Key Features

per-item unique IDs - Uses a hybrid system of per-item unique IDs and per-item unique IDs to safely detect duplicated items without false positives.

Lineage-Aware Serialization (For stackable items) - Players can now combine similar stackable items even when items carry different lineage / NBT data. - Lineage serial ranges are merged correctly - No data is lost - Inventory consolidation behaves like vanilla Minecraft

Inventory & Cross-Inventory Scanning - Detects duplicate items within a player’s inventory and across all online players. Keeps legitimate copies and removes only excess items.

display name - Track custom items by display name, not NBT or material, preventing renamed items from bypassing detection.

Per-Item Hash Modes - `NAME` – stackable items share a deterministic hash (ideal for currencies like Money Sachets) - `UNIQUE` – non-stackable or special items get a unique ID per item

Custom Stack Sizes (Per Item) - Define allowed stack sizes for both vanilla and custom items via commands or config.

Always-Scanned Custom Items - Custom items are always checked, even when `onlyscan` mode or material exclusions are enabled.

Multi-Language Support - Added in game language support for the following. ``` de_DE en_US es_ES fr_CA fr_FR it_IT ja_JP pl_PL pt_BR ru_RU tr_TR uk_UA zh_CN ```

Safe Removal & Recovery System - Excess duplicate items are backed up to `recovery.yml` instead of being deleted.

Multi-Language Discord Webhook Alerts (Embed Messages) - Sends rich embed notifications in multiple languages to a Discord channel when a duplication is detected. Multi-Language Discord Webhook Alerts (Embed Messages))

Admin Whitelist - Exempt trusted players from all anti-dupe checks.

OnlyScan Mode - Scan only high-value items for performance, while still protecting all custom items.

Automatic Ban Option - Optionally bans players caught duplicating, with full logging.

Hot Reload Support - Reload custom item rules, stack sizes, hash modes, language files, and Discord config without restarting the server.

Detailed Logging - Duplication attempts logged in `dupe_log.yml`, bans recorded in `bans.yml`.
