Purpur Sentinel

Passive, explainable movement-pattern observation for Purpur servers.

Sentinel gives permitted operators bounded evidence of repeated suspicious on-foot horizontal movement. It does not cancel movement, punish players, persist player evidence, or export telemetry.

Development

Requires Java 25 and Node.js 20.

./gradlew clean check jar

The output JAR is written to build/libs/. Production installation and deployment are separately gated operations.
