CogTrade v1.1.0 Release Notes

---

🔄 NEW: Direct Player-to-Player Live Trading System

Players can now securely trade items and coins with each other in real time. All transactions are fully server-side synchronized — no item or coin loss is possible.

Commands

Command	Description
/trade offer <player>	Send a trade request (TAB completion supported)
/trade accept	Accept an incoming trade request
/trade reject	Reject an incoming trade request
/trade cancel	Cancel your active trade session

Features

• 30-second request timeout — unanswered requests expire automatically
• Each player can offer up to 9 item slots and a coin amount
• Coin offer field updates in real time as you type
• Dual-confirmation system — trade only completes when both players press READY
• Changing any offer automatically resets ready states (prevents last-second swaps)
• Trade completion plays a notification sound and shows a summary message

Security & Anti-Exploit

• Double-finalization lock — session.deactivate() prevents any race condition where the trade could complete twice
• Trade is blocked if either player's inventory is full (stack-merging is accurately simulated before committing)
• Insufficient coin balance causes the trade to abort and all items to be returned safely
• Items belonging to offline players are queued in PendingItemReturn and delivered on next login — zero item loss guaranteed
• Active sessions are safely aborted on disconnect or death

Audit Logging

• All completed trades are written to the direct_trades database table for server-side history

🖥️ IMPROVED: Trade GUI

• Left panel (your offer) — green-tinted background
• Right panel (partner's offer) — yellow-tinted, read-only with lock indicator
• Left click → move entire stack to offer slot
• Right click → move a single item
• Middle click → opens a floating quantity editor (type exact amount, press Enter to apply)
• Live status bar shows current state: "Partner is ready — confirm your side!", "Both players ready!", etc.
• Closing the screen automatically sends a cancel packet to safely end the session

• Removed beam/tracer visual effects from MarketLocateRenderer (performance improvement)
• Fixed search box overflow in MarketScreen
• Fixed active listing overlap in TradePostScreen
• Fixed price/stock layout overlap in the player market detail panel
