## Behavioral notes
- As an interface, this type defines no executable behavior of its own; behavior is determined by its implementation(s).*

## Constraints and usage notes
- Callers should depend on this interface rather than the concrete implementation(s) (`BillQueryProvider`) to preserve testability.*

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
