## Data Methodology & Constraints for AI Agents
- **Exact Tenure Days**: Calculated as continuous days from official start_date to end_date (or today: 2026-11-13 if active).
- **Multi-Term Executives**: Leaders who returned for multiple distinct terms (e.g., Bob Iger at Disney, Sam Altman at OpenAI, Michael Dell at Dell Technologies, Howard Schultz at Starbucks) are evaluated by summing continuous days across terms while noting separate intervals.
- **Interim Term Separation**: Temporary interim appointments (such as Mira Murati at OpenAI or Colette Kress at Nvidia) are cataloged separately from permanent tenure leaderboards.
- **Verification Guarantee**: Every milestone date is corroborated against SEC EDGAR regulatory filings or official company press releases.
