Enum FenceDecision 

pub enum FenceDecision {
    Proceed,
    AlreadyCommitted {
        committed_op_id: String,
    },
    StaleEpoch {
        claimed_epoch: u64,
        current_epoch: u64,
        current_holder: Option<String>,
    },
    NotHeld {
        claimed_epoch: u64,
    },
}

The fence verdict for one dispatch attempt.

Variants

Proceed

The oracle shows no prior commit AND the caller still holds the lease at the claimed epoch — the side effect may run. This is the ONLY verdict that authorizes an external write.

AlreadyCommitted

The durable idempotency oracle already holds a committed record for (agent_id, run_id) — the run executed (here or on another site) and must not run again. Fence-independent: returned whatever the epoch.

Fields

committed_op_id: String

The op_id of the committed oracle record (for logging / dedup).

StaleEpoch

The caller is no longer the current holder at the claimed epoch — a stale zombie. Do not execute; re-acquire or stand by.

Fields

claimed_epoch: u64

The epoch the caller believed it held.

current_epoch: u64

The coordinator’s current epoch (0 if unheld).

current_holder: Option<String>

The device that currently holds the lease.

NotHeld

No lease is held for this agent at all (never acquired, or released). Not authorized to execute a leased side effect.

Fields

claimed_epoch: u64
