DeadLetterPolicyProtocol
Defined in the protocols module.AI Agent Protocol for the durable-queue dead-letter decision. Pure, import-free decision contract consumed by the outbound queue’s
drain and the inbound journal’s redelivery/replay paths. The runtime
supplies typed facts about a repeatedly-failing entry (its attempts,
the first_seen_epoch it was first received, the current now_epoch,
and a coarse error_class) and the policy returns a
:class:DeadLetterDecision. Concrete queue state and side effects (SQLite
rows, DLQ enqueue) stay in the implementation; this keeps the policy
injectable and testable in isolation, symmetric with
:class:SendPolicyProtocol / :class:RateLimitPolicyProtocol.
A config-driven default (:class:AttemptAndAgeDeadLetterPolicy) is
provided for the common “poison vs transient” case.
Methods

DeadLetterDecision for the supplied facts.Source
