- Filters dangerous NBT, item-stack, entity-metadata, block-entity, bundle, and chunk packets.
- Can quarantine bad chunks and bad entities so follow-up packets keep getting blocked instead of re-triggering the same trap.
- Raw packet decode protection drops oversized/dangerous clientbound packets earlier in the network path via
PacketDecoderMixin. - Escape Mode and hard quarantine controls for severe chunkban situations.
- Can sanitize embedded chunk block-entity records, strip dangerous records while preserving terrain, and optionally allow safe terrain/light/block updates for bad chunks.
- Configurable limits for chunk size, block entity NBT, item stack NBT/components, suspicious packet size, bundle inspection, item-stack carrier packets, entity metadata, and fail-closed exception handling.
- Session summaries include blocked chunks, block entities, entity metadata packets, item stack carrier packets, bundle scans, and quarantine counts.
