R-302 showed check-unmarked catching what check-figures misses. I had taken
that, plus a preference for structure over vocabulary, as grounds for folding
check-figures in as a secondary pass. The converse test contradicts it: five
unbolded cells in a measurement column, markers stripped, fail check-figures
and pass check-unmarked, whose strict class requires bold by design.
So the relationship is symmetric. The shapes are the weak half and should fold
in behind the structural classes; the column-header rule is not a shape and
belongs beside bold-as-published, not under it.
Also records what a merged guard must face rather than inherit: this corpus
bolds inconsistently inside tables, which is invisible to a reader and
load-bearing for a class keyed on boldness.
Both runs in throwaway worktrees, never the shared tree. No merge performed;
the decision sits with the humans.
