Quality Gates (Implemented)

Gates 2 (Contradiction Search) and 3 (Uncertainty Quantification) are not yet implemented.

KeyFactors (Replaces Scenarios)

KeyFactors are optional decomposition questions discovered during the understanding phase:

• Not stored as separate entities
• Help break down complex claims into checkable sub-questions
• See Docs/ARCHITECTURE/KeyFactors_Design.md for design rationale

7-Point Verdict Scale

• TRUE (86-100%) - Claim is well-supported by evidence
• MOSTLY-TRUE (72-85%) - Largely accurate with minor caveats
• LEANING-TRUE (58-71%) - More evidence supports than contradicts
• MIXED (43-57%, high confidence) - Roughly equal evidence both ways
• UNVERIFIED (43-57%, low confidence) - Insufficient evidence to determine
• LEANING-FALSE (29-42%) - More evidence contradicts than supports
• MOSTLY-FALSE (15-28%) - Largely inaccurate
• FALSE (0-14%) - Claim is refuted by evidence
