매개변수 제약
KinsokuRules is an explicit choice of boundary policy. AtlasDefault retains its fixed Atlas punctuation sets and context checks. It does not acquire new Unicode rules when the host changes.
Unicode16Ko, Unicode16Zh, and Unicode16Ja use the ordered Unicode 16.0.0 UAX 14 revision 53 decisions. They retain non-tailorable prohibitions, mandatory breaks, and required opportunities before locale and custom typography rules.
The Korean policy applies KLReq punctuation and fitting Hangul word handling. The Japanese policy applies strict JLReq kinsoku including small kana and numeric prefix and suffix contexts. The Chinese policy applies CLReq basic punctuation handling. The exact versioned character predicates are the referenced policy definitions.
Unicode policies reject a cluster that crosses a mandatory line break with TypesetError.InvalidInput. A mandatory break after an intact cluster is a ForcedEnd opportunity even when more clusters follow. A cluster boundary inside a forbidden Unicode sequence is not an opportunity.
LatinSpace marks an admitted boundary after a cluster whose text is U+0020. LatinHyphen marks an admitted boundary after an existing hyphen cluster. LatinSoftHyphen marks an admitted generated hyphen candidate. Neither category inserts a character into the input.
ClosingPunctuation marks an admitted boundary after the selected closing-punctuation category. CjkCluster marks the admitted CJK or East Asian cluster category. HardFallback marks another admitted boundary or a permitted emergency word boundary. These categories do not authorize a break excluded by the selected policy.
ForcedEnd marks the paragraph end or a mandatory Unicode boundary. BreakRule.Forced is the distinct planning constraint that prevents a plan from crossing that position. A ForcedEnd category on a caller-created penalty does not replace its BreakRule.
For Unicode candidates, mandatory boundaries are classified first, followed by space, existing hyphen, closing punctuation, CJK or East Asian text, and HardFallback. Generated hyphens replace a missing or HardFallback category when admissible. Output ordering follows the cluster indices rather than category order.

이유
A locale policy decides whether a boundary can be used. A category tells the planner why that admitted boundary exists. Keeping those roles distinct lets the same paragraph model carry Unicode, locale, and caller-supplied constraints without treating a punctuation label as permission.
