Editorial method
Evidence over enthusiasm.
JDun Trades is designed to make changing rules legible without pretending that editorial data is permanent.
Primary-source first
Firm websites, help centers, terms, and checkout pages should anchor every researched record.
Conflicts stay visible
When official sources disagree, the product should show the disagreement instead of silently choosing.
No cached certainty
Pricing and promotions are verified at the source. Seed data never invents a current price.
Explainable matching
Recommendations come from deterministic preferences that a beginner can inspect and understand.
