Struct SetFormatVersionPayload 

pub struct SetFormatVersionPayload {
    pub target: u8,
    pub gated_members: BTreeSet<u64>,
}

Payload of HighWaterCommand::SetFormatVersion: the committed activation barrier that flips the cluster’s active write version.

gated_members is the exact member set (voters ∪ learners) the leader’s activation gate observed as capable of reading target at proposal time. It travels inside the entry because the state-machine apply cannot perform a live capability query; apply re-validates that the membership committed as of this entry’s own log position is a subset of gated_members before taking effect. NodeId is u64 (the type config’s Node id type), so the set is BTreeSet<u64> — a deterministic, ordered, postcard-stable layout.

Fields

target: u8

The active write version to flip to on a successful (non-no-op) apply.

gated_members: BTreeSet<u64>

Voters ∪ learners the leader gated as target-readable at proposal time.
