(:op "layout" :type T) needs no running program: the daemon owns the build, so
Tast.structs is already in the session it compiled the process from. The open
question was what T is, and it needs no new machinery — Load qualifies every
declaration at import, so two packages' Missing are a/Missing and b/Missing and
the name is the type id. Emit already writes that same qualified name into
flan_error, so the string break reports as :condition resolves as :type by
construction, which is the round trip the test makes.
A bare name is refused with the candidates rather than resolved to a unique
suffix: resolving it would put back the ambiguity the rule exists to remove.
