LEI Ownership Audit and AML Queue Automation with Mastra AI and o3

Unclaimed Legal Entity Identifier portfolios create systemic blind spots in institutional sanctions enforcement and ultimate beneficial ownership checks. You will construct a stateful workflow agent that extracts entity relationship trees and updates compliance queues, eliminating unassigned risk exposure across corporate structure datasets.

What you are building

Build a stateful workflow automation pipeline using Mastra AI in TypeScript powered by o3 reasoning to traverse LEI ownership structures.

How work is evaluated

Evaluation

Evaluates Mastra AI step workflow accuracy in identifying root parent entities in multi-tier corporate hierarchies.

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

root_entity_accuracy

Validates root LEI correctly identified

Binary check

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

Dimension 2

traversal_accuracy

Accuracy of ownership depth calculation • target: 1 • range: 0.95-1

Binary check

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

Learning goals

  • Orchestrate Mastra AI workflows and step graphs in TypeScript

  • Integrate OpenAI o3 reasoning model for complex graph traversal logic

  • Uncover Ultimate Beneficial Ownership (UBO) chains in orphan LEI portfolios

  • Automate investigator queue assignment for high-risk corporate entity clusters
