Trivial Change

Code

[ ] Packages, classes, and methods have a single domain of responsibility.
[ ] Packages, classes, and methods are grouped into cohesive and consistent domain model.
[ ] The code is canonical and the minimum required to achieve the goal.
[ ] Modules, libraries, and APIs are easy to use, robust (foolproof and not errorprone), and tested.
[ ] Logic and naming has clear narrative that communicates the accurate intent and responsibility of each module (e.g. method, class, etc.).
[ ] The code is algorithmically efficient and scalable for the whole application.

Architecture

[ ] Any required refactoring is completed, and the architecture does not introduce technical debt incidentally.
[ ] Any required build and release automations are updated and/or implemented.
[ ] Any new components follows a consistent style with respect to the pre-existing codebase.
[ ] The architecture intuitively reflects the application domain, and is easy to understand.
[ ] The architecture has a well-defined hierarchy of encapsulated components.
[ ] The architecture is extensible and scalable.
