}

Daemon-wide state shared across all RPC connections.

Fields

config: Arc<RwLock<Config>>

Live config behind a read-write lock so config/set can mutate without a full daemon reload. Mirrors the gateway’s Arc<RwLock<Config>> pattern.

sessions: Arc<SessionStore>

In-memory session store for active RPC sessions.

session_backend: Option<Arc<dyn SessionBackend>>

Persistent session backend (SQLite / JSONL) for history and session metadata. None when persistence is disabled.

memory: Option<Arc<dyn Memory>>

Memory subsystem (dyn Memory from zeroclaw-api).

cost_tracker: Option<Arc<CostTracker>>

Cost tracking. None when cost tracking is disabled.

event_tx: Option<Sender<Value>>

Daemon-wide event broadcast. RPC handlers subscribe to forward events as JSON-RPC notifications (logs/subscribe).

reload_tx: Option<Sender<bool>>

Write true to trigger a daemon-level config reload. Mirrors the gateway’s /admin/reload mechanism.

approval_pending: Arc<ApprovalPendingMap>

In-flight approval requests waiting for session/approve RPC calls.

tui_registry: Arc<TuiRegistry>

Live TUI client registry. Tracks connected TUI sessions by UID. Source of truth for “which TUIs are connected right now.”

acp_session_store: Option<Arc<AcpSessionStore>>

ACP session persistence. Opened (and the DB file created) at daemon boot under <data_dir>/sessions/acp-sessions.db. None when the store could not be opened (read-only FS, bad perms) — callers must treat persistence as best-effort.
