Fill-Protocol Skill

Core Principles (Do Not Violate)

1. Open the existing template — never create from scratch. Use Document(template_path), not Document(): rebuilding loses the header logo, custom margins, footer placeholders and page numbering. Replace cell/paragraph text in place; never a single cell.text = "value" assignment, which erases run-level styles (bold, color, eastAsia font).
2. Convert .doc → .docx via LibreOffice headless before any editing. pandoc -f doc is not supported; textutil corrupts table structure (merged cells dropped).
3. Match cells by left-label text, not row/column coordinates such as table.cell(2, 1). Templates evolve and coordinate matching breaks silently.
4. Apply cantSplit to every filled row so a row never breaks across pages.
5. For CJK languages, set the eastAsia font attribute, not just run.font.name, or Hangul/Kanji/Hanzi render in fallback fonts.
6. Validate every fill operation: resolve every [MISS] line and every WARN: line ([TABLE-MISS], [SECTION-MISS], [RAW-NEWLINE]) before the filled form is submitted.
