Quick Summary

Validate a sequential batch of company-contact-role associations against existing records and strict capacity constraints.
Enforce rules for uniqueness, maximum 5 contacts per role per company, and maximum 2 roles per contact per company.
Update system state dynamically as valid associations are processed, affecting subsequent validations.

What This Tests

Efficient state management using Hash Tables for O(1) lookups and updates.
Handling composite keys and nested collections to track multi-dimensional constraints.
Sequential simulation where intermediate results influence future steps.
Implementing layered validation logic with specific failure reasons.
