Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.

`404`

Refusal	What it means	What to do
`ProductNotFound` productId	No such record in this organization.	Check the id in the path or the body.

`409`

Refusal	What it means	What to do
