v8.0.2

Fixed

• The six compound tools published an empty input schema. Their z.union
  of per-mode objects serialized to {"type":"object","properties":{}} — the
  SDK only converts object schemas and raw shapes to JSON Schema, and a union
  is neither — so an Apps host had no fields to render a form. The compound
  layer now registers a flat shape: the mode enum plus every field each mode
  accepts, unioned where a name is shared across modes (e.g. species is a
  string in lookup/species and an array in lookup/sprites), with the
  per-mode object re-enforcing the real required-field contract inside the
  handler. The smoke suite pins that every compound tool publishes its mode
  enum and fields.
