Manifest 格式

服务的 Manifest 是一份 JSON 文档（format 1）：它的限界上下文、上下文中的聚合及其命令与事件、订阅、框架的错误码，以及 $defs 之下每个载荷的 JSON Schema 2020-12。模块的片段（META-INF/wow/manifest/<module>.json）形状相同，只是没有 service。下面每个对象及其键的提纲，由写出它的代码 ManifestTree 生成；说明取自源码，为英文。

写出时省略的内容：

Absent optional values (a null description, unknown produces, derives, schedules or transformsTo, a fragment's service, a subscription's retry or job) are left out, not written as null, and so are a subscription source's nullableState and a command's mounted when false, an aggregate's ownership when it is OWNER, the default, and its retired events when it has none.
