DESTRUCTIVE_SQL_DD shared one trailing \b across every alternation arm. `dd\s+if=` ends in `=`, and a \b after a non-word character only holds when the NEXT character is a word character, so the arm matched `dd if=x` and missed every path starting with `/`, `.` or a quote: dd if=/dev/zero of=/dev/sda allowed dd if=./disk.img of=/dev/sdb allowed dd if="/dev/zero" of=/dev/sda allowed The word-boundary suffix now applies only to the arms that end in a word character. The split is what keeps the widening bounded: dropping the trailing \b outright would let `truncate` match `truncated`, and dropping the leading \b would let `dd if=` match inside `add if=`. Both are covered. This is the half of #2642 that survived the structural findGitSubcommand() parser, which already handles `git checkout -- .`. Not addressed here: `dd of=/dev/sda if=/dev/zero` with the operands reversed is still allowed, before and after, because the pattern requires `if=` immediately after `dd`. That is a different defect from the boundary bug and widening a P0 gate's pattern shape is a maintainer call. Refs #2642
