Suggested labels: Merge Risk: 🟠 High · up to The restored enforcement job can use a mutable workflow, policy, or script reference because it lacks the required fail-closed SHA validation, allowing the suppression budget check to run with unintended logic or thresholds. This is a high-impact merge-readiness risk that should be fixed before merging. 🚥 Pre-merge checks | ✅ 1 | ❌ 1❌ Failed checks (1 warning)

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
严重级别：高 — 在此 job 内先校验 ciw-ref。
check job 的 SHA 校验与 suppression-budget job 没有 needs 依赖。它无法阻止 Line 120 从分支、标签或其他可变 ref 检出检测器和 policy。这样会使自测和执法使用非固定版本，并破坏 workflow、policy 和脚本同 ref 的约束。
请在此 checkout 前添加相同的 40 位 SHA fail-closed 校验。

1. Pr api权限不足 🐞 Bug ☼ Reliability
suppression-budget job 只声明了 contents: read，但却用 gh api 访问 pulls endpoint 拉 diff/正文；在显式 permissions 下未声明的权限会被置为 none，导致该步骤可能直接 403 失败并让门不可用。应显式添加 pull-requests: read（以及需要时的附加只读权限）。
Agent Prompt
### Issue description
`suppression-budget` job sets job-level `permissions` to only `contents: read` but then calls the Pull Requests REST API via `gh api`.
When you specify any permissions, unspecified ones become `none`, so the token may not be allowed to read PR resources and the job can fail with 403 / “Resource not accessible by integration”.
### Issue Context
The failing step is the one that runs `gh api "repos/$REPO/pulls/$PR_NUM" ...` to fetch the raw diff and PR body.
### Fix Focus Areas
- .github/workflows/check.yml[94-99]
- .github/workflows/check.yml[137-149]
### Suggested change
Add job permissions:
```yaml
permissions:
contents: read
pull-requests: read
```
If later you add API calls that require more scopes, keep them explicit and read-only.

2. Ciw-ref未fail-closed校验 🐞 Bug ⛨ Security
suppression-budget job 直接用 inputs.ciw-ref checkout Cloudbird-Software/CI-Workflows，但未像 check job 一样校验其为 40 位 SHA；这会在 caller 误配（或未来演进）时破坏“检测器/脚本/policy 同 ref 钉源”的安全假设并引入供应链漂移风险。应在该 job 中复用同样的正则校验（或通过 needs 强制先过校验）。
Agent Prompt
### Issue description
`suppression-budget` checks out `Cloudbird-Software/CI-Workflows` using `ref: ${{ inputs.ciw-ref }}` but does not enforce that `ciw-ref` is a pinned 40-hex commit SHA.
This breaks the stated "pin same as caller uses" contract and removes fail-closed behavior for this job.
### Issue Context
The `check` job already contains a `校验 ciw-ref 钉源（fail-closed）` step; `suppression-budget` should apply the same guard before any checkout/run that depends on `ciw-ref`.
### Fix Focus Areas
- .github/workflows/check.yml[56-69]
- .github/workflows/check.yml[115-123]
### Suggested change
Add a step in `suppression-budget` (before the CI-Workflows checkout) mirroring the existing guard:
```yaml
- name: 校验 ciw-ref 钉源（fail-closed）
if: github.event_name == 'pull_request'
env:
CIW_REF: ${{ inputs.ciw-ref }}
run: |
if ! [[ "$CIW_REF" =~ ^[0-9a-f]{40}$ ]]; then
echo "::error::ciw-ref 必须为 40 位 SHA"; exit 1
fi
```
Optionally, also add `--depth 1`/fetch optimizations if desired, but keep the guard.

3. Pr diff可能被截断 🐞 Bug ≡ Correctness
suppression-budget 通过 pulls API 的 diff 媒体类型获取 pr.diff，但只校验“非空”；GitHub 对 PR/compare diff 有文件数与大小上限，超限时会部分展示/截断，从而让 suppression-budget 在大 PR 上漏检并错误放行。应检测截断条件并 fail-closed，或改用 checkout 后 base..head 的本地 git diff 生成完整 diff。
Agent Prompt
### Issue description
The job fetches `pr.diff` via:
`gh api "repos/$REPO/pulls/$PR_NUM" -H "Accept: application/vnd.github.diff" > pr.diff`
and only checks it is non-empty.
GitHub imposes diff limits (file count and raw diff size). When a PR exceeds limits, the returned diff can be incomplete, which would let this gate under-count suppressions and potentially pass incorrectly.
### Issue Context
This gate’s correctness depends on having a complete diff.
You already fetch PR JSON (for body). You can also fetch `.changed_files` and compare against the diff you received.
### Fix Focus Areas
- .github/workflows/check.yml[137-150]
### Suggested change (one acceptable approach)
1) Fetch `changed_files` (and optionally additions/deletions) from PR JSON.
2) Count files present in the diff (e.g., count `^diff --git ` headers).
3) If `changed_files > 300` OR counted headers < `changed_files` OR the diff contains known truncation markers, then **fail closed** with an actionable error.
4) Preferably, implement a fallback to a complete diff computed locally:
- Fetch base and head SHAs from the PR JSON.
- `git fetch` base/head (depth 1 is fine) and run `git diff <merge-base> <head>` (or `git diff base...head`) to generate a complete diff.
Keep the error message explicit: PR too large for API diff; split PR or use fallback.
