The Silent Auction
The bids were secret. The pattern was not.
Your role
Evidence is a system. Read it like one.
Find the only pair whose bid behavior proves coordinated manipulation.
First-case tutorial
What you actually do
- Identify the formal proxy timing pattern.
- Apply it consistently across every lot or bidder.
- Select the only candidate that reaches or violates the stated threshold.
Formal rules
- Linked pattern requires the same verified IP zone.
- The pair must update within one second on at least three lots.
Cases in this family rotate through multiple reasoning archetypes, so higher difficulty changes the deduction structure rather than simply adding more rows.
