AI Agent

Configuration for at-least-once delivery guarantees.

Attributes:
enabled: Toggle delivery guarantees
ack\_timeout: Seconds to wait for ACK before retrying
max\_retries: Maximum retry attempts
retry\_backoff: Exponential backoff multiplier
message\_ttl: How long to retain unacknowledged messages (seconds)
store\_backend: Message store backend — `"sqlite"` (default,
zero-dependency durable store so the at-least-once guarantee
survives a gateway restart/redeploy), `"redis"` (durable +
multi-process horizontal fan-out) or `"memory"` (explicit,
ephemeral opt-out for testing/single-process throwaway use).
