Enum JobLifecycleState 

pub enum JobLifecycleState {
    Scheduled,
    Queued,
    Running,
    Completed,
    RetryWait,
    Cancelled,
    Dlq,
}

Canonical logical job lifecycle state.

Scheduled and RetryWait are derived from persisted state: both are stored as status = "queued" with a future run_at, but RetryWait also has prior failed attempt history. This keeps storage compact while still making lifecycle reconstruction deterministic from persisted job and attempt rows.

Variants

Scheduled

Queued

Running

Completed

RetryWait

Cancelled

Dlq
