    pub community_summary_max_prompt_bytes: usize,
    pub community_summary_concurrency: usize,
}

Configuration for the knowledge graph memory subsystem ([memory.graph] TOML section).

Security

Entity names, relation labels, and fact strings extracted by the LLM are stored verbatim without PII redaction. This is a known pre-1.0 MVP limitation. Do not enable graph memory when processing conversations that may contain personal, medical, or sensitive data until a redaction pass is implemented on the write path.

Fields

enabled: bool

extract_model: String

max_entities_per_message: usize

max_edges_per_message: usize

community_refresh_interval: usize

entity_similarity_threshold: f32

extraction_timeout_secs: u64

use_embedding_resolution: bool

entity_ambiguous_threshold: f32

max_hops: u32

recall_limit: usize

expired_edge_retention_days: u32

Days to retain expired (superseded) edges before deletion. Default: 90.

max_entities: usize

Maximum entities to retain in the graph. 0 = unlimited.
