  "description": "Japanese car genealogy with sources. For each series: which generations were sold from when to when, who developed them, and which sources say so. Read-only. Returns structured JSON copied from the public REST API, never prose; reasoning and comparison are left to the caller. Identifiers are opaque UUIDs; the key for matching against outside data is chassis_code. An empty list means 'not researched yet', never 'none'. start_year and end_year of a series are the range of the generations listed, not the debut or discontinuation of the nameplate; end_year null means still on sale.",
