Struct InMemorySessionStore 

pub struct InMemorySessionStore { /* private fields */ }

In-memory session store using parking_lot::RwLock (not tokio — matches codebase pattern for locks never held across .await; parking_lot is adopted on the channel hot path for ~2× faster uncontended reads, see T2 in tasks/performance-audit-heartbit-core-2026-05-06.md).

impl SessionStore for InMemorySessionStore

fn create(&self, title: Option<String>) -> Result<Session, Error>

fn create_with_user( &self, title: Option<String>, user_id: &str, tenant_id: &str, ) -> Result<Session, Error>

Get a session by ID. Returns None if not found.

fn list(&self) -> Result<Vec<Session>, Error>

List all sessions (most recent first).

fn delete(&self, id: Uuid) -> Result<bool, Error>

Delete a session. Returns true if found and deleted.

fn add_message(&self, id: Uuid, message: SessionMessage) -> Result<(), Error>

Append a message to an existing session.

fn list_for_tenant(&self, tenant_id: &str) -> Result<Vec<Session>, Error>

List sessions scoped to a tenant (most recent first). Default: calls list() and filters in-memory.
