State noxious-weed seed designations are material-scoped and never become non-seed plant restrictions, ecological-invasive findings, nursery restrictions, alternatives, product evidence, or fire votes. Introduced/established context is not an invasive warning. Minimum-only hardiness has no inferred maximum; canonical source-temperature conversion is validated and contradictory applicable rows project no primary zone. L48 context applies only to conterminous states and is never exact-state status. Fire-performance conditions are not maintenance advice. FEIS fire-ecology context does not vote in the plant classification. Absence of a status row is not regulatory clearance."}
