## What Makes This Documentation Unique

### 1. Line-Level Precision

Unlike typical documentation, every code reference includes:
- Exact file path relative to repository root
- Specific line numbers or line ranges
- Context about what the code does
- Why it matters to the system

Example:
```markdown
// Lines 347-401 in shared.go
func (r *SharedRuntime) initializeElectionSystem() error
```

### 2. Implementation Honesty

Documentation explicitly marks:
- **What's Production:** Tested and deployed
- **What's Beta:** Functional but evolving
- **What's Stubbed:** Interface exists, implementation TODO
- **What's Experimental:** Research features
- **What's Deprecated:** Scheduled for removal

No "coming soon" promises without status indicators.

### 3. Real-World Examples

All examples are:
- Runnable (not pseudocode)
- Tested patterns from actual usage
- Include error handling
- Show integration with other packages

### 4. Troubleshooting Focus

Every major package includes:
- Common issues with symptoms
- Root cause analysis
- Step-by-step solutions
- Prevention strategies

### 5. Cross-Package Integration

Documentation shows:
- How packages work together
- Data flow between components
- Initialization ordering
- Dependency relationships
