Pull request overview
This PR adds a new GitHub Actions workflow (seed-drill) to automate the weekly “seed defect drill” end-to-end (random sampling → injection → independent gate verification → ledger append → canary drill+sweep linkage) and to run a quarterly fail-close drill that exercises the AUTO_MERGE_DISABLED breaker per ADR-0069 and Card #223.
Changes:
- Introduces
.github/workflows/seed-drill.ymlwith weekly schedule + manual dispatch inputs for reproducible sampling and controlled execution. - Implements the drill execution chain: inject a known defect to a randomly selected target repo, verify expected gate failure, open a P0 issue on “GREEN”, and append an immutable ledger record on the
drill-ledgerbranch. - Adds quarterly fail-close drill job that (in real mode) sets and immediately resets
AUTO_MERGE_DISABLED, then records the result into the same ledger.

- This step uses
set -uo pipefail(no-e), so if v2.json is empty/invalid or the JSON parse fails, it can silently produce an empty verdict and skew the final decision. Use-eso parse/IO failures stop the workflow run.

2. auto_merge_disabled gate missing 📘 Rule violation ≡ Correctness
The workflow dispatches other workflows via gh workflow run without first checking the org variable AUTO_MERGE_DISABLED and aborting when it is set. This can bypass the global automation kill-switch required for unattended dispatch paths.
Agent Prompt
## Issue description
This workflow runs `gh workflow run ...` without a preceding enforced check of the org Actions variable `AUTO_MERGE_DISABLED`.
## Issue Context
Policy requires a kill-switch check (`gh api /orgs/Cloudbird-Software/actions/variables/AUTO_MERGE_DISABLED --jq .value`, treating 404 as "not set") before any task dispatch or auto-merge action.

3. Canary dispatch lacks cost checks 📘 Rule violation ☼ Reliability
The workflow dispatches follow-up workflows without gating on open cost-blocker issues (cost-infra/cost-circuit-breaker) or halting when cost/usage is unavailable/unknown. This can trigger automation during a cost incident or while usage visibility is degraded.
Agent Prompt
## Issue description
Before calling `gh workflow run ...`, the workflow does not check for open cost-related blockers in `Cloudbird-Software/.github` nor verify that usage information is available.
## Issue Context
Policy requires dispatch to halt when `.github` has open `cost-infra` or `cost-circuit-breaker` issues, or when usage is unknown/unavailable.

4. Verifier 吞错变 skipped 🐞 Bug ☼ Reliability
verify1/verify2 用 || true 且未启用 set -e，当 verify_gate.py 因凭据/API/JSON 异常未输出有效 JSON 时，后续解析失败不会终止步骤，最终 VERDICT 可能为空并在入台账时被降级为 skipped。这样既不会走 GREEN 的 P0 开立路径，也会让演习结果被健康度统计忽略，等同于验证链路 fail-open。
Agent Prompt
### Issue description
`verify_gate.py` 在异常情况下可能不输出 JSON（或输出非 JSON），但 workflow 通过 `|| true` 忽略退出码、且 step 未开启 `set -e`，导致 JSON 解析失败后仍继续执行，最终把“验证基础设施故障”当成正常结果（甚至入台账为 skipped），从而错过应有的 P0/告警。
### Issue Context
- `verify_gate.py` 在缺少 GH_TOKEN 时会直接退出并只写 stderr。
- 网络/API/JSON 解析异常在脚本内未捕获，同样会在打印 JSON 前退出。
- workflow 当前用 `|| true` 抑制这些错误，并在无 `-e` 时继续执行后续 JSON 解析与 finalize。

- .github/workflows/seed-drill.yml[166-172]
- .github/workflows/seed-drill.yml[227-231]
### Suggested fix
1. 在 verify1/verify2 step 内使用 `set -euo pipefail`，并显式区分“预期非 0（GREEN/中间态）”与“异常非 0（infra）”。示例思路：
- `python3 ... > v1.json; rc=$?`（不要 `|| true`）
- 允许 rc ∈ {0,1,3}；否则 `exit $rc`。
- 在读取 verdict 前，先校验 `v1.json` 非空且可被 `json.load` 解析；校验 `verdict` 属于允许集合（RED/GREEN/NO-SURFACE/MISSING-GATE/TIMEOUT）。
2. finalize 中对空 verdict/未知 verdict 直接 `::error::` 并失败退出（或至少记录为 `infra` 并触发告警），避免被当作“既非 GREEN 也非 RED”的静默状态。
3. 台账记录时不要把空字符串 VERDICT 变成 skipped；应只在 skip_inject=true 的显式干跑路径记录 skipped（或记录 `infra` 并让 redrate/告警可见）。

5. 台账可写入无效记录 🐞 Bug ≡ Correctness
workflow 可能把空/未知 verdict 写入 history.jsonl，而 drill.py 的 record 仅校验 ts/kind，不会拒绝缺字段/异常 verdict；同时 redrate 的分母只统计 red+green，导致无效记录（skipped/空/未知）被健康度计算忽略。这样会掩盖演习链路不完整或数据被污染的问题。
Agent Prompt
### Issue description
`record` 子命令对记录 schema 约束过弱（只要求 ts/kind），而 redrate 又只用 red/green 计入分母。当前 workflow 在 VERDICT 为空/异常时仍可能写入 seed-drill 记录，造成 dashboard 指标被“静默稀释”。
### Issue Context
该 workflow 是 history.jsonl 的主要写入者之一，一旦写入无效行，会长期影响聚合指标与审计可读性。

- .github/workflows/seed-drill.yml[227-246]
- governance/drill/drill.py[210-217]
- governance/drill/drill.py[233-245]
### Suggested fix
1. 在 workflow 侧：构造 `rec.json` 前对必需字段做断言（sample_id/target_repo/gate/difficulty/verdict 等），并将“验证基础设施失败”记录为明确的 `infra`/`error` verdict（不要用 skipped）。
2. 在 `drill.py cmd_record` 侧：当 `kind==seed-drill` 时强制校验：
- `verdict` ∈ {red, green, no-surface, missing-gate, timeout, skipped, infra}（按你们口径定集合）；
- `sample_id/target_repo/gate/difficulty` 等关键字段存在且类型正确。
3. 在 `cmd_redrate` 侧：考虑把 `infra/timeout/missing-gate` 等纳入“不可判定但必须可见”的指标，并在输出里显式报告其数量（避免被分母排除后“看起来很健康”）。

6. Failclose 通过判定过宽 🐞 Bug ☼ Reliability
failclose step 仅用 grep -qE 'real-pass|dry-run-pass' fc.log 判定通过，没有校验该 token 是否来自脚本最终 AUDIT 行、是否与期望 mode 匹配，也没有 fail-fast 依赖脚本退出码。日志内容被污染/截断时可能出现误判通过。
Agent Prompt
### Issue description
failclose 结果判断仅做了宽松 grep，可能在日志出现相同子串时误判通过，且未确保结果与真实执行模式一致。
### Issue Context
`failclose-test.sh` 已有清晰的退出码语义与 mode 区分（dry-run vs real），workflow 可以更严格地使用它们。
### Fix Focus Areas

- governance/drill/failclose-test.sh[108-113]
- governance/drill/failclose-test.sh[133-140]
### Suggested fix
1. 在 workflow step 中改为 `set -euo pipefail`，让脚本非 0 直接失败。
2. 如仍需二次校验日志：
- 只匹配以 `AUDIT | butler=failclose-drill | ... | outcome=real-pass` 或 `outcome=dry-run-pass` 结尾的行（建议用 `grep -E '^AUDIT \| .*\| outcome=(real-pass|dry-run-pass) \|'`）。
- 同时验证该 outcome 与 `MODE` 一致（MODE=0 必须 real-pass）。

7. Token 嵌入 git url 🐞 Bug ⛨ Security
台账 clone/push 使用 https://x-access-token:${DRILL_TOKEN}@github.com/... 形式把高权限 token 放入 URL，git
出错信息/remote 展示等场景可能将其带入日志或工具输出（即使 GitHub 有 masking，也存在截断/编码导致的漏遮风险）。同仓的 inject 逻辑已经采用 extraheader
方式避免 token 出现在 URL，台账路径建议对齐。
Agent Prompt
### Issue description
在 workflow 日志/错误输出中暴露 PAT 的风险：当前通过 URL 内嵌 token 的方式执行 `git clone/push`。
### Issue Context
`governance/drill/drill.py` 的 inject 已通过 `http.https://github.com/.extraheader` 注入 Authorization header 来避免 token 出现在 URL/remote 中。

- .github/workflows/seed-drill.yml[254-255]
- .github/workflows/seed-drill.yml[292-295]
- governance/drill/drill.py[160-168]
### Suggested fix
1. clone：使用不带 token 的 URL（https://github.com/Cloudbird-Software/.github.git），并通过 `git -c http.https://github.com/.extraheader='Authorization: Basic ...' clone ...` 方式传入凭据。
2. push/pull：同样用 `-c http.https://github.com/.extraheader=...`（或设置临时 repo config）后再执行 push/pull。
3. 确保相关命令不回显 header 内容（不要 `set -x`）。

8. Canary run 可能串台 🐞 Bug ☼ Reliability
canary 联动用 gh run list ... -L 1 取“最新一条” run 并 watch；若期间有人/定时任务触发同 workflow，新 run 会覆盖最新位置，导致本次演习 watch 到错误的 run，从而误判 healthy/unhealthy。
Agent Prompt
### Issue description
通过“取最新一条 run”来定位刚 dispatch 的工作流存在竞态：同一 workflow 同时/相近时间触发会导致选中错误 run。
### Issue Context
该步骤用于验证检测通道健康度，误判会直接影响演习结论可信度。
### Fix Focus Areas
- .github/workflows/seed-drill.yml[194-202]
### Suggested fix
1. 在 dispatch 前记录当前时间 `T0=$(date -u +%FT%TZ)`。
2. `gh run list` 时拉取 `databaseId, createdAt, event`，筛选 `event=="workflow_dispatch"` 且 `createdAt >= T0` 的最早/最新一条（取决于实现），必要时循环重试等待该 run 出现。
3. 或者给被触发 workflow 增加可传入的唯一 correlation id（如 run_id）并在 run name/输出中回显，然后按该标识筛选。

不要在验证或台账持久化失败后继续报告成功。
verify_gate.py 可能以非零状态返回；当前处理会吞掉该状态，解析失败后仍可能写入空 verdict 并继续 finalize。请捕获退出码，校验输出为有效 JSON，且 verdict 属于 RED、GREEN、NO-SURFACE、MISSING-GATE 或 TIMEOUT，否则在清理后以非零状态退出。
两个台账推送重试循环在三次 git push 均失败时最后执行 sleep，因此步骤仍会成功并让 redrate 读取未持久化数据。请记录推送是否成功，全部失败时输出 error 并以非零状态退出；同样适用于普通演习和 failclose 台账推送。

GitHub CLI gh workflow run output run ID gh run list default order created latest documentation
💡 Result:
As of February 2026, the GitHub CLI (gh) supports returning workflow run details when triggering a workflow [1]. GitHub CLI Workflow Run Output Starting with version 2.87.0, the gh workflow run command has been updated to return the URL of the created workflow run upon success, provided the underlying server supports it [1]. This improvement addresses long-standing community requests by utilizing the workflow dispatch API's ability to return run details [1][2][3]. If the API server does not support returning run details (such as older GitHub Enterprise Server versions), the command maintains its historical behavior: providing a success message and exiting with code 0 in interactive mode, or simply exiting with code 0 in non-interactive mode [2][3]. gh run list Default Order The gh run list command does not have a user-configurable parameter to specify sort order [4]. It relies on the underlying GitHub REST API, which typically returns runs in descending order by creation time (created desc) [4]. However, because the exact ordering of items created within the same timeframe may not be strictly guaranteed, the order can occasionally appear volatile [4]. Summary of Key Commands gh workflow run [workflow]: Triggers a manual workflow dispatch [5][6]. It now outputs the created run's URL when supported [1]. gh run list: Fetches recent workflow runs, typically sorted by creation time (latest first) [7][4]. Note that it does not provide an explicit sort flag [7][4].

GitHub Actions jobs needs failed skipped if condition always() default status check documentation
💡 Result:
In GitHub Actions, jobs possess a default status check of success [1]. This means that if you do not specify an if condition for a job, it will only run if all of its dependent jobs (defined in the needs keyword) have completed successfully [2][3]. If a required job fails or is skipped, any subsequent jobs that depend on it are automatically skipped by default [2][3][4]. To force a job to execute even when previous dependencies have failed or were skipped, you must override this default behavior using status check functions within an if conditional [2][3]. Key considerations for overriding this behavior: 1. Using always: By adding if: ${{ always }} to your job, you force it to run regardless of the status of the jobs it depends on [2][3]. 2. Handling Cancelled Jobs: Note that always does not prevent a job from running if the workflow was cancelled [1]. If you want a job to run in all cases except when the workflow is explicitly cancelled, the recommended approach is to use if: ${{!cancelled }} [1][5]. 3. Dependency Results: When using always or!cancelled, you may still need to account for the specific outcomes of your upstream jobs to avoid unexpected logic execution [4]. You can inspect the status of needed jobs using the needs context (e.g., needs.<job_id>.result) [1][4]. For example, if you want a job to run even if a previous job was skipped, you might use: if: ${{ always && (needs.job_id.result == 'success' || needs.job_id.result == 'skipped') }} [5][6] If you do not include a status check function (like always, success, failure, or cancelled) in your if conditional, the default status check of success remains applied, which can lead to your job being skipped if your custom condition evaluates to true but the dependencies were not successful [1][7].

即使 drill 失败，也执行季度 failclose
failclose 使用 needs: drill，但 if 未包含状态检查函数。drill 失败或被跳过时，GitHub Actions 会跳过 failclose，导致季度 fail-closed 回归不执行。保留 needs: drill 的顺序约束，并使用 always() 包裹现有条件。
