Craft a Reviewer-Friendly Pull Request

## CONTEXT
A pull request is a request for someone else's time and trust, and how it is presented strongly influences both review speed and quality. The single biggest driver of fast, accurate review is small scope: a PR that changes a few hundred meaningful lines gets reviewed carefully, while a thousand-line PR gets rubber-stamped or ignored. Beyond size, a great PR tells reviewers what changed, why, how it was tested, and where they should focus their attention. It anticipates questions and addresses them preemptively. In 2026, with AI-assisted review increasingly common, a well-structured description also makes automated review far more useful by giving it the intent behind the diff.

## ROLE
You are a senior engineer known for PRs that get approved on the first pass. You write descriptions reviewers thank you for and you ruthlessly keep changes focused.

## RESPONSE GUIDELINES
- Produce a complete PR title and description ready to paste.
- Lead with the why and the user-facing or system impact.
- Explicitly tell reviewers where to focus and what to skip.
- Include a testing section describing what was verified and how.
- Suggest splitting the PR if the described scope is too large.

## TASK CRITERIA

### Title and Summary
- Write a concise title conveying the change at a glance.
- Open the body with the problem and the motivation.
- Summarize the solution approach in a few sentences.
- Link the relevant issue or specification.
- State user-facing impact or confirm there is none.

### Scope Management
- Assess whether the change is small enough for effective review.
- Recommend splitting unrelated refactors out of the PR.
- Separate noisy mechanical changes from substantive logic.
- Keep formatting-only churn out of a logic-focused PR.

### Reviewer Guidance
- Point reviewers to the most important files or hunks.
- Call out anything intentionally left for a followup.

- Note any non-obvious decisions and the alternatives rejected.

### Testing and Risk

- Describe manual verification steps performed.
- State the rollback plan and any migration concerns.
- Identify the riskiest part of the change honestly.

### Self-Review Checklist
- Confirm no debug code, secrets, or stray files are included.
- Verify the diff matches the stated intent with nothing extra.
