Case contract

Input [text, width, max_lines]. Words are whitespace-separated. A word longer than width first flushes the current line, then is emitted in width-sized chunks, the final remainder continuing as an ordinary word. Words join with single spaces while the line length stays <= width. Return {"lines": the first max_lines lines, "overflow": whether more than max_lines lines were needed}.

Why this case matters

Label printers and carrier manifests cap line length and line count; an off-by-one silently truncates part of the address.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
one character over once the separator counts	`{"lines": ["ATTN ZORBLETO"], "overflow": false}`	`{"lines": ["ATTN", "ZORBLETO"], "overflow": false}`	Failed
