## [Unreleased]

### Fixed
* Utility 安全修复：配置凭据脱敏、解压炸弹上限、冲突异常 Secret 脱敏与压缩失败显式抛出（C433，GFX-1173，GitHub #919）：①`AppSetting.ToString/ToFormatString` 经浅拷贝掩码后序列化——`DataBasePassword`/`HttpSignSecret`/`InterNodeAuthSecret`/`HttpsCertPassword` 非空值输出 `***`（null/空串原样保留区分「未配置」），四个凭据不再随启动/停止日志明文外发；②`CompressionHelper.Decompress` 新增 `maxOutputLength` 上限重载（旧签名转发 const 默认 64MB），膨胀过程内超限即抛 `InvalidDataException`——Network `DefaultMessageDecompressHandler` 增构造参数上限、RemoteMessaging `IMessageCompressionAlgorithm.Decompress` 接口加参（const 默认值，源码兼容；`DefaultMessageCodec` 显式传 `_maxDecompressedSize`），事后长度检查降级为兜底防线，1MB 高压缩比帧不再可膨胀至 GB 级托管内存；③`SettingFieldConflict` 敏感字段判定扩展 Secret/Token 子串——多 Role 配置冲突异常不再明文携带 `HttpSignSecret`/`InterNodeAuthSecret`；④`RandomHelper` 类文档声明双随机源分级（基础接口 `Random.Shared` 非加密 PRNG 禁用于令牌/验证码/防作弊场景，安全场景用权重系列 CSPRNG 或 `RandomNumberGenerator`）；⑤落地已归档 C349 既定方案：`Compress` 异常原样抛出、`Decompress` 对非法/损坏/截断数据统一抛 `InvalidDataException`（含 SharpZipLib 截断流死循环主动判定），删除「失败静默返回原始字节」回退与 `CompressFailed` 本地化键；⑥`FP.Sqrt/Acos` 越界异常构造器实参换序（本地化消息进 `Message`、`"x"` 进 `ParamName`，修复前 `ParamName == null`）。公共 API 行为变更经本条披露；解压炸弹/脱敏/截断/参数名均有回归用例锁定。

更正接口变更的兼容性说明。

这里的“源码兼容”仅适用于通过接口调用 Decompress(input) 的代码。已有的自定义 IMessageCompressionAlgorithm 实现如果仍只定义单参数方法，就不再满足接口，重新编译会失败。请注明实现方必须增加 long maxOutputLength 参数；已编译的实现也需要重新构建。(raw.githubusercontent.com)

Review comment at @CHANGELOG.md at line 18:
更正 changelog 中关于 `IMessageCompressionAlgorithm.Decompress` 的兼容性说明：指出旧调用方通过
`Decompress(input)` 调用仍可兼容，但自定义实现必须增加 `long maxOutputLength`
参数才能重新编译，已编译的实现也需重新构建。

* 入队与定时撮合解耦（C406，GFX-1104）：删除每次入队的全量撮合及最新票据扫描，复用 `matchmaker-run` 按宿主调度节奏批量处理队列（默认 1000ms）。单轮撮合算法保持不变；桥测试覆盖四名玩家单批次形成两组及批次前取消不参与分配。
* 撮合通知异步执行与停用退订（C407，GFX-1105，GitHub #733）：`ICapabilityEventBus.Subscribe` 返回幂等 `IDisposable` 退订句柄（void → IDisposable 为二进制破坏性变更——包族消费方需重新编译；源码侧忽略返回值的既有调用不受影响）；online-match 模块撮合分配事件回调改为纯入队（移除同步总线回调内 `ResolveAssignmentAsync` / `session.WriteAsync` 两处 `GetAwaiter().GetResult()` 死锁面），新增 `match-assignment-notification-tick` 每轮有限批次（64）异步解析并推送（条目级失败不阻断同批其余条目，异常交调度器既有日志路径）；`DeactivateAsync` 停用收口——关闭入队、退订、清空待处理并等待在途批次完成，热更/停机后旧模块零通知。回归 13 例：总线退订契约 5 + 模块生命周期 8（含对旧同步实现确定性红的发布不同步解析 / 停用退订 / 停用清空 / 容错批次）。
