 ## Decision
 
-The root `change-scope` command requires `--base <ref>`, accepts `--head <ref>` with `HEAD` as the default, and offers a versioned `--json` form. It resolves both inputs to commits with ambiguity detection and requires one merge base before writing output. The report records the repository root, current branch, configured upstream, input refs, resolved base, head, and merge-base commit IDs, plus sorted committed, staged, unstaged, and untracked path sets.
+The root `change-scope` command requires `--base <ref>`, accepts `--head <ref>` with `HEAD` as the default, and offers a versioned `--json` form. It resolves both inputs to commits with ambiguity detection and requires one merge base before writing output. The report records the repository root without normalizing legal path whitespace, current branch, configured upstream, input refs, resolved base, head, and merge-base commit IDs, plus sorted committed, staged, unstaged, and untracked path sets.
 
 Committed paths compare the resolved merge base with the resolved head. Dirty path sets always describe the current worktree and index, even when `--head` names another commit. Diff configuration cannot hide submodules or invoke external diff or text-conversion drivers, and rename detection is disabled so both sides of a rename remain visible.
 
 The command never guesses or fetches a base, queries a hosting provider, or selects tests. Each calling workflow verifies current remote or stack state, supplies the base explicitly, and uses the factual report as input to semantic review or evidence selection.
 
-Focused temporary-repository tests cover a fresh branch tracking `origin/master` without a same-name remote, its post-push upstream, a stacked non-master base, every dirty layer, invalid, ambiguous, and non-commit refs, deterministic human/JSON parity, and unchanged refs, index, config, and status after reporting.

 ## 决策
 
-根目录的 `change-scope` 命令要求提供 `--base <ref>`，接受可选的 `--head <ref>`（默认为 `HEAD`），并提供带版本号的 `--json` 输出格式。该命令会检测歧义，将两个输入解析为 commit，并要求二者恰好有一个合并基点，之后才会输出结果。报告记录仓库根目录、当前分支、配置的上游、输入引用、解析后的基准、头部与合并基点 commit ID，以及排序后的已提交、已暂存、未暂存和未跟踪路径集合。
+根目录的 `change-scope` 命令要求提供 `--base <ref>`，接受可选的 `--head <ref>`（默认为 `HEAD`），并提供带版本号的 `--json` 输出格式。该命令会检测歧义，将两个输入解析为 commit，并要求二者恰好有一个合并基点，之后才会输出结果。报告记录仓库根目录（不对路径中的合法空白字符作规范化处理）、当前分支、配置的上游、输入引用、解析后的基准、头部与合并基点 commit ID，以及排序后的已提交、已暂存、未暂存和未跟踪路径集合。
 
 已提交路径由解析后的合并基点与头部之间的比较得出。即使 `--head` 指定其他 commit，各类未提交路径集合仍始终描述当前 worktree 与索引。diff 配置不能隐藏子模块，也不能调用外部 diff 或文本转换驱动；系统禁用重命名检测，因此重命名前后的路径都会保留在结果中。
 
 该命令从不猜测或获取基准，不查询代码托管提供方，也不选择测试。调用该命令的每个工作流都会验证当前远端或堆叠状态、显式提供基准，并将这份事实报告作为语义评审或证据选择的输入。
 
-聚焦的临时仓库测试覆盖以下情形：新分支跟踪 `origin/master` 但没有同名远端分支；同一分支推送后的上游配置；堆叠分支以非 master 分支为基准；所有未提交改动层；无效、有歧义及不指向 commit 的引用；人类可读输出与 JSON 输出保持确定性一致。测试还确认生成报告前后，引用、索引、配置与状态均不发生变化。
