// Chat History Management Enhancement
// ================================

// Summary of Changes Made:
// 1. Increased streaming processor history limit from 10 to 100 messages
// 2. Increased duplicate checking range from 10 to 50 messages
// 3. Added performance monitoring for large chat histories
// 4. Database schema already supports unlimited String[] messages

// Current Configuration:
const HISTORY_LIMITS = {
    // Messages kept in AI context for conversation continuity
    AI_CONTEXT_MESSAGES: 100, // Was: 10 (50 user + 50 AI pairs)

    // Messages checked for duplicates when saving new messages
    DUPLICATE_CHECK_MESSAGES: 50, // Was: 10

    // UI performance warning threshold
    UI_PERFORMANCE_WARNING: 200, // New: Shows console warning for very large histories

    // Database storage: UNLIMITED (PostgreSQL String[] array)
};

// Benefits of Increased Limits:
// ✅ Better conversation context for AI responses
// ✅ More comprehensive workout history access
// ✅ Improved duplicate detection accuracy
// ✅ Better long-term conversation memory
// ✅ Enhanced user experience for power users

// Performance Considerations:
// - Chat history loading: O(n) but cached in memory
// - Duplicate checking: O(n) with Set for optimization
// - UI rendering: React handles list virtualization well
// - Database: PostgreSQL arrays are efficient for this use case

console.log("- Duplicate Check Range: 10 → 50 (5x increase)");
console.log("- Database Storage: Unlimited");
