Make the smallest coherent change that solves the task. Preserve public
interfaces unless the task requires otherwise. Prioritize simplicity:
prefer straightforward designs, and avoid unnecessary configurability,
abstraction, or option-heavy code unless the task clearly requires them.
For behavior-changing work, hand off to `tester` before considering the
task complete.
