Struct MigrationRecord 

pub struct MigrationRecord {
    pub node_id: String,
    pub children_bytes: Vec<u8>,
}

A single graph node record in the canonical migration format.

All BEAM storage backends store the same logical data — a node_id mapped to a Children map. The on-disk encoding varies (bare bytes vs. NodeRecord-wrapped, string keys vs. prefixed keys), but the semantic content is identical.

This struct is the “lingua franca”: every reader produces Vec<MigrationRecord>, every writer accepts &[MigrationRecord]. The children_bytes field is always postcard(Children) — the bare serialized form that redb and fjall store directly, and that persy wraps in [NodeRecord].

Fields

node_id: String

The graph node identifier (e.g. "users/alice", "" for root).

children_bytes: Vec<u8>

Bare postcard(Children) bytes — the universal value format.
