EventTrace 1.0.0 - Minecraft 1.21.11 - Fabric

Release build for Minecraft 1.21.11 / Fabric. Tested loader: 0.19.5. Java 21. Optional on client and dedicated server; each side traces independently.

Installation

Install only eventtrace-1.0.0+mc1.21.11-fabric.jar in the matching instance's mods folder. Requires Fabric API 0.141.6+1.21.11, matching this Minecraft version.

Also add this startup JVM argument (not a chat command), pointing to the same JAR:

-javaagent:mods/eventtrace-1.0.0+mc1.21.11-fabric.jar

Use an absolute path if the launcher starts outside the game directory. Without the startup agent, tracing is disabled.

Changes and verification

• Added this exact version/loader port with the shared tracing core and native GUI.
• Packaged client and dedicated-server tracing checks passed.
• Tracing is off by default; no telemetry or automatic uploads.

Coverage and limitations

Dispatcher coverage: PARTIAL. This is not tracing of arbitrary mod behavior. Only recognized callback dispatch loops are traced. Arbitrary Mixins, custom callback factories and direct single-listener paths are outside coverage. This unchanged Fabric JAR was also tested on Quilt 0.31.0-beta.4 with the listed Fabric API; no stable-Quilt or QFAPI compatibility claim. The GUI browses local-client traces. Remote server trace GUI and optional script-line integrations are not implemented. Capture is bounded and Unknown ownership is intentional when evidence is insufficient. Disabled capture is not allocation-free. Game validation ran on macOS; no native Windows/Linux or exhaustive modpack gameplay test is claimed.
