Your role
Evidence is a system. Read it like one.
Read tower coverage, outages and call records as a network, not a conversation.
First-case tutorial
What you actually do
- Build a cross-reference list before eliminating anyone.
- Find the broken relay bridge.
- Split the network into connected components.
- Find the completed call that crosses components.
Formal rules
- Blocked relays carry no traffic.
- No satellite or Wi-Fi calling was available.
Cases in this family rotate through multiple reasoning archetypes, so higher difficulty changes the deduction structure rather than simply adding more rows.
