Enum TransientCause 

#[non_exhaustive]
pub enum TransientCause {
    PasServerError,
    CipherEncryptFailed,
}

Why a liveness attempt was classified transient.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PasServerError

PAS is unreachable: a 5xx response, an HTTP transport failure (timeout, TLS, DNS, connect), or a 2xx body that failed to parse (CDN/proxy interference). All three categories are indistinguishable at the policy level (S-L3 serves cache for every one of them) — the variant name is a deliberate simplification carried over from v3 where each had a separate cause variant; v5.0 merged them.

Detail strings carrying the underlying PasFailure::Transport or PasFailure::ServerError message are not exposed here — consumers needing that level of diagnostic should implement PasAuthPort and log inside the adapter.

CipherEncryptFailed

Re-encrypting a rotated refresh_token failed after PAS already confirmed liveness. Local infrastructure issue; the previously stored ciphertext remains valid.
