Struct GraphCheckpointRecord 

pub struct GraphCheckpointRecord {
    pub name: String,
    pub mode: String,
    pub snapshot: GraphPersistSnapshot,
    pub seq: u64,
    pub timestamp_ns: u64,
    pub format_version: u64,
}

Portable baseline record written by attach_snapshot_storage on full-snapshot writes. Contains the full GraphPersistSnapshot plus metadata for WAL cursor alignment.

The format_version field closes F7 (missing format_version on WALFrame and checkpoint records).

Fields

name: String

Graph name (matches snapshot.name).

mode: String

Snapshot mode — "full" for baseline, "diff" reserved for future incremental baselines.

snapshot: GraphPersistSnapshot

The complete graph state.

seq: u64

WAL-tier cursor at baseline write time. Frames with frame_seq > seq are the delta.

timestamp_ns: u64

Wall-clock timestamp at baseline write time.

format_version: u64

Format version (F7 close).
