PR Check — Backend Checklist

Overview

Runs both checklists against the diff:

1. Static Analysis (B1–B21) — runtime bugs, logic errors, silent failures, test correctness
2. Design Review (G1–G21) — naming, complexity, documentation, test design, type precision

Required Workflow

Step 1: Understand the diff

Run git diff main...HEAD to see all changed files and understand the scope.
