/**
 * tests/unit/quota-combo-cli-providers.test.ts
 *
 * Regression: qtSd/ combos were generated from PROVIDER_MODELS, which is
 * EMPTY for CLI/OAuth providers (codex, kimi, claude, …). A pool built from those
 * providers produced ZERO combos → the quota key saw no models. The fix reads the
 * provider REGISTRY (same source /v1/models uses), which has those providers.
 *
 * This test creates a "codex" pool and asserts syncQuotaCombos produces combos
 * (it would have produced none before the fix).
