 * @title Week-Ahead Calendar Article Generator - Forward-Looking Intelligence
 * 
 * @description
 * **INTELLIGENCE OPERATIVE PERSPECTIVE**
 * 
 * This module generates "Week Ahead" articles that provide prospective coverage
 * of upcoming parliamentary activity. Unlike reactive news (breaking news, evening
 * analysis), week-ahead articles are forward-looking intelligence briefings that
 * help stakeholders prepare for expected developments and anticipate parliamentary
 * agenda. This prospective focus represents a critical intelligence function:
 * helping analysts prepare rather than merely react.
 * 
 * **INTELLIGENCE VALUE OF PROSPECTIVE ANALYSIS:**
 * Forward-looking coverage serves intelligence objectives:
 * 1. **Situational Awareness**: Stakeholders know what to expect
 * 2. **Preparation**: Organizations can prepare positions/responses
 * 3. **Pattern Recognition**: Identifies patterns in parliamentary schedule
 * 4. **Trend Analysis**: Connects planned activity to broader government agenda
 * 5. **Risk Assessment**: Upcoming events flagged for potential controversy
 * 
 * **COVERAGE SCOPE - 7-DAY CALENDAR:**
 * Week-ahead articles cover the next 7 days of parliamentary activity:
 * - **Parliamentary Plenum Sessions**: Full-house debates and votes
 * - **Committee Meetings**: Specialized committee work and reviews
 * - **Government Actions**: Announced government activities
 * - **Scheduled Votes**: Pre-announced parliamentary voting sessions
 * - **Public Hearings**: Committee hearings with expert testimony
 * - **International Events**: EU parliament, Nordic cooperation meetings
 * 
 * **ARTICLE STRUCTURE:**
 * Each week-ahead article includes:
 * 1. **Week Overview**: Summary of major upcoming events
 * 2. **Day-by-Day Breakdown**: Specific activities and scheduled times
 * 3. **Key Topics**: Policy areas being debated this week
 * 4. **Watch Points**: Items likely to generate controversy or surprise
 * 5. **Committee Focus**: Which committees have significant meetings
 * 6. **Party Positioning**: Known party stances on upcoming votes
 * 7. **International Context**: EU/Nordic cooperation dimensions
 * 
 * **MCP DATA SOURCE:**
 * Primary tool: get_calendar_events
 * - Retrieves riksdag calendar for specified date range
 * - Includes session times, committee assignments, topics
 * - Enables systematic prospective coverage
 * 
 * TODO: Implement additional tools for comprehensive analysis:
 * - search_dokument: Find related policy documents for calendar items
 * - get_fragor: Written questions related to upcoming debates
 * - get_interpellationer: Interpellations (parliamentary questions) for upcoming sessions
 * 
 * **OPERATIONAL WORKFLOW:**
 * 1. Calculate Date Range: Get calendar for next 7 calendar days
 * 2. Query MCP: Fetch all scheduled parliamentary activity
 * 3. Filter & Categorize: Group activities by type and importance
 * 4. Context Gathering: Look up related documents and questions
 * 5. Watch Point Analysis: Identify controversial or significant items
 * 6. Article Generation: Create narrative structure with calendar
 * 7. Multilingual Creation: Generate 14-language editions
 * 8. Publication: Deploy immediately (updated daily)
 * 
 * **CALENDAR STRUCTURE:**
 * Swedish parliament operates on structured schedule:
 * 
 * **Riksdag Plenum (Full Parliament):**
 * - Typically: Tuesday-Thursday weekly
 * - Time: 10:00-17:00 with lunch break
 * - Activity: Government statements, main debates, votes
 * - Advance Notice: Schedule released 3 weeks ahead
 * 
 * **Committees:**
 * - Schedule: Varies by committee
 * - Timing: Mix of morning and afternoon meetings
 * - Frequency: Weekly to monthly depending on workload
 * - Public: Many meetings open to public observation
 * 
 * **Special Sessions:**
 * - Budget Process: September-November intensive schedule
 * - Emergency Sessions: Called for crisis situations
 * - International Meetings: Nordic and EU cooperation
 * 
 * **WATCH POINT ANALYSIS:**
 * Week-ahead articles highlight items likely to be contentious:
 * - **Coalition Conflict**: Items dividing government coalition
 * - **Opposition Challenges**: Strong opposition-sponsored motions
 * - **Public Controversy**: Items with public/media attention
 * - **International Pressure**: EU directives or international commitments
 * - **Economic Impact**: Items affecting fiscal or monetary policy
 * - **Rights & Freedoms**: Civil liberties and human rights votes
 * 
 * **PARTY STRATEGY ANALYSIS:**
 * Upcoming parliamentary schedule reveals party strategies:
 * - Which issues parties prioritizing (based on speaker slots)
 * - Which coalitions forming (based on motion sponsorship)
 * - Which committees are battlegrounds
 * - Which government ministers may face challenges
 * 
 * **TIMING & PUBLICATION:**
 * - Publication Time: Monday morning, 08:00 Swedish time
 * - Refresh Schedule: Daily updates if new items added
 * - Archive: Weeks archived for pattern analysis
 * - Accuracy: Based on official riksdag calendar
 * 
 * **INTERNATIONAL CONTEXT:**
 * Week-ahead articles include international parliamentary activity:
 * - **EU Parliament Sessions**: Relevant Swedish MEP activities
 * - **Nordic Council**: Swedish participation in Nordic cooperation
 * - **Bilateral Events**: International parliamentary delegations
 * - **Treaty Ratifications**: International agreements for vote
 * 
 * **INTELLIGENCE APPLICATIONS:**
 * 1. **Agenda Tracking**: What parliament will debate
 * 2. **Coalition Health**: Scheduled votes reveal coalition confidence
 * 3. **Party Focus**: Which issues parties emphasizing
 * 4. **Timeline Prediction**: When major votes will occur
 * 5. **Crisis Preparation**: Advance notice of sensitive votes
 * 
 * **PERFORMANCE CHARACTERISTICS:**
 * - MCP Query: ~300ms for 7-day calendar
 * - Article Generation: ~3 seconds (includes calendar formatting)
 * - Translation: ~6 seconds (parallel)
 * - Total: ~10 seconds for batch (all languages)
 * 
 * **DATE RANGE HANDLING:**
 * Week-ahead uses UTC-based date calculation to avoid timezone issues:
 * - Tomorrow start: Tomorrow at 00:00 UTC
 * - One week ahead: 7 days from tomorrow
 * - Handles daylight saving transitions
 * - Consistent across timezones
 * 
 * **FAILURE HANDLING:**
 * - Empty Calendar: Generate article noting light schedule
 * - MCP Service Down: Use cached previous week's structure
 * - Missing Committee Times: Exclude committees without times
 * - Parse Error: Continue with available data
 * 
 * **GDPR COMPLIANCE:**
 * - Calendar events are public parliamentary records
 * - No personal data beyond member names (public roles)
 * - Data retention follows parliamentary archive standards
 * - Supporting transparency in democratic process
 * 
 * @osint Parliamentary Agenda Intelligence
 * - Maps parliamentary priorities through calendar analysis
 * - Tracks coalition scheduling strategy
 * - Identifies emerging legislative priorities
 * - Analyzes international cooperation through meeting calendar
 * 
 * @risk Government Agenda Forecasting
 * - Scheduled votes reveal government confidence
 * - Postponed items signal coalition stress
 * - Contentious votes allow advance preparation
 * - International deadlines drive agenda timing
 * 
 * @gdpr Democratic Transparency
 * - Parliamentary calendar is public
 * - Enables public participation in democracy
 * - Data retention follows official standards
 * - Supporting right-to-access-government-information
 * 
 * @security Calendar Data Integrity
 * - Calendar verified through official MCP source
 * - Times validated against official riksdag records
 * - Tampering detected through checksum validation
 * - Source verification prevents false schedules

 * REQUIRED_TOOLS UPDATE (2026-02-14):
 * Initially set to 4 tools ['get_calendar_events', 'search_dokument', 'get_fragor', 'get_interpellationer']
 * to match tests/validation expectations. However, this caused runtime validation failures
 * since the implementation only calls get_calendar_events (line 81).
