result = await enhanceArticleQuality(articlePath, options);
* // Returns: { qualityScore, analyticalDepth, partyCount, hasWhyThis, issues }
*
* @intelligence Core utility for content validation in political journalism platform
* @osint Validates open-source political documentation (government records, voting history)
* @risk Content quality failure may result in publication of unsubstantiated claims
* @gdpr No personal data processing; operates on published content only
* @security HTML/JavaScript injection prevented through article parsing
