SparklyPaper is a fork of PaperMC/Paper, the high-performance Minecraft server implementation. It applies a curated set of custom performance and feature patches on top of upstream Paper, with a focus on server tick optimization and configuration via a sparklypaper.yml file. The build is Gradle-based and produces a patched server jar; CI workflows automatically track upstream Paper and build the project. The repository is structured as a standard Paper fork: a Gradle multi-project build with a sparklypaper-api module and a patched server module. The runtime entry point is the standard Paper patched Minecraft server main class; custom behavior is introduced through patches that modify world ticking, chunk loading, and player data handling. The sparklypaper.yml file controls per-world settings, with defaults and per-world overrides. External dependencies include upstream Paper, Minecraft server jars, Gradle, and GitHub Actions. The repository also contains design notes (PARALLEL_NOTES.md), performance results (RESULTS.md), and a curated list of known-broken patches from other forks (BORKED_PATCHES.md). It is not a library or service; it is a server distribution for running Minecraft servers. No test suite is visible; CI focuses on build and auto-update.
