 - 本轮补充：Grep 常用布尔参数继续补齐 ripgrep 长参数 aliases，覆盖 `--line-number`、`--ignore-case`、`--fixed-strings`、`--word-regexp`、`--invert-match` 和 `--only-matching`，并兼容 quoted semantic boolean。
 - 本轮补充：Grep multiline 搜索现在支持 ripgrep 风格 `-U`、`--multiline`、`multiline-dotall` 和 `--multiline-dotall` aliases，统一映射到既有跨行 dotall 匹配逻辑并兼容 quoted semantic boolean。
 - 本轮补充：Grep 搜索现在支持 `no_ignore`/`noIgnore`/`no-ignore`/`--no-ignore`，可跳过 `.gitignore`/`.ignore`/`.rgignore` 规则，同时继续排除 VCS metadata 目录并保留 Read deny 额外 ignore 保护；`--no-ignore` 兼容 quoted boolean。
-- 本轮补充：Grep 搜索现在支持 ripgrep 风格 `ignore_files`/`--ignore-files` 与 `no_ignore_files`/`--no-ignore-files` aliases；`--no-ignore-files` 只跳过 `.ignore`/`.rgignore`，保留 `.gitignore` 规则继续生效，并兼容 quoted boolean。
+- 本轮补充：Grep 搜索现在支持 ripgrep 风格 `ignore_dot`/`--ignore-dot` 与 `no_ignore_dot`/`--no-ignore-dot` aliases；`--no-ignore-dot` 只跳过 `.ignore`/`.rgignore`，保留 `.gitignore` 规则继续生效，并兼容 quoted boolean；既有 `no_ignore_files`/`--no-ignore-files` 保留为同路径兼容输入。
 - 本轮补充：Grep 搜索现在支持 ripgrep 风格 `ignore_vcs`/`--ignore-vcs` 与 `no_ignore_vcs`/`--no-ignore-vcs` aliases；`--no-ignore-vcs` 只跳过 `.gitignore`，保留 `.ignore`/`.rgignore` 规则继续生效，并兼容 quoted boolean。
 - 本轮补充：Glob/Grep 层级 ignore 文件现在支持 ripgrep 专用 `.rgignore`，并和 `.gitignore`/`.ignore` 共享解析、否定规则和目录规则语义。
 - 本轮补充：Grep 的 `files_with_matches` 输出现在按官方行为使用文件修改时间倒序排序，mtime 相同再按路径排序；分页和 `head_limit` 会在排序后应用。

 - `Grep` long-line output now accepts `max_columns_preview`/`--max-columns-preview` plus `no_max_columns_preview`/`--no-max-columns-preview`, showing a ripgrep-style truncated preview when `max_columns` is exceeded.
 - `Glob`/`Grep` traversal now applies `Read(...)` deny rules from the permission context as extra search ignore rules, hiding denied basename, path, and directory patterns from search results.
 - `Glob`/`Grep` hierarchical ignore loading now includes ripgrep-specific `.rgignore` files in addition to `.gitignore` and `.ignore`.
-- `Grep` now accepts ripgrep-style `ignore_files`/`--ignore-files` and `no_ignore_files`/`--no-ignore-files`, letting `.ignore`/`.rgignore` rules be disabled while `.gitignore` remains active.
+- `Grep` now accepts ripgrep-style `ignore_dot`/`--ignore-dot` and `no_ignore_dot`/`--no-ignore-dot`, letting `.ignore`/`.rgignore` rules be disabled while `.gitignore` remains active; `no_ignore_files`/`--no-ignore-files` remains accepted as a compatibility alias for the same current path.
 - `Grep` now accepts ripgrep-style `ignore_vcs`/`--ignore-vcs` and `no_ignore_vcs`/`--no-ignore-vcs`, letting `.gitignore` rules be disabled while `.ignore`/`.rgignore` remain active.
 - `Read`/`Edit` now coerce quoted semantic strings for `offset`/`limit` and `replace_all`, including whole-decimal numeric strings such as `"2.0"` for integer fields while keeping fractional values rejected.
 - `Bash`/`BashOutput` now coerce quoted semantic strings for `timeout`, `run_in_background`/`runInBackground`, and `tail_lines`/`tailLines`, matching official SDK-style number/boolean inputs without relaxing unknown-field validation.
