"Reachable only through a raw register() whose parameters is
array-rooted" was too narrow. A root oneOf reaches the same 182: the
union arm propagates listDepth unchanged because `A | B` opens no
bracket, so an array branch starts its chain at 0 exactly as an array
root does. Say "root opens an array chain -- rooted at the array, or at
an array branch of a root oneOf", in the JSDoc and the test comment,
and assert the union shape alongside the array-rooted one.
The note's Decision paragraph said the flavor guard is reached under
"a language that has a renderer but no flavor entry, and a test covers
it". The test uses ruby, absent from both tables, and the mechanism is
that schemas() reaches run_code's getters without passing
requireCodeRuntime -- so any language absent from the flavor table hits
it. State that instead.
The Consequences paragraph recorded the language-binding obligation as
two reads, assembly and execution. Within one projection there are more:
run_code's description and parameters getters each call
resolveFlavor(peekRuntime()) and schemaOf destructures both, so a reload
between them yields one schema whose halves name different languages.
