🧠 Economic Intelligence — Now Real

The Economic Intelligence Engine has been completely rewritten. All calculations now use real server data instead of placeholder values.

What Changed

• Liquidity injection now calculates the optimal amount based on your server's actual money supply, health deficit, velocity gap, and active player count. Previously it injected a flat $10,000 regardless of conditions.
• Player stimulus distribution is now weighted by each player's economic activity and personality. Active traders and investors receive proportionally more; hoarders and exploiters receive less.
• Velocity of money is now tracked in real-time from actual transaction volume vs total money supply. This metric was previously never updated.
• Economic health is now a composite of 5 real indicators: wealth distribution (Gini), transaction flow, market activity, inflation rate, and player participation.
• All economic metrics (total money supply, average balance, transaction volume, market activity) now query the database directly instead of returning hardcoded estimates.

Persistence Across Restarts

The intelligence engine no longer loses its memory when the server restarts:

• Economic snapshots are saved to the database every 5 minutes and restored on startup (last 24 hours).
• Player economic profiles (personality, credit score, risk/trust scores, transaction history) are now persisted and survive restarts.
• Old snapshot data is automatically cleaned up after 7 days.

Pattern Recognition

The system now identifies real patterns:

• Daily activity cycles — detects peak and trough hours on your server.
• Volatility periods — flags when the economy is unstable (>10% health swings in 30-minute windows).
• Cycle rhythm — tracks average cycle duration and most common transitions to improve predictions.

Dynamic Interest Rates

Bank interest rates now respond to economic conditions automatically:

• During downturns: rates increase to reward saving.
• During booms: rates decrease to encourage spending.
• High inflation: rates increase to discourage borrowing.
• The adjustment is applied proportionally to all bank tiers.

🗄️ New Database Tables

Two new tables are created automatically on first startup:

Table	Purpose
ecoxpert_economic_snapshots	Stores economic state every 5 minutes for learning
ecoxpert_player_profiles	Persists player behavior analysis across restarts

No manual migration required — tables are created automatically.

🐛 Bugs Fixed

• Fixed: Player economic profiles were never saved to database (lost on restart).
• Fixed: Velocity of money placeholder always returned 1.0 regardless of actual activity.
• Fixed: Economic health calculation used hardcoded values instead of real wealth distribution.
• Fixed: Interest rate adjustments were only logged, never applied to the banking system.
• Fixed: Liquidity injection always distributed $100 per player regardless of economic conditions.

📦 Update Instructions

1. Stop server
2. Replace EcoXpert-1.3.1.jar with EcoXpert-1.4.0.jar
3. Start server
4. No configuration changes required — new tables are created automatically

Notes

• The intelligence engine will start with a fresh learning state on first boot (no historical snapshots from pre-1.4). After ~1 hour of operation it will have enough data for trend analysis; after ~4 hours for forecasting.
• Existing modules/inflation.yml policy parameters are fully compatible. No changes needed.
• If you use MySQL, the new tables use the same charset/engine as existing tables.
