# App 权限政策与 CI 工作流变更通道

适用对象：cloudbrid-agent App（AG-1）及未来任何自动化写仓身份。决策背书：
ADR-0045（.github issue #102）；机器执法：`governance/expected-state.json`
`github_app.must_not_have` + drift-check §6。

## 规则 1：App 永不持有 workflows / administration 权限

`workflows:write` 等于允许修改审判自己的 gate 定义（自动合并计划 #81 §3.3
的核心威胁模型）。App 是高频自动化身份，该权限面不可接受。GitHub 侧的
自然结果：App 创建的 tree 一旦包含 `.github/workflows/**` 即 403
（Resource not accessible by integration）——这是**预期行为**，不是故障；

2. 错误定位工作流 403 🐞 Bug ≡ Correctness

文档断言 App 创建包含 .github/workflows/** 的 tree 时立即返回 403，但 Git tree 创建只是写入 Git 对象，之后还需创建 commit 并更新
branch 才形成文件变更，因此不能把权限拒绝固定在 tree 创建阶段。这会误导 agent 对成功创建 tree 或后续 ref 更新失败的诊断。
Agent Prompt 
## Issue description
文档错误地断言只要创建的 Git tree 包含 `.github/workflows/**` 就必然立即返回 403；GitHub 的权限要求适用于访问或修改工作流文件，但拒绝发生在哪个 API 操作取决于实际写入路径。

## Issue Context
保留“App 不得拥有 Workflows: write”以及权限不足可能返回 `Resource not accessible by integration` 的政策结论，但不要把失败固定到 tree 创建操作。

drift-check §6 一旦发现 App 出现禁用权限即报漂移（应立即在 App 设置页移除）。

## 规则 2：CI 工作流变更走 owner 凭据通道

`.github/workflows/**` 的变更由 owner 凭据提交，两种形态：

1. **常态**：agent 在 issue/PR 描述中以 diff 形式产出补丁，owner 审后自行
apply 提交 PR；
2. **owner 显式授权的 agent 会话**：owner 以 PAT 授权 agent 代为提交
（先例：T-W5-034 回迁，AI_Web_School PR #51）——PR 留痕，审计面完整。

消除 PAT 例外与 AG-1 契约的冲突。

AGENTS.md Line 8 将 cloudbrid-agent GitHub App 定义为 agent 的写仓库身份，并规定令牌来源、单仓作用域和 1 小时有效期。本段却允许 owner 使用 PAT 授权 agent 提交，且没有同步更新该硬规则或限制 PAT 的安全边界。

请二选一：

  1. 删除 agent 使用 PAT 的例外，只保留 owner 手工 apply。
  2. 在 AGENTS.md 和本规范中明确该例外，并规定最小仓库权限、有效期、吊销方式、审计记录和禁止绕过门禁的条件。

否则两个治理文件会允许不同的写入身份。

1. owner pat bypasses approved token scripts 📘 Rule violation ⛨ Security

The new policy permits an owner to authorize an agent with a PAT without requiring scripts/ghcb or
scripts/gh-app-token.sh, and without requiring a fine-grained, short-lived, least-privilege
credential scoped to a single repository, securely injected and revoked after the session. A classic
or broadly scoped owner PAT could elevate the agent from a restricted App token to every repository
and API permitted by the owner’s credentials, enabling credential leakage or operations outside the
PR gate.
Agent Prompt 
## Issue description
The owner-authorization path permits an agent to use an unspecified PAT directly, bypassing the approved token-acquisition scripts and the existing App flow’s single-repository, least-privilege boundary.

## Issue Context
Agent GitHub operations must obtain credentials through `scripts/ghcb` or the legacy `scripts/gh-app-token.sh` with explicit repository scope. Retain the owner-applies-diff path, or document an approved-script-based, repository-scoped authorization mechanism; if PAT authorization remains, allow only short-lived, fine-grained, single-repository credentials with only the permissions needed to submit workflow changes, require secret-manager injection, prohibit logging or persistence, and revoke the credential immediately after the authorization session. Where supported, prefer auditable, expiring temporary authorization over a long-lived owner PAT.

通道约束：owner 凭据**不豁免任何机器门禁**——变更仍必须走 PR 过 gate +
ruleset（owner-merge 语义见 GOVERNANCE flows.governance_change）。

## 规则 3：agent 遇到工作流变更需求的动作序列

1. 产出完整 diff，登记到对应 issue/PR；
2. 声明「需 owner 凭据通道」（引用本规范 + ADR-0045）；
3. 等待 owner apply 或显式授权；**不得**尝试以 App 身份直推（403 且无意义），
**不得**因此绕过 PR 流程（如请求 owner 直推 main——那要走破玻璃流程）。
