Build a GLEIF Restructuring Lineage and Ultimate Parent Tracker

Trace historical corporate acquisitions and spin-offs using GLEIF relationship records. Map multi-generational successor entity networks to definitively compute the ultimate parent entity after complex restructuring events.

Corporate Due Diligence Investigator

Parse simplified entity identifier records and historical restructuring query parameters.

Traverse multi-generational corporate relationship trees to resolve cyclic or split entity relationships.

Calculate the post-restructuring ultimate parent entity by tracking the terminal successor node in the directed acyclic graph.

Output an interactive restructuring chronology terminating in the computed ultimate parent entity.

A DAG-based lineage graph viewer highlighting the ultimate parent node and the path of corporate successor transitions.

Construct synthetic multi-tier merger event datasets matching GLEIF relationship records, provided as simplified synthetic app records, not complete official schema files. Starter examples below are synthetic. They are not downloaded records.

GLEIF API GLEIF API corporate relationship structures (parent and child relationships and Golden Copy data models).

langgraph, fastapi, networkx. Manages cyclical traversal states while resolving multi-generation corporate successor graphs into an ultimate parent node. Instruction-tuned agent model for traversing corporate relationships and synthesizing lineage narratives.

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.

Successfully calculates the terminal ultimate parent entity from a multi-hop predecessor chain.

Accurately traverses split events and determines which branch retains the primary operating lineage.

Emits an exportable graph chronology payload showing the exact path to the ultimate parent.

Maintains non-accusatory corporate structural analysis without making definitive sanctions or freeze rulings. Use mock external writes. Require human review before any real deployment.
