Pull request overview
Updates the suppression-gate workflow to move detector and ADR artifacts outside the scanned workspace. Generated pr.diff, pr-title.txt, and pr-body.txt remain in the workspace and may still cause false positives.
Changes:
- Relocates detector and ADR files to
RUNNER_TEMP. - Removes workspace checkout artifacts.
- Updates related command paths.

修正步骤名称的 YAML 折行。
Line 81-82 是 YAML 注释，不是 name 的续行。工作流界面只会显示截至“检测器”的文本。请使用 name: >-，或将完整名称写在一行。

🌐 Web query:
actions/checkout repository input ref omitted default branch cross-repository checkout documentation
💡 Result:
When using the actions/checkout action, the behavior of the ref input depends on whether the repository being checked out is the same one that triggered the workflow. If you omit the ref input, the action's behavior is as follows: 1. Workflow Repository: If you are checking out the repository that triggered the workflow (the default behavior if the repository input is also omitted), the action defaults to the reference (branch, tag, or SHA) that triggered the event [1][2][3][4]. 2. Cross-Repository Checkout: If you specify a different repository using the repository input (e.g., repository: owner/repo) and omit the ref input, the action defaults to that repository's default branch [1][2][3][4]. In summary, when performing a cross-repository checkout without an explicit ref, the action will always target the default branch of the specified repository [1][3].

将 ADR checkout 固定到 main。
actions/checkout 跨仓且未设置 ref 时会使用目标仓库的默认分支。当前默认分支虽为 main，但该行为不满足策略中“ADR 检出面为 main”的固定契约。若默认分支变更，未合入的 ADR 可能进入 escape hatch 并绕过 suppression gate。

1. Implicit temp-dir dependency 🐞 Bug ☼ Reliability
The “ADR 清单就位” step assumes $RUNNER_TEMP/adr was created by an earlier step; if that earlier step is reordered/edited/conditionalized, the cp will fail and the gate will break even though ADR checkout succeeded.
Agent Prompt
### Issue description
The workflow step `ADR 清单就位（同款拷出即删）` copies into `"$RUNNER_TEMP/adr/"` but does not ensure the directory exists. It currently relies on a previous step to create it, which is fragile and can break if the workflow is refactored.
### Issue Context
This is a reliability/maintainability issue in the workflow logic: a future re-ordering or conditional change could cause `cp -r ... "$RUNNER_TEMP/adr/"` to fail.
### Fix Focus Areas
- .github/workflows/suppression-gate.yml[120-124]
### Proposed change
In the `ADR 清单就位` step, add `mkdir -p "$RUNNER_TEMP/adr"` before the `cp -r ...` line so the step is self-contained.

v1.5.8 实测（Use-up-Plan PR#61 T1-P-B 注入）：suppression-gate 的 ciw-sup/adr-src 检出留在工作区，总量维度把检测器自带 fixture 标记计入被审树 → total=34 vs 基线 0 误报。此前 7 仓 re-pin PR 靠 ADR-0036 逃生门豁免通过（豁免日志自证），掩盖了误报——不修则所有仓下一个无 ADR 引用的 PR 必误红。
