Temporal Ownership Concentration Survey

Phase 1 surveyed temporal ownership concentration across multiple open-source repositories.

Key findings:

• Historical concentration can decrease as active subsystems attract broader participation.
• Emerging concentration signals can identify recently concentrated maintenance areas.
• Repository reorganizations can create false "no recent activity" signals.
• Current implementation has scalability limitations due to full-history parsing.

Supporting verification notes and methodological limitations are included in the repository.
