Sharpen the glossary to decouple deterministic old-schema re-mapping from
neighbour-prediction gap-fill (a separate, unimplemented ML path), and add
the Reduced-Field Synthesis term. ADR-0027 records the pre-SAP10 20.0.0
mapper's best-attempt synthesis (corpus-fit glazing 0.148xTFAxband, 4-way
orientation) and its trade-offs. Grill resume doc captures every resolved branch.
