AntiDupePro

[2.7.0] - 2026-05-30

Added

• Per-entity pickup history: every item-entity UUID is recorded the first time it's picked up. If the same UUID is ever picked up again — which only happens for chunk-load dupes, drop-pickup race dupes, and cross-server-race dupes — the second pickup is flagged as a CRITICAL dupe alert and is not credited to the player's ledger balance.
• Pickup history is persisted across server restarts and prunes automatically after 30 days. Implemented across all three storage backends (SQLite uses a new pickup_history table; Redis uses SET NX with a 30-day TTL; in-memory uses ConcurrentHashMap).
