WCAB 0.12.0 adds governance.workbook_date_system_changed: an explicit raw workbookPr/@date1904 transition from false to true while dateCompatibility=true, a numeric date serial, its date format, and local formulas remain unchanged.

This is stored-control review evidence, not a claim about formula calculation, serial conversion, displayed dates, or Excel-client behavior. The release contains 27 deterministic cases, 29 observable facts, and 63 passing tests. FormulaFence 0.220.0 maps all 28 mappable facts, including exact FF117 date-system evidence.

Hosted validation passed on Python 3.10 and 3.13: https://github.com/SybilGambleyyu/workbook-change-benchmark/actions/runs/30758782183
