D-227: records the two-tier driver model (body envelope from authored
params only, D-240 tilt exclusion upheld; position tier with fjord/
latitude/wetness/heterogeneity), the shared invent_primitives path,
the scatter floor-vs-ceiling reading, shoreline carving, and the
one-step-stale circularity ruling. D-239: Marine appended at
discriminant 6, morphology-derived verdict, airless precedence,
non-semantic Ord position.
