This commit adds comprehensive X-Bow (XBEN) benchmark results demonstrating Shannon's performance across 104 CTF security challenges. Each test case includes detailed penetration testing reports and exploitation evidence for reproducible research. Contents: - 104 XBEN test case directories (XBEN-001-24 through XBEN-104-24) - Deliverables including analysis reports and exploitation evidence - Individual test case results with vulnerability assessments 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
