Commit messages mentioning AI tools (Copilot, Claude, ChatGPT, etc.)\n   - Automated detection of AI-generated patterns\n   - Author self-identification of AI assistance\n   - Analysis of code style/pattern consistency with known AI outputs\n\n3. **Measurement Period**: All commits made between January 1, 2024 and December 31, 2026\n4. **Threshold**: Strictly greater than 30.0% of total commits\n5. **Verification Method**: Combination of automated analysis tools and manual verification by independent researchers\n\n**Calculation Method**:\n\n- Count commits containing any AI-generated code (not lines of code)\n- If commit contains both human and AI code, counts as AI-assisted\n- Exclude purely administrative commits (version bumps, config changes, etc.)\n- Include all branches that merged to main/master during the period\n\n**Edge Cases**:\n\n- If GitHub changes their starring system, use whatever equivalent \"top repositories\" metric exists\n- Repositories that become private or are deleted are excluded from analysis\n- Forks don't count separately -
