Checks whether an item's information is sufficient to confidently classify it, BEFORE committing to a classification result. Internally requests the real classification candidates (6-digit subheadings, and — when shipToCountry is given — the country-specific tariff lines within each subheading) and determines whether the supplied text disambiguates them. Returns a readiness status the caller applies their own policy to (e.g. ask the user for more detail, or proceed to classify). Still does not classify the item and does not return an HS code — only the readiness status and, if not fully ready, a list of clarifications that would help.
