Struct RuntimeConfig 

pub struct RuntimeConfig {
    pub db_path: Option<PathBuf>,
    pub default_namespace: Namespace,
    pub embedding_model: Option<EmbeddingModel>,
    pub gate: GateRef,
    pub packs: Vec<String>,
    pub backend_id: BackendId,
}

Runtime configuration.

Per ADR-028, the db_path and embedding_model fields are deprecated in favour of constructing the backend externally and calling KhiveRuntime::from_backend. They remain for backward compatibility with tests and single-binary deployments.

Fields

db_path: Option<PathBuf>

Path to the SQLite database file. None = in-memory (tests).

Deprecated: use KhiveRuntime::from_backend instead. The boot path constructs backends from khive.toml (AppConfig) and passes them to from_backend. Direct db_path usage persists only in tests.

default_namespace: Namespace

Namespace used when no explicit namespace is provided.

embedding_model: Option<EmbeddingModel>

Local embedding model. None disables embedding and hybrid vector search; hybrid_search then falls back to text-only.

Deprecated: per ADR-028/ADR-031, embedding engines move to a per-pack EmbedderRegistry. This field persists for backward compatibility until the embedder registry is fully plumbed.

gate: GateRef

Authorization gate consulted before each verb dispatch (ADR-029). Default: AllowAllGate (permissive). For production policy enforcement, plug in a Rego- or capability-witness-backed impl.

packs: Vec<String>

Names of packs the transport layer should register into the VerbRegistry. The transport layer (e.g. khive-mcp) reads this list and instantiates the matching concrete pack types. Unknown names are reported as errors by the transport, not silently ignored. Default: ["kg"].

backend_id: BackendId

Identifies this runtime’s backend in a multi-backend deployment (ADR-009, ADR-028).

Set by the boot path when constructing per-pack runtimes from khive.toml. Single-backend deployments use the default BackendId::MAIN.
