严重：在算术扩展前校验 PR_LIVENESS_HOURS。

攻击者可将值设为 DRIFTS[$(…)]。DRIFTS 已在脚本中定义，因此该命令替换会在 LIVENESS_S=$(( LIVENESS_H * 3600 )) 中执行。作业环境包含 GH_TOKEN。

先拒绝非正十进制整数，再使用 10#$LIVENESS_H 计算秒数。

9. Check names split on spaces 🐞 Bug ≡ Correctness

Required contexts are extracted as newline-delimited strings but iterated with unquoted shell word
splitting. Any valid check name containing whitespace is broken into multiple names and falsely
reported missing.
Agent Prompt 
## Issue description
Required-check contexts containing whitespace are split into separate loop iterations, so the actual context can never match.

## Issue Context
Preserve each jq output line as one value by using a `while IFS= read -r ctx` loop or a Bash array populated with `mapfile`.

1. governance_token bypasses app identity 📘 Rule violation ⛨ Security

The new cross-repository pull-request and check-run queries use the generic organization-wide
GOVERNANCE_TOKEN instead of tokens obtained through scripts/gh-app-token.sh. This bypasses the
required cloudbrid-agent identity and single-repository token scope.
Agent Prompt 
## Issue description
The newly added GitHub API queries inherit an organization-wide token rather than obtaining single-repository tokens through `scripts/gh-app-token.sh`.

## Issue Context
The compliance rule requires authenticated automation to use the `cloudbrid-agent` GitHub App identity. The token helper requires `REPO` and issues a token limited to that repository, so the repository loop should obtain and use the appropriate token before making repository API requests.

6. Check runs omit later pages 🐞 Bug ≡ Correctness

Both new sections request only the first 100 check runs, so a required or stale run on a later page
is invisible. §12 can consequently report false missing drift, while §13 can report a PR healthy
despite an old pending run.
Agent Prompt 
## Issue description
The new check-run inspections only process page one and can miss required or stale runs beyond the first 100 results.

## Issue Context
GitHub caps `per_page` at 100 and exposes a `page` parameter. Fetch and validate all pages before drawing conclusions; any page failure must remain fail-closed.

4. Partial failures pass green 🐞 Bug ☼ Reliability

A failed check-runs query only produces drift when no later head contains the required context. If
another candidate succeeds, §12 exits green despite being unable to validate one candidate,
contradicting its fail-closed contract.
Agent Prompt 
## Issue description
§12 suppresses an API query failure when another candidate head contains the required check, allowing an incomplete validation to pass.

## Issue Context
`QUERY_FAIL` remains set, but the final failure branch also requires `FOUND == 0`; no drift is recorded when both are true.

3. Older pr masks missing check 🐞 Bug ≡ Correctness

§12 marks a required context live when it exists on any of the three selected PR heads, so completed
checks from older PRs mask its absence on the newest PR. A workflow job rename therefore remains
undetected until all three candidates no longer contain the old check name, defeating the intended
immediate liveness validation.
Agent Prompt 
## Issue description
Required-check liveness succeeds when any one of three PR heads contains the context. Historical checks on older PRs can therefore hide a missing required check on the newest PR.

## Issue Context
The script selects three heads and breaks after the first match, although the check is intended to detect a renamed job using the current PR head.

查询失败时始终记录漂移。

当一个 head 的 check-runs 查询失败、另一个 head 找到同名 check 时，QUERY_FAIL=1 且 FOUND=1。Line 477 和 Line 479 都不会调用 drift。脚本会以成功状态结束。这违反了本节声明的 fail-closed 行为。

7. Open prs truncated 🐞 Bug ≡ Correctness

§13 examines only the first 30 open PRs in each repository and still reports the repository healthy.
Repositories with more than 30 open PRs can therefore have stuck PRs that are never inspected.
Agent Prompt 
## Issue description
PR liveness only checks the first page of 30 open pull requests, leaving later open PRs unmonitored.

## Issue Context
Aggregate all pages before running the per-PR checks, and fail closed if any page cannot be fetched or parsed.

8. Dynamic ages defeat deduplication 🐞 Bug ⚙ Maintainability

The new drift messages embed continuously changing age values, but the workflow fingerprint
normalization only replaces the older 回填时限= format. A persistent stuck PR therefore gets a new
fingerprint and duplicate issue comment every hourly run.
Agent Prompt 
## Issue description
Liveness reports include changing second counts, causing the same persistent drift to produce a different issue fingerprint on every run.

## Issue Context
Extend fingerprint canonicalization to all new age message formats, or emit stable machine-readable drift identifiers separately from display details.

2. drift uses forbidden issue channel 📘 Rule violation § Compliance

The new PR-liveness alerts call drift, causing the workflow to publish machine feedback through
repository issues. The automation standard permits only failed check runs or ordinary PR comments,
so the configured issue-reporting channel is noncompliant for these new alerts.
Agent Prompt 
## Issue description
New liveness detections are routed into the existing repository-issue reporting path, which is not an approved automation feedback channel.

## Issue Context
`standards/automation/bot-channels.md` allows machine feedback only as a failed check run or an ordinary PR comment. Route PR-specific liveness findings to ordinary PR comments, or expose the detector result solely through an appropriate failing check run instead of creating or commenting on repository issues.

分页读取所有开放 PR 和 check runs。

pulls?state=open&per_page=30 只读取第一页。第 31 个及之后的开放 PR 不会进入 liveness 检测。check-runs?per_page=100 在 required-check 和 PR liveness 检测中均只读取第一页，后续 check run 可能漏检。

为相关 API 请求增加分页循环，并在分页失败时保持 fail-closed 行为。

5. Queued checks evade aging 🐞 Bug ≡ Correctness

§13 skips pending runs whose started_at is null, even though it explicitly includes queued runs
and the GitHub response schema permits a null start time. Such a run can remain queued indefinitely
without triggering liveness condition (b).
Agent Prompt 
## Issue description
Queued check runs with no `started_at` timestamp are skipped and can never be classified as stale.

## Issue Context
GitHub's check-run schema permits `started_at` to be null. Use a suitable fallback such as the run's creation timestamp for queued runs, while retaining `started_at` for in-progress runs.
