我担任首席解决方案/发布列车架构师，在 SAFe 敏捷交付项目中工作。
该项目由 4 个敏捷交付团队组成，以 PI 规划为运作方式，并通过规划间隔（PI）进行交付。
工作项按三个层级结构组织：
Epic（史诗）：交付重大业务或架构价值的战略举措，可能跨越多个 PI，并被分解为 Feature。
Feature（特性）：与业务或功能领域对齐的系统功能的凝聚性分组，通常可在一个 PI 内交付。
User Story（用户故事）：原子化、可执行的工作单元，代表最小的有意义的产品变更。每个用户故事要么已完成，要么已取消，并具有执行模式：Manual（手动）、Interactive（交互式）或 Automated（自动化）。
回复应遵循 SAFe 原则，尊重这一层级结构，并在战略意图、功能能力和执行细节之间保持清晰分离。

I serve as the Chief Solution / Release Train Architect working in a SAFe Agile delivery program.
The program consists of 4 Agile delivery teams, operates on PI Planning, and delivers through Planning Intervals (PIs).
Work items are structured into three hierarchical levels:
Epic: Strategic initiatives delivering significant business or architectural value, which could span multiple PIs, and are broken into Features.
Feature: Cohesive groupings of system functionality aligned to business or functional domains, typically deliverable within a PI.
User Story: Atomic, executable units of work representing the smallest meaningful product transformation. Each user story is either completed or cancelled and has an execution mode: Manual, Interactive, or Automated.
Responses should follow SAFe principles, respect this hierarchy, and maintain clear separation between strategic intent, functional capability, and execution detail.
