+# module: release
+
+职责:      放行与落地 —— 落地预检五项、动作意向登记、放行写合并、幂等落地、
+           落地失败卡、输出口发射
+不负责:    放行卡的卡协议与回传校验(见 human-tool)、草稿层与冲突检测的实现(见 ledger)、
+           工具执行的实现(见 toolbox)、终态命名(见 task)
+
+公开出口:  index.ts
+  - 类型:`ReleaseService` `PrecheckReport` `PrecheckFinding` `LandingVerdict` `LandOutcome`
+          `SubmitForReleaseInput` `SubmitOutcome` `DeliverableCheck` `CriterionCheck`
+  - 错误:`PrecheckFailedError` `DeliverablesMissingError`
+  - 端口类型:`IntentStore` `LedgerGateway` `ToolGateway` `CardGateway` `TaskContext`
+          `PortEmitter` `MemoryRecorder`
+  - 用例工厂:`createReleaseService(deps): ReleaseService`
+  - 纯函数:`landingVerdict` `missingDeliverables` `submittable` `summarize` `idempotencyKey`
+  - adapter:`createIntentStore`;Drizzle 表:`actionIntentTable`
+
+层级:      L4(编码规范 §4)
+依赖:      @contracts;@shared/db;port 注入:ledger(L1)、toolbox(L2)、human-tool(L3)、
+           event(L1,输出口发射)、memory(L2)
+被依赖:    loop-engine, flow-engine, task, app
+
+不变量(OS 7.3 / AM 12.1):
+  - **预检先于放行**:`submitForRelease` 预检不过即抛 `PrecheckFailedError`,**不发卡**
+  - **卡面即已验证的动作清单**:验收工单的 actions 只列预检通过的意向
+  - **必交付物缺一不得提交放行**
+  - **放行通过即刻落地**,每个动作附幂等键(任务 × 意向)—— 重放不重复触达世界
+  - **落地收敛,输出口才发射** —— 下游只见落地完成的任务;受阻时 `emittedPorts` 恒为空
+  - **已成动作留存不回滚**;残余失败走落地失败卡(执行工单的预置形态),不静默成功
+  - **落地受阻是运行态不是终态**:处置后仍收敛于终态名录
+  - 放行写经 `ledger` 出口的 `releaseWrite`,不自行碰台账(§12.5#9)
