Struct AppState 

pub struct AppState {
    pub db: Db,
    pub embedder: Arc<Option<Embedder>>,
    pub vector_index: Arc<Mutex<Option<VectorIndex>>>,
    pub federation: Arc<Option<FederationConfig>>,
    pub tier_config: Arc<TierConfig>,
    pub scoring: Arc<ResolvedScoring>,
}

Composite daemon state (issue #219/v0.7 prep).

Previously the Axum router held only Db. Closing the HTTP embedding gap (semantic recall silently missed HTTP-stored memories because the daemon never generated embeddings) requires the embedder and the in-memory HNSW index to be reachable from write handlers. We introduce AppState and use FromRef so every existing State<Db> handler keeps working unchanged — only the write paths opt into State<AppState> to pick up the embedder and vector index.

Fields

db: Db

embedder: Arc<Option<Embedder>>

vector_index: Arc<Mutex<Option<VectorIndex>>>

federation: Arc<Option<FederationConfig>>

v0.7 federation config — Some when --quorum-writes N + --quorum-peers are configured at serve time. Writes fan out to peers via FederationConfig::broadcast_store_quorum when this is Some.

tier_config: Arc<TierConfig>

Resolved TierConfig for this daemon. Exposed so HTTP endpoints that mirror MCP tools (notably /capabilities) can reuse the MCP-side report builder without re-parsing config.

scoring: Arc<ResolvedScoring>

v0.6.2 (S18): resolved recall scoring config — tier half-lives, legacy-scoring toggle. Exposed so recall_memories_get / recall_memories_post can call db::recall_hybrid (semantic blend) when the embedder is loaded, mirroring how the MCP memory_recall handler already wires it (src/mcp.rs:1157). Prior to this, HTTP recall was keyword-only regardless of embedder availability — scenario-18 surfaced the gap.

Trait Implementations

impl Clone for AppState

fn clone(&self) -> AppState

Returns a duplicate of the value.
