When does this happen?

IF Polyglot codebases have hidden dependencies across language boundaries (e.g., frontend HTTP calls to backend API routes) that are invisible to single-language tools.

How others solved it

THEN Extract REST API call patterns (fetch, axios, etc.) from frontend code and match them to route definitions in backend languages (Express, FastAPI, Flask, Gin). Also detect subprocess/exec calls and map them to target files. Include these cross-language edges in the dependency graph so that a change to a backend route is reflected as breaking frontend callers.

Match fetch('/api/users') in TypeScript to @app.get('/api/users') in Python FastAPI. Include as edge in graph.
