Enum Recovery 

pub enum Recovery {
    Retry,
    Idempotent {
        key: String,
    },
    Reconcile,
    RequiresOperator,
}

How to recover when a crash leaves an effect’s outcome unknown.

A crash between “request sent” and “response recorded” is undecidable from the journal alone. The runtime refuses to guess, so every effect states its semantics — and the default is the conservative one.

Variants

Retry

Pure read or idempotent write — safe to re-run.

Idempotent

The provider honors an idempotency key; replay reuses the same one.

Fields

key: String

Reconcile

The effect can be queried to learn whether it landed.

RequiresOperator

Undecidable. Escalate to a human; never guess.

The default for anything that mutates external state. In a regulated domain this is the correct posture, and it is the line between a durable-execution demo and something you point at an accounting ledger.
