The .mmdb files and GeoIP2-Country-Test.json are MaxMind's published test data from github.com/maxmind/MaxMind-DB, dual licensed MIT or Apache-2.0 (LICENSE-MIT, LICENSE-APACHE beside this file). All were fetched at commit 276926d23b4109ca5452709bfb5931c338afb34c. They contain test records only, not real geolocation data. pathological-dag.mmdb is not MaxMind's: a 32-node IPv4 tree whose two children are both the next node (2^32 network paths), built for the geoip code review R8-1 regression. It must be refused by OpenMMDBVerified. pathological-empty-dag.mmdb is a 128-node IPv6 tree whose children share the next node and end in the empty sentinel: maxminddb's walk spends 2^128 steps inside one call. pathological-metadata.mmdb declares node_count 2^63, which overflows the library's own arithmetic and panics it. Both are for the geoip code review R9 regressions: only the console's verifier child may ever open them. pathological-bigmap.mmdb has one data record declaring a map of 16,843,036 entries: maxminddb allocates it before noticing the entries are missing. The verifier child's memory cap must contain it.
