/**
 * Tell apart the two transport failures the outcome contract names, from any
 * call the journey makes itself (FDEL-53728 Q2).
 *
 * `session_expired` and `network` were in the contract, and `resultScreen.ts`
 * had copy for both, but nothing produced them: a submit failure collapsed into
 * `submit_failed` and every other call into `error / internal`. So a host could
 * not tell an expired session (re-authenticate) from a dropped connection
 * (worth retrying) from a genuine fault — and the *same* 401 was reported two
 * different ways depending on which call happened to hit it.
 *
 * Both are readable off the error. `FrankieApiClient`'s response interceptor
 * rethrows a plain object — NOT an `Error`, and NOT a `OneSDKError` — shaped
 * `{ message, response: { status, data } }` (`FrankieApiClient.ts:43-53`). A
 * 401 is the expired session. An axios error that never received a response
 * leaves `status` undefined, which is the network.
 *
 * Returns `undefined` for anything else, so an unfamiliar failure keeps its
 * caller's own fallback and stays diagnosable rather than being reported to the
 * host as connectivity.
