The eligibility window (most people assigned male at birth, ages 18 through 25) and the small registrant field set (name, date of birth, SSN, current mailing address, contact) were confirmed against the source; individual input fields reflect the form's structure but are not yet independently re-verified item-by-item. The age-eligibility window is a temporal rule v0.1 cannot encode and is recorded in field descriptions. Status remains 'draft'. See VERIFICATION.md."
