The partner ships a JSON list of model entries, each with an `id`, `tier`,
`scores` (per-category 1-10), and `cost` (1-10). This file does not ship the
registry data itself - it is loaded at runtime from a path supplied via the
PARTNER_REGISTRY_PATH environment variable, kept outside source control.
