feat: 红队修复——全部 job timeout 熔断 + README 权限模型/风险声明（ADR-0013）

[randypanding]

Resolves #4（P1-2 修复；P1-1/P1-3/P1-4/P1-5/P2 复核处置说明）；ADR：agent-registry#10（ADR-0013）。

复核结论（issue #4 逐项）

项	结论	处置
P1-1 verifier 未实装	属实（产品仓侧无 verifier workflow）	注册层已声明（agent-registry checks.yaml test-tree-freeze active）；产品仓判卷 workflow 属 ADR-0010 二期（与 pr-identity-path-matrix 同批）——当前无业务仓消费，提前实装无消费方可验证。README 显式声明状态，不虚构已实装
P1-2 无 timeout	属实	全部 7 job 增加 timeout-minutes（gate=5/check=15/hygiene=10/dep-review=10/release=20/scorecard=10）
P1-3 workflow 覆盖 org 默认	复核为不成立	can_approve_pull_request_reviews 是 org 级 API-only 设置，workflow YAML permissions: 无法表达也无法覆盖（expected-state 固定 false）。pull-requests: write（dep-review）≠审批权，仅评论。README 权限模型表逐项声明
P1-4 单点故障	属实但架构固有	缓解=本仓 main 受 org ruleset（PR+squash+gate required+owner review）+ GitHub 90 天恢复窗口；不设镜像仓（双维护>收益）。README 声明
P1-5 通配+无 pin	属实设计权衡	本仓变更属 C1（owner-only review）；README 提供可选 sha-pin 路径（高敏感仓自选）
P2 automerge 判定	属实	判定逻辑在 template-service 仓；依赖审批 approver+SLA 已随 .github PR#19 定义（languages.yaml#dependency_policy）

变更

• 6 个 workflow 文件：7 个 job 全部加 timeout-minutes（熔断上限，非目标值）
• README：权限模型表（逐 workflow 显式权限+理由）、已知风险与缓解（单点/通配/verifier 状态/automerge 归属）

验证

• 全部 workflow YAML 解析通过；本仓 CI（ci.yml 自测）将随 PR 运行验证

Warning

Review limit reached

@randypanding, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 32 minutes

Limit details: You’ve used all 3 included reviews currently available.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

Add workflow timeouts and document CI security controls

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

AI Description

• Bounds all seven GitHub Actions jobs with workload-specific timeout safeguards.
• Documents least-privilege permissions and clarifies organization-level approval controls.
• Records accepted supply-chain risks, mitigations, and deferred verifier ownership.

High-Level Assessment

The PR uses GitHub Actions’ native per-job timeout control, which is the direct and reliable way to stop stalled jobs. Workload-specific limits are preferable to a uniform value because checks and releases have materially different expected durations; automated linting could prevent future omissions but would complement rather than replace this approach.

check.ymlBound reusable checks to 15 minutes +1/-0

Bound reusable checks to 15 minutes

• Adds a 15-minute timeout to the configurable setup, lint, and test job. This prevents consumer-specific checks from occupying a runner indefinitely.

Add timeouts to repository hygiene and gate jobs

1. Zero-permission default claim false ✓ Resolved 🐞 Bug ⚙ Maintainability

Description

The README says every workflow has top-level permissions: {}, but ci.yml grants contents: read
and scorecard.yml uses permissions: read-all. Although their jobs may still have appropriate
effective permissions, the new audit documentation does not describe the repository's actual
defaults.

Code

README.md[18]

+每个 workflow 顶层 `permissions: {}`（零权限默认），job 级显式声明最小必要权限：

Evidence

The two workflow files directly contradict the added statement: CI declares top-level `contents:
read, while Scorecard declares top-level read-all`.

.github/workflows/ci.yml[11-17]
.github/workflows/scorecard.yml[9-19]

Agent prompt

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

## Issue description
Update the permission-model introduction so it accurately distinguishes workflows using a zero-permission top-level default from CI and Scorecard, which declare different top-level permissions.

## Issue Context
Job-level permission blocks can narrow effective permissions, but they do not make the README's claim about every workflow's top-level declaration true.

2. PR write privilege understated ✓ Resolved 🐞 Bug ⛨ Security

Description

The README incorrectly says pull-requests: write only permits comments or labels; that permission
also authorizes pull-request review operations, whose API supports APPROVE and REQUEST_CHANGES.
The separate organization setting may currently prevent Actions-generated approvals, but it does not
narrow the token permission itself, so this documentation understates the workflow's capability if
that setting changes.

Code

README.md[27]

+`can_approve_pull_request_reviews` 是 org 级 API-only 设置（expected-state.json#actions_policy 固定 `false`）——workflow YAML 的 `permissions:` 块**无法表达也无法覆盖**该设置；本仓无任何 workflow 具备批准 PR 的权限路径。`pull-requests: write` ≠ 审批权（仅评论/标签类写操作）。

Evidence

The dependency-review job grants pull-requests: write; configuring the current action to post a
failure summary describes its usage but does not reduce the token's granted permission. GitHub
documents that the pull-request review API can submit APPROVE, REQUEST_CHANGES, or COMMENT
reviews.

.github/workflows/dep-review.yml[11-26]
🌐 GitHub's pull-request review API creates and submits reviews with APPROVE, REQUEST_CHANGES, or COMMENT actions.

Agent prompt

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

## Issue description
Correct the permission model's statement that `pull-requests: write` is limited to comments and labels. Explain that the permission enables pull-request write/review APIs, while the separate organization-level Actions setting currently prevents workflow-generated approvals.

## Issue Context
The dependency-review job grants `pull-requests: write` for its configured summary comment, but the granted token capability is broader than that action's intended use.

## Fix Focus Areas

Review mode: ⚖️ Balanced: This changes shared GitHub Actions workflow behavior and release/security-related controls across all consuming repositories; the edits are simple, but the broad CI blast radius and permissions/timeout semantics warrant a careful single-pass review.
