Transition context
- H-1B values are certified Labor Condition Applications, not visa approvals.
- Job postings are seed-static / seed-derived; treat as provider-ready proxy coverage until observed provider data is wired in.
- Transition matches are directional skill-overlap context, not placement guarantees.
- This release is a FutureGrid broad-SOC seed derived from public BLS ORS requirement concepts and categories, not direct occupation-level ORS survey estimates. It describes job requirements, not worker ability, AI capability, or displacement probability. Automation friction is a FutureGrid derived score and should be read alongside exposure, demand, wage, and projection signals.
