Persistence Operations¶
Methods for saving, loading, and streaming knowledge graph state.
save()¶
Serialize the entire knowledge graph to a JSON file.
The JSON file contains the complete graph state: all nodes, edges, senses, autonomy records, co-occurrence statistics, and configuration parameters. The file is self-contained and can be loaded in a different session.
load()¶
Class method. Deserialize a knowledge graph from a JSON file.
Reconstructs the full graph state including all Rust-side data structures. The loaded instance is identical to the one that was saved.
snapshot_v1()¶
Runtime snapshot for UI consumption.
Returns a JSON string containing the current graph state in the v1 snapshot format. This is used by the frontend for 3D visualization and is designed for low-latency consumption.
consume_events_v1()¶
Incremental event stream. Returns events with sequence numbers after the specified position.
Parameters¶
| Parameter | Type | Default | Description |
|---|---|---|---|
after_seq | int | None | None | Return events after this sequence number |
limit | int | 100 | Maximum number of events to return |
Events are consumed (one-time read) from the Rust core's event buffer. Each event includes a monotonic sequence number, correlation ID, timestamp, event type, and payload.
latest_seq_v1()¶
Current monotonic event sequence number.
Use this to track the event stream position. Pass the result as after_seq in subsequent calls to consume_events_v1() to get only new events.
Event Schema¶
{
"api_version": "v8.3",
"schema_version": "v8.3",
"seq": 42,
"correlation_id": "corr_abc123",
"event_type": "node_created",
"payload": { "id": 25, "label": "batu" }
}
Event Types¶
| Type | Trigger | Priority |
|---|---|---|
node_created | New node inserted | normal |
confidence_changed | Confidence updated | low |
tier_changed | Tier promoted/demoted | low |
status_changed | Status transition | low |
edge_created | New edge added | low |
