ADR-021: Edge identity uses consumer-defined keys
Status
Accepted
Context
Edges need unique identity within a graph. Auto-generated UUIDs vs consumer-defined keys affect how edges are referenced and updated.
Decision
Edges use (graphId, key) as their unique identity, where key is consumer-defined. This matches the metagraph model where consumers control identifiers. For anonymous edges (common in simple graphs), key can be auto-generated.
Consequences
- Consumers can reference edges by meaningful keys (e.g.,
"call-001→call-002") - Updates use the consumer's key, not a generated UUID
- Anonymous edges can have null or auto-generated keys
