Budget Refinement System

The budget system detects, infers, and adjusts budgets through multiple methods with transparent user communication.

Budget Detection Hierarchy

Budget Calculation Methods

1. Explicit Budget (Direct)

User: "Raamatuid kuni 25 euro"

Pattern Match: /kuni\s+(\d+)\s+euro/i → 25
Result: budget.max = 25

2. Range Budget

User: "Kingitus 15-35 euro vahemikus"

Pattern Match: /(\d+)\s*[-–]\s*(\d+)\s+euro/i → [15, 35]
Result: budget.min = 15, budget.max = 35

3. Implicit Budget (Cheaper Request)

Previous Products:
- Book A: €30
- Book B: €35
- Book C: €28

User: "odavamaid" (cheaper ones)

Calculation:
avgPrice = (30 + 35 + 28) / 3 = 31
implicitBudget = Math.floor(31 * 0.7) = 21

Result: budget.max = 21

Implementation:

if (giftContext.intent === 'cheaper_alternatives' && 
    !giftContext.budget?.max && 
    storedProducts.length > 0) {
  
  const prices = storedProducts
    .map(p => p.price)
    .filter((price): price is number => typeof price === 'number' && price > 0);
  
  if (prices.length > 0) {
    const avgPrice = prices.reduce((sum, p) => sum + p, 0) / prices.length;
    
    giftContext.budget = {
      max: Math.floor(avgPrice * 0.7),  // 30% reduction
      hint: 'odavam kui eelmised'
    };
    
    console.log(' IMPLICIT BUDGET CALCULATED:', {
      previousPrices: prices,
      avgPrice,
      implicitBudget: giftContext.budget.max
    });
  }
}

4. Occasion-Based Inference

User: "Isadepäeva kingitus"

Occasion Detection: "Isadepäev" (Father's Day)
Inferred Budget: { min: 20, max: 60 }

Estonian Occasion Budgets:

Occasion	Estonian	Budget (€)	Use Case
Father's Day	Isadepäev	20-60	Parent gift
Mother's Day	Emadepäev	20-60	Parent gift
Birthday	Sünnipäev	20-50	General
Christmas	Jõulud	25-80	Holiday gift
Midsummer	Jaanipäev	15-40	Casual gift

Budget Adjustment

Cheaper refinement:

// User requests cheaper alternatives
if (signals.cheaperRequested && giftContext.budget?.max) {
  const originalMax = giftContext.budget.max;
  giftContext.budget.max = Math.floor(giftContext.budget.max * 0.7);
  
  console.log(' BUDGET REDUCED:', {
    originalMax,
    newMax: giftContext.budget.max,
    reductionPercent: 30
  });
}

Example:

Turn 1: "Raamatuid kuni 50 euro"
        budget.max = 50

Turn 2: "Midagi odavamat" (something cheaper)
        budget.max = 50 * 0.7 = 35

Budget Chain Example

Turn 1: "Raamatuid sünnipäevaks"
Context: { productType: "Raamat", occasion: "sünnipäev" }
Inferred Budget: {min: 20, max: 50}
Response: [Book A (€45), Book B (€38), Book C (€42)]

Turn 2: "Kuni 30 euro"
Detected: budget.max = 30
Preserved: productType, occasion
Response: [Book D (€28), Book E (€25), Book F (€29)]

Turn 3: "Veelgi odavamaid"
Detected: cheaperRequested = true
Calculated: 30 * 0.7 = 21
Response: [Book G (€18), Book H (€15), Book I (€20)]

Turn 4: "Vahemikus 15-25 euro"
Detected: budget = {min: 15, max: 25}
Preserved: productType, occasion
Response: [Book H (€15), Book I (€20), Book J (€23)]
