Pull request overview
This PR adjusts the weekly SLI calculation to exclude drill (“演练” / “[drill]”) data from the escape_rate numerator, to avoid inflating risk metrics and triggering unnecessary P1 escalations. It also makes the exclusion visible via a drills_excluded counter and adds a self-test assertion to lock in the behavior.
Changes:
- Filter drill-marked PRs out of the
[auto-revert](escape numerator) count and exposedrills_excludedin output. - Fetch PR bodies into the local merged PR dataset to enable title/body-based drill detection.
- Update post-merge P0 issue counting logic to apply the same drill exclusion and extend self-test coverage for the drill filter.

2. sli-report.sh 直用 gh_token 📘 Rule violation ⛨ Security
脚本通过环境变量 GH_TOKEN 直接驱动 gh api，未按要求通过 scripts/ghcb 或 scripts/gh-app-token.sh 获取单仓库 scope 的 token。该做法可能导致使用过宽权限的凭证或不可审计的 token 来源。
Agent Prompt
## Issue description
`scripts/sli-report.sh` performs authenticated GitHub API operations via `gh`, but it requires `GH_TOKEN` to be set externally instead of obtaining a repo-scoped token via approved scripts (`scripts/ghcb` or legacy `scripts/gh-app-token.sh`).
## Issue Context
This PR modifies/adds `gh api` usage (including org-wide search), so the script continues to rely on an unapproved token acquisition path.
## Fix Focus Areas

3. P0 drill过滤jq转义错误 🐞 Bug ≡ Correctness
P0 查询的 jq 里写了 test("演练|\[drill\]")，在 jq 字符串字面量中 \[ / \] 属于非法转义，导致 jq 解析失败并触发“|| echo 0”静默回退，从而把 P0
计数错误地变成 0。结果 escape_rate 的 P0 分子会被系统性漏计，可能直接掩盖连续两周>0 的升级条件。
Agent Prompt
### Issue description
`scripts/sli-report.sh` 的 P0 计数使用 jq `test("演练|\[drill\]")`，其中 `\[` / `\]` 在 jq 字符串字面量里是非法转义，容易导致 jq 直接 parse error；随后 `|| echo 0` 会把 P0 静默当成 0。
### Issue Context
需要从 P0 分子中排除“演练/[drill]”标记，但过滤逻辑必须稳定且可观测，不能在解析失败时 fail-open（把风险指标压成 0）。
### Fix Focus Areas
- scripts/sli-report.sh[169-171]
### Suggested fix
- 避免 jq `test()` 字符串转义陷阱，改用 `contains()`：
- `select(((.title + (.body // "")) | contains("演练") or contains("[drill]")) | not)`
- 或者若坚持 regex：`test("演练|\\[drill\\]")`
- 去掉静默 `|| echo 0` 的 fail-open；至少在失败时 `infra "P0 搜索失败"` 并让脚本以基础设施故障退出（或显式标记 `P0=N/A` 并阻断升级判定）。

5. Drills_excluded含义不完整 🐞 Bug ◔ Observability
drills_excluded 目前只统计了 auto-revert 分子中被排除的数量，但 P0 分子同样做了演练过滤却没有对应的 excluded 计数，导致输出里的 drills_excluded 容易被误解为“分子总排除数”。这会降低指标的可解释性，尤其在需要审计/回溯过滤影响时。
Agent Prompt
### Issue description
`drills_excluded` 当前仅计算 auto-revert 列表中被 is_drill 排除的数量，但 P0 侧也在做 drill 过滤（或将会做），输出却没有体现 P0 的排除数，容易被误读。
### Issue Context
输出目前是：`escape_rate=... (reverts=...+p0=... / merged=..., drills_excluded=...)`，从文案上看像是“分子过滤总览”。
### Fix Focus Areas
- scripts/sli-report.sh[143-148]
- scripts/sli-report.sh[157-160]
- scripts/sli-report.sh[169-171]
### Suggested fix
- 方案 A：将变量重命名为 `revert_drills_excluded`，避免误解。
- 方案 B：为 P0 也增加 `p0_drills_excluded`，并在同一行输出两者或输出 `drills_excluded_total=revert_excluded+p0_excluded`。
- 无论哪种方案，确保 excluded 的统计口径与实际过滤逻辑一致。

分别检查标题和正文，并补充对应自测。
请避免把 title 和 body 拼接后匹配演练标记，否则一个字段结尾与另一个字段开头可能跨字段形成误匹配并排除合法记录。实现和自测都应分别覆盖标题或正文中的“演练”及 [drill]，并验证普通记录、演练记录和 P0 结果的保留与排除计数。

让 drills_excluded 覆盖 P0 排除项。
当前计数只包含被排除的 [auto-revert] PR。Line 170 还会过滤演练标记的 P0 issue，但这些 issue 不会计入 drills_excluded。因此报告值小于实际从 escape_rate 分子删除的记录数。请让 P0 查询同时返回保留数和排除数，并将排除数累加到 drills_excluded；或者明确报告单独的 P0 排除计数。

修正 jq 正则转义，并让查询失败可见。
当前表达式会导致 jq 编译失败。|| echo 0 会将失败静默转换为 P0=0，使 escape_rate 偏低。请使用 test("演练|\\[drill\\]")，并在查询失败时调用 die。

🌐 Web query:
GitHub CLI gh api manual --paginate --slurp REST JSON response pagination
💡 Result:
In the GitHub CLI, the --paginate and --slurp flags work together to handle API responses across multiple pages [1][2]. When you use --paginate, the GitHub CLI automatically makes additional HTTP requests to fetch all available pages of results until no more pages remain [1][3]. By default, each page is returned as a separate JSON object or array [1][4]. When you add the --slurp flag, the CLI wraps all pages of JSON responses into a single, outer JSON array [1][5]. This essentially transforms a stream of individual page responses into a single, combined array [5]. Key technical constraints and usage notes include: 1. Mutual Exclusion: You cannot use --slurp in combination with --jq or --template [5]. The CLI explicitly prevents this because --slurp is designed to return the raw, combined JSON structure of all pages, which would conflict with the filtering or formatting logic of --jq and --template [6][5]. 2. Structure: Because --slurp simply wraps each page's response into a new outer array, the resulting structure is an array of the original page responses (e.g., [Page1, Page2,...]) [6][7]. It does not automatically merge nested arrays (e.g., concatenating items from multiple pages into one flat list) [6]. 3. Requirement: You must use --paginate in order to use --slurp [5]. If you need to process paginated data using jq, the recommended workaround is to use --paginate without --slurp, apply your --jq filter to each individual page response, and then pipe the output to the standalone jq tool using its own --slurp (-s) flag [8]: gh api --paginate --jq '.path.to.array[]' | jq -s.
