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：
- 删除 agent 使用 PAT 的例外，只保留 owner 手工 apply。
- 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.

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。

摘要
#102 政策选项 (2) 的文档落盘（决策=ADR-0045）：
standards/automation/app-permissions.md：①App 永不持有 workflows/administration 权限（威胁模型：workflows:write=可修改审判自己的 gate；机器执法已由 expected-state must_not_have + drift-check §6 承担）；②CI 工作流变更的 owner 凭据通道（常态=agent 产 diff→owner apply；owner 显式授权会话=先例 AI_Web_School PR#51；通道不豁免任何机器门禁）；③agent 遇工作流变更需求的动作序列。配套已落地：AI_Web_School PR #51 已合并（test-freeze 并入 gate.needs，回迁完成，T-W5-034 验收五条全绿——见 #102 关闭评论）。Closes #102
