Struct HistoryEntry 

pub struct HistoryEntry {
    pub commit: u64,
    pub change: HistoryChange,
}

A single change event in a node’s history, paired with the WAL commit that produced it.

Horizon

History reaches back only to the last WAL-truncating snapshot, exactly like open_at. Snapshots written with keep_wal: true preserve deeper history. This is the honest, zero-cost contract; a durable history log is out of scope.

Derived edges

Rule-created (derived) edges are not in the WAL and therefore do not appear in history. Only edges written directly by the application are recorded.

Fields

commit: u64

0-based WAL frame index of the commit that produced this change.

change: HistoryChange
