# Case: `council-report-defaults-to-consensus-when-run-is-only-unanimous`

## 用例意义

验证当 council run 以 `--only-unanimous` 启动时，省略 `--show` 的 `council report --json` 默认只返回 `consensus` bucket。

## 前置条件

- 使用隔离的临时目录 `TMPDIR`
- 已准备好与 `council-report-defaults-to-consensus-and-majority` 相同的 3 份 reviewer 输出 JSON
- 本地可使用 `sqlite3` 从 `task_attempts` 中读取 reviewer thread ID

## 输入

```

## 预期输出

- 最后一条 `council report` 命令退出码为 `0`
- `ok == true`
- `data.run_id == "council_blog_report_011"`
- `data.show == ["consensus"]`
- `data.summary.consensus == 1`
- `data.summary.majority == 1`
- `data.summary.minority == 1`
- `data.grouped_recommendations` 长度为 `1`
- 唯一返回的 recommendation 的 `bucket == "consensus"`

## 断言结论

- `--only-unanimous` 不会删除持久化的 `majority` 或 `minority` 数据，但会改变省略 `--show` 时的默认输出策略
- leader 若希望在 unanimous-only run 中仍查看 `majority`，必须显式传入 `--show`

## 补充约束

- 即使这里使用 `--json` 断言 `show` 默认值，命令仍会写出 markdown artifact
