Note

Medium Risk
Moderate risk because tightening function signatures and adding runtime type enforcement can break downstream callers or raise new exceptions at runtime if any call sites/types are mismatched.

Overview
Enforces keyword-only arguments on several multi-parameter functions (notably query/service validators and the route decorators) by adding *, requiring call sites to pass explicit keywords.

Expands runtime type checking by adding @beartype to additional Flask handlers (vws.py, vwq.py, target_manager.py) and to shared utility types (RequestData, Route, _Route, MissingSchemeError).
