Inventory and vehicle_of_interest use condition new, used or cpo; trade_in uses excellent, good, fair or poor. Inventory requires an available, intransit or pending status, an identifier and updated_at. Out-of-stock units are omitted. Context schemas enforce these constraints. Prices are integers in whole units of currency (USD when omitted); mileage uses mileage_unit (mi when omitted). Neither country nor request context overrides these per-vehicle defaults. price includes mandatory dealer charges and excludes only government-required consumer charges; fee itemizations are already included. Optional vehicle_type defaults to car; motorcycles, trailers, RVs and other units use relevant fields only. Electric range, battery and charging fields apply across vehicle types.

This is the discriminator that scopes which of the remaining fields are meaningful. OPTIONAL and defaults to `car` when absent, so existing car integrations remain valid without change.

For inventory listings and vehicle_of_interest use one of `new` | `used` | `cpo` (Certified Pre-Owned). For trade_in use one of `excellent` | `good` | `fair` | `poor`.

When `price` is present, every listed amount is already included in `price`; consumers MUST NOT add these amounts again. Omitted means the itemized breakdown was not provided and does not invalidate an otherwise authoritative `price`. An empty array means the publisher affirmatively reports no mandatory dealer charges. When present, a non-empty array is the complete vehicle-specific list. This array never represents a delta from rooftop fees: consumers MUST NOT join or merge it with `dealer.information`; when vehicle fees differ from rooftop defaults, this array replaces the rooftop array in full.
