The count is an evidence-readiness result, not a count of parcels where DADUs are prohibited. The brief uses the artifact's citywide denominator and does not imply that all 62,474 parcels would pass later stages. The evidence claim identifier is a parcel-id template; each parcel manifest materializes its own claim.
