Decoding Unknown Shapes Inside Known Shapes

if I have an unknown or opaque shape inside a known shape. How can I decode it correctly?

type I = {
  foo: string // known
  bar: unknown
  baz: Json // opaque
}

type A = {
  foo: string
  bar: number
  baz: { qux: "Qux" }
}

type I = {
  foo: string // known
  bar: unknown
  baz: Json // opaque
}

type A = {
  foo: string
  bar: number
  baz: { qux: "Qux" }
}

type I = {
  foo: string // known
  bar: unknown
  baz: Json // opaque
}

type A = {
  foo: string
  bar: number
  baz: { qux: "Qux" }
}

type I = {
  foo: string // known
  bar: unknown
  baz: Json // opaque
}

type A = {
  foo: string
  bar: number
  baz: { qux: "Qux" }
}
