The Sartori Firm Index measures footprint and momentum (scale · reach · hiring), not practice quality. It never assigns an Atlas tier, and the Atlas never reuses this number — the two lenses are deliberately separate.

- —No firm-level numeric score exists; Atlas tiers apply only within their own market or practice.
- —No third-party legal-directory band is used as an input.
