Lineage-Aware Stack Consolidation

Players can now combine similar stackable items (e.g. 10 + 1 → 11) even when items carry different lineage / NBT data.

When stacks are merged:

• Lineage serial ranges are merged correctly
• No data is lost
• Inventory consolidation behaves like vanilla Minecraft

🔒 Dupe Detection Hardening (No Weakened Security)

• Cross-player and cross-inventory duplication still triggers hard removal
• Only same-player, same-inventory merge actions receive reconciliation
• Lineage overlap across players remains instantly detectable

⚙️ Thread Safety & Stability Improvements

• All inventory reads and mutations now run on the main server thread
• Eliminated async race conditions that caused:
• mid-merge scans
• phantom duplicates
• stack rollback behavior

📈 Result

• ✅ Vanilla-like inventory behavior restored
• ✅ No loss of anti-dupe integrity
• ✅ Stable stacking, splitting, and recombining
• ✅ No false positives during normal gameplay

If you do run into any problems please report them to me in our Discord chat.
