XiHan.Framework.Workflow.InMemory

内存工作流默认实现（Ring 3，role: default，RFC-0021）：提供 workflow.execution@1。

类型 用途
InMemoryWorkflowFeature 装配存储、实例锁与引擎，启动时起 DueBookmarkPoller 的循环（应用不在服务状态的周期什么也不做、不记告警），停止时等进行中的轮询结束
InMemoryWorkflowDefinitionStore / InMemoryWorkflowInstanceStore / InMemoryWorkflowBookmarkStore 有界内存表，按分区（平台 / 租户）存放，互不可见；保存与返回都是深拷贝（读己之写）；容量满 → WORKFLOW_UNAVAILABLE_002
InMemoryWorkflowTransaction IWorkflowTransaction：在调用里即可加入；没有事务，写入立即生效、调用回滚不撤销；只读的调用（操作契约只读）里写入在取锁、执行活动之前以 PERSISTENCE_UNEXPECTED_001 拒绝，与数据库实现相同，没装持久化也一样（ADR-0099）
InMemoryWorkflowInstanceLock 每个实例一个进程内信号量，没人用时回收；等待超时 → WORKFLOW_TIMEOUT_001
InMemoryWorkflowOptions XiHan:Workflow:InMemory：MaxDefinitions（1000）、MaxInstances（10000）、MaxNodeInstances（100000）、MaxBookmarks（100000）、PollIntervalSeconds（1）、BatchSize（100）

引擎选项在 XiHan:Workflow（MaxNodeExecutionsPerBurst、MaxSubWorkflowDepth、LockTimeoutSeconds、NotResumableBackoffSeconds、ExpressionCacheSize、RetentionDays、HousekeepingIntervalSeconds、HttpTimeoutSeconds），见 Workflow.Abstractions。两处选项的值写错都在启动时抛出。

单进程：实例锁与轮询只在本进程内有效，多实例部署换 Workflow.Database（租约行实例锁、领导节点轮询）。非事务：业务回滚不撤销引擎写入，要求"写申请并发起流程"原子的应用换 Workflow.Database。列表排序在内存里做，文本按序数比较、状态按生命周期的先后（ADR-0103）、空时间当作最小（数据库实现按列的排序规则与库的空值规则，ADR-0102）。通过 Workflow.Conformance 全部用例（事务相关的用例以 JoinsCallerTransaction = false 断言，只读调用的用例与数据库实现同一断言）。特性另登记持久化的消息目录（PersistenceMessages.Catalog），只读拒绝的消息在没装持久化的宿主上也能翻译。

依赖方向

依赖 XiHan.Framework.Workflow.Abstractions 与 XiHan.Framework.Persistence.Abstractions（只读拒绝的错误码与消息键）。被 Profiles.Full 引用。

状态

P0：可用（Preview）。通过 Workflow.Conformance 的存储、引擎与任务全部用例；加内存持久化、内存消息与发件箱的宿主也通过引擎与任务全部用例（ADR-0096 第六节）。
