Fix IpRiskResponse decoding when ip_risk field is missing#645
Merged
Conversation
The ipRisk field now uses useDefault=true, so it defaults to 0.0 when not present in the database record. A value of 0.0 indicates the risk score was not set. Added tests for IP Risk database reading. Also updates maxmind-db submodule to include test data for records without ip_risk field. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
