name: integer-code-modular

# Identical to integer-code except that values are zero-based ("0".."99"), so
# `x <- (x + d) mod 100` renders truthfully: the surface value of index i is
# literally i. Use this formatter whenever `solvable` is among an experiment's
# generation.families; render the other families with it too when the four
# classes should share a value vocabulary.
