## 🧠 Architecture

```
User Input → Intent Classification → Framework Selection

Purpose Detection (learn/understand/transform/decide/reference/inspire)

## 📦 Nonfiction Purpose System

The nonfiction pipeline uses **Purpose × Structure** classification:

### Reader Purposes

1. **LEARN_HANDS_ON** — Reader wants to DO something (tutorials, how-to)
2. **UNDERSTAND** — Reader wants to GRASP a concept (explanations)
3. **TRANSFORM** — Reader wants to CHANGE themselves (self-help, memoir)
4. **DECIDE** — Reader wants to MAKE A DECISION (business, analysis)
5. **REFERENCE** — Reader wants to LOOK UP info (manuals, documentation)
6. **BE_INSPIRED** — Reader wants to FEEL motivated (stories, manifestos)

### Framework Selection

The system automatically selects the best framework based on:
- Explicit flags (`--purpose`, `--category`)
- Keyword classification from concept
- Content analysis (for existing blogs/articles)
- Conversational Q&A (when ambiguous)

## 🔄 Checkpointing/Resume

Long generations can fail. Use checkpointing to resume:

```bash
# First run - saves checkpoint
opus generate --concept "My book" --thread-id my-book-001
# If it fails...

# Resume from checkpoint
opus generate --concept "My book" --thread-id my-book-001 --resume
```

## 🤖 Multi-Agent Systems

Opus supports three orchestration backends:

1. **LangGraph** — State machine with checkpointing
2. **CrewAI** — Sequential agent crews
3. **AutoGen** — Multi-agent debate/critique
