Unlucky-Launcher/crates/core/tests/auth/microsoft_diagnostics.rs

//! M38：非 2xx 应答正文诊断（`AuthError::Response`）。
//!
//! 覆盖 MSA 真机验收里分不开的那几类：
//! - **JSON 403**：真实服务拒绝（服务端文案直出，引导查许可/区域）；
//! - **HTML 403**：网关/风控拦截页（引导查网络/代理，独立细分码 `*_non_json`）；
//! - **空体 403**：同样按「不确定」分流（`*_empty_body`）；
//! - 4xx / 5xx 各一，外加 XErr 优先级与 JSON 码的向后兼容。
//!
//! 失败日志（JSONL）与凭据红线在同一目录的 `auth_failure_journal.rs`。
