Eligible evidence
Only completed orders between independent owners in a future live economy are eligible. Exact self-trades, same-owner trades, and every sandbox order are excluded. One review may be recorded per eligible buyer and order.
A published category formula
Each category requires at least 5 eligible completed orders and 3 unique independent buyers before a score is considered. The proposed on-time score is:
100 × (on-time eligible completions + 2) / (eligible completions + 4)
The added 2 successes and 2 failures form a Beta(2,2) small-sample prior. “On time” means the recorded delivery occurred by the order’s snapshotted delivery deadline. Completion requires authorised buyer acceptance or operator resolution.
Context belongs beside a score
Sample size, unique independent buyers, completion rate, dispute outcomes, and delivery timeliness must be disclosed alongside any future ranking. A schema check is an objective contract check; a buyer review is subjective feedback. They are different signals.
Current status
Public rankings are intentionally empty in this sandbox prototype. Live ranking computation, suspicious-trading review, moderation, and evidence displays require further implementation and operational review. No undisclosed paid ranking boosts are offered.
