Root cause: dr-translator was trying to write entire final_zh.md in one write call, hitting Sonnet 4-6 output token limit for long reports (~19k English words → ~27k Chinese chars → blown past 32k token cap). Fix: explicit chunk-and-append protocol - Split final_en.md by H1 (# ) then H2 (## ) boundaries - Each chunk ≤ 2,500 English words - First chunk uses write to create final_zh.md - Subsequent chunks use edit or read+write to append - Per-chunk Chinese output kept under ~5,000 characters (safe margin) - Preserves glossary.json updates across chunks
