Introduction
dsh-lattice-runtime
Runtime engine for DSH Lattice V1.
Scope
This package implements the runtime side of the DSH Lattice contract:
- In-memory and durable JSONL append-only event stores with replay and atomic append semantics.
- Task and Assignment state machines.
- Central durable mailbox with direct/group/broadcast routing, offline outbox, dead-letter queue, TTL, ack, at-least-once delivery, and deterministic idempotent deduplication.
- Adapter registry and required-vs-observed capability negotiation.
- Session decision engine (auto/reuse/fork/new) with compatibility fingerprint, fail-loud forced reuse, and deterministic handoff bundles.
LatticeRuntimewithutoRun,agentMessage,status,cancel, andrecover.- Event projections and secret-safe structured errors.
All external side effects are kept behind adapter interfaces; tests use fake adapters.
Usage
import { LatticeRuntime, InMemoryEventStore } from "dsh-lattice-runtime";
const runtime = new LatticeRuntime({ stores, adapters });
const result = await runtime.utoRun(request);
