Reading the wheel. I sits at the centre and is the only symbol that is not a verb —
it is the referent the other twelve act upon. Each triad is one thing you can do to it. Box area is share of all
AST nodes; the year and the name under each box are when the operation entered the language and who put it
there.
The triads are not balanced, and that is the finding. DESIGNATE alone is 53.55% — over half of everything a program does is saying which one. BIND, DECIDE and TRANSFORM split the remaining 29.71% almost evenly at 11.13, 7.78 and 10.80. Naming dominates doing by nearly two to one.
Lovelace holds six of the twelve and one seat in every triad. DESIGNATE, BIND, DECIDE, TRANSFORM — she has at least one in each. No other contributor appears in more than two. That is what completeness looks like measured rather than asserted: not the largest share, but presence in every operation class, in 1843, with no machine.
AMBER on the triad assignment — the grouping is a reading. The counts, years and attributions are LIT. First formal appearance is the attribution rule, and the Frege/Church boundary is arguable.
