Underwriting runs inline, so the response already carries the decision. On approval
the facility comes back APPROVED with its credit_limit, CLC has registered the
lien and set the required-collateral floor, and the borrower can draw against it.
On a decline it comes back DECLINED with a decline_reason. Nothing further is
required of you either way.

CLC also emits facility.decisioned for the same decision, so a consumer that
only listens to webhooks stays in sync. It carries no information the response did
not already give you.

Requires scope facility:create and an ELIGIBLE borrower.
