Consecutive hyphen limit: streak reset on plain break · case 05

Hyphenation stops for the rest of the paragraph after the first ladder.

Case contract

Input [words as syllable lists, width, limit]. Greedy fill with 1-unit spaces and characters. A word that does not fit may be split at the latest syllable boundary whose head plus "-" fits, only if fewer than limit immediately preceding lines ended in a hyphen and the word is not the paragraph's last word. A line ended without hyphen resets the streak; a word too long for an empty line is set alone. Return the lines.

Why this case matters

Line breaking decides where paragraphs wrap on screen and in print; a wrong decision point shifts every following line.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: streak reset on plain break	`["column", "of", "compo-", "sition", "inter-", "na-", "tional", "a", "leading", "compo-", "sition", "inter-", "na-", "tional", "setting", "line", "column"]`	`["column", "of", "compo-", "sition", "inter-", "na-", "tional", "a", "lead-", "ing", "compo-", "sition", "inter-", "na-", "tional", "set-", "ting", "line", "column"]`	Failed
