/**
 * Issue #2901 — OpenCode Free combo entries use the `opencode/` prefix instead
 * of `oc/`.
 *
 * The no-auth OpenCode provider has id "opencode" and alias "oc". The combo
 * builder built `qualifiedModel` from the provider *id* (`opencode/big-pickle`),
 * but `parseModel("opencode/...")` resolves to the **opencode-zen** provider
 * (an api-key tier) via a manual ALIAS_TO_PROVIDER_ID override — not the no-auth
 * "opencode" provider. The user-facing routing alias `oc/` resolves correctly
 * (`oc/big-pickle` → provider "opencode").
 *
 * This test drives the real builder against a fresh DB and asserts that no-auth
 * OpenCode models carry the `oc/` prefix.
