Conversation
Summary of ChangesHello @bestony, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! 这份拉取请求引入了一份新的待办事项需求文档，旨在为自驱流程变更建立灰度/金丝雀运行机制。其核心目的是通过小范围测试来验证自动化流程和脚本的变更，从而显著降低直接部署可能导致的大面积故障或成本异常的风险，提高自驱系统的发布安全性与稳定性。 Highlights

Reviewer: Product Manager
- Acceptance criteria are not testable: success率/运行时长/成本 thresholds and baseline comparison rules are unspecified, so teams can't verify pass/fail. Suggest adding concrete threshold examples and how baselines are computed.
- Scope boundary is vague: “关键自驱工作流” and “指定 workflow/时间窗口/样本比例” lack a clear selection rule or initial list, which risks inconsistent rollout. Suggest defining eligibility criteria or enumerating the first workflows to support.
- Manual override requirement is underspecified: “强制推广/回滚入口” doesn’t define where the control lives or required permissions, which is a product risk for audit/compliance. Suggest clarifying control surface (e.g., issue command, workflow dispatch input) and approver roles.

Code Review
The pull request introduces a new backlog document for workflow change canary rollout. The document is well-structured and provides a comprehensive overview of the requirement, target users, core scenarios, user problems, external research, proposed solution, priority & impact, and acceptance criteria. The metadata section is also complete. No critical issues were found.

- External research evidence section lists “内部历史数据（待补充）” without any concrete baseline numbers, yet acceptance criteria relies on baselines; add the last-90-day failure/cost/MTTR data or explicitly mark this requirement as blocked until data is filled.
- Canary qualification and approval process are referenced but not defined (e.g., who approves expansion, what is the workflow for “审批流程”); specify the exact approval actors and steps so scope boundaries and rollout governance are testable.
- Acceptance criteria require maintainer-only manual promote/rollback via workflow_dispatch or issue command, but the security/control mechanism isn’t specified; add explicit access control rules (e.g., GitHub permissions/label checks) to make this testable.

Reviewer: Product Manager
- “内部历史数据（阻断项，需补齐）”仍为空，且验收标准要求补齐后才能排期；当前需求文件缺少数据表/统计摘要或补齐计划，可能导致需求无法进入执行。建议补充数据样例或明确责任人/来源/时间，或把状态标为阻断并注明解锁条件。
- 基线定义要求“最近30天内稳定版本的最近7次成功运行”，但未说明不足7次或近期波动时的处理方式，可能导致阈值不可计算或偏差过大。建议增加最小样本与回退规则（如扩展窗口、使用上一个稳定版本基线或人工确认）。
- 灰度资格规则包含“高风险（如夜间合并）”但未量化或标注触发条件，审批人名单也仅示例说明；执行时容易出现判断不一致与权限争议。建议明确可审计的触发信号（标签/文件路径/时间窗）与审批名单存放位置。

Update Record 2026-02-21 16:22:10 +08:00
Update summary:
Add internal historical data requirement to quantify failures, cost variance, and recovery time for canary rollout thresholds.
Define rollout scope and eligibility rules, including initial workflow whitelist, risk criteria, and canary sampling/time-window approach.
Specify baselines for success rate, runtime (P95), and cost/API usage using recent stable runs.
Tighten acceptance criteria with explicit threshold values, baseline linkage, and restricted manual override controls.

Update Record 2026-02-21 16:24:53 +08:00
Update summary:
Expanded the internal historical data requirement into a blocking item with specific metrics, data sources, and ROI/baseline usage.
Tightened rollout scope to an explicit initial whitelist and added an approval process for adding new workflows.
Split acceptance criteria to separate the manual promote/rollback controls from the permission enforcement rules.
Added a requirement to define auditable permission sources (e.g., CODEOWNERS/allowlist) for manual overrides.
Added a requirement that internal historical data must be completed and reviewable before scheduling execution.
