Whitespace you cannot see
Trailing spaces survive a copy into Genius without ever being visible in the editor. Removing them changes nothing a reader can see, and the parser already treats a whitespace-only line as a blank one, so no section boundary moves.
Convention: No doubled spaces or hidden characters.
Example
[Verse]
A lyric In the workbench this reads: This line ends with invisible whitespace.
[Verse]
A lyricThe fix
In the workbench this finding carries one control, labelled Remove trailing whitespace. The fix is classified as safe, so pressing it applies the edit directly: one press, one undo step.
The convention and its limits
This check detects the pattern shown above. An accepted example passes this check; it is not a review of the whole transcription.
