안녕하세요.
1~2글자 단어만 있는 긴 텍스트가 그래프 하나로 처리되던 문제를 8192자 절대 상한으로 막습니다.
아래는 클로드가 정리한 내용입니다.

원인
Splitter::preparePattern은 4096자를 넘긴 뒤 공백 앞 두 글자가 모두 공백이 아닐 때만 자릅니다. 자간을 띄운 PDF/OCR 텍스트나 "가 " 반복처럼 1~2글자 단어만 있으면 이 조건을 못 맞춰서 입력 전체가 그래프 하나가 됩니다.

변경
구 splitter의 n >= 8192 상한을 그대로 가져와, 8192자를 넘으면 다음 공백에서 자릅니다. 일반 텍스트는 그 전에 기존 조건으로 잘리므로 영향이 없습니다.

측정 (1MB 입력, macOS arm64, 변경 전 → 후)

입력	시간	최대 메모리	반환 뒤 잔류
"가 " 반복	3.9-5.0초 → 2.4초	약 1.37GB → 32-125MB	약 930MB → 15-85MB
자간을 띄운 문장	15.0초 → 2.3초	802MB → 137MB	596MB → 76MB

참고

• 자간을 띄운 텍스트는 8192자 경계 근처에서 결과가 조금 달라질 수 있습니다(1MB 기준 토큰 274,638 → 274,655개).
• kiwi-test 결과는 변경 전후가 같습니다(164개 통과). 실패 3개(HSDataset, HSDatasetUnlikelihoods, EncodeError)는 변경 전에도 실패하며, 모델 디렉터리를 대체해서 돌렸기 때문으로 보입니다.

---

Summary: Text of only 1-2 char words (letter-spaced PDF/OCR text) never met the 4096-char cut condition, so the whole input became one graph. This adds the old splitter's absolute limit: once n >= 8192, cut at the next space. 1MB peak memory drops from ~1.37GB to ~0.1GB; normal text is unaffected.

- Line 822: Update the span-processing logic around the 8192-character check in
KTrie so both pretokenized spans and spans consumed by preparePattern are
validated before consumption. Detect spans that cross the limit and handle them
explicitly without splitting or dropping the span, ensuring splitByTrieUsingTypo
never passes an oversized substring to buildTypoGraph.
