Summary

• Add SimplifyMoveMarkup setting to convert native move markup (w:moveFrom/w:moveTo) to simple w:del/w:ins for Word compatibility
• Change DetectMoves default from true to false until Phase II fixes the underlying ID collision bug
• Phase I workaround for Issue Move operations cause Word 'unreadable content' warning #96: Move operations cause Word "unreadable content" warning

Root Cause Analysis

The underlying bug is in FixUpRevMarkIds() which runs AFTER FixUpRevisionIds() and overwrites w:del/w:ins IDs starting from 0, causing collisions with move element IDs. This will be fixed in Phase II.

Changes

• WmlComparerSettings: Added SimplifyMoveMarkup (default: false), changed DetectMoves default to false
• SimplifyMoveMarkupToDelIns(): New method that converts move markup to del/ins
• Documentation: Updated CHANGELOG.md and CLAUDE.md with warnings and usage guidance
• Tests: 7 new tests covering SimplifyMoveMarkup functionality

Usage

For users who need move detection with Word compatibility:

var settings = new WmlComparerSettings
{
    DetectMoves = true,
    SimplifyMoveMarkup = true  // Converts moves to del/ins for Word compatibility
};

Test plan

• All 7 new SimplifyMoveMarkup tests pass
• Full test suite passes (1185 passed, 0 failed, 1 skipped)
• Manual verification: Compare documents with moves, open in Word without warnings

Fixes #96 (Phase I)
