Pydantic AI Physical Process Anomaly Sentinel for Water Utilities

Cyber-physical attacks on water treatment facilities can alter valve states and dosage controls without generating network alerts. Build a type-safe anomaly detection agent using Pydantic AI to validate telemetry inputs against physics-based process bounds. The sentinel must detect physical parameter manipulation with zero false negatives while maintaining sub-second inference speed.

What you are building

Build a Pydantic AI agent with strict type validation to detect physical process parameter manipulation in water treatment networks.

How work is evaluated

Evaluation

Evaluates physical process attack detection accuracy and structured Pydantic model response validity.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

zero_false_negatives

Ensures no dangerous physical over-dosing events are missed

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

type_validation_rate

Percentage of agent outputs matching Pydantic response schema • target: 1 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Implement a Pydantic AI agent with structured result types for physical safety validation

  • Define Pydantic models enforcing hydraulic and chemical mass balance constraints

  • Detect 'stealth' physical parameter tampering occurring below network alert thresholds

  • Provide deterministic diagnostic reasonings for utility operator intervention
