}
```

**Location**: Lines 218-234

---

### Phase 3: Mapping Logic Implementation ✅

**Status**: Completed
**Duration**: ~20 minutes
**File Modified**: `/Users/a003/dev/miyabi-private/crates/miyabi-a2a/src/http/real_data.rs`

**Changes Made**: Implemented 5 helper functions (95 lines total)

#### 1. Priority Extraction Function

**Location**: Lines 688-697
**Purpose**: Extract priority from GitHub labels

```rust
fn extract_priority_from_labels(labels: &[String]) -> String {
    labels
        .iter()
        .find(|l| l.contains("priority:"))
        .and_then(|l| l.split(':').nth(1))
        .and_then(|p| p.split('-').next())
        .unwrap_or("P2") // Default to P2 (medium priority)
        .to_string()
}
```

**Example**:
- Input: `["🔥 priority:P0-Critical", "✨ type:feature"]`
- Output: `"P0"`

---

#### 2. Duration Estimation Function

**Location**: Lines 699-710
**Purpose**: Estimate task duration based on agent type

```rust
fn estimate_minutes_from_agent(agent_type: &str) -> u32 {
    match agent_type {
        "coordinator" => 60,   // 1 hour for coordination/planning
        "codegen" => 45,       // 45 min for code generation
        "review" => 30,        // 30 min for code review
        "deploy" | "deployment" => 40, // 40 min for deployment
        "pr" => 15,            // 15 min for PR creation
        "issue" => 20,         // 20 min for issue analysis
        _ => 30,               // Default: 30 min
    }
}
```

**Example**:
- Input: `"codegen"`
- Output: `45` (minutes)

---

#### 3. Description Extraction Function

**Location**: Lines 712-737
**Purpose**: Extract first paragraph from issue body, clean markdown

```rust
fn extract_description_from_body(body: &String) -> String {
    // Take first paragraph (up to first double newline)
    let first_para = body
        .split("\n\n")
        .next()
        .unwrap_or(body)
        .trim();

    // Remove markdown formatting
    let cleaned = first_para
        .replace("**", "")
        .replace("*", "")
        .replace("#", "")
        .trim()
        .to_string();

    // Return truncated string or default
    if cleaned.is_empty() {
        "No description available".to_string()
    } else if cleaned.len() > 200 {
        format!("{}...", &cleaned[..200])
    } else {
        cleaned
    }
}
```

**Example**:
- Input: `"## Overview\n\nImplement Docker tests\n\n## Details\n..."`
- Output: `"Overview Implement Docker tests"`

---

#### 4. Module Mapping Function

**Location**: Lines 739-754
**Purpose**: Map agent type to module name

```rust
fn map_agent_to_module(agent_name: &str, agent_type: &str) -> String {
    match agent_type {
        "coordinator" => "Miyabi Coordinator",
        "codegen" => "Miyabi CodeGen",
        "review" => "Miyabi Review",
        "deploy" | "deployment" => "Miyabi Deployment",
        "pr" => "Miyabi PR",
        "issue" => "Miyabi Issue",
        _ => agent_name, // Fallback to Japanese agent name
    }
    .to_string()
}
```

**Example**:
- Input: `"つくるん", "codegen"`
- Output: `"Miyabi CodeGen"`

---

#### 5. Layer Inference Function

**Location**: Lines 756-779
**Purpose**: Infer architectural layer from agent type and labels

```rust
fn infer_layer_from_agent(agent_type: &str, labels: &[String]) -> String {
    // Check type labels first
    for label in labels {
        if label.contains("type:") {
            if label.contains("ui") || label.contains("frontend") {
                return "ui".to_string();
            } else if label.contains("infra") || label.contains("deploy") {
                return "infra".to_string();
            } else if label.contains("data") || label.contains("database") {
                return "data".to_string();
            }
        }
    }

    // Infer from agent type
    match agent_type {
        "deploy" | "deployment" => "infra",
        "review" | "issue" => "logic",
        "codegen" | "coordinator" | "pr" => "logic",
        _ => "logic", // Default to logic layer
    }
    .to_string()
}
```

**Example**:
- Input: `"deploy", ["🚀 type:deployment"]`
- Output: `"infra"`

---

#### Node Creation with Full Mapping

**Location**: Lines 856-874
**Purpose**: Apply all 5 helper functions during DAG node creation

```rust
// 🧬 Apply full parameter mapping using helper functions
let priority = extract_priority_from_labels(&issue.labels);
let estimated_minutes = estimate_minutes_from_agent(&agent_key);
let description = extract_description_from_body(&issue.body);
let module = map_agent_to_module(&japanese_name, &agent_key);
let layer = infer_layer_from_agent(&agent_key, &issue.labels);

nodes.push(DagNode {
    id: format!("task-{}", issue.number),
    label: issue.title.clone(),
    status: status.to_string(),
    agent: japanese_name,
    agent_type: agent_name.to_lowercase(),
    priority,
    estimated_minutes,
    description,
    module,
    layer,
});
```

---

### Phase 4: Frontend Type Definition Updates ✅

**Status**: Completed
**Duration**: ~10 minutes
**File Modified**: `/Users/a003/dev/miyabi-private/crates/miyabi-a2a/dashboard/src/components/vector-space-universe.tsx`

**Changes Made**:

#### Updated TypeScript Interface

**Location**: Lines 1008-1021

```typescript
interface DagNodeAPI {
  id: string;
  label: string;
  status: string;
  agent: string;
  agentType: string;
  // 🧬 Extended fields (Phase 2-3: Full Parameter Mapping)
  priority: string;           // "P0" | "P1" | "P2" | "P3"
  estimatedMinutes: number;
  description: string;
  module: string;
  layer: string;             // "ui" | "logic" | "data" | "infra"
}
```

#### Simplified Conversion Function

**Location**: Lines 1053-1074

```typescript
// 🧬 Use values directly from API (already processed by Rust backend)
return {
  id: node.id,
  title: node.label,
  status: statusMap[node.status] || "pending",
  priority: node.priority as Task["priority"],       // From API
  estimatedMinutes: node.estimatedMinutes,           // From API
  description: node.description,                     // From API
  module: node.module,                               // From API
  layer: node.layer as Task["layer"],                // From API
  dependencies,
};
```

**Benefit**: Removed duplicate calculation logic on frontend - all processing now happens in Rust backend

## 🐛 Issues Resolved

### Issue 1: Type Mismatch in extract_description_from_body()

**Error**:
```
error[E0308]: mismatched types
expected reference `&std::option::Option<std::string::String>`
found reference `&std::string::String`
```

**Root Cause**: Function signature expected `&Option<String>` but GitHub API returned `&String`

**Fix**: Changed function signature from:
```rust
fn extract_description_from_body(body: &Option<String>) -> String
```
to:
```rust
fn extract_description_from_body(body: &String) -> String
```

**Status**: ✅ Resolved
