Analyze temperature telemetry logs and maintenance records for port cold-store facilities. Identify mechanical equipment breakdowns, evaluate thermal excursions, and generate verified liability dossiers using OpenAttestation wrappers for facility loss attribution.
What you are building
The core problem, expected build, and operating context for this challenge.
Analyze temperature telemetry logs and maintenance records for port cold-store facilities. Identify mechanical equipment breakdowns, evaluate thermal excursions, and generate verified liability dossiers using OpenAttestation wrappers for facility loss attribution.
Cold-chain claims surveyor and cargo assurance officer
Ingest facility cold-store temperature telemetry and scheduled maintenance logs.
Identify thermal excursion events corresponding to mechanical equipment failures lasting beyond safe thresholds.
Wrap equipment failure records and impact assessments into OpenAttestation schemas.
Synthesize itemized liability dossiers attributing loss to specific facility segments or contractors.
Dashboard mapping facility sensor zones with thermal trends, a maintenance schedule overlay, and a drawer for generating OpenAttestation liability claims.
Generate synthetic cold-store facility telemetry time-series and maintenance logs, paired with OpenAttestation v2 wrapper templates from source 2. Starter examples below are synthetic. They are not downloaded records.
OpenAttestation Implements OpenAttestation v2 wrapDocument logic for verifiable facility equipment breakdown and liability declarations.
langgraph, @govtechsg/open-attestation, pydantic, fastapi. LangGraph orchestrates the stateful evaluation cycle connecting anomaly detection, maintenance cross-referencing, and OpenAttestation claim wrapping. Reasoning model capable of cross-referencing sensor logs with maintenance schedules and formatting structured liability schemas.
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.
Detects thermal excursions exceeding target temperatures lasting more than three continuous hours.
Attributes breakdown liability to 'maintenance_contractor' if maintenance is missed, otherwise 'manufacturer'.
Calculates spoilage risk amount at 10% of inventory value for every full hour of excursion beyond the initial 3 hours.
Generates valid OpenAttestation v2 wrapped document objects for confirmed equipment failures.
