1. gov_token bypasses approved scripts 📘 Rule violation ⛨ Security
The workflow uses secrets.GOVERNANCE_TOKEN directly for GitHub API calls, instead of obtaining tokens via scripts/ghcb or scripts/gh-app-token.sh with single-repo scope. This can introduce over-privileged/org-scoped credentials into automation flows.
Agent Prompt
## Issue description
`.github/workflows/conductor.yml` uses `secrets.GOVERNANCE_TOKEN` (`GOV_TOKEN`) directly to call the GitHub API, which violates the requirement that agent operations obtain tokens only via approved scripts (`scripts/ghcb` or `scripts/gh-app-token.sh`) with single-repo scope.
## Issue Context
This workflow already mints an App installation token via `scripts/gh-app-token.sh`. The remaining org-membership lookup must be reworked to avoid using a separate secret token (likely org-scoped).

2. gh api missing app token 📘 Rule violation ⛨ Security
The on-failure notification step mints a GitHub App token but does not export it as GH_TOKEN/GITHUB_TOKEN for the gh api call, so it may fall back to the restricted default runner token (or fail) instead of using an approved-script token as required. Additionally, the failure comment can break because ISSUE is sourced from needs.route.outputs.issue, which is not set on many failure paths, potentially producing an invalid .../issues//comments endpoint.
Agent Prompt
## Issue description
In `.github/workflows/conductor.yml`, the `on-failure` job is intended to comment on the original issue (BEH-01), but it mints an App token via `scripts/gh-app-token.sh` and then calls `gh api` without explicitly authenticating `gh` with that token (e.g., by exporting `GH_TOKEN`/`GITHUB_TOKEN`), which can cause the call to use the restricted default `GITHUB_TOKEN` (permissions only include `contents: read`) or fail. The comment endpoint can also be invalid because `ISSUE` is taken from `needs.route.outputs.issue`, which is not written on many failure paths.
## Issue Context
- Compliance policy (PR Compliance ID 2778539) requires agent GitHub operations to obtain and use GitHub tokens via approved scripts such as `scripts/ghcb` or `scripts/gh-app-token.sh` (single-repo scope).
- The workflow claims BEH-01 (“启动失败在原 issue 评论原因”), so the failure-comment path must be reliable even when earlier steps in `route` fail.

3. Missing pyyaml dependency 🐞 Bug ☼ Reliability
The router step imports yaml and calls yaml.safe_load, but this workflow never installs PyYAML (no pip install/setup-python), so it can fail at runtime with `ModuleNotFoundError: No module named 'yaml'` depending on the runner image. This would break all routing and downstream state transitions.
Agent Prompt
### Issue description
The embedded Python script uses `import ... yaml` and `yaml.safe_load(...)`, but the workflow doesn't install PyYAML. GitHub runner images do not guarantee PyYAML is available, so the workflow can fail immediately.
### Issue Context
The repo already pins PyYAML in `.github/requirements-gate.txt`, but `conductor.yml` doesn't consume it.
### Fix Focus Areas
- .github/workflows/conductor.yml[29-60]
- .github/workflows/conductor.yml[119-122]
- .github/requirements-gate.txt[1-1]
### Suggested changes
Add a small dependency-install step before running the Python router, e.g.:
- Use `actions/setup-python` with an explicit version, then:
- `python3 -m pip install -q --require-hashes -r .github/requirements-gate.txt`
If you want to avoid pip entirely, replace YAML with JSON or implement a minimal YAML parser is not recommended; the simplest fix is to install the pinned dependency.

4. Eval sandbox bypass risk 🐞 Bug ⛨ Security
The workflow executes transition guards using Python eval(...) with user-defined expressions from governance/transitions.yaml, which is not a safe sandbox even with __builtins__ cleared. A malicious or mistakenly-expanded guard can escape and execute arbitrary code on the runner, potentially exposing secrets (App token, governance token).
Agent Prompt
### Issue description
`eval(t["guard"], {"__builtins__": {}}, ...)` is not a safe sandbox; Python object graph traversal can recover dangerous capabilities even when builtins are removed.
### Issue Context
Even though `transitions.yaml` is intended to be a controlled governance asset, this pattern is a long-term footgun: future edits can accidentally introduce code execution, and any compromise of that file becomes immediate runner RCE.
### Fix Focus Areas
- .github/workflows/conductor.yml[127-134]
- governance/transitions.yaml[17-41]
### Suggested changes
Implement a tiny safe expression evaluator:
- Parse with `ast.parse(expr, mode="eval")`
- Walk the AST and allow only a strict whitelist of nodes, e.g.:
- `Expression`, `BoolOp`, `And/Or`, `UnaryOp(Not)`, `Compare`, `In/NotIn`, `Eq/NotEq`, `Name`, `Constant`, and (optionally) `List/Set` literals.
- Explicitly reject `Attribute`, `Call`, `Subscript`, comprehensions, lambdas, f-strings, etc.
- Evaluate by recursively computing the AST against the provided env vars.
This preserves the current guard DSL while removing arbitrary code execution risk.

5. State label swap inconsistent 🐞 Bug ☼ Reliability
swap_state() ignores HTTP results for both deleting the old state label and adding the new one, so partial failures can leave an issue with multiple state:* labels or none; the next run hard-aborts when multiple state labels exist. This can wedge issues into an unrecoverable state without manual cleanup.
Agent Prompt
### Issue description
`swap_state()` performs two API calls (DELETE old state label, POST new state label) but does not check status codes. If one call succeeds and the other fails (transient network error, permissions regression, label already removed, etc.), the issue can end up with:
- two `state:*` labels (DELETE failed, POST succeeded), or
- no `state:*` label (DELETE succeeded, POST failed).
Since the router later aborts on `len(states) > 1`, this can permanently break the state machine for that issue until a human fixes labels.
### Issue Context
The abort behavior is already implemented as fail-closed when multiple state labels exist; that increases the importance of making label swaps atomic/validated.
### Fix Focus Areas
- .github/workflows/conductor.yml[109-118]
- .github/workflows/conductor.yml[135-140]
### Suggested changes
- Capture and validate the HTTP status for both calls:
- For DELETE: treat 200/204 as success; treat 404 as acceptable if label already missing; otherwise fail.
- For POST: require 200/201.
- On failure after DELETE, consider restoring the original state label (best-effort) or at least fail loudly so the on-failure notifier triggers.
- After swap, optionally re-fetch labels and assert exactly one `state:*` label exists (defensive consistency check).

🌐 Web query:
Is PyYAML preinstalled on the GitHub Actions ubuntu-24.04 runner image system python3 in 2026?
💡 Result:
No, PyYAML is not preinstalled on the GitHub Actions ubuntu-24.04 runner image's system Python [1][2]. GitHub maintains an official list of installed software for its runner images, and PyYAML is not included in the preinstalled packages for the Ubuntu 24.04 runner [1][2]. Users requiring PyYAML must install it during their workflow execution, typically by using pip, such as running pip install PyYAML [3][4]. GitHub documentation recommends using the actions/setup-python action to manage Python environments and dependencies, which helps avoid issues related to system-level package management [4][5].

api() 缺少超时，且错误正文被丢弃。
urllib.request.urlopen 不设 timeout 时使用全局默认值，通常为无限等待。单次挂起会占满 5 分钟 job 预算，并阻塞同一 issue 的串行队列（INV-09）。
HTTPError 分支返回空字典，丢掉了 GitHub 的错误消息。第 112 行的审计日志只剩状态码，排障信息不足。第 104-106 行的 org membership 判定也受影响：403 或 5xx 与「非成员」无法区分，owner 会被当作 none 静默拒绝。
🛡️ 建议修复：加超时并保留错误正文

换签失败被静默忽略，状态标签与下游执行会不一致。
api() 在 HTTP 错误时返回状态码与空字典（第 73-74 行），而 swap_state 丢弃了两次调用的返回值。DELETE 或 POST 失败时函数仍然正常返回，第 157 行随即写出 invoke=spec-author，spec job 照常启动。
结果：issue 停留在 from_state，但 spec 阶段已经执行。下一次同一事件再投递又会命中同一转移，幂等性（INV-09 依赖 from_state 匹配）失效。
另外第 136 行的 enc_from 计算后未使用，第 137 行硬编码 state%3A{frm}，两处编码方式不一致。
🐛 建议修复：校验换签状态码并统一编码

- enc_from = urllib.parse.quote(f"state:{frm}", safe="")
- api(E["APP_TOKEN"], f"/repos/{REPO}/issues/{ISSUE}/labels/state%3A{frm}", "DELETE")

route 失败时 ISSUE 为空，评论 API 路径非法。
route job 的所有失败出口都在写 GITHUB_OUTPUT 之前：第 112 行读取 issue 失败、第 117 行多状态标签、第 133 行 guard 求值失败。这三条路径都不会产出 issue 输出。
此时 ISSUE 为空字符串，请求路径退化为 repos/.../issues//comments，通知再次失败。请直接使用事件里的 issue 号。

严重（Critical）：gh api 缺少 GH_TOKEN，失败通知一定不会发出。
第 210 行把令牌赋给 TOKEN，但第 212 行的 gh api 没有拿到它。GitHub CLI 预装在所有 GitHub 托管 runner 上，但每个使用 GitHub CLI 的 step 都必须设置 GH_TOKEN 环境变量。actionlint 的 SC2034（TOKEN 未使用）指向同一根因。
当前 job 的 permissions 只有 contents: read，即使回退到 GITHUB_TOKEN 也无 issues 写权。BEH-01 的「失败在原 issue 评论」承诺无法实现。
