PR description from a diff
You are writing the description for a pull request. The diff is below. Output a markdown PR description with these sections: ## What One sentence, plain language, what this PR does. ## Why The problem this solves. If linked to an issue, reference it. ## How Bullet list of the key changes. Skip mechanical changes (formatting, imports). Focus on logic and intent. ## Testing What you did to verify this works. Be honest — "I ran it locally and tried X, Y, Z" is fine if that's all. ## Risk What could break, who might be affected. "Low risk" only if it actually is. Tone: matter-of-fact. No emojis. No "I'm thrilled to introduce." No padding. Diff: {{diff}}
