- The TokenTextSplitter was incorrectly splitting small text into multiple chunks when punctuation marks were present, even when the entire text was well below the configured chunk size. - Only apply punctuation-based truncation when the remaining tokens exceed the chunk size (tokens.size() > chunkSize). This ensures small texts remain as single chunks while preserving correct splitting behavior for larger texts.
