Emits Domain.registered.
Performed by the Integration Engineer.
One-way (money): it waits out its delay window, and runs in the send and do modes.
Renews the registration before it expires, as spend under the Startup’s Limits.
Checks the spend Limit; above it, opens an Approval.
Refuses on a provisional self-serve Startup; the name stays a candidate until Startup.claim.
Registers the name to the owner of record, in the Startup’s own registrar account, with DNSSEC and a CAA record.
Writes null SPF, DMARC reject and null MX records unless the Domain hosts a Mailbox.
Registers the Domain with Stripe as a payment method domain on the Startup’s account.

Check	Error	Fix	Then call
The operation is part of an Offer the caller has not accepted or paid for.	`payment-required`	Accept the Offer named in the response, then retry the call.	Offer.accept
The key is valid, but its scopes do not allow this operation.	`forbidden`	Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them.	Domain.register
The record changed since it was read, so the write would overwrite a newer version.	`conflict`	Read the record again, then retry the write against its current state.	Domain.register

Gate	Default
Decision class	Medium: one-way, bounded (money)
Delay window	1 business hour, in which a watcher can pause, redirect or cancel it; then it runs.
Limit	The spend Limit of the Permission or Mandate it runs under.
Over the Limit	It waits `pending` for an Approval from the Founder. Approved, it runs; refused, it ends `refused` with `limit-exceeded`; unanswered by its deadline, it ends `canceled`.
