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:

// 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
