Module graph 

CE-5: Memory Knowledge Graph

Persistent SQLite sidecar that stores directed edges between memories. Edge building is asynchronous (spawned tokio task) — write latency unaffected. BFS traversal targets ≤100 ms for depth ≤3 on a 1000-memory namespace.

Structs

AuditEvent

A business-event audit record.

AuditEventInsert

Insert payload (no id yet — assigned by SQLite AUTOINCREMENT).

GraphEdge

A directed graph edge between two memories.

GraphExport

Export of all graph edges for an agent namespace.

GraphNode

A node returned in graph traversal results.

MemoryGraphEngine

Thread-safe graph engine backed by a SQLite database.

Enums

EdgeType

How two memories are related.

Functions

open_from_env

Open a MemoryGraphEngine using DAKERA_DATA_DIR if set, otherwise :memory:.
