Pull request overview
This PR adds the final “holdout unseal” workflow wiring so the verdict stage can run the holdout gate end-to-end, while also providing a credential-free fixture demo path on PRs plus a static output-surface regression test.
Changes:
- Introduces
.github/workflows/holdout-unseal.ymlwithselftest(PR/dispatch fixture demo) andlive(workflow_call/dispatch live) jobs, including static + runtime leakage audits and ledger/issue writeback in live mode. - Adds a self-referential unit test (
test_workflow_static.py) that enforces the workflow’s output-surface audit invariants (AC-2 anchor). - Adds a small pytest fixture “mini exam set” used by the workflow’s demo path (4 pass, 1 deterministic fail to exercise details + escalation).

1. Missing update file sha 🐞 Bug ≡ Correctness
live job 写回台账时对 GitHub Contents API 的 PUT 请求缺少更新现有文件必须的 sha 字段，导致更新 ledger/unseal.jsonl 时失败（通常 409/422）。结果是台账回传步骤会在真实运行中直接报错，workflow 无法完成揭封闭环。
Agent Prompt
### Issue description
The workflow constructs `commit.json` for `PUT /repos/{owner}/{repo}/contents/{path}` but never includes the existing file's `sha`, even though it is fetched into `base`. GitHub requires `sha` when updating an existing file; omitting it causes the write-back to fail.
### Issue Context
- The step already queries the existing blob SHA into `base`, implying the file is expected to exist.
- The generated JSON payload ignores `base`, so updates will fail.
### Fix Focus Areas
- .github/workflows/holdout-unseal.yml[198-201]
### Implementation notes
- When `base` is non-empty, include it as `sha` in the JSON payload.
- Example: `jq -n --arg c "$content" --arg sha "$base" ... '{message:$m, content:$c, branch:"main", sha:$sha}' ...`
- If `base` is empty (file missing), omit `sha` to create the file (or explicitly handle creation vs update).

2. Fail-closed code overridden 🐞 Bug ☼ Reliability
当 unseal_gate.py 在 strict 模式下因缺少 GH_TOKEN 按设计返回 exit 2（fail-closed）时，后续“写回 issue/台账”步骤会 exit 1 提前终止，从而覆盖原本应透传给 verdict 的 exit 2/3。结果是上游只能看到通用失败码 1，无法按约定区分“无凭据/环境 fail-closed”与“needs-human 升级”。
Agent Prompt
### Issue description
The `live` job intentionally defers the gate exit code to the final "裁决" step via `steps.unseal.outputs.gate_rc`. However, when credentials are missing, intermediate steps hard-fail with `exit 1`, preventing the final step from running and masking the intended `exit 2` (fail-closed) or `exit 3`.
### Issue Context
- `unseal_gate.py` explicitly returns exit 2 when strict mode needs details but `GH_TOKEN` is missing.
- The workflow then exits 1 in the issue/ledger steps if `GH_TOKEN` is missing.
### Fix Focus Areas
- .github/workflows/holdout-unseal.yml[172-213]
- pipeline/holdout-unseal/unseal_gate.py[215-219]
### Implementation notes
- Make the write-back steps conditional on token presence (and/or gate_rc == 0/1), e.g.:
- `if: ${{ secrets.holdout-unseal-token != '' }}`
- Alternatively, in the missing-token branches, exit with `${{ steps.unseal.outputs.gate_rc }}` (default 2) rather than `1`, so the workflow preserves the contract.
- Ensure the final "裁决" step always runs (e.g. `if: always()`) and is the only step that determines the job exit code.

3. Token with mutable ref 🐞 Bug ⛨ Security
live job 允许通过 inputs.holdout-ref checkout 任意 holdout ref，随后在持有 GH_TOKEN 的同一 job 中执行 holdout/scripts/unseal-log.py；若 ref 被误配/被篡改为恶意分支，脚本可直接外传 token。该设计把凭据安全性绑定到外部仓 ref 的可信度，属于供应链风险。
Agent Prompt
### Issue description
The workflow checks out the external `Cloudbird-Software/holdout` repository at a caller-controlled `inputs.holdout-ref`, and later runs `python3 holdout/scripts/unseal-log.py ...` while `GH_TOKEN` is set. If `holdout-ref` points to a malicious ref, the script can exfiltrate the token.
### Issue Context
- This is a classic "execute code from mutable ref" risk.
- The job explicitly sets `GH_TOKEN` for write-back operations.
### Fix Focus Areas
- .github/workflows/holdout-unseal.yml[150-153]
- .github/workflows/holdout-unseal.yml[190-196]
### Implementation notes
Choose one:
1) Pin to a trusted ref (e.g. `main` or a tag) and remove/refuse arbitrary refs in live mode.
2) Require `holdout-ref` to be a full commit SHA and validate it (regex + length) before checkout.
3) Split into two jobs: one without secrets to checkout/validate, and a second gated job with secrets that only operates on verified artifacts (no executing checked-out external scripts under token).

selftest 的 holdout checkout 硬编码 ref: main，忽略 holdout-ref 输入。
第 22 行为 workflow_dispatch 定义了 holdout-ref 输入。第 65 行写死 ref: main。在 workflow_dispatch 且 mode=fixture-demo 时，操作员传入的 holdout-ref 被静默丢弃，fixture 演示始终跑 main。
第 151 行的 live job 正确使用了 ${{ inputs.holdout-ref }}。

泄漏审计失败会跳过台账落账，审计链出现空洞。
第 172 行的注释说明了设计意图：exit 1 必须在台账与明细落定之后。
但本步骤（第 173 行）没有 if: always()。如果泄漏审计发现命中并返回 1，本步骤红，后续的"失败明细写回"（第 178 行）和"台账 append + 回传"（第 189 行）在默认的 success() 条件下被跳过。
结果：gate 已经完成揭封、rec.json 已生成，但本次揭封在 append-only 台账中没有任何记录。这与 AC-3 的审计完整性目标冲突，且泄漏事件本身最需要留下台账痕迹。
建议把泄漏审计的结论也延后到裁决步骤，与 gate_rc 一起判定。

覆盖式 PUT 加上分支不一致，会丢失台账记录。
两个独立缺陷叠加在同一个步骤：
分支不一致。 第 195 行向本地 checkout 的 holdout/ledger/unseal.jsonl 追加。该 checkout 使用 ref: ${{ inputs.holdout-ref }}（第 151 行）。第 198 行和第 201 行读写的是 ref=main。如果调用方传入的 holdout-ref 不是 main，本次追加基于非 main 分支的台账内容，然后整文件覆盖 main。main 上独有的历史记录被抹掉。
无并发保护。 第 36-38 行的 concurrency group 是 holdout-unseal-${{ github.ref }}。不同 PR 的 github.ref 不同，所以不同 PR 的 live 揭封不互斥。第 198 行读 sha、第 201 行整文件 PUT，构成 TOCTOU：两次并发揭封中，后完成的一次会用自己的本地台账覆盖前一次的追加。append-only 保证失效。当前该问题被 sha 缺失导致的 422 掩盖，修好 sha 后就会暴露。
建议：
- 台账回传固定读写同一分支，或直接拒绝
holdout-ref != main的 live 运行。 - 给 live 的台账写入加一个全局互斥的 concurrency group（例如
holdout-ledger-write，不含github.ref），或在 PUT 返回 409/422 时重新拉取 sha 并重放追加。

🌐 Web query:
GitHub REST API Contents PUT update existing file sha required 422
💡 Result:
When using the GitHub REST API PUT /repos/{owner}/{repo}/contents/{path} endpoint to update an existing file, the 'sha' parameter is required [1][2]. If you omit this parameter, the API will return a 422 Unprocessable Entity error with the message "Invalid request. 'sha' wasn't supplied." [3][4][5]. This 'sha' refers to the blob SHA of the file version you are currently replacing [1][2]. Its inclusion serves as a form of optimistic locking to ensure that you are aware of the file's state and to prevent accidental overwrites if the file has been changed by someone else in the meantime [1][2][5]. To resolve this 422 error, follow these steps: 1. Fetch the file metadata first using the GET /repos/{owner}/{repo}/contents/{path} endpoint [6]. 2. Extract the 'sha' value from the response body [6]. 3. Include this 'sha' in the body of your subsequent PUT request [1][2]. Note that if you are creating a new file (one that does not already exist), the 'sha' parameter should be omitted [3]. Including it when creating a new file is not appropriate, as it is only required for updates [1]. If you encounter a 409 Conflict error, it indicates that the SHA provided does not match the current SHA of the file in the repository [3].

将 sha 写入 Contents API 请求体，并区分读取错误
当 ledger/unseal.jsonl 已存在时，Contents API 的 PUT 请求必须包含当前文件的 sha。当前 $b 未写入请求体，因此后续更新返回 422，台账回传失败。仅在确认文件不存在时省略 sha。
不要使用 2>/dev/null || true 混淆 404 与凭据、网络等错误。其他读取错误必须终止步骤并报告。

镜像记录校验在发现字段错误后仍继续执行依赖比较，导致合法记录误拒收或异常退出。
escalated是可选字段，但缺失时前后使用了不同默认值：类型检查使用False，一致性检查使用None，因此合法的verdict="pass"最小记录会被误报为不一致。请统一使用rec.get("escalated", False)，并先在 holdout 仓源脚本修复后同步镜像。passed/total类型非法时只记录错误仍继续比较，字符串等输入会触发TypeError，使append/verify返回错误码或中止方式偏离 fail-closed 契约。请在数值校验失败时跳过大小比较并继续收集校验错误。
这两处都会使台账校验结果偏离声明的退出码和记录契约。

测试方法
本地：17/17 单测绿；demo 全链本地实跑通过（seal→validate→gate×2→ledger→scan，
退出码 0/1，台账两行验链绿，日志零泄漏）。CI：本 PR 的 selftest job 即 e2e。
风险与回滚
非 required check（不挡其他 PR）；live job 在无凭据时 fail-closed（exit 2 注明）
——owner 配置 verdict environment 的 HOLDOUT_UNSEAL_TOKEN（建议细粒度 PAT：仅
holdout 仓 contents:write+issues:write）后生效。回滚=revert（gate 摘除后 holdout
试卷封存无损，ADR-0068 回滚条款）。
