## ✨ Core Features

### 1. Intelligent Memory Routing
Automatically selects the best retrieval method based on query type:

| Query Type | Method | Speed |
|------------|--------|-------|
| Recent context | HOT (SESSION-STATE) | <10ms |
| Facts & preferences | COLD (Vector search) | ~50ms |
| Causal relationships | WARM (Neural graph) | ~100ms |
| Long-term decisions | ARCHIVE (Git-Notes) | ~200ms |

### 2. Automatic Memory Lifecycle
```
Capture → Extract → Process → Store → Recall → Cleanup
   │          │         │        │       │        │
Input    Mem0/Auto   Importance  4-Layer  Smart   Periodic
Capture   Extraction   Scoring   Storage  Route   Hygiene
```

### 3. Neural Graph with Spreading Activation
- **Not keyword search** — Finds conceptually related memories through graph traversal
- **20 synapse types** — Temporal, causal, semantic, emotional connections
- **Hebbian learning** — Memories strengthen with use
- **Contradiction detection** — Auto-detects conflicting information

### 4. Experience Learning
```
Decision → Action → Outcome → Lesson
    │         │        │         │
   Store    Track    Record    Learn
```
- Tracks decisions and their outcomes
- Learns from errors
- Suggests based on past patterns

### 5. Smart Hygiene
- Auto-cleans junk memories
- Deduplicates similar entries
- Optimizes token usage
- Monthly maintenance mode

## 🚀 Quick Start

### Installation
```bash
clawhub install ichiro-mind
```

### Setup
```bash
# Initialize Ichiro-Mind
ichiro-mind init

# Configure MCP
ichiro-mind setup-mcp
```

### Basic Usage
```python
from ichiro_mind import IchiroMind

# Initialize
mind = IchiroMind()

# Store memory (auto-routes to appropriate layer)
mind.remember(
    content="User prefers dark mode",
    category="preference",
    importance=0.9
)

# Recall with smart routing
result = mind.recall("What mode does user prefer?")

# Learn from experience
mind.learn(
    decision="Used SQLite for dev",
    outcome="slow_with_big_data",
    lesson="Use PostgreSQL for datasets >1GB"
)
```

## 📝 Memory Layers in Detail

### HOT Layer — SESSION-STATE.md
Real-time working memory using Write-Ahead Log protocol.

```markdown
# SESSION-STATE.md — Ichiro-Mind HOT Layer

## Current Task
Building unified memory system

## Active Context
- User: 兵步一郎
- Project: Ichiro-Mind
- Stack: Python + LanceDB + Neural Graph

## Key Decisions
- [x] Use 4-layer architecture
- [ ] Implement MCP interface

## Pending Actions
- [ ] Write SKILL.md
- [ ] Create Python core
```

**WAL Protocol**: Write BEFORE responding, not after.

### WARM Layer — Neural Graph
Associative memory with spreading activation.

```python
# Store with relationships
mind.remember(
    content="Use PostgreSQL for production",
    type="decision",
    tags=["database", "infrastructure"],
    relations=[
        {"type": "CAUSED_BY", "target": "performance_issues"},
        {"type": "LEADS_TO", "target": "better_scalability"}
    ]
)

# Deep recall
memories = mind.recall_deep(
    query="database decisions",
    depth=2  # Follow causal chains
)
```

### COLD Layer — Vector Store
Semantic search with LanceDB.

```python
# Auto-captured from conversation
mind.auto_capture(text="User likes minimal UI")

# Semantic search
results = mind.search("user interface preferences")
```

### ARCHIVE Layer — Persistent Storage
Human-readable long-term memory.

```
workspace/
├── MEMORY.md              # Curated long-term
└── memory/
    ├── 2026-03-07.md      # Daily log
    ├── decisions/         # Structured decisions
    ├── entities/          # People, projects, concepts
    └── lessons/           # Learned experiences
```

## 🛠️ Advanced Features

### Memory Hygiene
```bash
# Audit memory
ichiro-mind audit

# Clean junk
ichiro-mind cleanup --dry-run
ichiro-mind cleanup --confirm

# Optimize tokens
ichiro-mind optimize
```

### Experience Replay
```python
# Before making similar decision
similar = mind.get_lessons(context="database_choice")
# Returns past decisions and outcomes
```

### Entity Tracking
```python
# Track evolving entities
mind.track_entity(
    name="兵步一郎",
    type="person",
    attributes={
        "role": "creator",
        "interests": ["AI", "automation"],
        "preferences": {"ui": "minimal", "docs": "bilingual"}
    }
)

# Update entity
mind.update_entity("兵步一郎", {"last_contact": "2026-03-07"})
```

## 🔌 MCP Integration

Add to `~/.openclaw/mcp.json`:

```json
{
  "mcpServers": {
    "ichiro-mind": {
      "command": "python3",
      "args": ["-m", "ichiro_mind.mcp"],
      "env": {
        "ICHIRO_MIND_BRAIN": "default"
      }
    }
  }
}
```

## 📊 Performance

| Operation | Latency | Throughput |
|-----------|---------|------------|
| HOT recall | <10ms | 10K ops/s |
| WARM recall | ~100ms | 1K ops/s |
| COLD search | ~50ms | 500 ops/s |
| ARCHIVE read | ~200ms | 100 ops/s |
| Store memory | ~20ms | 5K ops/s |

## 🎯 Use Cases

1. **Long-running projects** — Never lose context across sessions
2. **Complex decisions** — Track decision trees and outcomes
3. **User relationships** — Remember preferences, history, quirks
4. **Error prevention** — Learn from mistakes, suggest alternatives
5. **Knowledge accumulation** — Build up domain expertise over time

## 🧠 Philosophy

> *"Memory is not storage — it's intelligence."*

Ichiro-Mind treats memory as a first-class citizen:
- Memories have relationships
- Memories evolve over time
- Memories compete for attention
- Memories decay when unused
- Contradictions are resolved
