More than extraction — structural relationships
Business functions don't exist in isolation. A premium calculation calls a risk lookup. An authorization gate feeds a settlement pipeline. Understanding these relationships is understanding how your enterprise actually works.
AI scientists at Phase Change reveal two fundamental patterns in how functions compose: they chain sequentially (composition) or combine in parallel (aggregation). Every enterprise system is built from these two patterns.
COBOL Colleague maps these patterns deterministically — not by guessing from code patterns, but by tracing actual control flow and data dependencies through the knowledge graph.
