## ✅ **Validation: Research Persona Storage**

**Status**: ✅ **Confirmed - Research persona is successfully stored in database**

**Validation Results**:
- PersonaData record exists with ID: 1
- Research persona field is populated (not None)
- Generated at: 2025-12-31 11:47:49
- Contains all expected fields:
  - `default_industry`: "Content Marketing"
  - `default_target_audience`: (populated)
  - `research_angles`: Array of research angles
  - `recommended_presets`: Array of personalized presets
  - `suggested_keywords`: Array of suggested keywords

## 🎯 **Implementation: Personalized Placeholders**

### **What Was Changed:**

#### **1. Enhanced Placeholder Function** (`placeholders.ts`)

**Added**:
- ✅ `PersonaPlaceholderData` interface to type persona data
- ✅ Enhanced `getIndustryPlaceholders()` to accept optional persona data
- ✅ Logic to generate placeholders from:
  - **Research Angles**: First 3 angles formatted as research queries
  - **Recommended Presets**: First 2 presets with their keywords and descriptions
- ✅ Fallback to industry defaults if persona data is unavailable

**How It Works**:
```typescript
// If research persona exists:
1. Extract first 3 research_angles → Format as placeholders
2. Extract first 2 recommended_presets → Use keywords + descriptions
3. Combine with 2 industry defaults as backup
4. Return personalized placeholders array

// If no persona:
1. Fall back to industry-specific defaults
```

#### **2. Updated ResearchInput Component** (`ResearchInput.tsx`)

**Added**:
- ✅ `researchPersona` state to store persona data
- ✅ Logic to extract persona data from `config.research_persona`
- ✅ Pass persona data to `getIndustryPlaceholders()` function

**Flow**:
```
Component Mount
  ↓
Load Research Config
  ↓
Check if research_persona exists
  ↓
Extract research_angles and recommended_presets
  ↓
Store in researchPersona state
  ↓
Pass to getIndustryPlaceholders(industry, personaData)
  ↓
Display personalized placeholders
```

## 📊 **Placeholder Generation Logic**

### **Priority Order:**

1. **Research Angles** (if available)
   - Format: `"Research: {angle}"` or use angle as-is if it contains `{topic}` placeholder
   - Example: `"Research: Compare {topic} tools"` → `"Research: Compare Content Marketing tools"`
   - Adds helpful description: "This will help you: Discover relevant insights..."

2. **Recommended Presets** (if available)
   - Uses preset keywords directly
   - Includes preset description if available
   - Example: Uses actual preset keywords from persona

3. **Industry Defaults** (fallback)
   - Uses original industry-specific placeholders
   - Only used if no persona data or as backup

### **Example Output:**

**With Research Persona**:
```
Research: Compare Content Marketing tools

💡 This will help you:
• Discover relevant insights and data
• Find authoritative sources and experts
• Get comprehensive analysis tailored to your needs

---

Research latest content marketing automation platforms for B2B SaaS companies

💡 Analyze competitive landscape and identify top content marketing tools and strategies
```

**Without Research Persona** (fallback):
```
Research: Latest AI advancements in your industry

💡 What you'll get:
• Recent breakthroughs and innovations
• Key companies and technologies
• Expert insights and market trends
```
