Source-led evidence
What this record can—and can't—confirm.
These are exact same-item joins from approved public sources. Conflicts and missing corroboration remain visible; offers are kept outside the evidence count.
Exact brand-and-model match between ENERGY STAR certification and an independent US DOE compliance filing. Market declarations and test results remain attached to their originating source.

Each value is attributed to the source that supplied it. An agreement is not a hands-on test; a conflict is not silently resolved; an absence is not filled by inference. Retailer offers are commerce data, and an absent recall does not confirm safety.
