governance: 拆除 required_review_thread_resolution 死锁（P1-2，ADR-0031） by randypanding · Pull Request #103 · Cloudbird-Software/.github

randypanding · 2026-08-20T04:17:32Z

摘要

自动合并计划 P1-2（#83，ADR-0031 已合入 agent-registry#46）。

本 PR 合并前刚刚被该死锁阻塞过一次：PR #100（P1-1）gate 全绿后被 BLOCKED——qodo/coderabbit 两条 bot 各留 2 条未解决 review thread + 活体规则 required_review_thread_resolution: true → 无人会去点 resolve。#81 §2.2 描述的定时炸弹今日在组织内首次实际引爆。

变更

main-protection.json：required_review_thread_resolution true → false（自动合并计划 #81 §2.2 推荐项；不采用 resolveReviewThread 自动清理——被审者关闭审计意见语义不可接受）
新增 standards/automation/bot-channels.md：机器意见只走 check run annotation / 普通 PR comment；禁止机器产生 review thread；禁止机器 resolve 人类 thread；机器不得自我授权

验证

T2 App token enable auto-merge 实测 ✅：agent-registry#45——App 创建 PR → gh pr merge --auto --squash 退出码 0 → auto_merge != null（enabled_by=cloudbrid-agent[bot]）→ gate 绿后无人触碰自动合并（组织首个全自动合并闭环）
T1 死锁消除端到端：待本 PR 合并 + apply.sh 应用后执行（当前活体规则仍为 true，需先落地）
T3 对账回归：合并后 apply.sh 应用 ruleset，drift-check §1 文本对账

合并后动作：跑 apply.sh §1 应用 ruleset → 在 Use-up-Plan 重演 T1（unresolved thread + auto-merge 合并成功）。

C1 声明：governance/ + standards/ 路径，ADR-0031 背书。

Summary by CodeRabbit

规则更新
- 调整主分支保护配置，不再强制要求解决所有拉取请求审查线程。
- 明确自动化反馈优先使用失败检查结论；单独的注释不会阻止合并。
- 细化自动化工具可使用的审查与评论形式，并限制相关 API 操作。
文档
- 新增自动化反馈通道规范，说明配置生效条件及应用流程。
- 更新规范索引，补充自动化反馈通道说明。

- main-protection ruleset: required_review_thread_resolution true→false （#81 §2.2 推荐项：无人值守下 unresolved thread = 永久 pending 定时炸弹） - standards/automation/bot-channels.md：机器意见只走 check run annotation / 普通 PR comment，禁止产生 review thread；不得 resolve 人类 thread；不得自我授权（为未来重启 thread 门 + reviewer agent 预置约束） App token enable auto-merge 实测已通过（agent-registry#45 全自动合并， P1-2 T2）。ruleset 应用待 apply.sh（admin token）。

本次变更将主分支保护规则中的审查线程解决要求设为禁用，并更新自动化反馈通道规范及其索引。

Changes

治理策略

Layer / File(s)	Summary
主分支保护规则更新 `governance/rulesets/main-protection.json`	将 `required_review_thread_resolution` 从 `true` 改为 `false`。
自动化反馈通道规范 `standards/automation/bot-channels.md`, `AGENTS.md`	规定机器否决通过失败的 check run conclusion 生效，并明确 annotation 不单独阻塞合并。文档细化禁止的 GitHub API 形态和 `COMMENT` review 限制。索引新增该规范文件。

解除自动合并的 review thread 死锁并规范 Bot 反馈通道

🐞 Bug fix ⚙️ Configuration changes 📝 Documentation 🕐 10-20 Minutes

AI Description

• 关闭 review thread 必须解决规则，消除无人值守自动合并死锁。
• 限制机器反馈为 check annotation 或普通 PR comment。
• 禁止机器处理人类意见、自我审批或绕过确定性检查。

High-Level Assessment

The following are alternative approaches to this PR:

1. 保留 thread resolution 并禁止 Bot thread

➕ 继续强制解决所有人类 review thread
➕ 保留较强的显式审计闭环
➖ 现存或第三方 Bot thread 仍可能永久阻塞合并
➖ 任何人类未解决意见都会破坏无人值守自动合并

2. 自动解决机器创建的 thread

➕ 可以保留 required thread resolution
➕ 能够清理已知 Bot 留下的阻塞项
➖ 被审机器关闭审计意见的语义不可接受
➖ 需要可靠识别作者和意见归属
➖ 增加高权限 API 与错误解决 thread 的风险

Recommendation: 采用本 PR 的组合方案：关闭 thread resolution 合并门槛，同时从源头禁止机器创建 review thread。该方案最符合无人值守自动合并目标，并通过 required checks 保留机器的 veto 能力，避免赋予机器解决意见或自我授权的权限。

1. ~~Bot policy is undiscoverable~~ ✓ Resolved 🐞 Bug ⚙ Maintainability

Description

bot-channels.md declares mandatory behavior for every app, workflow, and agent, but the root
AGENTS.md—the stated index for loading detailed rules—does not reference it. Agents can therefore
follow the published entry contract without loading the review-thread prohibition, leaving the
preventative control ineffective.

+适用对象：一切以机器身份在组织仓库产出反馈的自动化——GitHub App

Relevance

●●● Strong
Recent accepted findings consistently require governance documentation and control discoverability;
adding the missing index entry is deterministic.

Evidence

The new document says it applies to all machine identities and prohibits review-comment APIs, while
AGENTS.md says detailed rules are discovered through its on-demand index; that complete index
omits the new automation standard.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The new mandatory bot feedback policy is not discoverable from the repository's agent entry contract, so agents may never load or follow it.

## Issue Context
`AGENTS.md` describes itself as an index whose referenced details are loaded on demand, but its index contains no entry for `standards/automation/bot-channels.md`.

## Fix Focus Areas
- standards/automation/bot-channels.md[3-15]
- AGENTS.md[19-29]

ⓘ Copy this prompt and use it to remediate the issue with your preferred AI generation tools

Context sources

✅ Compliance rules (platform): 7 rules

Review mode: ⚖️ Balanced: This changes an active branch-protection rule and establishes governance constraints for automation; its behavioral and policy impact warrants a careful single-pass review, but the localized two-file change is not dense enough for extended review.

Tip of the day

💡 Did you know, you can copy the agent prompt from any finding and feed it to your IDE agent

仅将配置从 true 改为 false，合并前仍为 true，且必须在合并后运行 apply.sh 才会生效；不要表述为该条件已在 P1-2 中移除。
- Around line 10-15: 修正该规范中机器反馈通道的事实描述：明确 check run annotation 仅是附加输出，合并阻塞由 gate
check run 的整体 conclusion 决定，因此 workflow 必须设置失败结论。更新对 POST /pulls/{n}/reviews
的说明，区分仅提交 body 的 COMMENT review 与包含 comments 数组行级评论时产生的 review
