No model. A subfolder/frontmatter wing must be a plain name of an existing wing
and then places; conflicting signals and client-marker text park; everything
else goes to the default wing. Wings are read from disk per decision.
Mutation-checked.

Explicit subfolder/frontmatter wins; otherwise a classifier and an
independent scorer must agree above a threshold on a known, eligible wing.
Anything else is an Exception for a human. Never creates a wing, never
assigns an ineligible (client/untagged) wing. Mutation-checked: dropping the
eligibility, known-wing, scorer, threshold or conflict check fails a test.
