To design modular Python architectures, you delineate explicit module boundaries and data contracts to enforce clear ownership. This approach reduces cross-cutting coupling and clarifies data flow, making codebases easier to maintain, test, and refactor.

Breaking god classes requires partitioning concerns by applying structured refactor guidelines that isolate changes and enforce functional core and imperative shell separation. This maintains testability while untangling dependencies across multiple Python packages.

You need to establish module ownership and data contracts when managing tangled dependencies and unclear ownership that hinder safe refactoring. Delineating responsibilities ensures predictable interfaces and explicit data flow for future codebase evolution.

Plan a multi-package refactor by applying structured guidelines to partition concerns, isolate changes, and enforce clear module boundaries. This approach maintains testability by promoting predictable interfaces and functional core separation.

Functional core and imperative shell separation works for restructuring Python modules by enforcing clear boundaries between pure logic and side effects. This improves readability and ensures explicit data flow across module contracts.

Unclear module ownership hinders maintenance because tangled dependencies and god classes obscure data contracts and cross-cutting coupling. Establishing explicit module boundaries improves understandability, readability, and safe refactoring.
