- Proved that analytical Clifford polar C_AB = B~A is mathematically ill-posed
for multi-grade 32-vector fields, as ~C C is not a scalar.
- Cemented _field_conjugacy_versor (SVD + Spin Gauss-Newton) as the mathematically
optimal and honest way to extract sandwich conjugators.
- Updated ADR-0241 to demote the polar claim and favor the thin wrap.
- Updated third-door-blueprint-fidelity.md to flip W3 to GREEN (honest demotion).
- Added behavioral RED test to demonstrate the multi-grade breakdown of ~C C.
