Create makes a new Exposure from the inputs below. It is inherited: every Noun has get, list, create, update and delete.

Inputs

Input	Type	Required	Description
`unit`	`string`	required	What was randomized: a Visitor, a Customer, a request, or an agent choice.
`options`	`json`	required	Every Variant that was possible at that moment.
`propensity`	`number`	required	The probability the assigned Variant had, kept for later estimates.
`at`	`datetime`	required	When the unit met the Variant.
`triggered`	`boolean`		True when the unit reached the point the Variant changes.
`variant`	Variant		The Variant the Flag assigned to this unit.

Outputs

Output	Type	Required	Description
`exposure`	Exposure	required	The Exposure.

Effects

Emits Exposure.created.
Two-way: try, send, do.

Refuses when

Check	Error	Fix	Then call
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.	Exposure.create

When it waits

Gate	Default
Decision class	Low: two-way, nothing at stake
Delay window	None: it runs once review passes.
Limit	The call Limit of the Permission 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`.
