LaunchGuard

LaunchGuard v0.3.0

Added:

• Optional startup preflight checks
• Saved plain text report files under plugins/LaunchGuard/reports/
• /launchguard history
• /launchguard history latest
• launchguard.history permission
• Report retention with settings.reportsToKeep

Startup Checks:

• LaunchGuard can run a preflight check automatically after server start
• Configurable with settings.runOnStartup and settings.startupDelayTicks
• Startup checks use the same configured checks as /launchguard run

Saved Reports:

• Reports can be saved as plain text files
• Manual reports and startup reports are supported
• Report files are stored under plugins/LaunchGuard/reports/
• Reports include timestamp, source, version, result, and pass/warn/fail counts

Report History:

• /launchguard history lists recent saved reports
• /launchguard history latest prints the latest saved report
• Large report output is truncated safely

Safety:

• LaunchGuard remains read-only
• LaunchGuard does not execute plugin commands
• LaunchGuard does not execute configured commands
• LaunchGuard does not install, download, enable, disable, or reload plugins
• LaunchGuard does not modify worlds, blocks, economy, permissions, whitelist, chunks, or players
• LaunchGuard does not send network requests
• Report retention deletes only .txt report files inside plugins/LaunchGuard/reports/

Compatibility:

• Tested on Paper 1.20.4
• Tested with Java 17
• Built with Java 17 target compatibility
• Use the Java version required by your Paper server version

Limitations:

• Startup checks use a configurable fixed delay
• Reports are plain text only
• Report history has no search or filter support
• Plugin inventory reports metadata, enabled state, and dependency visibility only
• LaunchGuard does not verify full plugin runtime behavior or plugin configuration correctness
