Struct StorageSection 

pub struct StorageSection {
    pub backend: String,
}

S5.1: storage / retrieval backend configuration.

Controls which RetrievalBackend implementation is used for memory candidate generation. The broker (scoring, floors, rerank, compression) is backend-agnostic and is NOT affected by this setting.

#[serde(default)] keeps every pre-S5 project.toml loading cleanly (they get backend = "flat", which is exactly today’s FTS + usearch-ANN behaviour).

Fields

backend: String

Which retrieval backend to use.

Value	Behaviour
"flat"	FTS + usearch HNSW ANN (default)
"graph-lite"	flat, plus 2-hop BFS over memory_edges with hop decay
"graph"	petgraph backend (feature graph; remote server only)

Unknown values fall back to "flat" with a warning.

All three are implemented in kimetsu_brain::backend. Note that graph-lite only differs from flat once the edge table has non-supersedes edges in it — run kimetsu brain graph build first, or it degenerates to flat retrieval. The published BEAM 100K figure (73.3%, vs 62.3% flat) was measured on graph-lite with edges built.
