Expand description

Graph operations — the payload of each Merkle-DAG entry.

DefineOntology must be the first (genesis) entry. All subsequent operations are validated against the ontology it defines.

Variants§

§

DefineOntology

Genesis entry — defines the initial ontology (extendable via R-03 ExtendOntology). Must be the first entry in the DAG (next = []).

Fields

§ontology: Ontology
§

AddNode

Fields

§node_id: String
§node_type: String
§subtype: Option<String>
§label: String
§properties: BTreeMap<String, Value>
§

AddEdge

Fields

§edge_id: String
§edge_type: String
§source_id: String
§target_id: String
§properties: BTreeMap<String, Value>
§

UpdateProperty

Fields

§entity_id: String
§value: Value
§

RemoveNode

Fields

§node_id: String
§

RemoveEdge

Fields

§edge_id: String
§

ExtendOntology

R-03: Extend the ontology with new types/properties (monotonic only).

Fields

§

Checkpoint

R-08: Checkpoint entry — summarizes all prior state. Contains synthetic ops that reconstruct the full graph when replayed. After compaction, this becomes the new genesis (next=[]).

Fields

§ops: Vec<GraphOp>

Synthetic ops that reconstruct the graph state

§op_clocks: Vec<(u64, u32)>

Per-op clocks: (physical_ms, logical) for each op. Bug 6 fix: preserves per-entity clock metadata for correct LWW after compaction.

§compacted_at_physical_ms: u64

Physical timestamp when compaction was performed

§compacted_at_logical: u32

Logical timestamp when compaction was performed
