Struct BarrierAnnouncement 

pub struct BarrierAnnouncement {
    pub epoch: u64,
    pub checkpoint_id: u64,
    pub assignment_fence: Option<CheckpointAssignmentFence>,
    pub leader_proof: Option<LeaderProof>,
    pub phase: Phase,
    pub flags: u64,
}

Leader-written barrier announcement.

Fields

epoch: u64

Monotonic checkpoint ID retained in the wire field named epoch.

checkpoint_id: u64

The same nonzero coordinator-assigned checkpoint ID.

assignment_fence: Option<CheckpointAssignmentFence>

Exact clustered assignment cut captured when this attempt was admitted. Required on every clustered Prepare and retained on terminal phases for exact follower validation.

leader_proof: Option<LeaderProof>

Exact durable leader term that issued this announcement. Clustered reversible phases (Prepare and Aligned) are rejected unless this proof is present and still live. Terminal notifications carry it only for diagnostics; their authority comes from the immutable durable checkpoint outcome.

phase: Phase

Phase this announcement signals.

flags: u64

Reserved for unaligned/other flags.
