ensuring the final ok condition remains unreachable when a query fails.
- Around line 498-510: Update the open-PR retrieval in the liveness flow and the
check-runs retrieval around CRS so they iterate through all API pages rather
than inspecting only the first page. Accumulate or process every page for open
PRs and check runs, and preserve fail-closed behavior by invoking drift and

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。

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.

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.

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.

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.

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.

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.

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.

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`.

摘要
自动合并计划 P1-4（#85，ADR-0034 已合入 agent-registry#50）。给 drift-check 补两个"文本对账看不见"的检测：
rulesets/*.json的 required_status_checks 派生，单一真源；当前 =gate）的 check run 且 conclusion 非空。fail-closed：查询失败即判漂移。变更
drift-check.sh：§12 + §13（fail-closed 语义与 §1-§11 一致）expected-state.json：pr_liveness_hours: 4governance-drift.yml：dispatch inputliveness_hours透传（负向注入测试入口，缺省走期望状态真源）验证
C1 声明：governance/ + .github/ 路径，ADR-0034 背书。
