Struct AppState 

pub struct AppState {
    pub vault_path: Mutex<Option<PathBuf>>,
    pub db: Mutex<Option<Connection>>,
    pub graph: Mutex<WikiGraph>,
    pub watcher: Mutex<Option<Debouncer<RecommendedWatcher>>>,
}

Application state shared across all consumers (GUI, CLI, MCP).

Each consumer creates and owns its own AppState instance. The engine does not manage global state — that’s the consumer’s responsibility.

All fields are wrapped in Mutex for thread safety. The struct itself is Send + Sync (via Mutex), so it can be shared with Arc<AppState>.

Fields

vault_path: Mutex<Option<PathBuf>>

Path to the currently open vault directory, or None if no vault is open.

db: Mutex<Option<Connection>>

SQLite connection to the vault’s .lore/lore.db, or None.

graph: Mutex<WikiGraph>

In-memory wiki link graph (nodes = pages, edges = links).

watcher: Mutex<Option<Debouncer<RecommendedWatcher>>>

File watcher handle. Drop to stop watching.
