落地 C143d Stage-5a+5b：EndpointParser 统一 scheme://host:port 解析（域名/容器名/Service 名/IPv4/IPv6 方括号）；MongoEndpointRegistry 写侧（D12 环境变量引导 + 出口探测回退 + TTL 索引 + 5s 心跳全量幂等 upsert + 优雅退出写 Stopped）；MongoEndpointWatcher 读侧（5s 轮询 + 三周期判活 + 双视图路由表原子替换 + Instance* 事件 + incarnation 判定）；MongoDiscoveryRemoteRoleRouter 实现 D3 case 2/3 真实转发 （TcpEnvelopeForwarder 标准帧 + envelope 字节契约），替换 C143c 占位。 Linear: GFX-851
GameApp 早期装配的占位路由缝由 MongoDiscoveryRuntime.Activate 在 控制库就绪后重装为真实实现：watcher 必启，心跳写侧仅在广播端口 已配置时启动；Activate 首调胜出幂等，多 Role 进程安全。 Linear: GFX-851
EndpointParser 全形态与 17 个结构性违规样例；路由器替身单测与 TcpListener 真实收帧验 wire 格式；Mongo 集成用例（环境变量门控， CI 侧真跑）覆盖心跳终态、发现摘除、incarnation 与 Draining 双视图。 Linear: GFX-851
filter 扩至 GameFrameX.Tests.Discovery，新增 mongo:7 service container 与连接串环境变量，让心跳集成用例在 CI 真跑。 Linear: GFX-851

📝 WalkthroughWalkthroughChangesMongo 动态发现与远程路由
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~60 minutes Change: Feature Merge Risk: 🟡 Moderate · up to 本次改动引入的动态服务发现层存在若干确认的缺陷：实例心跳在第一次写入后不再更新，健康实例会被误判下线；实例视图可能包含尚未就绪或已摘除的实例；IPv6 环境下发布的地址格式非法；进程在准备就绪前就对外宣告可用。这些问题目前不影响既有流量（尚无业务调用方使用跨进程转发），但应在合并前修复，否则该发现层上线后行为不可靠。 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@GameFrameX.NetWork.RemoteMessaging/Discovery/EndpointParser.cs`:
- Line 169: 在构造 ParsedEndpoint 前，为非 IP 主机名增加 DNS、容器名或 Service 名校验；拒绝空白及包含
/、?、#、@ 或 : 的值，并让这些输入在解析阶段立即失败。保持合法主机名继续按 EndpointAddressKind.DnsName 返回，定位并修改调用
ParsePort 的端点解析分支。
In `@GameFrameX.NetWork.RemoteMessaging/Discovery/MongoDiscoveryRuntime.cs`:
- Around line 112-113: 调整 MongoEndpointRegistry 的启动流程，避免 StartAsync 立即将实例发布为
Active：先发布 Booting，并在 MarkStartUpReady 或网络监听成功、服务真正就绪后显式切换为
Active。同步更新两个启动调用方，确保其他进程不会在业务数据库、组件和 Social TCP listener 就绪前发现该实例。
In `@GameFrameX.NetWork.RemoteMessaging/Discovery/MongoEndpointRegistry.cs`:
- Around line 362-365: Update the guard around the endpoint status write so
Active heartbeats never set _stoppedWritten and continue updating lastHeartbeat.
In the status-handling logic, use _stoppedWritten to make only Stopped writes
idempotent, returning early for repeated Stopped writes while preserving Active
writes until shutdown.
- Line 214: Update the endpoint construction in the relevant discovery method to
derive an authority host from addressKind, wrapping IPv6 advertiseHost values in
brackets unless already bracketed. Use that authority host in the tcp URI while
preserving IPv4 and existing bracketed inputs.
In `@GameFrameX.NetWork.RemoteMessaging/Discovery/MongoEndpointWatcher.cs`:
- Around line 354-365: 更新未知实例处理逻辑（_knownInstances、pendingEvents 及
descriptor）以与路由表准入条件一致：仅对非 stale 且状态不是 Stopped 的首次观测发送事件；首次观测为 Draining 时发送
Draining，其他具备路由资格的状态发送 Online，stale 或 Stopped 不发送 Online，并保持已有 incarnation
变化时的重启事件语义。
In `@GameFrameX.NetWork.RemoteMessaging/Discovery/RoleRouteTable.cs`:
- Line 105: Update FromInstances so instancesById only includes entries whose
Status is InstanceStatus.Active or InstanceStatus.Draining; exclude Booting,
Removed, and all other statuses while preserving the existing instance ID
mapping.
In `@GameFrameX.NetWork.RemoteMessaging/Routing/TcpEnvelopeForwarder.cs`:
- Around line 126-128: 在 TcpEnvelopeForwarder 的 ForwardAsync 写入流程中，为每个
endpoint/provider 增加专用写锁，并在同一临界区内串行执行 stream.WriteAsync 和 stream.FlushAsync；不要依赖
GetOrCreateStreamAsync 现有的获取锁，确保同一 endpoint 的完整帧不会交错写入。

在服务就绪后再发布 Active。
MongoEndpointRegistry.StartAsync 会立即 upsert Active。两个启动调用方都在业务数据库、组件和 Social TCP listener 就绪前执行 Activate。其他进程可以提前发现该实例并向尚未就绪的进程发送流量。
请先发布 Booting。在 MarkStartUpReady 或网络监听成功后，再显式切换为 Active。

非 IP host 在归类为 DnsName 前增加 DNS/容器名/Service 名校验： 空白及 /、?、#、@、: 等字符在解析阶段立即抛 EndpointFormatException， 避免 tcp://user@host:7777 这类输入延迟到连接阶段才失败。
修复 CodeRabbit 评审的四项发现层缺陷： - StartAsync 先宣告 Booting，新增 MarkActiveAsync/MarkActive，Game 与 Social 启动流程在 MarkStartUpReady 后才切换 Active，其他进程不会 在业务库、组件与监听就绪前收到本实例流量。 - 心跳守卫改为仅 Stopped 写入幂等：Active 心跳持续更新 lastHeartbeat， 健康实例不再被 watcher 三周期阈值误判下线。 - IPv6 广播地址在 authority 中加方括号， EndpointParser 不再拒绝 IPv6-only 环境发布的端点。 - watcher 首次观测事件与路由表准入一致：仅非 stale 且 Active/Draining 发事件（Draining 首观测发 Draining），RoleRouteTable Instance 视图 仅收 Active/Draining，Booting/Stopped/Removed 不参与路由。
每端点改为连接束（连接提供器 + 专用写锁），WriteAsync 与 FlushAsync 在同一写锁临界区内串行执行；提供器原有信号量只保护连接获取，并发 ForwardAsync 的帧字节不再交错破坏长度前缀。
