Key Implementation Notes

7-Point Verdict Scale:

• TRUE (86-100%) / MOSTLY-TRUE (72-85%) / LEANING-TRUE (58-71%)
• MIXED (43-57%, high confidence) / UNVERIFIED (43-57%, low confidence)
• LEANING-FALSE (29-42%) / MOSTLY-FALSE (15-28%) / FALSE (0-14%)

KeyFactors: Optional decomposition questions discovered during analysis - not stored as separate entities.

Storage: All data stored as JSON blob in SQLite ResultJson field.
