Pointing someone at “the part that breaks” is useless without coordinates, and plain-text has none. Editors show line numbers; anything pasted into a chat loses them. Adding the numbers back makes the reference stick.
Prepend sequential numbering to every line with configurable padding and a separator, so the column stays tidy at any line count. It is the polite way to share logs, config, and rough drafts you intend to discuss line by line.
