Enum GraphRetrievalStrategy 

pub enum GraphRetrievalStrategy {
    Synapse,
    Bfs,
    AStar,
    WaterCircles,
    BeamSearch,
    Hybrid,
}

Graph traversal algorithm selector for a graph recall call.

Mirrors zeph_config::memory::GraphRetrievalStrategy so that zeph-context (Layer 1) can pass a strategy selection through GraphRecallParams without depending on zeph-config’s concrete enum. Concrete dispatch onto SemanticMemory methods happens in zeph-agent-context::memory_backend (Layer 4).

Examples

use zeph_common::memory::GraphRetrievalStrategy;

assert_eq!(GraphRetrievalStrategy::default(), GraphRetrievalStrategy::Synapse);

Variants

Synapse

SYNAPSE spreading activation (default, existing behavior).

Bfs

Hop-limited BFS traversal (pre-SYNAPSE behavior).

AStar

A* shortest-path traversal.

WaterCircles

Concentric BFS expanding outward from seed nodes.

BeamSearch

Beam search: keep top-K candidates per hop.

Hybrid

Dynamic: LLM classifier selects strategy per query.
