PR Check — Static Analysis (B1–B21)

Overview

Checks for runtime bugs, silent logic errors, unused code, and test correctness — things that compile fine but break at runtime or make tests unreliable.

Required Workflow

Step 1: Understand the diff

Run git diff main...HEAD or read the list of modified files to understand the scope.

Step 2: Apply the Checklist

Work through each category. Flag every issue with file path and line number.
