/**
 * #5477 — the combo builder's per-model option construction was extracted into a
 * shared `buildModelOptions` helper (one source of truth for the synced /
 * built-in / custom / fallback branches). This test drives the real builder and
 * locks the custom-model **source classification** branch: a custom model whose
 * stored `source` is one of api-sync/auto-sync/imported must surface as
 * `imported`, everything else as `custom`. A silent divergence in that mapping is
 * exactly what the extraction could introduce.
