# Tasks Calculations

> **Status: Historical compatibility pointer**

Task V3 已是 selected Target：

- [Task V3 Product / Domain Contract](/product-design/v3/tasks-feature/task-domain-lifecycle.md)
- [Task V3 Rollout 状态快照](/product-design/v3/tasks-feature/task-v3-rollout-status.md)

本页只保留 V2 inbound links，不再定义当前计算 contract。精确公式必须由 live code/schema 复核；deployment、TEST 与 PROD 状态以目标环境 evidence 和 rollout 快照为准。

Target contract 中的 [Lifecycle 与 UI projection](/product-design/v3/tasks-feature/task-domain-lifecycle.md#5-lifecycle-与-ui-projection)、[Funnel 与 Revenue projection](/product-design/v3/tasks-feature/task-domain-lifecycle.md#14-funnel-与-revenue-projection) 和 [Validation、testing 与 observability](/product-design/v3/tasks-feature/task-domain-lifecycle.md#17-validationtesting-与-observability) 不因写入文档就自动成为已部署事实。
