Sign Leak Shield

Disclosure:

This mod was built with the help of AI.

This is a Fabric client mod for Minecraft 1.21.1 that defensively patches forced sign-editor translation and keybind leak probes.

Build and CI:

1. Install Java 21.
2. Build locally with ./gradlew build on Linux/macOS or gradlew.bat build on Windows.
3. The built jar will be placed in build/libs.
4. dev branch pushes and pull requests run the verification workflow in .gitea/workflows/dev-verify.yml.
5. main branch pushes and v* tags run the release workflow in .gitea/workflows/main-release.yml, which publishes a release and uploads the jar.

Notes:

• The project targets Fabric for Minecraft 1.21.1.
• The implementation is scoped to forced sign editor traffic and only rewrites matching outgoing sign update packets.
