## Overview

This reference document explains how nWave documentation is organized using the **DIVIO (Diataxis) Framework**, which ensures that each document serves one primary user need and has maximum usability.

## DIVIO Framework (Four Types)

Documentation is organized into exactly four types:

### 1. **Tutorial** (Learning Orientation)
- **User Need**: "Teach me"
- **Purpose**: Enable newcomers to achieve first success
- **Key Characteristic**: Step-by-step guided experience with no assumed knowledge
- **Success Criteria**: User gains both competence AND confidence
- **Example**: Installation guide for a new user

**nWave Tutorials**:
- `docs/guides/tutorial-first-feature.md` - Build a feature end-to-end
- `docs/guides/installation-guide.md` - Installation instructions
- `docs/guides/jobs-to-be-done-guide.md` - Workflow orientation

### 2. **How-to Guide** (Task Orientation)
- **User Need**: "Help me do X"
- **Purpose**: Help user accomplish a specific, measurable objective
- **Key Characteristic**: Focused, step-by-step path to completion
- **Success Criteria**: User completes the task successfully
- **Assumes**: User has baseline knowledge; needs goal completion

**nWave How-to Guides**:
- `docs/guides/invoke-reviewer-agents.md` - Request peer reviews
- `docs/guides/how-to-deliver-wave-step-scenario-mapping.md` - Execute DELIVER wave with step-to-scenario mapping
- `docs/guides/troubleshooting-guide.md` - Solve common issues

### 3. **Reference** (Information Orientation)
- **User Need**: "What is X?" / "How do I look up Y?"
- **Purpose**: Provide accurate lookup for specific information
- **Key Characteristic**: Structured, concise, factual entries
- **Success Criteria**: User finds correct information quickly
- **Assumes**: User knows what to look for

**nWave Reference Documents**:
- `docs/reference/nwave-commands-reference.md` - Commands and agents
- `docs/reference/reviewer-agents-reference.md` - Reviewer specifications
- `docs/reference/step-template-mapped-scenario-field.md` - Step template schema with scenario mapping field
- `docs/reference/des-orchestrator-api.md` - DES execution coordination API
- `docs/reference/wave-command-output-paths.md` - Output path specifications

### 4. **Explanation** (Understanding Orientation)
- **User Need**: "Why is X?" / "How does Y work?"
- **Purpose**: Build conceptual understanding and context
- **Key Characteristic**: Discursive, reasoning-focused prose
- **Success Criteria**: User understands design rationale
- **Assumes**: User wants to understand "why"

**nWave Explanations**:
- `docs/guides/how-to-deliver-wave-step-scenario-mapping.md` - Step-to-scenario mapping in DELIVER wave
- `README.md` - Project entry point and quick start

```

## File Naming Convention

All documentation files follow **kebab-case** naming:

✅ **Correct**:
- `invoke-reviewer-agents.md`
- `how-to-deliver-wave-step-scenario-mapping.md`
- `nwave-commands-reference.md`

❌ **Avoid**:
- `HowToInvokeReviewers.md` (PascalCase)
- `how_to_invoke_reviewers.md` (snake_case)
- `HOW-TO-INVOKE-REVIEWERS.md` (UPPERCASE)

---

## Document Classification

### Type Purity Standard

Each document should be **≥80% a single type**:

| Type | Purity Target | Example |
|------|---------------|---------|
| How-to | >90% | Step-by-step task completion |
| Reference | >95% | Lookup tables, API specs |
| Explanation | >85% | Conceptual understanding |
| Tutorial | >90% | Learning from zero knowledge |

### What NOT to Do (Collapse Patterns)

❌ **Don't mix How-to + Reference in same document**
- Reference: "Parameters for the function"
- How-to: "Steps to call the function"
- Solution: Split into separate documents

❌ **Don't teach fundamentals in How-to guides**
- Problem: "Before you do this, let me explain what X is..."
- Solution: Link to Tutorial or Explanation, assume knowledge

❌ **Don't include task steps in Explanations**
- Problem: "Now you should: 1. Create X, 2. Run Y..."
- Solution: Move steps to How-to guide

❌ **Don't add narrative prose to Reference entries**
- Problem: "This is probably the most important function..."
- Solution: Keep Reference factual, move opinion to Explanation

---

## Cross-Reference Pattern

Documents link to each other following DIVIO principles:

### How-to → Reference
```markdown
For detailed reviewer specifications, see the [Reviewer Agents Reference](./reviewer-agents-reference.md).
```

### How-to → Explanation
```markdown
To understand why this approach works, see the relevant explanation document.
```

### Reference → How-to
```markdown
For usage examples, see [How to Invoke Reviewers](../guides/invoke-reviewer-agents.md).
```

### Explanation → How-to
```markdown
To get hands-on with this concept, see [How to Invoke Reviewer Agents](../guides/invoke-reviewer-agents.md).
```

---

## Version Tracking

All primary documentation files include version tags for synchronization:

```markdown
<!-- version: 1.4.0 -->
```

This ensures documentation stays in sync with code through pre-commit validation.

---

## Quality Standards

### Readability
- Target: 70-80 Flesch Reading Ease
- Checked with: Flesch-Kincaid Grade Level tools
- Entry points like README.md may be slightly lower (65-72) due to code examples

### Accuracy
- All code examples are executable/accurate
- All CLI commands verified to work
- All version numbers current

### Completeness
- Each document covers its intended scope
- Related topics cross-referenced
- No orphaned content

### Consistency
- Terminology consistent across documents
- Formatting follows same patterns
- Header hierarchy consistent

### Correctness
- Zero spelling errors (validated)
- Zero broken links (validated)
- YAML/JSON examples valid

### Usability
- Documents serve single primary user need
- Navigation is clear and intuitive
- Type purity maintained (≥80% single type)
