Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Process simulated open62541 server telemetry to audit factory equipment against site acceptance specifications. Flag missing telemetry nodes and compile acceptance sign-off packets.

Factory Integration Specialist

Parse node ID structures and value definitions from simulated open62541 server snapshots.

Compare exposed node definitions against contract equipment acceptance checklists.

Evaluate telemetry sampling jitter and sensor error flags across commissioning tests.

Construct a standardized acceptance packet highlighting missing or out-of-spec node definitions.

Browser-based commissioning checklist view with node discovery statuses and sign-off export controls.

Construct mock JSON node dumps mimicking open62541 information models with status codes and engineering units. Starter examples below are synthetic. They are not downloaded records.

open62541 OPC UA Uses open62541 architecture principles where OPC UA nodes and server information models define equipment capabilities.

mastra-ai, typescript, zod. Mastra AI provides deterministic workflow orchestration to walk complex hierarchical information models. Fast reasoning API capable of reconciling tabular schema checklists against observed telemetry nodes.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Flags missing mandatory nodes according to the site acceptance checklist.

Detects invalid OPC UA StatusCode values during test runs.

Generates a verified acceptance packet with sign-off recommendations.
