A read-failure primitive decided from the status alone, so a 401 from a step-up or re-proof gate would have read as an ended session and sent the reader to sign-in. The code now decides first and the status is the fallback for codes it does not know. The two invitation routes answer an unknown name or e-mail with sharing.invite.no_account. Both have a second 404 with a different next step, and since every error now carries a code the clients match on it instead of on the status. The status defaults move into a module the client can import, and the contract text no longer says these arms carry no code.

/**
|
|
* The `meta.errorCode` an error envelope carries when its route named none.
|
|
*
|
|
* `meta.errorCode` is what a client is told to branch on, and roughly half of
|
|
* the refusals in the tree carried one: the rest answered prose alone, so a
|
|
* client could branch on the code for one 404 and had to fall back to the
|
|
* status for the next. Every error envelope now has a code. A route that names
|
|
* its own keeps it; one that does not gets the status's code from this table,
|
|
* so the generic family is predictable from the status alone and a client
|
|
* never has to special-case an absent field.
|
|
*
|
|
* Deliberately coarse. These say which kind of refusal it was, never why —
|
|
* a route that has a reason worth branching on names its own code. Statuses
|
|
* not listed fall back to `http.client_error` / `http.server_error`.
