// @ts-nocheck
/**
 * A 401/403 from a provider that has no token to refresh must not start a refresh.
 *
 * The no-auth OpenCode connection carries no credentials, so every refresh attempt
 * fails after three retries (several seconds), and five failures open the
 * provider-wide refresh breaker for 30 minutes with "needs re-authentication". A
 * refusal that is scoped to the request (same verdict from every account) never
 * indicates a stale token either, keyed connection or not.
