How we used FalkorDB, Graph Theory (WCC, Betweenness, PageRank), and Multi-Agent simulation to catch breaking ecosystem changes before merge

Описание и применение

ShadowGraph использует FalkorDB и графовые алгоритмы для выявления и предотвращения разрушающих изменений в интеграциях Home Assistant, позволяя разработчикам обнаруживать проблемы до слияния.

Задача

A refactor that moved sensor entity classes into a separate module broke 32 custom integrations that depended on internal symbols, risking runtime failures for users.

Результат

ShadowGraph enabled early detection of 32 integration breakages, provided migration patches, and extended impact analysis beyond core tests.

Рабочий процесс

• Build dependency graph via Python AST analysis
• Create isolated graph copy in FalkorDB
• Simulate removal/change of symbols
• Identify integrations that fail during import vs. runtime
• Use AI agents to verify potential breakages
• Generate draft patches for maintainers

Доказательства

32 custom integrations depended on internal symbols that the refactor stopped exposing.
