-r"""Tests for ExecTool safety guard — format pattern false positive.
-
-The old deny pattern `\b(format|mkfs|diskpart)\b` matched "format" inside
-URLs (e.g. `curl https://wttr.in?format=3`) because `?` is a non-word
-character, so `\b` fires between `?` and `f`.
-
-The fix splits the pattern:
-  - `(?:^|[;&|]\s*)format\b`  — only matches `format` as a standalone command
-  - `\b(mkfs|diskpart)\b`     — kept as-is (unique enough to not false-positive)
