Building tracked-changes + DOCX round-trip on Lexical with Yjs

[fangrayshin11-cmyk]

Hi Lexical team! My team is trying to build an academic copy-editing platform and evaluating Lexical. We need:

• Suggestion/track-changes with accept/reject, per-author attribution, and a revision history view
• Real-time collaboration (Yjs) for long docs (10–50k words) with many comments; tips for batching/history/GC
• DOCX ↔ HTML round-trip (docx→HTML→Lexical and back) and any style-mapping gotchas you consider out of scope
• Versioning/audit: tag each operation as human vs machine for a transparency report

Environment: React 18, Lexical (latest), Yjs (custom provider), Pandoc/Mammoth for conversion (TBD).

So questions: recommended patterns/examples for suggestion mode & diff/merge? limits/caveats for very large docs with Yjs? schema tips that help clean DOCX export later?
