Decompose PR for Learning

Turn a multi-concern PR into a sequence of focused commits that each do one thing.

Why This Exists

Complex PRs are hard to understand because changes interleave. A single function might have three modifications serving different purposes. By decomposing into atomic commits, you can:

• Study each change in isolation
• Understand the dependency order (what enables what)
• See which tests correspond to which changes
• Build intuition for the codebase incrementally

When to Use

• You're reviewing a PR and can't follow the logic
• You're onboarding and want to understand a feature's implementation
• You're debugging and need to isolate which change caused an issue
• You're learning a codebase through its PRs
