  "Coverage for `core/parse-edn` (anomaly-returning) and its boundary
   escalation through `parse-spec-file`.

   Malformed EDN is `:invalid-input` because the content is
   caller-supplied. The boundary at `parse-spec-file` rethrows as
   ex-info so existing slingshot callers keep their contract."
