Reopen durable sessions

The executable scenario is examples.durable_agent.

python examples/durable_agent.py

The scenario creates a SQLite-backed application, completes one run, constructs a new runtime over the same file, and verifies that the session, run, messages, and events reopen.

Compose persistence

from agentmuru import Application, Runtime, SQLitePersistence

persistence = SQLitePersistence("agentmuru.db")
application = Application(
    agent=agent,
    session_store=persistence.sessions,
    artifact_store=persistence.artifacts,
)
runtime = Runtime(application, approvals=persistence.approval_service())

Use the stores from the same SQLitePersistence object so sessions, artifacts, and approval records share one database and schema lifecycle.

Make submissions idempotent

run = await runtime.submit(
    session.id,
    "persist this",
    idempotency_key="client-request-1842",
)

Retrying with the same key returns the bound run instead of creating another run.

Reopen safely

Create a new persistence object and runtime after the first process is fully stopped. The bundled SQLite profile is designed for one active AgentMuru runtime process per database file. See SQLite operations for locking, backups, and recovery.
