The verification object embedded in a Stripe Tax ID.
Reachable from LatticeStripe.TaxId.t/0. :status is the field to match on before
trusting a customer-supplied tax ID — see the Tax guide for the full status set and
what each one means for invoicing.
This struct holds PII. :verified_name and :verified_address are redacted in
Inspect output to keep them out of logs and IEx sessions; read them explicitly by
field when you need them.
Embedded value struct: fields are additive. Keys Stripe adds later appear under
:extra rather than being dropped, so a new field never breaks decoding.
