Chain of Custody
The evidence changed hands. Somewhere, it changed identity.
Your role
Evidence is a system. Read it like one.
Audit seals, weights, signatures and transfers to locate the compromised handoff.
First-case tutorial
What you actually do
- Match incoming and outgoing evidence tags for each row.
- Ignore handler names until the mismatch is found.
- Select the first changed identity.
Formal rules
- No authorized retagging occurred.
- A normal transfer preserves the evidence tag exactly.
Cases in this family rotate through multiple reasoning archetypes, so higher difficulty changes the deduction structure rather than simply adding more rows.
