why.whitespace

You piped the field in and something kept a trailing space, or the value came out of a variable that had one on the end.

What it means

Leading or trailing whitespace around the field, which the door refuses rather than trimming: nothing here silently rewrites text it did not author.

The mechanical pass reaches it: roadkeep lint --fix closes this one.

What closes it

• roadkeep lint --fix — the field is trimmed where it already sits, and no other byte moves
