what the source states: The bas-relief carvings on Hoa Hakananai'a are interpreted as a single composition that "narrates the island's birdman myth as recorded in the nineteenth" and early twentieth centuries.
what we infer: The comparison text for the Rapa Nui birdmen is ethnohistoric, recorded two to three centuries after the carving at the earliest; the study does not read the reliefs against any prehistoric text.

an honest empty state

This claim is in the ledger but not in the current edition's featured set. Nothing here has been assessed — that absence is information, not an oversight.

Still missing: plain-language gloss, credibility assessment, diagnosticity assessment, strongest objection, what would change our mind. A claim gains them when an edition features it and the edition's adopted assessment supplies the full treatment — a decision the panel reviews, not a field anyone flips.
