Refactor Process Task

Problem

A Ruby team needs help with a task in this area:

Enforces a disciplined refactoring process for Ruby code: ONE atomic transformation at a time, characterization tests MUST exist and be Green BEFORE any edit, run tests after EVERY single step, rollback immediately on Red (no debugging in broken state), no behavior changes mixed with refactoring.

The team has asked for a concise implementation artifact that a reviewer can inspect without needing to observe the agent's process.

Output

Create answer.md with:

• a short plan for the work
• the concrete Ruby-oriented artifact or recommendation
• the verification steps or quality gates that should be run
• any assumptions that affect the result
