Independently verified via direct fetch of both cited sources. Congress.gov confirms H.R.5704 (118th Congress, 2023-2024): 'Protecting Student Athletes From Concussions Act', sponsored by Rep. Mark DeSaulnier [D-CA10], introduced Sept. 26, 2023, and 'Referred to the House Committee on Education and the Workforce' -- it did not become law. GovTrack corroborates the same sponsor, introduction date, and 'Introduced' status. DeSaulnier is the lead/primary sponsor of the bill that matches the promise directly (it promotes state requirements for schools on concussion prevention and treatment, the mechanism being conditioning federal education funding on states adopting concussion-safety laws). Because he actively led and sponsored the measure -- well beyond a single supporting vote -- but it was not enacted, CHAMPIONED (+0.75) is correct rather than FULL. Fairness check: a lead sponsor of either party whose named bill is referred to committee and dies without enactment earns CHAMPIONED under the same standard. (Trimmed two unverified specifics from the prior rationale -- a named R-MN cosponsor and a 119th-Congress reintroduction bill number -- as neither was independently confirmed and neither is load-bearing for the outcome.)
