Li'nage is a custom-built version control system that tracks the history of individual lines rather than whole files — giving far deeper insight into how code evolves over time.

Built in C# with a four-layer clean architecture (Presentation → Controllers → Core → Infrastructure), it implements:

• Pluggable diff algorithms — Myers (O(ND)), Patient (long files), and Minimal (O(N log N))
• AI-assisted commit tracking — detects and surfaces AI-generated contributions
• Multi-protocol authentication — HTTP/HTTPS tokens, SSH keys, and OAuth
• Visual commit graph — interactive DAG visualization of branch history
• Snapshot-based recovery — cryptographic integrity checks via SHA-256, rollback to any state
• Secure credential storage — AES-256 encrypted via Windows Credential Manager

Data is persisted in SQLite for metadata and NTFS for file storage.
