Requirements Roadmap Matrix

Last Updated: 2025-12-23  
Version: 3.0  
Status: Authoritative Source  

Phase Definitions

Phase Philosophy: Each phase builds on proven capabilities from previous phases. We validate AI quality before adding production features.

Requirement Categories

This matrix covers two types of requirements:

• • 1. Formal System Requirements (16 requirements: FR4, FR7, FR44-FR54, NFR11-NFR13)

These are the primary requirements with full specifications in the Requirements page.

2. POC-Specific Requirements (FR1-FR2, FR5-FR6, FR11, FR13, NFR1-NFR3)

These are detailed in POC Requirements for POC1 implementation but do not have separate formal specification sections.

Mapping: POC-specific requirements are implementation-level details of formal requirements. For example:

• FR1 (Claim Extraction), FR2 (Context), FR3 (Scenarios), FR5 (Evidence Collection), FR6 (Source Quality) → All part of FR7 (Automated Verdicts)
• FR11 (Audit Trail) → Part of NFR11 (Quality Assurance)
• NFR1-NFR3 (Explainability, Performance, Transparency) → Addressed in NFR11 and NFR13

Requirements by Phase

Note: Requirements are organized by release and sorted by Urgency (HIGH → MEDIUM → LOW), then Importance (CRITICAL → HIGH → MEDIUM → LOW).

POC1

Goal: Prove that AI can extract claims and determine verdicts automatically

Experimental Feature: Context-aware analysis (tests if article credibility differs from claim average)

Requirements: 2 formal + 7 POC-specific

Context-Aware Analysis Details:

• Approach: Single-Pass Holistic Analysis (Approach 1)
• Implementation: Enhanced AI prompt to evaluate logical structure
• Testing: 30-article test set (10 straightforward, 10 misleading, 10 complex)
• Success Criteria: ≥70% accuracy detecting misleading articles
• Decision Path: If ≥70% → ship in POC2; if 50-70% → try weighted aggregation; if <50% → defer
• Cost: Zero increase (no additional API calls, no architecture changes)
• Documentation: Article Verdict Problem

POC2

Goal: Improve system reliability and add essential quality features

Requirements: 3 formal

Beta 0

Goal: Prepare for public launch with essential user-facing features and security

Requirements: 2 formal + 2 POC-specific

V1.0

Goal: Full production launch with IFCN compliance and search engine visibility

Requirements: 4 formal

V1.1

Goal: Add advanced capabilities

Requirements: 2 formal

V1.5

Goal: Media verification expansion (image, video, audio)

Requirements: 4 formal

Requirements Summary by Phase

Total Unique Requirements: 17 formal + 9 POC-specific = 26 total

User Needs by Phase

Summary of when each User Need is fulfilled:

Total User Needs: 20 (UN-1 to UN-28, with gaps)

Note: UN-29 to UN-36 reserved for future user needs from Gap Analysis

Key Changes in V3.0

This version includes important updates:

1. Context-Aware Analysis Added to POC1
      - FR4 enhanced to test context-aware analysis (experimental)
      - Tests if article credibility differs from simple claim average
      - Approach 1: Single-Pass Holistic Analysis
      - Success: ≥70% accuracy → ships in POC2
      - See Article Verdict Problem

2. Media Verification Moved to V1.5
   - FR46 (Image Verification): V1.0 → V1.5
   - FR51 (Video Verification): V1.1 → V1.5
   - FR47 (Archive.org Integration): Beta 0 → V1.5
   - Rationale: Focus V1.0 on core text-based fact-checking

3. Security Hardening Earlier
   - NFR12 (Security Controls): V1.0 → Beta 0
   - Ensures production security before public launch

4. Future Requirement Numbering Established
   - FR55-FR84 reserved for future functional requirements
   - NFR14-NFR18 reserved for future non-functional requirements
   - UN-29 to UN-36 reserved for future user needs
   - Prevents conflicts with existing baseline (FR1-FR54, NFR1-NFR13, UN-1 to UN-28)

Requirements Without Phase Assignments

Current Status: All 17 formal requirements have phase assignments ✅

Gap Analysis Features (Not Yet Formal Requirements):

The following features from Gap Analysis are not yet assigned formal requirement numbers but would use FR55+, NFR14+, UN-29+ when formalized:

Category 1: Accessibility (2 gaps)

• WCAG 2.1 Compliance
• Multilingual Support

Category 2: Platform Integration (2 gaps)

• Browser Extensions
• Embeddable Widgets

Category 3: Media Verification (3 gaps)

• Image Verification (informal → FR46 in V1.5)
• Video Verification (informal → FR51 in V1.5)
• Audio Verification (not yet formalized)

Category 4: Mobile & Offline (2 gaps)

• Mobile Apps / PWA
• Offline Access

Category 5: Education (2 gaps)

• Educational Resources
• Media Literacy Integration

Category 6: Collaboration (2 gaps)

• Professional Collaboration Tools
• Community Discussion

Category 7: Advanced Features (2 gaps)

• User Analytics
• Personalization

Total: 15 gap features not yet formalized as requirements
