- Around line 37-41: Update the workflow step after invoking
scripts/sli-report.sh so infrastructure failures with exit_code 2 still emit the
existing error and fail, while returning the original exit_code for all other
outcomes. Preserve the exit-code contract so threshold escalation with exit_code
1 makes the workflow fail rather than unconditionally exiting successfully.
In `@scripts/sli-report.sh`:
- Around line 104-110: Update the REPOS parsing in the SLI report flow to select
only entries whose status is active, and remove the hardcoded fallback list.
When parsing REPOS.yaml fails or produces no active repositories, invoke the
existing infra failure path with exit code 2 instead of continuing with
fabricated repositories.
- Around line 114-120: The PR collection in the loop must fetch all pages by
adding pagination to both merged and open pull requests, record failures for
both requests instead of ignoring open PR errors, and check INFRA before metric
calculation to exit with status 2 when any collection failed. Update the gh api
calls and the later report-generation flow without changing unrelated behavior.
- Around line 36-99: 处理脚本参数解析中的 --audit-only 接口：要么实现仅重放抽样且不执行完整采集、周报创建或审计 issue
写入的分支，要么移除该接口及文档声明；同时确保传入该参数不会进入当前完整采集路径。定位并更新 --self-test 旁的参数处理逻辑。
- Around line 203-206: Update the ESCALATE branch around gh issue create to
first query open P1 issues in GOV_REPO matching the same SLI escalation, then
skip creation or append the current weekly report link when one exists; only
create a new issue when no matching open issue is found, while preserving the
existing failure exit behavior.
- Around line 136-139: 调整指标生成流程：在计算 esc 及其他依赖 P0 的指标前，先完成 P0 计数查询并验证其结果，确保 p0
读取到真实值；将当前指标文件生成后才写入 p0count 的逻辑移到计算之前。查询失败时应明确失败或中止流程，不得通过 echo 0 或其他默认值伪造 P0
数据。
- Around line 140-143: Replace the process-randomized hash used to initialize
the Random instance in the agent_merged sampling expression with a deterministic
seed derived from the ISO week, such as the ISO week string itself or a stable
hashlib-based integer, so runs in the same week select the same sample.
- Line 42: Remove the unbound SLI_SELFTEST_DIR expansion from the PY_CALC

Line 33 直接注入 GOVERNANCE_TOKEN。此路径无法强制 GitHub App cloudbrid-agent 身份、单仓作用域和 1 小时过期。该 job 会读取多个仓库并在 .github 创建 issue，因此应按目标仓库分别获取令牌，并为 .github 写入操作获取独立令牌。

实现 --audit-only 分支，或删除该接口。
文档在 Line 18 声明 --audit-only 只重放抽样。当前代码只识别 --self-test。传入 --audit-only 会进入完整采集路径并创建周报和审计 issue。该行为会产生非预期的外部写入。

around gh issue create to first query open P1 issues in GOV_REPO matching the
same SLI escalation, then skip creation or append the current weekly report link
when one exists; only create a new issue when no matching open issue is found,
while preserving the existing failure exit behavior.

2. Self-test unbound variable 🐞 Bug ≡ Correctness
workflow 的自测步骤会因脚本在 --self-test 分支引用未定义的 SLI_SELFTEST_DIR 且启用 set -u 而直接退出，导致整个 workflow 永远跑不起来。
Agent Prompt
### Issue description
`--self-test` 分支在 `set -u` 下引用未定义的 `SLI_SELFTEST_DIR`，会触发 `unbound variable` 并使 workflow 自测步骤失败。
### Issue Context
workflow `.github/workflows/sli-weekly.yml` 每次运行都会先执行 `bash scripts/sli-report.sh --self-test`，因此该问题会导致整个工作流不可用。
### Fix Focus Areas
- scripts/sli-report.sh[22-43]
- .github/workflows/sli-weekly.yml[29-31]
### What to change
- 将 `"$SLI_SELFTEST_DIR"` 改为安全展开：`${SLI_SELFTEST_DIR:-}` 或直接移除该未使用参数。
- 如确实需要 fixture 目录，统一变量名（注释写的是 `SLI_FIXTURE_DIR`），并在 self-test 分支内对其设置默认值/显式校验（给出清晰错误）。

3. Non-deterministic sample seed 🐞 Bug ≡ Correctness
抽样审计宣称 seed=ISO 周可复现，但代码使用 Python 的 hash() 作为 seed（且显式走 if False else 分支），hash 默认跨进程随机化，导致同一周样本在不同运行中不一致。
Agent Prompt
### Issue description
抽样 seed 使用了 `hash(f"{year}-W{week}")`，该值在 Python 默认启用 hash randomization 时跨进程不稳定，破坏“可复现、防挑软”的审计设计。
### Issue Context
脚本输出 `SAMPLE_SEED=YYYY-Www` 作为复现依据，但实际 seed 与该字符串并非一一对应的稳定映射。
### Fix Focus Areas
- scripts/sli-report.sh[140-153]
### What to change
- 用稳定的确定性哈希替代 `hash()`，例如：
- `seed_str = f"{year}-W{week:02d}"`
- `seed = int.from_bytes(hashlib.sha256(seed_str.encode()).digest()[:4], 'big')`
- 或直接用 `random.Random(seed_str)`（字符串 seed 在 Python `random` 内部会稳定处理）。
- 移除 `if False else` 的死代码，避免误导/未来回归。

4. P0 excluded from escape_rate 🐞 Bug ≡ Correctness
escape_rate 在生成 metrics 时尝试读取 $TMP/p0count，但该文件在 metrics 计算之后才写入，导致周报/升级判定中的 escape_rate 永远不会包含 post-merge P0 分子。
Agent Prompt
### Issue description
`metrics.txt` 生成时读取 `p0count`，但 `p0count` 是在 metrics 生成后才通过 GitHub Search 写入的，因此 `p0` 基本恒为 0（或旧文件残留），使 `escape_rate` 分子计算错误。
### Issue Context
`escape_rate` 被用于周报与“连续两周>0”的 P1 升级判定；分子缺失会导致风险被系统性低估。
### Fix Focus Areas
- scripts/sli-report.sh[123-159]
### What to change
- 将 P0 search 写入 `$TMP/p0count` 移到生成 `metrics.txt` 之前；或
- 先生成 `metrics.txt`（不含 P0），写入 `p0count` 后重新生成一次 metrics（或在 Python 内部直接调用 search 而不是依赖外部文件）。
- 同时建议：若 P0 查询失败，应计入 INFRA 并 fail-closed（见另一条 finding）。

5. Missing pagination skews metrics 🐞 Bug ☼ Reliability
PR 列表采集对每仓仅请求 per_page=50 且不分页，窗口内合并/打开 PR 超过该数量时会被截断，导致 auto_merge_rate/escape_rate/stuck_prs/pr_duration_p95 等指标错误并可能掩盖阈值升级。
Agent Prompt
### Issue description
采集每个 repo 的 PR 列表使用 `per_page=50` 且未做分页聚合；当窗口内 PR 数量 > 单页时，指标计算基于部分数据，会系统性低估分母/分子，并影响阈值升级的正确性。
### Issue Context
仓库增长后该问题会变成常态；历史上本仓库已多次出现“只取第一页导致假绿”的同类缺陷。
### Fix Focus Areas
- scripts/sli-report.sh[112-121]
### What to change
- 使用 `gh api --paginate` 拉全量页面并聚合，再交给 jq 过滤（或实现显式 page 循环并处理 `Link` 头）。
- 将 `per_page` 提升到 100，并确保排序/筛选不会因为 `sort=updated` 导致窗口内旧 merged PR 被挤出第一页。
- 对 open PR 列表也做同样分页，否则 stuck_prs 会被低估。

.github/workflows/sli-weekly.yml:2
- 这里引用的
ADR-0049在agent-registry中已经存在，但其标题和内容是“conductor 状态机骨架与事件入口安全”，不是本 SLI；同时 #98 已被关闭并吸收到 #168。gate 只校验编号存在，因而会把错误 ADR 当成背书。请为 SLI 使用对应的 ADR 并更新追踪关系后再合入。
# P3-4（.github #98，ADR-0049）：自动合并门禁自身 SLI 周报 + 每周抽样审计。
scripts/sli-report.sh:119
- open PR 查询同样只取第一页，而且用
|| true吞掉 API 错误；这会把stuck_prs静默低报，甚至在数据源不可用时仍生成绿色报告。请分页并传播失败状态。
gh api "repos/$ORG/$R/pulls?state=open&per_page=50" \
--jq ".[] | select(.created_at != null) | {repo:\"$R\", n:.number, created:.created_at}" >> "$TMP/open.jsonl" 2>/dev/null || true
scripts/sli-report.sh:152
- 审计验收要求 issue 中的样本 PR 可直接打开，但这里只写
repo#n，没有 owner 或/pull/URL；在.github仓库中这不是稳定的跨仓 PR 链接，审计人无法可靠跳转。请输出完整的 PR URL 或规范的跨仓引用。
print(f"SAMPLE={s['repo']}#{s['n']} {s['title'][:60]}")
scripts/sli-report.sh:198
- 审计 issue 创建失败这里只递增
INFRA，后面没有检查INFRA，所以周报可能成功但缺少必需的审计 issue，脚本仍以 0 退出。该失败应直接终止或在最终退出前 fail-closed。
发现回流：归因后回写 SLI 指标，必要时开门禁补强 issue。（#98，ADR-0059）" || infra "审计 issue 创建失败"
scripts/sli-report.sh:20
- 这里宣传了
SLI_FIXTURE_DIR和SLI_EXPECT_*注入，但脚本没有读取这些变量或 fixture 文件；自测始终使用硬编码数据，无法按文档回放 T2/T5 fixture。请实现注入契约，或删除该用法说明。
# 注入（T2/T5 离线）: SLI_FIXTURE_DIR=<dir>（PR/issue JSON 文件）+ SLI_SAMPLE_SIZE + SLI_EXPECT_* 断言
scripts/sli-report.sh:148
human_touches在本脚本自己的指标契约中已定义，但输出从pr_duration_p95直接跳到flaky_rate，没有计算或报告该指标；#98 要求的人工触碰数因此缺失，而不是像 flaky/entropy 那样明确 pending。请补上 reviews/comments/manual merge/rerun 的数据采集与分母。
print(f"auto_merge_rate={rate} ({len(agent_merged)}/{len(merged)})")
print(f"escape_rate={esc} (reverts={rev}+p0={p0} / merged={len(merged)})")
print(f"stuck_prs={len(stuck)} (>{stuck_h}h)")
print(f"pr_duration_p95={p95}")
print(f"flaky_rate=pending（#94 数据源滚动）")
scripts/sli-report.sh:183
- 报告 body 只写当前指标和“本期”阈值状态；虽然读取了
PREV仅用于升级判定，却没有输出上一期值或任何周环比。#98 的执行要求是周报包含 week-over-week 对比，请在报告中呈现至少当前/上期值及变化，或明确补齐该数据源。
阈值状态：escape_rate 连续两周>0 → P1 升级（本期：$ESCALATE）
scripts/sli-report.sh:119
- open PR 列表拉取失败被
|| true完全吞掉；随后stuck_prs会把缺失数据当成空列表，可能错误报告为 0。对 SLI 采集来说这不是可忽略的单仓故障，应 fail-closed。
--jq ".[] | select(.created_at != null) | {repo:\"$R\", n:.number, created:.created_at}" >> "$TMP/open.jsonl" 2>/dev/null || true
scripts/sli-report.sh:29
- 这些治理参数没有从声明的 policy 读取；当前
governance/policy/automation-limits.yaml也没有sli节。这样调整窗口、抽样数或阈值只能改脚本，与 workflow 所称的“真源”不一致，后续容易造成口径漂移。
WINDOW_DAYS="${SLI_WINDOW:-7}"

PREVselects the newestsli-reportissue without checking its ISO week. A repeated/manual run in the same week can treat the first report from that same week as the previous week and trigger P1 after two positive runs, even though the two-week condition is not met. Persist/query the report week and require a distinct prior ISO week.

scripts/sli-report.sh:1
- The gate's shell syntax step explicitly lists the scripts it checks (
.github/workflows/gate.yml:86-92) and does not include this new C1 script. A syntax error insli-report.shcan therefore merge without PR validation; add the script to the gate's syntax check (and run its offline self-test there if it is a required guardrail).
