Enum CredentialFailure 

pub enum CredentialFailure {
    Expired {
        expires_at: u64,
    },
    SignedOut,
    StoreUnreadable,
    EnvVarMissing {
        env_var: String,
    },
    RaceRetryable,
}

Why a credential was unusable, as data — see InferenceError::CredentialUnavailable.

These need different remedies, which is the whole reason they are separated: re-authenticating fixes SignedOut and Expired, does nothing for StoreUnreadable (unlock the keychain), and is the wrong advice entirely for EnvVarMissing (set the variable). A long job that dies on one while being told to do the other is Parslee-ai/car#797.

Variants

Expired

A Parslee session existed and its access token aged out; refresh did not yield a new one. expires_at is unix seconds.

The distinguishing case from #797: the account is fine, it is the run that outlived the token. Consumers that can checkpoint should treat this as resumable-after-reauth rather than as a hard configuration error.

Fields

expires_at: u64

SignedOut

A published tombstone: no account is active. The only state that genuinely means “log in”.

StoreUnreadable

The credential store could not be read (locked keychain, helper timeout). Says nothing about whether credentials exist — notably NOT a sign-out, and re-authenticating is the wrong reflex.

EnvVarMissing

A plain env/keychain-backed provider whose variable did not resolve.

Fields

env_var: String

RaceRetryable

The store reported an active session on the failure-path re-read — a race between the two reads, so the request is worth retrying.
