Design exercise: Code Review Systems

Diff understanding, intent, correctness, maintainability, risk ranking, review workflows, and actionable findings. Implement designOutline() returning non-empty values for: changeIntent, riskFinding, actionableEvidence. Each value must name a concrete mechanism or decision.

The mechanism

Useful review connects a changed line to behavior and risk. Findings need evidence, severity, scope, and a concrete remediation—not generic style commentary.
