Another name this product answers to — a distributor pricelist's row name, the name printed on this product's box, a name an old catalogue traded under, a model's street name in real speech (PS5 for the PlayStation 5). A product carries as many of these as it has names; each is plain text, and each must be a name the product actually trades or traded under — attestable on a pricelist, a box, a catalogue, or in real speech. Search keywords and seller-private feed labels are not names and stay out of scope. Kind- and brand-level synonyms are not homed here either: those belong on the kind or brand token's own labels (a Swahili word for the bucket kind is the kind's label, not this product's alias) — this word applies the label model one stratum down, to names of THIS product. Distinct from display name, the one preferred name a listing leads with: also-known-as never replaces it, it is the name set behind it, so the product stays reachable by every name it genuinely traded under. Distinct from model name (the maker's model designation) and from trade identifier (machine codes on a scheme, not human names). The pool declares the slot; the realised name strings are the data layer's instances. A search index built over these names is presentation derived from them — the names themselves are registered facts, not derivable from anything else.
