Challenge brief

What you are building

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

Parse cold-chain IoT temperature records during overland transit between Malaysia and Singapore. Bundle temperature breaches into verifiable TradeTrust packages and generate consignee spoilage risk notifications.

Perishable Cargo Quality Inspector

Ingest IoT temperature data streams and checkpoint timestamp logs for reefer transport trucks.

Identify sustained temperature excursion events exceeding product perishability thresholds.

Wrap raw sensor records and breach telemetry into an OpenAttestation verifiable certificate.

Synthesize an urgent consignee cargo status bulletin detailing spoilage risks and quarantine instructions.

A cold-chain monitor displaying transit temperature curves, breach interval highlights, OpenAttestation document hashes, and client notice previews.

Use mock IoT sensor logs alongside official @govtechsg/open-attestation schemas for certificate packaging. Starter examples below are synthetic. They are not downloaded records.

OpenAttestation Employ OpenAttestation wrapping and signature verification methods to authenticate cold-chain excursion logs.

mastra-ai, @govtechsg/open-attestation, typescript. Mastra AI manages end-to-end data transformation workflows and schema validations with typed agent state. Hosted reasoning model capable of synthesizing technical quarantine briefs.

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 cumulative temperature excursions over 4°C exceeding 30 continuous minutes.

Generates OpenAttestation v2 wrapped document containing uncorrupted raw telemetry hashes.

Drafts quarantine advisories for high-risk perishable cargo items.

Requires supervisor review before marking cargo as cleared or quarantined.
