BeaconAudit

BeaconAudit checks why a vanilla Minecraft Java Edition beacon structure cannot activate.

Hold paper, sneak, and use it on a beacon. Private system messages report:

• The number of complete pyramid layers
• The first invalid base-block coordinate, layer, and block name
• The first light-blocking block above the beam
• Whether the next manual check is payment and effect selection

BeaconAudit is read-only. It never builds, repairs, activates, pays, configures, or chunk-loads a beacon. It validates vanilla beacon-base tags and vanilla beam-blocking light behavior. It does not claim compatibility with mods that replace those rules.

Use requires paper plus sneak-use on a beacon block. Paper is not consumed.

Requirements:

• Minecraft Java Edition 1.21.11
• Fabric Loader 0.19.3 or newer
• Fabric API 0.141.6+1.21.11 or newer for Minecraft 1.21.11
• Java 21

Install BeaconAudit and Fabric API on the dedicated server. Connecting players do not need the mod. Install both locally for singleplayer.
