# content, real coupling for no real benefit here), but the mistakes
# that would actually break a load: bad YAML, missing `id`/`name`,
# duplicate `id`s, and unknown requirement `type`s. Uses `yq` (the
# jq-wrapping kislyuk/yq, not the Go mikefarah/yq) so every check is a
# real jq filter, not bespoke parsing.
