补齐 B5 前端 PlanningEditor 依赖的 meta-projection 真实化(此前 ContentMetaFacade 仅 unavailable stub): - meta-api 新增 MetaProjectionQueryApi + MetaSchemaProjectionDTO + MetaProjectionFieldDTO(projectionKey≡schemaKey)。 - meta-server MetaProjectionQueryApiImpl(@Service):schemaId→activeVersionId→MetaFieldDO 字段+MetaVisibilityPolicyDO 版本级可见性,policy 缺失兜底可见可编辑,enumValues JSON 解析。 - content RealContentMetaFacade(@Service 替换 Unavailable):work targetType 匹配多 active schema 列投影,经 meta-api 拿字段+可见性,读本域 planning 按 fieldKey 回填 value,fail-closed;validate 暂 default(B5 走 PUT planning 后端校验)。 验证:MetaProjectionQueryApiImplTest 4/4、RealContentMetaFacadeTest 5/5、BcBoundaryArchTest 2/2(0 跨 BC 违例)。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
