WCAB 0.7.0
WCAB 0.7.0 adds a deterministic array-formula semantic transition: the same =LEN(Inputs!A1:A3) anchor and stored B1:B3 range move from fixed legacy CSE to dynamic-array mode through inspectable OOXML metadata.
The fixture never evaluates a formula or predicts a spill extent. Its validator checks the raw cm cell-metadata binding and XLDAPR fDynamic=true record, while the FormulaFence reference adapter requires the exact FF018 mode transition and range.
Validation: 22 cases, 24 declared facts, 32 tests on Python 3.12 and 3.13, hosted CI on 3.10 and 3.13, and a fresh Python 3.12 wheel validation. FormulaFence maps 23 of 24 facts and all three coverage disclosures; the documented structural rewrite remains intentionally unmapped.
