- Coarse/fine name the two members of any pair (Hierarchy docstring); only the
misleading blocked_base_tables -> blocked_coarse_tables. prepare_fine_boundary
and blocked_fine_tables keep their pair-relative names.
- Depth-1 static circles use the integer-NODE frame (unchanged behavior); the
root EDGE frame applies to refined levels only. Contract text corrected.
- _kernel_configs documents why it stays distinct from Hierarchy.configs.
- Drop the stale re-export comment; two tests import table builders from
refinement_tables. Mechanical caller renames for this delta only.
No numerical code or config derivation changed.
